I just enabled ASTC on Tegra with, effectively, one line of code and got it right on the first try.
Do you have any idea how amazing this is?
You know. ASTC. The one format that has a non-power-of-two block size. The only format group NVIDIA supports where the block size isn't square.
First try. Every single Vulkan CTS test for ASTC passes.
On Intel, getting ASTC working was utter hell. We had so many image layout bugs. Block sizes of 4 were assumed all over everywhere. There were x/y mixups that only mattered for non-square blocks. The whole cooncept of a non-power-of-two didn't exist. Our block compressed format handling was also just plumb wrong.
Then Lina and I wrote ISL and put a lot of time and thought into how we do layout calculations to avoid a lot of the anti-patterns in the old code. Everything has units. Everything is an
isl_extent4dand those have helpers so you aren't banging on them manually. We carefully ensured that the calculation flow only went one direction and we never multiplied and then divided it back out later. ISL fixed so many bugs.With NVK, I wrote NIL which was based on our learnings from ISL. After Daniel helped me port NIL to Rust, I took it a step further and encoded the units in Rust types instead of just suffixes on variable names. This means you have to go out of your way to ever screw up a unit conversion.
The result is ASTC in one line of code.

hey me, hope you're doing well. out there in the future.
i've been coding in react a lot lately. i think the unified data flow really makes sense in wrangling in this frontend complexity.
i'm a little sad by all the build tooling though. It feels more complicated to scaffold a basic UI now than it was ten years ago. I'm sure ten years from now we'll have some sort of reactivity system without all the complex overhead.
right? right?

Una botnet ha distrutto accidentalmente I2P (la storia completa)
Il 3 febbraio 2026, la rete anonima I2P è stata inondata da 700.000 nodi ostili in quello che è diventato uno degli attacchi Sybil più devastanti che una rete anonima abbia mai subito. La rete normalmente opera con 15.000-20.000 dispositivi attivi. Gli aggressori l'hanno sopraffatta con un rapporto di 39 a 1. Ecco cos'è successo

A letter from 2016 to 2026 https://dustycloud.org/blog/a-letter-from-2016-to-2026/
Just imagine if you wrote a letter to yourself a decade ago! The tech world is full of possibility! AI is starting to make waves, but don't worry, we'll have minimum basic income! And more!

Taalas ha rilasciato un chip ASIC che esegue Llama 3.1 8B a 17.000 token al secondo
Taalas ha praticamente inciso i 32 strati di Llama 3.1 in sequenza su un chip: i pesi del modello sono transistor fisici incisi nel silicio.
Dovrebbe essere 10 volte più economico in termini di costi di gestione rispetto ai sistemi di inferenza basati su GPU e 10 volte meno energivoro. Non ci sono DRAM/HBM esterne, ma una piccola quantità di SRAM on-chip.
