I tracked down the unidentified H500 helicopter from the previous journal entry. It turns out it's N220PD, an Oakland PD helicopter. I also used it to find out about N137HP - one of the CHP's surveillance aircraft.

It's been hard to be motivated to do any technical stuff owing to the state of the world. That being said, I've been wanting to do work on the knowledge graph system, and I've been interested in learning more about quantum computing.

I'm still slowly [1] working through The Architecture of Symbolic Computers.

On knowledge graphs

I want to explore PostGIS (for locations), and Neo4J (a graph database). Maybe a combination of the two? I'm not sure. There's a lot of reading to be done in the area of KGs, too, a lot of prior work to read up on.

On quantum computing

I picked up a copy of Programming Quantum Computers and I'm trying to make some progress on that. At the same time, I'm trying to use Rigetti's QVM to experiment.
