Pro-tip: assume every Micro-B USB cable is a power-only cable until proven otherwise. I was sure I bricked my Airspy R2 SDR receiver, swapping in multiple different cables, different laptops, operating systems etc. Turns out every cable I picked up was for power only, even though I "knew" they were all data cables.

tl;dr: #USB

Interesting #fosdem lightning talk - https://fosdem.org/2023/schedule/event/gitlab_forge_for_teachers_and_students_in_france/

A gitlab forge for all teachers & students in France, supported by the Govt. I can't imagine what it would take to see something like this in Australia.

This is the Xgecu T48 universal programmer, arrived with a Lunar New Year gift. The T48 supports over 32000 chips, including a bunch that of older MCUs such as the PIC16C*

Can we embed videos here? Here's some nice #winlink activity, getting 3230 bps on 30m, over a distance of 400km. The 2750 Hz bandwidth is nice if your rig supports it!

Are you someone who has a simple fix for something in the Linux kernel, but haven't bothered submitting a patch because you find the email workflow daunting? Can be a bugfix, spelling correction, anything at all.

If so, I want to talk to you! I have tools that simplify this process quite a bit, but I need more feedback from people who aren't long-term Linux maintainers.

Please reach out, either via here or by emailing mricon@kernel.org.

A couple of pages from Alan Turing’s 1940 treatise on the Enigma machine. Is there a important piece of reverse engineering?

Pro-Tip for #pleroma instance users (like social.kernel.org), try the web frontend client! Accessible at fe.soapbox.pub or set your own up.

It's clean and familiar for Twitter users. You'll want to set dark mode unless you have eyes made out of kryptonite.
