Carlos Bederian @zzzoom.bsky.social · 12/06/2025Me 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. 010

Carlos Bederian @zzzoom.bsky.social · 07/04/2025Used 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. 000
Carlos Bederian @zzzoom.bsky.social · 28/03/2025Thank 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. 100
Carlos Bederian @zzzoom.bsky.social · 20/03/2025That's a...25C jump in temperature to 344l of water per minute? 010
Carlos Bederian @zzzoom.bsky.social · 14/03/2025The processor market hasn't been this competitive in years, maybe ever. 100
Carlos Bederian @zzzoom.bsky.social · 13/03/2025I'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. 110
Carlos Bederian @zzzoom.bsky.social · 05/03/2025South American HPC leadership is in dire need of such a course. I'll float the idea to CARLA organizers. 040
Carlos Bederian @zzzoom.bsky.social · 14/02/2025"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." www.microsoft.com/en-us/resear...microsoft.com 010
Carlos Bederian @zzzoom.bsky.social · 12/02/2025Barely 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? 010

Carlos Bederian @zzzoom.bsky.social · 10/02/2025Borrow 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. 110
Carlos Bederian @zzzoom.bsky.social · 07/02/2025Before tensor units FPGAs could offer similar performance for some problems at much lower power. 010
Carlos Bederian @zzzoom.bsky.social · 06/02/2025"Today" kind of kills the cheap part of it, you need to take some risk for a bargain. 010
Carlos Bederian @zzzoom.bsky.social · 06/02/2025Zig 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. 110
Carlos Bederian @zzzoom.bsky.social · 06/02/2025I spent way too much time rewriting nice Julia code into not so nice code to avoid allocations in order to get decent performance. Also left a bad taste. 110
Carlos Bederian @zzzoom.bsky.social · 06/02/2025Is anyone doing #HPC with any of the new languages competing with C++? Rust seems to get in the way of playing fast and loose a lot. Zig seems to be an overall improvement but it probably doesn't bring enough to the table to justify switching. 592
Carlos Bederian @zzzoom.bsky.social · 04/02/2025It didn't take long for bluesky to become as depressing as Twitter. 020
Carlos Bederian @zzzoom.bsky.social · 31/01/2025Had to agree with the orange site on this one: Ghostty is a good terminal not because it's the fastest or has the most features but because it has sane defaults. Install, set your font and theme, set TERM in your ssh config, you're done. 000
Carlos Bederian @zzzoom.bsky.social · 28/01/2025Ackshually that's only the Ethernet part of the driver. 110
Carlos Bederian @zzzoom.bsky.social · 27/01/2025Spent a week working on an ancient piece of code with exponential runtime, only to figure out a solution in linear time in the shower. 🤦♂️ 000

Carlos Bederian @zzzoom.bsky.social · 13/12/2024P100s are cheaper and Titan V does much much better than that for less than $400. 100
Carlos Bederian @zzzoom.bsky.social · 05/12/2024Does the federal govt need to do anything? Most of the AI ecosystem right now is American. 000
Carlos Bederian @zzzoom.bsky.social · 30/11/2024dracut supports downloading live images via BitTorrent. EDF used to run ctorrent to download their HPC node images, maybe they still do. 010
Carlos Bederian @zzzoom.bsky.social · 28/11/2024They could also preempt lower priority jobs when needed. 000

Carlos Bederian @zzzoom.bsky.social · 18/11/2024Our triple de miga usually has 3 thinner layers of crustless bread, the minimum amount of ham and cheese, and some mayo/margarine/butter spread keeping it together. 130
