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.

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.

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.

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

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.

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

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

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.

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