Other projects

My main project at the moment is ChicagoLocalMusic.net. It's one email a week with all the shows from bands you follow and a few from bands you don't; check out the features page for more info. (free as in freedom! self-hostable for other cities! open source!)

With my chevruta, I made eitz-harabanim.com, a "family tree" showing the teacher-student relationships among Rabbis in the Talmud (source).

I was formerly a practicing physicist and have some papers published that I'm proud of.
