The problem with NetStumbler is that while it's easy to use, it isn't comprehensive. It doesn't capture the raw signals from access-points, but instead relies upon the underlying operating system (Windows) to do the work for it. A lot of information is lost in the process. In order to comprehensively map access-points, you need to capture the raw wifi signals and packets, such as through a "packet-sniffer".
They seem to be claiming that you need a packet sniffer to bypass the operating system. They give the example of how it works in Windows, which I doubt google are using. In practice they would most likely run linux with a hacked wifi card driver which captures the information they want in the way they want.
I recall President Obama saying that the withdrawal would be done safely. It should be obvious that every US person in Iraq can't just jump on a plane on the same day and fly home to safety. Its going to have to be done in the right way and maybe that way will take longer than 16 months.
There was a Democrat in my district who tried to vote against healthcare, against the stimulus bill, and so on to appease the increasingly anti-government voters. We didn't buy his sudden change. He lost.
So, now you've got a Republican in office. How does that make things better?
We did have one of them once and we may yet see him in Government.
cut-rate '70's era NASA space station that was built out of Atlas rocket part
Not disagreeing with you but skylab was the best US space station. Look at how long it took to get the ISS working properly. Of course skylab had the advantage of pre-dating the shuttle.
By your definition I don't believe we are intelligent. Intelligence (and sentience) are made up to justify our treatment of entities we put in other categories. We used to treat black people the way we currently treat animals, and the justification was much the same.
Compare the last five minutes of the Apollo 11 landing with the lunar landing sequence in Rocketship Galileo. They had similar dramas. If anything Heinlein's crew handled operations better, while Armstrong got himself into a mess by working too much of Aldrins job.
I suppose the thing which bothers me about thermals is the rough air getting in and out. Thermals are surrounded by sink. A big, fragile aircraft could be in lift and sink at the same time and be subject to structural problems.
Do you mean that time travellers could observe us but not interact? The influence of observers on the observed seems to be pretty much embedded in quantum mechanics and (when you think about it) classical mechanics.
Of course our records are a kind of time travel (we watch old movies) and we all travel into the future.
A proper sailplane can stay airborne for ten hours or more given fairly favourable conditions. For example flying in the mountains with a bit of wind blowing there should be enough lift to keep you flying indefinitely.
But if its dark or the pilot is tired then the sudden death percentage rises dramatically.
No, I am building a joke around the idea. If you are interested John Varley did this with his novel Millennium. It started with a great tightly written time travel story Air Raid which became a really crap movie Millennium. The novel was based on the movie and Varley turned it into an essay on time travel SF. Its a lot of fun including a bit where the time travellers need to fake the cockpit voice recording of a crashed airliner so they tape the replay session and...
I had a peek at TFA so I could comment. This thing would fall apart in a thermal. Ridge lift means flying fast to avoid flying into the rotor behind the hill. Its not uncommon to pull a couple of Gs flying into and out of a thermal and this aircraft doesn't look up to it to me.
My guess is they are waiting for still air before they fly it. Look at the size of those control surfaces. Sure it will have a high LD but at 30 knots or so.
If we are going to get time travel out of it we would already be neck deep in time travelers and it would be impossible to get tickets to the world cup. Neither of those things is happening so this result will not give us time travel.
Parameterized SQL, or prepared statements, completely prevent SQL injection attacks. They might also speed things up in some circumstances. Why not simply use them exclusively?
I question the need for SQL. Can't we have a simple OO query system? We don't need to write strings of TCL to interact with GUI components.
I'd argue that the GP's mere mention of escape velocity is pretty unreasonable. Nobody even expects a lander craft to reach escape velocity, it only needs to re-orbit itself and dock with another stage. Then that can reach escape velocity. This is how the Apollo missions worked, and how the planned Soviet missions would have worked.
I said "2km/s" for lunar escape velocity as an indicative estimate. I wasn't trying to be precise.
The discussion was about finding "stepping stones" for a trip to Mars. That term could mean a number of things. It could refer to the need for systems integration after components are launched. It could refer to the need to take on consumables after launch.
If the intention is to do systems integration on the surface of the moon then you need to add the delta-V for a flight down to the lunar surface and up from the lunar surface again. This velocity change is twice the escape velocity. 2.38 * 2 = 4.76 km/s which is a significant velocity change.
So you would want to have good reasons to do integration on the lunar surface. If you do it there you will find other hazards. It gets very cold at night on the moon. Hardware designed for full time exposure to the sun won't work correctly. Lunar dust tends to attach itself to equipment.
It may be possible to use lunar resources but right now we don't know how hard that is going to be. The water we know exists at the lunar poles might be very hard to extract. What if it exists as one millionth the bulk mass of normal regolith? How do you extract it? No equipment exists for working on the very cold places where ice is believed to be found, so new development need to be done.
In short, I don't believe the moon has much to do with a flight to Mars. Near Earth asteroids OTH might be very useful. Many of them are believed to contain more water than the Moon, and they have a negligible escape velocity.

So whats your preference? First past the post or Single transferable vote?
would have to spread their bribes over a lot more politicians and they will do whatever it takes to prevent that additional expense.
But the number of elected politicians would not increase so I don't see how this would significantly increase the number of people to be bribed.
Yes the argument reads like BS to me:

Take care with photocopiers. Don't use the one at work for example because they may leave a trail.

Then again, I've read too much Heinlein. *grin*

Jobs has particular domain skills which go beyond pure business management.

Do tell. Maybe I was led astray by watching glider pilots in the UK. They head for the nearest bit of ridge lift. Never heard of them thermaling.
A proper sailplane can stay airborne for ten hours or more given fairly favourable conditions. For example flying in the mountains with a bit of wind blowing there should be enough lift to keep you flying indefinitely.
But if its dark or the pilot is tired then the sudden death percentage rises dramatically.
I can't believe that they couldn't allow even one of those inflatable ones because of the weight...
Probably the sexual harassment issue. You can't pay just anybody to keep in inflated.

Not many in Switzerland I suspect, even in the summer.

I am sure Leonard Nimoy would agree. This is a very dangerous project.
What would be the point of that? People in the future would already know the outcome.
I am an Australian so I already know the outcome of games involving my team but that wouldn't stop me from watching the game.

Yeah but portable.

Interesting to note that the star trek crew were using pen based tablets decades before they were invented.
I don't recall seeing the UI. Usually some hot chick brings the device over to Kirk and he writes on it but I cant be sure it was a computer display.
