I wish life was like in The Office, when you just stop what you're doing and you drop the Jim stare at some camera3
The 1st rule of Rust is: You tell everyone you program Rust and how it is better than basically any programming language that existed or will exist.
The 1st rule of C++ is: There are no rules because everyone was too busy debugging templates to think of any rules.
The 1st rule of Java is: You must have excessive numbers of classes and boilerplate. The more boilerplate the better.
The 1st rule of Haskell is: It is great to learn, but you will never see it again once you leave college.38
I spent an entire week debugging my JS Gameboy emulator an year ago.
(The "C" register was read-only for some reason)
Turns out I typed "с" (cyrillic) instead of "c".4
For the love of god, I spent 2,5 hours debugging why Minecraft from the windows store doesn't work...
The game just shows a red message telling you it didn't work.
I checked the logs, nothing just warnings
I re-installed the game, nothing, same error
Updated java and all parts of the store, nothing....
Obviously I had to install Something called the "xbox identity Provider"... You know... On a PC... For a distinctly PC game to work... Installed by the store... And the provider is also on the store... But it doesn't auto-install with the game
Ever since you migrated to the Microsoft Auth the login experience is awful (I ranted about that already)
How about you do the bare fucking Minimum of an User experience and Install the fucking dependencies when I re-installed something your fucking store??!!!
The fucking bare minimum that every package manager ever created fucking has as a basic requirement?! Are you kidding me?
Rename your fucking services so they make sense and please don't waste everyone's time by having both shitty logs and no dep management for your own apps... Fucks sake16
At my first big boy job at a start up with only 50 users, we noticed we had cloud cost spikes about 20x larger than we were expecting. I remember spending all night debugging it, checking the requests as they go through.
The culprit? Someone left an async on a UseEffect with a variable that was regularly updated as a parameter.
In other words: every time a request was fired, the variable would change… so the function would sense the variable changed and fire it again, and so on.
Felt like a total hero.
Finding a forum post that perfectly describes your extremely niche problem only to have the solution posted in a bunch of dead photobucket links has to be one of the worst emotional rollercoasters of all time.4
1) Read the wiki on git. I probably have enough shorthands and test methods that you won't need much other shit to debug issues.
2) when debugging, remember that if it is there, there's a good reason why I put it there.
3) commented-out code is probably useful for maintenance. I left it there for a good reason. 😛
4) chances are whatever I wrote, was the state of the art at the time I wrote it. There might be better ways to do it now tho.
5) I always work modular. First, understand the structure. (probably also documented on wiki) DO NOT fuck up the structure. If you change it, you document it.
6) If you feel I wrote shit, it's probably because management annoyed the living shit out of me. Pun intended.
7) Your confusion is normal. I don't do dumb shit.4
> See unintelligible error from stuff that used to work and now it doesn't

> Fucktard colleague says "try using the debugger, if you run the code line by line you may probably understand what's wrong"
Dear Fucktard, I've been writing code for 7 years now, you can safely assume I know how to use a debugger if need be.
The thing: when I ask "have you ever met this error" I'm asking if you actually know what's going on, BEFORE diving in a 3 hours long debugging session of code written 6 years ago by people who have left the company in the meantime.
You don't always have to say something. Sometimes it happens: you may not have anything clever to add, and a simple "I'm sorry I don't know" is perfectly fine.1
Client: ''Perfect! How did you do this do quickly? "
Me: "I used a library"
Me: "I'm still debugging. It will take some time"
Client: "well, It has already taking too long.... I can hear Mozart in the background. Maybe you need to go to a library to get some quite and get it done fast. Visit the one you used yesterday. "
Me: "library?Ahh... I meant plug in like.... Code, a library is a bunch of packed code. "4
Never write at the limit of your talents! Remember: debugging is always twice as hard as writing code. And if you write as cleverly as you can, you won't be able to debug it anymore.🧠7
I’m trying to explain the theory behind ‘Rubber Duck Debugging’ and to be honest, they don’t believe me 😂 they say I’m drunk. Help me out here, who else uses a rubber duck or something similar to help debug code?8
Me: *changes a long and complex calculation to fix old mistakes*
Program: *keeps outputting the same wrong result*
Me: *goes mad for a good hour trying to discover the problem by debugging it like a angry rat*
Also me after one hour of debugging: *discovers he never changed the output source of the function and it's still outputting the old result*3
devops - im sick of everyone mis-using this term
it seems like everyone in the industry (even famous ppl and youtubers, not just recruiters) have clung to this word and use it as a blanket statement and it pisses me off. two parts of the word, dev (you know, development) and ops (operations, keeping shit going). yet ppl use this whenever there's more than one machine being used or something. like it's in aws must be devops, it's a cluster of machines must be devops, it's a lot of ci/cd so it's clearly devops.
if youre not keeping a system alive, debugging it, fixing errors in the environment -and- creating said environment then using the operations work to influence your development, how is it devops?
you made a build server with some kind of orchestration tool. how is that deovps?
you have a ci/cd pipeline that's in aws. how is that devops?
you built a cloud cluster in aws/gcp/azure but hand it off to another team that monitors it and pokes and prods. how is that devops?9
My current job makes me want to question my life choices.
Its a complete burnout.
I do 9 to 6 never 6 though its always 7 or 730 come home exhausted, and still on almost all days need to attend to customers after hours. Customer meeting at 8.30pm are quite consistent occuring. Being a developer, debugging meetings I can understand to a certain extent, but why the f i am preparing quotes and pitching products.
Want to prep for new job boom no time left to do so other than weekends.4
Ahh, Unity’s “Wheel Joint.” Who knew it had “polarity.” I spent good several f*<king hours debugging this $h!+ just to find out I just placed them backwards on a 2-D car. Instead of the joint turning the wheels, they were trying to “turn the chassis.”
This meant the chassis received an impossible force which would rip it in half in real life. Of course, this was a unity game, so what happened instead was the physics engine flipping out which sent the car into the air!
I guess it was good for some lulz, but it took way too long to debug. I guess it’s time to take a little time off of that project.4
**Sees a different error after hours of debugging the previous one**
ME (crying inside) - What type of sorcery is this?3
Okidoky you lil fucker where you've been hiding...
*streaming tcpdump via SSH to other box, feeding tshark with input filters*
Finally finding a request with an ominous dissector warning about headers...
Not finding anything with silversearcher / ag in the project...
*getting even more pissed causr I've been looking for lil fucker since 2 days*
*generating possible splits of the header name, piping to silversearcher*
*I/O looks like clusterfuck*
Common, it are just dozen gigabytes of text, don't choke just because you have to suck on all the sucking projects this company owns... Don't drown now, lil bukkake princess.
*half an hour later*
Oh... Interesting. Bukkake princess survived and even spilled the tea.
Someone was trying to be overly "eager" to avoid magic numbers...
They concatenated a header name out of several const vars which stem from a static class with like... 300? 400? vars of which I can make no fucking sense at all.
Class literally looks like the most braindamaged thing one could imagine.
And yes... Coming back to the network error I'm debugging since 2 days as it is occuring at erratic intervals and noone knew of course why...
One of the devs changed the const value of one of the variables to have UTF 8 characters. For "cleaner meaning".
Sometimes I just want to electrocute people ...
The reason this didn't pop up all the time was because the test system triggered one call with the header - whenever said dev pushed changes...
And yeah. Test failures can be ignored.
Why bother? Just continue meddling in shit.
I'm glad for the dev that I'm in home office... :@
TLDR: Dev changed const value without thinking, ignoring test failures and I had the fun of debunking for 2 days a mysterious HAProxy failure due to HTTP header validation...
So I made an update to my React Native app. I changed UI of a couple of screen, added a few animations here and there, refactored how my graphQL resolvers work in the backend(no breaking changes), changed how data gets loaded into the database etc.
It worked in dev so I figured hey let's deploy it. Today is(was because it's now 3am but more on that later) a national holiday so no one goes to work so no one will use my app so I have an entire day to deploy.
I started at 15:00(because i woke up at 13:00 lol). I tested the update once again in dev and proceeded to deploy it to prod. I merged backend to master, built docker images, did migrations on the db, restarted docker-compose with new images. And now for the app. I run ./gradlew assembleRelease and it starts complaining that react-native-gesture-handler is not installed. Ugh, rm -rf node_modules && yarn install. It worked. But now gradlew crashes and logs don't tell me anything. Google tells me to change a bunch of gradle settings but none of them work. Fast forward 5h, it's around 20:00 and I isolated the issue to, again, react-native-gesture-handler. They updated from 2.2.4 to 2.3.0 which didn't fucking compile. 2 more hours passed (now 22:00) and I got v2.3.1 working which fixed the problem in 2.3.0 but made my app crash on startup. YOUR FUCKING LIBRARY GETS 250K WEEKLY DOWNLOADS AND YOU DONT EVEN BOTHER CHECKING IF IT COMPILES IN PROD ON ANDROID?! WHAT THE FUCK software-mansion?
After I solved that, my app didn't crash. Now it threw an error "Type errors: Network Request Failed" every time I fetch my legacy REST API(older parts use rest and newer use graphql. I'll refactor that in the next update). I'll spare you the debugging hell i went through but another 5h passed. Its 3am. My config had misspelled url to prod but good for dev... I hate myself and even more so react-native-gesture-handler.3
Fuck you safari for automatically converting UTF-8 NFD characters to UTF-8 NFC characters. Cost us like an hour debugging!
What's your worst debugging experience?
I just had it today and yesterday when I tried to connect to an aws postgres rds..... 😭😭😭7
took me years to learn js, php, c# and I ended up now learning and debugging STL... This twisted logic is soo painfull3
Quick questions for some vim lovers out there.
I've seen a lot of youtube videos of people using vim/nvim/spacevim/... as their main IDE, claiming that they are perfectly fine with this setup. However, most of this people are programming in not heavy object oriented languages, like JS, C, Rust, Go.
My question is: are there any Java developers who are using vim as IDE and are satisfied with their setup? Is is even possible to migrate from Jetbrains tools to your setup without huge productivity drop? By productivity I mean - a lot of IDE stuff like name refactor, great lombok support, debugging tools6
Me: I've spent 2 hours on this problem, this is exhausting, I need to take a break...
*10 seconds into the break*
My Brain: I think I know what the problem is
Me: Onto another 2 hour coding/debugging session!
Who needs breaks anyways1
pair programming and debugging with your senior
referring to line number so we know specifically what we are referring to
line 69 comes up repeatedly in multiple files
what are the chances4
The it manager said that the site on my private vps where we are using a small tool as reference, is a security issue and what if it may be hacked... Well, from this point of perspective all the websites shall be switched off. The tool lovered the problem resolution from 30 to 2 minutes.. I have asked for on premise server before but noone gave a shit so I hosted on my private vps. I wont give it back for free, its a sure thing. Soon they will start to get the complains that its offline because the customer is using it for debugging too. I feel like IT and dev is really moving appart. They act as bunch of pathetic jelous guys who couldn't learn programming and ended up in installing windows on machines...7
Can you give me some tips on how to debug a massive app? (Android app running on android studio which is basically intellij idea).
For example I need to fix a bug where a certain action results in unexpected behaviour.
But oh my god the codebase is so large (mainly architecture is MVVM and rxjava) that searching for the specific place is like searching for a needle in haystack.
For example I added a breakpoint in few places, but I can see only like 4 or 5 last frames in the stack that led to the current action, last frame is a lambda which doesnt help me so frankly Im unable to even track where current event started. I am loosing my mind. I cant even find where the buttonclick action started because everything is reactive and done with observables which can be anywhere.
Any tips on debugging will be appreciated7
Well i spent an hour debugging to find out i wrote throw instead of return somewhere. I have no idea how i even managed to do that.
Me: I opened a support ticket with the software vendor last week. I haven’t heard from them yet and the can be slow to respond. I’m unable to debug the issue on my end. If you can’t wait, here are some solutions to explore. [sends a few suggestions]
Stakeholder: Can I give you examples of another error that I think is related? Is that worth exploring?
Me: 😑 No. I’ve reached the limit of what I can do for debugging. I need the vendor to answer my support ticket.
Debugging is removing various bugs from program code. So, programming is about creating and adding these very bugs to the code?👾1
Why are we debugging our stories?! Heck even our products design?.... In the end we have our tasks objectives updated mid sprint.... What is this chaos?!
Omg why are social cards so hard to debug? Did no one think of such obscure techniques as local debugging? And why doesn't Twitter show me the error message? It's the same code for fuck sake! It works with one article but not with another. There MUST be some very exact problem with one of my images, but Twitter just doesn't fucking give me a proper log.1
