Tenstorrent decided to publish the first benchmark data for Ascalon's RVV implementation using the instruction throughput benchmark of my rvv-bench benchmark suite. <3

Overall, the results look really good so far:

Gemini data point is likely affected by the fact that Google includes it “for free”, so companies already using Workspace is likely to enable/allow it.

I guess LF has now dropped “Open” as well. Source Summit?!?

Oh, and that makes it 4 years of @tailscale.com swag. Stickers aged out with laptop upgrades since then, but the bottle is still in use.

It’s amazing how quickly you can forget just how painful classic VPNs are once you’ve switched to Tailscale, 5 yers have passed quickly.

There’s no going back.

They need him to be a genius because they cannot handle what it means for them to be tricked by a fool.

“Messiest urinal ever” goes the joke about the Dyson blade dryers, but this other brand named theirs Urimat. It seems a bit too close in the name space to me.

Problemet med X är ju överlag kvaliteten på inlägg och diskussioner numera. Det är ju mest en massa orelaterade svar och videor och spam.

Själva CN-biten verkar fungera bra när någon far med osanning.

Advent of Code 2024

Ah, December, with the joy of adventofcode.com.

Nightly little puzzles to solve, until I fall behind and miss a few and then lose track of them. Still, fun while it's going.

At Tenstorrent we are making progress on upstream support for our #riscv Ascalon core. We've got support in LLVM now and support for qemu is on the way.

It’s all fun and games until Oracle decides to sue anyone shipping <netinet/ip6.h>.

The year after that they introduce per-process IPv6 licensing for enterprise.

“So, there’s IPv6, which is deprecated. And there’s IPv7, which is not ready yet.”

Yep, sounds on brand even without pulling the KBG aspect.

Some libraries also have museum passes that you can check out!

Got to indulge in some old and not so old HW on display today! Missed taking a proper photo of the Cray C90. :(

Seems like CLEAR is the new TSA Pre. :(

It also seems that they just don’t have enough lines open, usually only one of the pre check scanners are manned.
