MetaFilter's commenters do a very good job of pointing out why TermKit, much as it's pretty, is actually a pretty bad idea.

"an application in Snow Leopard cannot use a creator code attached to a document to bind that document to itself." Good coverage here of what happened and workarounds.

I've already got Netatalk running on my funky Debian/Ubuntu hybrid home server but there are some useful tips here (usedot, avahi and custom icons, in particular).

I'd need to change screen -RR (two capitals?) to -Ux, and also distinguish if I've got multiple screens (at home, anyway) but this could be handy.

If Apple was serious about JavaScript, wouldn't there be an implementation of Scripting Bridge? (with apologies to Tom, who mentioned the idea on #2lmc) (and I really should check out Drosera)

mount invocation for readonly hfs on Mac OS X. Very similar to what I use on Linux for my external firewire HDs (`mount -t hfsplus -r /dev/sda3 /mnt/epidermis/`)

I keep forgetting the find mtime syntax

How srm (secure rm) works, because I keep losing the URL

Including fixing bash history from multiple shells, incremental searching, and so on. Old, but good.

Detailed, scathing, amusing and a wonderful last paragraph

Case sensitivity is nothing but a pain.
