Fellow Americans seem amazed when I tell them this, but Abraham Lincoln was the closest the United States of America ever had to a complete dictator. He monitored communications, he shut down state legislatures, he imprisoned Congressmen -- there were so many political prisoners at one point that wags called one of the prisons the "American Bastille"

But, as the author points out, these were temporary measures. The founders knew in time of war that somebody, one person, had to be trusted for a short time to work outside the system as he saw fit. They gave presidents broad mandates. For times of war.

But now politicians have redefined the term "war" to mean just about anything. We have a war on drugs, war on terror, war on poverty, war on damned near anything. In addition, Congress has stopped declaring war, even when tens of thousands of soldiers die.

Finally, we toss terrorism into the mix -- amorphous, quasi-state-sponsored, with no real command structure and nobody ever to surrender. It'll just go on forever. Add that to wartime executive powers, and you've got a freaking problem the size of Kansas. Yet nobody seems to really come out and say it. Media personalities will ask every questions imaginable and not address the huge elephant in the room. Meh.
This HN post is a link to a disclosure from the security researchers who worked with Dropbox (note: I work for Dropbox).

It is not generally the case that companies disclose quickly-patched vulnerabilities that were reported by white-hat security researchers. Example of a similar vulnerability with a similar response time by another company: https://blog.duosecurity.com/2013/02/bypassing-googles-two-f...

Researchers disclose a while after the vulnerability is patched. This is standard practice.

Well, how else do you recover a rocket intact?

Parachutes have lots of trouble. The rate of descent they achieve is still fairly fast, so you need something to brake the descent at the end.

This is why various American capsules splashed into the ocean, as well as the Shuttle boosters, because the water acts as a cushion. However, dunking your delicate rocket in salt water is a bad idea. The American capsules weren't reused, and the Shuttle boosters required enough refurbishment afterwards as to make it not really worth recovering them.

You can land on land, but then you need some seriously hefty landing gear, or retro-rockets. The Soviets use retro-rockets fired at the last moment to recover their capsules on land. A rocket has problems that a capsule does not, though, namely that you need to keep it from tipping over once it lands! You can make a capsule fat, but a rocket really needs to be tall and thin, and any sort of horizontal velocity will have it falling on its side. You also have very little control over where the rocket comes to a rest. Again, tolerable for a capsule, but dropping your rocket into a forest is not going to be conducive to reusability.

You can add wings, like the Shuttle did, and land horizontally. Trouble with that is that wings are extremely heavy. Each pound of wing in the Shuttle was a pound of payload it couldn't carry. If you try to fit every stage of a rocket with wings so it can come back and land, you'll end up not having much excess capacity left over to actually carry a payload. Wings are great for aircraft, when you can use them to efficiently fight gravity for the whole flight. But they suck for spacecraft, where they don't help at all on the way up, and are just dead weight for most of the flight.

So landing a rocket vertically on its engines isn't really all that bad in the end. Inelegant, perhaps, but it has a lot of advantages. You get absolute control over where the rocket lands. You can land it as softly as you like. You can ensure that it touches down with no horizontal velocity so as not to tip over. You use the same engines that you used for the launch, so there's no extra weight there. The only real downsides are the need for some sort of landing gear, and the need to carry a bit of extra fuel. Neither one is all that bad.

When considering the stability, don't make the common mistake of comparing it to balancing a pencil. When the rocket turns, the motors turn as well, so it is not inherently unstable the way you might think. Rather, the stability is neutral: if you perturb the rocket, it will just stay in its new position, not returning to how it was before, but neither does it run farther away. A rocket that's slightly tilted will stay slightly tilted (gradually accelerating sideways, of course), it won't tilt over further the way a pencil does.

Note that Robert Goddard made this same error. He built his first rocket with the engines at the top, believing this would help with stability. So if you were thinking that way, don't feel bad: the father of modern rocketry did the same thing!
Apparently, it is fairly normal behavior; people activate a "leave plane" program. Having only one, they pick the one involving grabbing one's luggage before getting out of the plane.

Yes, okay maybe not on holiday jaunts. Before you can board a helicopter to an offshore platform and have to don a survival suit. With the risk of the helicopter flight being so high it is not really something complained about.

I think we can draw a lot of parallels between helicopter flights to offshore platforms and a shuttle into space.

Your wording implied that he preferred to keep slavery, which I guess was just inadvertent on your part. I didn't know that wasn't what you meant, so I took it at face value.

"If I could do X and Y, I'd do it" implies a preference for both. Anyway, I get what you mean now, especially since it's the same thing I said.

There's an interesting report on the A380 certification evacuation test[1] of ~870 people in 78 seconds. Granted, that was in a hanger with volunteers who knew it was going to come (but not when).

Serious fuselage damage might put enough exits out of commission to heavily bottleneck, though (although I think there's supposed to be some significant safety margin on those as well).

I disagree. What's wrong with needing a warrant ?

Right now, they don't need a warrant and I bet it's already causing problems for some people because government employees misbehave when you give them a grey area like that. That's just a fact.
And you're not gonna hear about it because people are powerless. They can't react to it because it will get them in more trouble.

Those who say that isn't true are the ones who haven't experienced it or are the ones taking advantage of others in similar ways.

And what makes it even worse is that the governments store all the data for years, maybe even decades. History has told us this is going to become a huge problem. For a lot of people. We may not live long enough to experience what can happen but it's just a matter of time. And this generation is responsible for it.

Consider it from the position of somebody in "upper management".

1. Technology lets a NSA employee do orders of magnitude more work than a Stasi employee.

2. Every employee may be a traitor or merely overly ambitious, but gains knowledge of how to evade detection while obtaining privileged information and taking advantage of it as a side-effect of working for you. As your organization grows you have to spend a lot of resources on internal policing.

3. Fewer employees also means fewer potential whistle-blowers.

Even without budgetary constraints, the NSA is well motivated to employ a much smaller percentage of the population than the Stasi did, assuming they are equally invasive. The ideal they are probably striving for is a completely automated NSA that reports only to the glorious leader.

I didn't say Lincoln preferred slavery. However, I did say that if it were possible to keep the Union (e.g Northern influence) and slavery, Lincoln would have pushed forward for compromise. However, the rift between the North and the South became too big.

As far as the spelling is concerned:
http://english.stackexchange.com/questions/75428/capitalizin...
http://www.standupamericaus.org/sua/wp-content/uploads/2011/...

It was common to use the lower case spelling for ``united" until the Civil War. Remember, you are citing the Federalist Papers, which supports a strong federalist government and thus a capital ``u." The Constitution, yes, capitalized, but some argue it was out of convention for title case. The Declaration of Independence used the lowercase ``united." It widely varied until the end of the Civil War.

They recommend doing that when the user "presses an action button or link". This is not the same as launching a browser extension.

Blindly following some person's recommendations doesn't even close to having good UI (or UX). eg. Opting for no confirmation and providing an undo option is an absolutely terrible idea for a 'format disk' button in an OS installer.
Not a mathematician, but "uncountably many" sounds like a loaded phrase unique to the field of mathematics. How does "uncountably many" differ from "infinitely many"? Are we not sure that it goes on forever or do we know that it's just an extremely large finite set?

Do you have a reference to the specific law? While dealerships are affected by a large number of federal regulations (fair credit reporting act, certain used car regulations, and others) I am not aware of anything on the books at a federal level regarding structure of dealerships.

Look at the wording of the petition itself: "States should not be allowed to prevent Tesla Motors from selling cars directly to customer"

That doesn't sound like a federal issue to me.
Ouch, that is one extremely non-user friendly feature going on there. The only reason it works at all is because most people use default for strings/numbers only.

This is a long post and merits a long response. I apologize if I'll be using HN as my draft board until I have answered or conceded to your points.

As far as your point that it's pro-Union versus pro-North, the Union in the 1860s is practically equivalent to the North. It doesn't detract from the fact that the North meant the Union, and the South the Confederation. Since all the states that attempted to secede are in the South, I think it's fair to say pro-Union is semantically equivalent to pro-North. However, pro-Union seems to be the terminology preferred by victors as it implies consensus while pro-North made it seem like regional differences (in truth it was). The Civil War was about regional differences largely over slavery. For instance, the South sometimes calls the Civil War by another name, ``the War of Northern Aggression." History is always POV. To indicate the indecisiveness on terminology, Wikipedia interchangeably refers to the Union or the North. It's absolutely about the differences with the North and the South. That's why the South attempted to leave the ``united States of America." If the South had won, I might argue that the USA wouldn't cease to exist, it just would only include a subset of the original members.

> Off-hand, some reasons not to: the aisles have limited capacity, and more bags in the aisles mean fewer people can be queueing ready to get off.

I can see what you're saying but "number of people queued in the aisles" isn't an important measurement at all. The important thing would how much the overall rate of passage through the exits is affected by the people who grabbed their bags.

I expect the rate of passage through those exits has a lot to do with what people do when they reach the bottom of the slide. That certainly might be affected by what they're carrying, but then again, people might have simply been tossing their bags over the side. You can't rely too heavily on a single photograph to analyse these things.

> I think people have taken the "keep calm" message to heart and, if anything, need to be taught to treat this kind of thing more seriously.

The alternatives are to keep calm or panic. I guess "seriousness" is subjective but when it comes to calmness vs. panic, I know which alternative I'd prefer the people around me to exhibit in an emergency. Particularly in a confined space. How is this even an argument?

Sorry you had to witness something that's not a tutorial for an already-popular javascript framework.
There's one thing worth mentioning here. There's an algorithm that checks if a graph has given minor. If you fix a minor once and for all, the algorithm that checks if graph contains a fixed minor has polynomial complexity. Together with Robertson-Seymour theorem, it implies that for any family closed upon taking minors, the problem of determining whether given graph belongs to it, is solvable in polynomial time: just check if it contains forbidden minors. Each minor can be tested in polynomial time, and there are finitely of them, so the whole algorithm works in polynomial time.

Now, the thing is: since we don't know the minors, we don't know the algorithm. In other words, we just non-constructively proved that some problem can be solved in polynomial time. We only proved that algorithm exists, we just don't know what it is.
Yep, just wanted to explain said confusion on my end, not trying to criticize. Glad we all agree!

NSA is much worse than the Stasi, because there is no free world out there.
I remember seeing a car accident once, a young guy in a mustang T-Boned a mini-van driven by a mother with an infant passenger. A moment after the accident, the woman got out of the minivan, walked around to the other side to open the working side door, grabbed her purse, and then calmly walked to the shoulder to wait for police. It was only after anybody asked her if there was anybody else in the vehicle that she realized her infant was still in the van, right next to where her purse had been. She ran over, retrieved her child and then went back to the curb, cursing herself the entire way.

(everybody was fine, there were no injuries).
Also, since it's an international flight, people's travel papers are likely in their backpacks, etc. If you take the time to grab your backpack, you may as well grab whatever else before you head out.
The natural numbers (1, 2, 3, etc.) are of course "infinite" - however, they are also "countable". (For any natural number you pick, if you count long enough, you'll eventually get to it.) That doesn't mean you'll ever have counted /all/ the natural numbers, but you can count to any arbitrary one.

For contrast, the real numbers, although also infinite, are "uncountable" - any way you start counting, there are real numbers that you will /never/ reach.
