I worked with a developer who insisted on using the shortest names possible. God I hated debugging his code.
I’m talking variable names like AAxynj. Everything looking like matrix math.
Ah, must've been a fortran developer. I swear they have this ability to make the shortest yet the least memorable variable names. E.g. was the variable called APFLWS or APFLWD? Impossible to remember without going back and forth to recheck the definition. Autocomplete won't help you because both variables exist.
He did write some Fortran in his past! What made you think it was Fortran influence?
72 characters per line/card.
And you can write more than six characters, but only the first six are recognized. So APFLWSAC and APFLWSAF are really the same variable.
And without namespaces, company policy reserves the first two characters for module prefix and Hungarian notation.
I vomit whenever I have to read one letter alias SQL. And then.... I dealias it.
I don’t understand why people think that it’s acceptable.
As developers, we’ve had it drummed into us from day one that variable names are important and shouldn’t be one or two letters.
Yet developers deliberately alias an easy to read table name such as “customer” into “c” because that’s the first letter of the table. I’m sure that it’s more work to do that with auto completion meaning that you don’t even need to type out “customer”.
Nah, I name all my variables after my homies.
int dave = 0;
does dave know he's a zero?
In zero-based indexing, zero is #1.
Dave was number one!
His best friends index starts at 0

I've got that shit on lockdown man.
I name all my devices "Fuck0ff" followed by a 3 letter descriptor of what it is. E.g. - my windows install is Fuck0ffDTW for Desktop Windows, my Garuda install is Fuck0ffDTG for Desktop Garuda(it's a flavour of Arch, btw)
What if you would have 2 devices of same type with same OS or just with OS that starts with same letter? Will you use numbers, if yes, how much leading zeroes if any you will use? If you don't use numbers, will you add a room name? But what if there are 2 devices with same OS in the same room?
You should really be naming all your variables by generating 64 character (minimum) random strings.
Who needs private variables when you can generate cryptographically secure variable names? Much better security.
Make it 63 (31?) to align with what C99 can distinguish.
Also: I really like unicode in identifiers. So if at all possible don't just have a random string of letters and numbers, make sure to include greek letters and all the funny emojis. (I just forgot which languages and compilers etc allow that.)
For extra fun, you can name your variables using solely Unicode invisible characters (e.g. non-breaking space) so they're impossible to visually distinguish

Older C compilers would truncate a variable name if it was too long, so VeryLongGlobalConstantInsideALibraryInSeconds might accidentally collide with VeryLongGlobalConstantInsideALibraryInMinutes.
Legend says that they used to do it after a single letter with Dennis declaring "26 variables ought to be enough for anyone".
I had this problem in my job as a drafter. I was wondering why the hell Tekla would complain about the same object name already being in use despite everything having its own name. took me way too long to realize there wad some stupidly max name length and the program did nothing to alarm the user about trying to put too long name. it just cut the overflow away.
Gotten even easier after X became a registered trademark. Now the only choice we have left is i. Or ii if you need more variables
"j" is what you're supposed to use if you need another index variable after using "i".
Single character variable names are my pet peeve. I even name iterator variables a real word instead of “i” now.. (although writing the OG low level for loops is kinda rare for me now)
Naming things “x”.. shudder. Well, the entire world is getting to see how that idea transpires hahah
I hate short variable names in general too, but am okay with them for iterators where i and j represent only indices, and when x/y/z represent coordinates (like a for loop going over x coordinates). In most cases I actually prefer this since it keeps me from having to think about whether I'm looking at an integer iterator or object/dictionary iterator loop, as long as the loop remains short. When it gets to be ridiculous in size, even i and j are annoying. Any other short names are a no go for me though. And my god, the abbreviations... Those are the worst.
X, y, and z should only be used when working with things with dimensions larger than 1. Indexing into a 2D array, x and y are great uses. I'm also totally fine with i and j for indexer/iterator when appropriate, but I hate when people try to make short variable names for no good reason. We have auto-complete just about everywhere now. Make the names descriptive. There's literally no reason not to.
An important professor constantly and frustratingly said
we can call this variable whatever we want, so we’ll call it

Made me panic and irate and focus on the wrong part of the problem. Every. Single. Time.
Then you realize your code is undebuggable because half the functions and variables have single-letter names or called foo, bar, baz, etc.
I have a somewhat related real world story. I had a client that was convinced that tons of people were going to decompile their application and sell their own version of the program, so they insisted that they needed their code obfuscated to protect company secrets and make it harder to reverse engineer. I tried explaining to them that obfuscation wasn't that big of a deterrent to someone attempting to steal code through reverse engineering and that it would likely cause some issues with debugging, but they were certain they needed it. Sure enough, they then had a real user run into an issue and were surprised to find that their custom logging system was close to useless because the application was outputting random obfuscated letters instead of function and variable names. We did have mapping files, but it took a lot of time to map each log message to make it readable enough to try to understand the user's issue.
There are only two hard things in computer science: cache invalidation and naming things.
And off by one errors
Yeah, there are 2 hard things.
0: off by one errors 1: cache invalidation 2: naming things
Why is no one giving credit to my friend n?!
name your function as malloc() and see to world burn and generate bugs at factorial rate.
for whatever in stuff:
How to write spaghetti code:
mathematician here, where is the joke?
Variable names should be "self defining" meaning you should be able to understand what its doing from the name. The name also shouldn't be too long. Combining those together makes it difficult to come up with an "elegant" name
I think they got the joke, they were just joking about how this is common in math :P
in the linux community it's really common to have applications like MPD, music player daemon, or MPC, music player client, and ncmpc, ncurses music player client, and ncmpcpp the aforementioned one with ++ tacked onto the end.
Cmus, which from what i can recall is literally "c music player"
etc....
Since a lot of the english words i know i learned from minecraft, in a farming simulator i named tilled soil"hoed"
I had multiple variables like int isHoed
Now I want to become a programmer so I can give variables people names.
Just be careful naming your function "stdout()" or things could get weird...
Or Fortran variables that collide with Fortran built-in functions.
Keep in mind that array subscript and function call are both () in Fortran.
No, that's math.
