A story about never ever giving up...❤️‍🔥

After several weeks, questioning my life choices, I've finally figured out why my #Whisper #SpeechToText system had been so slow on #Windows:

It was because apparently the #Rust-FFI wrapped #CPlusPlus code (Whisper.cpp) didn't compile with AVX and AVX2 enabled ( #SIMD!). I've tried it on two Windows machines (both AVX-capable). On one of the machines, with #Linux, it has successfully detected AVX/AVX2, though and has run fast.

Ok, I have to correct myself:

Compiling any C/C++ project on Windows is an absolute clusterfuck!

I've now almost spent more time trying to compile my program for Windows than writing the actual code for it - let that sink in!

Hi, are there any followers here related to #CERN interested in #CPlusPlus ? My scheduled trainings in October still lack participants and thus might be cancelled.

So sign up or spread the word!

Side note: I would LOVE to be able to use C++'s native tagged unions: std::variant. But defining something recursive with std::variant is impossible because you can't forward declare an alias. I want to do:

declare_alias Value;
using String = std::string;
using List = std::vector;
using Value = std::variant;

But there is no way to do that. You can only forward declare classes, structs and functions. So I'm stuck wrapping the variant in a class. #cplusplus#cpp

I'm stuck trying to decide whether to implement my own hash table, or use an additional and unnecessary level of pointers with unordered_map

C++17 gave us std::vector, std::list and std::forward_list of incomplete types (HOW DID IT TAKE THAT LONG), but from what I can tell, not even C++26 will have std::unordered_map of incomplete types :(

Of course in #Rust, vectors and hash maps and everything else just works with recursive types no problem

#cplusplus#cpp

C++ has the most bloated yet anemic standard library, the whole library is an over-engineered mess but lacks even the most basic functionality that's useful in the real world such as "format this timestamp as a ISO 8601 time" or "parse this ISO 8601 time to a timestamp", it's infuriating #cpp #cplusplus #programming

Why did IEEE specify sqrt(-0) to be -0?! That's … surprising when applied to the interpretation of -0 in the context of complex numbers:
sqrt(complex{-0,+0}) is complex{+0,+0}.
And also pow(-0, 0.5) is +0.
If anything sqrt(-0) should be NaN, but why -0?

I added hot reloading of C++ gameplay code to my game :D

This is possible because "engine" code and "gameplay" code is split into different shared libraries. So when you hit F5, it compiles a new shared library for the gameplay code and loads the new one (as well as reloading all the assets etc).

I was able to use precompiled headers to significantly speed up recompilation! A full rebuild of all the gameplay code used to take 4.5 seconds, on my laptop. Now that I made it pre-compile the engine headers, it does it in 1.6 seconds.

I've tried precompiled headers before and struggled to get real speed-up, but I guess this is literally the perfect case for it; every gameplay source code is gonna include the exact same engine library header 😊 #cplusplus#cpp
