Radical Pie has entered beta testing! I expect the final release to be available by the end of October.

TIL of VD-Dev, despite sharing past franchise titles with Guillaume Dubail and the late Fernando Velez. These guys were proper savants of their time, unlike those that tend to hit popular culture. I'm in complete awe of their work, Asterix & Obelix was mind-blowing.

The demo I’ve been working on is finally online:

ludicon.com/sparkjs/gltf-demo/

It demonstrates the benefits of real-time texture compression in 3D web apps. It allows you to compare models using traditional KTX2 textures (UASTC and ETC1S) with the same assets compressed as AVIF + Spark.

Remembering MN house speaker Melissa Hortman, her husband Mark and their beloved dog Gilbert. Murdered in June at their home by a rightwing Trump-voting evangelist, who also shot another MN lawmaker and his wife at THEIR home, 9 and 8 times, respectively (miraculously, they survived).

Writeup by @icastano.bsky.social — very worthwhile comparisons for anyone building texture-heavy applications in WebGPU, with a case study and integration in @threejs.org!

I am boycotting #SIGGRAPHAsia 2026 because it will be in Malaysia, where there are serious safety concerns for the LGBTQ+ members of our community, thereby excluding them. I will not attend, submit my work to, or perform any reviews for SIGGRAPH Asia 2026.

Yet, I'm excited about #SIGGRAPHAsia 2025!

There’s no problem in mountaineering that could not be solved by waking up earlier. My mistake was not checking the weather so I planned for a leisure start at 6am.

Dragon Peak, above the golden trout lakes. It’s accessed through the Onion Valley trailhead beet known for the Kearsarge pass trailhead. Dragon is just north of Gould and if I had been able to continue I would have traversed the ridge to Gould and dropped down to Kearsarge to return on a nicer trail

I think there’s some truth to that. Growing up in Sevilla I didn’t have air conditioning. It was considered a luxury. When we got one installed we didn’t use it very often, because energy prices were much higher.

Very big announcement from @icastano.bsky.social for WebGPU apps! Spark.js means you can send small file formats over the network (WebP, AVIF, ...) and compress to GPU texture formats like ETC2, BCn, or ASTC near-instantly using WebGPU — at runtime.

And finally, I’m thrilled to welcome Infinite Flight and Netflix as new Spark licensees, and deeply grateful to HypeHype for their continued support.

Spark 1.3 also brings new codecs, quality improvements, and even more performance optimizations. For more details, see our blog post:

And you can evaluate the codecs directly in a WebGPU-enabled browser:

I am excited to bring the Spark codecs to the web and can’t wait to see what you build with it!

spark.js wraps a subset of these codecs with a simple and lightweight API. Making it easy to use modern image formats for storage and delivery and transcode them at runtime to more efficient GPU formats. This is literally free bandwidth!

The highlight of this release is full WebGPU support. Spark’s real-time codecs are now available as WGSL compute shaders that run natively in modern browsers.
