On 11 August 1987, Apple released the “software erector set” HyperCard at Macworld Expo in Boston, and while it hasn’t been with us for many years now, back then it made a huge difference in the lives of Mac users, enabling many to give life to ideas that would otherwise never have seen the light of day. That might include even TidBITS, since we published our first 99 issues in HyperCard format, in a stack that could import its content into a searchable archive. Without the thrill of publishing in an entirely new format, it’s possible that TidBITS might have fallen by the wayside.

Single Time Machine Backups
Tired of Time Machine running all the time? You can turn it off in the Time Machine preference pane, but still initiate a single backup by choosing Back Up Now from Time Machine's menu bar icon. Of course, your backup is much less likely to be up to date, but Time Machine won't be taking any resources while you're trying to work.
