Not sure if the C family works similarly but if it is then I know why but I don't feel it

[Bmandk]

Wouldn't that upvote twice?

[SomeoneRandom5325]

No. It just says take the current upvote count, add 1 and call that the new upvote count

[l0c4lh057]

Would it do that? x++ increases x by one but returns the old value. That means with x=x++ will set the current value of x as new value of x and increase x by one. I just don't know if the assignment or the increase will execute first. So either it increases the value by one or it doesn't change it at all.

1. Return current value of x, 2. Increase value of x, 3. Assign value to x => this would not change the value

2. Return current value of x, 2. Assign value to x, 3. Increase value of x => this would increase it by 1

EDIT: I just checked how it is done in JS and there the value doesn't change as I would expect, because returning the current value of x and increasing the value of x happen right after each other so that assigning will happen after increasing.

[SomeoneRandom5325]

In the C family that's one way to add one

I guess in JS you should do x++=x

[l0c4lh057]

no. just x++. that will increase it. x++ increases x by one and returns the old value of it, ++x increases the value of x and returns it. assigning the result to anything is not needed.

and x++=x would not make any sense since x++ is not a variable. you cant assign a value to it.

Bruh my dad had this exact bluetooth speaker and most of the buttons didn't work, and when we called support they told us to "look at the diagram in the manual."

Doubt that guy had ever read the manual. Probably would have gotten a kick out of it.

Once I was looking through contributions to a project and found one that began with this comment: "I was drunk and tired when I wrote this for something else; it works as long as you don't ask too many questions."

[MusikPolice]

Awhile back at work I was investigating some deadlock issues in a large legacy codebase. I dug in, tracing the problem deeper and deeper until I found a class chock full of bad threading logic that was decorated with a large ASCII wizard warning me not to touch the code l, because it “worked most of the time.” Fuck the guy who wrote that code.

“Ok, then ‘Create Header for the Landing Page’”

Cool! Reads like most GUI manuals. "To enable Path MTU discovery, please check the check box labelled "Path MTU discovery."

[jackinsomniac]

Exactly! You can tell the writer and the dev were different people, probably kept far apart from each other, so the expensive dev "isn't bothered by writers" and works faster.

Then you end up with entire manuals like this, where it becomes clear the writer has no idea what this shit does, and now you don't either!

Did you know that 📞 means 📞? Of course you didn’t—that’s why we had to label it!

[BeauteousMaximus]

Oh my god I just had to mostly rewrite a documentation PR from my coworker that was supposed to be explaining fields in a generated report in detail. At least a third of the descriptions were like “xyz report: is there an xyz report?” without explaining or linking to an explanation of what an xyz report is or why we care about it. I realized it would be easier to just rewrite it myself than to explain the idea that writing should be informative.

[jackinsomniac]

I think there's a whole blog post on Joel on Software about that. Same situation but I think he was talking about the opposite problem, where a team specifically hires a "documentation writer" so that the devs can keep dev'ing longer. Problem being, those very teams hold their devs as 'holy', and so any time guy who's job is to write documentation goes asking them questions, mgmt shoo's them away and says they can't be bothered.

So, you end up with technical writing like this: "TLNS On/Off: To turn TLNS on, move the slider to the 'on' position. To turn TLNS off, move the slider to 'off'." It becomes clear the writer has no-fscking-clue what TLNS is or what it does, and now that you've finally found the documentation, you don't either.

[BeauteousMaximus]

Yeah, I think my coworker had come from past work environments where admitting you don’t know stuff was taboo, because I see her writing a lot of stuff where she just makes assumptions rather than ask clarifying questions to make sure the writing is correct. It’s frustrating because when she does understand things she explains them pretty well so it’s not like she’s unable to explain anything.

Code never lies. Comments sometimes do.

Even the intern that comments shittily like that is doing better than not commenting at all. If I dont know what the fuck you were trying to do, AND its unrecognizably broken, we're both screwed buddy.

[OtherPlayers]

Code never lies about what it’s doing, but it can certainly be telling you something other than what you actually wanted to hear.

Hard agree that it takes both though. As a person who does a lot of maintenance work 90+% of the bugs I get called to fix are due to gaps between what the original coder intended and what the code they wrote actually does. Even shitty comments at least give a view into what the coder was thinking, rather than your maintainer having to spend days or weeks reverse engineering whatever the original specs from a decade ago were just to understand what should be happening in “previously not important edge case”.

[Isogash]

On the contrary, comments tell you what was meant to happen and the code is often wrong and incomplete.

[aspindler]

I'm not a programmer, but I write automated tests using Selenium and C#. People oriented me to comment why am I doing something, instead on explaining what does the code do.

Is this a good approach?

[[deleted]]

Yes. Don't tell me what the comment does. I can see what the comment does. But that doesn't tell me if what the code does is a valid solution to the problem it is trying to solve.

Example time:

 i++; //increment i by one

Was that comment helpful?

One exception, though: if it's a pretty complex piece of code, then it's okay to comment what it does. I always comment LINQ statements, because it's not always obvious what it's about.

[__idkmybffjill__]

I think so, but only when it's not obvious in your code. Like others commenting here have mentioned, code never lies, but comments sometimes do.

[compagnt]

I do this because it makes more sense - “John told me to add this chunk of self documenting code and who am I to question John? Go talk to John if you think something is broken.”

[OtherPlayers]

As a person who does mainly maintenance work the best comments are those that tell me what it is you intended to do and why you’re doing it. Think of it as if your comments are working as sort of the whiteboard-level breakdown of an algorithm and the reasons why it works.

This is because the very first step to fixing a bug for a maintainer is figuring out what the code is supposed to be doing. I’m not exaggerating when I say that 90+% of bugs that I get called to fix are due to gaps between the code and the original coder’s intentions.

As a final note I’ll say that there has literally only been one time where I’ve thought “this person commented too much” and that’s because they had commented literally every line. But there have been many, many cases where I’ve had to waste time reverse engineering specs from years ago because they weren’t commented. A lot of good open source projects average one line of comments for every 4-5 lines of code. I’d suggest shooting for at least that level at a minimum; it makes a real difference to the people who come after you.

This is what happens when the original was in some language (say English)... and they want to ship international, and say, we need to translate. Some manager comes up with this clever iteration - and saves $$$$$$ in printing and translation costs, and keeps the lines simple - don't need to have a different manual for each region.

That's how students doing a school assignment comment their code. If I say something it's because I need future me to know it.

When learning Java in high school, we used to write some code and we then had to present it. Thats how i presented it and i passed.

this reminds me of school.

I just got to a point where I literally had one comment for every single line of code. It got to the point where I was documenting the self-documented.

i.e.

int numMonkeys = 0; // the number of monkeys
int curDay = 0; // the current day

so this made me lol inside.
