On the new FrontierCode [1] benchmark (ie graded from an OSS maintainer's perspective of "would I merge this code?") - Opus 4.7 xhigh: 5.2% - Opus 4.8 xhigh: 13.4% - Fable 5 xhigh:…

I agree in principle with the math. But I believe that in reality if revenues don't show up quickly, then lenders will just restructure the debt and defer the payback period. Simil…

Dario (the founder) has a phd in biophysics, so I assume that’s why they mention biological weapons so much - it’s probably one of the things he fears the most?

claude swe-bench is 80.8 and codex is 56.8 Seems like 4.6 is still all-around better?

@deno team, how do secrets work for things like connecting to DBs over a tcp connection? The header find+replace won't work there, I assume. Is the plan to add some sort of vault c…

I needed Mac / win/ Linux / iOS / android for dioxus dev, so I built my own in rust. https://skyvm.dev/

I started building something for the dioxus team to have access to mac/linux persistent and ephemeral dev envs with vnc and beefy cpu/mem. Nobody offered multiplatform and we reall…

WGPU for render, winit for window, servo css engine, taffy for layout sounds eerily similar to our existing open source Rust browser blitz. https://github.com/dioxuslabs/blitz Mayb…

I work on Dioxus (Rust WASM framework). WASM for frontend, at least, has been held back by fundamental tools like bundle splitting, hot-reload, debugger symbols, asset integration,…

The browser UI will likely be more of a cool demonstration of the project instead of the end goal. We want blitz to exist to help make it easier to build stuff like lightpanda. The…

That's why Rust was introduced into Firefox piece by piece. The goal wasn't to rewrite firefox in Rust - just to migrate the scary bits over to a memory safe lang. You can feel a l…

I mean you can opine about how Rust isn't suited for browser development, but as someone building a browser in Rust, I think it's just fine. If anything, Rust has been really shini…

It seems like the economy is on a “K” shaped flywheel. How much worse can the economy get for the regular worker before the systems just pops? We’ve put so much speculation into an…

I think a hallmark of 2025 is a resounding lack of empathy and compassion from people. Maybe's it's smartphones, social media, or some sort of existential doomerism. To reframe you…

In high school, I ran a robotics team that did lots of STEM outreach. We went to community centers, after school programs, and worked with other similar orgs like "girls who code."…

Gotta fetch images and stylesheets from the network!

Yeah not sure why someone's first reaction to seeing 150ms Rust hot-patches is to call it BS and a "pain-in-the-ass." Tough crowd. We could aim lower, or make it entirely automatic…

It’s a developer tool to speed up rust iteration, not a production tool like erlang. That being said, bevy is using bevy-reflect to implement proper struct hot-reloading between ho…

The challenge is that if the program is busy in a spin loop, there's no way to preempt it and modify it. Things like malloc, spin loops, network requests, syscalls etc. I looked in…

You basically need to wrap your program's `tick()` function. Otherwise you might be in the middle of malloc, hot-patch, and your struct's layout and alignment changes, and your pro…

There's a custom `axum::serve` equivalent we built that wraps the router construction in a hot-patchable function. When the patches are loaded, we reset the TCP connections. It's a…

Creator here - you only need one `subsecond::call` to hook into the runtime and it doesn't even need to be in your code - it can be inside a dependency. Currently Dioxus and Bevy h…
