Not a financial expert however, Citadel is a market maker rather than just a hedge fund like Melvin. Money is lost when a retail investor holds onto their shares not just when the stock price rises.

I'm a little short on time so I didn't read through all of it but, comptime generics sounds similar to how rust compiles generics and comptime parameters are similar to const fns although zig appears to have more control over what

I completely forgot stdout handle is in the PEB! Thanks! After learning how the windows x64 syscall calling convention works I got it working on win10. https://i.imgur.com/ErHU7Kr.png https://github.com/mcou

Very well optimized inlined functions? I didn't actually check the zig std source. I was referring to what I was seeing in radare2 :)

Yeah my choice of words wasn't great. It seams as if the zig std acts as a macro rather than a wrapper. That could just be the aggressive optimization though

@Edit2 I saw that, and that's pretty cool in regards to how the zig std is a wrapper rather than a rewrite. Although, if we were optimizing for size in this case it might be more optimal to have only one entry in the import table :D

Between a 40b strcmp method (If I had/if it was more widely supported I could use sse4.2 strcmp) and ~74b of resolving said exports a couple syscalls sounds pretty nice provided the context switch isn't more expensive than resolvi

I thought of that but couldn't figure out how to get the syscalls for my system and the assembly around it. Being on win10, kernel32 links to api-console-... and I haven't been able to find it on my system. A few online download

In order to get that to 1Kb you would probably have to drop the `.idata` section and resolve syscalls from the PEB like I did.

Ah, yeah, I wasn't trying to shrug off the usefulness of zig, sorry. I think when it comes to compile size zig does it a bit better due to it's smaller std although, when compiling rust with just a link to libc and a printf call

Just for fun, the compiled rust exe has 480 non-zero bytes, the zig exe had 512 bytes.

I couldn't get it working and was familiar with the `llvm_asm!` syntax. Although, I may have to go back and switch it around again.

I linked these guys here https://github.com/pts/pts-tinype . They managed to do something similar with the PE headers, and I might have to try that next although I'm doubtful win64 exes are permitted to run if the

This is my attempt at making the smallest exe with rust for windows using the msvc toolchain. If y'all have any pointers how to get it smaller let me know :)
