We are hiring Rust devs to work on building out a programming language (BAML) with crazy new, useful features for making AI pipelines. Our entire team is senior+ engineers. We are a team of 5. We work hard and in person in Seattle. We accept new grads. The interview is not leetcode, but a 1-week work trial. Send me a DM on X or LinkedIn or email aaron @ boundaryml dot com if interested.

The translate feature on this app is incredible. I just saw french, spanish, chinese and japanese all in the same thread

The combo of everyone starting to use more Rust + everyone also shipping 7x more code means CI infra companies are printing money. Do you want to ship fast? Or have your program run fast? Thats what big corps are grappling with

Friendship ended with AOT (attack on titan) Now AOT (ahead of time compilation) is my best friend

if only someone were building a programming language for this new era
DHH is fundamentally right about Rust. For context, Vercel has been undergoing a Rust-ification (carcinization, technically 🦀) for a while. One of the first projects we migrated was Turborepo, from Go to Rust¹. The migration completed, but the RoI was actually quite controversial internally. While Rust was in our eyes better for low-level OS access, something crucial for a build system like Turbo, the human migration costs were very sustantive. Go is very fast. It's beautifully designed. It's easy to iterate on. We were very conflicted about the migration, because it was *humans* writing the code, *even if we knew Rust was a better choice*. The calculus has now changed. What's "best for humans" is no longer necessarily "best for business". FWIW, it's also quite unlikely that Rust is the end-all-be-all toolchain. I'm quite certain there's greener pasture ahead, because Rust itself was designed before the 'supersonic tsunami' of agents hit. ¹ https​://vercel.com/blog/how-turborepo-is-porting-from-go-to-rust

javascript really is the zombie we keep dressing up first typescript then effect now real types in typescript
The first step is types. We're adding a TypeScript-compatible type checker to Bun. It’s the best shot ahead-of-time compiled TypeScript has at beating languages like Go on memory and speed.

we can consider most software users have direct access to as open source from 2026 onwards

The next benchmarks will be making videogames or videos. It is so easy to get a vibe check for how much the model understands the world and complex systems this way.

this is one of the most dogshit websites i've seen, and they're worth $98 BILLION. why are there like 15 diff hues of purple, blue and... green? why does the video look like it was made in Microsoft Powerpoint?

opus 5.5 was so good they had to kill gpt-6-sol after 2 weeks.

Ai generated videogames became viable just now in 2026

What if the labs are just using reverse psychology to make people accept AI
I love that pop culture now sees how ridiculous doomers are 🤣

animations are a semi-solved problem now with opus-5.5. They seem high quality enough and viable. 100 new startups / small businesses will be born due to this AI model.
Claude Opus 5.5 has the best visual design of any model I have tested so far
