Copy files over network using compression

This is useful for sending data between 2 computers that you have shell access to. Uses tar compression during transfer. Files are compressed & uncompressed automatically. Note the trailing dash on the listening side that makes netcat listen to stdin for data. on the listening side: sudo nc -lp 2022 | sudo tar -xvf - explanation: open netcat to -l listen on -p port 2022, take the data stream and pipe to tar -x extract, -v verbose, -f using file filename - means "stdin" on the sending side: tar -cvzf - ./*| nc -w 3 name_of_listening_host 2022 explanation: compress all files in current dir using tar -c create, -v verbose, -f using file, - filename - here means "stdout" because we're tar -c instead of tar -x, -w3 wait 3 seconds on stream termination and then end the connection to the listening host name_of_listening_host, on port 2022
This is sample output - yours may be different.
-2

on the listening side: sudo nc -lp 2022 | sudo tar -xvf - and on the sending side: tar -cvzf - ./*| nc -w 3 name_of_listening_host 2022

Turn Regular quotes ("") into curly quotes (??)

Turns regular quotes into curly quotes, also converts hyphens to dashes using a heuristic and outputs the result as UTF-8, suitable to copy/paste into wordprocessor. requires: http://daringfireball.net/projects/smartypants/ (which does most of the work) (I renamed smartypants.pl to smartypants before adding it to my $PATH) Also requrires PHP with the multibyte module installed (its installed by default with PHP, but the sysadmin on one server I use disabled it... presumadly to increase performance or something).
This is sample output - yours may be different.

Transform a portrait pdf in a landscape one with 2 pages per page

This is an example of the usage of pdfnup (you can find it in the 'pdfjam' package). With this command you can save ink/toner and paper (and thus trees!) when you print a pdf. This tools are very configurable, and you can make also 2x2, 3x2, 2x3 layouts, and more (the limit is your fantasy and the resolution of the printer :-) You must have installed pdfjam, pdflatex, and the LaTeX pdfpages package in your box.
