I updated the Gutsy guide to v1.2, with a lot more added and a few pages meshed together. Some new ideas are in there, along with some refinements to older ones.
Additionally I moved the files off of box.net, which was becoming a bit problematic to update. Their file management tools weren’t cooperating with my browser, and the backup e-mail upload wasn’t doing it either. So I’ve corrected the links and moved them to Mediafile, which is … okay, I guess. Their service seems simpler, and that’s probably for the best.
I’ll look into hosting the files here on WordPress, but I have to pay for the service. I’m kind of cheap, too.

Excuse me, could that trick implemented on Ubuntu 64 bit?
Thanks.
Which trick do you mean?
O, I’m sorry… I mean the “set-up Gutsy for Speed”-Howto.
Most of them should work on 64-bit, but I don’t think you’ll see much improvement. 64-bit machines are usually so fast anyway that the results are too minor to make a difference.
But that doesn’t mean you shouldn’t try. If they work, let us know.
