Best place to engage on technical topics with actual people:

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

Telegraph poles like these, with multiple "code lines", were once a common feature along American railroads. They are distinguishable from ordinary power or telephone lines by their multitude of cables, often occupying several crossarms. They typically carried a power bus plus individual lines for the signals along the route, with more efficient encodings used as technology improved.

They've been mostly supplanted by more modern SCADA systems that don't require so many individual wires.

@harld Ja, daar lijkt het sterk op.

@n8dmt I haven't tried modifying or making stuff at this level, yet. Could change soon.

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?

@MLE_online "is this... Dutch?"

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 :)

And then your's truly will give four talks, at various different places. First of all I have a keynote:

And unlike some well-known billionaire I am not going to chicken out of my mine. Ha!

@LaF0rge all this will be important for rebuilding society after the next war

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.
