I spent the last hour re-familiarizing myself with Unix sockets via man-pages and HOWTOs. I have written client/server socket apps a dozen times before but because of iterative development I no longer had a simple example lying around.
To save myself this trouble in the future I created a little socket client and server for future reference. This app allows you to have a Twitter style conversation (140 char limit) with everyone on your system who has permissions to the Unix socket! Perhaps the Unix shell is the next micro-blogging platform. ;)
