I recently wrote some thoughts on wrapping Rust libraries for Wasm plus a couple patterns that I use to make wasm-bindgen feel a bit more manageable. No silver bullets here but maybe some sensible defaults (fight me in the comments 😛) notes.brooklynzelenka.com/Blog/Notes-o...

I used to do competitive debate, and my earliest times on the computer were arguing on internet forums. But honestly, I don't enjoy it anymore. I've learned too much about how debate pushes people away from each other and away from understanding, and it mostly makes me sad now.

I am getting better at not arguing with people on the internet. This is major personal growth

langs-in-rust has passed 1,000 stars! ⭐️ It's a list of programming languages implemented in Rust, for inspiration.

One must imagine Sisyphus locking in

Turns out it's not GitHub's fault! Thanks @vcsjones.dev for figuring it out. The LLM bot that Bun is using mentioned me in a prior comment (unclear why) before it was corrected by Bun's lead maintainer. I then received a notification for the next comment in the PR. Bun should fix their bot.

I'm a therapist for thousand year-old warriors / torture victims, and also now one of them.

The push for 100% test coverage here reminds me of safety critical domain requirements around test coverage: that tests are traceable to testing requirements and are expected to cover all functional and failure cases enumerated up-front. It's a domain presenting an extreme form of AI agent safety.

Here's a tragedy of DOGE that most people will never know about, even though it has big consequences: no one is left to coordinate the transition to memory safe systems code. 🧵

Unsubscribing yourself from long-running GitHub issues is self care

TIL “double double” in Canada is a coffee, whereas in California it’s a burger

Proud of my two big articles this year. 2025 was a mixed bag, but these were highlights!

GitHub showing me completely unstyled pages for a couple seconds 🙃

The story of #ruelang so far, by @steveklabnik.com rue-lang.dev/blog/the-sto...

This Yglesias piece in the NYT is horrifically bad. Almost every "fact" it cites is provably false. At best it is cocktail party banter from a pundit who knows nothing of energy. At worst, it was cut/paste from oil industry talking points. So, a rebuttal: www.nytimes.com/2025/12/18/o...

Good reminder that Matt Yglesias and his peers are cowards and losers.

Time to reread

Congrats to "THE" for winning the 1982 Stanley Cup

Re: doxing of Rust OSS maintainers.

Pitch: a Benoit Blanc movie with an Isaac-Chotiner-like character. Chotiner keeps hitting Blanc with tough and insightful questions during Blanc's interrogations and reveals, throwing him off and annoying him, before they provide the insight that lets him solve the case.

Extremely disappointed in the Rust community on this one. Changing your name online should be a very understandable thing to want to do in a trans and neurodivergent inclusive community. For example, having a publicly visible link between your name and deadname can cause real harm. 1/7

As the MIT license says: "THE SOFTWARE IS PROVIDED “AS IS”, WITHOUT WARRANTY OF ANY KIND"

I stopped posting to /r/rust a while ago, and seeing a shockingly large number of pro-doxing or "what did you expect?" type comments on it has only strengthened my resolve not to post there.

Every new terrible GitHub announcement and outage makes me more eager for what @ersc.io is cooking 👀

Congrats to my Oxide friends for officially shipping self-service update support!

Love to be the Rust Guy at work and get random messages about Rust or from folks wanting to find Rust projects to work on.

It's called the social *security* number because it's absolutely secure and will never leak from a database that stores it. /s

👀 (Hey @jamesmunns.com, this might interest you!)

“Heats up” is the right headline to use here given the serious heat dissipation issues of this bad “data centers in space” idea

This is why I care so much about memory safety. These are serious weaknesses that often lead to critical vulnerabilities. For more on why memory safety matters:

The 2025 CWE Top 25 list is out! For memory safety we have: #5: Out-of-bounds write #7: Use-after-free #8: Out-of-bounds read #11: Classic buffer overflow #13: Null pointer dereference #14: Stack-based buffer overflow #16: Heap-based buffer overflow So >25% of the top 25 are memory safety related!

Innovation! My Furby never had a position on Taiwan!

This is Hacklore outdated security concern #3!

Tree's position is nonsense. He can absolutely set up his own PDS if he wants to, but what he wants is for others to be obligated to provide him with free PDS hosting. Hosts have the right to refuse service, and that's not silencing you.

I love getting to work on strange debugging problems and get to learn a little more about a system oxide.computer/blog/cosmo-sp

Includes a new "Optimizing Build Performance" section added to the Cargo Book!

Slowly becoming more of a baseball statistics sicko by doing stats for my casual softball league.

With all the speculation and theorizing about the impacts of LLMs on psychosis, it’s important we have case studies like this, and more research beyond it.

This is right. The 14th Amendment is unambiguous, and if the Court pretends to have the authority to override the Constitution's text, the Court proves itself illegitimate.

Woah, ROUTINE released! I was still in undergrad when I saw the first trailer for this. I'm 30 now.

After the Rust-bashing from the last outage, I'm glad Cloudflare called out the Rust version of the component here didn't have the bug at all.

Steve is right. Arenas can be good for specific workloads, for example when lots of data shares similar lifetimes, but not all workloads look like that!

Configuring Ghostty is easy. Here's mine: gist.github.com/alilleybrink...

I keep seeing people discover that labeling or user-managed blocklists at scale are *very difficult* do well. It's a mass crash course in the challenges of Trust & Safety work, and in the case of this AI labeler it's also a massive legal liability for the creators.

one thing i learned in tokyo is that i think street parking should be illegal everywhere

Ominous words from the court jester
