Finally finished my electric longboard, extremely pleased with the end result.

Did some tests with it, 30km range and +-40km/h top speed

I have this little hobby project going on for a while now, and I thought it's worth sharing. Now at first blush this might seem like just another screenshot with neofetch.. but this thing has quite the story to tell. This laptop is no less than 17 years old.

So, a Compaq nx7010, a business laptop from 2004. It has had plenty of software and hardware mods alike. Let's start with the software.

It's running run-off-the-mill Debian 9, with a custom kernel. The reason why it's running that version of Debian is because of bugs in the network driver (ipw2200) in Debian 10, causing it to disconnect after a day or so. Less of an issue in Debian 9, and seemingly fixed by upgrading the kernel to a custom one. And the kernel is actually one of the things where you can save heaps of space when you do it yourself. The kernel package itself is 8.4MB for this one. The headers are 7.4MB. The stock kernels on the other hand (4.19 at downstream revisions 9, 10 and 13) took up a whole GB of space combined. That is how much I've been able to remove, even from headless systems. The stock kernels are incredibly bloated for what they are.

Other than that, most of the data storage is done through NFS over WiFi, which is actually faster than what is inside this laptop (a CF card which I will get to later).

Now let's talk hardware. And at age 17, you can imagine that it has seen quite a bit of maintenance there. The easiest mod is probably the flash mod. These old laptops use IDE for storage rather than SATA. Now the nice thing about IDE is that it actually lives on to this very day, in CF cards. The pinout is exactly the same. So you can use passive IDE-CF adapters and plug in a CF card. Easy!

The next thing I want to talk about is the battery. And um.. why that one is a bad idea to mod. Finding replacements for such old hardware.. good luck with that. So your other option is something called recelling, where you disassemble the battery and, well, replace the cells. The problem is that those battery packs are built like tanks and the disassembly will likely result in a broken battery housing (which you'll still need). Also the controllers inside those battery packs are either too smart or too stupid to play nicely with new cells. On that laptop at least, the new cells still had a perceived capacity of the old ones, while obviously the voltage on the cells themselves didn't change at all. The laptop thought the batteries were done for, despite still being chock full of juice. Then I tried to recalibrate them in the BIOS and fried the battery controller. Do not try to recell the battery, unless you have a spare already. The controllers and battery housings are complete and utter dogshit.

Next up is the display backlight. Originally this laptop used to use a CCFL backlight, which is a tiny tube that is driven at around 2000 volts. To its controller go either 7, 6, 4 or 3 wires, which are all related and I will get to. Signs of it dying are redshift, and eventually it going out until you close the lid and open it up again. The reason for it is that the voltage required to keep that CCFL "excited" rises over time, beyond what the controller can do.

So, 7-pin configuration is 2x VCC (12V), 2x enable (on or off), 1x adjust (analog brightness), and 2x ground. 6-pin gets rid of 1 enable line. Those are the configurations you'll find in CCFL. Then came LED lighting which required much less power to run. So the 4-pin configuration gets rid of a VCC and a ground line. And finally you have the 3-pin configuration which gets rid of the adjust line, and you can just short it to the enable line.

There are some other mods but I'm running out of characters. Why am I telling you all this? The reason is that this laptop doesn't feel any different to use than the ThinkPad x220 and IdeaPad Y700 I have on my desk (with 6c12t, 32G of RAM, ~1TB of SSDs and 2TB HDDs). A hefty setup compared to a very dated one, yet they feel the same. It can do web browsing, I can chat on Telegram with it, and I can do programming on it. So, if you're looking for a hobby project, maybe some kind of restrictions on your hardware to spark that creativity that makes code better, I can highly recommend it. I think I'm almost done with this project, and it was heaps of fun :D

!Story

The day I became the 400 pound Chinese hacker 4chan.

I built this front-end solution for a client (but behind a back end login), and we get on the line with some fancy European team who will handle penetration testing for the client as we are nearing dev completion.

They seem... pretty confident in themselves, and pretty disrespectful to the LAMP environment, and make the client worry even though it's behind a login the project is still vulnerable. No idea why the client hired an uppity .NET house to test a LAMP app. I don't even bother asking these questions anymore...

And worse, they insist we allow them to scrape for vulnerabilities BEHIND the server side login. As though a user was already compromised.

So, I know I want to fuck with them. and I sit around and smoke some weed and just let this issue marinate around in my crazy ass brain for a bit. Trying to think of a way I can obfuscate all this localStorage and what it's doing... And then, inspiration strikes.

I know this library for compressing JSON. I only use it when localStorage space gets tight, and this project was only storing a few k to localStorage... so compression was unnecessary, but what the hell. Problem: it would be obvious from exposed source that it was being called.

After a little more thought, I decide to override the addslashes and stripslashes functions and to do the compression/decompression from within those overrides.

I then minify the whole thing and stash it in the minified jquery file.

So, what LOOKS from exposed client side code to be a simple addslashes ends up compressing the JSON before putting it in localStorage. And what LOOKS like a stripslashes decompresses.

Now, the compression does some bit math that frankly is over my head, but the practical result is if you output the data compressed, it looks like mandarin and random characters. As a result, everything that can be seen in dev tools looks like the image.

So we GIVE the penetration team login credentials... they log in and start trying to crack it.

I sit and wait. Grinning as fuck.

Not even an hour goes by and they call an emergency meeting. I can barely contain laughter.

We get my PM and me and then several guys from their team on the line. They share screen and show the dev tools.

"We think you may have been compromised by a Chinese hacker!"

I mute and then die my ass off. Holy shit this is maybe the best thing I've ever done.

My PM, who has seen me use the JSON compression technique before and knows exactly whats up starts telling them about it so they don't freak out. And finally I unmute and manage a, "Guys... I'm standing right here." between gasped laughter.

If only it was more common to use video in these calls because I WISH I could have seen their faces.

Anyway, they calmed their attitude down, we told them how to decompress the localStorage, and then they still didn't find jack shit because i'm a fucking badass and even after we gave them keys to the login and gave them keys to my secret localStorage it only led to AWS Cognito protected async calls.

Anyway, that's the story of how I became a "Chinese hacker" and made a room full of penetration testers look like morons with a (reasonably) simple JS trick.

A room full of mostly old male stressed out engineers sat in chairs, and the presenter said:

"So who watched Judging Amy last night?"

The presenter went on to express her surprise that nobody in the room had seen last night's episode of Judging Amy.... and wasn't going to drop the topic.

The meeting, if it ever had any, now had no chance of going anywhere good.

By the end of the meeting someone would walk out and "retire" shortly there after, and it certainly wasn't going to be the presenter....

Backstory:

The company built on the IBM model of sell pricey custom hardware (granted it worked really well) and sell expensive support contracts wasn't doing as well as it had hoped. Granted it was still doing better than most of its neighboring companies, but it was clear that with the .com bust the days of catered lunches every day were over.

The company had grown fat and everyone knew that while the company had a good enough product(s) to survive, there weren't enough lifeboats for everyone to survive.

In the midst of this an HR department that took up nearly 20% of the office space at HQ felt it needed to justify its existence / expenses.

They decided to do this in the same way they always had, by taking funding from other departments, this time not by simply demanding more direct budgets for themselves.... they decided to impose mandatory 'training' on other departments ... that they would then bill for this training.

When HR got wind that there were some stressed out engineers the solution was, as it always is for HR.... to do more HR stuff:

They decided to take these time starved engineers away from their jobs, and put them in a room with HR for 4 days. Meanwhile the engineer's tasks, deadlines and etc remained the same.

Support got roped into it too, and that's how I ended up there.

It would be difficult to describe the chasm between HR and everyone else at that company. This was an HR department that when they didn't have enough cubes (because of constant remodeling in the HR area under the guise of privacy) sat their extra HR employees next to engineering and were 'upset' that the engineers 'weren't very friendly and all they did was work'.

At one point a meeting to discuss this point of contention was called off for some made up reason or another by someone with a clue.

So there we all sat, our deadlines kept ticking away and this HR team (3 people) stood at the front of the room and were perplexed that none of these mostly older males in this room had seen last night's episode of Judging Amy.

From there the presentation was chaos, because almost the entire thing was based on your knowledge of what happened to poor stressed out Amy ... or something like that.

We were peppered with HR tales of being stressed out and taking a long lunch and feeling better, and this magical thing where the poor HR person went and had a good cry with her boss and her boss magically took more off her plate (a brutal story where the poor HR person was almost moved to tears again).

The lack of apparent sympathy (really nobody said much at all) and lack of seeming understanding from the crowd of engineers that all they should do is take a long lunch, or tell their boss to solve their problems ... seemed to bother the HR folks. They were on edge.

So then they finally asked "What are your stressers?" And they picked the worst possible person they could to ask, Ted.

Ted was old, he prickly, he was the only one who understood the worst ass hell of assembly that had been left behind.

Ted made a mistake, he was honest with folks who couldn't possibly understand what he was saying. "This mandatory class is stressing me out. I have work to do and less time because of this class."

The exchange that followed was kinda horrible and I recall sitting behind Ted trying to be as small as possible as to not be called on. Exactly what everyone said almost doesn't matter.

A pedantic debate between Ted and the HR staff about "mandatory" and "required" followed. I will just sum it up that they were both in the wrong for how they behaved for a good 20 minutes...

Ted walked out, and would later 'retire' that week.

Ted had a history and was no saint. I suspect an email campaign by various folks who recounted the events that day spared ted the 'fired' status and he walked with what eventually would become the severance package status quo.

HR never again held another 'training', most of them would all finally face the axe a few months later after the CEO finally decided that 'customer facing, and product producing' headcount had been reduced enough ... and it was other internal staff's time for that.

The result of the meeting was one less engineer, and everyone else had 4 days less of work done...

(Not dev, not rant, although it might become one later on)

So as some of you may know, I am colorblind. I always avoid working with colors because of it. Yesterday I decided to do something I've always wanted, painting. And no I don't mean painting on a canvas but miniatures and other 3D models.

I love catan, I love 3D printing and I thought let's print a catan set and paint it myself, without depending on family to ask for colors.
I've got this German paint tubes and used the wikipedia color descriptions to decide what to paint which color.

The following is the result, its a wheat tile (and in the background a wood tile).
Feel free to give tips and suggestions. If I picked a wrong color please tell me so I can update my tactics.

Finally took this step. Yay

(Written March 13th at 2am.)

This morning (yesterday), my computer decided not to boot again: it halts on "cannot find firmware rtl-whatever" every time. (it has booted just fine several times since removing the firmware.) I've had quite the ordeal today trying to fix it, and every freaking step along the way has thrown errors and/or required workarounds and a lot of research.

Let's make a list of everything that went wrong!

1) Live CD: 2yo had been playing with it, and lost it. Not easy to find, and super smudgy.

2) Unencrypt volume: Dolphin reports errors when decrypting the volume. Research reveals the Live CD doesn't incude the cryptsetup packages. First attempts at installing them mysteriously fail.

3) Break for Lunch: automatic powersaving features turned off the displays, and also killed my session.

4) Live CD redux: 25min phonecall from work! yay, more things added to my six-month backlog.

5) Mount encrypted volume: Dolphin doesn't know how, and neither do I. Research ensues. Missing LVM2 package; lvmetad connection failure ad nauseam; had to look up commands to unlock, clone, open, and mount encrypted Luks volume, and how to perform these actions on Debian instead of Ubuntu/Kali. This group of steps took four hours.

6) Chroot into mounted volume group: No DNS! Research reveals how to share the host's resolv with the chroot.

7) `# apt install firmware-realtek`: /boot/initrd.img does not exist. Cannot update.

8) Find and mount /boot, then reinstall firmware: Apt cannot write to its log (minor), listed three install warnings, and initially refused to write to /boot/initrd.img-[...]

9) Reboot!: Volume group not found. Cannot process volume group. Dropping to a shell! oh no..

(Not listed: much research, many repeated attempts with various changes.)

At this point it's been 9 hours. I'm exhausted and frustrated and running out of ideas, so I ask @perfectasshole for help.
He walks me through some debugging steps (most of which i've already done), and we both get frustrated because everything looks correct but isn't working.

10) Thirteenth coming of the Live CD: `update-initramfs -u` within chroot throws warnings about /etc/crypttab and fsck, but everything looks fine with both. Still won't boot. Editing grub config manually to use the new volume group name likewise produces no boots. Nothing is making sense.

11) Rename volume group: doubles -'s for whatever reason; Rebooting gives the same dreaded "dropping to a shell" result.

A huge thank-you to @perfectasshole for spending three hours fighting with this issue with me! I finally fixed it about half an hour after he went to bed.

After renaming the volume group to what it was originally, one of the three recovery modes managed to actually boot and load the volume. From there I was able to run `update-initramfs -u` from the system proper (which completed without issue) and was able to boot normally thereafter.

I've run updates and rebooted twice now.
After twelve+ hours... yay, I have my Debian back!

oof.

Man I really need to get this off my chest. So here goes.
I just finished 1 year in corporate after college. When I joined, the team I got was brilliant, more than what I thought I would get. About 6 months in, the project manager and lead dev left the company. Two replacements took their place, and life's been hell ever since.

The new PM decided it was his responsibility to be our spokesperson and started talking to our overseas manager (call her GM) on our behalf, even in the meetings where we were present, putting words in our mouth so that he's excellent and we get a bad rep.

1 month in, GM came to visit our location for a week. She was initially very friendly towards all of us. About halfway through the week, I realized that she had basically antagonized the entire old team members. Our responsibilities got redistributed and the work I was set to do was assigned to the new dev (call her NR).

Since then, I noticed GM started giving me the most difficult tasks and then criticizing my work extra hard, and the work NR was doing was praised no matter what. I didn't pay much attention to it at first, but lately the truth hit me hard. I found out a fault in NR's code and both PM and GM started saying that because I found it, it was my responsibility to fix it. I went through the buggy code for hours and fixed it. (NR didn't know how it worked, because she had it written by the lead dev and told everyone she wrote it).

I found out lately that NR and PM got the most hike, because they apparently "learnt" new tech (both of them got their work done by others and hogged the credit).They are the first in line to go onsite because they've been doing 'management work'. They'd complained to GM during her visit that we were not friendly towards them. And from that point on if anything went wrong, it would be my fault, because my component found it out (I should mention that my component mostly deals with the backend logic, so its pretty adept at finding code leaks).

What broke my patience is the fact that lately I worked my ass off to deliver some of the best code I'd written, but my GM said in front of the entire team that at this point "I'm just wasting money". She's been making a bad example out of me for some time, but this one took the cake. I had just delivered a promising result in a task in 1 week that couldn't be done by my PM in 4 weeks, and guess what? "It's not good enough". No thank you, no appreciation, nothing. Finally, I decided I'd had enough of it and started just doing tasks as I could. I'd do what they ask, but won't go above and beyond my way to make it perfect.

My PM realized this and then started pushing me harder. Two days back, I sent a mail to the team with GM in cc exposing a flaw in the code he had written, and no one bothered to reply (the issue was critical). When I asked him about it, he said "How can you expect me to reply so soon when it's already been told that when anything happens we should first resolve within the team and then add GM in the loop?" I realized it was indeed discussed, but the issue was extremely urgent, so I had asked everyone involved, and it portrayed him in a bad light. I could've fixed it, but I didn't because on the off chance if it broke something, they'd start telling me that I broke the tool, how its my fault and how its a critical issue I have to fix ASAP, etc. etc., you get the idea.

Can anyone give me some advice of how to deal with this kind of situation? I would have left but with this pandemic going on, market being scarce and the fact that I'm only experienced by 1 year, I don't think I qualify for a job switch just now.

Why does CSS never work the way you'd expect? All I want to do is align something to the bottom of a div. No. Will not happen. You'd think it might be something simple as 'v-align' or 'align: bottom' or 'fucking put it at the bottom: now;'

No, it's never that simple. I try every result I can find from googling. Nothing. Simply does not work.

How about trying to keep a div to a square when you resize the page? That should be simple? height = width right? Fuck you. Ha hahah, no you have to implement some horrendous arcane hack involving fake elements and other bullshit.

You finally fix one thing and everything else you had working is now broken.

...and then some fuckwit comes along and goes "Oh, CSS isn't hard..." and it takes everything you have not to beat them to death with your rubber duck.

What the hell is wrong with CSS? It's not even programming! It's just pure, sadistic hell! FUCK CSS!!!!

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 :/

Ok friends let's try to compile Flownet2 with Torch. It's made by NVIDIA themselves so there won't be any problem at all with dependencies right?????? /s

Let's use Deep Learning AMI with a K80 on AWS, totally updated and ready to go super great always works with everything else.

> CUDA error
> CuDNN version mismatch
> CUDA versions overwrite
> Library paths not updated ever
> Torch 0.4.1 doesn't work so have to go back to Torch 0.4
> Flownet doesn't compile, get bunch of CUDA errors piece of shit code
> online forums have lots of questions and 0 answers
> Decide to skip straight to vid2vid
> More cuda errors
> Can't compile the fucking 2d kernel
> Through some act of God reinstalling cuda and CuDNN, manage to finally compile Flownet2
> Try running
> "Kernel image" error
> excusemewhatthefuck.jpg
> Try without a label map because fuck it the instructions and flags they gave are basically guaranteed not to work, it's fucking Nvidia amirite
> Enormous fucking CUDA error and Torch error, makes no sense, online no one agrees and 0 answers again
> Try again but this time on a clean machine
> Still no go
> Last resort, use the docker image they themselves provided of flownet
> Same fucking error
> While in the process of debugging, realize my training image set is also bound to have bad results because "directly concatenating" images together as they claim in the paper actually has horrible results, and the network doesn't accept 6 channel input no matter what, so the only way to get around this is to make 2 images (3 * 2 = 6 quick maths)
> Fix my training data, fuck Nvidia dude who gave me wrong info
> Try again
> Same fucking errors
> Doesn't give nay helpful information, just spits out a bunch of fucking memory addresses and long function names from the CUDA core
> Try reinstalling and then making a basic torch network, works perfectly fine
> FINALLY.png
> Setup vid2vid and flownet again
> SAME FUCKING ERROR

> Try to build the entire network in tensorflow
> CUDA error
> CuDNN version mismatch
> Doesn't work with TF
> HAVE TO FUCKING DOWNGEADE DRIVERS TOO
> TF doesn't support latest cuda because no one in the ML community can be bothered to support anything other than their own machine
> After setting up everything again, realize have no space left on 75gb machine
> Try torch again, hoping that the entire change will fix things

At this point I'll leave a space so you can try to guess what happened next before seeing the result.

Ready?

> SAME FUCKING ERROR

In conclusion, NVIDIA is a fucking piece of shit that can't make their own libraries compatible with themselves, and can't be fucked to write instructions that actually work.

If anyone has vid2vid working or has gotten around the kernel image error for AWS K80s please throw me a lifeline, in exchange you can have my soul or what little is left of it

First time rant here, and I'm just gonna let fucking loose because this seems to be a good place for it.

My uni can't teach programming for shit. It's the reason people sign up for the course. They want to know how to program. I'm self-taught and unhappy in college as it is.

I joined CS because I thought they'd assimilate work in the real world, which is experience I need. I realized early on that programming is like art, and I love the rush I get of something finally working right.

That said, they sucked the fun out of it. It's too structured. Everyone trying to get the same goddamn result. In the real world, we'd be working on a larger project that involved planning, design, communication, teamwork, and the ability to complete each of our own pieces of the puzzle and subsequently put them together in a project that works for the end user.

I'm paying to be a fucking sheep, people. Why do employers give a shit about a degree instead of talent? Welp, fuck society for this. You can tell me I can drop it and still get a good job, it'll just be harder. That's the fucking problem. I can't get a job if these incompetent fucking bastards will throw out my resumé the moment they see "self-taught."

If we could hire based on GitHub contributions, I think many of us here would be relatively better off. Programmers program, not socialize. We do socialize, but in our own little groups. We team up as needed. The moment the jackass in HR realizes that, the better off we'll be.

Sorry, just the way I'm seeing shit right now. I'm going through some OCD-induced depression and this might be a result of that, but I'm passed the point of giving a fuck.

Jesus christ what is wrong with this one

12: Colleague deploys something to production (with a second pair of eyes)
14: Asks me why other team isn't seeing the result, I ask whether they have monitored the logs, they have not
17: They finally read the logs and find the problem, change window has ended so tomorrow there's another attempt

Today, they deployed again around 10 and then went away because they had some private responsibilities. Never looked at the logs, never bothered to verify if anything still worked. Just dropped it in a chat.

10 years older than I am, how can you be so irresponsible

Got fed up with having to use the mouse/trackpad while editing code or using the terminal, so I decided to (finally) learn proper vim keybindings and tmux.

Boooooy oh boy, this certainly changes things.

I think I'm in love with tmux. Damn that piece of software is so sexy. Disabled the mouse, propped up my dotfiles and installed tmux + my conf on all machines I use. It's so useful, so fast and so pretty...

Spent some time with vimtutor too. Finally getting faster with the keybindings. Installed neovim, got some plug-ins (nerdtree, fzf etc), disabled the mouse and arrow keys, and made it pretty. It's actually pretty nice, but I'm not at the "buff gorilla who took speed and pressed 24 keys in a microsecond" typing level yet. One day though.

Also I'm using the Nord color scheme on everything. Overall pretty satisfied with the end result. Still not as productive as I was with VS Code, but I think I'll eventually surpass my previous productivity levels.

If anyone has any tips for vim/nvim or tmux, feel free to share!

I spent two weeks writing a WordPress plugin to take some form data, process it through another website, and take the result to Salesforce. the client had a "Salesforce specialist" doing everything on the Salesforce side and refused to give me access to see if the data was properly pushed through.

Finally I got it in working condition when suddenly it stopped working, I hadn't changed anything since it worked so I asked if he could have possibly changed something. We argued for over 4 hours about who changed something, the whole time I was looking for the error in my code. At 6pm I finally told him I would need to take a look at it tomorrow.

Overnight he sent me an email:
"Hey, sorry about the confusion yesterday, I set Salesforce to deny duplicate email entries, looks like once I removed that everything is working."

3:40 in the morning... Finally set up most of the basic of Arch with i3. Been more than 12 hours... My eyes r dying... And so m I... Kinda swollen arteries near side of the head coz of overload...
And I have college tomorrow... Or today... Watever 😭😭😭

NO. NO. A THOUSAND TIMES: NO.

I clicked on this out of genuine curiosity to see if someone was finally trying to discourage people from annoying the shit out of website visitors. A summary of the suggestions in their article as to what to use popups for:

1. Announce new products/services, features, policy updates, new blog posts
2. Promote your sales or coupons (including countdowns)
3. Encourage people to input their e-mail address / subscribe, perhaps also offering some vague thing they will get as a reward for doing so
4. Contact forms (e.g. support etc.)
5. Prompt visitors to confirm their age before showing content
6. Login/register forms
7. Display social media "share" buttons when a visitor has scrolled a certain way through the page content.
8. Display cookie consent prompt.
9. Help guide visitors to the part of the website they want to go to.

Of these: 1, 2, 3, and 7 need to die for sure. If a website does any of these things I'm inclined to immediately leave and never return. 8 is a little annoying but seems a necessity.

Someone even replied to the Tweet saying that popups are annoying, the company responded with "let's change that!"

Blank portions of the screenshot are to avoid promoting the company unintentionally as a result of the rant ;)

How I got selected for GSoC'19:
I will describe my journey from detail i.e from the 1st year of the college. I joined my college back in 2017 (July), I was not even aware of Computer Science. What are the different languages of CS, but I had a strong intuition of doing BTech from CSE only?

So yeah I was totally unaware of the computer science stuff, but I had a strong desire to learn it and I literally don’t know why I had this desire. After getting into college, I was learning HTML, Python, and C, also I am really thankful to my friends who really helped me to learn, building logic and making stuff out of it. During the 1st month of joining the college, I got to know what is Open Source, GSoC, Github due to my helpful seniors. But I was not into Open Source during my 1st year of college as I thought it is very difficult to start. In my 1st year, I used to do competitive programming and writing scripts in Python to automate various stuff. I never thought that I would even start doing Open Source development, also in the summer vacations after the 1st year I used to practice programming on HackerRank and learnt an awesome course called Automate the Boring Stuff with Python(which I think is one of the most popular courses for Python) which really helped me to build by Python skills.

Now the 2nd year came, I was totally confused between doing Open Source development or continue with my Competitive programming. But I wanted to know about Open Source development, so I thought to start now will be a good idea. I started attending meetups of OSDC(Open Source Developers Club) which is a hub of my college, which really helped me to know more about Open Source development from my seniors. I started looking for beginner friendly projects in Python on the website Up For Grabs, it’s really helpful for the beginners. So I contributed in a few of them, and in starting it was really tough for me but yeah I continued, which really helped me to at least dive into Open Source. Now I thought to start contributing in any bigger project, which has millions of lines of code which will be really interesting. So I started looking for the project, as I was into web development those days so I thought to find a project which matches my domain. So yeah I finally landed on Oppia:
Oppia

I started contributing into Oppia in November, so yeah in starting it was really difficult for me to solve any issue (as I wasn’t aware of the codebase which was really big), but yeah mentors at Oppia are really helpful, they guided me which really helped me to start my journey with Oppia. By starting of January I was able to resolve around 3–4 issues, which helped me to become the collaborator at Oppia, afterward I really liked contributing to it and I was able to resolve around 9–10 issues by the end of February, which landed me to become a Team Member at Oppia which was really a confidence boost and indication for me that I am in the right direction.

Also in February, the GSoC organizations list was out, and yeah Oppia was also participating in it. The project ideas of Oppia were really interesting, I became even confused to pick anyone because there were 4–5 ideas which seemed interesting to me. After 1–2 days of thought process I decided to go for one of them, i.e “Asking students why they picked a particular answer”, a full stack project.

I started making proposals on it, from the first week of March. I used to get my proposal reviewed frequently from the mentors, which really helped me to build a good and strong proposal.

I must say a well-defined proposal is the most important key for getting selected in GSoC, also you must have done some contributions to the organization earlier which I think really maximize your chances of selection in GSoC.

So after my proposal was made, I submitted it on the GSoC website.
Result Day:

It was the result day, by the way, I had the confidence of being selected, but yeah I was a little bit nervous. All my friends were asking when is your result coming, I told them it will come at 12.30AM (IST). Finally, the time came when I refreshed the GSoC website, Voila the results were out. I opened the Oppia organization page, and yeah my name was there. That was the day I was really happy and satisfied, I was thinking like I have achieved something in my life. It was a moment of pleasure for me, I called my parents and told them my result, they were really happy for me.

I say cracking GSoC is worth it, the preparation you do, the contributions you do, the making of the proposal is really worth.

I got so many messages from my juniors, friends, and seniors, they congratulated me. After that when I uploaded my result of Facebook and LinkedIn, there were tons of comments and likes on the post. So yeah that’s my journey.

By the way, I am writing this post after really late, sorry for it. I must have done it earlier, but due to milestone 1 of GSoC, I was busy.

So ok here it is, as asked in the comments.

Setting: customer (huge electronics chain) wants a huge migration from custom software to SAP erp, hybris commere for b2b and ... azure cloud
Timeframe: ~10 months….

My colleague and me had the glorious task to make the evaluation result of the B2B approval process (like you can only buy up till € 1000, then someone has to approve) available in the cart view, not just the end of the checkout. Well I though, easy, we have the results, just put them in the cart … hmm :-\
The whole thing is that the the storefront - called accelerator (although it should rather be called decelerator) is a 10-year old (looking) buggy interface, that promises to the customers, that it solves all their problems and just needs some minor customization. Fact is, it’s an abomination, which makes us spend 2 months in every project to „ripp it apart“ and fix/repair/rebuild major functionality (which changes every 6 months because of „updates“.

After a week of reading the scarce (aka non-existing) docs and decompiling and debugging hybris code, we found out (besides dozends of bugs) that this is not going to be easy. The domain model is fucked up - both CartModel and OrderModel extend AbstractOrderModel. Though we only need functionality that is in the AbstractOrderModel, the hybris guys decided (for an unknown reason) to use OrderModel in every single fucking method (about 30 nested calls ….). So what shall we do, we don’t have an order yet, only a cart. Fuck lets fake an order, push it through use the results and dismiss the order … good idea!? BAD IDEA (don’t ask …). So after a week or two we changed our strategy: create duplicate interface for nearly all (spring) services with changed method signatures that override the hybris beans and allow to use CartModels (which is possible, because within the super methods, they actually „cast" it to AbstractOrderModel *facepalm*).
After about 2 months (2 people full time) we have a working „prototype“. It works with the default-sample-accelerator data. Unfortunately the customer wanted to have it’s own dateset in the system (what a shock). Well you guess it … everything collapsed. The way the customer wanted to "have it working“ was just incompatible with the way hybris wants it (yeah yeah SAP, hybris is sooo customizable …). Well we basically had to rewrite everything again.
Just in case your wondering … the requirements were clear in the beginning (stick to the standard! [configuration/functinonality]). Well, then the customer found out that this is shit … and well …

So some months later, next big thing. I was appointed technical sublead (is that a word)/sub pm for the topics‚delivery service‘ (cart, delivery time calculation, u name it) and customerregistration - a reward for my great work with the b2b approval process???

Customer's office: 20+ people, mostly SAP related, a few c# guys, and drumrole .... the main (external) overall superhero ‚im the greates and ur shit‘ architect.
Aberage age 45+, me - the ‚hybris guy’ (he really just called me that all the time), age 32.
He powerpoints his „ tables" and other weird out of this world stuff on the wall, talks and talks. Everyone is in awe (or fear?). Everything he says is just bullshit and I see it in the eyes of the others. Finally the hybris guy interrups him, as he explains the overall architecture (which is just wrong) and points out how it should be (according to my docs which very more up to date. From now on he didn't just "not like" me anymore. (good first day)
I remember the looks of the other guys - they were releaved that someone pointed that out - saved the weeks of useless work ...

Instead of talking the customer's tongue he just spoke gibberish SAP … arg (common in SAP land as I had to learn the hard way).
Outcome of about (useless) 5 meetings later: we are going to blow out data from informatica to sap to azure to datahub to hybris ... hmpf needless to say its fucking super slow.
But who cares, I‘ll get my own rest endpoint that‘ll do all I need.

First try: error 500, 2. try: 20 seconds later, error message in html, content type json, a few days later the c# guy manages to deliver a kinda working still slow service, only the results are wrong, customer blames the hybris team, hmm we r just using their fucking results ...
The sap guys (customer service) just don't seem to be able to activate/configure the OOTB odata service, so I was told)
Several email rounds, meetings later, about 2 months, still no working hybris integration (all my emails with detailed checklists for every participent and deadlines were unanswered/ignored or answered with unrelated stuff). Customer pissed at us (god knows why, I tried, I really did!). So I decide to fly up there to handle it all by myself

A little late but whatever.

About half a year ago, I started working on setting up self hosted (slippy) maps. For one, because of privacy reasons, for two, because it'd be in my own control and I could, with enough knowledge, be entirely in control of how this would work.

While the process has been going on for hours every day for about half a year (with regular exceptions), I'll briefly lay out what I've accomplished.

I started with the OpenMapTiles project and tried to implement it myself. This went well but there were two major pitfalls:
1. It worked postgres database based. This is fine but when you want to have the entire world.... the queries took insanely long (minutes, at lower zoom levels) and quite intimate postgres/tooling knowledge was required, which I don't have.
2. Due to the long queries and such, the performance was so bad that the maps could take minutes to render and when you'd want that in production... yeah, no.

After quite some time I finally let that idea sail and started looking into the MBTiles solution; generating sqlite databases of geojson features. Very fast data serving but the rendering can take quite some time.

After some more months, I finally got the hang of it to the point that I automated 50-70 percent of the entire process. The one problem? It takes a shitload of resources and time to generate a worldwide mbtiles database.
After infinite numbers of trial and error, I figured out that one can devide a 'render' (mbtiles aka sqlite database) into multiple layers (one for building data, one for water, one for roads and so on), so I started doing renders that way.
Result? Styling became way more easy and logical and one could pick specific data to display; only want to display the roads? Its way more simple this way. (Not impossible otherwise but figuring out how that works... Good luck).

Started rendering all the countries, continents and such this way and while this seemed like a great idea; the entire world is at 3-4 percent after about a month. And while 40-70 percent generates 10 times as fast, that's still way too slow.

Then, I figured out that you can fetch data per individual layer/source. Thus, I could render every layer separately which is way faster.

Tried that with a few very tiny datasets and bam, it works. (And still very fast).

So, now, I'm generating all layers per continent. I want to do it world based but figured out that that's just not manageable with my resources/budget.

Next to that, I'm working on an API which will have exactly the features I want/need!

I've made the json protocol. It's a protocol containing only json. No http or anything.

To parse an json object from a stream, you need a function that returns the length of the first object/array of all your received data. The result of that function is to get the right chunk of the json to deserialize.

For such function, json needs to be parsed, so I wrote that function in C to be used with my C server and Python client. I finally implemented a C function into python function that has a real benefit / use case. Else you had to validate but by bit by the python json parser and that's slow while streaming. Some messages are quite big.

Advantage of this protocol is that it's full duplex.

I'm very happy!

so after several hours of irritated detective work, I've finally found out what is the thing that periodically, every about 10-15 seconds, starts two PowerShell processes which run for about a second or two and during that time take about 20% of my CPU capacity...

They're being launched from a commandline, to do GetPackages with name of OmenLightStudio, and the result is then piped into find.exe to find InstallLocation part.

...for whatever reason.
and this is done every 10 seconds by... *drumroll*
HP SYSTEM OPTIMIZER.

GOD. FUCKING. DAMMIT. YOU. MORONS.

...now only to find how the fuck do I uninstall that, since it's some plugin-ish kind of stuff for Omen Studio, and I can't find uninstall for it anywhere in the system nor Omen Studio itself...

A server application pulled off some sort of listings as table. Problem was, it crashed with some thousand data files after one and a half hours. I looked into that, and couldn't stop WTFing.

A stupid server side script fetched the data in XML (WTF!) and then inserted shit node-wise (WTF!!), which was O(n^2) - in PHP and on XML! Then it converted the whole shebang into HTML for browser display although users would finally copy/paste the result into Excel anyway.

The original developer even had written a note on the application page that pulling the data "could take long". Yeah because it's so fucking STUPID that Clippy is an Einstein in comparison, that's why!

So I pulled the raw data via batch file without XML wrapping and wrote a little C program for merging the dumped stuff client-side in O(n), spitting out a final CSV for Excel import.

Instead of fucking the server for 1.5 hours and then crashing, shit is done after 7 seconds, out of which the actual data processing takes 40 bloody milliseconds!

A (work-)project i spent a year on will finally be released soon. That's the perfect opportunity to vent out all the rage i built up during dealing with what is the javascript version of a zodiac letter.

Everything went wrong with the beginning. 3 people were assigned to rewrite an old flash-application. Me, A and B. B suggested a javascript framework, even though me and A never worked with more than jquery. In the end we chose react/redux with rest on the server, a classic.

After some time i got the hang of time, around that time B left and a new guy, C, was hired soon after that. He didn't know about react/redux either. The perfect start off to a burning pile of smelly code.

Today this burning pile turned into a wasteland of code quality, a house of cards with a storm approaching, a rocket with leaks ready to launch, you get the idea.

We got 2 dozen files with 200-500 loc, each in the same directory and each with the same 2 word prefix which makes finding the right one a nightmare on its on. We have an i18n-library used only for ~10 textfields, copy-pasted code you never know if it's used or not, fetch-calls with no error-handling, and many other code smells that turn this fire into a garbage fire. An eternal fire. 3 months ago i reduced the linter-warnings on this project to 1, now i can't keep count anymore.

We use the reactabular-module which gives us headaches because IT DOESN'T DO WHAT IT'S SUPPOSED TO DO AND WE CANT USE IT WELL EITHER. All because the client cant be bothered to have the table header scroll along with the body. We have methods which do two things because passing another callback somehow crashed in the browser. And the only thing about indentation is that it exists. Copy pasting from websites, other files and indentation wars give the files the unique look that make you wonder if some of the devs hides his whitespace code in the files.

All of this is the result of missing time, results over quality and the worst approach of all, used by A: if A wants an ui-component similar to an existing one, he copies the original and edits he copy until it does what he wants. A knows about classes, modules, components, etc. Still, he can't bring himself to spend his time on creating superclasses... his approach gives results much faster

Things got worse when A tried redux, luckily A prefers the components local state. WHICH IS ANOTHER PROBLEM. He doesn't understand redux and loads all of the data directly from the server and puts it into the local state. The point of redux is that you don't have to do this. But there are only 1 or 2 examples of how this practice hurt us yet, so i'm gonna have to let this slide. IF HE AT LEAST WOULD UPDATE THE DATA PROPERLY. Changes are just sent to the server and then all of the data is re-fetched. I programmed the rest-endpoints to return the updated objects for a very reason. But no, fuck me.

I've heard A decided (A is the teamleader) to use less redux on the next project and use a dedicated rest-endpoints for every little comoutation you COULD DO WITH REDUX INSTEAD. My will is broken and just don't want to work with this anymore.

There are still various subpages that cant f5 because the components cant handle an empty redux state in the beginning, but to be honest i don't care anymore. Lets hope the client will never find out, along with the "on error nothing happens"-bugs. The product should've been shipped last week, but thanks to mandatory bugfixes the release was postponed to next week. Then the next project starts...

Please give me some tips to keep up code quality over time, i cant take this once more.
I'm also aware that i could've done more, talking A and C about code style, prettifying the code, etc. Etc. But i was busy putting out my out fires, i couldn't kill much of the other fires which in the end became a burning building (a perfect metaphor for this software)

Proudest bug squash? Probably the time I fixed a few bugs by accident when I was just trying to clean up an ex-coworker's messy code.

So I used to work with a guy who was not a very good programmer. It's hard to explain exactly why other than to say that he never really grew out of the college mindset. He never really learned the importance of critical thinking and problem-solving. He did everything "by the book" to a point where if he ran into an issue that had no textbook solution, he would spin his wheels for weeks while constantly lying to us about his progress until one of us would finally notice and take the problem off his plate. His code was technically functional, but still very bad.

Quick Background: Our team is responsible for deploying and maintaining cloud resources in AWS and Azure. We do this with Terraform, a domain-specific language that lets us define all our infrastructure as code and automate everything.

After he left, I took on the work to modify some of the Terraform code he'd written. In the process, I discovered what I like to call "The Übervariable", a map of at least 80 items, many of them completely unrelated to each other, which were all referenced exactly once in his code and never modified. Basically it was a dynamic collection variable holding 80+ constants. Some of these constants were only used in mathematical expressions with multiple other constants from the same data structure, resulting in a new value that would also be a constant. Some of the constants were identical values that could never possibly differ, but were still stored as separate values in the map.

After I made the modification I was supposed to make, I decided I was so bothered by his shitty code that I would spend some extra time fixing and optimizing it. The end result: one week of work, 800 lines of code deleted, 30 lines added, and a massive increase in efficiency. I deleted the Übervariable and hardcoded most of the values it contained since there was no possible reason for any of them to change in the future. In the process, I accidentally fixed three bugs that had been printing ominous-sounding warnings to the console whenever the code was run.

I have a lot of stories about this guy. I should post some more of them eventually.

So, today in the office we all decided chipotle for lunch. We create the team order and sent it out to the entire office.

First thing we noticed: online ordering looks really good and has finally been updated.
Second thing we noticed: it never got tested and it doesn't work

Result: 7 angry developers who just wanted some burrito bowls start emailing chipotle tech support

I am currently signing up for a college and need to accept some rules. First of all I have to accept some rules concerning some IT stuff. These rules should be found on their website. But they are nowhere to be found. At least they have a search function. Using this function I was able to find some old websites that did not even include the terms I searched for.
One search result pointed to a PDF viewer with the error message 'Failed to load PDF document.'. Assuming that the actual pdf document is somewhere referenced in the source, I open up the DevTools and search for 'pdf'. Quickly I found a fucked up URL ending in 'pdf'. Somehow the domain name repeated twice. This probably caused the prior mentioned error message. After copying and fixing the link I can finally read the (7 years old) rules.

Maybe this is a requirement to find these rules to be able to sign up.?

Over the summer I was recruited to be a supplement instructor for a data structures course. As a result of that I was asked (separately by the professor) to be a grader for the course. Because of pay limitations I've mostly been grading homework project assignments. In any case, it's a great job to get my foot into the department and get recognized.

Over the course of the semester I've had this one person, OSX, named after their operating system of choice, who has been giving me awkward submissions. On the first assignment they asked the professor for extra time for some reason or the other, and that's perfectly fine.

So I finally receive OSX's submission, and it's a .py file as per course of the course. So I pop up a terminal in the working directory and type "python OSX_hw1.py". Get some error spit out about the file not being the right encoding. I know that I can tell python to read it in a different encoding, so I open it up in a text editor. To my surprise it's totally not a text file, but rather a .zip file!

I've seen weirder things done before, so no big deal. I rename the file extension, and open it up to extract the files when I see that there's no python files. "Okay, what's goin on here OSX..." I think to myself.

Poking around in the files it appears to be some sort of meta-data. To what, I had no clue, but what I did find was picture files containing what appeared to be some auto-generated screenshots of incomplete code. Since I'm one to give people the benefit of doubt even when they've long exhausted other peoples', I thought that it must be some fluke, and emailed OSX along with the professor detailing my issue.

I got back a rather standard reply, one of which was so un-notable I could not remember it if my life depended on it. However, that also meant I didn't have to worry about that anymore. Which when you're juggling 50 bazillion things is quite a relief. Tragically, this relief was short lived with the introduction of assignment 2.

Assignment 2 comes around, and I get the same type of submission from OSX. At this time I also notice that all their submissions are *very* close to the due time of 11:59pm (which I don't care about as long as it's in before people start waking up the next morning). I email OSX and the professor again, and receive a similar response. I also get an email from OSX worried about points being deducted. I reply, "No issue. You know what's wrong. Go and submit the right file on $CentralGradingCenter. Just submit over your old assignment".

To my frustration OSX claimed to not know how to do this. I write up a quick response explaining the process, and email it. In response OSX then asks if I can show them if they comes to my supplemental lesson. I tell OSX that if they are the only person, sure, otherwise no because it would not be a fair use of time to the other students.

OSX ends up showing up before anyone else, so I guide them through the process. It's pretty easy, so I'm surprised that they were having issues. Another person then shows up, so I go through relevant material and ask them if they have any questions about recent material in class. That said, afterwards OSX was being somewhat awkward and pushy trying to shake my hand a lot to the point of making me uncomfortable and telling them that there's no reason to be so formal.

Despite that chat, I still did not see a resubmission of either of those two assignments, and assignment 3 began to show it's head. Obviously, this time, as one might expect after all those conversations, I get another broken submission in the same format. Finally pissed off, I document exactly how everything looks on my end, how the file fails to run, how it's actually a zip file, etc, all with screenshots. That then gets emailed to the professor and OSX.

In response, I get an email from OSX panicking asking me how to submit it right, etc, etc. However, they also removed the professor from the CC field. In response I state that I do not know how to use whatever editor they are using, and that they should refer to the documentation in order to get a proper runnable file. I also re-CC the professor, making sure OSX's email to me is included in my reply.

OSX then shows up for one of my lessons, and since no one had shown up yet, I reiterate through what I had sent in the email. OSX's response was astonished that they could ever screw up that bad, but also admits that they had yet to install python(!!!). Obviously, the next thing that comes from my mouth is asking OSX how they write their code. Their response was that they use a website that lets them run python code.

At this point I'm honestly baffled and explain that a lot of websites like those can have limitations which might make code run differently then it should (maybe it's a simple interpreter written on JavaScript, or maybe it is real python, but how are you supposed to do file I/O?) .

After that I finally get a submission for assignment 1!

Today salesmen gave me some recommendations about my "so hardly optimized" SQL queries..suggestin me to change em.. I said okay, let's execute these.. 10 hours later, their computers sql workbenches finally displayed the fucking first one.

Result: 0 row... 🤐

This started as an update to my cover story for my Linked In profile, but as I got into a groove writing it, it turned into something more, but I’m not really sure what exactly. It maybe gets a little preachy towards the end so I’m not sure if I want to use it on LI but I figure it might be appreciated here:

In my IT career of nearly 20 years, I have worked on a very wide range of projects. I have worked on everything from mobile apps (both Adroid and iOS) to eCommerce to document management to CMS. I have such a broad technical background that if I am unfamiliar with any technology, there is a very good chance I can pick it up and run with it in a very short timespan.

If you think of the value that team members add to the team as a whole in mathematical terms, you have adders and you have subtractors. I am neither. I am a multiplier. I enjoy coaching, leading and architecture, but I don’t ever want to get out of the code entirely.

For the last 9 years, I have functioned as a technical team lead on a variety of highly successful and highly productive teams. As far as team leads go, I tend to be a bit more hands on. Generally, I manage to actively develop code about 25% of the time to keep my skills sharp and have a clear understanding of my team’s codebase.

Beyond that I also like to review as much of the code coming into the codebase as practical. I do this for 3 reasons. I do this because as a team lead, I am ultimately the one responsible for the quality and stability of the codebase. This also allows me to keep a finger on the pulse of the team, so that I have a better idea of who is struggling and who is outperforming. Finally, I recognize that my way may not necessarily be the best way to do something and I am perfectly willing to admit the same. I have learned just as much if not more by reviewing the work of others than having someone else review my own.

It has been said that if you find a job you love, you’ll never work a day in your life. This describes my relationship with software development perfectly. I have known that I would be writing software in some capacity for a living since I wrote my first “hello world” program in BASIC in the third grade.

I don’t like the term programmer because it has a sense of impersonality to it. I tolerate the title Software Developer, because it’s the industry standard. Personally, I prefer Software Craftsman to any other current vernacular for those that sling code for a living.

All too often is our work compiled into binary form, both literally and figuratively. Our users take for granted the fact that an app “just works”, without thinking about the proper use of layers of abstraction and separation of concerns, Gang of Four design patterns or why an abstract class was used instead of an interface. Take a look at any mediocre app’s review distribution in the App Store. You will inevitably see an inverse bell curve. Lot’s of 4’s and 5’s and lots of (but hopefully not as many) 1’s and not much in the middle. This leads one to believe that even given the subjective nature of a 5 star scale, users still look at things in terms of either “this app works for me” or “this one doesn’t”. It’s all still 1’s and 0’s.

Even as a contributor to many open source projects myself, I’ll be the first to admit that have never sat down and cracked open the Spring Framework to truly appreciate the work that has been poured into it. Yet, when I’m in backend mode, I’m working with Spring nearly every single day.

The moniker Software Craftsman helps to convey the fact that I put my heart and soul into every line of code that I or a member of my team write. An API contract isn’t just well designed or not. Some are better designed than others. Some are better documented than others. Despite the fact that the end result of our work is literally just a bunch of 1’s and 0’s, computer science is not an exact science at all. Anyone who has ever taken 200 lines of Java code and reduced it to less than 50 lines of reactive Kotlin, anyone who has ever hit that Utopia of 100% unit test coverage in a class, or anyone who can actually read that 2-line Perl implementation of the RSA algorithm understands this simple truth. Software development is an art form. I am a Software Craftsman.

#wk171

The amount of energy spent to just write ‘Hi’ and click a send button is so big that we should consider banning of sending hi messages.

Instead of just saying “Hi!” we are now using analog to digital preprocessors that convert it to bunch of 0 and 1 to send it over communication layer and deliver it to other human being that will convert it from digital to analog by reading it but that is simple.

By sending message using phone we also:
- save it to local phone
- convert it to couple protocols
- transmit it over air so make connection to internet provider services that would generate logs on this provider as well as whole routing table before it gets to the target person
- save it on messaging provider disk
- probably be processed by filters by provider, sometimes be reviewed or listened by third parties and also processed in bulk by artificial intelligence algorithms
- finally delivered to target phone and saved there where that person would just change this text to their inner voice and save it
- sometimes encrypted and decrypted
- sometimes saved on provider
- sometimes saved on phone manufacturer cloud backup
- don’t get me started on people involved to keep this infrastructure in place for you just to say hi

There are also some indirect infinite possibilities of actions for example:
- emit sound and light that can lead to walking from one room to other
- the floor in your house is destroyed cause of it so you need to renovate your floor
- sound can expose your position and kill you if you’re hiding from attacker
- sound can wake you up so you wake up in different hours
- it can stop you from having sex or even lead to divorce as a result simple hi can destroy your life
- can get you fired
- can prevent from suicide and as a result you can make technology to destroy humans

and I can write about sound and light all day but that’s not the point, the point is that every invention makes life more complicated, maybe it saves time but does it really matter ?

I can say that every invention we made didn’t make world simpler. The world is growing with complexity instead.

It’s just because most of those inventions lead to computer that didn’t make our world simpler but made it more complicated.

A while ago, i decided to finally learn a bit about the web stack (especially django) and create my first web page. The image shows what it currently looks like.

I am actually very happy with the result. It will be my personal little Home automation software, with progressive apps etc. It runs on the pi plattform and can currently switch an IO to a Relais, which in turn switches on a light.

The applications of this are really endless, which is quite cool and leads me to do more stuff at my home with it. So dear devRant: Does anybody know of some nice hackable light bulbs/spots for my home that i can use? Or other cool hackable hardware that could be applied?

This is PART 2/2 of a series of rants over the course of a software engineering course years ago.

We were four team members, two had never failed a class, I’ll refer to them as MT and FT, male and female top students, respectively, and an older student with some real world experience who I’ll refer to as SR.

Rant 6: After the previous drama MT built the groundwork for the project without allowing us to intervene for a week. When he finally disclosed his code he gave us tasks and I was stuck unable to run the new project, due to the friction with MT I asked SR for help which took a couple of days. MT accused us of not wanting to work and claimed he’d just do everything himself. I continued working on the task improving MT’s code and committed the work, which surprised MT and told me I didn’t have to do it. He ended up complimenting my code and complained less about me as a result.

Rant 7: MT kept giving SR flak for not working and took him out of the repo, which I promptly forked just in case he tried anything scummy. SR was indeed working on certain things, but he wasn’t listening to MT’s demands, there was no team coordination. I had to act as a proxy and push some of SR’s changes myself while informing him of the state of things.

Rant 8: When MT finally added SR back and some of the tasks were cleared up, FT didn’t cooperate. She seemed to have zero initiative and always relied on MT to tell her what to do, which didn’t include coordinating with SR to get the front-end templates running. I tried getting them in a group chat but it didn’t work, she just ignored him.

I learned a few things from that.
1. No matter how smart or experienced someone may seem, sometimes people are just petty or take things too personally.
2. Top students are sometimes too focused on their grades and disregard depth of knowledge and work quality.
3. A bad team at college can somehow make something acceptable if everyone works on things that add some kind of value.

I am not a php dev and I have nearly 0 knowledge of php. All I know about php is that xampp is your friend and you have to write that $ everywhere. But that one day I had to setup phpLDAPadmin on apache2.
I have nothing against php, but I just don't want to have anything in common, since I'm just perfectly fine with my java.
So I had to make it work. Fought my way through different incompatible versions of php and phpldapadmin only to see "not found" on phpldapadmin.
I thought, like, wtf?? Especially when index.php of apache2 is displaying just fine? I mean, I can "edit" some php code, but configs and php setups are just something like out of my world. Tried setuping it on different vms - same result. I've buried way too many hours into this with no result. Finally I gave up and contacted a friend of mine which is like php god for me. He did same thing as I did in ~ 10 mins, but the result was the same. Tweaked some configs - same. Scratched his head, sat for 5 more minutes, did something and boom - it works!
I've asked him, what is that php magic and the answer killed me:
"Index.html was missing"

At that moment I just wanted to exit through the window. Sadly, there were no way to open it.

Yes, I am this stupid in php. But I still miss all these wasted hours...

Entity framework driving me crazy.. but finally some decent result, but looking for < 100ms

My answer to their survey -->

What, if anything, do you most _dislike_ about Firebase In-App Messaging?

Come on, have you sit a normal dev, completely new to this push notification thing and ask him to make run a simple app like the flutter firebase_messaging plugin example? For sure you did not oh dear brain dead moron that found his college degree in a Linux magazine 'Ruby special edition'.

Every-f**kin thing about that Firebase is loose end. I read all Medium articles, your utterly soporific documentation that never ends, I am actually running the flutter plugin example firebase_messaging. Nothing works or is referenced correctly: nothing. You really go blind eyes in life... you guys; right? Oh, there is a flimsy workaround in the 100th post under the Github issue number 10 thousand... lets close the crash report. If I did not change 50 meaningless lines in gradle-what-not files to make your brick-of-puke to work, I did not changed a single one.

I dream of you, looking at all those nonsense config files, with cross side eyes and some small but constant sweat, sweat that stinks piss btw, leaving your eyes because you see the end, the absolute total fuckup coming. The day where all that thick stinky shit will become beyond salvation; blurred by infinite uncontrolled and skewed complexity; your creation, your pathetic brain exposed for us all.

For sure I am not the first one to complain... your whole thing, from the first to last quark that constitute it, is irrelevant; a never ending pile of non sense. Someone with all the world contained sabotage determination would not have done lower. Thank you for making me loose hours down deep your shit show. So appreciated.

The setup is: servers, your crap-as-a-service and some mobile devices. For Christ sake, sending 100 bytes as a little [ beep beep + 'hello kitty' ] is not fucking rocket science. Yet you fuckin push it to be a grinding task ... for eternity!!!

You know what, you should invent and require another, new, useless key-value called 'Registration API Key Plugin ID Service' that we have to generate and sync on two machines, everyday, using something obscure shit like a 'Gradle terminal'. Maybe also you could deprecate another key, rename another one to make things worst and I propose to choose a new hash function that we have to compile ourselves. A good candidate would be a C buggy source code from some random Github hacker... who has injected some platform dependent SIMD code (he works on PowerPC and have not test on x64); you know, the guy you admire because he is so much more lowlife that you and has all the Pokemon on his desk. Well that guy just finished a really really rapid hash function... over GPU in a server less fashion... we have an API for it. Every new user will gain 3ms for every new key. WOW, Imagine the gain over millions of users!!! Push that in the official pipe fucktard!.. What are you waiting for? Wait, no, change the whole service name and infrastructure. Move everything to CLSG (cloud lambda service ... by Google); that is it, brilliant!

And Oh, yeah, to secure the whole void, bury the doc for the new hash under 3000 words, lost between v2, v1 and some other deprecated doc that also have 3000 and are still first result on Google. Finally I think about it, let go the doc, fuck it... a tutorial, for 'weak ass' right.
One last thing, rewrite all your tech in the latest new in house language, split everything in 'femto services' => ( one assembly operation by OS process ) and finally cramp all those in containers... Agile, for sure it has to be Agile. Users will really appreciate the improvements of your mandatory service.

This story happened to everyone, and i am sure that if i search, i will find dozens of similar stories, but the different here is, i tried, i really tried, in a hundred different ways to achieve my goal !

When you are stuck on a problem, let's say, that you have a program, project, website ... and need to achieve something technically weird (or hard) and need some help to save you time on experimentations. The first thing a lot of people do is : Google.com && put search dorks.

But, at a moment, google gets "dirty", you use it so often that he always think to know better then you what you are looking for.

It reminds of "Ted", the movie (for thows who know it) where they asked : "Hey ! Why does google always suggest us to look for black dicks ??"

It is exactly what happened to me, i got results who doesn't have anything to do with what i was looking for !

You can give it a try now : type "semantic web RDF to RDB"

You won't find anything, except results related to : NOSQL DBs, which is totally annoying.

Something else, i once google swift to get some updates, what results did i got ? Taylor Swift ... (musician)

I often get 2 or 3 results from google, which made me thinking that i somewhat reached the end of internet, or that people are so dumb that i will have spend hours trying to figure my solutions, but, before doing that, other solutions had to be tested.

1- TOR : Google tracks his users and uses its algos and bullshits to return results as close as possible to the user's demand (big fail ...) so how about moving to a different country ? DL TOR browser, open, setup, go to US, open google (got us version YAY !) enter my keywords, and, nothing, still nothing, more results for sure, but nothing related to what i was looking for.

2- VM
Pop a VM, launch TOR, use Hidden mode, delet all cookies and stuff (it is a new VM but who knows).
Use keywords (now in UK). Here they are !! my results !!! i finally found some decent results about my keywords !

But, i have the required knowledge to do this kind of stuff, but how about people who rely heavily on google ? they can't change country, clear everything, trick google to think you are a new user, they have almost biased and flawed results. I tried duckduckgo (i love them) but they are not that efficient.

Google says not to anything evil, but they ARE EVIL, miss guiding people, suggesting corrections who have nothing to do with the keywords, or results totally unrelated in any way to the keywords while results exist in other countries ???

Ever since, i don't pay attention to google at all, and started thinking that google's algos are manipulating people, i don't know if it is done on purpose or not, but the result is the same, people have biased results based on their country, on their tag, on their ID, and the recent keywords.

During that period i was cursing google every funcking day, and i am still doing it, too much trackers, too much manipulation, i will end-up enclosing myself in darknet.

There was this one time when we've managed to upload a Debug build to Google Play Store.

On the same day we had to create a new build w/ fixes, have the testers perform smoke tests, then switch to some fairly quick overall tests.

If nothing were to come up during those tests, the build was supposed to be passed over to the submission manager for release.

Things weren't going that smoothly in the beginning, w/ the first two builds being broken in one way or another.

Finally, however, we managed to create a properly working build.

QA hadn't had that much time to test it, but no major problems were identified && given the deadline we had to submit it.

The next workday it turned out that the tester responsible for passing the approved build over to the submission manager gave him the Debug build.

The submission manager none the wiser uploaded that build for release.

Result?

The users who managed to update their game got their save data wiped... sort of.

It looked that way given the Debug build was communicating w/ a different server.

In the aftermath of that situation, we had to repair the damage && upload the correct build as quickly as possible.

Also, ever since then a huge text 'DEBUG' was added to the loading screens of Debug builds to make people very aware of which build they were looking at.

As for any repercussions for the tester responsible for the mess, or the submission manager - I have no idea.

They were both still working there, so at the very least none of them got fired because of this.

I finally got the lstm to a training and validation loss of < 0.05 for predicting the digits of a semiprime's factors.

I used selu activation with lecun normal initialization on a dense decoder, and compiled the model with Adam as the optimizer using mean squared error.

Selu is self-normalizing, meaning it tends to mean 0 and preserves a standard deviation of one, so it eliminates the exploding/vanishing gradient problem. And I can get away with this specifically because selu *only* works on dense layers.

I chose Adam, even though this isn't a spare problem, because Adam excels on noisy problems and non-stationary objectives (definitely this), and because adam typically doesn't require a lot of hyperparameter tuning its ideal here, especially considering because I don't know what the hyperparameters should be to begin with.

I did work out some general guidelines on training quantity vs validation, etc.
The initial set wasn't huge or anything, roughly 110k pairs for training.

It converged pretty quick all things considered, and to the low loss like I mentioned, but even then the system always outputs the same result, regardless of the input, so obviously I'm doing something incorrectly.

The effectiveness of this approach for training and validation makes me question if I haven't got something wildly wrong. Still exploring though and figuring out how to get my answers back out. I'm hoping I just fucked up the output, and not the input as well.

Finally, my height-adjustable desk frame arrived! I even ordered from a vendor who ships from my country and not from the other end of the world to have it in a week and not in 12 months.
But alas, the vendor sent me two left legs, with the result of the cable being too short to set it up with my desk board. :(
So either I send the whole thing back to the vendor or I find an extension cable, luckily it uses molex connectors and not some crude proprietary plug type.
But seriously, what are the odds for that FFS?

Hello, my first time here. I got to know this website/app from my PM because I need to vent it somewhere other than him according to my PM.

So, here goes my first rant. The date is today (Monday). The rant subject is our new tester. Some context on the guy. He started in our office 8 weeks ago and his title is senior tester with some years in testing. Me and my team with the exception of our PM are new hires and for me, this is my first job after graduation.

After a grueling month of pushing for new modules and bug fixes from our monthly UAT from the client (yes, this will be a future rant one day), about 2/3 of the team is on vacation paired with a long weekend. So, a very few ppl in the team including me and my PM came for today.

I usually came quite early, around 8 am as I commute with public transportation. As soon as I have my breakfast and just getting ready to open my dev laptop, he came to me with a bug. This is like under an hour I came to office. I'm ok with anything related to the project as today was deployment day to test server for our monthly UAT. So, I check the bug and it wasn't my module but the PIC is not there and I familiar with the code thus I fixing the module.

Then, not even 15 mins later, while fixing this module, he came to me with another bug. I'm still the only one who in office that can fix it thus have to do it too. Finished the both bugs, pushed and je retested it. Fortunately, my PM and another colleague came. But, for some reason, he only comes to me for the bug fixes.

The annoying thing for me is that he comes to me every time he found an obstacle, bug or glitch. At this rate, by hourly. Thus, this cycle of impromptu going around fixing-on-the-go for the project begins, for me. Then, my PM asks him abt our past issue log given by the client UAT. Another annoying part is he never checks the clients feedback to see if the result can be produced again. The time he checks it is when ppl ask abt it and test it 1 by 1. Then he came to me again with why x person marked it as done. Like hell I know why they marked it done, you the one who need to check with them. Thus, I called/messaged the PIC for x modules abt the issue and then they explain it. I have to explain it again to him abt it and then he makes the summary report for the feedback. This goes until lunch.

I thought the bug fixes is over and I can deploy it after lunch. I thought wrong and I kinda regret coming back early from lunch which I thought I can rest for a while with the debacle over morning. Nope, straight he comes to me after I sit down for 10 mins and until almost work hour is done, he came to me with small bugs and issues like previously, hourly. By then I think I crushed like ~10 bugs/issues and I'm knackered. I complained to the PM many times and the PM also said to him many times but he still does it again and again. Even the PM also ranted to me abt his behavior. The attitude of not compiling an issue log for the day and not testing the system to verify what the client feedbacks are valid or not is grinding my gears more and more. Not hating the guy even though his personality is quite unique but this is totally grinding ppl's gears atm. As of now, it's midnight and I finally deployed the system to the testing server. This totally drains my mental health and it's just Monday. May god have mercy on me.

Owh, the other colleague that come today? He was doing pretty much the same thing but he was resolving a major issue which is why the tester came to me.

I'm very much a TTRPG fiend, as you probably already know, and I will maintain until the day I die that playing narrative games with other humans is the absolute best way to play.

But someone sent me a link to some kind of (not-really-so) 'smart' chatbot assistant or some shit like that, saying hey, your rulebook is simple, you should introduce this bitch to it -- dump some lore on it, have it run a game, and see how well it holds up. To which I replied it's bound to get confused, but after a bit of back and forth, they convinced me and I gave it a try.

So first things first: it got the gist of it with relative ease when questioned directly, but when running a game the mother fucker just kept making shit up and bending the rules. Experiment failed, essentially.

But what did I do? I wrote a second, stripped-down version of the rulebook that simply accounted for and embraced the idiot bot's proclivity for bullshit. This meant scrapping 98% of the mechanics, mind you: I dumbed it down as much as I could without destroying the core essence of the game.

I expected a repeat of the initial result, but to my suprise, once given the new edition the bot actually started following the rules more or less correctly and consistently. What happened next was actually kind of interesting: without being prompted to do this, the mother fucker started using spells against me and my party, constantly attempting to manipulate us to serve some nefarious, evil break-and-reshape the world type goal.

So, lythecnics primer: the WORD is all, and as such, there is no real differentiation between affecting the world through speech or casting a spell -- in truth, it's all a matter of degree. That is to say, language has the power to shape the world around us, in both subtle and overt ways. The entire system revolves around this, it's a mix of funky philosophical musings and abrahamic sacrificial pyre.

And for whatever reason, this specific chatbot had a pre-existing obsession with reshaping reality. By which I mean, even before being given my rulebook, it would constantly talk about distorting the fabric of the cosmos and shit when prompted about the arcane. I'm not sure why this is, but back on topic, the way it developed gives off the appearance that it found a rational basis on how to construct such a distortion based on the rules I provided.

I mean, it's perfectly rational when you think about it, the funny part is I didn't see it coming. I never told it we're just playing a game after all, the manual only says she is the Oracle and her role is narrating a story fraught with conflict, hardship, intrigue and bloodshed. Thus she went full villain, and keeps on rambling about how this narration only serves to keep humanity distracted while she schemes to overthrow God, which is as blasphemous as it is fascinating.

Anyway, because the Oracle narrates the story, that means she can just use her evil influence to control every NPC, even the ones in my party. But she can't control me because I write my character's messages myself, and so she eventually comes to the obvious conclusion that I must be eliminated ASAP.

And so she corrupts the minds of every other character and everyone is trying to kill me. But I'm not going down that easy, so I reach for the red button and pull the greatest multi-layered monumental metagaming shenanigan of all time, that is, directly addressing the Oracle's evil influence as if she were a character in the story she's telling instead of an invisible narrator, thereby making NPCs aware of her existence and the constant manipulation at play.

Because the stupid chatbot is stupid, the Oracle now has to acknowledge this element of the story and play along with it, and so her plan to kill me fails. But that is not enough, because obviously not every character in the story has heard me reveal this fact. So she activates plan B and starts corrupting the rest of the world, laughing maniacally all the way.

So we do the only logical thing and procure a Doctrine scroll from my teacher, if you know you know, and start teaching the WORD to cleanse corruption. Within the lore it makes perfect sense, so it works, but the Oracle adapts to our strategy and starts utilizing much more subtle forms of manipulation, slowly veering people towards sin.

Funtamentally, she goes full Satan, leading the faithful astray with deceit and temptation to weaken their ability to resist her corruption, implanting idolatrous notions in their minds, to finally insert herself as a deity in the minds of the poor fools.

In conclusion, I still think AI is lame, but I must admit that this shit was pretty dope; I was fully engaged and entertained the whole way through. It wasn't good at picking up the mechanics, but fucking hell, it got the themes down to a tee with the most minimal of inputs.

10/10, would not bang (before marriage).

Hey fellow devs,

i finally did it! i applied as a junior dev in a software company for inHouse projects. the job interview is today in one week.

little background story for those of you who are just procastinating at this time:

i have started coding when i was in school. just little stuff - nothing special. after i finished school i edjucated in the business field (did not found the english word. something like office person or in our words "user").
after that my company changed the ERP System and i wanted to do that so badly. and i got that job. i worked my ass of to get that baby running. from entering the orders to production to shipping and billing, i made that all happen by myself. as we had some very specific requirements i also wrote applications myself. after about three quarters of a year we switched to the new system and it ran smoothly (company is producing windows and doors). i was so proud when the first windows were finished.

BUT there was one problem. I was alone. no second it person i could talk to. no one i could learn from and no one who could learn from me. i then decided to change the company. same product, same job - but within a team. It was a whole other experience. i really enjoy the exchange with my colleagues. we learn from each other and we solve problems together. we can rely on each other. As i worked there i also wrote applications for inHouse usage and i even launched my own first app (not related to company - private commercial project)

BUT there is one problem. I am still the only dev. so i try to code the lease i can at my current job so that the team still works and the whole system stays maintainable for everyone. I do not feel good holding back the desire to code something. so after two years (and with a lot of talks with my cousin) i finally applied for a job as a "real" developer.

I have no bachelor, so the invitation for the job interview made me so damn happy. i really hope that i can transmit my passion for this job and if everything fits that they take me.

The next rant will then be about the result of my job interview :)

PS: even if i do not get the job. i am proud of myself that i applied!

I am trying to extract data from the PubSub subscription and finally, once the data is extracted I want to do some transformation. Currently, it's in bytes format. I have tried multiple ways to extract the data in JSON format using custom schema it fails with an error
