Bringing the same precise timing capabilities of its calendar entries to reminders, Flexibits has released Fantastical 1.3.11 with the addition of a due time field when you select Due Date in a task. The calendar app also fixes errors when using iCloud, an issue that prevented Outlook events from updating, a bug that made Fantastical appear partially offscreen when using multiple displays on OS X 10.9 Mavericks, and a potential hang when creating events with invitees on Mavericks. ($19.99 new, free update from Flexibits and the Mac App Store, 11.7 MB, release notes)
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.
