(Another “piecemeal” post. Yes, I know: I should write more often.)
I cycle through one-off passwords (of varying lengths). To generate these, I use the following shell script:

#!/bin/bash
 
usage() {
echo "Usage: `basename $0` [length]"
}
 
[ $# -gt 1 ] && usage && exit 65
 
[ $# -eq 0 ] && len=8 || len=$1
 
strings /dev/urandom | grep -o [...]

Update: As Pádraig Brady, fslint maintainer, pointed out: fslint/findup *is* a shell script.

Picasa 3 for Linux has this niggling* problem: you can’t log on to Picasa Web. [...]

We already know how to update Twitter from the command line. To get your and your friends’ timeline from the CLI, use the following one-liner:

curl -u username –silent "https://twitter.com/statuses/friends_timeline.rss" | perl -ne ‘print "$2\n" if /< (description)>(.*)< \/\1>/;’

Using the same method, you can also get unread Gmail inbox messages (via commandlinefu.com).
