It's intented to be an index with interest links and docs. Code As you probably know, I like to code a lot. Here I put some pieces of code that I think are useless, but if you can give them a nice touch then you can use in your own apps. It's language categorized. Enjoy as much as I do. text/html 2010-02-02T10:12:16-07:00 positron http://www.positrones.net/wiki/doku.php?id=geektips:record_webcam&rev=1265130736&do=diff Record Video and Audio from WebCam with Mencoder Sometimes we want to record video and audio from a webcam, in my case I can use my PV-GS39 as a webcam, so when I connect it, my GNU/Linux box create automagically 2 new devices: * /dev/video2 This is the v4l device. * /dev/dsp1 This is the audio provided by the microphone of the camera. text/html 2009-12-28T12:53:31-07:00 positron http://www.positrones.net/wiki/doku.php?id=devel:ruby:cipher_decipher_data_with_openssl&rev=1262030011&do=diff The next class works with the openssl module for ruby.

Anyway, he said to that I try to make Ruby natural, not simple. It's one of the languages that I fall in love and never let go away(yes, C is the another one).

Really, I don't like so much, but it's so much easy to learn and use and, as a friend said once: Java it's a big Lego's box, just put the pieces together and it works!.
