There is a new blog you should check out: OpenSourcePhotography.org. It deals with, believe it or not, OpenSource stuff and Photography stuff. There is some real potential there, I hope it develops.
There is apparently a big fight among OpenSource community members about whether or not Ubuntu (pronounced Ubuntu) gives back to the community. In my view, not knowing much about the debate, the fact that the vast majority of desktops and laptops that run Linux these days do so because Ubuntu did what it did should be plenty, but apparently there is more to it than that. The fight, really, is about code. Read about is here: Ubuntu Empire Strikes Back
