I've just published my new blog post:
"KDE onboarding is good now."
It will be awesome next.
I talk about my history with Linux and KDE and what I've done over the years, going through my work as a documentation contractor for KDE until I reach the current state of KDE onboarding docs.

do you ever find yourself debugging megabytes iostream overload errors, or megabytes of #spdlog template error that doesn't even contain a source location, and wish you had just used printf

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.

Hmm... 🤔
My suspicion why it's "not working" is:
Even though I do `cargo run --release` I've seen, during my investigation of the above compiling-fail-nightmare, that it puts artifacts into `Debug` folder.
So it might be that the program (Whisper.cpp to be precise) runs as a debug build and is just _terribly_ slow. 🐌
Oh boy, the struggle continues... 🤸

People say "fighting the borrow checker" and "getting #Rust to compile" were a pain.
Ok, but HAVE YOU ALREADY TRIED TO BUILD A C++ PROJECT ON WINDOWS!?
You'll probably die trying.
I've tried with VS tools and MSys tools:
- VS build tools: it compiled successfully (but only the previous version of the project, not the latest one), and the executable is 10x slower(!) than on Linux (config: Release)
- MSys: compile fail at 45%
