The first official episode of @nicoleackermans.com and my show, @technicaltea.show just dropped on your podcatcher of choice + YouTube. Please enjoy moments like this where we hope to bring you women perspectives, STEM insights, and whatever you want to file "vibranium boobs" under.
Technical Tea@technicaltea.show · 2d agoThis is the kind of cocktail of women perspectives, STEM, and nerdiness you can expect from Technical Tea. And we are so proud of it. youtube.com/shorts/1sXRm...

I published vibrance-0.1.0 on Maven, now with support for Compose for Desktop (JVM). The APIs let you mix colors yourself, or draw gradients as modifiers or Compose brushes. Next steps: refine the model training to improve some color transitions, better alpha support. github.com/romainguy/vi...
In case you missed the phenomenal @mdevcamp.bsky.social conference, here is a link to the talk I gave there. I had such a great time there, and thank all the organizers for making it happen 🙏 🙏 slideslive.com/39082850/ele...
How was one of the most loved programming languages - Kotlin - created, and what is next after it? This is a rare and special conversation with Kotlin creator Andrey Breslav, with so many fascinating details on how Kotlin became the global success as it is today. youtu.be/ZggUn2mNqMU (cont'd)
I just added Brush APIs to Vibrance. You can now use pigments mixing based gradients with any Compose API that accepts a Brush. See README.md for code examples. github.com/romainguy/vi...
What To Learn To Be A Real Time graphics Programmer blog.demofox.org/2026/07/01/w... I wrote this up over lunch and it's surprisingly popular so sharing over here too.
A dream was always to make a "cloud" tool. Now over the last 1-2 years I tried to build smth on and off. Now I made it work in the browser. WARNING! Depending on the settings it can take a lot of GPU power, so be careful. Only for people who know what they're doing. artbuddy.urlich.ch/cloudbox/
I've been working on a Kotlin/Compose Multiplatform to interpolate sRGB colors as mixtures of paints/pigments. It can produce results that are more appealing than the traditional sRGB interpolation that Composes uses (see screenshot). Not quite ready for release yet. github.com/romainguy/vi...
Gobliiins Collection is AVAILABLE NOW digitally! 📢 Revealed moments ago during the AG French Direct, we are ecstatic to announce that the legendary puzzle-adventure series is making its console debut TODAY 👇 Play digitally or pre-order your PS5 physical copy https://bit.ly/m/GobliiinsCollectionRAG
Very interesting. Has SIMD support too. And shaders.
Mattias Ljungström@spacesofplay.com · 3mo agoI'm soft-launching my compiler project minc today. It compiles directly to minimal native executables for x64 Windows (PE), x64/ARM64 Linux (ELF), ARM64 macOS (Mach-O), ARM64 iOS, ARM64 Android (.so), and WASM. See minc.dev
Android is now Compose-first: developer.android.com/develop/ui/c... It was years in the making, and I'm happy to see it's finally here!

Android is Compose-first, and the Views system is now in maintenance mode, meaning it will only receive updates for highly critical fixes.

Naty Hoffman just wrapped up a career-spanning keynote on lessons learned from game development and beyond. Now underway: a fireside chat with Naty Hoffman and Eric Haines, joined by Omer Shapira - celebrating two remarkable careers in computer graphics. #I3D2026
This is a great example of why even small optimizations can matter at scale. Modern apps and systems can be affected by this kind of "death by a thousand cuts".

Hello Bluesky! I'm a Computer Graphics researcher at Inria Nancy. I work on physically based rendering & material appearance, and on computational fabrication / additive manufacturing - from glints and anisotropic BRDFs to non-planar FFF toolpaths. xavierchermain.github.io/publications...
Modern DRAM is based on a brilliant design from IBM. But, we're still paying for a latency penalty that's existed since the 60s! In this video, I'm introducing my research project (Tailslayer) that immensely reduces p99.99 latency on traditional RAM!
meshoptimizer 1.1 is out! github.com/zeux/meshopt... Featuring two new major features, meshlet topology compression and opacity micromaps, as well as a few smaller features and improvements! More information in the infographic and release above :) Boosts and repository stars are welcome!
It is sadly true - androidx ktx libraries have been killed today and it is all Jake Wharton's doing. Details here: jakewharton.com/an-update-on... #androidx #androiddev

My erosion filter is out! Video, blog post, and shader source. It emulates erosion without simulation, so it's fast, GPU friendly, and trivial to generate in chunks. Explainer video: www.youtube.com/watch?v=r4V2... Companion blog post: blog.runevision.com/2026/03/fast... #ProcGen #vfx #GameDev

Here is a preview of the results for my next post in the series on micro-shadowing. Hopefully people that value craftsmanship, deliberate art direction, and attention to detail will find it more interesting than the AI slop being pushed.
