The First Person Ever To Die In a Tesla Is a Guy Who Stole One

bbn Re:Well out running the police ... (443 comments)

There was a passenger in the Tesla. He didn't get thrown out and walked away from the accident. Unburned.

The First Person Ever To Die In a Tesla Is a Guy Who Stole One

bbn Re:Remote Kill Switch. (443 comments)

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.

Airbus Patents Windowless Cockpit That Would Increase Pilots' Field of View

bbn Re:Power? We dont need no stink'n power! (468 comments)

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.

Airbus Patents Windowless Cockpit That Would Increase Pilots' Field of View

bbn Re: Failsafe? (468 comments)

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:

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.

NASA Approves Production of Most Powerful Rocket Ever

bbn Re: i dont see a problem here (146 comments)

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.

NASA Approves Production of Most Powerful Rocket Ever

bbn Re: i dont see a problem here (146 comments)

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.

NASA Approves Production of Most Powerful Rocket Ever

bbn Re: i dont see a problem here (146 comments)

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 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.

top Do We Really Need Another JavaScript Framework?

bbn Re:Do we need HTML+Javascript at all? (104 comments)

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:

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.

Microsoft Runs Out of US Address Space For Azure, Taps Its Global IPv4 Stock

bbn Re:IP numbers are terrible (250 comments)

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.

Latin America Exhausts IPv4 Addresses

bbn Re:Sometimes I wonder about half-assing it... (197 comments)

An actual example of an IPV6 address is as follows:


That is not an actual example of an IPv6 address. Lets try with some real examples instead: has IPv6 address 2a00:1450:4005:801::1007 has IPv6 address 2a00:1450:400f:803::1016 has IPv6 address 2a03:2880:2110:df07:face:b00c::1 has IPv6 address 2001:500:4:13::124 has IPv6 address 2001:500:4:13::125 has IPv6 address 2001:67c:2e8:22::c100:68b 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 /48 prefix, which is just 16 bits more than your IPv4. It is literally just an area code more (two bytes). What happens with the last 80 bits is up to you. You can make them all zero if you want to. And since all zero can be shortened to "::" that all just goes away.

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.

SpaceX Cargo Capsule Leaves Space Station For Home

bbn Re:Some calculations (56 comments)

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.

Tesla's Fight With Car Dealers Could Help Decide the Next Presidential Election

bbn Re:Bait and Switch (282 comments)

Because it is unlikely to be true. Anyone can go to the Tesla website and check the prices. You will get the car at the price listed on the site, no more and no less.

If he is talking about financing, nothing forces you to finance the car through Tesla. In my part of the world one usually borrows the money in a bank and this is how it is done when buying from a dealer too.

If the power is out for 3 to 4 days you have no food, no water, no gasoline, no heat. The phone service is the least of your worries.

Truth is that people today have a much better chance of getting emergency services with their cell phones.

Ask Slashdot: Legal Advice Or Loopholes Needed For Manned Space Program

bbn Re:Trouble Ahead (201 comments)

So, if you launch your spacecraft and it blows up raining debris down on my house - your home nation is clearly responsible under Article VII.

That does not mean that Denmark will pay you any damage on your house. It means you get to sue me under danish law. The danish citizen (me) will then pay you the damages, if so determined by the danish judge.

All the other speculation such as a $100 million USD bounds has no basis in danish law and so will not be required. If I can't pay you, that too will play out accordingly to danish laws. Most likely that means it is just too bad for you. You wont be getting anything from the danish government either way.

It is the only way a civilized country can act - by following the laws by that country. A country is not a person that you can say "they owe me because the treaty says they are responsible" - you are only owed money if the laws of the country concur. And let me tell you right ahead, there are no laws in Denmark to the effect that government will step in and pay damages on behalf of a citizen if said citizen is unable to pay. And neither is there any such law in the US to my knowledge. If a SpaceX rocket drops on my car, I get to sue SpaceX in an american court for a new car.
