Would you trust an $8.99 7-port USB hub ? Asking for a fiend…

I think I have teased this already, so here it is:
Proudly presenting “ligra”, an open source projector/projection (LiGra – Light Graffiti) platform, allowing you to broadcast your messages, your logos, your artwork, whatever you need others to hear, to whoever sees it! :3

With ligra I wanted to explore image-projection and especially projections on the cheap, so I went to my local flea market and built a platform around old camera lenses. You can find two of them in the wild at #GPN22

A nice evening of trying to get the best out of our SEM!

@pid_eins @GabrielKerneis needs a Rust rewrite anyway ;)

@sundogplanets I don’t think it would be radioactive ?

I hope this toot finds you well

@pid_eins @GabrielKerneis is this fixable in libselinux, or is it too far gone?

@SteveSyfuhs unless that's what the virus-infected site wants us to think...

TIL: KiCad.

Incredible project, an open source MRI machine. Build video / workshop: https://www.youtube.com/watch?v=1q0dXg17E_w

Should I install this software?

@maehem that font brings back memories.

A gentleman named Paul Khoury approached me about getting a retro computer he'd acquired up and running. The computer is a Sun SPARCstation UPN (1997), a prototype for a super small desktop computer that preceded the Mac mini by about 6-7 years. Only about 20 were ever made. I was the designer on the project and had poured my soul into it, so I was proud to help him get it running. I dug out the schematics from storage and gave any advice I could remember and he got it powered on in a few days.

@BoscoLab I need one of these!

@g4dbn thanks. Getting some low band (3cm) projects done before heading back up to mm-wave+.

Very excited to have a paper published in DUBUS. I’ve been reading this journal for about a decade and never imagined when I started that I’d be published there. The journal is also translated into German (or English) by the editors, as it’s a dual language publication.

1️⃣5️⃣ Here's the 15th installment of posts highlighting key new features of the upcoming v256 release of systemd.

systemd integrates with many components of the OS. Due to this it links against various external libraries. Generic distributions – which typically enable all features a package provides – usually have to deal with relatively large dependency trees in cases like this.
