You must allow port 6600 in firewall.

$ sudo ufw proto tcp from 192.168.1.16 to any port 6600

192.168.1.16 is only my example, you must put your Raspberry Pi IP address !!!

No result when attempting to repaire battery in freezer

I read on a forum, it is possible to repaire a battery when you freeze it in the freezer.
I packed the battery in a plastic bag (zip-lock) and I put the battery in the freezer for 24 hours.
The temperature in the freezer is -18ºC.
After 24 hours I took out the battery from the freezer, I unpacked it from the plastic bag, and cleaned it.

I inserted the battery into my computer and charged it for 8 hours.
After 8 hours of charging, my battery still worked for 20 minutes as before.

The myth to repaire a battery in a freezer is not possible.
It does not work for me.

Transparent desktop text icons xubuntu 12.04

Create a file named .gtkrc-2.0 in your home directory.
Open this file in a text editor and fill it with the text:


style "xfdesktop-icon-view" {
XfdesktopIconView::label-alpha = 0

fg[NORMAL] = "#ffffff"
fg[SELECTED] = "#ffffff"
fg[ACTIVE] = "#ffffff"
}


widget_class "*XfdesktopIconView*" style "xfdesktop-icon-view"



If you want to change the text colour as well, just edit the file replacing ffffff with the desired colour's code (tip: you can use Gcolor2 to help you determine the colour code).
For the changes to take effect either log out and log in or run the command:

$ killall xfdesktop

And wait for xfdesktop to restart.
