We haven’t found evidence of Stingrays being used at protests in the US yet, but if you’re going to a No Kings protest this weekend, why not bring Rayhunter to be sure? Don’t forget to charge and update it, then let us know what you find! https://efforg.github.io/rayhunter/support-feedback-community.html

New C compiler dropped:

Looks interesting. GPLv3 for the compiler itself. Some optimizations; have not looked into them yet. only x86_64 backend so far.

X is where you find the people who think they run the Internet.

Bluesky is where you find the people who think they ought to run the Internet.

Mastodon is where you find the people who actually do run the Internet, and kind of wish they didn't.

Well, I just got laid off from my job. If anyone needs a talented embedded systems engineer or hardware engineer with strong experience in video hardware, send me a message with details of a job opening and I can provide a CV. Remote work preferred, but I can work anywhere in central Minnesota. Boosts welcome and encouraged.

My first die shots. You can see a lot more than I'd imagined without a microscope. This is a 1:1 macro lens, and just changing the angle/size of the light source gives you a ton of control.
