Using DBUS to take action on a USB storage device

I keep my password-encrypted SSH and PGP keys on a small USB key.  I do this to keep these sensitive files separate from my laptop, in case I were to lose it.  I figure it’s easier to keep a USB … Continue reading →

Server Room Temps

I have an over-sized A/C unit for my server room, which is both good and bad.  It's good because I have plenty of capacity and can keep the room at 64 degrees in 100+ degree weather (if I so desire) … Continue reading →
