Check These Out

Which processes are listening on a specific port (e.g. port 80)

Part of the "atool" package.

intercept stdout/stderr of another process
similar to the previous command, but with more friendly output (tested on linux)

Google voice recognition "API"
The FLAC audio must be encoded at 16000Hz sampling rate (SoX is your friend). Outputs a short JSON string, the actual speech is in the hypotheses->utterance, the accuracy is stored in hypotheses->confidence (ranging from 0 to 1). Google also accepts audio in some special speex format (audio/x-speex-with-header-byte), which is much smaller in comparison with losless FLAC, but I haven't been able to encode such a sample.

Delete all non-printing characters from a file
tr has some predefined sets of characters that are more convenient to use than characters codes

Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

pretend to be busy in office to enjoy a cup of coffee
Create a progress dialog with custom title and text using zenity.
