This event is really growing! Hoping it continues to remain a true grassroots event.

Finally learning to mill, in a work makerspace. This is a game changer for all kinds of projects. My first task is smoothing out a copper heat spreader, which was extruded and less than ideal for heat transfer.

I hope that everyone understands that my blog isn't all that interesting and that's kind of the point.

I'll say more about that later. But seriously, it's OK to slow down and just have fun with something. That's what I'm peddling here.

Finally bought what seems to be the bible on #radioastronomy - Kraus. I have several other books which seem to defer to Kraus on some of the “basics”. Good to have all of the essential information in one place. Seems this book is only currently available as ring bound or a cheap paperback. One specific goal I have here for 2024 is to properly understand wave polarisation & Stokes parameters.

@pid_eins I'm using the Akkoma web client which allows quoting, amazingly.

The video of the 2nd of my FOSDEM talks is online now. (The 1st one not yet) It's from the boot loader MC and about systemd-boot, systemd-stub, UKIs, and that stuff. I.e. hopefully providing some explanations on why we think distros should consider switching to these and away from their current boot loader choices.

It's a lot of information, packed in a short 20min time slot. Enjoy → https://mirrors.dotsrc.org/fosdem/2024/aw1126/fosdem-2024-1987-systemd-boot-systemd-stub-ukis.av1.webm

My 1st FOSDEM talk is now online, too. An exciting hour of me rambling about our TPM future, with a focus on what's in store for distributions:

Enjoy!

It's been a while since I looked into different #fediverse clients. Is there a good threaded web based client, or cross-platform app?

@kellylepo great story, which I'm assuming is getting very well known now

#electronics Pro Tip: do not apply -30V DC across the Vin+ and Vin- pins of INA169 current sensor chips. They don't like it.

Great high-side alternative to low-side digital current meters, fwiw:
