Every so often I come across a Rust idea that refines how I think. This gem from @dtolnay.bsky.social was one of those: > "Statements contain expressions, never the reverse." 1. dtolnay.github.io/rust-quiz/1 #Rust #RustLang

Perps exploit stargazers to build reputation.. some invest years and moneys earning the trust of the people who controlled goods; it's dirty out there sc.cs.cmu.edu/news/2025/09... #scambags #security #supplychain

There's a moron who mistakes thunder for authority and noise for strategy. A con-man who spent years sneering at a Muslim name and now signs off threats with "praise be to Allah" on Easter Sunday, as if history were too drunk to notice the costume change.

Good news! Historically, corruption + war expansion + cryptographic collapse is NOT a classic topping signal.

Years of #clipboard hell: yank in #neovim, pray it survives two #tmux layers + #SSH (It NEVER did) Finally hunted it down with #Claude Code and the fix was monadic: escape the escape, wrap the wrap I should write this up, but for now: I like piña coladas, and getting caught in the rain 🍹

@johnlindquist.com this poem made me smile :) 🐰 One merge to bind them, right-biased and true, Where concatFrontmatter sees defaults through, Property tests hop and validate with glee, No mutations lurk—identity set free! The monoid's laws now unified and bright. ✨ #mdflow #egghead.io

Refactoring boolean logic looks obvious and quietly breaks things. These exercises focus on two tools: - De Morgan's laws to rewrite predicates - Truth tables to prove equivalence github.com/cds-io/logic... Simple tools; big impact on reasoning about code. #programming #typescript #rustlang

If you can't enumerate the cases, you're guessing. Most #programming refactor bugs I see aren't algorithmic. They come from this: "these conditions look the same; let's merge them" Sometimes you can. Sometimes you just shipped a bug. #javascript #TypeScript #rustlang

Rust Patterns from Hardening a Compiler Driver - HackMD

So, here's the context: stable-mir-json is a rustc driver that serializes Stable MIR to JSON. It wraps the compiler, which means the thing it depends on changes constantly, panics on inputs we can't p...

Watching a Vec Grow Up and Move: A Debugging Adventure - HackMD

This tutorial walks through how Rust's Vec reallocates memory when it needs to grow, using LLDB to observe the process step-by-step.
