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

@HopelessDemigod nice.

@mcfadden Solid recs to help lift that SAD!

@petrillic Yikes, that seems to be very simple. Video: https://media.ccc.de/v/38c3-hacking-the-rp2350

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.

I've written a post that shows how to list all mounts in all mount namespaces (all mounts on the system) using new apis we added to the #vfs last year.

Here's a blog story with the links to all those #systemd257 stories on Mastodon:

Enjoy! And stay tuned for #systemd258!

I'm also on bsky: https://bsky.app/profile/jamesmorris.bsky.social

Seems to be growing for #amateurradio & related lately. Currently I'm randomly posting across X, here, and bsky.

What is the secret to getting tigervnc-server working under Fedora 40?

@LaF0rge @c3gsm @c3isdn @ChaosPost @fixeria @manawyrm @qsx you would have loved the days of x.25 in Australia

@va3db this is THE WORST part of any project. A jeweler's saw can be useful, if you haven't tried it yet. One day I'll have a small milling machine for this.

1️⃣9️⃣ Here's the 19th post highlighting key new features of the upcoming v257 release of systemd. #systemd257

A relatively basic feature of systemd's service management is the ability to automatically restart a service in case it terminates unexpectedly, configurable via the Restart= setting.

In v254 we added the RestartMode= setting that allows to fine tune the mechanism to use for restarting the service, i.e. it adds a logic to optionally avoid marking the service as failed between…

@LaF0rge @qsx @ChaosPost @c3isdn @c3gsm @manawyrm @fixeria do you ever play with old teletype machines? They are fun, you can connect them to each other with TP and send messages over quite amazing distances.

@spacetelescope definitely worth clicking through: the image holds a second discovery that’s easier to overlook. Examine the white elliptical galaxy at left. A faint red arc appears in the inset at 10 o’clock. This is a very distant galaxy whose light is bent by the gravity of the elliptical foreground galaxy – and its appearance is duplicated. The stretched red arc is warped where it reappears – as a dot – at 4 o’clock. These images of the lensed galaxy are so faint and so red that they went unrecognized in Hubble data, but are unmistakable in Webb’s near-infrared image.

I've been seeing slow downloads from #Fedora mirrors yesterday & today, pretty sure my Internet connection is ok. Anyone else seeing this?

@mossmann thanks, this will be simpler than growing an extra arm.

@mossmann where can you buy these?
