If CPU/GPU execution speed is the goal while simultaneously code golfing the source size, https://halide-lang.org/ might have come in handy.

The premise of this website and articles like https://yosefk.com/blog/how-profilers-lie-the-cases-of-gprof... just show that the authors are using the wrong tools. It is nowadays relatively easy to also look at off-CPU time when profiling with perf (e.g. https://github.com/KDAB/hotspot/?tab=readme-ov-file#off-cpu-...). The idea is to use sampling for the on-CPU periods and then combine that with the off-CPU time measured between context switches. VTune also supported this mode for many years.

Project mention: Exploring biphasic programming: a new approach in language design | news.ycombinator.com | 2024-07-02
I'm going to hijack the mention of ML to share xbyaku, a c++ library presenting a DSL for assembling machine code at runtime (useful for JIT).
It's used by some of the pytorch back ends.
https://github.com/herumi/xbyak
Example use: https://github.com/oneapi-src/oneDNN/blob/main/src/cpu/aarch...
I learned about these through a blog post about speeding up pytorch on ARM: https://pytorch.org/blog/optimized-pytorch-w-graviton/

Project mention: You can help Anna's Archive by seeding torrents | news.ycombinator.com | 2024-06-13
I wonder if there is any benefit to using something like DwarFS (https://github.com/mhx/dwarfs) for something like this.

ultimatepp
U++ is a C++ cross-platform rapid application development framework focused on programmer's productivity. It includes a set of libraries (GUI, SQL, Network etc.), and integrated development environment (TheIDE).
Have you ever tried U++? I haven't used it beyond quick and dirty testing but has a decent GUI builder and is a full C++ IDE.
