ZeitgeistPowerTOP
Whenever we need to check which process is consuming most CPU we use the TOP command or HTOP command. Then you can kill processes consuming resources unnecessarily on your GNU/Linux system.
But yesterday I discovered (thanks Marcos) the PowerTOP command:
- Show how well your system is using the various hardware power-saving features
- Show you the culprit software components that are preventing optimal usage of your hardware power savings
- Help Linux developers test their application and achieve optimal behavior
- Provide you with tuning suggestions to achieve low power consumption
For me the last characteristic is great in order to save battery and power consumption.
By the way…I killed skype (mandatory binary installation, because skype is not OpenSource) since it was devouring my CPU 
Fixing skype audio problem on Ubuntu 9.04
via this blog I discovered how to be able to use skype without problems in ubuntu 9.04
In spite of not being open source skype is always useful to make private calls to the family Enjoy the solution:
When running Skype on Ubuntu 9.04, you will get the following error message when making a test call:
“Problem with Audio Playback”
The problem is that Ubuntu uses pulse audio and Skype does not play nicely with it. To fix it, do the following:
- Open Skype options and select Sound Devices
- Change Sound In, Sound Out and Ringing to use “pulse”
- Clear the check mark next to “Allow Skype to automatically adjust my mixer levels” (This step may not be required)
- Press the Apply button and then the Close button.
You should now be able to place a test call.
Adobe Flash Player problems with fullscreen mode in Firefox and Ubuntu 9.04
Since I upgraded to Ubuntu 9.04 (a.k.a. Jaunty Jackalope) I found some problems when watching videos via Flash media player 10 in fullscreen mode.
After doing a small research the *only* solution that really solved the issue is explained in this thread
What you have to do is easy:
- sudo mkdir /etc/adobe
- sudo nano /etc/adobe/mms.cfg
- Paste “OverrideGPUValidation=true” (without quotation marks)
- Restart Firefox.
I hope this solves the problem.
I am looking forward to the next Adobe Flash Player release
Open Source…in hardware?
An interesting article presenting the incoming revolution in hardware…open source!
Could cell phones become open source? Different initiatives like OpenMoko will make it real

Running as a way of life
Today one of my best friends (take a look at his blog: MikiMaraton) made me re-discover running as a perfect way to keep strong mentally as well as for proving yourself that YES, YOU CAN!
We ran along the seafront between El Masnou and Sant Adria del Besos (both located in the mediterranean coast of Catalonia), a total amount of 20 km (see the exact route). Being honest, the last meters were really exhausting but as Miki told me: “Do not let your body to be stronger than your mind”
Happy birthday Unix: 40 years!
At the beginnning of the 70’s two scientists (Ken Thompson and Dennis Ritchie) created the Unics operating system, afterwards called Unix. Apart from the first edition of the “Unix Programmer’s Manual”, Dennis Ritchie gives the C language to the humanity. The pipe mechanism was born to provoke a revolution, leaving the assembler in the past for Unix.
Today the history has to say thanks to these two geeks who created the base for Linux/BSD among other efficient and powerful operating systems.
Here you can see a good diagram of the evolution of Unix into Minix, Linux, Mac OS X, FreeBSD, Net BSD, OpenBSD, Solaris, Open Solaris, etc.
3,2,1…go!
We live in a different world every day: technology, globalization, crisis, war, peace, soccer, poverty, progress, etc…everything makes our world different, challenging and interesting offering tons and tons of information, opportunities and challenges.
Since sharing knowledge and points of view is worth enough to start a personal blog I decided today, 7th June 2009, to write my first public words in the Cyberspace.
As starting point I would like to remind you the Declaration of Independence of Cyberspace:
Governments of the Industrial World, you weary giants of flesh and steel, I come from Cyberspace, the new home of Mind. On behalf of the future, I ask you of the past to leave us alone. You are not welcome among us. You have no sovereignty where we gather.
– John Perry Barlow, “A Declaration of the Independence of Cyberspace”
