High Performance Computing/Scientific Computing, Linux system administration, amateur radio are my interests. Presbyterian elder interested in theology and science. IEEE CT Section Officer. Opinions my own.
Just wondering for those that follow me, do you use Google Gemini? I’m considering subscribing, but wondering what people use it for?

Happy New Year.

May 2025 bring us all: a large amount of love, enough hard work to make us proud, full-throated joy, the ability to grow.

And most of all, may it bring us the stamina to pause, or perchance to retreat for a bit, but never, ever to give up.

Happy New Year! Looking forward to another year of keeping HPC systems running and developing new strategies.

Chernobyl should be required viewing for SREa or anyone that deals with incidents in complex systems.

In the mid-90s, we had an amateur radio data repeater near me like this article mentions for TCP/IP. The system here in CT worked really well.

Voip.ms is a great provider if you want low-cost VOIP services, but it is very much DIY with all the settings. Getting Groundwire and other VOIP clients to work take a bit of adjusting to get SIP-TLS to work, as there are a bunch of advanced settings to configure in both places.

On Giving Tuesday made some donations and renewed USENIX membership. I noticed the ATC '25 meeting will be in Boston next year. Might be able to attend that one!

any experts on Bluesky know if I change my .bsky.social to a domain name, if I want to change the domain name in the future to another one or go back, does it mess up any links or references to the account?

Since I’m in industry, I haven’t used EDUroam. What is the advantage for academic users in signing into that network? Are you able to get back to your institution without using a VPN? Or if your device is already configured, you don’t have to sign in to the SC network? #hpc #sc24

Just finished volunteering at the SIGHPC booth. Always good to network with others and encourage students!

Looks like a good crowd at #SC24 today!

I’ve found that turning off bluetooth when in packed sessions on a MacBook may save on CPU / energy usage. Not sure how much battery savings it provides, but was surprised how much the bluetoothd process starts to work. #sc24

Heading out to #sc24 soon!

This was the first community I looked for when I got off X a year ago. Glad it’s coming together now!
OK, let's try this to show the HPC community already has momentum and can thrive here on Bluesky ...

If #HPC or #supercomputing is of interest to you, please interact with this post in some way - either repost, quote, like, reply with insights or just your fav gif, tag friends, etc.

It’s great to see many HPC practitioners here since I got off X last year!

80 degrees F in CT today! Nice day for a walk.

10meters seems to have been open most of the day today from the east to west coast. Lots of stations heard on VARAC. #hamradio

Another Supercomputing conference in the books! Great to reconnect with those in the industry in Denver!

Denver has such a nice view of the mountains. Got to get used to the thin air up here.

Surprising fact: no major professional scientific org has flipped from a paywalled publishing model to 100% Open Access.

The ACM, the world's foremost professional computing org, is going to be the first on January 1, 2026, when its entire digital library will become freely available to the public.

IEEE HPEC (High Performance Extreme Computing) conference is next week. IA free registration option is available. This conference started out as an in-person conference in the Boston area. Now it is completely virtual. The keynotes look very interesting!
