commandlinefu.com is the place to record those command-line gems that you return to again and again.
Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.
If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

Requires software found at: http://lpccomp.bc.ca/remserial/
Remote [A] (with physical serial port connected to device)
./remserial -d -p 23000 -s "115200 raw" /dev/ttyS0 &
Local [B] (running the program that needs to connect to serial device)
Create a SSH tunnel to the remote server:
ssh -N -L 23000:localhost:23000 user@hostwithphysicalserialport
Use the locally tunnelled port to connect the local virtual serial port to the remote real physical port:
./remserial -d -r localhost -p 23000 -l /dev/remser1 /dev/ptmx &
Example: Running minicom on machine B using serial /dev/remser1 will actually connect you to whatever device is plugged into machine A's serial port /dev/ttyS0.
