		<description>Hmm. I&#039;m not entirely convinced by this. I agree that the transmission from (say) CW spark transmissions to AM international short-wave to FM local radio to cellular/wifi networks has decentralized transmitters and whitened the emitted spectra, but white spectra - noise - are exactly what radio astronomers spend our lives looking for. Even spectral line work looks at noise, it&#039;s just narrow-band noise. What&#039;s more, the move to higher frequencies makes the radio more able to pass out through the ionosphere, and lowers the background (typical Galactic radio background falls off like the square of the frequency). If we have moved from a handful of megawatt transmitters to hundreds of thousands of ten-watt cell phone base station transmitters (or millions of 2-watt GSM phones), that&#039;s potentially an easier signal to pick out in spite of being more broadband. And in fact, there have been proposals to find exoplanets using radio astronomy (though by looking for analogues of the Earth&#039;s auroral kilometric radiation or Jupiter&#039;s radio emission). 

So I&#039;ll grant that it might be much harder to recognize the stray signals of an intelligent civilization with today&#039;s technology than that of fifty years ago, but I&#039;m not sure it&#039;s any harder to detect that there&#039;s *something* there. The SETI folks looking for narrow-band birdies might be in trouble, though.</description>

		<description>Some of these ideas have been seen elsewhere -- primarily that the window of time during which a civilization communicates by radio is very narrow.  Other points include the fact that we&#039;re rapidly switching to fiber and other technologies that don&#039;t radiate at all.

Your point that any sufficiently advanced technology is indistinguishable from white noise is one I hadn&#039;t seen before, but makes a lot of sense.

It seems that the only way SETI is going to find other civilizations is if they&#039;re deliberately transmitting a signal that&#039;s intended to be detected.  This plotline was used in &quot;The Listeners&quot; by James Gunn, and later in Sagan&#039;s &quot;Contact&quot;.

Then of course, there&#039;s Stanislaw Lem&#039;s &quot;Star Diaries&quot; where the great philosopher Master O comes up with his own method of finding other civilizations:  The &quot;A Priori Clue&quot;, in which you look for new stars in the sky, which indicate a civilization that has discovered nuclear power and just blown itself up.</description>

		<description>Bill&#039;s been quiet for a while.  Longer even that you Jas.  The game looks like dominoes at the minute!  I&#039;m watching, agog, whilst tracking sideways into something completely different.  Should I be accused of schaudenfreud?  If I&#039;m not getting pleasure from this &#039;worst downturn in living memory&#039; (just like that last one, and the one before that -- like &#039;the hottest March since records began&#039;) and just say it&#039;s &#039;amazing&#039;, am I bad?</description>

		<description>Every summer I see people out on their bikes in shorts, t-shirts and trainers and there&#039;s me wearing all the protective gear on my bike!  I reckon they are idiots and obviously have very little regard for their personal safety.

I do, hence the full gear every time I go out on my bike. 

I was thinking of printing off some photos of people who lost their skin on the tarmac from the interweb, and leaving them tucked in the seats of bikes who&#039;s riders are dressed inappropriatly!</description>

		<description>Article 16 of the Universal Declaration of Human Rights says:

      (1) Men and women of full age, without any limitation due to race, nationality or religion, have the right to marry and to found a family. They are entitled to equal rights as to marriage, during marriage and at its dissolution.

      (2) Marriage shall be entered into only with the free and full consent of the intending spouses.

      (3) The family is the natural and fundamental group unit of society and is entitled to protection by society and the State.

----------------------------------------

It is stated as a fundamental human right to marry and start a family.  No exclusions.  It seems that California is in breach of the UN Declaration of Human Rights.</description>

		<description>Hey ElectronPusher.  Love your blog.

Something I&#039;ve read recently that your post reminds me of: A book called &#039;Don&#039;t think of an Elephant&#039; by George Lakoff where he spotlights things like Proposition 8 as a thin edge of the wedge.  How dare a government tell us who we can and can&#039;t marry?  As Lakoff points out, this is scary and unacceptable.  If we accept this it&#039;s just a simple progression to governments telling us who we can and can&#039;t associate with (think Nazi Germany), or telling us which religion we may or may not be, etc.</description>

		<description>I had a guy realize on a dual-lane highway that, even though he was in the left lane, he need to take the right exit NOW even though my Kawasaki ZZR and I were in the right lane next to him.  He just swerved violently, hit me sent me and my bike flying and miraculously we stayed upright.  For as long as there are idiots on the road I&#039;ll wear the best protective gear I can buy.</description>
