During covid I needed to setup remote piano lessons. I tried combining two videos to show hands on the keys as well as the face but at the time merging the two videos added too much latency. I solved this by only using the top down camera and then adding clear perspex (from a plastic picture frame) at 45 degrees in front of the raised laptop and also pointed lamps at the piano players face (the effect is called Pepper's Ghost). This meant the teacher could see the hands on the keyboard and the players face with one camera. It also meant the piano player would appear to look directly into the camera - like an auto cue. I'm posting here in case it helps someone else.

I think the Dutch bike experience is the result of a conscious decision to make cycling feel safe and convenient which was partly motivated by the 1970's fuel crisis. The real puzzle is why is this the only country make that decision. See also http://www.aviewfromthecyclepath.com/2009/10/effect-of-hills...

I have been thinking about this lately and found this last week http://www.ats-lang.org

I have seen Boxer referenced and it seems like a great idea. Did it lead to something else and if not is there a good reason. I'd like to know more about it but the name makes it hard to search for. Is there a way to run it?

I don't know if this is the kind of thing you had in mind but you could try monetdb. I ran some tests a while ago and it performed very well.

If spotify support is needed www.mopidy.com is probably the way to go. It implements the mpd protocol and plays local files, spotify and others.

This is a lot like a project I have been working on: https://github.com/thomasrynne/swisher which uses cheap RFID readers and a raspberry pi. Does anyone know how this one works?

Re vinyl: It takes longer to choose a song, records can get scratched and take up more space. My intention was to try to make the best interface to play music. Now that the media is digital there are less restrictions on the physical interface but I think tangible items associated with each track/radio station is still good.

Grabbing a helmet isn't like wearing a seat belt. The most a helmet does is reduce minor injuries. There's no evidence that they save lives.
