Most of the time the green background behind the comment titles is missing on Safari 3.2.3. And yes I do realise that using the OS bundled browser to read Slashdot is Not the Done Thing, I'm just very lazy.
Yes they do. Travelling on motorways in the cab of an HGV at 56mph is a surreal experience. Everything happens very slowly. If an empty, powerful truck finds itself behind a weak, full truck going up hill it'll still overtake so 2 of the 3 motorway lanes become slow lanes. You do find them overtaking each other on the flat, usually because one limiter is set slightly higher than another.
How banning pointless encryption of signals? Encrypting the signal in the Bluray player then decrypting in the TV is a complete waste of power, why not just ban the use of HDCP?
But in a transformer the coils are very close to each other, and are wrapped around the same lump of iron. With the devices the coils and cores are separate. Magnetic fields decay exponentially so even a small gap will reduce the transmitted power by a fair bit. There seems to be various proposed methods to get around this problem, but none of them seem to be significantly better than the others.
Interesting point about electronics reducing the idle currents, as this would be another issue.
It seems that more and more mathematicians are using a new, high level language named "research student".
