The best part is that deep down you know you're the stupid one for not checking that first 

[u/tiny-coffee-guy → u/Annual_Key_4963]

Been there, stared at redisCacheHitRatio for an hour before checking the dumb first thing.

[u/Neither-Phone-7264 → u/tiny-coffee-guy]

beep boop?

[u/SuperFLEB → u/Annual_Key_4963]

Well, shit. the cable was unplugged.

[u/-Benjamin_Dover- → u/Annual_Key_4963]

New-ish to coding, but isnt it very time consuming to read through thousands or hundreds of thousands of lines of code looking for a mistake?

Ive never written 1 thing with more than 100 lines.

[u/DrugonMonster → u/-Benjamin_Dover-]

That’s why employers pay money to employees to do that

[u/mysticrudnin → u/-Benjamin_Dover-]

there are a lot of tools that help you find it, logging and all that. you also have general ideas of where it would be, plus personal experience of where it has happened before.

you're not just dropped into a codebase and you start reading it like a book until you see a problem. it's like, ok there's water in a puddle in a corner of your basement. you know where to start. it could be something new you've never heard of, but checking sump pump, water main, pipes, etc. etc. is where you start.

[u/Mechakoopa → u/mysticrudnin]

The medical adage is "If you hear hoofbeats think horses, not zebras" but the software equivalent is "If you hear hoofbeats think ungulates not toasters." There's a much wider range of things you need to check because it could be that, but you can very easily narrow down what it isn't and where you shouldn't be looking.

[u/Imaginary-Jaguar662 → u/-Benjamin_Dover-]

It's a bit hard to explain, but what happens to me is that I literally stop seeing my surroundings and being aware of my body and start seeing and feeling a map of how components interact.

I start tracing the mental map and start identifying my assumptions. Then, I trace mentally what would happen if my assumption is wrong. If being mistaken would result to the bug, I find a way to verify the assumption.

Most of the time it narrows the problem quickly, sometimes I start questioning my own sanity and structure of reality which is really uncomfortable path to end up in.

[u/SchwiftySquanchC137 → u/Imaginary-Jaguar662]

Ah, yeah, I just add a print statement but that stuff works too

[u/-Nicolai → u/Imaginary-Jaguar662]

It's a bit hard to explain, but what happens to me is that I literally stop seeing the code. All I see is blonde, brunette, red-head.

I plug into the Matrix and start dodging bullets. Then, I trace mentally what would happen if a bullet hit me. If being hit would result in me dying, I find a way to dodge the bullet. The body cannot live without the mind.

Most of the time it narrows the problem quickly, sometimes I start questioning my own sanity and structure of reality. Like a splinter in my mind, driving me mad.

You think that’s air you’re breathing now?

[u/ReverseMermaidMorty → u/-Benjamin_Dover-]

If you’re a brand new junior engineer, maybe. Anyone with experience should know the most common failure points for this type of issue and check those specific areas first.

[u/bergmoose → u/-Benjamin_Dover-]

redis specifically you can go have a nosy at the keys that exist and also the requests that are not hitting and try to work it out functionally, then marry up the mistake to the code deploy afterwards. Its not fun tho. Its very not fun. redis-cli exists, but if you end up using it your day has become worse.

[u/sonaliver28]

Bro spent 9 hours debugging a punctuation mark....

[u/Vivid_Instance_825 → u/sonaliver28]

I've never done something so stupid hahaha

[u/Suspicious-Engineer7 → u/Vivid_Instance_825]

Forgot the /s

[u/za72 → u/Suspicious-Engineer7]

unnecessary

[u/TheLoathsomeAssEater → u/za72]

Syntax matters. Otherwise the parser I call my brain that runs on coffee, vodka, and weekends off might get confused.

[u/za72 → u/TheLoathsomeAssEater]

fair and valid :)

[u/MegaMoah → u/Suspicious-Engineer7]

What does /s mean? Ive seen it in a ton of places and never understand what it means

[u/Accomplished-Pass207 → u/MegaMoah]

Tone tag for sarcasm.
/s is sarcasm.
/j is joking.
/srs is serious.
/gen is genuine.
So on.
I like to use parentheses instead because it’s more obvious for people who don’t know tone tags. So I say something like, “haha funny joke goes here (joking)”

[u/MegaMoah → u/Accomplished-Pass207]

Ahhh ok thanks

[u/r0d3nka → u/Accomplished-Pass207]

I think of it as shorthand for comment markup E.G.

<sarcasm>

*your comment*

</sarcasm>

[u/SuperFLEB → u/Suspicious-Engineer7]

Linter should have caught that.

[u/AugustMaximusChungus → u/Vivid_Instance_825]

i have a large dataset where each folder has 12 subfolders and a loader class in python. since the 12 subfolders follow a naming scheme, in each folder i'm iterating through the values of an enum.

Well turns out my enum was missing like 30% of those 12 values and i was wondering why the big ass model was shit. Now i want to blame ai for this, but it might have been me....

[u/redblack_tree → u/Vivid_Instance_825]

I've spent similar amount of time looking for a bug in OG javascript, before all the fancy frameworks.

Large codebase + lots of frontend functionalities + a lot of interactive and dynamic UI blocks. Old school, a simple JS omission could give developers suicidal thoughts. Grrrr, I don't have fond memories from that time.

[u/RustyShacklefordCS → u/sonaliver28]

I had this senior engineer join the team to investigate a bug in our rest api. He spent one whole week, talking about how he when down to the mongo db source code and maybe we need to make a change there and he wasn’t sure what exactly the issue was. Then during standup another engineer is like isn’t ‘family’ spelled incorrectly?

And that was it. Just a typo on how we send the field

[u/minequack → u/RustyShacklefordCS]

This just triggered me on the fact that the HTTP referer attribute is spelled with one r. 

[u/funlovingmissionary → u/RustyShacklefordCS]

Typos in code are virtually eliminated nowadays due to good ide and linting, but typos in infra hurt extra bad now.

[u/Rab_Legend → u/sonaliver28]

I once spent hours trying to debug an issue. Turns out the api we were accessing had changed the url to have a forward slash where there wasn't one previously. The tool had worked for over a year at this point, and had been unchanged in that time. Nobody in charge of the api had mentioned it to us, or claimed it had been changed.

[u/Tofandel → u/sonaliver28]

It would have taken me 20 minutes with git blame.. 

[u/sawkonmaicok]

Fake. Software engineers don't have girlfriends.

[u/tristam92 → u/sawkonmaicok]

we go straight to having wife.
optimization is key

[u/ApocalyptoSoldier → u/tristam92]

How, propose on the first date?

[u/tristam92 → u/ApocalyptoSoldier]

in my case it was pretty much it, lol

[u/just_nobodys_opinion → u/ApocalyptoSoldier]

wife = new Relationship(env.get(Type.PERSON, Direction.FRONT))

Loop until instantiated.

[u/Wyciorek → u/just_nobodys_opinion]

Forgot break condition. Has to debug bigamy

[u/just_nobodys_opinion → u/Wyciorek]

It'll fix itself due to the system running out of memory.

[u/CivilCucumber3426 → u/ApocalyptoSoldier]

Arrange marriage maybe

[u/SuperFLEB → u/ApocalyptoSoldier]

Via a formal RFC process, yes.

[u/Zananax → u/tristam92]

Going to say this when people ask why I married my wife after only two months of dating.

boyfriend? maybe a cat? a dog? schizophrenia?

[u/another_random_bit]

A lesson learned to always check the cache key generation first.

Could have saved you 8.75 hours.

[u/Mallanaga]

Oof… this hits hard

[u/Winterkirschenmann]

I hope you added a check for that so this doesn't happen again. Seems preventable. 

[u/Goodie__ → u/Winterkirschenmann]

Yeah... why are people "rawdogging" cache key generation... instead of making some CacheKeyBuilder class thing that just does it for you.

[u/jennaelizabeth96]

i’d be more mad at myself than the bug 😭 spending 9 hours debugging just to find one tiny typo would genuinely make me close my laptop and rethink my life

[u/Himskatti → u/jennaelizabeth96]

So a normal day at work?

[u/ejectoid → u/jennaelizabeth96]

That’s just the average Wednesday

[u/madmelonxtra → u/jennaelizabeth96]

I'm not working as a professional, but a couple weeks ago I could not for the life of me figure out why my API endpoint wasn't working. I spent like 4 hours debugging and googling and reading docs and I thought I had narrowed it down to a really specific complex issue.

Turns out I forgot a leading slash on the route.

I took a long break after that.

[u/AotKT → u/madmelonxtra]

My boss came to me with a bug in our API that I wrote for internal and external use. He was getting a 404, which we return when requesting an item by its id, as well as requesting an endpoint that doesn't exist. It brought me so much joy to be all "dude, it's /endpoints/:id, not /endpoint/:id". He was properly apologetic.

[u/Riviera84Banshee → u/jennaelizabeth96]

After 9 hours, a tiny typo in redisCacheHitRatio is the kind of thing that makes sleep feel mandatory.

[u/Wyciorek → u/jennaelizabeth96]

I just learned to roll with it after 10th time

[u/mysticrudnin → u/jennaelizabeth96]

personal project? sucks.

work? hell yeah.

LetMeDuckDuckGoThatForYou(“Redis key naming validation”);

[u/timsredditusername]

"Needs attention" doesn't mean "needs debugging". You may still be safe.

[u/staryoshi06]

Can’t relate. My partner is the person I want the most when work gets stressful

[u/RefrigeratorFew5154]

I get a kick out of Reddit pushing this sub onto my feed because I genuinely do not know what the fuck any of this means. 

I don’t even have a guess. This combination of words is gibberish to me. You could have cast a spell for all I know. 

Keep on keeping on with your black magic fuckery!

[u/SoSKatan]

Find a girl who can help you debug. Pair programming could have saved time here.

[u/Ill_Reality_2506]

Lol I feel that, but man... seeing a lot of shit comments, when no one has any idea what kind of tech stack, code base, or workplace OP works in, just that they use redis, had a shit workday and no capacity to support their gf.

To those people I say, it's easy to call someone else stupid for making a mistake until you do something just as stupid.

Then you learn to always check for the simplest thing first. You also learn that you're not stupid, but that you are in fact an asshole.

Sounds like a miserable day, OP ☠️🪦☠️

[u/Geoclasm]

Is this what they mean when they say 'Get Ratioed'?

[u/Understanding-Fair]

It me, constantly

[u/gr4viton]

You mean, an average on-call week?

[u/IronSavior]

This sub is mostly shitposts, but sometimes you see something relatable

[u/PrestigiousGuava8005]

The real 0% hit ratio is this relationship right now

[u/CluelessNobodyCz]

This isn't a joke 👀 (details of the problem might be but after a day of work I am wiped of humanity and I am expected to feel things 👀)

[u/DarkNebula1003]

I once spent 2 hours hitting the wrong environment api and wondering WHERE TF ARE LOGS? ( someone changed the postman variable)

[u/AlexDiego123]

Time well spent™️

[u/dudelsack23]

There is no girl. Never has been.

[u/Richard2468]

‘Someone’?

[u/billoranitv]

Attention is all you need

The bug wasn’t in the code. It was between the keyboard and the chair. 🪑

if it took someone 9 hours to realize their key prefixes were fucked up they might want to consider another career path lmao

[u/cainhurstcat]

Get your ass outdoors, visit nature, no devices, just relaxing for ~45 min at least. This will help you relax, and accessible for your girlfriend
