It's amazing how free software can be flexible. The last weeks I've needed several times do configure printers remotely. Sometimes it's "scary" what can be done with CUPS, ssh, and LinuxPrinting.org.

As I know (since last year, in fact) live 3000 km away from my hometown, and these days my parents bougth a new printer, those software came into hand to solve the problem. :-)

To configure "locally" a remote printer:

ssh remotehost   -L 9999:localhost:631

This way the CUPS web configuration interface on remotehost will be available on http://localhost:9999.

perl -p -e 's/_//; s/^(.)(.*)$/\u$1\L$2/;'
It will be usefull ... ;-)

Gives:

pt_BR -> Ptbr
en -> En

I'm used to imperative programming Languages, but I've started to read the book An introduction to functional programming systems using Haskell.

Functional Programming Languages have looked ugly for me, because of my (small) previous experience with Lisp. All those parentheses were very boring.

But Haskell has an extremely simple syntax, is very expressive and has direct and straighforward constructions. I've thought about programming something "real" to experiment using Haskell for programming usual stuff.

I hope I get used to program without attributions. :-)

I'll start to write here about all stuff I do with/for free software.
