TIL in C++ `BasClass&` can be created from a `Derived&`, thereby it does dynamic dispatch through the vtable instead of the reference being a guarantee that static dispatch is enough. Huh. This proves to be a mild issue with my C++/Rust interop crimes.

People don't change: in my Rust/C++ interop crimes I wanted to build an enum over "one-shot Request" vs "multi-response Request" even though both are just a C++ Request object at its core. An epiphany: this is what I always do in TypeScript as well! No wonder it felt so familiar and safe!

So lately I've been having obscene amounts of fun during absolutely hair-brained and -raising FFI crimes between Rust and C++. "Look ma, no C ABI!" Just going in raw, binding to C++ ABIs, inheriting C++ classes, creating C++ template instances like std::function's, all that good jazz direct in Rust.

So I'm taking a choir conductor camp, and in the same music camp is a man who is a total doppelganger of a coworker of mine, like not just looks similar but they really look like a clone sometimes! Turns out: they're identical twins. I guess that explains that.

So in other news today, I had a terrible/fun time with figuring out printing of WebComponent elements in response to a user button click without blocking the event loop! Can't use print() because it blocks, can't use iframe.src URL because it loses DOM state. Painful world out there!

I'm *very* excited to report that we got initial funding and have hired our first Rust maintainers! RustNL's Rust Maintainers Team starts out with two full time maintainers, one intern, and five part-time maintainers, now stably employed to continue their work on Rust! 🎉 rustnl.org/maintainers/

Screenshot of the website, listing the eight team members: Oli (full-time), Waffle (full-time), Tiffany (intern), Mara (part-time), Jana (part-time), Nia (part-time), Bjorn (part-time), and Folkert (part-time).

I'm excited to share what I've been working on with @erikjee.bsky.social: RustNL's #rustlang Maintainers Fund! Many people and companies contributing to Rust, but there are fewer and fewer paid positions for general maintenance (reviews,cleanups,etc). We need to fix that. bsky.app/profile/rust...

My #JavaScript SoA adventures are bearing fruit: a test creating a data flow graph of 750k nodes, 250k graph entry/exit points ("inputs"), and who knows how many inputs not participating in the graph, it takes <400ms to run. That's ~400ns per node or input, which is pretty cool I think!

Meh, none of my three talks made it past the sieve :D And I had such a banger topic line for one of the talks as well: "Data race you to UB!", I was really looking forward to giving that one. Better luck next time I guess!

After carefully reading and ranking a record number of 185 submissions from 148 speakers, we finally finished the talk selection for RustWeek 2026! I'm *really* excited about the lineup! Check it out here: 2026.rustweek.org/blog/2026-02... Don't forget to buy your ticket! See you in Utrecht!

ある親切な日本人がフロリダの自然に大変興味を持って、英語があまり出来なかったけれど一人で旅行することにしました。着いたら彼が皆に自然ツアーのことを尋ねて、無視されなっか場合必ず「ありがとう！ありがとう！」って言いました。 やっとあるツアーをやってくれる人を見つけて、2人で沼を見に行きました。沼に着いたらガイドは指差しで興味深いな所を指さして、日本語で「ありがとう」って言いました。日本人が近くに見に行きました。 わにでした。

Fun Finglish thing: "service" seems to conjugate to "servikse-", so it sounds like people are talking about the cervix. "Our cervix did great work in driving our EBITDA up!"
