how to encrypt and decrypt a tar, one-liner version
I do love one-liners that I can do on the command line in Linux, and this one has to do with TAR archives.
TAR, on its own, doesn't encrypt anything. This being true, a separate utility has to be used to encrypt it. The easiest one is GPG.

i'm glad arcade machines are somebody else's problem
One time in my life I had an arcade machine in the house. It was a video arcade game, Mortal Kombat 3. I think I had it for a year or maybe slightly longer, then sold it. I've no regrets about that whatsoever.
