#rustaceanstation — Public Fediverse posts

I'm looking for a remote Rust/Elixir role (EU-friendly timezones, US East is ok).

I have 7 years of #rustlang, 9 years of #elixirlang, 20+ years of #linux.

I have over 20 years of experience as a professional developer, and I've been working remotely for 12 years, during which I helped US and EU companies build reliable software.

On the side, I've been developing #asciinema, the best tool to record and stream your terminal sessions. I talk about it in the context of Rust in this #RustaceanStation interview: https://rustacean-station.org/episode/marcin-kulik/

My current contract ends soon, so this is a great time to talk! I'm open to both full-time roles and short term contracts.

Boost please!

The #RustaceanStation podcast just released an interview that Luuk van der Duim did with @DataTriny and me about #AccessKit at #RustWeek: https://rustacean-station.org/episode/accesskit-with-matt-campbell-and-arnold-loubriat/

My friend and I are doing a presentation on #WASM. Part of it is taking a program (a sudoku solver) written by a friend (who, for this implementation, used #GeminiAI). The plan was for my friend to re-write it in #C, which can be compiled to WASM; and for me to write it in #RustLang, which also can be compiled to WASM. To keep the programs the same we couldn't optimize the actual algorithms, but we could optimize anything else. So, for instance, no making a linked list of empty spaces; but inlining cell lookup is fine. #Optimization

On my machine, my initial implementation (again, in Rust), was 50% slower than his implementation in C (running over the same puzzle a million iterations).

I started to optimize using #XcodeInstruments. My first time with this tool. Just didn't understand it well enough. I tried many optimizations: a one-dimensional array backing the board instead of an array of arrays; inlining particular functions; finding places where I knew it couldn't fail and removing checks. Things like that. Sure, I made it a little faster.

Then listening to #RustaceanStation I learned of a specific feature. A simple feature. In my code, I represented board cells with a simple enum, almost an exact copy of Option, but instead of None, it is Empty; instead of Some(x), Digit(x). The new feature is NonZero. Option<u8> in Rust is two bytes. Option<NonZero<u8>> is one byte (because the u8 can't be 0, Rust can use the 0 value to mean None)!

I applied exactly that one change to my implementation and that optimization, all by itself, made my program faster than his C implementation.

I was completely surprised, and very pleasantly.

In a #RustaceanStation interview, Lars Bergstrom mentioned that the #Android team had looked at using #Swift as a memory safe native language to complement C++ (where finally #Rust was chosen).

I would love to see the alternate reality in which that came to pass.

Imagine if you could write all your mobile apps in Swift… just Swift. 🥹

#cpp #rustlang

I find it kind of amazing there's a podcast about a programming language (https://rustacean-station.org/) these days. You would think what language used would matter less than what your program does, but programming is a way of creative expression. It's an interesting listen.

I am a repeat offender now: Here is my second interview with #rustaceanstation:
