Oh, man, I just realized I haven't ranted one of my best stories on here!
So, here goes!
A few years back the company I work for was contacted by an older client regarding a new project.
The guy was now pitching to build the website for the Parliament of another country (not gonna name it, NDAs and stuff), and was planning on outsourcing the development, as he had no team and he was only aiming on taking care of the client service/project management side of the project.
Out of principle (and also to preserve our mental integrity), we have purposely avoided working with government bodies of any kind, in any country, but he was a friend of our CEO and pleaded until we singed on board.
Now, the project itself was way bigger than we expected, as the wanted more of an internal CRM, centralized document archive, event management, internal planning, multiple interfaced, role based access restricted monster of an administration interface, complete with regular user website, also packed with all kind of features, dashboards and so on.
Long story short, a lot bigger than what we were expecting based on the initial brief.
The development period was hell. New features were coming in on a weekly basis. Already implemented functionality was constantly being changed or redefined. No requests we ever made about clarifications and/or materials or information were ever answered on time.
They also somehow bullied the guy that brought us the project into also including the data migration from the old website into the new one we were building and we somehow ended up having to extract meaningful, formatted, sanitized content parsing static HTML files and connecting them to download-able files (almost every page in the old website had files available to download) we needed to also include in a sane way.
Now, don't think the files were simple URL paths we can trace to a folder/file path, oh no!!! The links were some form of hash combination that had to be exploded and tested against some king of database relationship tables that only had hashed indexes relating to other tables, that also only had hashed indexes relating to some other tables that kept a database of the website pages HTML file naming. So what we had to do is identify the files based on a combination of hashed indexes and re-hashed HTML file names that in the end would give us a filename for a real file that we had to then search for inside a list of over 20 folders not related to one another.
So we did this. Created a script that processed the hell out of over 10000 HTML files, database entries and files and re-indexed and re-named all this shit into a meaningful database of sane data and well organized files.
So, with this we were nearing the finish line for the project, which by now exceeded the estimated time by over to times.
We test everything, retest it all again for good measure, pack everything up for deployment, simulate on a staging environment, give the final client access to the staging version, get them to accept that all requirements are met, finish writing the documentation for the codebase, write detailed deployment procedure, include some automation and testing tools also for good measure, recommend production setup, hardware specs, software versions, server side optimization like caching, load balancing and all that we could think would ever be useful, all with more documentation and instructions.
As the project was built on PHP/MySQL (as requested), we recommended a Linux environment for production. Oh, I forgot to tell you that over the development period they kept asking us to also include steps for Windows procedures along with our regular documentation. Was a bit strange, but we added it in there just so we can finish and close the damn project.
So, we send them all the above and go get drunk as fuck in celebration of getting rid of them once and for all...
Next day: hung over, I get to the office, open my laptop and see on new email. I only had the one new mail, so I open it to see what it's about.
Lo and behold! The fuckers over in the other country that called themselves "IT guys", and were the ones making all the changes and additions to our requirements, were not capable enough to follow step by step instructions in order to deploy the project on their servers!!!

My mentor/guider at my last internship.
He was great at guiding, only 1-2 years older than me, brought criticism in a constructive way (only had a very tiny thing once in half a year though) and although they were forced to use windows in a few production environments, when it came to handling very sensitive data and they asked me for an opinion before him and I answered that closed source software wasn't a good idea and they'd all go against me, this guy quit his nice-guy mode and went straight to dead-serious backing me up.
I remember a specific occurrence:
Programmers in room (under him technically): so linuxxx, why not just use windows servers for this data storage?
Me: because it's closed source, you know why I'd say that that's bad for handling sensitive data
Programmers: oh come on not that again...
Me: no but really look at it from my si.....
Programmers: no stop it. You're only an intern, don't act like you know a lot about thi....
Mentor: no you shut the fuck up. We. Are. Not. Using. Proprietary. Bullshit. For. Storing. Sensitive. Data.
Linuxxx seems to know a lot more about security and privacy than you guys so you fucking listen to what he has to say.
Windows is out of the fucking question here, am I clear?
Yeah that felt awesome.
Also that time when a mysql db in prod went bad and they didn't really know what to do. Didn't have much experience but knew how to run a repair.
He called me in and asked me to have a look.
Me: *fixed it in a few minutes* so how many visitors does this thing get, few hundred a day?
Him: few million.
Me: 😵 I'm only an intern! Why did you let me access this?!
Him: because you're the one with the most Linux knowledge here and I trust you to fix it or give a shout when you simply can't.
Lastly he asked me to help out with iptables rules. I wasn't of much help but it was fun to sit there debugging iptables shit with two seniors 😊
He always gave good feedback, knew my qualities and put them to good use and kept my motivation high.
Awesome guy!4 -
I'm never making fun of people who go to Stack Overflow for answers ever again.
I mean, have you guys seen this? A leap-second causing 100% CPU use in MySQL, and a dude figures it out like it was nothing, and provides a quick solution!

FML. An overreaching supergenius "architect" and a database team:
A: "We have decided that apps should use mysql. Install a MySQL so we match cloud"
DBA: "we don't have an image or experience with MySQL. We have mssql and Oracle "
A: "ok, use mssql in data center and mysql in production cloud"
DBA: "that's... not going to work well"
A: "just do it!"
...
Me, reading this shit, sends email: "ignoring the fact that we have more than 500 queries in this application which will need to be checked and most likely rewritten, how are we supposed to test the mysql queries without production access?"
A: "just use mssql local and MySQL in cloud"
M: "... Just to make sure I understand, you want us to write queries for mssql, test them locally, and then write separate queries, with a separate SQL connection abstraction that deploys to production? Again, how are we going to test this?"
A: "no, use same queries, should be fine"
M: "they really won't, they're different dialects"
A: "do the needful, make work!"

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.5 -
Hello there, just couple of words about PHP. I've been develop on PHP more than 10 years, I've seen it all 3,4,5,{6},7. Yes PHP was not good in terms of engineering and patterns, but it was simple, it was the most simple language for web to start those days. It was simple as you put code into file, upload it via FTP and it works. No java servlets, no unix consoles, no nothing, just shared hosting account was enough to host site, or even application with database. As database everybody used to have mysql, again because its simple to start and easy to maintain. So PHP+MySQL became industry standard on Web during 00-2012, and continues in some way.
You can write HTML and logic inside single file, within php code, even more single file may content few pages, or even kind of framework. That simplicity and agility sticks everybody who wants to develop sites with PHP.
This is pretty much about why it is so popular.
Each good or wannabe PHP developer in an early days write its own framework or library (like in javascript this days because of nodejs)
Imagine that PHP has hadn't have package manager, developers used to have host packages on their own sites, then various packages catalog sites created, and then finally composer. A gazillions of php code had spread over internet, without any kind of dependency control. To include libraries to your projects you have to just write include, or require. Some developers do it better than others.
So what we have ? A lots of code, no repositories, zip archives with libraries, no dependency control.
Project that uses that kind of code are still alive even today, they are solid hose of cards, and unmaintainable of course.
And main question that I'm trying to answer is Why PHP is not good ?
- First is amount of legacy code which people copy and pasted into their project, spread it even more like a virus.
- Lack of industry standards at the beginning lead to a lots of bad practices among developers. PHP code usually smells.
open source php projects in early days was developed in same conditions so even in phpbb, phpnuke, wordpress, drupal used to have a lot of bad practices in their codebase. So php developers usually not study by another library, instead they write their own frameworks/libraries.
- "It works", - there are no strong business demands, on web development, again because lack of standards, and concerns.
This three things are basically same, they linked to each other and summarize of answer of why PHP have strong smells and everybody yelling against it.
Whats is with PHP nowadays ? Of course PHP today is more influenced by good practice of webdev. Composer, Zend, Laravel, Yii, Symphony and language it self became more adult so to say, but developers...
People who never tried anything except PHP are usually weaker in programming and ecosystem knowledge than people who tried something else, python, perl, ruby, c for instance.
Summary
PHP as any other programming language is a tool. Each tool has its own task. Consider this and your task requirements and PHP can be just good enough solution.
"PHP is shit" - usually you heard that from people who never write strong applications on PHP and haven't used any good tools like Symphony or Laravel.
Cheap developers, - the bigger community, the more chance to hire cheap developers, and more chance to get bad code. That can be applied on any other language.
PHP has professionals developers, usually they have not only php on scope.
That's all folks, this is very brief, I am not covering php usage early days in details, but this is good enough to understand the point.
Enjoy.8 -
Fuck mysql charset shit. Pretty easy to forgot setting charset in server side config file. And after creating several databases/tables, boom! All in latin1. That's just so convenient. are you kidding me? Why would any modern database have their default charset to be latin1??? rather than utf8? Oh, just forgot again, that's utf8fuckingmb4 on mysql land.6

The website for our biggest client went down and the server went haywire. Though for this client we don’t provide any infrastructure, so we called their it partner to start figuring this out.
They started blaming us, asking is if we had upgraded the website or changed any PHP settings, which all were a firm no from us. So they told us they had competent people working on the matter.
TL;DR their people isn’t competent and I ended up fixing the issue.
Hours go by, nothing happens, client calls us and we call the it partner, nothing, they don’t understand anything. Told us they can’t find any logs etc.
So we setup a conference call with our CXO, me, another dev and a few people from the it partner.
At this point I’m just asking them if they’ve looked at this and this, no good answer, I fetch a long ethernet cable from my desk, pull it to the CXO’s office and hook up my laptop to start looking into things myself.
IT partner still can’t find anything wrong. I tail the httpd error log and see thousands upon thousands of warning messages about mysql being loaded twice, but that’s not the issue here.
Check top and see there’s 257 instances of httpd, whereas 256 is spawned by httpd, mysql is using 600% cpu and whenever I try to connect to mysql through cli it throws me a too many connections error.
I heard the IT partner talking about a ddos attack, so I asked them to pull it off the public network and only give us access through our vpn. They do that, reboot server, same problems.
Finally we get the it partner to rollback the vm to earlier last night. Everything works great, 30 min later, it crashes again. At this point I’m getting tired and frustrated, this isn’t my job, I thought they had competent people working on this.
I noticed that the db had a few corrupted tables, and ask the it partner to get a dba to look at it. No prevail.
5’o’clock is here, we decide to give the vm rollback another try, but first we go home, get some dinner and resume at 6pm. I had told them I wanted to be in on this call, and said let me try this time.
They spend ages doing the rollback, and then for some reason they have to reconfigure the network and shit. Once it booted, I told their tech to stop mysqld and httpd immediately and prevent it from start at boot.
I can now look at the logs that is leading to this issue. I noticed our debug flag was on and had generated a 30gb log file. Tail it and see it’s what I’d expect, warmings and warnings, And all other logs for mysql and apache is huge, so the drive is full. Just gotta delete it.
I quietly start apache and mysql, see the website is working fine, shut it down and just take a copy of the var/lib/mysql directory and etc directory just go have backups.
Starting to connect a few dots, but I wasn’t exactly sure if it was right. Had the full drive caused mysql to corrupt itself? Only one way to find out. Start apache and mysql back up, and just wait and see. Meanwhile I fixed that mysql being loaded twice. Some genius had put load mysql.so at the top and bottom of php ini.
While waiting on the server to crash again, I’m talking to the it support guy, who told me they haven’t updated anything on the server except security patches now and then, and they didn’t have anyone familiar with this setup. No shit, it’s running php 5.3 -.-
Website up and running 1.5 later, mission accomplished.6 -
Not a rant about anything in particular. Just a summary of some feelings stored in the hateful part of my heart.
Developing for Android: Add this third-party library to your Gradle build. Use (this) built-in Android class to make the thing work.
*Clicks link
Deprecated since API version SUCKMYDICK-7. Use (this) instead
*Clicks link
Deprecated since API version LICKMYBALLS-32. Use...
Developing for Windows: Please use (this) API call. It was literally already available before Bill Gates was born. Carbon dating has placed this item to older than the universe itself and it is likely the entry point for the big bang. It is also still the best way to accomplish (task).
Developing for Linux: "Hmm, I wonder how to use this"

What? Those three sentences didn't explain it enough? Well, maybe you aren't cut out for this type of thing.
JavaScript: you know how it is.
SQL: You expect a decent-quality answer from stack overflow but you always get an outdated and hacky response and it's using syntax from Microsoft SQL. You need MySQL.
C#: A surprising number of Microsoft forum results ranking high on Google. You click on one in hopes that it will be of any sort of quality. You quickly close the tab and wonder why you ever even had hope.
Literally any REST API: Is it "query" or "q"? "UserID" or "user_id"? Oh, fuck, where's the docs again?
You thought you escaped JavaScript, but it was a trick!: Some bullshit library you downloaded to make your other library work redefined one of the global variables in the project you inherited. Now you get 347 "<x> is not a function" errors in your console. Good luck, asshole.
FontAwesome/ Material fonts/ Any icon font pack: You search "Close" for a close button icon. No results. You search "Simplified railroad crossing sign without the railroad". You get a close icon.
I think that's all of my pent up rage. Each of them were too small for an individual rant so I had to do this essay.2 -
Okay so this happened ages ago (nearly five years) but this suddenly came to my mind again.
It was in the first year of my study (currently in my 5th and last year).
I was experimenting around with php and mysql during some free hours. All the insert,delete and so on statements worked perfectly find except for one update statement. Started to debug of course and after a little while of no results I was like "oh yeah right, something like logs exists of course". Looked in the logs but nothing. No matter how I altered my code (rewrote it numerous times for some 'clean starts') it just would not run the update statement.
Alright, time for some class mate help. After multiple hours of debugging with a few classmates, there was still no result at all.
Time to bring in one or more teachers. After hours of debugging, still no result even with the help of a few good teachers.
Decided to give it a rest for that day.
Two weeks later it still was not updating anything/working and I finally gave up.
Till today, I still have no clue what went wrong and it still bugs me from time to time :/4 -
It is once again that time of year when we say farewell to our current interns and say hello to a brand new batch.
The two groups overlap for a few days. During this time the old interns show the new interns the ropes, while the mentors silently weep in the lunchroom having realized that nothing that they've said over the last 12 months has had any effect whatsoever.
Some choice quotes:
---
New Intern: It says 'uncaught exception'.
Old Intern: Oh don't worry that will fix itself on production.
---
OI: Did you pull the code?
NI: Yeah, but I have all these weird brackets everywhere... [merge conflict]
OI: Oh yeah that happens sometimes, just delete them.
---
NI: It says "push to master rejected". [we enforce code reviews]
OI: Ohh that means the server is broken. You should tell someone, they have to reboot it.
---
NI: Where did that file save to? [we use ONLY macOS and Linux]
OI: C:\Users\<your name>\My Documents\...
---
OI: You can use either pgAdmin or MySQL Workbench. I like Workbench better but I couldn't get it to work, it kept giving me errors.
---
And of course...
---
OI: No, we don't use Linux. We use CentOS.

I did the math today. Only 35 more years and I can retire.5 -
MySQL fell down the stairs again and dropped tables all over the datacenter
the affected servers tried to notify me in advance but spamd wasn't able to scan their messages so IT JUST DIDN'T SEND THEM
EVEN IF IT COULD, NAMED COULDN'T RESOLVE ANY MX RECORDS
BECAUSE BEFORE MYSQL CRASHED IT CONVERTED /ETC/RESOLV.CONF INTO AN INNODB TABLE
(AND THEN DROPPED IT)

Hired a new BI developer. She tested reasonably ok in SQL, and certainly showed good strengths in visualising data, plus had a good attitude in the interview. We hired her. She broke her laptop the first day. We got her another then she complained the camera didn't work but didn't realise the lever in front of the camera was to move the privacy shutter off and on.
Assigned her some work of taking queries that are used in a BI tool that targets the transactional database directly, and re-jigging them for Snowflake which we're using as a data warehouse now, aggregating all our data into one place. Yet, she's struggling to understand why the SQL query she's pasted in doesn't work as-is.
I go over it again; the source schemas and tables are this, but in Snowflake we've named them this. She then bemoans how much work that is to change them all - I say use find and replace. She then struggles with Snowflake syntax errors and asks for a guide on T-SQL to Snowflake. I show her Google and say "this is what I did when I hit these problems - search for 'Snowflake equivalent to T-SQL getdate()' or 'how to get current date in Snowflake' but she still doesn't understand. I ask if she's every had to work between T-SQL and MySQL or MySQL and PostgreSQL or Oracle and so on and she says yes. I say the syntax isn't the same, is it? And she goes oh, now I understand.
She scored reasonably in her SQL test but I'm now concerned there's something fundamental missing in her grasp of SQL. I gave her a detailed demo of the tools, I explained in the interview and on her start about our move to a data warehouse for all our apps, and put her through some training plus gave her time to work through our Confluence pages - not expecting she'll remember everything, but more to ensure she recalls they exist and what the general contents are.
Anyhow, that's my rant.6 -
I'm going on vacation next week, and all I need to do before then is finish up my three tickets. Two of them are done save a code review comment that amounts to combining two migrations -- 30 seconds of work. The other amounts to some research, then including some new images and passing it off to QA.
I finish the migrations, and run the fast migration script -- should take 10 minutes. I come back half an hour later, and it's sitting there, frozen. Whatever; I'll kill it and start it again. Failure: database doesn't exist. whatever, `mysql` `create database misery;` rerun. Frozen. FINE. I'll do the proper, longer script. Recreate the db, run the script.... STILL GODDAMN FREEZING.
WHATEVER.
Research time.
I switch branches, follow the code, and look for any reference to the images, asset directory, anything. There are none. I analyze the data we're sending to the third party (Apple); no references there either, yet they appear on-device. I scour the code for references for hours; none except for one ref in google-specific code. I grep every file in the entire codebase for any reference (another half hour) and find only that one ref. I give up. It works, somehow, and the how doesn't matter. I can just replace the images and all should be well. If it isn't, it will be super obvious during QA.
So... I'll just bug product for the new images, add them, and push. No need to run specs if all that's changed is some assets. I ask the lead product goon, and .... Slack shits the bed. The outage lasts for two hours and change.
Meanwhile, I'm still trying to run db migrations. shit keeps hanging.
Slack eventually comes back, and ... Mr. Product is long gone. fine, it's late, and I can't blame him for leaving for the night. I'll just do it tomorrow.
I make a drink. and another.
hard horchata is amazing. Sheelin white chocolate is amazing. Rum and Kahlua and milk is kind of amazing too. I'm on an alcoholic milk kick; sue me.
I randomly decide to switch branches and start the migration script again, because why not? I'm not doing anything else anyway. and while I'm at it, I randomly Slack again.
Hey, Product dude messaged me. He's totally confused as to what i want, and says "All I created was {exact thing i fucking asked for}". sfjaskfj. He asks for the current images so he can "noodle" on it and ofc realize that they're the same fucking things, and that all he needs to provide is the new "hero" banner. Just like I asked him for. whatever. I comply and send him the archive. he's offline for the night, and won't have the images "compiled" until tomorrow anyway. Back to drinking.
But before then, what about that migration I started? I check on it. it's fucking frozen. Because of course it fucking is.
I HAD FIFTEEN MINUTES OF FUCKING WORK TODAY, AND I WOULD BE DONE FOR NEARLY THREE FUCKING WEEKS.
UGH!6 -
I'm so done with flutter.
I wanted to give it a little try by rewriting a small android project I wrote a few years back. It brings some nice concepts especially when it comes to UI related programming but that's all I can really compliment it for. It's nothing more than something to play with as it is right now.
Also I think this text will be hidden behind the read more. Did I successfully bait you with that cat?
The things I truly hate about it:
The ide integration makes me wanna use eclipse again. At least most nonsensical error messages disappear after saving the document on eclipse.
.
Wanna generate a new function? Yeah, let me just place it RIGHT INSIDE THIS FUCKING IMPORT STATEMENT
Over at Google: Let's just rename everything from java slightly different and put it in nonsensical context so that you have to learn all of it again. Also why don't we make it so that the code suggestions only suggest things you already imported, so that you have to look up every little piece shit feature.
When it comes to databases, I must say, I had more fun working with PHP and mysql than with sqFUCKlite. Throwing away the Room components for that? What a joke...
I already said what i think about the syntax here an devrant but I'm more than happy to repeat it here:
The syntax looks like someone looked at C#, Java and JavaScript and then decided to vomit the worst parts of it into a programming language. I can't really classify anything original about it. There are clear inspirations, but they are confusingly mashed together with the other languages making this one nuts of a language.
Android SDK documentation is a blessing in comparison to whatever the fuck flutter tries to do.
I don't think I'll want top touch that Google side project again within the next few years, if it hasn't been replaced with a new side project like billiard by then.5 -
It's 5pm whooooo!
Let's quickly bash this last query out for the day - seeing as I should have finished an hour ago anyway.
Spin up VM, it's been inactive for 6 months.... yay, login... "incorrect password" tries again "incorrect password", did I forgot it... no it's been the same for years,
ok let's try again slowly,
ok logged in,
jump into mysql,
write up this query,
join this table, join that table, join this other table, and this other, and this one, hahaha, and this one over here... sweet it's been months and I still no my way around this maze!
And now for the moment of truth... run!

A couple of years ago, we decide to migrate our customer's data from one data center to another, this is the story of how it goes well.
The product was a Facebook canvas and mobile game with 200M users, that represent approximately 500Gibi of data to move stored in MySQL and Redis. The source was stored in Dallas, and the target was New York.
Because downtime is responsible for preventing users to spend their money on our "free" game, we decide to avoid it as much as possible.
In our MySQL main table (manually sharded 100 tables) , we had a modification TIMESTAMP column. We decide to use it to check if a user needs to be copied on the new database. The rest of the data consist of a savegame stored as gzipped JSON in a LONGBLOB column.
A program in Go has been developed to continuously track if a user's data needs to be copied again everytime progress has been made on its savegame. The process goes like this: First the JSON was unzipped to detect bot users with no progress that we simply drop, then data was exported in a custom binary file with fast compressed data to reduce the size of the file. Next, the exported file was copied using rsync to the new servers, and a second Go program do the import on the new MySQL instances.
The 1st loop takes 1 week to copy; the 2nd takes 1 day; a couple of hours for the 3rd, and so on. At the end, copying the latest versions of all the savegame takes roughly a couple of minutes.
On the Redis side, some data were cache that we knew can be dropped without impacting the user's experience. Others were big bunch of data and we simply SCAN each Redis instances and produces the same kind of custom binary files. The process was fast enough to launch it once during migration. It takes 15 minutes because we were able to parallelise across the 22 instances.
It takes 6 months of meticulous preparation. The D day, the process goes smoothly, but we shutdowns our service for one long hour because of a typo on a domain name.1 -
Beware: Here lies a cautionary tale about shared hosting, backups, and -goes without saying- WordPress.
1. Got a call from a client saying their site presented an issue with a third-party add-on. The vendor asked us to grant him access to our staging copy.
2. Their staging copy, apparently, never got duplicated correctly because, for security reasons, their in-house dev changed the name of the wp-content folder. That broke their staging algo. So no staging site.
3. In order to recreate the staging site, we had to reset everything back to WP defaults. Including, for some reason, absolute paths inside the database. A huge fucking database. Because WordPress.
4. Made the changes directly in a downloaded sql file. Shared hosting, obviously, had an upload limit smaller to the actual database.
5. Spent half an hour trying to upload table by table to no avail.
6. In-house uploads a new, fixed database with the help of the shared hosting provider.
7. Database has the wrong path. Again.
8. In-house performs massive Find and Replace through phpMyAdmin on the production server.
9. Obviously, MySQL crashes instantly and the site gets blocked for over 3 hours for exceeding shared hosting limits.
10. Hosting provider refuses to accept this was caused by such a stupid act and says site needs to be checked because queries are too slow.
11. We are gouging our eyeballs as we see an in-house vs. hosting fight unfold. So we decide to watch a whole Netflix documentary in between.
12. Finally, the hosting folds and enables access to the site, which is obvi not working because, you know, wrong paths.
13. Documentary finishes. We log in again, click restore from backup. Go to bed. Client phones to bless us. Client’s in-house dev probably looking for a cardboard box to pack his stuff first thing in the morning. \_(ツ)_/¯ -
So I am currently making an app for a retail franchise and that retail franchise is getting a website done by a company. Since the recipes that the guys want are going to be on the website, the web dev company made a mysql db that has all the recipes.
I thought since the people at the head of the retail franchise have spent time gathering these recipes, I'll just get the data for the app from the db.
I called the project manager for the website up (That's the only contact I got) and asked if they could given me access to the db to use for the app or if I could make a script that would get data from it.
Now this is the part where I tell you I'm only 14 years old and these guys know that because of the head of the retail company.
He puts it on speaker and asks me to say it again and I hear quite a bit of people laughing. I knew what was happening. He asks do you know anything about databases, I explained to him what a db was and how I was going to get the data from it and etc. Half way through me telling him that it would be beneficial for both me and the retail guys, he hung up the call and blocked me.
I asked the head of the retail company if he could ask them about it and he said that he didn't know much about tech so he couldn't ask and if I could find an alternative option.
You might be thinking that the company didn't want to give me permission to access the db which is respectable but they have done this previously as well.
I gave them advice on putting a rewards card feature on the site so the customers could track their points on the site as well as on the app and the PM said "We don't want advice from you."
It has now been 3 weeks on and off because of school where I had to code a ui for the lady at the company to enter all her recipes for the app and waste a lot of time communicating with different people to get all the data.
I hate being disrespected because of my inexperience when I can truly do some extraordinary things with software. 😡😤😣
Its also very hard to find a job being 14.5 -
I'm really not sure. When I was 7-8 years old, I liked to view source in IE, then I somehow managed to use Javascript in the browser. First only some dumb opening of windows. And I liked Batch, so I made some files for copying, backup and stuff.
Then I got to PHP during the years from some online tutorial about making dynamic websites. My website was more static than stone, but yeah, I did page loading with PHP! Awful experience anyway, because I had to install Xampp, get it work and other stuff. 11 years old or so. (and I used Xampp only as a fileserver between laptop and desktop later, because.. PHP4... just no.)
As 12 years old or so I experienced my first World of Warcraft (vanilla) on a custom server in an internet cafe and I thought it's a singleplayer game. When I found out that no, I googled how to make my own server (hated multiplayer back then and loved good games with huge storylines). Failed miserably with ManGOS, got something to work with ArcEMU. There I learned some C++ basic stuff, which I hoped would helped me to fix some bugs. When I opened the code I was like: "Suuure." and left it like that. I learned what a MySQL database is, broke it like four times when I forgot WHERE and still rather played with websites i.e. html, css, js and optionally php when I wanted to repair a webpage for the server. With a friend we managed to get the server work via Hamachi, was fun, the server died too soon. Then I got ManGOS to work, but there wasn't really any interest to make a server anymore, just singleplayer for the lore. (big warcraft fan, don't kick me :D )
I think it was when I was 13y.o. I went to Delphi/Pascal course, which I liked a lot from the beginning, even managed to use my code on old Knoppix via Lazarus(Pascal). At this age I really liked thoae Flash games which were still common to see everywhere. So I downloaded .swfs, opened and tried to understand it. Managed to pull some stuff from it and rewrite in Pascal. Nope, never again that crap.
About the same time I got to Flash files I discovered Java. It was kind of popular back then, so I thought let's give it a try. I liked Flash more. Seriously. I've never seen so much repetitiveness and stupid styling of a code. I had either IDE for compiling C++ or Pascal or notepad! You think I wanted my code kicked all over the place in multiple folders and files? No.
So back to Pascal. I made some apps for my old hobby, was quite satisfied with the result (quiz like app), but it still wasn't the thing. And I really thought I'd like to study CS.
I started to love PHP because of phpBB forums I worked on as 15 y.o. I guess. At the same time I think there was an optional subject at school, again with Pascal. I hated the subject, teacher spoke some kind of gibberish I didn't really understand back then at all and now I find it only as a really stupid explanation of loops and strings.
So I started to hate Pascal subject, but not really the lang itself. Still I wanted something simpler and more portable. Then I got to Python as hm, 17y.o. I think and at the same time to C++ with DevC++. That was time when I was still deciding which lang to choose as my main one (still playing with website, database and js).
Then I decided that learning language from some teacher in a class seriously pisses me off and I don't want to experience it again. I choose Python, but still made some little scripts in C++, which is funny, because Python was considered only as a scripting lang back then.
I haven't really find a cross-platform framework for C++, which would: a) be easy to install b) not require VisualStudio PayForMe 20xy c) have nice license if I managed to make something nice and distribute it. I found Unity3D though, so I played with Blender for models, Audacity for music and C# for code. Only beautiful memories with Unity. I still haven't thought I'm a programmer back then.
For Python however I found Kivy and I was playing with it on a phone for about a year. Still I haven't really know what to do back then, so I thought... I like math, numbers, coding, but I want to avoid studying physics. Economics here I go!
Now I'm in my third year at Uni, should be writing thesis, study hard and what I do? Code like never before, contribute, work on a 3D tutorial and play with Blender. Still I don't really think about myself as a programmer, rather hobby-coder.
So, to answer the question: how did I learn to program? Bashing to shit until it behaved like I desired i.e. try-fail learning. I wouldn't choose a different path.2 -

Yesterday I helped in a college final project. To be done using PHP and MySQL.
- they were taught to create a login page and when submitted just check the values against username and password from DB table and redirect to a dashboard page. No session created.
- in the dashboard, session is not checked. Shows links to other pages.
- each page is a separate php file
- the app allows users to issue books to customers. They were taught to delete the book from book table and save all the info in issue table, when a book is issued
- when a book is returned, book info is saved in a return table and also saved to book table again and deleted from issue table
I asked this student to change it to the right way, to use sessions and includes. He said that then the lecturer would know, he didn't do the project. It's a diploma level course.2 -
Hey all i left my toxic job a few days ago. I am searching for a job now. I had a bad experience after i did a interview task for a company a few days ago. The HR had a google meet session with me before sending me the task. She never mentioned that she wants someone who knows mysql. I finished the task using MERN stack. It was a simple blog app with a simple backend. After i sent the task, the HR messaged me and told me to do the task again using mysql. I was shocked, i told her i didnt know mysql...she ghosted me for a few days and today an hour ago she messaged me and told me that i am rejected...i dont know what to do now...6

I am a Technical Lead in the department in my company that writes code for our clients that have money but doesn't have the technical expertise to handle the complexities of our own software.
Part of my tasks involve taking care of a few projects written by employees that have left after using third-party tools rather than using our own software. No one else in this department knows these third-party tools, they only know our own, and my *still limited* web development experience means I get dumped these things in my lap.
And I'm SO pissed at these projects and their authors and the manager that let these ex-employees write these things. There is this one project that was managed by two different "developers" (I don't know they deserve this title) at two different times, and it is so riddled with different technologies it makes me want to throw up almost daily.
Don't believe me? Here is a complete list of the dependencies listed in the package.json of this project: babel-polyfill, body-parser, cookie-parser, debug, edge, edge-sql, excel-to-json, exceljs, express, html-inline, jade, morgan, mssql, mysql, pug, ramda, request, rotating-file-stream, serve-favicon, webpack, xlsx, xml2js
What this doesn't even show, is that one part of this project (literally one page) is made using react, react-dom, react-redux, and jade. The other part (again literally one page) is made using Angular and Pug. In case you missed it while picking up your jaw, there's also mssql, mysql, edge and edge-sql. excel-to-json, exceljs, xlsx.
Oh you want *more* juicy details? This project takes the entire data object used by the front-end, stringifies it into JSON, and shoves it into the database *as a single field*. And instead of doing WHERE clauses in the SQL queries, it grabs the entire table, loops, parses the json, and does a condition on it. If even one of those JSON entries gets corrupted, the entire solution breaks because these "developers" don't know what try/catch is.
The client asked for a very simple change in their app, which was to add a button that queries the back-end for a URL, shows it in a modal dialog, after which a button is clicked to verify the link by doing a second query to the back-end before modifying a couple of fields in the page.
This. Took. Me. Two. Months*. Save me. Please, save me.
*between constant context switches between this and other projects that were continuously failing because of their mistakes.4 -
I fucked up my MySQL installation...
AGAIN!!
Whenever I really feel like programming in my free time (which became really rare), I fuck something up and spend half of the night fixing it. Once it’s fixed I’m done, don’t wanna do anything anymore..
I should just start programming and set up the infrastructure afterwards.. at least I would get to do some programming then..9 -
so if i get this correctly :
1. mongodb( community server) is going to create some files in my system which will be called "databases/collections/document bullshit via its own special process called mongod (similar to mysql , but ok)
2. my python flask app is going to connect to it via its official driver pymongo (which could be used directly)
3. mongoengine is a library (more of a wrapper on pymongo) providing "easy ways for connecting mongodb via pymongo" (which again could be used directly)
4. flask-mongoengine is library (more of a wrapper on mongoengine providing "easy ways for connecting mongodb via mongoengine via pymongo" (which again could be used directly)
5. flask-pymongo is some another bullshit library/wrapper that took away 6hours of mine which again is "A FUCKING WRAPPER PROVIDING EASY WAYS FOR CONNECTING TO MONGODB VIA PYMONGO"
seriously, fuck web development. Why can't the original driver (i.e pymongo from mongodb devs) could have simpler wrappers? and why does my fucking tutorial instructor had to use the most fucking rarely used flask-mongoengine (which i accidently read as flask-pymongo and got f**ked) to teach newbies? fucking day wasted trying to understand this crap.
I don't like monnopolies, but its somewhat good that the mobile environment is still in the hands of nononsense players like google and oracle(java) . atleast we don't have people releasing wrapper over wrapper over wrapper and then fighting about which wrapper is better to use.
Like , even when devs started cmplaining that android dbs are too difficult to understand, google themselves created an actively supported wrapper that shutted down the fight over which wrapper to use(sqldelight, realm,sql bright etc)5 -
Recent experience:

This is more of an essay than a rant. TLDR at the end. I simply can't choose from all the shitty lecturers I've had, so I'm going to have to go through them one by one. But of background. I'm currently in 7th year of college, I did a multimedia degree in 2 years, a intro course to Software Dev and I'm currently in my final year of my Software Dev degree. So let's start.
Intro Software Course
- we had a database module, which was thought by, I shit you not, the head of the psychology course in the college, she attempted to teach us Databases using access. And not even using SQL, using access GUI components and it's query builder. Need I say more?
1st year software dev
- We had a networking module, the guy that taught the labs, he literally didn't say more than 12 words the entire 12 week semester, his answer to any question you asked him was a grunt and "research it"
- We had a psychology module, I have no fucking idea why, but instead of learning something useful we were told to read this and get in touch with your feelings...
- database module. Yes we actually did SQL here, 12 weeks of select statements and normal form, talked about by a guy in a monotone voice, who sounded like he was contemplating bringing in an assault riffle some day. Also instead of using MySQL he decided to use Ingres. Why I will never know.
2nd Year Software Dev
- We had a module called Algorithms and Data Structures. The lecturer gave us problems she couldn't solve. Simple problems. She was also crazy. Absolutely nuts.
- Object Orientated Programming. I had this lecturer for 3 semesters up until 3rd year. This guy did COBOLT in college, graduated in the 70s or something and went straight into teaching, he taught us Java for nearly 2 years. He literally copied and pasted texts from PDFs and read through them in class. He told myself and another guy at one stage he really didn't care, and was just counting down the days to his retirement.
- Databases again, different lecturer from 1st year, taught us for 2 semesters (24 weeks) and somehow managed to teach us nothing.
3rd Year Software Dev
- software engineering.. This is where the biggest cunt I've ever met was introduced. He arrives into class 15 minutes late every time without fail, talks shit about stuff that has no relevancy to the topic at all, tries to turn everything into a rugby metaphor and every time you ask a question he somehow dodges it and swiftly changes topic. This cunts past profession? A Project Manager. Fucking typical. This dickhead has also thought me 2 other modules.
4th yr Software Dev
- El cunto mentioned above for 2 more modules. Need I say more.
- real time systems, this module took the piss, the module was written by the lecturer which is what earns his space here. Assignments given to us, which required more time to do than we had in labs so we had to work at home, the problem we that is we were using an obscure RTOS called OS9 which would only work on the college computers. When brought to the lecturers attention he just said "figure it out"
Internet of Things - There was 2 lecturers, each lecturer seemingly working off a different plan, one week you'd have one lecturer, the next would be the other one going on about something completely different and unrelated to anything else we'd done.
Some lecturers didn't even make this list as I couldn't be bothered trying to think back about how shit other ones were. These were the ones that always stood out in my mind.
My main take away point from this is that you go to college for the paper which says you have a degree. Learning things that are going to benefit you in a career is up to yourself.
TLDR; 90% of my college lectures were shit. You need to learn useful stuff yourself.1 -
why on earth somebody thought that MySQL on MacOS must be restarted automatically every time you kill it like a fucking zombie?
An why the fuck every time I restart the Mac, I must kill the fucking zombie with a kill -9 in the head 2 or 3 times before being able to access it again?3 -
Forgets mysql password.. hits random common used words got access..
exits..
try to access mysql again and still dont remember which password i used..
.. No forget password option :( -
This happened to me sometime back.
I want to try out a WordPress plugin in my local machine before installing on a production server. It is an Ubuntu machine. Downloaded and installed Xampp, then setup WordPress with MySQL. Now tried uploading the plugin zip file, it throws some permission error, asking to fix permissions or use FTP. I thought of just chmod 777 recursively for the WordPress directory to fix this easily.
Ran the command, looks like it is hung. Terminated using Ctrl+C and then ran the same command. Again it is taking much time. It should not take so much time to recursively change the permission of just a WordPress directory. Thought something was wrong. Before I realized the damage is already done.
Looks like I ran the command
sudo chmod -R 777 /
instead of
sudo chmod -R 777 ./
Fuck, I missed a dot in the command and it is changing permissions of everything in my machine. Saw the System monitor, CPU usage spiked to 100%. I can't close or open any program. Force shutdown the machine using the power key. It didn't boot again. Recovery mode didn't help. Looks like there is no easy way to restore back from this damage. Most of the files I need are backed up in the cloud, still, need a few more personal files so that I can format and reinstall Ubuntu. Realised I have Windows in dual booting. Boot into Windows and used some ext4 reader to recover the files, formatted and reinstalled the OS. Took a few hours to get back to my previous setup.
Lesson Learned: Don't use sudo unnecessarily.
Double check the command while executing.
Running a wrong command with root permission can fuckup your entire machine. -
So I´m still working on that Sync to get rid of this abomination called Wrike.
Now I have a problem.
To be able to sync mantis with our software I need to be able to create projects in mantis through the API.
No problem.
But then again, I need to link custom fields to that just created project.
The mantis API apparently doesn´t have that.
I now have two options:
1. I expose the custom field functions myself on the REST api.
2. I gain direct access to the mysql database and do it within my sync job in the database.
Well I´m not a web developer. Like, at all.
But I thought: Hey how hard can it be?
So I got an Apache server with php, mysql and XDebug running with VSCode.
Works better than expected.
But now that I have actually seen the mantis code, I´m seriously considering number 2 again...
Fucking php... -
I'd like to dive deep into web development.
I'm creating a little tool for myself on a web page, including server-side php, css, html, mysql and jquery, all just for fun and the experience.
I've got several ideas on how I want this tool to work and behave ...
But it's fucking difficult to wrap my head around all those technologies available. I don't know how to achieve certain things (yet) and what even to look out for😣
Fun fact: I already experimented with HTML, CSS, jQuery before as a noob. Yet today I've forgotten almost everything and need to start almost all over again, now even including PHP and MySQL, too.
This is gonna be fine. 😐 -
Working for a company using Cobol > CGI > PHP > MySQL > Django, and once again another custom rolled framework with no documentation in PHP. Basically no desire, haha.

Me, trying to access an old mysql database on a Linux server, the root user gets rejected. Out of frustration I delete mysql entirely and try to start again.
I was not using sudo to access the root user...
In the bright side, the deleted mysql version was actually an old one, the database is actually fine.1 -
I got situation here,
I am getting 524 error from cloud fare. I sent some data using AJAX, process it and then return the result. Since the data is large and have some SQL manipulation on it so it take a lot of time. I put the process in back end. But still even for 10k records it took 4-5 minutes to process, Issue is everything works fine but since cloud fare response time is 1-2 minute so it through 524 error (as it does not getting any response within its time frame). How I am suppose to tackle this. May be using job scheduler now ? My client simply refuse to send small data. My Friend is suggesting don't use ajax, simply reload the page. But again data is too much so page loading will also through 524 error. Kindaa stuck here. Any idea/suggestion how I can proceed.
Language I am using PHP. Database, MySQL and SQL.
Hmm Here is some more explanation

But not working

MySQL docker container randomly just redeployed itself. Because he can.
The worst part is that it pulled the last mysql-percona image (5.7 strict mode by default plus more) and I cant revert it!!! looooool
And you know what its the best thing? is that today is friday!! Best weekend ever 10/10 would repeat again fixing sql's everyday2 -
So, I am in the last stages of development of a really big project and I need to figure out a way to package future patches and updates for the client in order for them to manually update the project on prod server.
For reasons I cannot specify here, they will not use any automated process, and we need to provide regular patches and updates for the next year.
So I was thinking of using git archive to package changed files from our repo for every new commit, or series of commits, and just give them that, along with any database schema updates as sql files (again, no automation can be used).
We are talking about a large PHP + MySQL app, and cannot use automated deployment strategies.
I feel there must be a better way to do this, but this is the best I could come up with so far.
What do you people think?
Any ideeas? -
I once started developing a chatbot, super easy and simple, a MySQL backend for the QA stuff.
I then started to think on the most modular way to "reuse" the same QA system, and got stuck on it for around 3 days (while doing other things).
Obviously the chatbot stuff could'nt leave my thoughts , and I remember it was a saturday morning, I woke up super excited and just started writing down what my sleepy me was engineering while I was dreaming.
I still have the same system implemented and I'm expecting that some day, in the future, I'll have to rewrite it, and I hope "sleepy-me" helps me again, this time with an actual interesting solution haha
