I'm sad that JSONSelect ( https://github.com/lloyd/JSONSelect ) never caught on. It uses CSS selectors to query JSON, which has the nice side effect that learning to use it improves your CSS as well!

Ocropus is fairly actively developed. Lots of commits in 2015: https://github.com/tmbdev/ocropy/commits/master

I wouldn't say that Ocropus is well-documented (this blog post was partially intended to address that). But it's at least written in easily hackable Python, whereas Tesseract is 30 year old C/C++.

I really enjoyed OhLife. Reading your own writing is the best way to improve it. OhLife helped you do just that. The one additional feature I'd like to see in an OhLife replacement is the incorporation of some cues about my day to help

Any thoughts on Closure Compiler vs. typescript? One thing I like about Closure Compiler is that it lets you explicitly list the symbols you wish to export from your JS, which is a huge boon for code minification.
