Is it really tempting for people? They’ve given me too many headaches when I’ve had to reformat or add functionality to files.
Unless it’s a simple single use script that fit on the computer screen, I don’t feel like global variables would ever be tempting, unless it’s for constants.
Rarely have I ever actually had consequences for my sins, which tends to be why I don’t go back and fix them…
If tech debt weight is felt in any way, it tends to get fixed. If it’s not felt, it’s just incredibly easy to forget and disregard.
(This is mostly me not learning my lesson well enough from my time being on Tech Debt: The Team. I do try and figure out the correct way to do things, but at the end of the day, I get paid to do what the boss wants as cheaply as possible, not what’s right :/ money dgaf about best practices until someone gets sued for malpractice, but on that logic, maybe the tech debt piper just hasn’t returned for payment from me yet… Only time will tell)
If you’re smart you do it the quick and easy way and leave the company before it bites you in the ass. Only suckers stay with the same company for more than a few years
I.e. you did use them, but learned the hard way why you shouldn’t.
Very likely OP is a student, or entry-level programmer, and is avoiding them because they were told to, and just haven’t done enough refactoring & debugging or worked on large enough code bases to ‘get’ it yet.
Unironically: For in-house scripts and toolboxes where I want to set stuff like input directory, output directory etc. for the whole toolbox, and then just run the scripts. There are other easy solutions of course, but this makes it really quick and easy to just run the scripts when I need to.
Depends on what you’re doing. Functional programming has its own downsides, especially once you want to write interactive programs, which often depend on global states. Then you either have to rely on atoms, which defeat the purpose of the functional programming, or pass around the program state, which is janly and can be slow.
I personally go multi paradigm. Simpler stuffs are almost functional (did not opt for consting everything due to performance issues), GUI stuff is OOP, etc.
Well, if you’re writing something the user will be looking at and clicking on, you will probably want to have some sort of state management that is global.
Or if you’re writing something that seems really simple and it’s own thing at first but then SURPRISE it is part of the system and a bunch of other programmers have incorporated it into their stuff and the business analyst is inquiring if you could make it configurable and also add a bunch of functionality.
I also had to work with a system where configurations for user space were done as libraries setting global constants.
And then we changed it so everything had to be hastily redone so that suddenly every client didn’t have the same config.

Most people suck at software engineering.
Plus, there’s always the temptation to do it the shitty way and “fix it later” (which never happens).
You pay your technical debt. One way or another.
It’s way worse than any gangster.
Not if you leave the project soon enough. It’s like tech debt chicken.
Then, at your new job, you see garbage code and wonder what dumbass would put global variables everywhere
That’s how this industry works ;)
You’re gonna see that even if you were pious at your own job. So you’re only wasting time.
amen
double amen
// TODO: Fix later
In a 10 year old commit from someone who’s left the company 5 years ago.
Later is the name of the intern my company hired when I resigned :)

For me most of the people who have written our most annoying tech debt left the company long time ago.
What industry do you work in?

and thats why we are reading a book about clean code at my apprenticeship
This community makes more sense when you realize the majority of users are CS students.
Pointers hard!! LOL
Hey, don’t you group me in with people who have had a small amount of real training!
I.e. you did use them, but learned the hard way why you shouldn’t.

I don’t get it either. Why would you ever feel the need for them to begin with?
In software that’s already badly engineered. Either you do the work and refactor everything, or accept it’s probably not worth all the effort.

But those would be constants, not variables.
I typically don’t declare them as such - bring the pitchforks!
Everything’s a variable if you’re brave enough.
My
void*doesn’t care about yourconst!As with the sexual connotation here, the temptation is not rooted in long-term considerations like future maintainability
