With Oxide, your compute gets more valuable over time, not less. The same Rack Model 0 we launched in 2023 now supports more than 2x the vCPUs per rack with our latest compute sleds and system version 21 which adds support for Zen 5c processors.
This week I received a Deimos DAQ Rev7 from @deimoscontrols.bsky.social It acquires precision measurement, here from two thermocouples, and can use these to control outputs, here a GPIO pin. All controllable from #Rust (or python). Thanks @ponderingpothos.bsky.social for all your help!
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!

"We have generic parameters from outer item at home" play.rust-lang.org?version=stab... I feel like I keep re-discovering that this works, and forgetting why it's more limited than I actually want it to be in the general case, but it does print what you'd expect it to print :)

i agree with conputer dipshit: looking at what's coming and not thinking it's going to raise the water line for shipped software is nuts
conputer dipshit@davidcrespo.bsky.social · 3mo agoI don’t really get the hopelessness here. the cost of avoiding at least some of these pathologies has just gone down by like 95%. the best open weights LLM knows 100 times as much about a11y as the typical dev and does not get bored

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...

Computational Cosmetologist@dferrer.bsky.social · 3mo agoI 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...
The parallels between the rise of CNC and AI are astonishing. We went from "this will de-skill machinists" to the modern marvels of engineering that we all take for granted, like the one I'm typing on. Another excellent video from @asianometry.bsky.social www.youtube.com/watch?v=OgXm...

Some fun compiler-adjacent #RustLang reading: How can you make sure [panic!] is unreachable in part of your program? This write-up goes into how we approached callgraph analysis in #Ferrocene – and how you can try it out for yourself! 👉 ferrous-systems.com/blog/callgra...
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
Cat Hicks@grimalkina.bsky.social · 6mo agoI 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
