Project mention: Dev log 20: Deleting 180k lines and chasing socket leaks: A week in the OSS trenches | dev.to | 2026-09-06
Rust Compiler: I opened PR #162123 to report unsatisfied opaque item bounds instead of a generic type mismatch under the -Znext-solver. Contributing to the Rust compiler is always a "hold your breath" moment, but it's the best way to learn how the magic happens.

Interesting proposal, but with severe risks: becoming dependent on a single specific compiler and rustc could include malicious code that isn’t obvious to an outside auditor. See https://aeb.win.tue.nl/linux/hh/thompson/trust.html Ken Thompson demonstrated this.
But what will the future of RustPython be? https://github.com/RustPython/RustPython/
Major shifts like this are complex, not so only from a technical perspective but even more because a lot of humans with different opinions are involved. But radical changes are sometimes needed to be innovative again.

Project mention: What's the best programming language for coding agents? | news.ycombinator.com | 2026-08-10
Ive been amazed at how well LLMs are at writing Gleam[1] and Lustre[2]. Compared to a mainstream language, there is basically zero gleam code in the training data.
I have no evidence to back this up, but I suspect that languages that are good for humans[3] will be good for LLMs. Compiled, strongly typed, statically typed, immutable, pure functions, pattern matched, memory safe, etc.

rspack Description: A modern, rust-based javascript compiler that replaces webpack. What we like: Rich feature set that attempts to have feature parity with webpack; it's part of a growing ecosystem that appears well-maintained. What we don't like: It supports similar complexity in its configuration due to feature parity with webpack

foundry
Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.
Project mention: Contrarian View: Vyper 0.3.10 Is Overhyped – Solidity 0.8.20 Is Better for Smart Contracts in 2026 | dev.to | 2026-04-29 -
-
farm Description: Another rust-based bundler What we like: Excellent documentation; has been under active development for quite some time; if its history is a reliable indicator, it will (hopefully) be reliably maintained for years to come. What we don't like: The speed comparisons on their website feel dishonest - we don't like that it claims to be faster than everything but doesn't offer direct comparisons for tools like bun. (Note: we're not commenting on the accuracy of their comparisons - only noting that the comparisons aren't presented in the best light)
