Ah, to return home after an extended tour of Boston and the Northeast, complete with an ongoing bout of the Martian Death Flu. There's nothing like returning to hundreds of messages that I didn't read while on the road (mostly mailing lists, luckily) and to a foot of snail mail. In the confusion, I managed to accidentally send two personal messages (and a quick apology) to all 9,600+ people on the TidBITS mailing list, resulting in a number of messages from people who were relieved to see that even we so-called net experts can screw up royally from time to time, proving that we're only human. Or perhaps we're actually sophisticated artificial intelligences? [ACE]
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
