Especially once you start selfhosting anything large.

Using an NPU / APU to accelerate something small isn't a terrible tradeoff, as soon as you deploy some real accelerators you're burning so much energy. Can't disaggregate, won't be able to keep batches full, will have idle time ...

oh dear, you've imported some of the horrors of GPU shared memory/LDS swizzling to CPU land.

Your best hope is that in the future amdgcn-spirv target usage shows up widely and the spirv path happens to work for 803.

If not that, it's possible to try to build with 803 as your only supported target for the entire package set but I'd expect big trouble.

my shader export compression is mightily broken and the effect is eerily reminiscent of trying to make out details in a night sky obscured by light pollution, except the sky now has intermittent complex transforms darting across its surface

GeekWire excerpt: "In addition, while all Ai2 programs for 2026 are fully funded, these people said, FFST is moving from providing Ai2 with overall annual funding to a proposal-based process, with future support expected to favor real-world applications of AI over building open-source foundation models. The shift helps explain the departures of researchers focused on model development."

The words 'over building open-source foundation' are highlighted in green.

The OLMo fully open foundation models are probably not going to get new revisions.

Pretty sad as they were one of the few true open source options - mostly 'open weights' models don't share training recipes or data and are more like freeware.

define your own macro that also checks a crate feature to override to take the fallback path, run tests with and without that feature?

The implication that someone has to hate writing code to be happy to be able to automate some of it doesn't make much sense to me.

I got into programming as a child because I like making things run better or making new things, not because I intensely value typing in specific lines of code. No financial pressure, definitely for the love of the game.

Embed image for a lunnova.dev blog post about ROCm 7.1.1 (AMD's GPU compute stack), styled entirely as a Neon Genesis Evangelion title card homage. The bold, squashed, serif typography, the red-and-white-on-black color scheme, the embossed red "m" in "ROCm" (mirroring the iconic red "N" in EVANGELION), and the tagline "You can (not) build." with "(not)" in contrasting replicate the Evangelion titling aesthetic.
The background shows htop CPU %age bars in a state of overload and distress, fading towards the bottom of the screen.
The date (left) and lunnova.dev (right) are displayed at the base of the image.
