Keylay
I use Keylay to remap the keyboard in Windows. I set the two alt-keys (those closest to the spacebar) to be shift, so I do not have to strike them with my little fingers which tire easily.
Unison
I use Unison intensively to synchronise my research data between machines, and for other backup-related tasks.
Document processing and window managers.
I use LaTeX with VIM. Long ago I used Emacs, but a friend showed me VIM and I discovered I liked it. In fact, I prefer the command line. I used Ratpoison, then Ion2 (for its tabs), switched KDE found it too bloated, so used Fluxbox. Hardware and KDE have improved much, so I'm now back with KDE.
TV (programmes)
Discovery channel, UKTV and similar channels, are wonderful. There's generally something of acceptable quality on one of them, and the outstanding is not infrequent. I read all day for my profession, thanks to this wonderful modern development, I can switch on the telly for a change and get something worthwhile and interesting. It makes such a difference.
