Actually, the idea behind operator overloading is to reduce confusion. Sure, it can be misused, but that's a programmer error. Dereferencing pointers is a good example of increased clarity. Code of the form obj->next()->more_next()->deeper_into_the_list(); is very self explanatory. (as an aside, I'd...

That kind of thing worried me until I realized that they can already do those things. Not easily, but just as effectively and with fewer people knowing. "There was a huge power drop from SPS01, and a crowd of protestors suddenly burst into flame." is a bit more obvious than, "A crazed protestor caus...

And come on, the reprap is just fun to play with. If it's useful, great, if not, so what? This is a hobby for most of us, no reason not to mix it up a bit.

Ram Accelerators Estimated $600/kg I've had some email correspondence with that research group, and I think the concept is sound. The problem is simply volume of cargo to get a reasonable return on investment, and a SSP program would solve that in an instant. Same with the launch loop, even if that...

I don't think I agree with you, Helius.
I'm only guessing, but I think that as long as the pistons are arranged symmetrically, you could replace a few with instrument ports. And if you're talking about measuring at the core, well, Polywells suffer the same problems.

I like them. Nothing I've read seems particularly unworkable, they have done experiments and are attempting to be peer reviewed.

That said, if they were anywhere but Canada, I'd suggest they try and get a few grants for some kind of modern art.

I'm sure Tesla would be laughed at by today's electrical engineers. Just like Nebel or Bussard might well be laughed at by plasma physicists in a hundred years. The Wardenclyffe tower was never completed due to financial reasons, though. Every version of that history I've read points to the money ru...

As I understand it, if you built a wire mesh rectenna over a couple of kilometers, you wouldn't cook very many birds at all, with an efficiency of about 60%. Not perfect, but I think it's the best idea so far.

On the other hand, it might be very useful inside the engine. I wonder what the temperature effects are on the material?

But the police (even the judges) aren't always worthy of trust. Anyway, Simon, were you using the proxy when you got the no content voice? Sorry about that, people. I just didn't realize that the crazy geographic restrictions worked in the Canada -> US direction too. I've always understood them to b...

That's a new one. Normally It's the other way around, and I've got to use a proxy to get US content. Oh well. To get that video in the US (if you actually care to do it) Use a Codeen planetlab proxy. 142.150.3.78 port 3128 for a proxy out of the University of Toronto. To set up a proxy in Firefox, g...

Possibly not the right place for this, but I thought of it and wanted to share.
People get far to wound up over politics and such. Here's a little somthing:

The canadian perspective, so maybe you won't see the humor in everything. Still, this is how politics should be treated.

Heh. In school, they always use the terms 'melting pot' and 'cultural mosaic.' I think I like 'salad bowl' better. We don't want to break up everybody's culture. Sure, it makes the country about as cohesive as a ball of mud, but we get along. It's not 'not working.' Just not working well. And in the...
