the debugging manifesto poster I've been talking about is finally available for sale! You can get it here for $20 US + shipping: https://store.wizardzines.com/products/poster-debugging-manifesto

it was redesigned and riso printed by Inner Loop Press and I'm SO delighted with how it turned out (https://www.innerloop.press/)

Shameless begpost:

Since a couple people have offered, I wonder if I might not be out of line to try my luck openly.

So here’s the story. I’m poor. What money I earn generally goes back into making stuff. That’s fine. It makes me happy and keeps me busy. But it does mean that I face certain challenges, specifically with the cost of test equipment, which is pure capitalist insanity.

My multimeter is absolute dreck. My oscilloscope is of very limited use being an El Cheapo model. I need better gear, and can’t afford it. I have been getting a lot of mileage out of crap gear, but there is a limit to what can be done.

So if you have test equipment gathering dust, like a bench meter, oscilloscope, logic probe, bench power supply, that sort of thing, I would be very happy and grateful to adopt it. Your basic test equipment you’d expect to use if you were designing a computer from scratch. I don’t need fancy, but nearly anything is better than what I have. Don’t deprive yourself on my account though - I’m soliciting specifically stuff that is going unused.

And if not, no worries.

Just published the #ASG2024 schedule! Lots of good stuff, and at least one terrible talk that nobody should attend.

Early bird tickets are also still available - but not for long - go grab them while they last!

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.

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 🧂

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...

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!
