Michael Brewer has a good article on O'Reilly's Mac DevCenter that covers .Mac pretty well. It also links to Rael's article about WebDAV on Mac OS X, which I found very useful.
Simon has hit on something that really bothers me about the "Perl Community"--the way it often rewards arrogance and spwans cults based upon those in the inner circle. It's sad to see Simon go, but it's clearly better for him this way.
Earlier, Dan pointed me at this amusing story at Recoil. I had never heard of Recoil before, but it feels a lot like The Onion. Give it a read today.
Maybe you've switched and are now wishing to have the Alt-Tab feature present in the operating system you left. Have a look at Lite Switch X, it's probably just what you need.
I fail to understand why some folks make it difficult to find the URL of the RSS feed for the weblog. Take, for example, Simon Cozens. Do you see a link anywhere for the RSS? Nope. If you view source in your browser, you'll see it near the top. But why not put it where humans can see it too? You know, the kind who want to cut-n-paste it somewhere?
Another example is all the weblogs hosted on O'Reilly Net, like Andy Oram's or Tim's. Where's the RSS feed? Do they not get it? My RSS software wants URLs to watch for headlines...
I have to agree with the Fuzzy One. Dave is on crack. Open Source is not slavery.
A helpful article at LinuxOrbit. I've always thought the process was a bit under-documented. Luckily, I don't really need to build custom kernels for my Debian boxes (except my laptop, which I have no plans to update).
