New blog post for the WebGPU aficionados! WGSL layout rules are annoying, and I got tired of mismatched CPU/GPU layouts (because the failure mode usually required rebooting my entire laptop) As it turns out, it's not too hard to automatically cross-check them, with the power of runtime reflection!

Testing WebGPU data layouts with Facet

Using Facet's run-time reflection to check the layout of structs against their definitions in WebGPU shaders

I have been watching the dialogue on this one closely. To everyone who is saying "OP is special, no one could use AI this way" well, I have spent 18 months doing significant amounts of scicomm in patient communities and they are ALL using AI this way. wrote this to help: github.com/DrCatHicks/i...

I had strong priors against LLMs for medicine. There are a lot of doctors in my family and I grew up viewing doctors as careful, skilled professionals. I had plenty of bad medical experiences, but I thought it would be hard to do better. Then an LLM found a cure for my 2 decade chronic condition...

C++ programmers really will say 'you use borrow checkers? that pales in effectiveness to my strategy, properly de/allocating memory' and then not properly de/allocate memory

I'm almost there it's so pretty!! 😭 this is the first time I've made extensive use of complex numbers in shader code, which has been fun! it's an analytic 2D lighting system through piecewise conformal maps representing angular light/"sky" exposure, which means you get fully analytic penumbras!

Cat points out a real problem. Rather than “everyone builds their own custom app” with all the overhead that entails, my working hypothesis is that we’ll see an explosion of what @inkandswitch.com calls malleable software www.inkandswitch.com/essay/mallea... A solid core + ability to extend

Graph showing that there is a long tail of user needs and most apps tend to serve only the needs that most users have. The long tail is under-served

I think this gap is EXTREMELY real in a business sense and yet there is also the revealed other thing here which is a great deal of people in the world will never be remotely of interest to SaaS, and we know it, and those people still have needs suited to software

I whipped up another learning related Skill! Smaller than Learning Opportunities, but very complementary: interactive guidance through a quick research-backed psychological intervention that helps improve learning plans, motivation and commitment

Key to efficient learning is realizing how we ACTUALLY learn, not just what FEELS like learning. I wrote a Claude Skill for some friends to help them think about this and they've liked it -- see Principles for some directions you could explore github.com/DrCatHicks/l...

Outer Wilds, if you haven't played it yet, is one of the best games of all time. It's a fun space exploration game with a timeloop twist, and 90% of all game progress happens in your head, as you learn things about the universe and your situation. Absolutely play it if you haven't yet.
