I think someone here has it in his sig: "slashdot is unusable without NoScript"

Better tyres yes, spiked tyres depends.
They make sense in areas/countries with low population density and snow covered roads.
On mostly ice/snow free streets they wear down any pavement quite fast, resulting in street repair costs magnitudes higher than the initial savings during winter.
That and they are really shitty compared to normal tyres when you brake.

I'm deeply impressed how you managed to get your post as a written letter delivered to slashdot via snail-mail. and have them type it in for you ;)

Well, the British are famous for some pronunciations too, especially when it comes to town names.
Just look at the nice little town of Littlelancfordupstratdoushire, pronounced "oi".

Best "profit" reply ever!

Don't program what they say, but what they mean.

You see, in English language basically everything that can't run away and hide up on a tree on its own is considered female.
And this thing is even flying towards us, which qualifies double, especially for slashdotters.

Easy solution. Just prepare a spaceship with a catwalk, and use some of the already anorexic wannabe fashion models as astronauts, promising them they'll get themselves as cover on Vanity (or whatever).
By the time they are nearing C, their mass will be zero.
Problem solved.

If you manage to carry propellant several times the mass of the sun with your spaceship, yes.
Good luck.

Since none of the articles explains technical details, I can only speculate about the dolphins (which is more interesting anyway).
If their second "click" is used as a reference signal, i.e., the signal itself, not its echo, it could be used not only to invert the first signal and filter out the noise, but also give information about the distance:
Depending on when the reflected echo comes in - delayed (and overlaid) - to the reference (second) signal it would also account for the distance of the target.

Meanwhile I've read all linked articles, and none of them describes how it actually works, which was GP's question.
Quoting an absolute meaningless part of TFA doesn't help either.

Or the signal cancels out the dolphins. Whatever.

Well, the summary describes it:
The radar "sends out two pulses in quick succession to cancel out background noise", like dolphins which "send out two pulses in quick succession to cancel out background noise".

I also think that sending out two pulses in quick succession may cancel out background noise.

I can't believe no one came up with this yet:

One ring to rule them all...

Louis Armstrong! He even wrote a song about it.
