I wrote a fun sed script today: sed -E -n -e ‘:t ; s/(.{21})(.*)/\\bf\{\1\}\n\2/ ; p ; s/\\bf\{(.*)\}\n.*/\1/ ; h ; :q { n ; G ; s/(.{21})(.*)\n\1/\2/ ; tp ; s/(.+)\n.*/\1/ ; bt} ; :p { P ; bq }’ Short, but effective. Can you figure out what it does? (solution after the break)

So it was pretty inevitable that I would end up purchasing one of their WebOS products, even though there’s not a lot in common between this [...]

It’s an extremely convenient way for computers to represent the time, since it’s just an integer that goes up. There’s no parsing to be done, and arithmetic [...]
