GPS

Josh notes that "[he] only lost about a week and a half of GPS data, so [his] nerdly autotracking project is mostly uninterrupted." This is a project where he uses a GPS unit to record his comings and goings. While it will in theory geberate some cool maps, it does strike me that it might better be called a Senility Compensation System, since it will enable him to avoid remembering where he has been at various times in the past. Should be a big demand before too long.
