"How to Optimize Rust for Slowness" – Carl Kadie
#rustlang

#RustLang is great and rock solid. That's why when you build the Rust compiler against LLVM with assertions enabled, it crashes on unmet assertions.

#RustLang jest wspaniały i stabilny. Dlatego jak się zbuduje kompilator na LLVM, które ma załączone asercje, to się wykrzacza na niespełnionych.

Some realtalk and call for help (thread): for a bit over a year, I've been somewhat regularly organizing the domestic #NixOS and #RustLang meetups in #Mannheim and

Just released: embedded-io 0.7.{0,1}, along with its -async and -adapter siblings. These #RustLang crates help #embedded systems abstract over byte data input and output, similar to the standard library's io module.
If all goes as I hope, the embedded-io 0.7.x series can be followed compatibly …

crates.io: Rust Package Registry

Sequoia PGP exemplifies everything that's wrong about #RustLang (don't mean this against Sequoia). It features a bunch of different CLIs, which is a reasonable design.
If Sequoia were written in C, these CLIs would probably be using some shared library. If Sequoia were written in Python, they would probably use a shared Python package. However, it's written in Rust, so every CLI is a huge binary with its own copy of subset of shared Sequoia code, built separately:

-rwxr-xr-x 1 root root 4,7M 10-08 06:36 /usr/bin/gpgv-sq
-rwxr-xr-x 1 root root 21M 10-08 08:38 /usr/bin/sq
-rwxr-xr-x 1 root root 6,9M 10-08 08:38 /usr/bin/sqop
-rwxr-xr-x 1 root root 3,1M 10-08 08:32 /usr/bin/sqv

Sequoia PGP ukazuje wszystko to, co jest nie tak z #RustLang (nie czepiam się tu projektu Sequoia). Mamy kilka różnych binarek CLI, co ma sens.
Gdyby Sequoia była napisana w C, to najpewnie używałyby jakiejś biblioteki współdzielonej. Gdyby napisała była w Pythonie, to najpewniej mielibyśmy wspólną paczkę Pythona. Ale napisano ją w Ruście, więc każdy interfejs to odrębna, wielka binarka z włas…

Who would have thought that creating a programming language for rapidly developing, deploying and abandoning lots of packages would have lead to this…

New article on the blog!
This time, it's about how I optimized an algorithm which turns byte offsets into line/column numbers and UTF-16 offsets.
Most of the performance improvement came from the use of SIMD to efficiently count ASCII characters.
