See cooldowns.dev for up-to-date information on cooldown adoption across various languages and package ecosystems.

TL;DR: I’ve turned my April post on Brocards for vulnerability triage into a more permanent website. You can now link to each brocard directly, like this , without having to worry about link rot 1 .

Update 2024-01-12 : Ken Shirriff has an an excellent blog post on why “cargo cult” is a poor term of art.

Dear GitHub: no YAML anchors, please
This was a good thing . YAML anchors in GitHub Actions are (1) redundant with existing functionality, (2) introduce a complication to the data model that makes CI/CD human and machine comprehension harder, and (3) are not even uniquely useful because GitHub has chosen not to support the one feature (merge keys) that…

Things I hate about Rust, redux
Two years ago, I wrote a post with a handful of grievances about Rust , a language that I then (and still) consider my favorite compiled language.

Hiding messages in x86 binaries using semantic duals
This is a quick writeup of a steganographic tool that I threw together: steg86 . It uses a quirk of the x86 instruction encoding format to hide messages in pre-existing binaries with no size or performance overhead.

In 1582, under the inter gravissimas papal bull, the Catholic world transitioned from the Julian Calendar to the Gregorian Calendar . This new calendar shortened the length of the year from 365.25 days to 365.2425 , a reduction of just 0.002% .

LLVM internals, part 4: attributes and attribute groups
This is the last post I plan to do on parsing LLVM’s bitcode, at least for a while. I’ll keep working on the various libraries that I’ve started under the mollusc umbrella, but they won’t be accompanied by regular posts anymore — I’d like to refocus on writing smaller, less dense (read: lower-pressure) posts for a…

Writing and publishing a Python module in Rust
This post is a quick walkthrough of how I wrote a Python library, procmaps , in nothing but Rust. It uses PyO3 for the bindings and maturin to manage the build (as well as produce manylinux1 -compatible wheels).
