Nice. Very nice. @almalinux

"Oh, you're a fan of π day? What are the first hundred digits?"

Ok, I'm close to giving up on running my own mail server. Spammers are winning the arms race vs. small mail servers.

What commercial services are folk using for personal mail domains?

The results are in, with 18 votes. I kind of like bsky but not seeing a critical mass of people in my areas of interest.

If you answered other, please feel free to explain.

In honor of this landslide vote, here's a photo of my latest tinkering: making pipecap filters for an 11 GHz RF multiplier (using the W1GHZ board & design). I'll use brass M3 tuning screws once some arrive from McMaster-Carr, although I'd be interested to see if they are very different to stainless steel. And yes, I had to order them online after not finding any metric brass fasteners locally. Why not use SAE screws? Standard metric screws have much higher TPI, even more than fine-thread SAE. This will provide better mechanical stability & finer tuning, but then again, I'm not building a spaceship here, so 🤷

Best place to engage on technical topics with actual people:

Well folks, I'm on vacation again, and you know I could not resist...

Weekend tinkering: finally made enough room for a microscope on my bench and looked at small things. The chip of interest is 0.7mm wide: a ~60 GHz amplifier.

"We’re writing to inform you that we intend to discontinue sending expiration notification emails. " https://letsencrypt.org/2025/01/22/ending-expiration-emails/

Understandable, but I'm guessing this will cause a lot of breakage for a while & train people to click through browser security warnings. Thoughts?

From an ebay listing. It's real.

Given the increasingly toxic environment in the US and elsewhere, I'd like to express my support for all transgender & intersex people. Sorry you're dealing with this.

A quick summary of the LSM, SELinux, and audit changes merged during the first part of the Linux v6.14 merge window.

I'd like to announce two new libseccomp releases today: libseccomp v2.5.6 which is a minor maintenance release to the v2.5.z release stream, and libseccomp v2.6.0 which is a new feature release for libseccomp. More details in the link below, but libseccomp v2.6.0 adds support for new architectures, transactional filter updates, and more. Give it a try, you'll like it :)

Who says that pair programming can't be productive?

A giant Soviet telescope looks like a remnant of an older and more advanced civilization.

Its history matches this impression. The Kalyazin RT-64 radio telescope was developed to support communications with robotic missions to Venus and Mars and to prepare for possible manned expeditions to these planets.

The telescope is located near the city of Kalyazin, and still in operation today. Its scientific tasks include deep space communications and astrophysical research.

For the 2 weeks over Christmas + New Year, my work days were meeting-free. I got a lot of stuff done as a result. It was very freeing.

When I returned to a normal schedule this week, a sense of dread accompanied it. I considered why. It was meetings. Specifically, weekly obligatory pro forma have-em-because-they-are-on-the-calendar meetings. No-agenda meetings. The kind often organized by physics collaborations.

My resolutions for 2025: no agenda, no attenda. Only meetings with purpose.
