my twitter stream is/was very local to my city. i dont know how to replicate that with toots. I want to send a message only to those people who live in my city. If I could group followers inside mastodon, that'd be helpful. Or if my followers list itself were a seperate service that I could manage and group and they'd show up anywhere I wanted. Google Circles was ahead of its time and also shot itself in the foot with no API.

One upside of the Google Music interface being not very good for discovering music (and perhaps no platforms are), is that I have to come up with band names myself. I enjoy lots of music but never payed too much attention to having particular music available. For instance, techno podcasts were a big source of music for a while. Now I'm having fun thinking of a band name that is famous but I probably dont know at all and just listen to an album of theirs. Today includes The Ramones.

The Blender project is posting new videos on their instance of peertube and the notices are showing up in my mastodon feed. The fediverse is pretty great.

the bitcoin cash fork happening today has two sides both with many megawatts of hashpower at their disposal. the changes in hashrate on each side is a tug-of-war played with electricity, silicon, and human organization (mining pools).

I recommend The Last Days of Night about the 1850s electrification of New York City and the legal battles between Edison and Westinghouse (and Tesla).

cellphone based augmented reality is still a great idea. why doesnt a game like this exist?

This trailer for "Shadow Cities" is from *2010* and to my knowledge there isnt a game like it outside of the Niantic franchises.
