RichRMA: Depressing. The Americans frittered away their money on the white elephant known as the ISS, killed the Shuttle program, and now have to go begging to the Russians to launch their people TO the white elephant while what's left of NASA hooks its wagon to the global warming gravy train to save what jobs they can. How did it get to this?
The Shuttle program lasted nearly 30 years, maybe it was near its planned length. The main problem is that it was not possible to use this ships as often as initially planned, and it became more and more expensive to launch and mantain the aging fleet.
I don't believe the ISS is a waste of money, Soviets first and then Russians showed that space stations are needed also to be able to plan for future trips to remote destinations (Mars, to begin). A space station is needed and it is better to share a common program, that having several national programs competing with each other.
It was a smart move from NASA to join a program with experienced partners, without having to develop everything from scratch, being some 20 years behind...
I guess this is because the sidewalk is a lane for walking/cycling, that is interrupted when crossing normal or private road, so for every crossing, you have an "end of lane" sign, followed by a new "begin of lane" sign after the crossing.
I'm not saying this is smart, just how is it possible to have something like that :-)
This new version seems to me better than 4.0, in terms of performance, on a PC that was very, very slow on 4.0. I can see the difference, maybe as it was too slow with the previous version. Maybe not as fast as with 3.6, but while with 4.0 I was already planning an HW upgrade, now I have some time to make a reasonable choice, not being in a hurry like before...
