It would also use much less land (no runways needed), and could terminate in the middle of a city a'la Grand central station.

Unfortunately the "cost savings" Musk envisaged for the LA-SF version were in part achieved by not going anywhere near the cities it served, sitting tens of miles outside - a situation more extreme than most airports, which at least try to be close to the cities they serve.

You can probably build a pretty cheap airport "serving" LA if you build it fifty miles away too ;-)

Submission + - EPA to Attempt Destruction of Aftermarket Automotive Industry (sema.org)

drinkypoo writes: The EPA is proposing to make it illegal to convert street vehicles into race cars, and to make it illegal to sell certain automotive products used for that purpose. This has severe ramifications for the right to repair and modify other types of hardware as well, but the direct impact alone would affect the activities of millions of Americans.

Comment And they want you to trust them, too (Score 1) 59

The latest JRE updater elevates permissions before it even needs to, so the first inkling you have that something is taking place is the UAC prompt. Only after denying it did I find out that it was from the Java updater... the prompt only said "Java". I don't know about y'all, but my first impulse upon getting a mystery UAC prompt from Java is not to grant permission to rape my PC

Comment Needed to assign fault (Score 1) 349

We need the line to assign fault in a collision so that we can figure out who pays. They don't have the line in Panama (cities and Interamericano aside) and people do not slow down. They instead glide towards the edge just as you meet, unless they're drunk and then there is a collision. They do have interesting traffic laws there, though. If you hit a horse during the day, you are automatically at fault. But if you hit one at night, you're automatically not at fault...

If memory serves, and google says it does, the temperature of the sun is around 15 million K. I'm not gonna bother googling it, but I'm pretty sure 15 million K is lower (much, much lower) than absolute 0. So the numbers flat out don't work.

A. The reaction rates differ by about 16 orders of magnitude: The sun is going to run about 10 billion years with no refueling. A Tokamak fusion reactor would run for a few seconds or minutes.
2. The sun is using a completely different set of nuclear reactions with completely different fuel. There is no direct comparison anyway.

What, I think, is telling is not that they're just making these somewhat dumb comments, it's how effing angry they are, as if Cortana not putting up with simulated harassment is in some way taking something valuable away from them.

Ever since, well, just before this GG nonsense started, Slashdot's readership has been really circling the toilet. I wonder how these people have jobs given their anger issues with women.

Kinda true, kinda not. The idea was to replace CAHSR, but CAHSR is itself billed as a replacement for flying.

Personally I think the Hyperloop proposal is done in bad faith - the system Musk proposed was supposedly substantially cheaper, but only served two of the four cities joined by CAHSR, was something in the region of a hundred miles away from those two cities, couldn't carry anything like the same number of passengers, and Musk hand waved quite a bit about costs (did he really think the CAHSR people hadn't considered viaducts? And in what world does a viaduct - even for a single pipe stuck up on stilts - cost only a quarter of a million dollars a mile?) suggesting it would probably cost several times the amount Musk proposed.

And, I'll be honest, I think travel in those things will be a nightmare. But I'd expect nothing less from anyone in the car industry - these are people who have never "got" public transportation, largely because they love driving so much they can't imagine anyone else wouldn't.

Why not go all out and just evacuate the wings for maximum lift? Moron.

AFAIK the problem is if you make it big enough for the effect to be meaningful, it takes up too much space. So my question phrased more properly is, can you just stack them, or is there some property which makes that infeasible?

No, sorry, that's not true. "Your community" has no input into whether you build 300 ft structures on your 1000 ac of private property out in unincorporated land.

Why Facebook Really Shut Down Parse (medium.com) 39

New submitter isisilik writes: For those working in the 'aaS' business the Parse shutdown was the main topic of conversation this weekend. So why did Facebook decide to shut down their developer platform? The author claims that Facebook never wanted to host apps to begin with, they just wanted developers to use Facebook login. And he builds up a good case.

It's actually kinda awkward to draw any conclusions from that as adjusting for other factors isn't trivial.

Imagine, for a second, if A causes B, but only when combined with C, D or E. (And C, D, and E don't cause anything on their own, only when combined with A)

A is going to look like a cause of B, but C, D, or E will be relatively difficult to correlate with B, especially if they're common. That may result in people assuming that, say, C had nothing to do with B simply because A was present.

I know, I know, basic stats and all of that, and I doubt video games are causing (much) harm (nothing's completely harmless ;-)) but I'd be more comfortable with more studies.
