  • And LaserDiscs can do either! Each one has advantages/disadvantages. CLV has longer runtime, but CAV has better quality and crosstalk properties — one frame is one revolution, so crosstalk from adjacent track is just crosstalk from +/- 1 frame, and it’s “the same part of the frame” in a sense.

    CAV also allows for clean pauses, as it just keeps reading the same frame over and over again, with no need for a fancy buffer.

    You can/could also find Coffee HOWTO in your distro’s HOWTO package. (I found a reference back to v0.5 of the document in 1998.)

    Has simple schematics to get you started for the hardware, using the parallel port to toggle relays.

    It’s a very neat little document, and inspired me to write a simple kernel module so I could echo 1 | sudo tee /sys/whatever/coffee0 to turn pin 0 high on the parallel port. (This is silly, and it’s much easier to just do things in user space!)








  • Cool, I recommend it!

    I have my public facing reverse proxy point to my public services, and I also have it set up as a “roadwarrior” VPN to my home. So, I can connect my phone via WireGuard to my VPS, and a local DNS resolves my private services to the private IP addresses in my home network (so, I also run a reverse proxy on my server, for internal services).

    I also have an off-site backup using this — just a raspberry pi and an HDD at family’s, that rsyncs+snapshots over the WireGuard network.

    I’m sure I’m not following all the best practices here, but so far so good.
