snippetUsing mencoder in Linux, we can convert any video to FLV and embed it in a web page with Flowplayer. In this sample video is encoded at 320×240 300 kbps and audio at 56kbps:

snippetWith pdftk we can (as well as a lot of other PDF-related operations) join PDFs in Linux, wich is something very useful. This is one example:

# pdftk file1.pdf file2.pdf file3.pdf cat output file_output.pdf

For windows there is also Pdftk Builder, with a graphical interface.

snippetEsta herramienta nos permite generar screencasts (grabaciones de nuestro escritorio) en formato GIF animado (sin sonido, claro). Por ejemplo, para generar un screencast de 60 segundos, y que espere 2 segundos para empezar a grabar:

# byzanz-record -c -d 60 –delay 2 screencast.gif

La -c es para que grabe el movimiento del cursor.

Hay otros programas para grabar screencasts, como Istambul pero éste no me funciona bien en mi Debian Squeeze.
