life is a rum go guv’nor, and that’s the truth
I am a heretic. I develop Rails apps on Windows. I own a Macbook, but I usually boot it into Windows. Justin thinks I should just should just move to developing on a Mac. I keep holding out. But periodically I try to install a gem that needs to compile native extensions for Windows, and [...]

For sometime I have envisioned a web browser that allows me to search and browse all of the web-pages of the world and view them in English. I figure there have got to be lots of cool things going on in the non-English speaking world that I would be interested in but I never hear [...]

Justin and I have been debating whether or not we really believe that Rails can scale. As we talked about this issue, we realized that ozmozr is probably a good test case. We stopped working on ozmozr months ago, realizing that it needed additional work. We needed to move on to other projects we had [...]

I just read an article by SRI researchers that reports on a user study of the Math Tools DL. As one of the participants in the study I was interested to see what they had to say. The basic structure of the report was to: (a) summarize the results, (b) propose representative personas, and (c) [...]
