@robpike definitely not missing my SCSI DAT backup that cost a fortune and never worked properly on Linux in 1995.

It's been a while since the last one, but here is the fourth #Landlock newsletter: https://lore.kernel.org/landlock/20240716.yui4Iezai8ae@digikod.net/
Moar sandboxing! 🥳

Another relatively small update, but here are the LSM, SELinux, and audit* highlights from the Linux v6.11 merge window.

There are three hard things in computer science: cache invalidation, naming things, and getting your video game character onto a ladder.

@gigabecquerel this is giving me anxiety

@ftg these are incredibly useful for all kinds of basic testing, and yep, that is the right coax to use, and yep, I forget what it's called too

Of course, everyone's favourite tool to build secure Linux images with dm-verity, TPM, SecureBoot is mkosi by @daandemeyer and others. It now is learning a new trick: support for AzureLinux (ex CBL Mariner) – in addition to the other 12 supported distributions.

And that's really great, because this means I can finally quickly test the stuff I am working on within the systemd project on my own company's Linux distribution, the same way I test other distributions.

Yay!

#Landlock workshop: Linux sandboxing in practice

Let's sandbox ImageMagick at #pts24 🧂

Imagine being a billionaire and not living in a house like this.

Narrator: you cannot trust an $8.99 7-port USB hub.

@g4dbn @M0YNG something that surprised me is people running FT8 at 700W on HF. Weak signal HF to me was always 5-10W.

Really “enjoyed” hand soldering this VSSOP device with 0.5mm pitch. Time to get a hot plate reflow setup.

Pioneering computer scientist, electrical engineer, and transgender activist Lynn Ann Conway has died at the age of 86. Every modern silicon chip incorporates her ideas, and her courage was an inspiration to many. https://en.wikipedia.org/wiki/Lynn_Conway Long may she run...

Zip disks, anyone else remember these existed? Anyone?

@th @janamarie such a great idea

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 ;)
