New AiBO+ demo

I forget to write that I reached an other milestone in my AiBO+ project. I have been implemented a brand new PC application with Qt/Qwt to connect to the dog and transfer the robot states to the computer. This new tool was really needed for me to speed up the debugging and the analysis of the sensor and other data. For fun, I implemented custom gestures and ported the application to Windows and Android.

The usual demo is here:

How to clone a hard drive over the network

1. Download the Clonezilla and burn to CD or USB stick.
2. Boot two computers with the needed hard drives with the Clonezilla image.
3. On the source computer follow the steps and select the copy over network from this source computer.
4. During the final steps, the Clonezilla will write on the console what commands should be executed on the target machine.
5. Go to the console on the target machine and execute the needed commands. After a few questions, the cloning will start. Yuppee!

Rfkill hard blocking problem under Ubuntu natty

I experienced hard blocked wlan devices on my HP 2510p laptop with Ubuntu. Like this:

$ rfkill list all

0: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

4: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

The solution was on an Ubuntu forum topic: go to BIOS and restore the defaults.
