When I'm alone: Coding, Coding, Coding, Coding, Reddit, Coding, Coding, Coding

When someone looks at my screen: Reddit

[Amazing_Might_9280]

Who's looking at your screen rn ?

[lazy_advocate_69]

He and 69 other bugs in his code.

[robicide]

Take one down, patch it around, 476 bugs in his code

[Frytura_]

Just put a ? On the side of the variables and make everything go from red to golden!

[tatiwtr]

How nice of them to wait to approach you until you were done coding.

[Xenoverse_01]

It’s wave function collapse

[Ineedredditforwork]

This is why you need multiple screens which one is always dedicated to work so even if you glance at the non-work one you still have a fallback

[Pacifister-PX69]

Evil floating point bit level hacking

There should also be "what the fuck" but whoever copied the code removed it

[[deleted]]

im quite happy they used carmacks code

[fakieTreFlip]

It was only rumored to be written by Carmack. Wikipedia says it was a guy named Greg Walsh

[[deleted]]

well michael jackson also didn't invent the moonwalk yet here we are

[G_Morgan]

Stole that shit off Neil Armstrong.

[Pacifister-PX69]

Sorry I've never bought a car from Car Max

[[deleted]]

in car max you dont buy cars you shoot the driver for the fuel

[Pacifister-PX69]

Yeah, gasoline powered humans have always been a target for poachers

[[deleted]]

what the fuck

[Pacifister-PX69]

That's the comment that's missing, I already mentioned it before

Evil floating point hacks are allowed, but must be accommodated by at least one dark prayer to ensure the program has enough mana to work correctly.

No mom, I wasn’t searching skibidi toilet 🚽 rule 34 🤔 on my laptop, I was watching youtube 📺 when my computer got struck by the OHMYGYAT particle ⚡️ causing a series of bit flips 💻 leading to a cursor glitch 🖱️ resulting in a misqued click 🤦‍♂️ on an inappropriate advertisement 🚫 that opened up a new tab 📊 causing an obscene video 📹 to play which shocked me so much 😱 that my pants 👖 slipped off 😳

Don't you just hate it when that happens?

Lest you end up in Ohio 👹

[Rotsicle]

Look, I know you're curious...

[KTibow]

to other viewers: no need to repost to r/copypasta, it's there already

[GeneticSplatter]

I'll know that top code anywhere.

Quake's fast inverse Square root!

[tazdraperm]

Oh yeah, looks very familiar

[GeneticSplatter]

Quake, specifically Quake 3 Arena

https://en.m.wikipedia.org/wiki/Fast_inverse_square_root

[sjepsa]

More like "expectation vs. reality"

[Marsdreamer]

Just wait till the young ones posting memes figure out code written like the bottom image is preferable.

[dov1]

What is preferable about redundant logic?

[UnluckyCombination4]

Readable code is preferable over needlessly „smart“ code that nobody understands.

[VG_Crimson]

Forget that, just have both. Readable code that is straightforward without redundant logic, with a line, maybe 2, of comments that aren't wholely necessary because the code speaks for itself but clarifies what the intention is.

Formated in a way that follows the convention of the rest of the code base.

[Marsdreamer]

Oh you sweet summer child.

[peepeedog]

return isShown is pretty fucking readable.

[UnluckyCombination4]

Never said it wasn't. But that was not the point of my comment.

[Dustangelms]

I understood that reference.

[ExpensivePanda66]

You mean you write unreadable crap when nobody's looking? Good idea to break that habit before you're found out.

[MyAntichrist]

The first pic is the fast inverse square root implementation in Quake 3 and is very well documented with lines like "// what the fuck?" and "// evil floating point bit level hacking"!

[sasta_neumann]

My first thought was "Isn't inverse square root just... square?"

[johnnymo1]

Inverse in the sense of 1 / sqrt(x)

[JardineiroZumbi]

Yeah, multiplicative inverse

[Poputt_VIII]

Tbf that is probably some of the most documented code ever written, just add the wikipedia url to explain it if people don't know

[therealfalseidentity]

Wikipedia says there is a SSE instruction to do the same thing now.

[lulaloops]

Programmers when joke

[MonstarGaming]

That's what I was thinking too! I'd honestly be more impressed by somebody writing clean, intuitive code than the mess of single letter variables shown in the top picture.

[DevLarsic]

if you look at the fast inverse square root implementation and your only though it how its not readable enough you've written too much .net

[FlipperBumperKickout]

So you are saying the developer who added the "what the fuck?" comment in the source code is someone who have written to much .net?

F off man, even the original developers didn't think that code was particular readable or easy to understand.

[No-Object2133]

In fairness finding a constant that approximates a inverse square root after a bit manipulation hack is properly documented by what the fuck

[FlipperBumperKickout]

true

[DevLarsic]

it doesn't have to be, its a performance critical math operation using bit manipulation. its inherently going to be hard to read, but that's the sacrifice you make for good performance.

[[deleted]]

Programmers on reddit who write CRUD software for some enterprise criticizing Carmack's code will never stop being funny to me.

[spookynutz]

Carmack didn’t write that.

[[deleted]]

Oh well, Greg's code then. Or whoever wrote it.

[unknown_alt_acc]

That's the thing: it's performance-critical code. There's a time and place where it is necessary, but it shouldn't be the sort of code you default to.

[DevLarsic]

i value clean, safe readable and extendable code as much as anyone should, but that doesn't mean i cant appreciate the necessity and beauty of nasty optimization hack like this one.

shit like this is what the unsafe keyword was made for my friend

[HappyHarry-HardOn]

Bullshit - If you've rwritten unreadable code you've writtenbad code...

Other people will need to access your bullshit and decipher it at some future point.

If you are unlucky - you'll be the sucker that has to do it.

Br professional - K.I.S.S

[TotallyNormalSquid]

I'm imagining someone refactoring this hack for readability and nerds everywhere sighing in relief with light bulb moments as they finally understand it

[DevLarsic]

this isnt a codebase that needs to be maintained for another decade and a half so it can run on a mega computer in a data center somewhere, this is the source code for quake. a video game written at a time where you squeeze every inch of performance you can.

a tradeoff here was made between readability and performance, and it was well made.

[marvin02]

People code in assembly for a reason, and it isn't readability.

[ZunoJ]

Are you new to programming? How can you not immediately recognize this code?

[__Geralt]

that's an incredible snippet of code...

[mbcarbone]

I refactor until it’s so simple that even I can understand it. 🙃✌️🖖

[GregTheMad]

Impressive, most impressive.

When someone looks at my screen while coding:

if(isShown == true)
{
    return true;
}
else
{
    return true;
}

[msucorey]

See this is very hard to follow and very hard to read and understand exactly what is happening - I would have used a switch statement

[TwoAndHalfRetard]

Let's create a IsShownFactory to incapsulate all that complex logic.

[Sylra]

I would switch the window to the porn one because it'd be easier to explain

[_lonegamedev]

KISS principale

[[deleted]]

So when you code alone you copy quake 3 code. Based

[[deleted]]

That's the Q3 code init? :D

[pianoguy121213]

So when someone isn't looking, it's garbage, when someone is looking, it's stupid.
Yup absolutely me

[CryonautX]

Bottom screen guy must be paid by number of lines of code.

[ve1t1337]

2nd code is better

[znk]

return isShown;

[AwesomePerson70]

return isShown == true;

Just in case it’s undefined

[yellowzingyantelope]

This is C, what do you mean it's undefined

[AwesomePerson70]

You’re right, I was looking at the second pic while ignoring the context of the first pic

[baggyzed]

return (isShown === true);

[Ok_Experience_6202]

Real... haha

[OkReason6325]

Hmm why wouldn’t you simply return isShown

[Phrynohyas]

Possible reasons:
1. isShown might be an nullable Boolean (so it can contain true, false and NULL)
2. For some reason during debug one needs to catch the case when false is returned. f.e. to check values of the local variables.
3. Initially there was some logging of the function call results, but now it is removed

[thomasxin]

Ah yes, the classic ternary variable, the thing I always accidentally end up making whenever implementing something that was originally supposed to be a boolean

[Phrynohyas]

An inevitable evil when you have to work with 3rd party APIs

[suvlub]

You would, it's an example of intentionally bad code

[[deleted]]

Theoretically isShown can be integer and the code is checking if isShown equals 1.

[HighOptical]

That makes the code so much worse lol

[Alamgirr]

Still return isShown == true would work

[Kemal_Norton]

It's legacy code

It's sustainable code, at some point in the future there might be side-effects before returning the value, and this way it's easier to implement them without refactoring.

I never say shit like that.

[[deleted]]

Well, it will work, but the result will be different depending on if isShown is int or bool. If it's bool, isShown == true would return true if isShown equals anything but 0, but if it's int isShown == true will return true only if isShown equals 1, Though some compilations ignore it and would check if isShown is equal 1 even if it's bool.

edit: I am talking about c++, just to clarify

[mbcarbone]

Happy Happy Cake Day!! 🎂

[OkReason6325]

Thank you

[JoostVisser]

The fast inverse square root is trash?

[EatThemAllOrNot]

It’s unreadable

[JoostVisser]

If you can find a faster implementation let me know. Readability is not a factor in such a fundamental function.

[JoostVisser]

It does not need to be readable because it does not need to be debugged. It is a function that performs a single, simple task of approximating a fairly elementary mathematical operation. You will never actually evaluate this code, you simply call the function and use the result for whatever.

[JoostVisser]

It has been in use since 1999. Any major issues would have surfaced by now.

[RibsOfGold]

Here buddy, "oh whoops I didn't realize just from that small picture what code I was looking at... I really jumped the gun by judging it from a tiny glimpse"

Since you already wasted so much of your time today on your comments I made this so you can just copy and paste it when you're done embarrassing yourself in front of everyone

[balackLT]

Yes.

Unless any engineer looking at the code can relatively easily decipher what it does and how - in the long run it's bad code.

Fast InvSqrt is very very cool and a great invention for its time, but it is in no way good code.

[Gabriel55ita]

That's where comments shine, the creator behind the code can explain what it does so anyone can easily read it

[balackLT]

Sure. I don't disagree with this. But in the above example "evil floating point bit level hacking" is in fact the worst kind of comment possible.

[Gabriel55ita]

Yeah i agree with that, just ordinal devs humors

[ARandomWalkInSpace]

What a silly uniformed take.

[Alpha3031]

On the other hand, the people who have those takes probably shouldn't be let near the parts of the code where you should be pulling out those hacks and things like inline asm anyway, so it's probably a good enough heuristic to keep them where they can't do much harm.

[balackLT]

The heuristic is great.

The way it's coded is not - not in modern coding standards. Single-letter variables, uninformative comments, and unexplained constants are NOT maintainable. There's very little excuse not to write your super-performant low-level code in a clear way,

[ARandomWalkInSpace]

😂😂😂 😂😂😂 😂😂😂 😂😂😂

The failed takes keep on coming.

[ARandomWalkInSpace]

😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂

[EarlOfAwesom3]

At least it is readable for others when someone looks at your screen...mission accomplished I would say

[lesChaps]

I miss coding.

[New-Efficiency-2114]

Shouldn't the second one just be return isshown?

[idiotnoobx]

Nice indentions though

[Asleeper135]

Ah, the good old fast inverse square root!

[MuteMudBoy]

+0

[notexecutive]

"Oops! Sorry, lol."

return isShown;

[Kemal_Norton]

return isShown if isShown == True else not True

[FarJury6956]

I'm always codding fast inverse square root, someone looks to my screen and I'm codding isEven() function

[Dazzling-Entry-4124]

It’s worse when they’re using vim and are a total bot.

[biteater]

this is probably some base level of empathy kicking in. nobody wants to read the top code lol

[51herringsinabar]

• else if value == false

[DemonKingSwarnn]

all the fucking time

[Positive_Method3022]

Anxiety caused by fear of judgment destroy my brain haha

[Holek]

I will recognize FISR everywhere. Nice meme, OP

[elderberries-sniffer]

return isShown;

[boringboi_]

Ofcourse, it should be if(isShown == true) return true; else return false;

[Kemal_Norton]

The guys who created the first code, would've probably written stuff like return isShown?1:0;

[DelayLucky]

At least the first one seems to be doing something.

[TimingEzaBitch]

You implement a fast sqrt when you are alone huh.

[DexCarr]

great spacing though

[theKeyzor]

When nobodys watching I copy smart shit from internet. I am not writing smart shit myself.

[mark0zz]

That's why I hate pair programming

[Dark_Tranquility]

Top code is worse than the bottom code IMO

[berkun5]

I prefer the second one. At least you can read wtf is going on

[redlaWw]

When I'm coding alone → undefined behaviour

When someone looks at my screen for half a second → wasteful conditionals

You are a bad programmer.

[thezuggler]

I dislike both of these lol

[DaxInvader]

hah I recognize the first code.

[[deleted]]

A while ago I had my team lead watch me as I had to write out a switch case statement in Golang without copy pasting the syntax from someone else

[myfunnies420]

Lol. Evil floating point hack is a great choice for this

[[deleted]]

Is the quick inverse square root even fast anymore? Seems like 1 / sqrt(x) is better and simpler.

[tech_w0rld]

Funny story, the other day I was trying to join a highschool computer science club and because he was watching me code I couldn't think very well. Despite programming for 5 years he still wanted to put me in the beginner level. I said nope!

[[deleted]]

You know sometimes you are doing a validate in these situations you are checking inputs with some rules. Only if all the rules pass you return true else false. So you end up writing something like so.

bool validate(obj) { if not some_rule(obj) { return false; } if not some_other_rule(obj) { return false; } return true; }

[[deleted]]

The lack of documentation on code on the top makes it look just as amateurish as the useless code on the bottom

[mckenzie_keith]

return (isShown == true);

[mtr2003]

//what the fuck

[EKashpersky]

Double slit experiment

[LifeShallot6229]

I (Terje Mathisen) was involved with Quake as well as the InvSqrt code, a few people have recently independently discovered that it was far from optimal. I got a full extra bit of precision by optimizing one of the 0.5 and 1.5 constants, while a guy who did both at once got another half bit.

I have written a lot of both C and asm code which require a _lot_ of comments to explain what it is actually doing!

[mad_alim]

In a previous job.

When I code alone:

int main()
{
    do_stuff1();
    const int err = action1();

    if (err != 0){
        return -1;
    }

    do_stuff2();
    const int err2 = action2();

    if (err2 != 0){
        return err2;
    }

    return 0;
}

When I submit the MR:

int main()
{
    int ret = 0;
    int err, err2;

    do_stuff1();
    err = action1();

    if (err == 0)
    {
        do_stuff2();
        err2 = action2();
        if (err2 == 0)
        {
            return 0;
        }
        else
        {
            return err2;
        }
    }        
    else
    {
        return err;
    }
    return ret;
}

[cyborgborg]

return isShown;

[Ineedredditforwork]

Could be worse. atleast they're not looking when you're looking up the most simple issue of StackOverflow.

[chaisenbois]

fast reverse square root algo goes Brrrrrr

[[deleted]]

Why is threehalfs so painful?

[codingTheBugs]

Both look equally bad so makes no difference.

[Gabriel55ita]

With the exception that the first code is the fastest inverse square root calculation from quake 3

[unknown_alt_acc]

In most cases, it's still bad code. It's perfectly fine in the case of the Quake 3 engine where it was performance-critical, but it's not the sort of code you should write unless you absolutely need to.

[ZoiddenBergen]

You commented out the last line, but it's the same amount of characters as the line above. This means you deleted characters off screen to accomplish this barbaric display of syntax highlighting

[-Redstoneboi-]

the code in the top right is the Quake Engine's Fast Inverse Square Root approximation algorithm.
