Richard Stallman Accosted For Tinfoil Hat
ndansmith writes "Bruce Perens posts in his blog about an amusing encounter between Richard Stallman and United Nations security at the World Summit on the Information Society in Tunis. It seems that RFID technology, which Stallman opposes for privacy reasons, was used in the identification badges for the conference. From the blog: 'You can't give Richard a visible RF ID strip without expecting him to protest. Richard acquired an entire roll of aluminum foil and wore his foil-shielded pass prominently.' During a keynote speech, Stallman also passed around the tinfoil for other to use as well. It seems that UN security was not amused, however, as they would not let him leave the room for some time." What makes this even funnier, of course, is that tin foil hats won't stop them.
If the holeys in a mesh are half the size of the average wavelength of the radiation, practically none will get through, assuming it is made of the right material. The proper size mesh for RFID technology is left as an excerise for the reader.
Even those who arrange and design shrubberies are under considerable economic stress at this period in history.

The UN has a huge positive effect on the world. Examples:
It strikes me that, of the people who are wholly negative of the UN, the vasty majority are from the USA. It's not surprising, given that the UN are criticising the USA for blocking their torture investigations at the moment.
I don't think you'll find anybody claiming that the UN is a perfect organisation. But only trolls and ignorant people could claim that the UN is not worth supporting.

I'm sorry, I thought it was obvious that the MIT article was a joke. Now people are quoting it as fact.
As smart as those MIT students may be they failed to explain why it amplified the signal.
Simply put, the 'tin foil' or aluminum hat they constructed was a parabolic antenna with the test subjects brain as its focal point. Go back and look at those pictures in the MIT article and see for yourself.
You can in fact shield an object if you *completly* enclose said object with aluminum foil (it's conductive). However, copper foil and screen is the standard for shielding used by professionals.
The enclosure doesn't have to be air tight. But the gaps or holes in the foil need to be smaller then the wavelength your trying to attenuate. This is why RF "screen rooms" can use copper screen instead of solid copper and still be effective to up around 3 GHz.

The U.N. general from Canada motioned to intervene. The U.S. refused. From your link:
The U.N. itself cannot do anything: It's a place for the member nations to talk. If the biggest member decides that a genocide is not worth the risk of potential military casualties, then the fault for inaction is not with the U.N. for trying, but for the member nation for refusing to act.
