    I remember seeing a four legged running robot on Nova. It to a VAX to control it. At the time I thought "well that is useless it takes a freaking VAX". Well now that I have the power of many VAXen in my cell phone it doesn't seem that bad of an idea at all.
    We have so much computing power in our hands that things like this are getting much easier. Of course I do not think we will ever see Mechs for the simple reason that a tank is a much smaller target and can probably be better armored.

    Pascal was my first programing language. I learned Basic after Pascal. Of course I was lucky enough to have used the good old Commodore SuperPET which came with Interpreted Pascal, FORTRAN, COBOL, APL, and BASIC. We didn't really get into the FORTRAN or COBOL but I did play with APL which at the time was really cool. Frankly I would say that the SuperPET was the best computer for learning about programing available around 1982. We even had a primitive network that allowed us to share drives. I would love to find the manual for the MUPPET yes that is what the sharing device was called that we used.

Eclipse.org and Netbeans are great free IDEs that you can download. I would also suggest Squeak. If you are on the mac Objective C is available but may be a bit much for people just getting started.

    Truth is that back in the C-64,Apple II, TRS-80, 99/4a, Atari 800/400, Coco, and Sinclair days we all used Basic because that is what we had. Some times you could find an Assembler or believe it or not a machine language monitor but real programing languages where expensive and hard to come by. I was so excited when a friend gave me a copy of COMAL. Now you can get just about any language you want.

    What? Are you still living with the 4th grade idea that the high pressure area under the wing pushes the wing up in to the low pressure area caused by the curve of the wing? Ahh no. All heavier than air craft fly by pushing air "on in the case of a rocket gas" down.
    The surfaces of a wing deflect air down that is how they fly. Same as a prop except that it deflects it back. Same as rotor. They are all in effect wings, even the blades on most fans. That whole Bernoulli effect is just a pleasant fiction and really isn't how wings, props, or rotors work at all. If you want proof just pick up any cheap balsa glider and check out the wing. They are rectangular in cross section but they still fly.
    It is a real shame how many people are actually learn that whole curved top flat bottom crap in school and believe it. It is both a classic case of terrible science education and really bad thinking skills. Just one look at a cheap balsa glider or even the sight of a plane flying inverted should cause people to go huh?????

    Would you like "big complicated fan"? They are blades that spin and move air. Yes they can change pitch but then so can a lot of propellers. They can do have cyclic and well as collective pitch control which does is a difference and they often have hinges as well to help with the retreating blade issue but a lot of them are now called ridged but in effect they are really just fans at the simplest level. And there is very little difference between the "tail" rotor and any other prop except that it is used to counter the main rotor.
    Frankly to go into all the complexities and dynamics of a helicopter is just a bit too long of a subject for a Slashdot post.
    The prop of a plane and the rotor of a helicopter are at their heart fans for moving air.

    b A rotor and a propeller are much the same thing. The rotor on a helicopter is a little bit more complex because it also acts like a wing. That is why the are also called rotary wing aircraft but really they are a big fan just like a prop. As to it being the norm not really but now that the V-22 is in service is isn't a crazy stunt anymore. And as to efficient this lift device also is not very efficient just take a look at the specs on the helicopter I included that can carry much more weight with less than half the power.
    c. Even that is a very iffy use case. The problem with thrusting down on the ship is the danger to the crew. You will still need to secure the craft and with it thrusting that sound very risky. The other issue is how fast can you reverse the thrust? If it takes even on second you could be in a very bad spot as you go from hover to down thrust in a storm. The current solution is I think is called bear trap in Canada or RAST in the US. The helicopter hovers well above the ship. They drop a line that is then attached to a winch. The helicopter goes to full up thrust and they just crank it down. The real issue with landing at sea in bad weather isn't really staying on the deck but that fact that the deck is moving. The cable method means that the helicopter moves with the deck and when it is on the deck it is already secured to the deck. The reverse thrust is a solution in search of a problem unless you really want to go down fast.
    Now what this would be cool for is maybe a drone flying in a city or forest. Places where a large rotor would be to restrictive. But the hype was..... Well makes this worthy of being called trash.

But you can see how easy it is since we started off with "I will just use someone else's wifi" to now using several proxies. So what makes you think that they have not comprised those proxies with a man in the middle attack? Do you honestly think that any security organisation with access to the telecom infrastructures allows open proxies that are not monitored? I mean do you honestly think that they are not on every IRC channel and board and have access to the same list of proxies as the hacker community does? They just ignore most of the traffic because it isn't a threat to nation security. Now that they have made threats things may have changed. The only why really to avoid getting caught is to stay below the radar and not get their attention. None of this is magic just the way it is in the intelligence community. They tech they have is amazing as is the tallent and that is a good thing IMHO.

    So you are saying that they are like a wing of a plane. We all know that planes can not fly inverted correct? And that maneuvers like an outside loop are impossible.

    Actually helicopter rotors tend to use symmetrical airfoils. What stops them from trusting upwards is that the blades flex and would hit the structure of the helicopter. Plus there really is almost no need to ever thrust down. Just setting the rotor to zero pitch would be good enough but the tend to want to keep a little lift on the rotors on landing just to keep them for bouncing around and being a danger.

    b. Propeller engines can't hover? What? I guess you have never seen a helicopter? Or any 3d model aircraft? Or ever been to an air show and seen a and Extra hang on it's prop? With a high enough power to weight ratio yes they can and do. And of course the V-22 Osprey does it on a regular basis.
    c. Trusting up? Talk about being of very limited value. Just going to zero lift on landing is usually good enough. Using engine power to pin the craft to the ground has very limited utility.

    Over all this is mildly interesting and could be really good for drones that need to fly in areas too tight for rotors. The claims of high lift and other claims are really out there. The performance is rather unspectacular. Here is a home built aircraft you can buy that has less then half the HP and carries a much bigger payload. http://www.innovator.mosquito.net.nz/mbbs2/specs.asp
