@ftg looks like indium shim ?

It feels like cheating to use these pre-cut wire links for soldering (vs. push-in breadboard), but I’m over making these by hand. #amateurradio #hamradio #electronics

@kelvin0mql @vees you need to visit the Australian outback, Milky Way easily visible (much better vantage point) and you can also see the Magellanic Clouds, with the naked eye.

@jarkko I’ve never played with FPGAs, need to fix that at some point. This is possibly very relevant to RF digital, lots of amateurs now using s/w modems via usb sound, but performance is not optimal at high bandwidths. They will struggle to utilise the full potential of the recent FCC changes in the US to increase the data rates allowed on HF.

Prototyping a monitor circuit for GaN RF power amplifier devices. This is indicating drain current and heat sink temperature, and can be expanded to other measurements as needed. What started as a ‘simple’ project became an entire side quest. This uses an Arduino Pro Mini, an INA169 current sensor, and a thermistor. Could be done more simply with a PIC but this is what I had. The cheap OLED display self destructed not long after this photo, as I fed it 12v instead of Vcc.

@bytex64 post some?

📣 Postdoc job alert 📣

The “Astrophysical and Cosmological Relativity” department at the @mpi_grav in Potsdam announces the opening of several postdoctoral appointments.

These appointments will be in the area of data analysis and its interface with waveform modeling for the recently adopted space-based gravitational-wave detector LISA.

[$] Systemd heads for a big round-number release https://lwn.net/Articles/971866/ #LWN

@lzg many protestors have absolutely no idea what is going on or who they're working for

Uh, why does dropbox "need" access to my contacts?

Linux Plumbers 2024 has accepted 9 Microconferences! But we had 26 submissions for 18 slots! What to do with that? Read about it here: https://lpc.events/blog/current/index.php/2024/05/03/awesome-amount-of-microconference-submissions/

Got slightly distracted in midjourney.

This is Seattle, Cascadia in 3357, on the 1000th anniversary of The Fault.

Idaho's Mount Mersini-Houghton is in the background. Also notable is the newly refurbished Space Needle Memorial.

@g4dbn nice, I was thinking about the Edmunds dishes for mmwave. Are you planning to make more of these for sale?

@gigabecquerel did you order them cut like that?

2️⃣ Here's the 2nd installment of my series of posts highlighting key new features of the upcoming v256 release of systemd.

This time we'll talk about encrypted credentials. Credentials are these little pieces of information that you can pass into systemd systems and into system services. They can carry secrets but also other kinds of parameters. One key feature is that they can be encrypted while at rest, locked against the system's TPM…

6️⃣ Here's the 6th installment of my series of posts highlighting key new features of the upcoming v256 release of systemd.

In the 2nd installment of this series we have already discussed system and service credentials in systemd a bit. Quick recap: these are smallish blobs of data that can be passed into a service in a secure way, to parameterize, configure it, and in particular to pass secrets to it (passwords, PINs, private keys, …).

Reminder that the CFP for @allsystemsgo 2024 is open, one month and two weeks to go until the deadline! You can submit your proposal at https://cfp.all-systems-go.io/all-systems-go-2024/cfp
Tickets are also on sale at https://all-systems-go.io/
