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

#1 - Most expensive lesson learned

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

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

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

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

#2 - Hardest to find

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

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

#3 - Most elegant fix

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

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

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

This may be a petty rant, but It's been grinding my gears for a few months now... I fucking hate ads, it's starting to be incredibly ridiculous. You start a video... 2 ads... you watch for 2 minutes, another 2 ads (and no, adblock isn't a solution, that only works on PC, not devices)?!!! You start an App... ads, you listen to music... ads... you go to google... ads, you click a website... ads... you look out of your window... ads... you walk down the street... ads... ads.. ads...
Seriously, what the fuck have we done?!! As a society we fucked up so badly... Look, no matter how many times you offer me an ad for a furniture, I'm not going to buy a fucking furniture on just any random day. You are completely wasting my already limited time... If you don't have any ads to show me, then don't show me ads, fuck you, you fucking piece of shit software... How is it that it used to be enough to click away one static, non-intrusive ad, but now 6-8 15-20 second ads, popups and intrusive, mid-content ads are the norm?! And then a piece of shit like MoviePass DARES, FUCKING DARES, To work on some sort of camera-enabled check that you actually LOOK at the ads?!!!! ARE YOU FUCKING SHITTING ME?! WHO THE FUCK DO YOU THINK YOU ARE YOU RETARDED PIECE OF BLACK MIRROR SHIT, FUCK OFF WITH THIS BRAINWASHING BULLSHIT, I'M ALLERGIC TO IT, FUCK ALL OF THIS.

I fucking promise that any software I'll make will be either free and open source, or paid only by alternative means, no ads, not ever. I will never fucking add to this retarded bullshit. Never fucking ever will I lower myself on a level where I need to actively waste the time and psyche of thousands or millions of people to get money. Fucking hell.... As if the world doesn't suck enough already, we treat humans as cattle, and It's pissing me off... In the past I used to just delete any app that annoyed me with ads, but what the fuck do I do about youtube since it's the de-facto content source on the internet? And worse, my friends and family watch youtube.. even if I avoid it that doesn't mean the problem is solved... There needs to be an alternative, and paying subscriptions for every single fucking service on the web isn't a solution. Even worse with the current economy... I'd rather eat real food, than buy shit like premium on ShitTube, Fuckify, all the random news website I might read and every app or game I start once every two months... Shit like ad-less premium accounts aren't giving me an alternative, just a way to shoot myself in the foot longterm...

Godbless everyone that releases open source software, apps, tools, websites and such. I hope to god decentralized alternatives to youtube need to happen and not in the web3 way, because that's also retarded...

Fuck, Fuck, Fuck, Shit, Fuck Shit, Piss, Cocksucker, Motherfucker, Retards, Fucking absolutely disgusting pieces of shit... ... alright, I got it out of my system, but It's gonna be right back the next time YouTube forces me to look at 20 seconds of something I already skipped 48 times today...

In my previous company we developed a CRM web app for the company to use internally and it was in my humble opinion really easy to make sense of, but for some freaking we kept getting calls whenever someone got an error, and our default response was always to send us an email, then we will get back to you, as it was mostly stupid things they called about, for example, a customer might have to be status terminated, before you can click button A, button A would then be disabled and employees would call asking why. Apparently, people got annoyed by our response and went to the management, to get some guidelines as to when they could call the "development apartment" for help, so the management sends out some guidelines as to when they could call, write or whatever... The following was done without consulting us in any way ANY WAY AT ALL!... Because we all know management knows fucking best, and why bother asking the people that sit with it every day, and the way it was done was by saying:

If the background color on your error is red, it means the error is fatal and you can call the developers immediately, if its orange send an email and they will answer within 48 hours LIKE WTF... Seriously???. That was basically it, and honestly we had just been using colors, without much thought to it ofc red, was an error etc. But they we're not "OMG EVERYTHING IS BREAKING" alert, so we decided to use a couple of hours refactoring the color of the flash errors, and after that, we did not have many red alerts(None, yes none what so ever) We changed all the red ones to orange, and introduced some new colors. That worked for some time around 6 months or so, but then people obviously started calling again like, why even bother... So we created a simple service desk, blocked all incoming calls to our phones that were from regular employees, heard a lot of complaints about this from the employees, management was mad, we had so many meetings with those top paid management fuckers that know everything (way better than you and me), about how to handle this. As it took way too much of our time, that people couldn't bother trying simple things, or make some sense as to why a button is disabled etc. We ended up "winning", was allowed to block calls for some time, till the employees had learned to use a freaking simple service desk, it's not fucking rocket science Okay, stop being a pain in the ass... And it actually fucking worked! Most relaxing time after people got a hang of using the service desk instead of calling life was good after that... <3

I'm still studying computer science/programming, I still have one year to do in order to graduate (Master). I am in a work study program so I'm working for a company half of the time, and I'm studying the other half. It is important to mention that I am the only web developer of the company

When I arrived in the company 9 months ago, I was given a Vue project which had been developed by a trainee a few weeks before my arrival and I was asked to correct a few things, it was mostly about css. Then, I was ask to add a few functionalities, nothing really hard to code, and we were supposed to test the solution in a staging environment, and if everything was ok, deploy it to prod.

However, the more I did what I was asked, the more functionalities I had to implement, until I reached a point where I had to modify the API, create new routes, etc. I'm not complaining about that, that's my job and I like it. But the solution was supposed to be ready when I arrived, it was also supposed to be tested and deployed.

The problem is, the person emitting these demands (let's call him guy X) is not from the IT service, it's a future user of the website in the admin side. The demands kept going and going and going because, according to him, the solution was not in a good enough state to be deployed, it missed too many (un)necessary features. It kept going for a few months.

The best is yet to come though : guy X was obviously a superior, and HIS superior started putting pressure on me through mails, saying the app was already supposed to be in production and he was implying that I wasn't working fast enough. Luckily, my IT supervisor was aware of what was going on and knew I obviously wasn't to blame.

In the end, the solution was eagerly deployed in production, didn't go through the staging environment and was opened to the users. Now, guy X receives complaints because none of what I did was tested (it was by me, but I wasn't going to test every single little thing because I didn't have time). Some users couldn't connect or use this or that feature and I am literally drowning in mails, all from guy X, asking me to correct things because users are blocked and it's time consuming for him to do some of the things the website was doing manually.

We are here now just because things have been done in a rush, I'm still working on it and trying to fix prod problems and it's pissing me off because we HAVE a staging environment that was supposed to prevent me from working against the clock.

On a final note, what's funny is that the code I'm modifying, the pre-existing one needs to be refactored because bits and pieces are repeated sometimes 5 times where it should have been externalized and imported from another file. But I don't know when and if I will ever be able to do that.

I could have given more context but it's 4am and I'm kinda tired, sorry if I'm not clear or anything. That's my first rant

Hey I just met you
And this is crazy
But here's my mail address
So spam me maybe
