Have you released your reverse engineered endoscope camera work? It's something I've been thinking about doing myself, since the vendor apps leave a lot to be desired.

Hightec also have an ISO26262 qualified compiler focused on automotive: https://hightec-rt.com/rust
So there's lots of focus on having a good alternative to C/C++

There were a few vendor-specific VLBish busses:
Opti local bus was the most common, and had a few different boards: https://ancientelectronics.wordpress.com/tag/opti-local-bus/
Gigabyte had one that was only used for the "GA-486US" motherboard. The connector was just two 16bit ISA cards back to back: https://theretroweb.com/motherboard/image/ga-486us-front-60b...
I believe there were some others from different vendors.
The signaling for all of these was pretty similar to VLB, since it was just the 486 bus on a connector.

Check out the `--shutter` option for `libcamera-vid`, it allows you to tweak the camera's exposure time which might help with the screen refresh banding. `--shutter 60` sets the exposure time to 60ms, which might be a good starting point.
EDIT: Ah, actually the unit is microseconds, so `60000` would be 60ms

For context, this is the page the cease and desist was referring to.

I wonder how legit this site is. It says:

And indeed, the images seem to be taken from pixabay (e.g. [0], [1]), however the pixabay license is NOT CC0, and specifically forbids redistribution [2]:

Or even find the /etc/shadow contents in the hexeditor and empty the root password field. Searching for "root:" usually gets you to the right place.
Most *nix systems are happy if you pad the left over bytes with newlines, so there's no need to mess with the filesystem metadata or anything like that. :D

I'd never heard of this documentary, so I took a look. I assume you meant "The Bit Player"? ( https://www.imdb.com/title/tt5015534/ ).
It looks interesting, and it's on Amazon prime video so I'll give it a watch. Thanks!

Adding to this:
f-droid also encourages reproducible builds: https://f-droid.org/en/docs/Reproducible_Builds/
This means you can verify the APK on the f-droid store matches what's in github by building it yourself and comparing the signatures.
And if you want to do this, f-droid has an automated way: https://f-droid.org/en/docs/Verification_Server/ Of course, you still have to trust the verification server source code, but that runs locally on your hardware and is auditable.

Rust has a lot of good IDE options these days: https://areweideyet.com/
They decided to focus on the "Rust Language Server", which many IDEs use, rather than on one specific IDE.

As well as the IMA Appraisal feature that mjg59 mentioned, you can also integrity check your entire filesystem with verity[1]. Android uses it to make sure the system partition isn't tampered with.

The embedded version of CLFS (Cross-Compiled Linux From Scratch) covers building a musl + busybox system: http://clfs.org/view/clfs-embedded/x86/
But the more resources available on this kind of thing the better IMHO, there's not really a one size fits all :)
