Not really.

Security is not an all-or-nothing proposition. In the real world, an adversary will NOT attempt to crack your encrypted filesystem. Instead they will do one of a hundred other attacks, like swapping your laptop with one that has a cloned disk and hardware but an embedded keylogger, or add in a shim between the disk and interface, or install an infected MBR that logs the decryption password, or perform a RAM sniffing attack to steal the keys, or simply extort the keys out of you.

Security is a process of analyzing the most common risks, and determining the best way to deal with them. Sometimes this means determining that a particular security action will lower your security by attracting the attention of entities with far more sophistication than you are prepared to deal with; if you are worried about criminals stealing your laptop, and your mitigation ends up attracting the attention of the NSA, you have lost the security battle.

IDS / antivirus have no ability whatsoever to detect a hardware keylogger, by the way. If you attract the attention of someone who can gain physical access to your hardware, you lose-- period.

AFAIK it gets revisions with every major release. Like the EXT family its backwards compatible, transparently.

What big features is it missing aside from the checksumming / self-healing stuff thats already in ReFS? Feature wise its a pretty decent FS; its biggest flaw AFAICT is its bad performance in directories with huge numbers of files.

So you are trying to tell us that they not only recorded this thing that occurred in "the span of a millisecond" but they also understood and were able to take actions on it while it was still going on? I don't buy it, any more than I buy that the previous millisecond events were recorded after they arrived at the Earth rather than when they arrived at Earth.

Congratulations on this being the first time that the arriving radio waves were captured in real time. But I would be far more interested in hearing how you capture radio waves other than in real time. I wouldn't even need a DVR if I could do that.

My guess is he consulted any number of alchemy texts trying to figure out how to transmute gold.

Even in modern countries there are holes. I live in Iceland and we have one of the best rates of broadband connectivity and fiber deployment in the world. But my land is in a sparsely populated valley so it hasn't paid off to run a line out there, most people just use their cell phones for a net connection. If satellite could beat that (and wouldn't be too blocked by mountains), even in highly connected countries there's a real potential market here.

Heck, there's a lot of people who would get it if the price and stats were right even if they had ground-based broadband. Everyone here has bandwidth caps on international net traffic, only domestic is unlimited. So people who want to do a lot of downloads of foreign content might well choose that instead of or inaddition to regular broadband.

If technology had jumped directly from the 1979 Impala to the 2014 Honda Accord, yes, that would have been really f*ing amazing and a huge technological innovation, and the company that did it worthy of every bit of praise thrown at it for doing so.

Yeah, I had written a section about this but must have messed up my tags and Slashdot ate it.. Delta clipper highest achieved altitude: 1 kilometer. Falcon 9 first stage alone highest achieved altitude: 130km. Delta clipper furthest flown from the landing pad before landing: 300 meters. Falcon 9 first stage alone, furthest flown from the landing pad before landing: 300km. Delta clipper mass ratio, 2,5. Falcon 9 first stage alone, mass ratio 20 (and the boosters on the Falcon Heavy have a mass ratio of 30). And on and on and on. Not to mention that they're built utterly differently.

Aww, Slashdot ate my whole paragraph comparing Falcon 9 to the Delta Clipper, that was the best one.... must have messed up my tagging :(

Internet satellite thingy - almost identical to Teledesic

Teledesic: Launched on Pegasus rockets which cost your firstborn child. SpaceX: Launched on Falcon rockets which are cheaper than the Russians and Chinese even without reuse. Teledescic: 90s computer and communications tech (this was the era where playing the original Doom game took a high end computer and nerds envied those with ISDN connections). SpaceX: 10 iterations of Moore's Law later. Teledescic: Communcation sats have to be large objects with heavy hydrazine thrusters for stationkeeping. SpaceX: Much smaller satellites available (all the way down to cubesats), with a wide variety of ion thrusters for stationkeeping available.

Yeah, totally the same situation.

Hyperloop - first theorised by Robert Goddard nearly a century ago and a staple of SF for decades

Goddard and sci-fi: vaccuum tube. Hyperloop: tube full of thin air. Goddard and sci-fi: maglev. Hyperloop: ground-effect aerofoils. Compressor on each craft. Goddard and sci-fi: massive trains holding huge numbers of passengers. Hyperloop: small computer-timed trains to spread out the load on the track and thus reduce construction costs. Goddard and sci-fi: Trains implausibly deep underground. Hyperloop: built like a monorail. Goddard and sci-fi: tubes take the shortest route to their destination. Hyperloop: Trains go primarily over already-built and permitted infrastructure to reduce right of way and environmental costs / challenges.

Yeah, totally the same situation.

Falcon 9 - It can land vertically, like errr, the lunar module or the Delta Clipper

Tesla - Okay, they're quite nice but electric cars aren't exactly a new idea

Aww, you didn't give me an example to compare it to! Let's just go with the EV-1, since that was probably the most modern commercially-produced EV before Tesla EV-1, range 60 miles (older version) to 100 miles (newer version). Tesla Roadster, range 230 miles, and Model S, up to 300. EV-1, 0-60=8 seconds. Tesla Roadster and Model S Performance, 4 seconds. EV-1 production: about 1100. Tesla: produces that many cars in *1 1/2 weeks*. EV-1: Loved by owners but panned by critics. Tesla Model S: not only loved by owners but has been getting some of the highest ratings for any kind of car period.

Your "analogies" are akin to saying "So what if he won the Indy 500 - I raced my go-cart down the street the other day and beat a soap-box racer!"

Cuba is NOT about to make any big changes. At least not unless the man who has been busy trying to destroy this country by Executive Action decides to prop up the Communist Government at our expense. The idea that Cuba has been suffering from an isolationist policy imposed by the United States is bogus. We were (somewhat) cut off from Cuba by our government, but we are only one country. Canada and most of the rest of the world has still been trading with them. Sure, Cubans drive around old American cars from the 50's, but they keep them running and keep fueling them with imported gasoline. Other countries would be glad to sell them newer cars, it is just that when you have a communist mindset keeping the economy depressed, no one has the money to buy new modern expensive cars.

Sure, they might sell Americans some cigars, although there has been a supply of them coming in through Canada already. They will not be selling us sugar, but not because of any real barrier. Rather because of a completely artificial barrier, Cubans who moved to Florida when Castro took power have gotten laws in place that impose such high tariffs on imported sugar that we can't import it, and we have higher prices on Sugar than the rest of the world, with all of that money going into the pockets of a few politically powerful Cubans in America who grow sugar and trickling down to the politicians they buy to keep the system in place.

Cuba is going to see a little bump in tourism, at least while the novelty is still there, but it will not be that much or make a big impact, they already have tourism from the rest of the world and from Americans going there through Canada who show their American passports and ask that they not be stamped to avoid problems back home. We will still over pay for sugar compared to the rest of the world and have tariffs that keep us from importing it from Cuba.

If people in other countries have and put up with corrupt governments, and go out and kill and eat "bush meat" and get Ebola, that's too bad but we have our own corrupt politicians here, I don't see how we can take on correcting theirs when we can even correct ours. And we have the flu virus in this country, and even with our first world hospitals and our Obama-care the flu is killing more people in America than Ebola is killing in the entire world. Yet I don't see Obama sending the Army to help out when one of my friends gets the flu. Perhaps we should realize that we are no longer the largest economy in the world (China is, although I think we still give them "foreign aid", and do that with money that Obama borrows from China!) and start trying to solve some of our own problems rather than playing World Doctor and World Cop and World Missionary and World Peacekeeper.

"Cruising speed" is otherwise known as "terminal velocity" and is hundreds of meters per second. And I'll reiterate: the *point* is to go slow. Drag is a *good thing* on the way back down.

Other corrections: It's false that there's no part of the rocket that reliably faces a given angle - it doesn't tumble, it maintains an orientation generally between 0 and 15 degrees relative to the direction of travel. And the concept that bloody air is going to kill a pneumatic piston in a matter of minutes is the height of absurdity. .

Apart from actually launching a rocket to space and then having it descend and attempt to land, what's your proposed method to determine how much the fins have to move during a real-world descent and thus how much hydraulic fluid they'll consume? (beyond the simulations, which SpaceX uses extensively; they're invaluable but don't correspond 100% to real-world flight scenarios)

Yeah, it's kind of funny, but with this "failure" SpaceX will still end up recovering more of their first stage than is recovered for 99% of first stages launched in the history of man. Not like any of it will likely be of any use except for analysis and then scrap, but still...
