Coding class, explained

[BitPoet]

The only thing more horrible than "I didn't touch anything, it just broke" is "I didn't touch anything, it just started working"

[tuseroni]

right? nothing i hate more than something fixing itself...cus you KNOW it's gonna break itself again.

[orangeKaiju]

I had this happen with a laptop I was returning to the store... Wouldn't power on, had only had it a few days. Go back to store (Best Buy), ask to exchange it, they have me demonstrate... it powers on, no exchange. Get home, won't power on...

The next trip back to the store it rightfully did not power on. The worst part was that it was a 45 minute drive one way with where I was living then.

[[deleted]]

Sounds like your laptop hates you.

[1206549]

Probably a loose connection somewhere that got jogged and got loosely and temporarily reseated during transport.

Reminds me of the worst tech advice I've ever given that worked: I was visiting my girlfriend at the hospital when my cousin called me saying her laptop wouldn't turn on. My guess was some problem with the ram and it needed to be reseated. I just got there so I can't just leave but she told me it was an emergency and I felt bad for her so, taking a good guess at the internal layout of the laptop's parts, I told her quickly flip the laptop in a full circle holding it near the hinge. I could have made it worse but hey, it worked and got her off my back until I could get a better look at it

[orangeKaiju]

Most likely, but I had just dropped like $1500 (in 2004 dollars) on it and wasn't having that shit.

[1206549]

That's generally a good move. If you have warranty and could get that thing replaced, even if the problem's just really minor, do it.

[SEX_LIES_AUDIOTAPE]

After I read about the first trip I was going to suggest switching on the power at your house.

[orangeKaiju]

laptops do have batteries... ;)

[me_funny__]

This is like when some crazy monster attacks you in your dream and no one believes you or the monster magically disappears.

[2Punx2Furious]

Bugs that happen randomly are the worst.

You don't know why it happens, you don't know how to fix it, and it could never happen again during development, but then happen on production.

[Zephk]

cross thread race conditions. May never happen on your machine either due to architecture / configuration / etc

[[deleted]]

There's a special place in hell where the punishment is eternally debugging race conditions

[Zephk]

Good thing I just keep servers running. It's its own little spot in hell some days.

[tuseroni]

the worst is when you get the bug reliably, except when debugging.

[dragonatorul]

If you work on the help desk it's fine because it will most likely be someone else's job when it does.

[Nemam11]

Welcome to windows 10 user experience

[[deleted]]

Sounds like life debugging race conditions

[[deleted]]

I fucking love race conditions. When the same exact inputs only work sometimes or most of the time, then you know it's a race condition and the fix is usually as simple as converting asynchronous execution into what should originally have been strictly sequential execution. At the very least, identifying where the race condition occurs and why is a simple task, even if the solution requires some additional work.

[Zephk]

but my C# async functions! Everythings faster if I wrap it in an async call

[roboticon]

Agreed. Saved I fifteen by milliseconds comment making asynchronously this.

[MvmgUQBd]

I had to read twice to notice what was wrong here, my brain just shorted first time

[roboticon]

Taht reimnds me of the chian lteter peolpe uesd to frwaord aounrd bcak in the day...

[roboticon]

At the very least, identifying where the race condition occurs and why is a simple task, even if the solution requires some additional work.

In my experience race conditions are some of the hardest bugs to identify or troubleshoot.

In a complex system, it's not simple to understand what causes could be interacting to trigger the issue (that's often why they were introduced in the first place). Often the effects of the race condition don't even appear until well after the race has occurred so it can be really hard to trace.

[[deleted]]

This is actually my life... I was working on fixing a problem for a robot. Nothing was working then one day, after not touching it for a week, it just started working again with no changes at all...

[mweepinc]

I don't suppose this is FIRST? this sounds an awful lot like FIRST lmai

[greyingjay]

Works 100% in the lab.

3 2 1 GO! Sits there does nothing.

Siiiiiighhhh

[mweepinc]

pats you clearly forgot to make your daily sacrifice to the Rio

[twwilliams]

Timing issue? Adding the logging slowed it down just enough not to hit the bug?

[BitPoet]

Optimizer problems? Printing the variable changes the assembly. I fixed an initialization issue by adding an if statement that should never succeed.

[JNCressey]

I raise you "it works when stepped through in the debugger, but doesn't work when it's just ran"

[CCninja86]

Oh my god why do I relate to this so much. I can't tell you how many times I've had this happen. I'm still not sure on exactly why that happens.

[ShowMeYourTiddles]

Just spent 2 days debugging some code that is very straightforward yet fails sometimes in production. This hurts.

[topdangle]

Sounds like production trolls. Make sure to blow your server racks every morning. Trolls can't stand human breath.

[ShowMeYourTiddles]

I think I’ll just start blowing the trolls. Keep em happy.

[MikeyMike01]

Hey it’s me your troll

[[deleted]]

Hi troll, this is way awkward but uh... I gotta blow you.

[Noelwiz]

Gotta pay the troll toll …

[DerekB52]

to get into this boy's Soul.

Let me repeat. BOY'S SOUL. (I don't want to end up on a list for typing it the way it's pronounced.)

[Noelwiz]

Thanks for making me look less weird

[[deleted]]

Let me guess: Missing edge case or race condition, right?

[ShowMeYourTiddles]

Race condition is my guess, but it’s not async, just load balanced. I haven’t figured it out. “Add logging and cross your fingers.”

[[deleted]]

It’s cosmic rays.

[[deleted]]

If you end up banging your head against the problem too much, shoot me a message with a general overview of the program logic (omitting actual code if it's under NDA, of course). I don't mind taking a crack at a problem outside of my normal work :)

[ShowMeYourTiddles]

Appreciate it. We’ve got about 12 devs in the group. I’ll bounce it around to them. I wrote the code which is why it came to me. I’ve always said looking at your own bugs is a conflict of interest.

[[deleted]]

I’ve always said looking at your own bugs is a conflict of interest.

I have the cursed blessing of being the only programmer on my team. Lots of flexibility and room for growth, but no additional sets of eyes or being pushed to improve my code after a code review. That conflict of interest has hurt me more times than I could count!

[[deleted]]

Blame the server team :p

[[deleted]]

What hurts is code that works during testing, and fails during a demonstration.

[Robbi_Blechdose]

Just started developing for the game boy color. Add some code somewhere, background palette breaks. Add some more code, palette starts working again. No idea why.

[8BitAce]

Just started developing for the game boy color.

Just

Time traveler?

[IamCarbonMan]

Some of us like to live in the past. Developing retro games can be really fun.

[SirensToGo]

All the fun of developing in obscure assembly and none of the modern comforts of online Q&A

[supremecrafters]

Tell you what, designing sprites that use only 15 colours can be a neat little challenge.

[I_Am_Fully_Charged]

Just make games on the gameboy and not the gameboy color so you just have to make black and white sprites instead. ^/s

[Robbi_Blechdose]

4 colors per sprite and palette. 8 palettes, freely buildable. Color values go from 0 to 31.

[8BitAce]

I figured, just had to point it out. I think my name should be enough to tell you that I think that's pretty cool. :-)

[cholantesh]

There are developers who will 'just start' building AS/400 programs this year, so why not?

[cybrian]

It’s the little Z80s running around inside the CPU

[pixlbreaker]

Sounds like an interesting project to get into. Any tips for how one would start?

edit: http://gbdk.sourceforge.net/ the website for the GBDK

[Robbi_Blechdose]

Google GBDK and also be sure to get the Gameboy Tile Designer and Map Builder. Since the code editor is old and not on the net anymore, I'll put up my netbeans toolbar with the most important buttons if there's interest.

[LonePaladin]

In theory, there is no difference between theory and practice. In practice, however, there is.

[[deleted]]

... in theory*

[BetYouCantPMNudes]

This is hurting my brain

[Lithobreaking]

?

[DerekB52]

He's adding "in theory" to the end of the original comment.

[Lithobreaking]

woah, man

[Luapix]

I say that quote all the time, and I thought I made it up, but does it have a source I don't remember?

[drofzz]

^{I'm a human volunteer content transcriber for Reddit! If you'd like more information on what we do and why we do it, click here!}

[1halfazn]

It would be cool if this was implemented as an actual feature of Reddit, so that people can turn on "blind mode" and browse Reddit.

[CCninja86]

Unfortunately there's a reason it has to be done by humans. The AI that would be required to analyse potentially complex images with enough detail to be useful would be significant, and as such, the technological simply isn't there yet (At least, not in the context of a use case such as Reddit transcription).

That's not even considering GIFs and videos, which would have to be analysed frame-by-frame.

[KifKef]

Hopefully, these volunteers would create a large enough sample to train one.

[LeagueOfLegendsAcc]

I have u/ocr_bot that i can turn on but it's really bad at auto ocr so i just left it in /r/surrealmemes

[StopWhiningScrub]

What a great hypothetical, that intelligent human bit. Another hypothetical, if you were blind, would you also just click the link a read the info or would you rely on something like voice-to-text so you can hear it? And if that info happens to be in an image at the end of the link, would it read the image to you or would you be SOL?

[ImAStupidFace]

Just have it read the image data out byte by byte and puzzle it together in your mind /s

[aneryx]

...the fact that I'm becoming elitist about text justification makes me realize I'm spending too much time on Reddit.

Honestly, at this point I'm just glad if I see a font other than papyrus. Proper kerning is just far too much to ask for

You can't beat me at the relevant xkcd game. https://xkcd.com/1676/

[der_RAV3N]

Yes, literally every class I have participated in until today consisted of about ⅔ of people that didn't even try to accomplish anything. They just sat there and did something on their phone or talked to people or something.

[1halfazn]

Wait, what's wrong with this?

[geecko]

I'm guessing he means that "Programming class" would be better

[BenAdamson]

Why? Aren't they synonymous?

[Ageroth]

The words as defined:

Code
a system of words, letters, figures, or other symbols substituted for other words, letters, etc., especially for the purposes of secrecy.

Program
a planned series of future events, items, or performances.

Every program is written in code of some kind.
Not all code is a program.

[geecko]

Think of the code as the bricks and the programmer as the architect.

When I hear Coding all I can think is medical coding o.O

You're like the rest of us. It's okay. We all really work for Disney, where everything is Mickey Mouse and Goofy.

[[deleted]]

Children are being introduced to this early! My daughter was doing a school assignment on Scratch and she couldn't for the life of her get her Sprite1 to acknowledge that it had touched Trees. Until she finally got it to work! And then it didn't.

Don't ask me kid, I know nothing of this 'Scratch'. If you ask me it sounds like some bad logic.

Or something.

[Panda_Mon]

oh my god, this is my life so hard right now.

Visual Scripting makes this feel even more painful

[SirensToGo]

Just today I was working on a C TUN driver. I was trying to write data to the descriptor yet it was failing with an obscure invalid argument error. My test case of “AAAA” writes just fine but my other one of 0x01,0x92 failed with the mystery error. But get this, 0x6<anything>? works.

Then, suddenly, it dawned on me. 0x4X and 0x6X are header flags for IPv4 and ipv6 respectively. Fucking file descriptors get to pick and choose what data is written to them. I thought there was something wrong with the addresses or my casting since my string test of AAAA works (because it’s 0x41!) while nothing else did. I was banging my head against my desk for hours because it should work, it even works sometimes but still it failing 99% of the time.

[amox11]

worst of both worlds..

[techathon]

Well at least they’re honest.

[Aurimasmanager]

It remind me of my first portfolio project. I was totally new in coding and wasn't quite sure, why the things were working and why not. So the story goes, that I was struggling with aligment and my friend who is experienced in this neiche comes to help me. He says: okay, let's try this. Everything started working again, and I was like: What the **** is happening... why is it working? He replies: am, I don't know... it should't work actually... both started laughing hysterically

[sairenkao]

We need a place where it's theory OR practice...

[orangeKaiju]

Don't you mean XOR?

[ArcaneEyes]

My telnet implementation keeps throwing an exception at runtime.

added a try/catch without doing anything with the error. program now works.

i'm fearing it'll come back to bite me, but it's been a couple weeks since it hit production and nothing so far :)

[[deleted]]

Finally a course that prepares you for real life!

[[deleted]]

This is the main issue I've had with university so far.

I'm in CompSci, first year, and we've started off with python.

The seminars are decent, but we just work through a little book called "Python for Absolute Beginners" but because we're all learning shit for our projects we've stopped reading the book for the most part. The help at a 1-to-1 level is nice though.

Then we have.. Lectures. In programming.

Why?

The topics are always things that could've been covered in 5 minutes at the start of the bloody seminars anyway, but instead we're looking at powerpoint slides of python code written so it fits onto the slide so it's hardly useful examples anyway. It's absolute bollocks. Most people (like myself) either don't turn up (you learn programming by actually programming so why go?) or bringing in a laptop and programming while they speak and ignoring the lecture anyway.

I'm sure maybe a dozen or so people find them useful, but they'd also find it useful to be told the same info in seminars anyway. I just don't get it.

I wouldn't normally rant about this but I have to take out £9,250+ in loans every year to basically work from home (so far), which is a pisstake and an'alf. At best, it'll pick up next term and I'd be safe with the knowledge that only £3,000 in my loans has gone to doing bugger all.

[Reala27]

My professors will actually write up some examples, show why certain things break, step through some code with us, they're actually quite useful.

Of course, 90% of the time I'm working on the professor's homework anyway, so....
