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.

Lots of recent picolibc news:

* Oliver Stannard at ARM got testing running on the FVP emulator for more rigorous AARCH64 validation.

* Eduard Tanase fixed a bunch of documentation issues.

* Joel Holdsworth added OpenRisc support.

* Jiaxun Yang fixed my janky tools situation by creating picolibc-ci-tools which auto-builds all of the extra bits we need for CI. They also add LoongArch and LatticeMico32 support. The latter uncovered GCC bugs which I had fun fixing.

Thanks to all of you!

@paninid but nobody ever reads them, which seems problematic.

Dumb legal question: if people generally do not read terms of service type documents, how are they valid as a legal vehicle?

util-linux has merged support for statmount() and listmount() to list mounts:
https://github.com/util-linux/util-linux/pull/3092#event-15865684400

This should be a nice performance improvement.

See https://brauner.io/2024/12/16/list-all-mounts.html for some details on listmount() and statmount().

@HopelessDemigod @Athena 60 kHz, sounds like WWVB?

@Athena I sometimes scan HF CB channels when driving long distances out of boredom. Usually uninteresting.

Here's a brief blog on my amateur radio publications last year: https://w7txt.net/2024/12/29/publications-in-2024/

- Investigating the Extended Frequency Range of the WA1MBA Millimeter Wave Quadrupler.

- Open Source Arduino Controller for Surplus Flatpack2 PSU.

It's a gamma compensated neutron ionisation chamber!
Basically two chambers in one, sharing one electrode. One chamber is coated in boron to make it neutron sensitive, the other isn't and with some clever wiring of both chambers you can make sure the current on the shared electrode is just from neutrons, regardless of the gamma background!

You'll typically find these very close to a reactor core, used for measuring power.
