I miss BosnianBill, it always felt like my grandpa was sharing his hobby with me.
LPL and BB got me into picking locks, and so far it's saved a couple of massive personal headaches and one extremely expensive piece of industrial equipment (for which I recieved absolutely no recognition in saving the company about $450,000-550,000 in broken equipment)
It's also a fun quick thing to teach people and I have a spare set with me and an acrylic demonstration lock to show newbies.
I had fun at a park in south-western ohio once when I started picking all the padlocks couples were leaving on a bridge. I left about a dozen of them sitting on top of the railing.
Fun times, cheap hobby.
Someone who wants to make super sure that no dust gets into the discs, as even a single mote of dust in the drive will set off a chain reaction that destroys every universe simultaneously.
At least, according to my mother. She always insisted that floppy discs be stored like this since dust could settle in the tab if left the other way.
