Home made HERF guns
A blog article reflecting on HERF guns has just been published on John Robbs’ Global Guerrillas web log.
For those of you who don’t know what a HERF gun is here I reproduce an excerpt from the Wikipedia entry:
HERF or High Energy Radio Frequency weapons, also known as HPRF or High Power Radio Frequency weapons are weapons designed to use high intensity radio waves to disrupt electronics. They operate in a similar way to EMP devices, by inducing destructive voltage within the electronic wiring. They are usually directional and can be focused on a specific target.
One of the links from previous posts on this matter leads to an example of a home made HERF gun. The video clips demonstrating the use of the gun against a PC from a distance of 4.5 meters are specially entertaining.
New tool for collaborative filtering
A new collaborative filtering tool aimed at rating news from RSS feeds has arrived: AmphetaRate.
AmphetaRate is a centralized ratings/recommendation service that provides personalized news and blog recommendations through a news aggregator interface. Using compatible aggregators, you can rate articles found in your subscribed feeds to discover unread articles that suit your taste, thus filling your news addiction.
They provide an API and I hope Bloglines implements this functionality soon.
