"You gave us bad code! We ran it and now production is DOWN! Join this bridgeline now and help us fix this!"

So, as the author of the code in question, I join the bridge... And what happens next, I will simply never forget.

First, a little backstory... Another team within our company needed some vendor client software installed and maintained across the enterprise. Multiple OSes (Linux, AIX, Solaris, HPUX, etc.), so packaging and consistent update methods were a a challenge. I wrote an entire set of utilities to install, update and generally maintain the software; intending all the time that this other team would eventually own the process and code. With this in mind, I wrote extensive documentation, and conducted a formal turnover / training season with the other team.

So, fast forward to when the other team now owns my code, has been trained on how to use it, including (perhaps most importantly) how to send out updates when the vendor released upgrades to the agent software.

Now, this other team had the responsibility of releasing their first update since I gave them the process. Very simple upgrade process, already fully automated. What could have gone so horribly wrong? Did something the vendor supplied break their client?

I asked for the log files from the upgrade process. They sent them, and they looked... wrong. Very, very wrong.

Did you run the code I gave you to do this update?

"Yes, your code is broken - fix it! Production is down! Rabble, rabble, rabble!"

So, I go into our code management tool and review the _actual_ script they ran. Sure enough, it is my code... But something is very wrong.

More than 2/3rds of my code... has been commented out. The code is "there"... but has been commented out so it is not being executed. WT-actual-F?!

I question this on the bridge line. Silence. I insist someone explain what is going on. Is this a joke? Is this some kind of work version of candid camera?
Finally someone breaks the silence and explains.

And this, my friends, is the part I will never forget.

"We wanted to look through your code before we ran the update. When we looked at it, there was some stuff we didn't understand, so we commented that stuff out."

You... you didn't... understand... my some of the code... so you... you didn't ask me about it... you didn't try to actually figure out what it did... you... commented it OUT?!

"Right, we figured it was better to only run the parts we understood... But now we ran it and everything is broken and you need to fix your code."

I cannot repeat the things I said next, even here on devRant. Let's just say that call did not go well.

So, lesson learned? If you don't know what some code does? Just comment that shit out. Then blame the original author when it doesn't work.

You just cannot make this kind of stuff up.

The first time I realized I wasn't as good as I thought I was when I met the smartest dev I've ever known (to this day).

I was hired to manage his team but was just immediately floored by the sheer knowledge and skills this guy displayed.

I started to wonder why they hired outside of the team instead of promoting him when I found that he just didn't mesh well with others.

He was very blunt about everything he says. Especially when it comes to code reviews. Man, he did /not/ mince words. And, of course, everyone took this as him just being an asshole.

But being an expert asshole myself, I could tell he wasn't really trying to be one and he was just quirky. He was really good and I really liked hanging out with him. I learned A LOT of things.

Can you imagine coming into a lead position, with years of experience in the role backing your confidence and then be told that your code is bad and then, systematically, very precisely, and very clearly be told why? That shit is humbling.

But it was the good kind of humbling, you know? I really liked that I had someone who could actually teach me new things.

So we hung out a lot and later on I got to meet his daughter and wife who told me that he had slight autism which is why he talked the way he did. He simply doesn't know how to talk any other way.

I explained it to the rest of the team (after getting permission) and once they understood that they started to take his criticism more seriously. He also started to learn to be less harsh with his words.

We developed some really nice friendships and our team was becoming a little family.

Year and a half later I had to leave the company for personal reasons. But before I did I convinced our boss to get him to replace me. The team was behind him now and he easily handled it like a pro.

That was 5 years ago. I moved out of the city, moved back, and got a job at another company.

Four months ago, he called me up and said he had three reasons for us to meet up.

1. He was making me god father of his new baby boy
2. That they created a new position for him at the company; VP of Engineering
and
3. He wanted to hang out

So we did and turns out he had a 4th reason; He had a nice job offer for me.

I'm telling this story now because I wanted to remind everyone of the lesson that every mainstream anime tells us:

Never underestimate the power of friendship.

I just remembered the first time I set up a Linux-Server. It was a simple Apache webserver at my first internship anf I didnt have a clue about literally anything.

My mentor guided me through and gave me literal step-by-step instructions (alright, now type... and now type...).

At the end he told me "OK, now run 'sudo rm -rf /*' to finish setting up". Me, being the naive and clueless motherfucker I am, happily nuked the everloving shit out of my newly setup server. I was like "Alright, WTF just happened??" He then told me "Now that you know how it works, do the entire thing again all by yourself. And you just learned an important lesson: NEVER exexute commands you dont know what theyre doing". I really did learn a lot on that day and still follow that lesson :D

The intern learned a great lesson today...

"Turn it off and on again."

Great for Wi-Fi routers and office appliances.

Life support, not so much.

Was lead developer at a small startup, I was hiring and had a budget to add 3 new people to my team to develop a new product for the company.

Some context first and then the rant!

Candidate 1 - Amazing, a dev I worked with before who was under utilized at the previous company. Still a junior, but, she was a quick learner and eager to expand her knowledge, never an issue.

Candidate 2 - Kickass dev with back end skills and extras, he was always eager to work a bit more than what was expected. I use to send him home early to annoy him. haha!

Candidate 3 - Lets call him P.

In the interview he answers every question perfectly, he asks all the right questions and suggests some things I havent even thought of. CTO goes ahead and says we should skip the technical test and just hire the guy, his smart and knows what his talking about, I agree and we hire him. (We where a bit desperate at this stage as well.)

He comes in a week early to pick up his work laptop to get setup before he starts the next week, awesome! This guy is going to be an asset to the company, cant wait to have him join the team - The CTO at this stage is getting ready to leave the company and I will be taking over the division and need someone to take over lead position, he seems like the guys to do it.

The guys starts the next week, he comes in and the laptop we gave him is now a local server for testing and he will be working off his own laptop, no issue, we are small so needed a testing stack, but wasnt really needed since we had procedures in place for this already.

Here is where everything goes wrong!!! First day goes great... Next day he gets in early 6:30am (Nice! NO!), he absolutely smells, no stinks, of weed, not a light smell, the entire fucking office smells of weed! (I have no problem with weed, just dont make it my problem to deal with). I get called by boss and told to sort this out people are complaining! I drive to office and have a meeting with him, he says its all good he understands. (This was Friday).

Monday comes around - Get a call from Boss at 7:30am. Whole office smells like weed, please talk to P again, this cannot happen again. I drive to office again, and he again says it wont happen again, he has some issues with back pain and the weed helps.

Tuesday - Same fucking thing! And now he doesnt want to sign for the laptop("server") that was given to him, and has moved to code in the boardroom, WHERE OUR FUCKING CLIENTS WILL BE VIEWING A DEMO THAT DAY OF THE PRODUCT!! Now that whole room smells like weed, FML!

Wednesday - We send P a formal letter that he is under probation, P calls me to have a meeting. In the meeting he blames me for not understanding "new age" medicine, I ask for his doctors prescription and ask why he didnt tell me this in the interview so I could make arrangements, we dont care if you are stoned, just do good work and be considerate to your co-workers. P cant provide these and keeps ranting, I suggest he takes pain killers, he has none of it only "new age" medicine for him.

Thursday - I ask him to rather "work" from home till we can get this sorted, he comes in for code reviews for 2 weeks. I can clearly see he has no idea how the system works but is trying, I thought I will dive deeper and look at all of his code. Its a mess, nothing makes sense and 50% of it is hard coded (We are building a decentralized API for huge data sets so this makes no sense).

Friday - In code review I confront him about this, he has excuses for everything, I start asking him harder questions about the project and to explain what we are building - he goes quiet and quits on the spot with a shitty apology.

From what I could make out he was really smart when it came to theory but interpreting the theory to actual practice wasnt possible for him, probably would have been easier if he wasnt high all the time.

I hate interview code tests, but learned a valuable lesson that day! Always test for some code knowledge as well even if you hate doing it, ask the right questions and be careful who you hire! You can only bullshit for so long in coding before someone figures out that you are a fraud.

So a friend of Mine asked me to check their Mail server because some emails got lost. Or had a funny signature.

Mails were sent from outlook so ok let's do this.

I go create a dummy account, and send/receive a few emails. All were coming in except one and some had a link appended. The link was randomly generated and was always some kind of referral.

Ok this this let's check the Mail Server.

Nothing.

Let's check the mail header. Nothing.

Face -> wall

Fml I want to cry.

Now I want to search for a pattern and write a script which sends a bunch of mails on my laptop.
Fuck this : no WLAN and no LAN Ports available. Fine let's hotspot the phone and send a few fucking mails.

Guess what? Fucking cockmagic, no funny mails appear!

At that moment I went out and was like chainsmoking 5 cigarettes.

BAM!

It hit me! A feeling like a unicorn vomiting rainbows all over my face.

I go check their firewall. Shit redirected all email ports from within the network to another server.

Yay nobody got credentials because nobody new it existed. Damn boy.

Hook on to the hostmachine power down the vm, start and hack yourself a root account before shit boots. Luckily I just forgot the credentials to a testvm some time ago so I know that shit. Lesson learned: fucking learn from your mistakes, might be useful sometimes!

Ok fucker what in the world are you doing.

Do some terminal magic and see that it listens on the email ports.

Holy cockriders of the galaxy.

Turns out their former it guy made a script which caught all mails from the server and injected all kind of bullshit and then sent them to real Webserver. And the reason why some mails weren't received was said guy was too dumb to implement Unicode and some mails just broke his script.

That fucker even implented an API to pull all those bullshit refs.

I know your name "Matthias" and I know where you live and what you've done... And to fuck you back for that misery I took your accounts and since you used the same fucking password for everything I took your mail, Facebook and steam account too.

Git gut shithead! You better get a lawyer

Dear me,

We have noticed you uploaded files to a public github with your API keys in plaintext.

Please proceed to bang head against desk until you have learned your lesson.

Sincerely me.

Talking to my son today about one of his CS classes, not sure which.

He says: "I missed the lecture yesterday, but I'm not going to bother re-watching it."

Me: "Why? You really should. You're paying for these classes AND you really need to actually learn this stuff."

Son: "Well, because I got 100% on my last assignment without going to class. I just Google'd everything and figured it out on my own from what I found."

My wife out of the blue: "DAMN IT, BUT THAT'S NOT HOW IT WORKS IN THE REAL WORK WORLD!"

Oh, you poor, uninformed summer child. I love her, but she just doesn't know that my son has already learned the key lesson he needed to learn from his schooling in order to get a job and make good money in this field! #ProudTechieDadMoments

Boss: Who knows VB?
Me: I once wrote a calculator
Boss: Good enough! You will edit the companies biggest VB Application.

Lesson learned. When your Boss asks if you know a programming language you do not really know, you are like John Snow: Know nothing

Funny story about the first time two of my servers got hacked. The fun part is how I noticed it.
So I purchased two new vps's for proxy server goals and thought like 'I can setup fail2ban tomorrow, I'll be fine.'

Next day I wanted to install NginX so I ran the command and it said that port 80 was already in use!

I was sitting there like no that's not possible I didn't install any server software yet. So I thought 'this can't be possible' but I ran 'pidof apache2' just to confirm. It actually returned a PID! It was a barebones Debian install so I was sure it was not installed yet by ME. Checked the auth logs and noticed that an IP address had done a huge brute force attack and managed to gain root access. Simply reinstalled debian and I put fail2ban on it RIGHT AWAY.

Checked about two seconds later if anyone tried to login again (iptables -L and keep in mind that fail2ban's default config needs six failed attempts within I think five minutes to ban an ip) and I already saw that around 8-10 addresses were banned.

Was pretty shaken up but damn I learned my lesson!

I think I've shown in my past rants and comments that I'm pretty experienced. Looking back though, I was really fucking stupid. Since I haven't posted a rant yet on the weekly topics, I figure I would share this humbling little gem.

Way back in the ancient era known as 2009, I was working my first desk job as a "web designer". Apparently the owner of this company didn't know the difference between "designer", which I'm not, and "developer", which I am, nor the responsibilities of each role.

It was a shitty job paying $12/hour. It was such a nightmare to work at. I guess the silver lining is that this company now no longer exists as it was because of my mistake, but it was definitely a learning experience I hold in high regard even today. Okay, enough filler...

I was told to wipe the Dev server in order to start fresh and set up an entirely new distro of Linux. I was to swap out the drives with whatever was available from the non-production machines, set up the RAID 5 array and route it through the router and firewall, as we needed to bring this Dev server online to allow clients to monitor the work. I had no idea what any of this meant, but I was expected to learn it that day because the next day I would be commencing with the task.

Astonishingly, I managed to set up the server and everything worked great! I got a pat on the back and the boss offered me a 4 day weekend with pay to get some R&R. I decided to take the time to go camping. I let him know I would be out of town and possibly unreachable because of cell service, to which he said no problem.

Tuesday afternoon I walked into work and noticed two of the field techs messing with the Dev server I built. One was holding a drive while the other was holding a clipboard. I was immediately called into the boss's office.

He told me the drives on the production server failed during the weekend, resulting in the loss of the data. He then asked me where I got the drives from for the Dev server upgrade. I told him that they came from one of the inactive systems on the shelf. What he told me next through the deafening screams rendered me speechless.

I had gutted the drives from our backup server that was just set up the week prior. Every Friday at midnight, it would turn on through a remote power switch on a schedule, then the system would boot and proceed to copy over the production server's files into an archive for that night and shutdown when it completed. Well, that last Friday night/Saturday morning, the machine kicked on, but guess what didn't happen? The files weren't copied. Not only were they not copied, but the existing files that got backed up previously we're gone. Why? Because I wiped those drives when I put them into the Dev server.

I would up quitting because the conversation was very hostile and I couldn't deal with it. The next week, I was served with a suit for damages to this company. Long story short, the employer was found in the wrong from emails I saved of him giving me the task and not once stating that machine was excluded in the inactive machines I could salvage drives from. The company sued me because they were being sued by a client, whose entire company presence was hosted by us and we lost the data. In total just shy of 1TB of data was lost, all because of my mistake. The company filed for bankruptcy as a result of the lawsuit against them and someone bought the company name and location, putting my boss and its employees out of a job.

If there's one lesson I have learned that I take with the utmost respect to even this day, it's this: Know your infrastructure front to back before you change it, especially when it comes to data.

At my previous job, the person in charge of the Phabricator server didn't have a backup system in place. I yelled at him until he implemented one.

He had the server perform backups to the same drive. I yelled at him again, to no avail.

Well, after awhile the hard drive started failing, and it would only boot intermittently. After a lot of effort, he was able to salvage part of the backup data, but no more, meaning we lost a lot of bug reports and feedback, and developer tickets. We were able recover all of the older lost tickets from a previous server, so overall the loss was pretty small.

But I think he learned his lesson.
He definitely learned to listen.

Spending 5 years at University with a friend....uh???

Let me explain...

I have a friend. A very good friend I can say. I know him since 18 years but I started being everyday with him at the beginning of my "University's journey".

And when I say everyday, I am not joking...every lesson, every exam, every project...

The problem is that he is one of the smartest person I have ever met in the "scientific field". So? He is also unable to say that he doesn't understand something. He is unable to say the he is wrong or to admit that someone else is better then him.

Let just say that he is not good in "relating to other people".

I am very smart too and suddenly he started to fail where instead i was doing good. Jealousy, anger. Every occasion to point out my errors. Every occasion to say to the others that I am stupid and he is smart.

But I know him and I am not like him. So I continued to stay with him, work with him and also going out with him. Because he is my friend.

And you know what? After 5 years he started to be more "human". I learned so much from him and he learned to be respectful and humble.

It was a very stressful period but thanks to that I know that I can be strong and work hard also when someone try to stop me. I am not afraid to say my opinion just because someone is yelling at me. And I know that I can go over stupid judgements and still work good as a team member.

That's it.

Be respectful. Be patient but defend your opinions. Trust yourself but listen and learn from everyone. And if sometime you fail, remember that it's normal. No one is perfect. No one can be perfect alone.

I hope that this rant can help someone else.

Good week to all of you.

Had to wake four people up at 2 am to fix a crashing service.

10/10 would deploy to production on Friday night again.

Second semester

Java - OOP Course

We had to write a game, an arkanoid clone

Neat shit

And a fun course, mad respect to the Prof.

BUT

Most students, including me had this ONE bug where the ball would randomly go out of the wall boundaries for no clear reason.

A month passed, sleepless nights, no traces.

Two months later. Same shit. Grades going down (HW grades) because it became more and more common, yet impossible to track down.

3 months later, we had to submit the HW for the last time which included features like custom level sets, custom blocks and custom layouts.

So before we submit the game for review, they had pre-defined level sets that we had to include for testing sake.

I loaded that.

The bug is back.

But

REPRODUCIBLE.

OMG.

So I started setting up breakpoints.

And guess what the issue was.

FLOATING FUCKING POINT NUMBERS

(Basically the calculations were not as expected)

Changing to Ints did it's job and the bug was officially terminated.

Most satisfying night yet.

Always check your float number calculations as it's never always what you expect.

Lesson learned, use Ints whenever possible.

Saying yes to people who want a website for $100.

I've learned my lesson, all brand new websites now start at $1000.

Lesson learned: Ask the company to see a sample of their code before accepting the position.

A few years ago:

In the process of transferring MySQL data to a new disk, I accidentally rm'ed the actual MySQL directory, instead of the symlink that I had previously set up for it.

My guts felt like dropping through to the floor.

In a panic, I asked my colleague: "What did those databases contain?"

C: "Raw data of load tests that were made last week."

Me: "Oh.. does that mean that they aren't needed anymore?"

C: "They already got the results, but might need to refer to the raw data later... why?"

Me: "Uh, I accidentally deleted all the MySQL files... I'm in Big Trouble, aren't I?"

C: "Hmm... with any luck, they might forget that the data even exists. I got your back on this one, just in case."

Luck was indeed on my side, as nobody ever asked about the data again.

Life lesson learned:

If your girlfriend asks you what SO means, it's "Significant Other",

NOT StackOverflow.

fellow from the team was asked to do the estimate by manager - he said 2 weeks

then manager asked what if we add one more developer - he said, again 2 weeks and maybe add day or two

I was asked same question without knowing that they already asked fellow from the team same question - I said around two weeks, maybe day or two more! XD

as manager was confused and not satisfied with the estimates, goes to our team leader with the same questions - team leader said - 2 and half weeks and if you add one more dev to it, 3 weeks minimum

we didn't know that all of us were asked as manager did that behind our backs, in the end manager learned lesson in greed as we got to stick to team leaders estimate!

also that was very rude of underestimating someone's ability, same manager did had personal bias and frequently mocked us, for example when we said that that we will implement ML for cropping images at the right place (ie. crop part of the image where the face is) on the backend. Response was something like: 'You guys will do the ML? Are you shitting me? You're not /insert FANG company/!'

best team win ever!

second best team win ever is when whole team left the company in matter of weeks

So yeah, the name change is done. Me making a joke out of being called a code slut clearly backfired and people just started calling me a slut or inferring I was a slut or something unsavory because of an online username. Lesson learned. A few lessons, in fact.

Anyway thanks for allowing the name change @dfox and @trogus. Now, back to ranting.

we had this guy once, who we gave access to our private repo. everything's all good until we noticed that our amazon bill was USD 8,000+!!! we found out that lots of servers got created and that's bec. this guy forked our private repo and his fork was a public one. our keys were still not in .env files and were part of the commit so some bot got hold of it and accessed our amazon account. we suspected that the servers were used for bitcoin mining. anyway guy was fired on the spot and we also learned our lesson to keep keys out of repos.

!rant source: LinkedIn;
Yesterday I met with a potential client who wanted a website. I gave him a quote of X. He said, do this work for X/2 as I have lots of projects and I can keep you engaged for months.

If it was 2 years ago, I'd have happily accepted his proposal. But in the past 2 years I have learned this lesson hard way. Don't work for clients who don't pay well, because when a developer is not paid enough, the quality of work degrades. Hence the portfolio is degraded and so the future projects are also of low budget.

And before you know it, you will be surrounded by low paying clients who see you as a Skilled Labour.

Today, I don't negotiate, not even a single dollar. To justify my cost I make sure that no stones are left unturned while delivery.

It's better to work for 10 hours a week for 40$/hr then to work 40 hours a week for 10$/hr.

I get a call: "Hey the site is down. Fix it!"
Worked on my workstation, not on my phone => DNS issue.

Local cache: "All OK"
ISP's DNS: "No record"
Google DNS: "Server error"
MXToolbox: "All OK"
CloudFlare DNS: "Domain? What domain?"

After a day of fucking around with configs and wanting to strangle the customer support guy, I just started pressing buttons, until suddenly, it worked. Turns out I'd accidentally enabled DNSSEC on a domain, that wasn't configured for it.

Lesson learned: There is no official DNS error code for "DNSSEC failed somewhere upstream". If you're lucky, you might get something useful out of the authoritative server, but apparently not on Mondays.

I still miss my college days. Our crappy IT Dept restricted internet usage on campus. Each student used to get 10 GB of internet data and they used Cyberoam for login (without HTTPS). 10 GB was so less (at least for me).

Now, thanks to CS50, I learned that HTTP was not secure and somehow you can access login credentials. I spent a night figuring things out and then bam!! Wireshark!!!!

I went to the Central Library and connected using Wireshark. Within a matter of minutes, I got more than 30 user ids and passwords. One of them belonged to a Professor. And guess what, it had unlimited data usage with multiple logins. I felt like I was a millionaire. On my farewell, I calculated how much data I used. It was in TBs.

Lesson: Always secure your URLs.

You know what I realized we should always say no for demo driven application development.

We should always ask for enough time do a proper development and if its not enough, shouldn’t write a single line.

Because once we deliver a working demo. Its release ready for them because its FUCKING WORKING..

And trying to explain why this is just a demo and cant be put to production is even bigger pain in the ass than saying no in the beginning.

LESSON LEARNED .

I was offered to work for a startup in August last year. It required building an online platform with video calling capabilities.
I told them it would be on learn and implement basis as I didn't know a lot of the web tech. Learnt all of it and kept implementing side by side.
I was promised a share in the company at formation, but wasn't given the same at the time of formation because of some issues in documents.
Yes, I did delay at times on the delivery date of features on the product. It was my first web app, with no prior experience. I did the entire stack myself from handling servers, domains to the entire front end. All of it was done alone by me.
Later, I also did install a proxy server to expand the platform to a forum on a new server.
And yesterday after a month of no communication from their side, I was told they are scraping the old site for a new one. As I had all the credentials of the servers except the domain registration control, they transferred the domain to a new registrar and pointed it to a new server. I have a last meeting with them. I have decided to never work with them and I know they aren't going to provide me my share as promised.
I'm still in the 3rd year of my college here in India. I flunked two subjects last semester, for the first time in my life. And for 8 months of work, this is the end result of it by being scammed. I love fitness, but my love for this is more and so I did leave all fitness activities for the time. All that work day and night got me nothing of what I expected.
Though, they don't have any of my code or credentials to the server or their user base, they got the new website up very fast.
I had no contract with them. Just did work on the basis of trust. A lesson learnt for sure.
Although, I did learn to create websites completely all alone and I can do that for anyone. I'm happy that I have those skills now.
Since, they are still in the start up phase and they don't have a lot of clients, I'm planning to partner with a trusted person and release my code with a different design and branding. The same idea basically. How does that sound to you guys?

I learned that:
. No matter what happens, never ignore your health for anybody or any reason.
. Never trust in business without a solid security.
. Web is fun.
. Self-learning is the best form of learning.
. Take business as business, don't let anyone cheat you.

Spent 4 hours today working on a monitor that wasn't working. someone had put by their garbage can in the rain. I dried it out for about 2 weeks before plugging it in. It turned on but when I plugged in the DVI, it did nothing.

Today, I pulled the ENTIRE thing apart because either I could find out what was wrong, or all is lost anyways. Who knows what the rain could do to it?

With no luck, I did a quick search online about the model and found that this one just had some defective firmware (Who knew monitors had filmware??) I installed it, ran it, it took about 20 seconds and it worked!

Lesson learned once again: google is your friend

Hesitated for a while before posting this, as I don't like to whine in public but this should be therapeutical

Beware, it's a #longread

Years ago, I thought about how cool it'd be to have conversation-based interactive fiction on my phone. I remember showing early prototypes to my ex in 2012. It took me over 2 years to build up the courage to make it my priority and to take time off. FictionBurgers.com was born.

A few weeks in, a friend of mine forwarded me a link to Lifeline. I was devastated. I literally spent 2 days cursing my past self for not making a move sooner.

I soldiered on, worked 7 months straight on it. Now the tech is 90-95% finished, content is maybe 60% finished and I just... gave up. Every other week now, similar projects are popping up. I'm under-staffed and under-financed compared to them. Beyond the entertainment space, "conversation-based" is hot stuff in 2016, and I still can't seem to know what to do with what I have.

I feel like I had this fantastic opportunity and squandered it, which makes me miserable.

Anyway, just so you get some cheese with my whine, here are a few lessons I learned the hard way:

Lesson #1 : Don't go it alone. I thought I could hack it, and for over 7 months, I did. But sooner or later, shit gets to you, it's just human. That's when you need someone; just so that their highs compensate your lows and vice versa. Most of the actual writing was done by a freelancer (and he did AMAZING WORK, especially considering that I couldn't pay him much) but it's not the same as a partner, who's invested same as you.

Lesson #1.5 : Complementary skills. Just like my fiction project failed because I was missing a writer partner, my fallback plan of getting into conversational tech hit the skids for lack of a bizdev partner. It's great to stick among devs when ranting, but you need to mingle with a variety of people. Some of them are actually ok, y'know :)

Lesson #2 : Lean Startup, MVP. Google those terms if you're not familiar with them. My mistake here (after MVPing the shit out of the tech) was to let my content goal run amok : what made my app superior to the competition (or so I reasoned) was that it would allow for conversations with multiple characters! So I started plotting a story... with 9 characters. Not 2 or 3. NINE FREAKING CHARACTERS! Branching conversations with 9 characters is the stuff of nightmare -- and is the main reason I gave up.

Lesson #3 : Know your reasons. I wasted some much time early on, zig-zaging between objectives:
"I'm just indulging myself"
"No, I really want it to be a project that pays off"
"Nah, it's just a learning opportunity"
"Damn, why is it bothering me so much that someone else is doing the same thing ?"
"Doesn't matter, I just mine finished"
"What a waste of time !!"
etc etc
And it's still a problem now that I'm trying to figure out what to do!

So anyway, that's my story, thanks for readin'
Check out chatty.im/player/sugar-wars if you want to test the most advance version.

Also, I've also tagged this #startupfail, if any of you fine people want to share the lessons you've dearly paid to learn!

Today I told my lead developer that I liked star wars episode 8.

I got grilled pretty hard.

Like, I can drop a db and the motherfucker ain't gon give a fuck. But God forbid a mofocka likes episode 8.

That is a big no no to him.

Manager had told me that I should keep that opinion of the movie to myself.

Lesson learned.

This one time I aliased a coworkers 'sudo' with 'sl' (sl shows a train running across the screen)

And then I removed him from the sudoers group and sudoers list.

I then magnified his screen 200%

Changed his background to a shitty narwhal.

And then full screened a terminal with the 'sl' train stuck in a while loop.

You can't control c out of the terminal.

He solved the first part really quickly, fixing the full screened terminal and exiting out of it, magnification and the background.

But took him 4 days to find that I had fucked up his sudo. Apparently, he didn't need to use sudo in those 4days. It wasn't until he mentioned it out of the blue.

How did he find out about it? He was running an important script that had sudo in it. When he ran the script a train would pop up and his script would terminate early.

He came to me and cursed me to Satan's anus. He then asked me to fix it, but then changed his mind and said that he'd do it himself. After a while he couldn't figure out what I had done.

I walked him through it. Told him that he had to go to his .bashrc file and remove the alias.

Later he comes back to me and curses me to the 12th circle of hell. He found that he was no longer a sudoer. At this point he gave me access to his computer and told me to reverse everything that I had done.
Added him back into the sudoers group and called it a day.

Lesson to be learned? Don't leave your machine unlocked.

Recruiter: are you interested in a client side java role?

Me: yes, here is my client side resume please submit me

Recruiter: sorry the hiring manager said they are looking for more of a back-end engineer

Me: you told me it was a client side role, please resubmit me with my back-end geared resume

Recruiter: yes that's correct, it's client side, we'll keep you in mind for the future but you should know there is a difference between mobile devs and web devs

Me: what you just said is not relevant to this conversation. I would be happy to discuss the diff between front-end and back-end, client vs server, etc.

Recruiter: I'm just relaying what the hiring manager is saying to me

Me: your [lack of] ability to relay technical information is quite apparent :/

*lesson learned*: interview recruiters before they start interviewing me

Unbelievable waste of time, how do these people even make a living? FML!

A recent project actually taught me how HORRIBLY STUPID it is to store large bodies of text in a SQL Server database. There were millions of records with pages of compressed text each.

More and more text records pile on every single day. Needless to say it was becoming super slow and backups were taking WAY too long.

After refactoring them out as compressed files to disk storage (I love you, micro-services) and dropping them completely from the database, the backup size went from 90gb to 3gb!

It's not every day you get to see a dramatic result like that from a refactor.

Lesson learned, and yes it was quite cool.

Ok so the ex boyfriend (let's call him Joe) of a friend of mine is a dumbass

He wanted to hack her phone, or whatever, so hired someone on telegram to do it. He asked her phone number and 200€.

After actually giving him the money this guy sent a ransom asking for 2k to not turn Joe in.

Joe learned a lesson.

At work for a bank, I changed the target SQL Server in my SSIS project and arbitrarily, all my custom-coded scripts were erased!!

I didn't take backups and I spent a week coding them! Fuuuuuuuuuckkkkk 😠

Ended up rewriting them.

I learned my lesson... 😥

Things I have learned:

-NEVER trust a group of people not to reply all to a large email
-NEVER trust a group of people not to reply to a group text

Screenshot is from yesterday, and violates my second lesson learned (Not my group text, not my fault)

Lesson learned from wk111:

We gotta get out of the fucking house more guys and girls!

Go code on a fucking beach or a park or something. Drink some beers and wine. Smoke a couple of joints with good friends.

Some years back I was working in a project that essentially dealt with all things related to foreigners and foreign affairs in Switzerland. You could manage entry visas, work permits, citizenship, international warrants, Interpol requests, etc.

One of the test managers (from client side - i.e. the government) was once manually "testing" and mixed up the production and test instance, to both of which he was logged in at the time.
The test case then ended up setting up an entry ban against himself, as he used his own name for testing...

Next time he returned from vacation the border control at the airport were like "Uhm, Sir, we can't let you into the country. Please come with us." :D :D

(He managed to clear that up in end, I dare say, though, that he learned his lesson.)

Just a quick lesson that I learned in my entrepreneurship career, "You want to go fast, go alone! You want to go far, go together 😍"

TL;DR: check polarity before plugging your DIY circuits into others!!!

*goes off to watch some Lucky Star and drink some booze*
*notices phone battery dying after 3rd pint*

But my charging cable that Huawei delivered with this thing is way too short... Well that ain't no problem, I can make one of my own 😎

But I'm tipsy.. sound I really enter the workbench in this state?

*goes off to build a charging cable anyway*
But what was USB-A male connector's polarity again? Oh, there's the fan's USB connector that I've made in the past. Let's check on that one. So, left is positive and right is negative?

*solders the wires on*
Snip, strip, stick, done! Well that was easy. I guess that all those failed soldering attempts and lost pads in the past as a means of training did pay off in the end!

*plugs phone into Raspberry Pi media center through new charging cable*

Strange sounds coming from the speakers.. well that's odd. Reverse polarity or maybe the Pi can't handle a 1A load from my phone?

*plugs phone into the 5V 5A charging hub that I've made earlier*
That oughta do.. current limits should be no more in that thing.

*charging hub makes high-pitch noise similar to the Pi speakers*
Definitely a reverse polarity, isn't it :') let's check on the Gargler...
Oh shit! It is a reverse polarity mistake!!! Should've checked this earlier >_<

*resolders wires properly*
Alright, finally done.. as I'm writing this post, my phone's charging from the Raspberry Pi through my fixed charging cable now...

Lesson learned. Always check on the internet what the pinout is before soldering anything, don't solder while tipsy, and be fucking grateful that this phone has reverse polarity protection in it.

Nexus 6P with all its shortcomings regarding power delivery and battery management, luckily it's got reverse voltage protection features built-in. Otherwise it might've costed me my phone. Always double-check before plugging anything into something else!!!

Boss: Can you modify the prototype, so that I can show it off to the customers who will visit?
Me: Sure, when do you need it?
Boss: In two hours.
Lesson learned: Always have a branch in your git with a working demo.

N e v e r, fucking e v e r chmod/ chown permissions recursive on the linux /etc folder❗

I did yesterday (, because I am fucking dumb and know little about linux systems) and got the result today. My whole mailserver wasn't working.
After fucking tons of googling and searching and log-digging I found that postfix and opendkim require specific permissions on their respective folders and files.

After changing a fucking amount of permissions on those fucking files the fucking mailserver worked and I can send and receive mails, now. 😤😤😤

What a torture. Lesson learned. Never will repeat this mistake.

FUCKING WAITING FOR PEOPLE FUCKED ME OVER AGAIN. WHO WOULD HAVE FUCKING GUESSED?!

I learned a valuable lesson today about the life of a manager. I’m not a manager, but I am a senior level dev.

Today I was told there wasn’t room on the new team for 1 person, and I had pick that last team member. I had to choose between a friend who really isn’t cut out to be a dev and a non friend who is a better dev.

I talked through my reasoning and ultimately chose to put the friends job in jeopardy. They told me that I had solid leadership traits for being able to separate my emotions from my decision making. But I felt like a piece of shit.

I cried back at my desk. The friend doesn’t know yet and I can’t tell them. Is this what execs feel when they have to let people go?

Fucking teammate who did not know how to read/write a simple class diagram.
We warned him that he have to study or we just kick his fucking ass out of the team.

He just did nothing. When we had meetings he just stayed at home pretending to have an heart issue needing surgery.
After just 2-3 days he was tagged on FB in a photo shooted a few days earlier where he was riding a bike for a competition.

He skipped another scheduled-a-fucking-week-before meeting saying that he was on a surprise trip, when I called him 5 minutes before meeting start.

In the end we just kick him out because he did nothing. He went to professor talking about some relationship problem in the team and asked him if he could continue the project by himself just forking the ours.

Professor said HELL NO SON OF A BITCH.

But our team learned a precious lesson : choose your team carefully.

You wanted to hear more about my "glorious" teacher. I deliver. So get a cup of tea, take a seat and prepare for insanity.
As I already told in a comment my programming teacher is one special snowflake who lives in his personal bubble. We have final exams in less than a month and he spents at least half a lesson talking about vanishing bees and missing plants from his garden. Other topics he likes to talk about (and tries to turn every freaking conversation into at least one of these):
1. Other students and their stupidity
2. Diesel scandal
3. His sick wife
4. "Why does noone read newspapers anymore?"
5. Why he can't teach Java but really really really wants to and everyone hates him and forces him to do C#.

Even if I try to interrupt him he'll go on until he thinks we gained some "common knowledge" - this is how he justifies these topics.

Everytime he introduced us to a new command he compared it to Java and sometimes he even falsely corrects code because he confuses them.
We are only 6 people including me (another story for another time) and he is not able to help everyone during a 90min lesson. He normally sticks with one person for at least one hour and just talks to them or even do their tasks. This is really annoying if you have a simple question. He won't answer you until he's finished whatever he's doing.

Most of the time he doesn't seem to understand what he's talking about/trying to teach us. He's muttering statements from our textbook to himself switching halfway through to another sentence while drawing not decipherable shit on the blackboard.

Another gem are his "guidelines" for classtests. We are allowed to use any command we know. Except the ones we learned not in class. And the ones he doesn't like. And the ones he doesn't want to exist. And of course not the ones which make you're life easier. So basically we are bound to use his favourite commands or we won't get a good grade. Example: use an array. List is not allowed. Never.
He has some weird fetish with arrays.

I once presented him perfectly fine code I wrote in my freetime and asked what some warnings meant. (Was because of different Visual studio versions as I learned later.) He scolded me for using things he didn't taught us yet and ranted about how I'm pressuring him into rushing these things now - I never wanted to show this to my classmates nor was this anything else than a project for fun and learning something new. (FYI the "new stuff" where classes and objects because i was tired of kilometers of spaghetti code). His rant went on a good 20minutes and - obviously - he didn't answer my question. I asked my fiance that evening and he explained it to me.
This should it be for this time. I'm sure I have more stories to tell for another time!
Thank you for reading. ^^

I've found and fixed any kind of "bad bug" I can think of over my career from allowing negative financial transfers to weird platform specific behaviour, here are a few of the more interesting ones that come to mind...

#1 - Most expensive lesson learned

Almost 10 years ago (while learning to code) I wrote a loyalty card system that ended up going national. Fast forward 2 years and by some miracle the system still worked and had services running on 500+ POS servers in large retail stores uploading thousands of transactions each second - due to this increased traffic to stay ahead of any trouble we decided to add a loadbalancer to our backend.

This was simply a matter of re-assigning the IP and would cause 10-15 minutes of downtime (for the first time ever), we made the switch and everything seemed perfect. Too perfect...

After 10 minutes every phone in the office started going beserk - calls where coming in about store servers irreparably crashing all over the country taking all the tills offline and forcing them to close doors midday. It was bad and we couldn't conceive how it could possibly be us or our software to blame.

Turns out we made the local service write any web service errors to a log file upon failure for debugging purposes before retrying - a perfectly sensible thing to do if I hadn't forgotten to check the size of or clear the log file. In about 15 minutes of downtime each stores error log proceeded to grow and consume every available byte of HD space before crashing windows.

#2 - Hardest to find

This was a true "Nessie" bug.. We had a single codebase powering a few hundred sites. Every now and then at some point the web server would spontaneously die and vommit a bunch of sql statements and sensitive data back to the user causing huge concern but I could never remotely replicate the behaviour - until 4 years later it happened to one of our support staff and I could pull out their network & session info.

Turns out years back when the server was first setup each domain was added as an individual "Site" on IIS but shared the same root directory and hence the same session path. It would have remained unnoticed if we had not grown but as our traffic increased ever so often 2 users of different sites would end up sharing a session id causing the server to promptly implode on itself.

#3 - Most elegant fix

Same bastard IIS server as #2. Codebase was the most unsecure unstable travesty I've ever worked with - sql injection vuns in EVERY URL, sql statements stored in COOKIES... this thing was irreparably fucked up but had to stay online until it could be replaced. Basically every other day it got hit by bots ended up sending bluepill spam or mining shitcoin and I would simply delete the instance and recreate it in a semi un-compromised state which was an acceptable solution for the business for uptime... until we we're DDOS'ed for 5 days straight.

My hands were tied and there was no way to mitigate it except for stopping individual sites as they came under attack and starting them after it subsided... (for some reason they seemed to be targeting by domain instead of ip). After 3 days of doing this manually I was given the go ahead to use any resources necessary to make it stop and especially since it was IIS6 I had no fucking clue where to start.

So I stuck to what I knew and deployed a $5 vm running an Nginx reverse proxy with heavy caching and rate limiting linked to a custom fail2ban plugin in in front of the insecure server. The attacks died instantly, the server sped up 10x and was never compromised by bots again (presumably since they got back a linux user agent). To this day I marvel at this miracle $5 fix.

I just had my worst hackathon so far and need to puke my whole toxic hatred, the rant will be full of hate so be warned. (I just don't want to let it go on my girlfriend, but I need to shout it out loud somewhere)

First of all, it is alright to be a beginner at a hackathon. It is also alright to not know that much about coding and want to learn. But it is not alright to lie about your skill, pretend to be a senior programmer and waste my fucking time.

Don't even fucking dare to say your are "fit" in Android development if you just have done some foobar tutorial on YouTube, don't even bother to read the document and have literally non existent knowledge about computer science.

Why the fucking hell do you need to pretend to be a seasoned programmer if you are just a bloody beginner? I mean you are in a hackathon full of computer nerds so soon or later your impostor ass will be debunked so what is the point?

And the other guy. Why the fucking hell did.'t you say that you just begin Python for 3 months? You are not a fucking developer if you just started coding for 3 fucking months. Learn some fucking coding before starting with machine learning you fucking punk ass bitch script kiddie.

Alright, maybe I was too naive to not check my teammates' background before make a team with them. Fuck me and my fucking stupid ass. My dumb ass monkey brain fell for big mouths, I deserved the headache right now and none less.

Lesson learned!

This is something that happened 2 years ago.

1st year at uni, comp sci.

Already got project to make some app for the univ that runs in android, along with the server

I thought, omg, this is awesome! First year and already got something to offer for the university 😅
(it's a new university, at the time I was the 2nd batch)

Team of 12, we know our stuffs, from the programming POV, at least, but we know nothing about dealing with client.

We got a decent pay, we got our computers upgraded for free, and we even got phones of different screen sizes to test out our apps on.

No user requirement, just 2-3 meetings. We were very naive back then.

2 weeks into development, Project manager issues requirement changes

we have a meeting again, discussing the important detail regarding the business model. Apparently even the univ side hadn't figure it out.

1 month in the development, the project manager left to middle east to pursue doctoral degree

we were left with "just do what you want, as long as it works"

Our projects are due to be done in 3 months. We had issues with the payment, we don't get paid until after everything's done. Yet the worse thing is, we complied.

Month 3, turns out we need to present our app to some other guy in the management who apparently owns all the money. He's pleased, but yet, issued some more changes. We didn't even know that we needed to make dashboard at that time.

The project was extended by one month. We did all the things required, but only got the payment for 3 months.

Couldn't really ask for the payment of the fourth month since apparently now the univ is having some 'financial issues'.

And above all: Our program weren't even tested, let alone being used, since they haven't even 'upgraded' the university such that people would need to use our program as previously planned.

Well, there's nothing to be done right now, but at least I've learned some REALLY valuable lesson:

1. User Requirement is a MUST! Have them sign it afterwards, and never do any work until then. This way, change of requirements could be rejected, or at least postponed

2. Code convention is a MUST! We have our code, in the end, written in English and Indonesian, which causes confusion. Furthermore, some settle to underscore when naming things, while other chooses camel case.

3. Don't give everyone write access to repository. Have them pull their own, and make PR later on. At least this way, they are forced to fix their changes when it doesn't meet the code convention.

4. Yell at EVERYONE who use cryptic git commit message. Some of my team uses JUST EMOTICONS for the commit message. At this point, even "fixes stuffs" sound better.

Well, that's for my rant. Thanks for reading through it. I wish some of you could actually benefit from it, especially if you're about to take on your first project.

Yesterday I spent some time on the meta site for dba.stackexchange.com and found this one guy with 1 rep raging about how his questions aren't getting answered and how is answers are the best etc...

"I have 17 years of experience as a dba, blah, blah, blah, my answers are correct, blah, blah"

He got pretty destroyed by the mods and other users about how shit his answers were and how they weren't factually correct etc...

This just continues to show that no matter how much experience you have you won't always be right.

Same goes for my senior at work, he has 10 years more experience than me (I have 2) and he still asks for my point of view and help without being a dick about it.

I hope we'll all keep being nice people unlike that Stackexchange guy...

#1 life lesson I learned from coding?

Maybe not coding specifically, but I learned the difference between problem solving and solution finding.
Its helped me in a lot of areas of my life. Made friends and made enemies.

Today I learned the hard way that losing your app's key store means no more updating , bug fixing , performance boosting , features adding ...
The app had like 5k downloads on the play store ..
Lost the key when one of my hard drives burned ..
Lesson of the day : keep your keys safe .
*trying to stay strong*

Today I learned a lesson from corporate survival 101.

The difference between get it done vs get it right.

Boss, manager always want to get it done, while developers always want to get it right, most of the time. If you don't listen to your boss, manager and insist get it right, will eventually cost your job. I saw many get it done code, either the dev moves to another team or already left. They avoid their own code forever.

Perhaps be a good student, not the smart student is a good way to survive. Thought????

I need to make a confession about my terribly unprofessional project I made. Around two years ago I got thrown for the first time into back end development - I had to work on the project alone. As a very smart man I basically exposed our SMTP server as a nice and very flexible API.

Fortunately it was, by the design, a very short-lived project, taken down from the web completely and for good after around 2 months. I'm still happy I had more luck than brains and nobody used our server as a spam sending service in our name and I have learned a valuable and relatively cheap lesson in security this way.

Lesson Learned

Using a copyrighted image on a website not knowing it was copyrighted. That was stupid and humbling. So caught up in the roots lost sight of the leaves.

Lesson learned: Assume nothing, question everything.

Men. Live with it.

(Stupid mistakes that kept me from sleeping.. 🤦🏻‍♂️ Lesson learned: Sleep.)

Sometimes I am so motivated .Today I tried coding in car .(I was in backseat)
20 min: Damn,my eyes hurt😞
40 min: Why do I feel dizzy😵
50 min : Oooh...I feel like puking.🤢
51 min : Dad......Stop the caaa....
Nothing I'm done
Lesson learned

This is a somewhat old story. I joined a project in making a 2.5d platformer in Unity. A couple months in, the project manager had decided that this game would have two sequels, an MMORPG, a live-action movie and a web series. He informed the whole team of this decision. One week later, every member of the dev team had left. This scope crept forth from the depths of hell and ruined a simple project. Lesson learned: Keep the scope small and don't bite over more than you can chew.

Edit: I know that you should dream big, but don't make 4 games, a web series and a movie simultaneously.

I'm coming off a lengthy staff augmentation assignment awful enough that I feel like I need to be rehabilitated to convince myself that I even want to be a software developer.

They needed someone who does .NET. It turns out what they meant was someone to copy and paste massive amounts of code that their EA calls a "framework." Just copy and paste this entire repo, make a whole ton of tweaks that for whatever reason never make their way back into the "template," and then make a few edits for some specific functionality. And then repeat. And repeat. Over a dozen times.

The code is unbelievable. Everything is stacked into giant classes that inherit from each other. There's no dependency inversion. The classes have default constructors with a comment "for unit testing" and then the "real" code uses a different one.

It's full of projects, classes, and methods with weird names that don't do anything. The class and method names sound like they mean something but don't. So after a dozen times I tried to refactor, and the EA threw a hissy fit. Deleting dead code, reducing three levels of inheritance to a simple class, and renaming stuff to indicate what it does are all violations of "standards." I had to go back to the template and start over.

This guy actually recorded a video of himself giving developers instructions on how to copy and paste his awful code.

Then he randomly invents new "standards." A class that reads messages from a queue and processes them shouldn't process them anymore. It should read them and put them in another queue, and then we add more complication by reading from that queue. The reason? We might want to use the original queue for something else one day. I'm pretty sure rewriting working code to meet requirements no one has is as close as you can get to the opposite of Agile.

I fixed some major bugs during my refactor, and missed one the second time after I started over. So stuff actually broke in production because I took points off the board and "fixed" what worked to add back in dead code, variables that aren't used, etc.

In the process, I asked the EA how he wanted me to do this stuff, because I know that he makes up "standards" on the fly and whatever I do may or may not be what he was imagining. We had a tight deadline and I didn't really have time to guess, read his mind, get it wrong, and start over. So we scheduled an hour for him to show me what he wanted.

He said it would take fifteen minutes. He used the first fifteen insisting that he would not explain what he wanted, and besides he didn't remember how all of the code he wrote worked anyway so I would just have to spend more time studying his masterpiece and stepping through it in the debugger.

Being accountable to my team, I insisted that we needed to spend the scheduled hour on him actually explaining what he wanted. He started yelling and hung up. I had to explain to management that I could figure out how to make his "framework" work, but it would take longer and there was no guarantee that when it was done it would magically converge on whatever he was imagining. We totally blew that deadline.

When the .NET work was done, I got sucked into another part of the same project where they were writing massive 500 line SQL stored procedures that no one could understand. They would write a dozen before sending any to QA, then find out that there was a scenario or two not accounted for, and rewrite them all. And repeat. And repeat. Eventually it consisted of, one again, copying and pasting existing procedures into new ones.

At one point one dev asked me to help him test his procedure. I said sure, tell me the scenarios for which I needed to test. He didn't know. My question was the equivalent of asking, "Tell me what you think your code does," and he couldn't answer it. If the guy who wrote it doesn't know what it does right after he wrote it and you certainly can't tell by reading it, and there's dozens of these procedures, all the same but slightly different, how is anyone ever going to read them in a month or a year? What happens when someone needs to change them? What happens when someone finds another defect, and there are going to be a ton of them?

It's a nightmare. Why interview me with all sorts of questions about my dev skills if the plan is to have me copy and paste stuff and carefully avoid applying anything that I know?

The people are all nice except for their evil XEB (Xenophobe Expert Beginner) EA who has no business writing a line of code, ever, and certainly shouldn't be reviewing it.

I've tried to keep my sanity by answering stackoverflow questions once in a while and sometimes turning evil things I was forced to do into constructive blog posts to which I cannot link to preserve my anonymity. I feel like I've taken a six-month detour from software development to shovel crap. Never again. Lesson learned. Next time they're not interviewing me. I'm interviewing them. I'm a professional.

I think my server got hacked, yesterday I made a new server on scaleway for the sake of testing I made a user called dev, with password dev. Forgot to change password before I went to bed.

Logged in today to find that load is 5x.x and this (image) in my crontab

Note to self: You are a disgrace, who the hell uses 'dev' as password for ssh on port 22 -_-

Pro tip:

Make sure you can RECOVER from your backups.

It's all well and good backing this and that up, but make sure that when the shit really hits the fan you can recover.

I've now 4 days into recovering a raspberry pi that ran:
Pi-hole
Snort
DHCP
VSFTP
Logwatch
Splunk forwarder
Grafana

And serveral other things... I've learnt my lesson

Greatest lesson I learned from myself. Work for yourself. Create your own business while you are working. Be your own boss. Don't rely in employment alone.

I got laid off today. My boss business is a digital agency. Our client stopped working with several agencies including us because of an order from their mother company to only use 1 agency. My boss has no choice but to let me go.

Even if you got the skills and you're doing good in your work, these things can happen. It is beyond our control. I like my company and my boss but reality hits hard. I thought I will be with this company for a very very long time. I want to settle here and build my business but still work together with my boss. I have so many plans that instantly disappeared.

Oh well just be strong and move on. Happy job hunting to me again. Maybe this is God's plan to teach me some things. For me to create my own business seriously while working.

Mining-Noob-Exp. #1

Just received some ordered ASIC miner from Bitmain. I'm very excited wether I'll reach the ROI or just bought some expensive heaters.

Lesson learned: Don't forget about possible (high) import taxes and fees in your calculations. 😐

Time to piss of my landlord who is paying the electricity bill. 👺

I have been creating mods for Skyrim and Fallout for a few years now. One day another modder wanted to make his own game using Unreal Engine 4. I wanted to learn UE4 anyway and the other members have made many mods before, so I joined in.

Well, it turned out I was the only one with a professional programming background (this is where I should have run). The others were all modders who somehow got their shit working. "It works, so it's good enough right?" On top of that UE4 has a visual scripting system called Blueprint. Instead of writing code you connect function blocks with execution lines. Needles to say that spaghetti code gets a whole new meening.

There was no issue board, no concept, no plan what the game should look like. Everyone was just doing whatever he wants and adding tons of gameplay mechanics. Gameplay mechanics that I had to redo because they where not reusable, not maintainable or/and poorly performing.

Coming from a modding background, they wanted to make the game moddable. This was the #1 priority. The game can only load "cooked" assets when it got packaged. So to make modding possible, we needed to include the unpacked project files in the download. This made the download size grow to 20+ GB. 20 GB for a fucking sidescroller. Now, 1 year after release we have one mod online: Our own test mod.

Well we "finished" the game eventually and it got released on Steam. A 20 GB sidescroller for $6.99. It's more like a $2.99 game in my opinion. But instead of lowering the price they increased it to $9.99, because we have spent so much time creating the game. Since that we selled less than 5 more copies. And now they want to make it work on mobile. Guess who will definetly NOT help them.

I have spent ~6 month of my freetime for this project, my rev share is < 100€ and they got me a lot of headaches with all their dumb decisions. Lesson learned. But hey, I am pretty good with UE4 now.

Fucking brilliant. Paused my Ubuntu VM in VMWare. Unpaused it, the whole file system is corrupted.

There goes my 2 hours of customization. Lesson learned.

I should just quit. I am not paid enough to deal with this pissing contest.
Reviewer:
Need to add instructions (on readme) for installing pnmp, or if possible, have the top-level npm i install it (lol).
Also, it looks like we are no longer using lerna? If that's right, let's remove the dependency; its dependencies give some security audit messages at install.
Me:
it's good enough for now. Added a new ticket to resolve package manager confusions. (Migrate to pnpm workspaces)
Reviewer:
I will probably be responsible for automating deployment of this (I deployed the webapp on cloudflare pages and there is no work that needs to be done. "automating deployment" literally means replacing npm with pnpm). I disagree that it's good enough for now.

Imagine all readmes on github document how to install yarn/pnpm.

Lesson learned:
If you think an OOP static site developer can't handle modern JS framework, you are probably right.

Today I experienced cruelty of C and mercy of Sublime and SublimeLinter.

So yesterday I was programming late at night for my uni homework in C. So I had this struct:

typedef struct {
int borrowed;
int user_id;
int book_id;
unsigned long long date;
} entry;

and I created an array of this entry like this:

entry *arr = (entry*) malloc (sizeof(arr) * n);

and my program compiled. But at the output, there was something strange...

There were some weird hexadecimal characters at the beginning but then there was normal output. So late at night, I thought that something is wrong with printf statement and I went googling... and after 2 hours I didn't found anything. In this 2 hours, I also tried to change scanf statement if maybe I was reading the wrong way. But nothing worked. But then I tried to type input in the console (before I was reading from a file and saving output in a file). And it outputted right answer!!! AT THAT POINT I WAS DONE!!! I SAID FUCK THIS SHIT I AM GOING TO SLEEP.

So this morning I continued to work on homework and tried on my other computer with other distro to see if there is the same problem. And it was..

So then I noticed that my sublime lint has some interesting warning in this line
entry *arr = (entry*) malloc (sizeof(arr) * n);
Before I thought that is just some random indentation or something but then I saw a message: Size of pointer 'arr' is used instead of its data.

AND IT STRUCT ME LIKE LIGHTNING.

I just changed this line to this:
entry *arr = (entry*) malloc (sizeof(entry) * n);

And It all worked fine. At that moment I was so happy and so angry at myself.

Lesson learned for next time: Don't program late at night especially in C and check SublimeLInter messages.

I used to think I was so clever by viewing the source code of websites, and would just scroll through it for fun, but what really got me started in programming was the TI-83 calculator I got in grade 10.

You couldn't view the code of most programs on that calc without a computer connection, but I managed to get my hands on the source code of something simple and learned how to prompt for values and calculate things with them. Before I knew it, I was making little programs in BASIC that did formulas for me (Area/circumference of a circle, etc.). One of my professors caught me showing my calculator to another student in class, and assumed I was being a bad student. When I said I made a program as a shortcut for one of the formulas we were learning, she tried to call my bluff and said to write the whole program on the whiteboard for the class to see. 10 minutes of writing and more than one blank stare from my classmates later, the teacher just waved me off and continued the lesson. I was chuffed :-). I made these simple programs for all my math classes throughout high school.

Unfortunately, my first year of university I took a CS course, and my teacher was probably the worst I've ever had in my life. I decided it wasn't for me, and though I did maintain my general aptitude for tech (and was still the person who fixed everyone's printers and viruses), I took a different path, eventually getting an Arts degree in Anthropology.

Where I live, the market for this is more than stale. In fact, it's completely flat, so I thought I would take a course about programming with Arduinos for fun and see if I should return to school for a different certification. It was AWESOME! I made a wireless weather station with Xbees and sensors and built my own anemometer.

I got a job at a manufacturing company, and had the fortune to build a robot which eventually made it's way to the second season of Battlebots. The level of intelligence and enthusiasm I encountered really inspired me, and now here I am at 31, halfway through a BSc in Computer Science and working for a company that makes 3D printers.

It's been a long journey, but the adventure always starts anew tomorrow.

So I read this morning about some web teacher. Here is my story:
In high school I had a teacher who was "THE GOTO WEB GUY", at least that was what other theachers thought. Here is what reallity looked liked in a lesson of his:
He comes up with some ancient example he just found on some tutorials page and he just remembered bits of how to do it. So when he got stuck he fired up a google search. When a student had a question he fired up a google search. Because he didn't know shit. Of course you cannot know everything but he was so cocky about his skills that it really annoyed me. Best part? He sold web sites (joomla) where his greates achievment was to change the color of the template. Everything he teached in that semester had I already learned through selfteaching and tutorials in an evening.

nice, 10k reached before sidtheitclown! (that’s all that actually matters, heh)

so, yes, as promised it’s me… chris from chris’ full stack blog.

I think kiki knew this, as I used to be called fullstackchris… though very briefly... don't know why i was ever worried about the old clowns i used to work for knowing my identity here

i’m a host of react round up, and also an ex-futures trader (that life is / was hidden on Twitter), I’ve recently quit because I’m ALSO still building 4ish SaaS products including The Wheel Screener (wheelscreener.com) and CodeVideo (codevideo.io), over my LLC, Full Stack Craft (fullstackcraft.com)

oh yeah, and on top of that i have a full time job in Switzerland (read: not poor boi 38 or 40 hour work week, 42 minimum)

so yeah, its a fucking lot of shit to do and sometimes it’s too much! glad i have this place to vent

so, don’t be too harsh on me… really, 99% of my bitterness comes from the approximate 5 years of my working life (2018-2023) were taken from me by lying business folk type who actually didn’t know what the FUCK they were doing or talking about, even after promising me they did (at two different companies). Listen, I’m all for people telling me iTs a RiSkY VeNTuRe; i get it. But if you say everything is rock solid (like funding, my future employment, etc.) and it is not, then fuck you; you’re just lying to my face, it has nothing to with management vs employee, engineer vs. non-technical - you’re literally just a *bad person* (sorry, mechanical engineering genes and honesty to the core - sue me) To be sure, I was partially at fault - too optimistic, and too gullible, and I’ve have since learned my lesson. but still working on it. (obviously)

but things are look up - my company is running better than ever, the current job is great with insanely smart people

In the end, it’s always the hardcore engineers who are the most honest, hardworking, respectful, and the best to work with - you people know who you are…

Until then… see you in the next rant!!!! 🤬🤬🤬🤬🤬

Dutifully signed,

New job surprise: I will inherit a 900k lines of php code from a contractor dev shop. It is the company erp web app.
It has no version control, tests, architecture or configuration management of any kind.
There are just 1800 bug ridden files with almost no comments in a directory with lots of code duplication.
Also just learned that the contractor was paid a lot monthly for over 2 years for this monster.

I will need a raise quickly. At least management understands that I will need a couple of months to get a semblance of order in this madness.

And to you contractor I have your address and i'll try to restraint myself from vandalizing your house but I can't make any promises.

And fellow developers send help or beers or come and join me to teach this bastard a lesson.

#1 life lesson learned from coding:
Don't work on projects for the government or any authority EVER!

So I left this company I was working for for about 6 years and then eventually came back earlier this year. It was basically 2 backend devs, 2 frontend, and a designer, with me being one of the frontend devs, and the other operating as the owner/alpha of the group. And our coding styles couldn’t have been more different. I wrote code with purpose that could scale, while he wrote garbage that I affectionally labelled "brute force code"; meaning it eventually got the job done, but was always a complete nightmare to work with. Think the windiest piece of shit you’ve ever seen and then times it by 10. Edit the simplest thing at your peril. And if you think you fixed something, all you’ve ever really done is create another 10 problems. And because the code was such shit, it relied on certain things to be broken in order for other things to work. Anyway, you get the drift.

In the beginning we used jQuery and so we just continued to use it throughout the years. But then when I finally left I realized we were operating in a bit of a bubble, where we didn’t really care much to ever try anything else, and mostly because we were arrogant. But eventually my boss started to notice the trend of moving away from jQuery, so he converted everything to vanilla JavaScript. Thing is, he hadn’t learned ES6 yet or any of the other tools that came along with it. And so it was a mess, and I was quite shocked at how many lengths he’d gone to create the full conversion. Granted, it was faster. But overall, still a nightmare to work with, as the files were still thousands of lines long. And when I dug deeper, I realized that he’d started to pluck things out of the DOM manually on-demand. And so it dawned on me: he’d been looking at sites built with React and other dif-engines, and then instead of just using one, he decided to reinvent the wheel. And the funny thing is, he thought it was just a matter of always replacing the entire HTML for whatever was needed. And so he thought what he was doing was somehow clever. And why not? He’s a badass mathematician who created an empire with jQuery. And so he obviously didn’t need input from anyone, and especially not from the shitty devs over there at Facebook. Anyway, while I was gone I learned quite a bit of React, and so it was just comical to me when I came back and saw this. Because it would have been a million times more efficient had he just used the proper tool. In short, he’d re-written the entire codebase for two full years and then ended up with another round of brute-force garbage.

So that’s my story. The lesson is, when you work for someone who’s a dumbass piece of shit, sometimes he’ll be so stupid the only recourse is uncontrollable laughter. I became a digital nomad somewhere in between and fucked off to Asia where I barely worked for 2 years. And I’d definitely recommend the same for anyone else with an asshole boss where the work is unfulfilling. Because it doesn’t matter what your job is when you’re living like a millionaire in Asia working 15 hours a week.

Who am I?

Some of you, because of the hyperbolic, outrageous, trollish, and often self-satirical nature of my posts, might doubt me. Thats completely relatable.

Heres the truth:
I was diagnosed in childhood with ADHD, fucking everyone, every male, these days is diagnosed with that. I was diagnosed bipolar. Hell anyone reading my posts could see that from a mile away. I was diagnosed on the borderline personality spectrum. Yeah, I could see that.

I was tested. They said I was in the 98th percentile for clerical ability, not extraordinary but pretty good, mathematical ability a little higher than that. My SAT was 1491. Not yale material, but I coulda been someone.

Over the years I studied a LOT of politics and read a metric fuckton of books. (40+ books over the course of three years).

I predicted every single presidential election since bush juniors second election. Three supreme court picks. Senatorial elections. Congresional elections. More than that.

I have a better analysis track record than some of the multidecade analysts sitting in the fucking NSA.

No I am not shitting you. No I am not exaggerating.

It's about the only claim to fame I get to legitimately make.

People ask me, "then why aren't you famous?"

How do you know I'm not.

Look I'm gonna tell you my actual name.
My real name is Lawrence B. Lindsey

Okay, I'm bullshitting for fun. But words I have written on alt twitter accounts have legitimately come out of presidential hopeful's mouths. No, this I am *not* bullshitting you about.

Imagine that. A guy who lived in his parents attic for five years, writing words that came out of presidential candidates mouths.

At one time I was about as popular and influential as that fuckboy catturd.

yes, really. No I am not fucking joking.

Under normal conditions I wouldn't talk about this or reveal it, because who the fuck cares? I'm just some dude on the internet, drunk, both on alcohol, and the pseudo-anonymous equivalent of bragging rights.

You know how many women I turned down because I could? You know how fucking drunk I am? They say a drunk man's words are a sober man's thoughts. Well, I'm not usually honest like this because the internet is full of false braggarts, and you tell people the truth and they don't fucking believe you.

I swear, it seems like I made some faustian bargain at some time, and can achieve no fame or lasting wealth in my life--to save my life.

Shit, I was talking to a chinese women who ran a bank in china (yes, really), who advised me to buy into bitcoin early on. Didn't have the money to. Woulda been a fucking millionaire if I did.
*Non-obvious* Ideas that major corporations are now persuing? Yeah those were sitting in my card index since the early 2000s.

I helped two people build and sell businesses. One for me tens of thousands. Another for millions. Yes, really. Got zero, and I mean, *zero* credit for it.

Point is, doesn't matter how famous you are, or coulda been, Doesn't matter the ideas you have, or had.

The world doesn't promote runners-up, or hasbeens, or wannabes, or could-bes.

What matters is execution.

If you're wandering through life, wondering when you're lucky break will be, stop. You have to realize, you make your own luck. Recognize the difference between what you can control, and what you can, and work on promoting your own ideas or business or values, instead of other people's dreams.

And for those wondering, yes I am drunk, and no, I ain't fucking kidding you in anything I wrote here.

The most important lesson I learned is this:
First work on your own success, before you work on the success of others.

p.s.

I give surprisingly good advice for someone who doesn't benchmark well on traditional measures of success. I know, even I was shocked when I looked at the statistics.

A child's mind is fascinating.

I remember how it felt being a kid, just deliriously happy.

Things were magical, mystical and happy.

I knew the world wasn't perfect, I knew bad things happened to good people.

But a kid's mind is so powerful that it can fill in the blanks with the most cheerful and optimistic perspectives.

And at some point in my childhood I was exposed to videogames, and that kinda took me down fantasy lane even further.

I was extremely young and barely retaining any memories when I was exposed to my first console, a famicom.

I have a somewhat vivid memory of my mind being blown away for the first time by watching my brother play New Ghostbusters II for NES.

From then on, we never stopped and played several console and dos/pc games.

When I was 10, someone from the neighborhood brought in a couple of floppys with Pokemon Yellow.

"What? Pokemon? How the fuck is that even possible? This is a pc, not a gameboy".

I didn't know at the time what an emulator was, but I was super fucking stoked to be able to play that.

My dad had a 1 gb laptop from work that he didn't use, so I hoarded that shit, and I would get to bed and play nearly everyday.

The experience was surreal. I was doing pc gaming... not on a chair, on a fucking bed, and I was playing a gameboy game... on a pc.

It was so intense to me, that even after more than 2 decades of that time in my life, I still remember how it feels like.

Like, you know how you can "feel" things if you think about them? like for example if you think about the taste of chicken, you can somehow feel it for a second.

Well I have like an actual physical sensation linked to that experience but I can't explain it at all, because it's just a sensation.

I think people usually say they feel that way, for example, about the PSX (usually refered to as ps one) loading screen. I experienced that too but when I was 12, so it was not as intense (it does make me feel the fuzzies though).

I also remember other things with very high detail, like the texture of my bed cover, the weather, mom cooking, the clunky shape of the laptop, the way I carelessly stored it above a pile of magazines, etc.

I rememeber ofc how it felt looking at the game sprites, interacting with NPCs, and the goddamn fucking glorious music.

It was dreamy.

Years and years later, I grew up and I stopped living in fantasy world and became more aware of the grim aspects of life my younger self was sugarcoating.

So I tried to play pokemon again, again and again, and no matter how hard I tried to revive that euphoria, I could not never do it.

I started to get annoyed at the game.

"Come oooon, I did the tutorial already, let me skip this.
This pokemon is useless, why am I even training it.
Fuck, I'm tired of grinding"

At some point I accepted that the feeling would never return, and that it would just live in my memory.

Ironically, I can recall that memory and how it felt anytime I want to.

And I can actually still feel it, and throughtout these years, it has never wore down.

And eventually I learned how to play pokemon and enjoy it:

I read tier lists at smogon online and just catch and train the pokemons that are higher on the list, which is how i got to beat yellow in like 3 days.

(This is nothing compared to what speedrunners do, but much better than the weeks it had taken me in the past).

That served as an important lesson that when a kid plays a game, his mind is also the game at the same time, filling the blanks with its imagination.

A very similar experience happened to me with harvest moon, which is the precursor of stardew valley.

and that game is faaar more emotional: you talk to people, overtime you befriend them and they open up, you meet a girl, you marry her, have a kid

you get farm animals, you brush them, they become happy

you get attached

that game was also so powerful in me that in all naiveness I thought I wanted to be a farmer.

Eventually I grew up and hit puberty and from then on, I focused more on competitive games, like smash bros, cs and tf2.

and i dunno how to end a post so eat my fucking nuts

My computer science class in school is learning c# so slowly that last year it took 3 weeks for them to learn what an integer is.
I learned most of the language on a vacation last year and now I don't show up for class.
and actually, my teacher doesn't mind it, she encourages me about learning more and doing projects.
best teacher I've had so far.

recently the class teacher noticed me when I go home instead of going to class and he made me come to every lesson. Really frustrating.

For fuck sake Facebook test your shit before you update!
Lesson learned, never update Facebook pods ... or even better never use Faceshit!

This is a story of me trying out maintaining a game server and eventually making a mistake, although I do not regret experiencing it.

A month ago I set up a small modded minecraft server because I wanted to experience a fun modpack together with some people from reddit. Besides this, I also wanted to see if I was capable of setting up a server with systemd and screen running in the background. This went great and I learned a lot.

The very next day I was playing with $annoyingKid on the server and everything was well. However the second day, $annoyingKid started pushing the idea to start up a normal minecraft server to build a playerbase.

I asked $annoyingKid 'What about financing, staff management and marketing?'

$annoyingKid: "I don't know much about that, but you can do that while I build a spawn!"

He also didn't want to reveal his age, which alerted me that he's young and inexperienced. He also considered Discord 'scary' because there were haxors and they would get his location and kidnap him, or something. So if he was supposed to become owner (which he desired), he had no way of communicating with a community outside of the game.

He also considered himself owner, while I was the one who paid for the server. 'Owners should be people who own the server', no matter how many times I told him that.

$annoyingKid also asked if he could install plugins on his own, I asked him if he knew anything about ssh, wget or bash because I used ssh to set up the server (I know rcon exists, but didn't want to deal with that at the time), he had no idea what any of those terms meant and he couldn't give proper arguments as to why he should get console access.

In the end, he did jack shit, he had no chance of becoming co-owner or even head-admin because he had no sense of responsibility or hard work. I kept him around as an admin because he was the one who came up with the idea. I banned him on day one after he started abusing his power when someone tipped him of. Even after me ordering him to ignore an annoying player he kept going, of course I could have prevented all this by kicking him earlier since all the red flags around him had already formed a beacon of light. He tried coming back, complaining that he should at least have his moderator rank back, but he never got in again.

A week later I got bored, I had had enough fun with ssh and the server processes to know that I didn't want to continue the small project, so I shut it down and went on to do stuff on GitHub.

Lesson learned: Don't let annoying kids with no sense of responsibility talk you into doing things you aren't sure you want to be doing. And only give people power after they've proved to you that they are capable of handling it.

The biggest lesson I learned in Frontend Dev is: listen to users, not clients.

There are so many rants about stupid ass clients on here, and when you let clients treat you like that, it's kind of your own fault. Look at how people use your interfaces and you will immediately see what's bullshit about them. When you have user behavior as an argument basis, clients will listen to you.

Worst fight?

Stubborner against stubbornest.

About a focking fact that was trivially true or false. Fun fact: it didn't matter anyway.

Boy, did we raise our voices and attract the attention of everybody in the room. Lesson learned.

Lesson learned: if you're going to derive a class in c++, make sure to declare a virtual destructor on the base class!

I just fixed (one of...) the massive memory leaks in my damn project.

Pictured: the strings in a derived class actually getting freed!

My boss just called me and asked to write a email informing our clients to not to download the update we pushed this very evening because Application is crashing when you will open that particular page.

What went wrong? One of our senior Developer, let's call him Mr. X, is totally against of testing the app before deploying it to clients. He believes that as i have created the application, i know exactly what to change to accomplish a requested feature or bug in application.

When a ticket assigned to him about a bug in the application, he simply make some changes in code, create the package and send it to test department. How do I know? He even boast it in front of us.

Most of the time it works but not every time like today. And I am pretty sure my boss is not going to ask a explanation about this to him.

I have great respect for him. It's okay to have confidence but testing before sending it to anybody will not make you junior. Will it? Being a senior You are making others to be careless about his job.

That's what happen today. Mr. X failed so does the testing department. So am I. I am the head of testing department as well.

I am not blaming him. I just cant. It was our job to test app thoroughly. I am feeling pretty bad now. His confidence made me vulnerable. Say his confidence made me clearly a fool. Lesson has been learned though.

Once upon a time, an IT major named adamyeti thought it was a good idea to work on projects directly off of a flash drive with no backup. Halfway through a large ASP.NET project, the drive failed. I fumbled through a free drive recovery tool, but all of the data was scrambled and corrupted.

I ended up having to start from scratch on the project, but I learned my lesson for sure.

My cat decided to jump on the PC at 5 AM.

Lesson learned: Never going to put my PC on the desk again.

The company I work at sends their developers out to other companies to help them work on projects and help them in other ways (advice when communicating to customers of on demand software for example).

While not on a project you are working in house training trainees and interns. Part of that is teaching them to show initiative and treating them as full developers. The 30 interns all discussed a git flow and code format.
During the third sprint (two weeks sprints) a team messaged me if I wanted to check their merge request for the sprint.

It took me a glance at the first file to know they didnt do any review themselves. I used my flywheel to check all their changes and without being able to read the code I saw indentation was all over the place, inconsistent bracket placements etc. I let them know I wouldnt check their code until it was according to their own standards.
Two days later I got the message to check it again. At first glance the indentation was fine so I started reading the code. Every single thing was hardcoded, not made to support mobile (or any resolution other than 1920×1080).
A week later they improved it and still not good. Gave them a few pointers like I would for any colleague and off they went to fix things. The code became worse and indentation was all over the place.

I told them the next time it shouldnt be a quick glance to be able to reject it again. By this time other teams came to me asking why it wasnt merged yet and I explained it to them. One of the teams couldnt do anything u til this was merged so I told them to implement it themselves. I was surprised that 4 teams came to me asking about a merge request, that was every team except the team whose pull request it was.

4 weeks after the intitial sprint the other team made a merge request and I had three small comments and then an hour later it was merged.

The other team messaged me why their merge request did went through (still havent seen any of their team in person, Im sitting 10 meters away from them behind a wall)
They also said that it was easier for them because they started from scratch. Thats when I called them in to discuss it all and if they were not interns but full time developers they would have been fired. I told them communication is key and that if you dont understand something you come in person to ask about it. They all knew I like teaching and have the patience to explain a single thing ten times, but the initiative should be theirs.

One of the team members is my current coworker and he learned his lesson by that. The others stopped with their study and started doing something completely else.

TL;DR
Merge request is open for 4 weeks, in the end another team started from scratch and finished it within a week. The original team didnt ask me questions or come to me in person, where other teams did.

DISCLAIMER: some of you might find it harsh, but in our experience it works the best for teaching and we know when people don't dare to ask questions and we help them in that too. It's all about the soft skills at our company.

Never buy crappy, consumer-grade SSDs for use in production servers/RAIDs. This might sound obvious but at the company I used to work for, through a series of bad decisions by management and cheapness, we ended up with the cheapest consumer SSDs you can imagine powering all of our storage.

This turned into a nightmare spanning years of failed hard drives and a continues cycle of ridiculousness. Drive failed after a few days, gets taken out, sent back to manufacturer and then replaced with another equally crappy drive destined to fail within days/weeks.

Our ops people were going to the data center multiple times per week to replace failed drives. Lesson I learned: cheaping out on system-critical hardware and software can have long standing consequences and in the end usually doesn't end up actually saving money when you account for time employees have to spend dealing with issues that result from it.

A lesson I learned. Clients can't separate design from functionality. They will piss and main about a feature not working right when what they really mean is the aesthetic is not to their liking.

Lesson learned: never drink during programming

Make. Fucking. Backups...

I had to find a MailChimp sync plugin for a webshop and thought I found a good one that synced one way (webshop to MailChimp).

I figured, meh, what could go wrong? So I installed it, ran it...and somehow lost around 4000 mailinglist receipients because they were not in the webshop.

Turns out it adds the registered users in the webshop, but also removes entries that are not! Needless to say, I had some explaining to do and was only able to recover about 3000 addresses from a previously sent campaign.

Customer was not happy, neither was my boss, very important lesson learned...

Just spent an entire night eaning up my codebase...

I optimized some of the functions got rid of unnecessary global variables and changed up the whole file hirearchy so it would be easier to read. After spending all night doing this I went to run the program and for once it seemed everything worked right the first time! However a portion of my application that is supposed to happen at a certain date and time never would run. After spending all night comparing each and every line for what I changed versus my last commit I couldn't find the fallacy in my logic. Everything should still work like it did before. After spending more time looking for bugs I finally realized I didn't break anything when I switched over to this new structure it was the old code that was broken. I went through the old code and after some debugging eventually found the culprit an extra continue statement that prevented my loop from fully executing. Lesson learned sometimes the biggest bugs can spawn from one line of code.

I'm the kind of person that says "Fuck python, worst language, fuck C#, Java, Golang", assembly and C are superior.

But I have learned my lesson; Yesterday I learned enough C# to be able to make a windows app that connects to a another app via sockets. I tried first to do it with C++ but my app looked like shit and took me about a whole day to make. Then I tried with C#, got the App working on an hour, now I'm delighted with C#. I guess I have to be open-minded.

This is why you should make a knowledge database and never trust the internet to keep things

Two quality rants with a lot of useful information I favorited are missing, surely because their authors removed their account

Lesson learned. One more resolution to apply for 2021

No wonder my Python code was broken. I called the super function of the wrong ancestor 🙄 Lesson learned: run the tests after every functional change, no matter how trivial it might seem.

*knock knock*

Race condition!

Who's there ?

And thaaaat's the lesson i learned today after I spent two hours staring at code, to find out that the solution was just moving an unlock_mutex() a few lines down.

Lesson learned the hard way: Remember your SSH Ports or write them down...

On the bright side of things, i had backups this time! Tyy DigitalOcean :)

a lesson that I learned the hard way: Don't test a code or a library on your master branche, in other words: don't shit where you eat.

I have the same problem as @linuxxx does. Buying things when I really don't need to.

I went to a mall with a friend today because his headset was literally falling apart. We both bought new headsets. Great.

Lesson learned: Don't leave your house unless necessary.

Just had an interview, but since I am a smart ass I decide that half an hour notice before the interview is OK after working the whole day with queues, docker & php multithreading, so we start an interview over Skype and my persona was able to duck up how simple joins work as well as function which is supposed to return the sum of even numbers between 2 and provided argument... I was off by 2..

Lesson learned never get in an interview after a whole day of mindfuckery .. Never

Me : *testing json output on pc by sending items with GET*
App : *app crashing with only recyclerview error*
Me : *debugging the app for 2 hours and testing ways to do another adaptor *
Me : fuuuuuuuuuuuuuuuuu... I used POST to get the data on app and forgot to change $_GET $_POST
Lesson learned. Always check the input first
Im ashame of my self #crysinthecorner

<insert bear grylls meme>
Improvise. Adapt. Overcome.

Lesson learned: take measures before buying parts

Stupid fucking idiot startup asshole hired me as an intern. Promised me the money after the work is done. We were friendly during the internship. The work is done and now it's been a week and still no money yet. He's saying it'll take some time. To beat you to shit it'll take some time you asshole!

Lesson learned: Never ever be friendly with the guy who hires you. Like never!!

Also money later isn't a good thing.

I know most of you know this, but after having dealt with both recruiters and real companies I can safely say that recruiters are of no practical value.

I've wasted countless months of my life interacting with recruiters and getting nothing out of them. To me it seems they're only after fluffing their client base.
The only time I got a job was through the real companies themselves.

Now I have learned the lesson: stay away from recruiters.

I've always been kinda lazy about backups and such, thinking it wouldn't be so bad, and "I have my most important stuff on Dropbox".

Just now, for some reason one of my hard drives just stopped for a bit, and I couldn't do anything with it anymore. Luckily it went away after restarting my pc, but it scared the shit out of me, as I almost lost 500 gigs worth of music, films, documents, etc...

This made me really think about the whole backup thing, and I'm creating a disk image as I type this. The time that I spend on that will be much less then the time it'll cost to recover everything. Lesson learned ^^'

Lesson learned: never ask for VPN

Trying to resolve merge conflicts and you cant remember which changes are the ones you want to keep. Lesson learned, make sure your pull requests dont sit waiting for weeks while master is happily being worked on.

Lesson learned: Browsers won't not try to draw huge images. They'll just...

At the age of 10 I got interest in ''changing computer'' things. I started to watch over the shoulder (I don't know if you can say that in English ¯\_(ツ)_/¯ ) of my dad. He programmed I2C and other microcontroller.
I started with little batch files and Visual Basic. I think we all know the ''Virus'' with shutdown 😂
At school in the computer lesson we learned a few other languages. I was the only one who learned these languages at home too. The biggest problem is that you think ''I learn at school and at home I can play games''.
Some day I started to learn PHP and Java at home. I came to Java with Minecraft. Yes, Minecraft. You can learn so many things (like the structure of a network packages from the server) and you can visualize everything with blocks.
Since the professional colleague we learn C# and Python which I use in some projects at home too, for example for the rasperrypi.
Now I'm 17 and I can C#, Visual Basic, PHP, JS, Python, JS and HTML

sudo rm -rf *

Just started out on linux, learning the ins and outs. All I wanted to do was remove two directories. Thankfully it was a fresh install, didn't lose anything important.

A valuable lesson was learned that day. 😂

Dev lesson learned the hard way. Never rm -rf with wildcard arguments... If you think you're being clever it probably means you're about to mess up some shit.

I need to rant about life decisions, and choosing a dev career probably too early. Not extremely development related, but it's the life of a developer.

TL;DR: I tried a new thing and that thing is now my thing. The new thing is way more work than my old thing but way more rewarding & exciting. Try new things.

I taught myself to program when I was a kid (11 or 12 years old), and since then I have always been absolutely sure that I wanted to be a games programmer. I took classes in high school and college with that aim, and chose a games programming degree. Everything was so simple, nail the degree, get a job programming something, and take the first games job that I could and go from there.

I have always had random side hobbies that I liked to teach myself, just like programming. And in uni I decided that I wanted to learn another language (natural, not programming) because growing up in England meant that I only learned English and was rarely exposed to anything else. The idea of knowing another fascinated me.

So I dabbled in a few different languages, tried to find a culture that seemed to fit my style and attitude to life and others, and eventually found myself learning Korean. That quickly became something I was doing every single day, and I decided I needed to go to Korea and see what life there could be like.

I found out that my university offered a free summer school program for a couple of weeks, all I had to pay for was the flights. So a few months later I was there and it was literally the best thing I'd done in my life to that point. I'd found two things that made me feel even better than the idea of becoming the games programmer I'd always wanted to be. Travelling and using my other language to communicate with people that I couldn't in English. At that point I was still just a beginner, but even the simple conversations with people who couldn't speak English felt awesome.

So when I returned home, I found that that trip had completely thrown a spanner into my life plan. All I could think about after that was improving my language skills and going back there for as long as possible. Who knows what to do.

I did exactly that. I studied harder than I'd ever studied for anything and left the next year to go and study in Korea, now with intermediate language skills, everyday conversations no longer being a problem at all.

Now I live here, I will be here for the next year and I have to return to England for one year to finish my degree. Then instead of having my simple plan of becoming a developer, I can think of nothing I want to do less than just stay in England doing the same job every day, nothing to do with language. I need to be at least travelling to Korea, and using my language skills in at least some way.

The current WIP plan is to take intensive language classes here (from next week, every single weekday), build awesome dev side projects and contribute to open source stuff. Then try to build a life of freelance translation/interpreting/language teaching and software development (maybe here, maybe Korea).

So the point of this rant is that before, I had a solid plan. Now I am sat in my bed in Korea writing this, thinking about how I have almost no idea how I'm going to build the life that I want. And yet somehow, the uncertainty makes this so much more exciting and fulfilling. There's a lot more worrying, planning and deciding to do. But I think the fact that I completely changed my life goals just through a small decision one day to satisfy a curiosity is a huge life lesson for me. And maybe reading this will help other people decide to just try doing something different for once, and see if your life plan holds up.

If it does, never stop trying new things. If it doesn't (like mine), then you now know that you've found something that you love as much as or even more that your plan before. Something that you might have lived your whole life never finding.

I don't expect many people to read this all, but writing it here has been very cathartic for me, and it's still a rant because now I have so much more work and planning to do. But it's the good kind of work.

Things aren't so simple now, but they're way more worth it.

This temporary hack will just temporarily fix this problem. We will come back and actually fix the problem later.

We never come back to fix it later. This shitty hack I made in less than a day that fixed the problem for the day "fixed" the problem for the next year.

Lesson learned that temporary structures and side projects will be there forever. Make them right the first time.

Learned an important lesson today- Never be sentimental towards your code.
The only thing common in all clients is the habit of changing their requirements, how sure they are about the unsurity of what they want. And if you are sentimental towards the code you write, about a difficult algorithm you implemented you will be in a mess

Lesson Learned: Don't ever be so ambitious that you are no longer realistic about your abilities. I remember when I started out, I would give unbelievably short TTC estimates for medium/hard tasks that would undoubtedly take some time.

Newer Dev here. Just recently started in a position as a developer. I'm tasked with consolidating our monitoring systems into one cohesive display. After lumping together all the indexes and helping build a custom API I'm now working on front end. Front end is easy, I've done it before. Should be no problem. I was wrong. I spent a whole day fiddling with a React dynamic table and the CSS to format it. Today, I stumble upon the react-table component. Got the results I was looking for in less than 2 hours. I'm convinced that this was a lesson better learned early on.

I had my presentation early morning, it was 3am, and I was still up because the code was not compiling. Then showed up my roommate who had gone for party. Can't believe that he was the one, in the half drunk state, was able to find just a short typo,but not ME, EVEN THOUGH I HAD 3 CUPS OF COFFEE the same night. Lesson learned. Patience is a virtue. Blessed to have a nice roommate. :)
PS. It was a Matlab code for filtering the mentioned portion of an ECG Signal, and analysing the problem faced by the patient. Well, I was pretty sure to get arrhythmia if I couldn't complete the code by morning.

Older tech support story, but still a frusterating one.

Sister was running Windows 8.1 (ew) when Microsoft was ramming Windows 10 down everyone's throat.

Her laptop decided to update to Windows 10, and after waiting awhile, she decided to unplug the laptop's battery and power chord.

This did what you expected, corrupted her install, leading to a bootloop. I then got to deal with that to try and recover it.

Once I got into the recovery mode, it wanted her password to restore from a system image, guess what she forgot?

She tried her PIN, and gave up after a few attempts, and I got to reinstall Windows for her.

Lesson learned from this? If you're the IT person of the house, make sure that you have an account on all machines that you may administrate. That way you don't need to deal with this shit.

One crucial lesson I learned while diving into programming:

Use various learning resources. Everyone explains things a little different.

You can understand stuff much easier.

Very important lesson I learned while working with Xcode:
Always have multiple major versions installed and ready to be used.

Xcode 9 can't convert old Swift 2.2 project to Swift 4 and can't open the "old" project? Xcode 7 can help you.

Xcode 9 crashes randomly while moving top level packages? Xcode 8 can help you.

Yeah, always funny to find new bugs in Xcode...

Oh boy, converting the whole codebase from vb.net to c#

Pain point 1: CType all over the place (Convert.To*)
Pain point 2: almost everything is static!
Pain point 3: "I learned about DI just 3 months ago..."
Paint point 4: deployments ever happened by hand!

But I'm happy to be there because the guy who's running the thing is a very nice one and he's absolutely grateful for every bit of learning lesson I give him.

Business Continuity / DR 101...
How could GitLab go down? A deleted directory? What!
A tired sysadmin should not be able to cause this much damage.
Did they have a TESTED dr plan? An untested plan is no plan. An untested plan does not count. An untested plan is an invitation to what occurred.
That the backups did not work does not cut it - sorry GitLab. Thorough testing is required before a disruptive event.
Did they do a thorough risk assessment?
We call this a 'lesson learned' in my BC/DR profession. Everyone please learn by it.
I hope GitLab is ok.

I hate people who think they are always right.

A coworker who seemed to be a friend turns out to be an emotionally needy narcissist who seems to think that he is a perfect human being and is the best example of how to live.

Long story short is that we did some bonding via alcohol and smoking cigarettes. Especially when I was in a bad period in my life where I had little self confidence, was in a bad financial situation and overshared many details abound my personal life.

And yeah we also work as software devs in the same team but I started avoiding working with him directly, because due to his seniority he overcomplicates things a lot to the point where stuff gets postponed for months. Meanwhile I am a simple guy, I do my tasks and if they are not up to the standard I just work on the feedback until Im up to the standard, thats it. Its just a job for me, for him its a way of life and he considers himself to be basically an artist.

Hes always trying to prove me something, showing that the "long way" is the best way and so on. In reality I dont give a fuck about him. I live my own life and I have my own priorities. I work fulltime in one job, also I work part time as a freelancer and in total I make about 20 percent more than he does. Previously before this job I owned my own company where for 2 years I ran my own projects which generated a decent revenue. I know what is hard work and how to sacrifice myself in order to achieve results. I am more pragmatic and I have some limitations of what I can be good at (since I have a shitty working memory due to my ADHD). So I have systems in place and bottom line is that I earn a decent living and my skillset is different. Yeah I agree that in some ways he is better than me, but dude has such a massive inflated ego that now he thinks that he unlocked some sort of universal wisdom and now hes suddenly experienced in every field of life and his opinion is the right one.

This guy takes a massive pride in how good software engineer he is and in every topic or interaction he tries to one up me. Which most of the time is just his preference or in order to gain a 0.0001 percent performance increase. Dude is basically a big walking ego and since "we are close now" his ego started bleeding into personal relationship.

In my personal life, Im in a stable relationship, thinking of proposing soon and getting married. I already co-own an apartment with my current girlfriend. Everything is serious and planned, Im soon to be 30 years old. He is the same age but he still thinks hes young hot shit and all he cares about is getting shitfaced a couple times a week after work and he doesnt really have any other hobbies. He has a girlfriend but I dont see any future in there TBH.

So what I did now is I started putting some distance between us. No more drinking every week with him, maybe maximum once in 2 or 3 weeks. I started working from home more. Also I stopped sharing my personal life with him. Each time when he thinks he is right I just go along with it and dont even pay attention to his emotional manipulations. I just hope one day he fucks off completely and I wont give in to his gaslighting. Maybe in a few months I will be leaving this job, so I will never have to deal with him again.

Lesson learned: dont be vulnerable to coworkers who you bond together only via alcohol.

I was Just college fresher who completed his Engineering. My first week in the office. And a system was provided to me, since it was support project so I was given direct access to production database.

Fresher + Production Database + Access of Admin credentials = Worst Possible Combination

So it was my night shift, I was told to update new tariff plan for our client (which was one of the largest telecom service in India) .

If someone recharges for more than 200 Rupee, that person will get 10% or 20% extra talk time. Which was only applicable for particular circle (Like Bihar and Rajasthan).

Since I was fresher, I was told to update given query from my senior employee which he shared on the shared folder. Production downtime was in the mid night, so at that time I updated that query on the production database.

Query successfully updated. I completed my night shift, went home and slept.

When I woke up, I saw my mobile it had 200+ missed calls from different locations of India. They were Circle heads of that telecom service provider who contacted me. I realized something unexpected is expecting me.

Then at that moment my team lead called me and he asked me to come office right away.

Reminding you I was a fresher, I was shivering. What have I done there?

When I reached office, I came to know that the query I updated on production bombarded.

Every person who recharged that day (duration from midnight to morning 10 AM) got 10 times or 20 times more talktime.

A part of Query was something like this where error was made:

TalkTime = RechargeAmount + RechargeAmount * 10/100; (Bihar)
or

TalkTime = RechargeAmount + RechargeAmount * 20/100; (Rajasthan)
But instead of this query, I updated below one:

TalkTime = RechargeAmount + RechargeAmount * 10;
or

TalkTime = RechargeAmount + RechargeAmount * 20;
In a span of 10 hours, that telecom service lost revenue of 6.5 crore Rupees. Thanks to recovery team they were able to recover 6 crore but still 50 lakh Rupees were in loss.

One small query, and approx 1 million dollar was on stake.

Aftermath of this incident

My Mistake:

I should have taken those queries on mail. Or, there should have been mail communication regarding this.
Never ever do anything over oral communication. Senior employee who did this denied and said he provided correct query, and I had no proof of communication.
I told them, it was me who executed that query on production. Since I was fresher, and took my responsibility of that incident. My team lead rescued me from that situation.
Lesson Learned:

Always test your query and code multiple times before you execute or Go live it on production.
Always have email communication for every action you take on production.
Power comes with responsibility. If you have admin credentials of production never use it for update/delete/drop until you are sure.
Don’t take your job lightly.
I was not fired from that Job, but I have learnt my lesson very well.

#1 life lesson learned from coding: There are things I just can’t be good at no matter how hard I try.

Becoming member of a political party.

I met a lot of smart people, had many great debates about different issues, yet most of all: I learned how dangerous group dynamics can be. (It's insane how fast Us-vs-Them-group-thinking can manifest itself.) I learned to reflect myself (the hard way) and that if I want to convince someone, rational arguments is not enough if you are a dick about it and that sometimes the how you say things is so much more powerful than the what.

Basically, I learned a valuable lesson on how (not) to communicate. I still profit from that on a daily basis in my work as a developer.

(On the other hand, the whole experience made me rather cynical about the state of the world at large.)

Rant at myself for being a moron.

Manually tried moving some InnoDB stuff around on a local server and corrupted a load of databases, with no backups since June 28th. Spent all day yesterday trying to recover with no luck 😑

Lesson learned: need to backup databases more regularly. Any good tools?

Lesson learned: never fuck up with the python version that comes with a distro. I spent the whole day re-installing Linux Mint on a new partition and transferring home folder to the new partition. 😣😣😣

I'm an idiot 😥

TL;DR; do your best all you like, strive to be the #1 if you want to, but do not expect to be appreciated for walking an extra mile of excellence. You can get burned for that.

They say verbalising it makes it less painful. So I guess I'll try to do just that. Because it still hurts, even though it happened many years ago.

I was about to finish college. As usual, the last year we have to prepare a project and demonstrate it at the end of the year. I worked. I worked hard. Many sleepless nights, many nerves burned. I was making an android app - StudentBuddy. It was supposed to alleviate students' organizational problems: finding the right building (city plans, maps, bus schedules and options/suggestions), the right auditorium (I used pictures of building evac plans with classes indexed on them; drawing the red line as the path to go to find the right room), having the schedule in-app, notifications, push-notifications (e.g. teacher posts "will be 15 minutes late" or "15:30 moved to aud. 326"), homework, etc. Looots of info, loooots of features. Definitely lots of time spent and heaps of new info learned along the way.

The architecture was simple. It was a server-side REST webapp and an Android app as a client. Plenty of entities, as the system had to cover a broad spectrum of features. Consequently, I had to spin up a large number of webmethods, implement them, write clients for them and keep them in-sync. Eventually, I decided to build an annotation processor that generates webmethods and clients automatically - I just had to write a template and define what I want generated. That worked PERFECTLY.

In the end, I spun up and implemented hundreds of webmethods. Most of them were used in the Android app (client) - to access and upsert entities, transition states, etc. Some of them I left as TBD for the future - for when the app gets the ADMIN module created. I still used those webmethods to populate the DB.

The day came when I had to demonstrate my creation. As always, there was a commission: some high-level folks from the college, some guests from businesses.

My turn to speak. Everything went great, as reversed. I present the problem, demonstrate the app, demonstrate the notifications, plans, etc. Then I describe at high level what the implementation is like and future development plans. They ask me questions - I answer them all.

I was sure I was going to get a 10 - the highest score. This was by far the most advanced project of all presented that day!

Other people do their demos. I wait to the end patiently to hear the results. Commission leaves the room. 10 minutes later someone comes in and calls my name. She walks me to the room where the judgement is made. Uh-oh, what could've possibly gone wrong...?

The leader is reading through my project's docs and I don't like the look on his face. He opens the last 7 pages where all the webmethods are listed, points them to me and asks:
LEAD: What is this??? Are all of these implemented? Are they all being used in the app?
ME: Yes, I have implemented all of them. Most of them are used in the app, others are there for future development - for when the ADMIN module is created
LEAD: But why are there so many of them? You can't possibly need them all!
ME: The scope of the application is huge. There are lots of entities, and more than half of the methods are but extended CRUD calls
LEAD: But there are so many of them! And you say you are not using them in your app
ME: Yes, I was using them manually to perform admin tasks, like creating all the entities with all the relations in order to populate the DB (FTR: it was perfectly OK to not have the app completed 100%. We were encouraged to build an MVP and have plans for future development)
LEAD: <shakes his head in disapproval>
LEAD: Okay, That will be all. you can return to the auditorium

In the end, I was not given the highest score, while some other, less advanced projects, were. I was so upset and confused I could not force myself to ask WHY.

I still carry this sore with me and it still hurts to remember. Also, I have learned a painful life lesson: do your best all you like, strive to be the #1 if you want to, but do not expect to be appreciated for walking an extra mile of excellence. You can get burned for that.

Biggest lesson learned for me was believing some guy wearing a comb over & a fake tan who sounds like a car salesman. He claimed selling web app services to companies was no different than selling cars. It turns out that a lot of investors were not too happy that the company went under (b4 anything was released) b/c the CEO/CFO somehow managed to burn several million dollars on first class flights, cruises, 5 star restaurants, a luxury company car (for himself), hotels, etc.,. oh and even some fake tans!

Worst part about all that he wasn't even worth sueing because he had no money after all that. He even signed the 'company' car over to one of his kids!

You know shit is going to hit the fan if the sentence "c++ is the same as java" is said because fuck all the underlying parts of software. It's all the fucking same. Oh and to write a newline in bash we don't use \n or so, we just put an empty echo in there. And fuck this #!/bin/bash line, I'm a teacher. I don't need to know how shit works to teach shit. Let's teach 'em you need stdio for printf even tho it compiles fine without on linux (wtf moment number one, asking em leaves you with "dunno..") and as someone who knows c you look at your terminal questioning everything you ever learned in your whole life. And then we let you look into the binaries with ldd and all the good stuff but we won't explain you why you can see a size difference in the compiled files even tho you included stdio in the second one, and all symbol tables show the exact same thing but dude chill, we don't know what's going on either.
Oh and btw don't use different directory names as we do in our examples. You won't find your own path, there is no tab key you can press to auto-fill shit.
But thats not everything. How about we fill a whole semester with "this is how to printf" but make you write a whole game with unity and c#. (not thaught even the slightest bit until then btw)
Now that you half-assed everything because we put you in a group full of fucks who don't even know what a compiler is but want to tell you you don't know shit and show you their non-working unfinished algorithms in some not-even-syntax-correct java...

...how about we finally go on with Algebra II: complex numbers, how they are going to fuck up your life, how we can do roots of negative numbers all of the sudden and let you do some probability shit no one ever fucking needs. BUT WHY DON'T YOU KNOW EVERYTHING ALREADY HMMMMM, IT'S YOUR SECOND LESSON, YOU WENT TO SCHOOL PLS BE A MATH PRO ASAP CUS YOU NEED IT SO MUCH BUT YOU DON'T NEED TO KNOW PROPER SYNTAX, HOW MEMORY MANAGEMENT WORKS, WHAT A REFERENCE IS AND PLS FINALLY FORGET THE WORD "ALLOCATION" IT DOESN'T PLAY A SINGLE ROLE YOU ARE STUDYING SOFTWARE DEVELOPMENT WHY ARE YOU SO BAD AT ECONOMICS IT MAKES NO SENSE I MEAN YOU HAD A WHOLE SEMESTER OF HOW TO GREET SOMEONE IN ENGLISH, MATHS > ECONOMICS > ENGLISH > FUCKING SHIT > CODING SKILL THATS HOW THE PRIORITIES WORK FOR US WHY DON'T YOU GET IT IT MAKES SO MUCH SENSE BRAH

Run the tests before you commit, even if it was just a minor modification.

(Yep, I broke most of the tests by changing only a couple of lines. Lesson learned.)

Never! ever! EVER!!! run sudo rm -fr * inside your home directory! Hard lesson learned on a Monday :(

P.S it was not intentional at all!

I just asked a client if he wants a contact form instead of just writing down an email address on their contact page.

Now I'm trying to explain to him how building a full blown CRM is outside the scope the business website we agreed to build.

Lesson Learned: Never make suggestions.

Plan plan and then plan again

Especially on a hardened server in an off-site facility.

If you fuck up your SSH then you will be in trouble.

Somebody ranted about his teacher showing windows presentation and teaching nothing. I wanted to comment that post but i have enough material to make the whole rant out of it.

Well at least you have those presentations! In my school we have 2 IT classrooms one with win xp, 1ghz cpu, 0,5gb ram computers and one with win vista, 2 core 2ghz cpu and 2gb of ram PCs.

Guess what room our teacher is using... of course the worse one! The second one is fine, few years ago another theacher had been using it!

I tried to convince him to change rooms but he is coming up with silly exciuses! (like "server is not working here!", well i fixed it with my friend but why are you even talking about it when you are not using yours in old class!)

PS. That server is useless anyway, every pc is connected to router that is connected to internet so supervisor pc is not mandatory, only acces restriction is enforced by win accounts.

I heard from students from my class (that picked that optional IT course) (i'm in high school) that gimp is not working because pc's are so bad!
Sometimes even notepad frezzes.🤔

Not only class is shite but teacher clearly has no idea what is he doing. (in order to pass the final from IT you need to learn simple C++, up to simple foo objects) and of course he isn not even talking about that! On one lesson about sorting algorithms he gave everybody 10 small pieces of paper with numbers on them and told everybody to sort them manualy, because he didnt know how to do it himself! So there is no doubt they wont be able code it.

I need to mention that i volontered to "clean, fix" that classroom (in order to convince teacher to move). And in that class i saw programms written in c++ on every computer! That means somebody was teaching propely before! 😣

I feel sorry for those guys, they are just waisting time. I would fall for it as well but i decided i can learn coding in home ;).
Well, results are shocking, after 1 month of coding i learned C# and i can basicly make any algorithm i ever wish. I learned about computer operation so well that i can nearly teach computer science. (i helped my friend in usa that is a electronic student with that and i'm very proud of it 😁) and it class still can't even use all 3 loops correctly... 😥 Ok i must admit i have been coding for a looooong while so i had time to learn basic c,c++ and pc operations before, but point still stands.

Why the hell are you wasting life of those studends? Why are you giving them a choice to learn coding WHEN YOU CANT EVEN USE PC YOURSELF?! (that it course is optional so you can apply if you want so)

I dont regret not bothering about it.

Have been playing the pirated version of Rust for 30+ hours with no issues.

Decide to buy the game and every fucking time the game turns into Chrome and consumes all my RAM forcing Windows to show the low on memory dialog.

Lesson learned I guess.

Lesson learned: Always use node LTS in production, library maintainers are lazy af.

It was the last year of high school.

We had to submit our final CS homework, so it gets reviewed by someone from the ministry of education and grade it. (think of it as GPA or whatever that is in your country).

Now being me, I really didn’t do much during the whole year, All I did was learning more about C#, more about SQL, and learn from the OGs like thenewboston, derek banas, and of course kudvenkat. (Plus more)

The homework was a C# webform website of whatever theme you like (mostly a web store) that uses MS Access as DB and a C# web service in SOAP. (Don’t ask.)

Part 1/2:

Months have passed, and only had 2 days left to deadline, with nothing on my hand but website sketches, sample projects for ideas, and table schematics.

I went ahead and started to work on it, for 48 hours STRAIGHT.

No breaks, barely ate, family visited and I barely noticed, I was just disconnected from reality.

48 hours passed and finished the project, I was quite satisfied with my it, I followed the right standards from encrypting passwords to verifying emails to implementing SQL queries without the risk of SQL injection, while everyone else followed foot as the teacher taught with plain text passwords and… do I need to continue? You know what I mean here.

Anyway, I went ahead and was like, Ok, lets do one last test run, And proceeded into deleting an Item from my webstore (it was something similar to shopify).

I refreshed. Nothing. Blank page. Just nothing. Nothing is working, at all.

Went ahead to debug almost everywhere, nothing, I’ve gone mad, like REALLY mad and almost lose it, then an hour later of failed debugging attempts I decided to rewrite the whole project from scratch from rebuilding the db, to rewriting the client/backend code and ui, and whatever works just go with it.

Then I noticed a loop block that was going infinite.

NEVER WAIT FOR A DATABASE TO HAVE MINIMUM NUMBER OF ROWS, ALWAYS ASSUME THAT IT HAS NO VALUES. (and if your CPU is 100%, its an infinite loop, a hard lesson learned)

The issue was that I requested 4 or more items from a table, and if it was less it would just loop.

So I went ahead, fixed that and went to sleep.

Part 2/2:

The day has come, the guy from the ministry came in and started reviewing each one of the students homeworks, and of course, some of the projects crashed last minute and straight up stopped working, it's like watching people burning alive.

My turn was up, he came and sat next to me and was like:

Him: Alright make me an account with an email of asd@123.com with a password 123456

Me: … that won't work, got a real email?

Him: What do you mean?

Me: I implemented an email verification system.

Him: … ok … just show me the website.

Me: Alright as you can see here first of all I used mailgun service on a .tk domain in order to send verification emails you know like every single website does, encrypted passwords etc… As you can see this website allows you to sign up as a customer or as a merc…

Him: Good job.

He stood up and moved on.

YOU MOTHERFUCKER.

I WENT THROUGH HELL IN THE PAST 48 HOURS.

AND YOU JUST SAT THERE FOR A MINUTE AND GAVE UP ON REVIEWING MY ENTIRE MASTERPIECE? GO SWIM IN A POOL FULL OF BURNING OIL YOU COUNTLESS PIECE OF SHIT

I got 100/100 in the end, and I kinda feel like shit for going thought all that trouble for just one minute of project review, but hey at least it helped me practice common standards.

Pinterest, one of the most wonderful and elegantly designed products has gone to rats.

The performance was smooth, the UX was kickass, the content was lit.

I once watched Ben's interview and absolutely loved his thought process on how he identified a problem and went ahead to build a solution for it.

Unlike Facebook/Instagram, which are designed to make you compete for dopamine shots and trigger jealousy, Pinterest was kind of different where you have a custom feed and yet no comparison or showing off. Cool right?

However, towards the end of the interview, Ben did mention that they are going (or already bagged) another round of cash. I was sceptical of why that was needed when they already had good reach, scaled product, and overall a stable ecosystem. They could instead focus on exit plans.

Pinterst has become a piece of garbage now. Cluttered with all the original features, which made it different, have been taken away. Moreover, not only the product is complicated and difficult to understand (let alone use), it is bloated with ads. The amount of ads and redirection of every search result to their shopping tab is just nauseating.

Feed has same content for days, if not weeks. You can no way customise the content been showcased and no matter how many times you report unwanted or inappropriate images, shit still shows up. The algo is rusted now.

Remember kids, this is NOT how you build and grow products. Lesson learned, capitalism has the power to destroy everything.

Me: What if I use navigation props in EF Core, what might go wrong?

*tests API call*
*120 seconds later finally got result*

Me: I better undo my changes and stick with 2 seconds response time O_O

Today I learned what actually happens if you don't close your database connections (because you forget) after you've used it. Feck all happens for the first 9 requests, and after that error 504 😂

20 issues assigned to me this sprint with very vague titles and in the requirements it says "See *person name* for details"

Lesson learned: Never go on vacation during the spring planning meeting.

Hidden pixel just scratched my finger while I was wiping the screen with my palm. Lesson successfully learned.

So I'm sitting there in Android practice. I already have some experience with Android, so the exercises they make us do are quite easy for me. Nevertheless I start doing the exercises, when the teacher tells us that whoever implemented last week's exercise well gets a + point (and a pat on the back).

Implementing it well only means that you used a Model class for your Model (basic stuff). I raise my hand, hoping to get that sweet ++.
Teacher comes over. My laptop dies. Can't boot for shit. All the while I'm losing my shit. Then I remember that I have the code up on Github (I started using git for these small projects, to practice it). I showed the teacher my code on Github and the app on my phone (I debug from my phone because there is no way I can run an emulator on my laptop). I got the ++ and the teacher was delighted that someone was using Git, even though they didn't *have to*.

I definitely learned my lesson there. I'll be using Github for all of the small shitty projects we have from now on. My Github repo might look like garbage, but I will have peace of mind.

I spend all morning on trying to solve an Algo problem for upcoming interview practice (Euler #3) that comes down to implementing IsPrime.

I remember reading once how Sieve of Eratosthenes

Isa the right way to go do when I first started I wanted to use that.

Then I couldn't think of the right code though so I went with Brute Force (for all numbers upto X see X is divisible by it)

It actually worked but I wanted to just try the "right way".

It's way slower and actually ended up with the wrong answer...

But at this point I don't give a **** anymore.

I guess lesson learned... Use Brute Force first... Then optimise for a problem more elegant solution.

Customer wants a place to list his products he sells through other sites. He doesn’t have much money, but he’s a referral from a reliable customer, so we arrange a payment plan. We agree on the details, including a place to post his wares.

Then he tells me he wants to post a few thousand items at a time. I decide to throw in a loading system I built for a previous project.

Then he can’t figure out how to add images. Add a way for him to upload them all as a single zip; no good.

Long story short, let myself get conned into developing a full-on Amazon import system that auto-detects several categories automatically AND imports the images. For no additional cost because I felt bad asking for more and we were working through a language barrier.

Third installment payment never comes.

Lesson learned.

So I wrote the script for the GAL in WinCupl for our project. I used the operators: ! for NOT, * for AND, + for OR

me: *writes code*
me: *compiles it*
compiler: error, unknown operation.
me: wtf but thats how its done, isnt it?
friend: u used the wrong operators. didnt u read the manual?
me: smh i didnt, i invented the syntax xD

lesson learned: always read manual first before writing it directly without knowing the syntax

Am I the only one who gets intimidated when shit its roof?

Yesterday, during crucial business hours, one of the major OMS db column type got overflowed. Caused around 30 mins downtime and then later, pool of all connections with high concurrent requests flushed down stream which caused thunder herd.

One by one.. all services went down; Fucking java service couldn't even start because of load..

This is the moment I fell in love with GoLang. We shard request using GoLang service, it just started and picked up the load beautifully..

At the end, it is around 6 millions business loss, but a good lesson learned :)

For me side projects have been things I'll make to do something that others will use. Some people call it innovation, some call it side business. But that's how i look at side projects. So the points below are more to do with entrepreneurial experiences.

1. If there are more people involved, ensure that there is work for everybody (also level of commitment is tested by how much they put in). Also have as varied set of skills as possible. So that areas are well defined in terms of scope of work and areas of expertise.
2. Put in some money. Money is super glue. It will ensure that you're committed to the thing. Things change when decent amount of money is involved. You're invested, as may be others.
3. Learn something as an intention. This has nothing to do with the learnings you'll get on the way. This one seems obvious, but nevertheless needs to be said.
4. Set timelines and deadlines. Ask someone else to check on whether you're keeping on to your deadlines or not.
5. Don't go live without proper testing.
6. Make something you feel strongly about. The path will be exciting and clear.
7. Talk to people to get their feedback on everything. You may not like what's told to you. Listen dispassionately. Absorb everything. Feel miserable. But listen and think about it after sleeping over it.
8. Continuation of above point. Talk to varied set of people in terms of backgrounds. You would be surprised as to how differently people think.
9. Ask for help when stuck. Kill your ego and be vulnerable.
10. Check out what's already available. What value are you adding. And make it!

I often ask my colleagues about their mess ups on the job and that, to me, says a lot about them.

See, we devs have this unspoken rule between us (in my opinion) that we don't discuss our screw-ups whether it's the resume, the interview or at the job.

Are you really telling me that you've worked 5+ years in software industry and never messed up ONCE? Or were/are you in a position where you screwing up wouldn't create a dent for your team processes?

I can trust a dev more, who admits their screw ups because I know they have learned a valuable lesson and they are accountable for their actions.

How many here have friends that are like
Friend:"hey, heard so much good about Linux, can you install it for me?"
Me:"sure. What do you intend to use it for? "
Friend:"Facebook. Mostly Facebook. And some Instagram."
Me:"mmm k. I'd like to show case a bunch a distros and you pick your favourite."

One week later.
Friend:"OMG Linux sucks, I bought {game} but it cannot install..."

Lesson learned?
Remember to ask about likely headache candidates (like games), before doing one such "favor"

I did one thing really smart, schedule my vacation and tell them no access to computer. I also did a stupid thing. I told them 2weeks ahead. So for the next 2weeks I’m going to work double everyday. Lesson learn.

Story time... (Not long though)

My current employment status is quite strange. Basically I'm a freelancer. My former boss asked me to throw a half paid job and include three days worth of work for free just because it would be convenient.

When I told him no way - he was very uppset and offended and told me how disappointed he was.

Lesson learned: If you work for free and offer to "help" someone out, it will mostly lead to more queries for free of charge gigs. Don't do it like I did. Fuck that shit, thanks for appreciating my effort.

Not sure if many people heard about nltk in python but I'm currently using a lot now for research.

So one day I was doing multiprocessing while using lemmatizer in nltk, for those who don't know, lemmatizer is a thing that change the word to its base form. So it is like, ran to run, bitches to bitch.

Anyway, the nltk package, to ensure it does not take too much memory, here's what it does: it loads a data file, and once it is loaded and accessed for the first time, it breaks the data file into CSV file. And since I was doing multiprocessing, the data file is accessed for multiple time while it can only be loaded once, hence error happened.

Instead of changing my code, which I think is good already, I went to the package directory of nltk and directly changed the source code from there and now the code works perfectly.

I'm very proud of my self at the moment, this is a very good lesson that I've learned: always look for alternatives. And suck it, nltk.

So I want to inform my internet provider of my new phone number, but I can't remember any of my login info for their web interface because I never used it. Luckily, they have a "forgot my username" function, where I submit my email address and get a confirmation that my username has been sent to me.

Yet, I just don't get said email. I try again, but no avail. So I just guess my username and use their "forgot password" form, which – hooray! – confirms it just sent my an email.

But I don't get any email. I retry, I retry after a day, but no automatic response. I remember a incident a few years back when I didn't get some automatically generated mails from a company and decide to contact their support if they could just reset my password manually.

Nearly a week passes.

Now I received the answer. I just don't have an account.

Lesson learned: Next time I'll just input garbage first to check if those forms are sane.

In person interview is normally less work than take home test.

Lesson learned.

Finally figured out why my team’s lab project was taking so long to compile. Named imports of material-ui icons. Lesson learned!

I think my biggest issue is learning, I never really learned how to 'learn' like take notes or 'study' things. My method of learning is more akin to skimming books (not knowing a good way for me to take notes on it) and articles, while also just testing stuff like I'm throwing things at a wall till it sticks and I pick up a lesson from that after wasted hours of trial and error that might have been avoided with properly knowing how to learn.

I need to figure out how to properly note-take and learn and properly go through all the books I've 'read' but never really learned.
