Linux kernel development future, 2008

If you are interested in the state of the linux kernel watch this video from Linuxcon where Linus and his main lieutenants talk in a round table:

To be able to encode mp3 files with Sound Juicer on Ubuntu Jaunty Jackalope just install the package gstreamer0.10-plugins-ugly-multiverse.

If you then open sound juicer, in the preferences->output format->edit profiles you can now see the CD Quality, mp3 option.

The first time I ran it, the output format didn't had the mp3 option. I just edited the mp3 profile and tick two times the active checkbox.

Don't know if this is really necessary but now everything works. :D

Just found out an incredible little python library to plot very nice looking graphics: CairoPlot.

Let's do a brief quick tutorial:

• First install bazaar version control system (if you don't have it)

sudo aptitude install bzr

• Go fetch the cairoplot version 1.1

bzr branch lp:cairoplot/1.1

• Now in python import the libraries

import CairoPlot
import cairo

• Create some data

data = [1,3,3,2,4,5,6,7,12,7,3,1,2,3,4,6,7,8]

• Draw the graphic

CairoPlot.dot_line_plot('example.png', data, 400, 399, axis=True, grid=True, dots='true')

• Now check out the image at example.png

For my academic research I will still continue to use gnuplot, but I must admit CairoPlot images look a loot prettier. A great kudos to the authors.

If you want gnome's top to be completely invisible (height=0) when it is hidden just:

1. Run gconf-editor
2. Go to apps -> panel -> toplevels -> top_panel_screen0
3. Change the auto_hide_size key from the default value of 6 to 0

Just to explain the differences, here's before:

Here's the top panel completely invisible after:
