Type-safe, type-unsafe, single-thread, multi-thread, getting Rust and C++ to work together on this project was like using crabs as gears. Michael Gibson and Shuxian Wang brought down the house at #RustUnconf this year with this story, and here it is on our blog. Link below.

#rustlang hot take: We should rename .unwrap() to .or_panic(). (And .expect() to .or_panic_with().) "Unwrap" is a terrible name for the panicking function, especially since we also have things like .unwrap_or() and .unwrap_or_default() which never panic.

From Unit Tests to Whole Universe Tests (with Will Wilson)
From Unit Tests to Whole Universe Tests (with Will Wilson) YouTube video by Developer Voices

How do you test software, if you want to be *really* thorough about it? To answer that question this week we're going as far back as the 8-Bit Nintendo, as far down as the CPU, and nearly as far up and away as Mars. Will Wilson joins me to explore how far you can push testing…

Do NOT call her Taylor Kelce

She. Is. TAYLOR. SWIFT.

Remember how our platform plays #Nintendo games in its spare time?

That's our #fuzzer learning to bomb-jump in #Metroid. Will wrote the story in a real labor of love. Link in first comment.

Happy Friday!

One of my favorite uses of llms so far has been migrating config.

I wanted to play around with hyprland after using i3 for a long time. I pointed the LLM at my nixos config for i3 and it migrated everything without issue

🚀 Had some fun hacking together a new TUI (with @ratatui_rs) to dig into the #FoundationDB #simulation framework!

It visualizes nemesis workloads like:
⚡ Attrition
🌐 Network Splits
⏳ Induced Latencies
