I'm working on a bunch of stuff at the moment:
At work:
We are in the early stages of moving our servers (some 1300+) from freeBSD to GNU/Linux. So, yeah, working on a very customised Funtoo fork including an install CD (which currently Funtoo/Gentoo doesn't have).
Development wise Iv'e been spending most of my time rewriting / upgrading large portions of our framework including our DAL and have also been implimenting some cool stuff on the front end using Backbone.js and Mootools (I'd rather be using jQuery, but whatever).
Personal Stuff:
I've been very slowly developing a site for lovers of experimental electronic music (one of my other hobbies) using Rails, Node.js and Backbone.js. I've been plugging away at this site for about the last 8 months, I'm still not sure I'll ever be happy enough with it to actually launch the thing.
I'm just starting to get some traction pushing packages to Funtoo/Gentoo.
And yeah, still (when I get time) playing around with my own PHP MVC, though I havent made a commit in about a month.
