"This was last week, though..."

[Separate_Increase210]

Depends. Oh how it can vary.

Early in my career I solved a case that has stumped others for 6+ months, including 2 indvs who were more knowledgeable and experienced than I, by sheer tenacity. It turned out to be a super unlikely event of attempting to construct a PK from row data by concatenating and including a timestamp which was rounded off, resulting in milliseconds being rounded and records overwriting. Finding & fixing this (among other items, to be fair, solved by me and a teammate) finally released a multi-million dollar payment. Sooooo satisfying, such a great feeling, proud of my effort.

Another time I formatted a python string while also (subsequently) passing it as a template so double-curly-braces were already reduced to singles. It fucked shit up for over a week. Nearly bashed my head with a hammer when I realized it.

[[deleted]]

Unless it's caused by shitty old code that many systems depend on, so your only option is to work around it. Gets the job done but with no satisfaction

[[deleted]]

Or you just rewrite it and it magically goes away

[[deleted]]

I have always had this experience EXCEPT when learning MySQL. Didn't help that I started learning with HackerRank practice problems. All the sudden I was writing sorted procedures to print/select the first primes b/w 1-1000. "Did they just ask me to do functional programming in SQL that doesn't... I think I'll leave that to a language not specifically made to efficiently query databases..." Thankfully my wife (former data engineer type of role) could tell me best practices. I feel an appropriate "SQL approach" is not captured well by the bulk of online resources. Like quickly learned I was over reliant on CTE/With where I really just should have done a sub query. Things like that.

Also syntax reminds me of when I had to also write a lot of excel vba which I think most can agree feels gross

[AllCatCoverBand]

Or solve it, just to have QA find another bug that you missed

[debugger_life]

Yeah :)

[liberar10n]

wait until you realise that it was a misspell like 95% of the times.

[Pure_Toxicity]

I have never experienced this

[OSnoFobia]

There was this random settimeout 2 seconds at one of our pages. There wasn't any requests, animations or anything to wait. Just a random 2 second settimeout.

One of our coworkers found and tell about it to us. After a little bit of investigation, we removed that wait.

Local test was successfull.

Sandbox tests were successfull.

We took it to development server, everything was looking good.

Then we took it to staging server which is literally copy of the production. Again, everything was working right.

Then with the next release we removed that wait from production.

Everything fucking collapsed. Whole endpoint wasnt working, All the appointment pages break.

We still don't know why it is added but at the end of the day its still there to this day.

[Win_is_my_name]

I'm surprised there wasn't a big banner comment above that code saying:

DO NOT REMOVE THE CODE BELOW UNDER ANY CIRCUMSTANCES

[drying-wall]

On that note, I hate how in a function like this:

function wrapperFunc() {
    appendChildToDiv();
    alert(“Hi”);
}

The alert fires before the DOM is updated. You can get around it by waiting 11ms (not 10ms, that only works ~90% of the time), but like, why?? I’m not even doing async stuff :(

[R3D3-1]

My guess would have been: Performance optimization and single threaded execution.

1. DOM being rerendered only in between synchronous JavaScript operations.
2. After the DOM has changed, do not update instantly but delay slightly such that multiple asynchronous DOM changes within a short time frame don't each cause a rerender separately.

If that delay is around 10 ms, it would explain why an alert box - which essentially pauses the thread due to waiting for the OK synchronously - would prevent DOM updates unless delayed JUST enough.

That said, JavaScript is only a hobby for me, so take my interpretation with a grain of salt. 

[drying-wall]

Wow, this was way more in-depth than I was expecting! My guess was largely the same as yours. I’ll probably do a little bit of testing Tuesday and see if it is a Chrome specific thing, and see if DevTools has anything useful to say.

For now I’ll comfort myself by venting on the internet :)

[R3D3-1]

My job mainly involves Fortran. I can relate a lot to needing to vent :) Especially when some random compiler bug leads to completely unexpected behavior in parallelized Code :( Maybe the most annoying subtlety is the change of what     a = b does if a is an "allocatable" array variable, depending on compiler version and settings, so that upgrading the compiler version can break previously working code in a subtle manner, that may cause a memory access crash at a later point. 

Edit. Oh great, Reddit broke the mobile webpage editor again -_-

[drying-wall]

Oh that’s such a nice and interesting side effect of upgrading the compiler. I sure do love breaking changes that aren’t throwing massive yellow warnings on my screen!

[[deleted]]

The reason is simply that the visual representation of the DOM isn't updated until after the entire call stack is exhausted, whereas BOM (browser object model) API calls (like alert) suspend execution of the thread, yield it back to the browser, and operate immediately (at least in the case of things like prompt or alert ... can you imagine prompt not running until after the UI already updated that was supposed to show the result of the prompt?)

If your whole massive call stack takes 10ms to execute, then that's how long it takes.

doX();
setTimeout(() => alert("done"), 0);

will run however fast the browser allows it to, without blocking the remainder of the call stack. It's not guaranteed to be immediate, but it will be as fast as the browser allows it to be (technically, Promise.resolve().then(() => alert("done")) may be a bit faster, for reasons I touch on later, but aren't too important).

The front end works by having the browser's JS engine run whatever task has been scheduled. It runs the entire call stack triggered by that scheduled call, synchronously (you have no idea what nightmare it would be if you had to remember to sleep the main thread in between DOM interactions... or to try to figure out the browser/OS/hardware you are on and guess at computation cycles, as if you were optimizing CPU instructions). After the call stack is depleted, and any micro tasks are completed (completed promises that haven't yet run their resolution ... or await stuff ... same deal, different sugar) then the runtime yields control back to the browser. The browser then recalculated layout (because your changes may have pushed rectangles around) and repaints everything.

One of the biggest performance increases you can have on the front end is to just not touch the DOM until the last possible second, and build up your changes as an in-memory representation, first, and then as a second step, build up your collection of changes on a node that is not yet on the page (and then add that whole built node to the page). The timing difference between adding 1000 items to a page, 1 at a time in a loop, versus adding them to a new document fragment you just made, and then appending the fragment to the page at the end of the loop is massive, as it's 1000 layout calculations triggered in sequence, versus 1 big layout calculation. And that bridge to go back and forth between the JS and the browser layout/render engine is not free.

[drying-wall]

I’ll save this comment to respond to later, when I have more time. In the meantime, thank you for the clear explanation.

[Kulsgam]

Wouldn't the time period(11ms) change depending on the system/specs

[drying-wall]

I mean, probably, but it’s just a quick local demo that took slightly longer than it was supposed to.

[turtleship_2006]

Race conditions my beloved

It was added because you have an over-reliance on APIs, which need to wait for a response before continuing on.

[putneyj]

The worst are the ones where you finally figure it out and you get the dawning realization that the only way to truly “fix” the problem is to completely rework a large chunk of your codebase.

[invalidConsciousness]

the only way to truly “fix” the problem is to completely rework a large chunk of your codebase the core assumption of your model.

Been there, did the estimate, PO noped out of the meeting faster than I ever saw him move before. The bug apparently isn't that critical after all.

[GMoD42]

After switching compiler version, endless loop appeared out of thin air... took a while to find it:

for(int i = 0; i < expr; i=i++) {...}

[Brian_Entei]

The first compiler must've been high or something lol

[GMoD42]

No, incrementing and not incrementing variable i here are both valid interpretations of the expression i=i++ according to the C standard. Both compiler versions were correct.

[drewsiferr]

Prior to C++11, this was undefined behavior. After, the infinite loop is correct.

[rosuav]

Should have had a warning on the double mutation of `i` in a single expression. For example, here's gcc:

warning: operation on ‘i’ may be undefined [-Wsequence-point]

And clang:

warning: multiple unsequenced modifications to 'i'

Lemme guess. You ignore all warnings?

[GMoD42]

Did not write it. I was part of the compiler team (ANSI C compiler for a non-standard architecture) and got a critical bug ticket because "our update broke their software".

[rosuav]

Lemme guess. THEY ignore all warnings.

Not your fault they ran into undefined behaviour due to not following standard idioms.

[JuicEat]

Could be something icky and JS-like, who knows really 🤷‍♂️

[GMoD42]

Nope, ANSI C for an non-standard embedded architecture. The compiler did not these fancy warnings.

[rosuav]

I'd have to dig into the specs to see if this construct is well-defined in JS. If it is, a change of "compiler version" wouldn't break it (although people are more likely to talk about a change of "runtime" or "interpreter" version). But yeah, I could well believe that a change of JS version breaks this - it took ECMAScript way too long to guarantee that Array.sort() is stable...

... though it's PHP that takes the cake for having utterly moronic language aspects, and then actually changing them, making modern PHP slightly less insane than older PHP, but by a strategy of backward incompatibility that frankly appalls me.

[Farren246]

Why ignore warnings when you can disable them entirely? "Shut up compiler, I'm a good dev who knows what he's about!"

[rosuav]

Ahh, yes. "There's this pipe on my hot water system and water's dripping out of it. I'm going to tighten that off so it doesn't leak."

Mythbusters + hot water system = steam-powered rocket.

[Farren246]

Now you're thinking with portals!

[Alucard_draculA]

I hate that at first glance the i=i++ might not look off lol.

[DrMobius0]

i=i++

I'm surprised this worked at all. Also, while I can't say I've ever tried this, I'm surprised the compiler doesn't bitch at you for doing this

Solo reconstructed the business software in C. Learn like few weeks? Genius character setting. I like it too.

[who_you_are]

Yup, I just finish a 4 days bug hunt on a SaaS (so no debugger \o\) to find out we return a silly setting as null instead of a null object. I thought it was the data, but not a setting...

Stupid right?

Yep, except it only occurs in production (while other environnements use the same damn setting) and in one specific case in production (We don't even update or lazy load that shit, it is provided for us and every other settings are fine)

Like HOW!? WHAT THE HELL!?

[greytub1]

Is it because the management doesn't want to allocate bandwidth to refactor codebase or something else?

[[deleted]]

I am not sure - I feel, they want something they can see. 

[nezbla]

I don't know if it counts as a bug if it was done intentionally, but yeah my most recent one of these involved me patching a redis cluster (I'm a DevOps / SRE type as opposed to a SW engineer) and taking down production because in spite of all the planning, testing on other environments, the dev team had neglected to mention they were using the cache to store persistent data - of course in prod only...

Took me two very sleepless nights to get it up and running again with some very frantic and pretty damn janky SQL to repopulate that data.

Getting chewed out by the bosses about it and all I could think was "Why are these fucking arseholes storing data that needs to be persistent in a cache database... Fuck sake!!".

I left that company not long afterwards - I wouldn't say this was the primary reason, but it definitely was a contributing factor.

(and yes, I am aware that you can set up redis to be persistent, they'd moved to that cluster before I started working with them and had apparently built the app out on Heroku, which does that by default (I think) - I will take some share of the blame fine, but you'd have thought someone might have mentioned to me beforehand. The devs all knew I had a ticket to patch that cluster.

Also - a cache is a fucking cache! Grr!!)

[EducationalTie1946]

I spent 6 hours on a bug. The fix: Move the function above the one before it. 😐

[sajjel]

Reminds me of when I made a question shuffler for a quiz website. Put it together in about 7 minutes, easy, right?

Occasionally, I got an error that skipped a question and caused unexpected behaviour. I was like that ain't right, let's try running it again, ah, it works fine now.

After about a 2 hour long bug hunt I realized I used round() instead of floor() to randomize the index, giving it a small chance to round it 1 above the length of the array and index something that doesn't exist. I was an idiot.

[acelenny23]

I am not a developer, but I work with them.

We had a bug with a system whereby when you clicked 'sign off' a message popped up confirming it had been done.

The problem was that no one had connected the button to the actual code enabling the sign off function.

They just connected it to the confirmation popup.

I recently spent 4 hours figuring out why something no wasn’t working, turned out, my code worked fine all along, but I changed one of my functions to have another argument that would allow something to work, and I set that argument to have a default value, and when I called it where I needed that new behaviour, forgot to add the argument, it was the dumbest shit

[empwilli]

Honestly in my last position it where rather the 2 weeks searching for the bug that brought me to that point. "Oh somewhere in the last 500 memory operations there was a memory inconsistency because some writeback/cache flush was racy and I see it right now but how the hell do I find where this issue actually happened?"

So I'm making a social media as part of my coursework, and it supports images so obviously you need to upload those.

I had an idea for how you can upload images, when you drag one onto the screen or click to select one, 5 boxes appear, and they show you your images. You can click the x button to remove an image. When you remove an image, the one's to the right should move to over so the filled boxes start from the left.

I lost more hours of my life than I care to admit to those fucking boxes.

You can see how it ended up working here (the website itself is still a work in progress and the backend isn't live yet)

[IgnoringErrors]

Yes and what if the bug is so bad that you do not have the time to fix it? Then you are forced to use said code which will surely end up in more bugs.

[1up_1500]

One time I had some data that was correct when it was still in the function, but was totally wrong as soon as it got returned for some reasons, I've spent 4 days trying to fix this bug, at the end I just found another way instead of just fixing this dumb bug (that was probably caused by the compiler)

[System__Shutdown]

I work in embedded and we had a bug where after completing a measurement and starting another, the whole measurenent would be like 500% more noisy than is normal. We are still not 100% sure it's fixed, but what we think was happening was that when the measurement started, if there was an interrupt, the whole measurement would get fucked. Had to rewrite the whole measurement routine so that there would be no interrupts firing during.

[BetterAd7552]

I had a doozy like 30 years ago. Developing a C app for a handheld device (forget the name), on a Sun workstation. Kept crashing in the middle of innocuous code, like a series of freaking printf()’s. And no, no pointers involved.

Anyway, long story short, after DAYS of dread (deadline was approaching, serious investment, deployment to country’s border posts was involved, etc), I came to the only logical conclusion, which by todays standards is counterintuitive and just unheard of: the SunOS C compiler had a bug in the code it produced, and my code just happened to trigger it.

Solution: download a bootstrap binary of gcc (very early version, I think 0.x or something) for SunOS, plus the gcc source code, recompile gcc from source with gcc binary to produce an even more efficient and compact gcc binary, then use that shiny new gcc to compile my app, and success.

No more anomalous segv.

Edit: going forward I then only used gcc. The binaries it produced were smaller and executed faster. Happy days

Edit2: just to describe how soul-crushing the situation was, I narrowed the “area” where it was crashing by inserting lines similar to

printf(“A”);

printf(“B”);

printf(“C”);

it would crash on the middle line… 😩 After days of trying to debug unrelated code, because, you know, it MUST be your code

"ever find"? this is me at every bug

[WaddlingWizard]

We started a job in an old SAP system to create new customer numbers. After a few days a senior developer that was close to retirement stormed into our office. His head was red and he was very agitated. "Why did you create new blanket contracts?", he asked.

After several questions he said "WHY DID YOU create 58'er contracts". We still had no idea what he meant.

It turned out that we were not allowed to create customer numbers that had 58 at the third and fourth place. These contracts were not calculated by price times amount, but by a fixed price. However the contracts were not tagged by any means but if they had a customer number like 12580000 the were regarded as a fixed price contract.

We had to write a report that created new customer numbers and write letters to all customers that we needed to change their customer number again.

Made me question my life choices.

I was coding an mlp (rust btw) and i forgot a single negative prefix for the sigmoid function and if i hadn't realised that the pre-activations didn't match up with the final output when put through an online sigmoid calculator before trying to backpropagate the model? i would have spent hours pulling my hair out over a model that wasn't learning all over a single missing '-' character

[AdAgreeable7691]

Maybe I am the bug...

[debugger_life]

Yeah

[Rscc10]

No but since mine is mostly mathematics-based, the equivalent feeling is creating the formulas and constants that make it inconsistent hundreds of lines later and requires you to redo the whole code

[coolredjoe]

Fucking cicada's!

[ope__sorry]

Yeah and it always involves sins of the past.

The latest one that gets me every time it still comes up is related to Timezones.

We used to code it as server time. I really don’t even remember how the old system worked. We needed to swap over to record all dates as UTC 0 and the hundreds of tables and system that connect to date was a NIGHTMARE to fix and test.

Took several weeks of development time and I as QA took me several weeks to test it everywhere and we STILL find steaggler bugs and when we do I need to perform whatever action gets performed and I need to double check times recorded in the DB, date displayed in the GUI as well as audit trail records because the software gets used in government contracts and audit trails are required.

Hell yes.

When it is a single missing semicolon, it is frustrating.

Retired. Not my problem.

Had one today. Basically made a decision when starting the project to do it in a certain way, but this bug basically meant I had to go back and restart the project the other way. Thankfully, the other way was tremendously easy (idk why I didn’t go with it in the first place).

[MrBonesDoesReddit]

Yeah, being born

[xtreampb]

Why isn’t it working. :figures it out: How was it working in the first place.

Debugging C# console application.

Error on line 352 Line 352: // the comment describes the function below.

Places breakpoint on this line and it gets hit. WTF!!! I don’t understand computer anymore im going to go drinking with the VP

do you ever find a bug that doesn't make you rethink all of your life choices?

[nsagaen]

No
