November Film Roundup:

[Comments] (1) Only g62 Kids Will Remember These Five Moments: Doing a little year-end cleanup in preparation for a big announcement. Back in February I sold a flash piece to Daily Science Fiction: "Only g62 Kids Will Remember These Five Moments". I think it's pretty good. Don't like it? All I have to say is: "OK, g61er."

Openly Public Domain: I was showing Secretly Public Domain to my brother-in-law and noticed that Hathi Trust has marked a lot of the books as public domain! In Hathi parlance, Books that used to be "Limited (search only)" have been made "Full view" (though this is geofenced within the US). You can read the whole book, download a PDF, etc.

This is probably the visible result of the work described in "It's No Secret - Millions of Books Are Openly in the Public Domain", the first known blog post to cast shade on one of my bots with its title. I knew Hathi had done a few books as a test, and now it's really ramped up!

Now we're at the point where thirteen of the last twenty books my bot posted are already "Full view". And notably, the computer-history book I mentioned in the Vice story, The compatible time-sharing system: a programmer's guide., is also "Full view"! Way to go.

Cassini metadata: This year I spent some time doing the pleasant part of botmaking (ideation, data gathering) without the boring part (handling dozens of edge cases, signing up for accounts). One of the bots I never completed was "Cassini GIFs".

All the photos taken by the Cassini probe are online, and each photo has associated metadata. By looking for photos taken by the same instrument at evenly spaced times, you can find frames that would look good as an animation. Here's a nice example: a "movie" of Saturn's moon Dione taken on November 1, 2011:

It was really fun to make these animations that probably only a few people before me had seen. And the fun doesn't need to stop at Saturn: the SETI Project's OPUS3 has aggregated imagery from across NASA's outer planet missions.

The bad news for anyone else who wants to try this out is that the Cassini data is huge. You can download individual frames pretty easily, but the metadata is bundled in enormous tarballs and stored in an ad hoc 1990s file format. To provide a booster seat for the future, I converted the metadata into NDJSON format and put it up as cassini-metadata. Here's one more GIF to whet your interest: Saturn's rings on July 15, 2014:

Olipy3: Right under my self-imposed deadline I've reached my 2019 goal of porting olipy and botfriend to Python 3. Enjoy it! I sure am.
