Is it just me, or does the whole world of DIN rail mount accessories seem woefully underdeveloped?

I think we've received our first easily identifiable AI-authored /AI-assisted job application. It looks suspiciously like the text from the job announcement, just rearranged.

I'm beginning to get quite a bit upset that there are no US-based manufacturers of single board computers on the small scale for industrial automation and lightweight #SBC #HPC demo and training cluster building. Having started with Raspberry Pi and migrated to other processor choices, even the ones with #Intel chips are not turned into SBCs here, but by others overseas. This seems a huge hole in the Chips and Science Act for a domestic industry that's critical to IoT and automation in general.

If I could teach or coach just one skill for people, it would be debugging. Not just for computer problems, but analysis and root cause tracing and troubleshooting in general - how to think about and to anticipate problems, to figure out not just after the fact but also ahead of time what is likely to cause or be a contributing factor to problems.This is the skill that has brought me to where I am in life, which I think is a good place to be, and is something that I think could help others.

May add more cpu nodes (these are quad-core N100's), may add instead some GPUs. Haven't decided yet. Total investment so far in this 10-inch rack setup, 2.5 GbE switch, nodes, head node, power equipment and cables is less than 15% of what we typically spend on just one worker node in our main cluster.

In progress— parts for 16 nodes plus a head node so far. Intended target: a classroom cluster. Stay tuned! #sbc #hpc #cluster #education

2025 starting out looking like the opening scene from a GhostBusters film. I’m not sure this is a good sign.

Woohoo! Decisions have been made on the @fosdem '25 HPC, Big Data & Data Science DevRoom talks and the schedule is beginning to populate at https://fosdem.org/2025/schedule/track/hpc/ for what will eventually be a full day of very high-quality talks in Brussels Sunday 2 February 2025 with recording and streaming available. Thanks to Kenneth Hoste (@boegel) for his excellent organization of this 10th year of this DevRoom, a true service to the community!

My personal opinion (not backed up by anything more than logic and the base information) is that those who use referrer headers to identify sources of visits to their blogs etc. have missed the point that Mastodon doesn't by default include such headers, hence their attempts to measure engagement by platform were based on wrong assumptions. I know of several prominent posters of otherwise useful stuff on various platforms who have done such comparisons and made this exact mistake. (Again, YMMV.)

Hmm. The buzz was that there would be much more interactivity on Bsky than on Mastodon. Having been there a couple of weeks with a good list of followed accounts and followers, I'm not seeing it. There is more in the way of "broadcast" posts and news re-posts, and more organizations, but the personal interaction level seems quite similar to here. (YMMV.)

"Linus does raise a valid point on the linearization of the feature levels as Intel is currently stuck in an odd position given that their newer laptop/desktop CPUs do not support AVX-512 and then with AVX10 there is both 256-bit and 512-bit options, among other complexities in the handling."

We still have some hpc.social stickers to give away today at the Texas Tech booth, along with some other goodies.

Okay, you folks have convinced me to add BlueSky, though this account on Mastodon is still active and preferred for me: https://bsky.app/profile/alansill.bsky.social

Update: Thanks to a timely loan from Purdue we will have the display monitors working at least for the opening ceremony, and the full booth materials will arrive tomorrow morning. Thanks to everyone who responded to this on various channels, and please feel free to stop by booth 814 for some chocolate and an hpc.social sticker!

The answer to supporting older X11 applications in Wayland-only environments seems to be Xwayland, as explained at https://wayland.freedesktop.org/docs/html/ch05.html for example. Does anyone have any experience with this in an all-Wayland cluster or server environment? There is more discussion for example at https://discussion.fedoraproject.org/t/switch-to-wayland-tips-and-tricks/107993/7 that seems useful, and other distros have similar pages in their forums, but no comprehensive guide. I'm mystified as to what we are supposed to advise remote cluster users when this hits.

If anyone in our #HPC circle of friends at #SC24 can spare a few items to help us out with a missed shipment, we'd appreciate a short-term loan of the following materials for at least a few days until we can get our shipment there:
Again, look for a spare-looking metal frame with some forlorn Texas Tech people at booth 814.

Well, rats. Just found out from our Texas Tech team at #SC24 that several of our small crates of needed material never made it into the larger ones to be shipped.
Look for a very spare-looking metal-framed Texas Tech booth no.814 at the exhibition. We will still have chocolate, a couple hundred hpc.social stickers, and various other small items to give out, and you can talk to our staff members and students there, who (unlike me, who should have double-checked on the shipping) are very smart.

So RHEL10 (beta) follows through on the plan to drop X11 in favor of Wayland. Despite the pain this will cause older X11 applications (those who made this plan have no idea how long academic and scientific users hang on to old applications!), I support this, but it leaves many problems unsolved. Among these, unless I'm missing something, is support for remote display in other OS's besides Linux (for example, XQuartz on MacOS or MobaXterm for Windows). Does anyone have a good summary or pointers?
