Well, ruby is actually so flexible that there is no real need to implement the goode olde signals & slots metaphor. But it serves nicely as demonstration of ruby properties, so here we go.

Command Line Calculato

KillProc will do a search of all the current processes and kill all that
match the name given. If the process name is misspelled, KillProc would
kill itself, based on the match. The 'find /v /i "KillProc"' part of the
search prevents KillProc from killing the CMD window it is running in.

I've found it kind of complicated to strip newline chars from a file with just the commandline. This tiny piece of code does just that.

I've found it especially useful when extracting tabulated data from a grabbed site where each cell is on a different html line. This way I can pre-filter the html, remove the newlines, and insert them again at register boundaries (row end in this case), so that with just a couple more replacement from within a regex enabled text editor I can copy&paste it directly to a database.

I'm in the process of writing test fixtures for our rails site. A lot of my tests require authentication, so I've had to port our permissions system into a fixture. Rather than type out all of the information for the fixture, I decided to create a nested loop that will take care of this for me.

There's probably a rake task for this, but I wasn't able to find it, so I came up with my own solution. You'll have to do a little cleanup when it's done, however some slight mods to this loop could even eliminate that.
