Fireplace floor protector progress! Something covering the floor cuts remaining, and of course some firewood. The finish got a little weird because of dust where I painted, but meh. The cutouts turned out so good that I didn't need to seal against the blocks. Really fun project overall!

Finishing of new oak shelves for the kitchen. Some pigmented linseed oil/wax on them and we're good to go.

Office upgrade project in progress! The bookshelf is taking shape, just need to mount it next to the IVAR cabinets and cut out the remaining shelves.
Probably finishing it with linseed oil for now. Maybe paint later, but I like the fur against the olive green wall.

Unicode success, finally. (Pandoc is doing the heavy lifting.)

Getting there! This is the actual output right now of my website-to-book tool running on docs.quickstrom.io, not a POC.

I've been hacking on the scraper a lot, trying to get TOC extraction robust. It now handles links in all weird directions (as often seen in Sphinx sites). No JS support yet, but that's probably coming up next.
I'd be happy to receive test cases I can use.

Proof of concept using Pandoc! Here I'm converting my own blog into an ereader-friendly PDF. I'd spend a lot more time making the output beautiful, as I think that's one of the major selling points. Need to build a real crawler, possibly running a real Chrome to support JS.

`rainbow_log` is becoming surprisingly useful!
It takes a regex, runs that on each line, and colors matching lines uniquely based on the matched substring.
