Re: [PLUG] Correct Horse Battery Staple

["K.S. Bhaskar via plug" <plug@lists.phillylinux.org>]

Horse battery staple is a terrible idea. If you have to remember five random sequences of four words each, you can, but if you have to remember 20 (most people have logins for at least e-mail, social media, banking, etc.) it's questionable whether you can. Horse battery staple may be a good idea for a master password for a password manager, but that's it; certainly not for a bunch of accounts. Instead of random sequences of words, most people will end up using meaningful phrases like “Mikey's high school PTO” which have far less entropy.

I remember studies from way back when: while chess grandmasters can remember meaningful chess board positions far better than average people, when it comes to random chess board positions, they are no better than average people. It's the same thing with random phrases vs. meaningful phrases.

I may have talked about this before, but it came up at work Friday, so...

Go read https://xkcd.com/936/.

Then try:
`alias randomwords="shuf -n102 /usr/share/dict/words | perl -ne 'print qq(\u\$_);' | column"`
