fixing ethernet under lucid

Got a very new computer. Precise works like a charm on it, but no internet connection under lucid. Network card is unclaimed, because the driver is too old.

Download the latest e1000e from sourceforge (2.1.4 at the moment) in /usr/src and extract it. Then create the following dkms.conf in the e1000e directory:
PACKAGE_NAME="e1000e"
PACKAGE_VERSION="2.1.4"
CLEAN="make -C src/ clean"
MAKE="make -C src/ BUILD_KERNEL=$kernelver KERNELDIR=/lib/modules${kernelver}/build"
BUILT_MODULE_NAME[0]="e1000e"
BUILT_MODULE_LOCATION="src/"
DEST_MODULE_LOCATION="/updates"
AUTOINSTALL="yes"
REMAKE_INITRD="yes"
Then 
dkms add -m e1000e -v 2.1.4
dkms build -m e1000e -v 2.1.4
dkms install -m e1000e -v 2.1.4
Note:
Without an internet connection it's pretty hard to install the required packages like dkms, so the trick is to boot into Precise and then chroot into Lucid.

Vehicle platooning in the EU

http://www.euronews.com/2012/09/24/test-driving-a-road-train/
The EU funded SARTRE project (Safe Road-Trains for the Environment) is working to develop what is called vehicle platooning. This means that only the first vehicle has a driver. Developers hope that the idea will improve safety, efficiency and mileage, will reduce journey times, road congestion and pollution from cars. Various surveys have shown that 90% of accidents are due to boredom while driving on motorways, but with SARTRE a car can drive itself up the motorway. 

The idea has been around for a long time, maybe over 20 years, and there has been many attempts at it. Maybe this time it's the right attempt. After all the technology has matured a lot, and latest legal developments with the Google car make autonomous vehicles seem more realistic.
