I’ve been active on the programming question & answer site, for a few years now, and in the past several months, the company behind that wonderful resource has branched out into other topics.  This week, the new site launched in public beta. The software this site runs on is finely tuned for asking […]

Prioritizing Netflix traffic with DD-WRT

Network traffic shaping is an interesting topic, that allows you to ensure that certain traffic gets priority over other traffic.  When applied at the ISP level, this can get controversial, as you start getting into Network-Neutrality issues (where one company’s traffic gets priority over another company’s, which could lead to large media corporations silencing grassroots […]

Experimenting with Panoramic Photography

On a recent backpacking trip to Yosemite National Park, I decided to experiment panoramic photos. There are so many astounding views from the heights above Pate Valley and the Grand Canyon of the Toulomne, I was hoping to capture at least a fraction of that beauty with my camera. Now, I don’t have a fancy […]

Bottle Conditioning in Growlers

Well, today seemed to be a busy day for people asking me beer-related questions on facebook. I like to repost things like this here, since the facebook wall doesn't really stick around very long.
