Said kill switch could just limit engine power, tell the driver to stop safely before bringing engine power down to zero in steps. Basically what happens if you run out of fuel (charge). People usually do not get hurt from that.
Nobody knows what strongly typed means: http://en.wikipedia.org/wiki/S...
But if you are completely without power, say the RAT has failed or you had a fire that destroyed the wiring, then you will crash. There is no way for a human to control those beasts by muscle power alone, even for those planes that are not fly by wire.
The worse thing that could happen to a view screen is that it gets so smashed up you can't resolve fine details through all the cracks (actually, the absolutely worse thing that could happen is that it ceases to exist, but at that point you've got other problems). But the fine details are hardly necessary for flying and landing.
Not so, This 747 went through a ash cloud from a vulcano and got their windscreen sandblasted: http://en.wikipedia.org/wiki/B...
As Flight 9 approached Jakarta, the crew found it difficult to see anything through the windscreen, and made the approach almost entirely on instruments, despite reports of good visibility. The crew decided to fly the Instrument Landing System (ILS); however, the vertical guidance system was inoperative, so they were forced to fly with only the lateral guidance as the first officer monitored the airport's Distance Measuring Equipment (DME). He then called out how high they should be at each DME step along the final approach to the runway, creating a virtual glide slope for them to follow. It was, in Moody's words, "a bit like negotiating one's way up a badger's arse."[1] Although the runway lights could be made out through a small strip of the windscreen, the landing lights on the aircraft seemed to be inoperable. After landing, the flight crew found it impossible to taxi, due to glare from apron floodlights which made the already sandblasted windscreen opaque.
As you see, they didn't eject. They landed the plane flying blind.
Next year is much sooner than SLS.
The main reason that Falcon 9 Heavy is delayed is said to be that they are sold out on stages. They can't produce them fast enough to spare some to test the heavy.
This SLS will not bring 130 ton to LEO. They are just working on the small version, that will not do much more than Falcon 9 Heavy (53 tons vs 70 tons for SLS).
The SLS project will be cancelled long before they manage to test the 130 ton version.
SpaceX already has Falcon 9 Heavy which will do most of what NASA wants to do with SLS. In addition SpaceX is developing the Mars Colonial Transporter http://en.wikipedia.org/wiki/M... which will put 100 tons of cargo on Mars. In comparison the SLS will only put 100 tons in low earth orbit.
Oh and the Mars Colonial Transporter will be reusable.
You like C#, I like Scala and the next guy over likes Haskell. Trying to force everyone to use one language that fits all is one of the big fails of JavaScript.
Language development is an ongoing research area. You can not just freeze time and say we will use this one for the rest of time.
This is why we now have a host of languages that compiles to JavaScript. I use Scala-JS that will convert my Scala to JavaScript. But this is horrible inefficient and limiting.
The correct solution is PNaCl: http://en.wikipedia.org/wiki/G...
Portable Native Client is a LLVM based byte code language, that is designed to be a target for other programming languages. You can compile your beloved C# to PNaCl, someone can compile his C++ and I can compile my Scala. And it is almost as fast as if you used machine code as target.
That and the fact that you have people who forget to remove the nozzle before leaving the gas station. How many of these people will a supercharging station fry?
None. An electric car will not move while still plugged in.
in gp example it would be:
there's tons of better ways then having to memorize 8 groupings of 4 letters.
The last one is already legal syntax:

Nothing stops you from assigning fe80::1 to your printer #1 and so forth. Or you can use ULA to the same effect: fd00::1 to the first printer etc.
Or do it the sane way and use your prefix::1.
You do not have to use MAC based addresses you know. You can just assign the addresses manually (static) or you can use a DHCPv6 server.
You do realize that a 32 bit computer will easily do 64 bit math?
An actual example of an IPV6 address is as follows:
2001:0db8:85a3:0000:0000:8a2e:0370:7334
That is not an actual example of an IPv6 address. Lets try with some real examples instead:
google.com has IPv6 address 2a00:1450:4005:801::1007
gmail.com has IPv6 address 2a00:1450:400f:803::1016
facebook.com has IPv6 address 2a03:2880:2110:df07:face:b00c::1
arin.net has IPv6 address 2001:500:4:13::124
arin.net has IPv6 address 2001:500:4:13::125
ripe.net has IPv6 address 2001:67c:2e8:22::c100:68b
gigabit.dk has IPv6 address 2a00:7660:0:50::2
The last one is my own website. Your IPv6 address is as long as you want it to be. Many ISPs will assign you a
As to those first 48 bits there is a system in it, which makes it easier to remember. Notice how all of the above has either 2001 or 2a0x as the first block? Also the second block is the ISP and most people only deal with a few of those. So you will quickly memorize that. The third block is basically your customer id within the ISP. And everything after that is yours to decide.
It is true that if you go with auto configuration addresses on your computer, you will get horrible long addresses. But if you are doing that, you are not the kind of person to deal with IP addresses. Personally I let my computer choose any long address it want, but for my servers I am picking something sane.
The space shuttle was $450 million per mission not including development costs. That would lift 24 ton and a lot of volume to ISS. That was good for building the space station but perhaps overkill for the maintenance. They are not even using the full capability of the Dragon spacecraft.
The Dragon will only move 3.3 ton to the ISS. If you only count weight by dollar this is more expensive than a Space Shuttle launch. On the other hand you will get much more frequent deliveries which may be what is needed now.
If you count development costs, each Space Shuttle launch was 1.5 billion USD. Viewed this way, the CRS program for Space X is just one shuttle. And perhaps this is the correct way to do the accounting considering that the 1.6 billion that Space X receives also has to cover their development costs. I would expect that they can give a good discount on future launches, should NASA want more than 12.
We are not a clone.
