Not a huge hardware synth fan (I like software and do not have space) but I do have a thing for EA-1/MS-2000/Microkorg. They are kind of like "same family".
If (actually more like when) I buy a bigger house I'll get used MS-2000 :-) It's quite limited compared to e.g. JP-8000 but has tons more character.

Process specific ABI (psABI) specification can take dozens of pages in total. For RISC-V the spec has 95 pages. It is not ergonomic to print it all, so what to print out?
I usually print just the section enumerating the relocation's. It is the nastiest differentiatior and the part one is most likely continue to revisit forever after 🙂 For RISC-V that totals six pages.

After trying bunch of things over the last few weeks I finally have a test program for feeding the data for a video loopback device, i.e. to work as fake webcam:
- Has zero dependencies other than libc. Draws the frames, converts the pixel formats and writes them to the device.
-.Has optional debug display using minifb.
- Predictable cyclic motion, which useful in future for automated testing.
Repository: https://codeberg.org/jarkko/v4l2-loopback-test/
BuildRoot package: https://codeberg.org/jarkko/linux-tpmdd-test/src/branch/main/package/v4l2-loopback-test
I've not been able to make any major changes to the driver I would like to do because it does not make much when being blind. Now it is finally possible to forget user space and move on to the kernel changes.

Next making a fake webccam program with Rust to have something to run as the server end with the in-kernel driver using anonymous inode for proxy.
Realized that I need this before doing API split (i.e. break).
I'll implement it with Bevy and it will stream a rotating torus (that weird thing in the middle ATM) to the video loopback proxy

I've been trying to recall this place a few times but now I bumped to a pic in my NAS. Terraza @ Brno, Czech. Best long drinks! Need to visit here some day. The pic is from 2020 :-)

A TOR search engine that my friend Juha has made some years ago: https://ahmia.fi/
Ahmia is like "big eater" someone who eats all food you have.

1. My calendar for 2025.
2. My security tip for 2025: use pen and paper for what it works. That info does not leak. I still plan and draft with a notebook (having a grid) and pencil.
