Story #1: So I took a month of parental leave. And was planning to extend it a little longer to deal with my final exams. I was planning to spend lots of quality time with my wife and newborn son. Little did I know... It turns out that out of 5 OoO weeks I was looking forward I actually had 3 at most. The rest I've spent working remotely as I was insisted to deploy a brand new and poorly tested feature to PROD 2 days before my paternity leave. So I spent 2 weeks debugging things in PROD. Remotely. Needless to say that did suck.
Story #2: After story #1 I've learnt my lesson. This summer I took 3 weeks annual leave to renovate my apartment. I asked to not to be disturbed unless there's an emergency. And an emergency it was. One of our app users had a planned hi-load batch job lasting for 2-3 months. Hundreds of thousands of items had to be created and processed. It turns out the _processing_ algo had some flaws and was acting out. I was called out and asked to assist. I knew this sort of debugging is going to take a lot of my time so this time I put my conditions on the table: I will assist but I'll extend my leave by 1.5 the time I spend working now. They took the deal. Instead of 3 weeks I had 5 weeks of vacation!
I don't care that much about my salary. I prefer to exchange it for my time off hence I didn't ask for compensations.
Bottom line: NEVER EVER underestimate or undersell your time and effort. You are a valuable asset and if the team/client needs you on your day off -- make it count. Your time off is YOUR time. Never forget it.3 -
When I started programming Batch Files I decided to go big and and make an Batch Program with a fully functional UI system. Just when I had finished the first menu I kept getting a "goto was unexpected at this time" or something like that. I did everything I could to see about debugging until I finally cleared my calender and spent the next week debugging. A week of debugging goes by and I see someone coding in color rather then black and white at my school. I walk up to him and ask. "What language is that?" To which he replies "Batch". I asked him how he got Notepad to be in color and he simply pointed to the top left of the screen and it said Notepad++.
I get home later that day and look up "Notepad++" and download the first thing I see. I install the .msi file and I see a language bar at the top of the screen. Set it to batch, and drag my .bat file into the program to see six of my dividers are red bars. I look this up and see there's another spacing option "echo.", I replace my current spacers with this and the whole thing starts working. Fml, that's a week I'm never gonna get back3 -
Spent all day on this.
Debugging hardware is fucked man...
Me proud.
Wanted to make a devrant logo like always (its my Hello world to test my CNCs now).
And.... When I finally had the machine calibrated... The pen stopped working lol.
I'll just continue tomorrow, it's finished...
Probably gonna use a few times and make a bigger one.26 -
FUCK! agshdklgdahgisdahl;k!
I just spent 45 FUCKING MINUTES debugging try to figure out WHY THE HELL a function that is supposed to return either a pointer to a valid object OR ZERO if a valid object is not found, was RETURNING FUCKING EIGHT!
Then I saw it... I typed:
nodeList[index];
instead of:
return nodeList[index];
It took me looking at a stack trace and a disassembly of the function to realize this.
Can't wait for this three-day weekend...18 -
This probably isn't the coolest bug I've ever solved, but surely the one with the biggest faceplam
So I was building a Bluetooth smart watch that pairs with your Android device for the final year bachelor's project. The submission was in a 2 days and it was all ready and it suddenly stopped working.. Spent hours trying to fix it, even tried to get a replacement Bluetooth module (was out of stock -_-).. After a day's worth of freaking out I discovered that Android phones (at least the OnePlus X) don't connect to Bluetooth modules when their battery is below 15% -_- and since I was freaking out I would let the phone charge a bit and get back to debugging and it never crossed 15% so it never worked.. One day of debugging attempts later it suddenly struck me that low battery might be an issue.. And voila! It worked after charging the phone
Shouldn't such things be clearly mentioned in documentation :/
(Btw, got full for the project, got a 10/10 GPA for the semester)1 -
I'll use this topic to segue into a related (lonely) story befitting my mood these past weeks.
This is entire story going to sound egotistical, especially this next part, but it's really not. (At least I don't think so?)
As I'm almost entirely self-taught, having another dev giving me good advice would have been nice. I've only known / worked with a few people who were better devs than I, and rarely ever received good advice from them.
One of those better devs was my first computer science teacher. Looking back, he was pretty average, but he held us to high standards and gave good advice. The two that really stuck with me were: 1) "save every time you've done something you don't want to redo," and 2) "printf is your best debugging friend; add it everywhere there's something you want to watch." Probably the best and most helpful advice I've ever received 😊
I've seen other people here posting advice like "never hardcode" or "modularity keeps your code clean" -- I had to discover these pretty simple concepts entirely on my own. School (and later college) were filled with terrible teachers and worse students, and so were almost entirely useless for learning anything new.
The only decent dev I knew had brilliant ideas (genetic algorithms, sandboxing, ...) before they were widely used, but could rarely implement them well because he was generally an idiot. (Idiot sevant, I think? Definitely the idiot part.) I couldn't stand him. Completely bypassing a ridiculously long story, I helped him on a project to build his own OS from scratch; we made very impressive progress, even to this day. Custom bootloader, hardware interfacing, memory management, (semi) sandboxed processes, gui, example programs ...; we were in highschool. I'm still surprised and impressed with what we accomplished.
But besides him, almost every other dev I met was mediocre. Even outside of school, I went so many years without having another competent dev to work with. I went through various jobs helping other dev(s) on their projects (or rewriting them), learning new languages/frameworks almost every time: php, pascal, perl, zend, js, vb, rails, node, .... I learned new concepts occasionally (which was wonderful) but overall it was just tedious and never paid well because I was too young to be taken seriously (and female, further exacerbating it). On the bright side, it didn't dwindle my love for coding, and I usually spent my evenings playing with projects of my own.
The second dev (and one one of the best I've ever met) went by Novo. His approach to a game engine reminded me of General Relativity: Everything was modular, had a rich inheritance tree, and could receive user input at any point along said tree. A user could attach their view/control to any object. (Computer control methods could be attached in this way as well.) UI would obviously change depending on how the user could interact and the number of objects; admins could view/monitor any of these. Almost every object / class of object could talk to almost everything else. It was beautiful. I learned so much from his designs. (Honestly, I don't remember the code at all, and that saddens me.) There were other things, too, but that one amazed me the most.
I havent met anyone like him ever again.
Anyway, I don't know if I can really answer this week's question. I definitely received some good advice while initially learning, but past that it's all been through discovering things on my own.
It's been lonely. ☹2 -
New dev: I need help with this issue. I've been debugging it all day.
*2 hours later*
Me: spent a while debugging it, eventually came across a stack overflow post that says you can't do that.
New dev: oh I saw that earlier, didn't think it applied.
Me: ... why ... accepted answer "It is not possible to do this, this way".
New dev: hhhmm, ok
... get the fuck out of this building immediately.3 -
TFW you spend 30 minutes debugging an app that isn't working right only to find out it's working exactly as it's supposed you, you just forgot you put that bit in there that does that thing.
One character change later and it's working perfectly. ONE CHARACTER! THIRTY BASTARD MINUTES! I just spent thirty minutes driving through every line of code and coming closer to the conclusion that Java was doing some kind of strange thing with dropping objects from memory. No, it wasn't Java that had memory problems, it's me! Just check me into the old peoples home now so I can spend my day pissing my pants and making lewd comments at the nurses because that's all I'm fucking useful for at this point!!
I need a coffee.5 -
Regarding my last rant: I AM FUCKING DUMB!
When I receive data from the master Arduino, a hardware interrupt runs and oversteps my main loop stuff!
Lesson? NEVER WRITE HARDWARE LATCHES ON THE MAIN LOOP WITH A HARDWARE INTERRUPT WHICH IS MOST OF YOUR FUCKING CODE!!13 -
This cunt android studio, asshole. Every fucking day it would show me a pop up saying, "hey, update gradle", I always ignored it until today and that mofo has fucked up my project. Spent last 3 hours debugging as to why it is not able to resolve dependencies which were working fine earlier. And every time I click on "try again" it will resolve the dependency which it wasn't able to earlier but instead find a new one to fuck with and throw an error. Had to come back to old version resume my work FFS.2

Spent all day yesterday and a pile of StackOverflow good will on debugging the fact that I was missing a hyphen and a period.
I really, really, really suck at this.
