How to protect your equipment against EMP?

Electromagnetic pulse (EMP) occurs with a nuclear explosion in the atmosphere.

Simply said it destroys electronics. After an EMP there will be no working radio, television, telephone, power-grid, car or cash-machine.
Banks will stop working and even a millionaire will not be able to buy any food.
People who need medicine or care will have to try without.

Although vacuum tubes are far more resistant to EMP than solid state devices, other components in vacuum tube circuitry can be damaged by EMP.



Protecting against an EMP can be done with the help of a cage of Faraday.
Put your vacuum tube transceiver in a metal box. Make sure the equipment does not touch the metal cage/box. Don't ground the cage/box.

To operate your now state of the art station after nuclear disaster strikes you need power. Remember the power-grid is pre nuclear history and you need your own generator and battery to get up on the air.

(K)ubuntu 8.04 on the HP Mini 2133 (FU338EA)

Finally the screen problems are solved.

Here is how I finally got the HP Mini 2133 (FU338EA) working correctly with kubuntu.

First install kubuntu-8.04.2-desktop-i386.iso

Then install the VIA video driver.
Browse to http://linux.via.com.tw/support/downloadFiles.action
select "Ubuntu 8.04 LTS" and download the stable version.
Extract the files.
Open a terminal and go inside the directory you just created and run ./vinstall
Now download a new xorg.conf file from: https://wiki.ubuntu.com/LaptopTestingTeam/HP2133?action=AttachFile&do=get&target=xorg.conf
Rename your existing xorg.conf file to xorg.conf.old and replace the original one with the one you just downloaded.
To restart the X server press 'CTRL + ALT + Backspace'
If all is well relax and enjoy. Otherwise:

Edit xorg.conf.
change the PanelID value in "Device" section of xorg.conf. Correct PanelID value for 1024x600 is 17 (Add line 'option "PanelID" "17"')
