Such a great team to work with.

And such a fun model to play with!

World models are moving beyond offline generation towards interactive, real-time experiences.

Introducing ⚡FlashDreams⚡: an open-source high-performance inference and serving library built for autoregressive world models:

🔥 Up to 3.10× faster LingBot-World inference
🔥 Up to 2.12× faster Self-Forcing inference
🔥 Up to 1.40× faster Wan2.1 inference
🔥 8 integrated models
🔥 Multi-GPU, streaming, low-latency serving
🔥 Agentic skills that teach you how to use it

FlashDreams is designed for a new generation of AI systems that continuously evolve over time while responding to user interactions. It powers applications across robotics, autonomous vehicle simulation, gaming, and virtual worlds.

I'm excited to share a Vulkan library/provider I've been working on. I'd love to hear what you think!

- Lightweight C++ RAII + utils
- Composable, to make things quick, not an ecosystem
- Just build and run, no Vulkan SDK needed

struct Buf {

~Buf() { glDeleteBuffers(1, &m); }
GLuint m;

Mesh obj(...) {
Buf indices(...);
Buf positions(...);
return {indices, positions};
}

Can u spot the #cpp bug? 👀

I wrote a proposal for memory safety in C++. It's in this month's WG21 mailing.

Ever wanted to quickly read/write files but found fstream/fopen combersome?

I made a thing: https://t.co/BSJJAwPpUR

- Write to a memory mapped file instead
- Write binary data, no serialization
- Pointers remain valid while writing
- Growable memory

I was idly contemplating making my own ergonomic mechanical keyboard back on 2022/07/11. I've just finished the left half and decided to start writing about the journey: https://t.co/xTu1FN8wvf

TIL std::filesystem::path joins using the "/" operator 🤣
Next we'll be using "." for the dot product.. 🙄

What Is My GPU Painting Today?

[Pyarelal Knowles @heuristic42]

Finally got some time to play with an #Arduino again 😃. The display just wouldn't work, until eventually I did absolutely nothing and it did... And people laugh at me for recompiling just to see if the error goes away by itself.

[Pyarelal Knowles @heuristic42]

@artwesha ooh. new ones. I like the colours

Got tired of waiting to select which OS to boot, so I made a physical switch

Go big or go home! The #MarsHelicopter successfully completed its 2nd flight, capturing this image with its black-and-white navigation camera. It also reached new milestones of a higher altitude, a longer hover and lateral flying.

[NASA @NASA]

🚁 On Mon., April 19, our Ingenuity #MarsHelicopter makes its first attempt at flight. Watch live coverage from @NASAJPL beginning at 6:15am ET (10:15am UTC) as the team receives the first data & finds out if they've made history: https://t.co/JFEsGuAYbr
