I'm working on bitcoinp (
https://github.com/hmsimha/bitcoinp) and a couple other projects I've yet to push to github, but which I'll describe anyway:
Bitcoinp ("bitcoin, with padding") is a jsonp enabled api that aggregates api data from the most popular bitcoin exchanges (and platforms that 'provide bitcoin exchange services' such as coinbase) and delivers it to anyone who wants to make it visible on their page (client-side), so they don't have to build a backend to do the same thing. I think it will be useful to people just cutting their teeth on html who've maybe set up a neocities, as well as people making browser extensions or phone apps that want to deliver a customizable view on bitcoin prices, or deliver something similar to http://preev.com
I'm also working on an API intended to be used by chrome extensions that wraps google's diff-match-patch library and allows content script writers to enable their users to easily track and visualize changes to sections of the webpage they modify.
I'm also also working on an easier way to manage resume changes that would run as a single-page application.
I'm also contributing to open-source projects that interest me: most recently submitted a bug fix to tubalr.com, but I'm also planning some contributions to the Reddit Enhancement Suite.
