Does anyone actually replace their whole hard disk fleet every 4 years?

Your voting system isn't that resilient to shenanigans.

Concurrency problems are hard to reason about, users are usually shielded from them.

Me sorprende que no lo haga WhatsApp también, que por suerte es la única basura de Meta que tengo instalada.
Igual también uso Brave que bloquea el pixel.

Twitter is that way ->

a man in a suit is walking down a sidewalk . Alt: Verbal Kint stops limping and starts walking as Keyser Soze

So now we'll finally see the clues that were there all along, right?

It just works

The inaugural High Performance Software Foundation Conference offered updates from HPSF projects, insights on processor & system trends, active discussions around the future of interoperability, and more. ▶️ Find our #HPSFCon recap and links to all the recordings at: hpsf.io/blog/2025/hp...

Are recordings going to be available online?

Used to? If Linux on my desktop wakes up at all it's to a completely broken dual monitor setup. And distros won't even touch hibernating with secure boot.

Thank you for these recaps.

Looking at Blackwell and not seeing the slightest mention of a single server solution, let alone a standalone GPU, paints a sad picture for constrained budgets. Makes me feel stupid in retrospective about asking AMD people for a PCIe MI300.

But so many tokens!

That's a...25C jump in temperature to 344l of water per minute?

The processor market hasn't been this competitive in years, maybe ever.

I'm running Ryzen Master to measure which cores can be undervolted less than 0.03V in 0.001V steps.
Puts the old days in perspective where you could buy a Mendocino Celeron or Thoroughbred Athlon XP, slap a decent heatsink on top and just bump its frequency by 50% for free.

South American HPC leadership is in dire need of such a course. I'll float the idea to CARLA organizers.

"Moreover, while GenAI can improve worker efficiency, it can inhibit critical engagement with work and can potentially lead to long-term overreliance on the tool and diminished skill for independent problem-solving."

Barely getting 25MBps reads out of old data on a WD SATA SSD. One would expect the controller to refresh cells every once in a while...right?

@hpcguru.bsky.social new head of Intel DCAI?!?!11!?

Borrow checker and having to either handle or unwrap *everything* for starters. I know that's advocating for bad practices, but it feels oppressive when prototyping.

Before tensor units FPGAs could offer similar performance for some problems at much lower power.

That used to be the FPGA pitch

"Today" kind of kills the cheap part of it, you need to take some risk for a bargain.

Zig covers that niche, and it has comptime for metaprogramming which makes more sense than C++ TMP or slowly constexpr-ing everything in the language and standard library.

Pkg is great though.
