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.
You can ran this also with cat for example:
tar zcvf - /folder/ | ssh email@example.com "cat > /dest/folder/file.tar.gz"
Or even run other command's:
tcpdump | ssh firstname.lastname@example.org "cat > /tmp/tcpdump.log"
Create a secure tunnelled connection for access to a remote MySQL database.
For example, connect with MySQL Workbench to email@example.com:13306.
1. SSH into a machine
2. Tunnels VNC port to your local computer ("-L 5900:localhost:5900")
3. Runs a single use vnc server ("x11vnc -safer -localhost -nopw -once -display :0")
4. Goes into the background ("-f")
5. Runs VNC viewer on the local computer connecting to the remote machine via the newly created SSH tunnel ("vinagre localhost:5900")
