Not everyone has a brand-new computer; The manuscript of the book I'm about to publish is in Open Office Word, about 400 pages and full of large images, and autosave is a real pain because it takes minutes to save the file.

Like another commenter said, I wouldn't make it the most important thing, overall efficiency is. But software speed is important to anyone with an older computer, especially a Windows computer, because the computer slows as the registry grows, and the registry never gets smaller, only bigger.

Sorry, what debacle with the F-22? Near as anyone can tell, it's the best air superiority fighter ever built and will be for the next 15 - 20+ years. Do they cost a lot? Yes. But don't compare the cost of opposing military aircraft to the cost of the F-22. Compare the cost of opposing military aircraft to the cost of the AIM-120 AMRAAM fitted to the F-22 because the first indication the opposing pilots are going to have that F-22s are in the area is a missile warning.

The Iranians experienced this already when they decided to send up planes to harass some US drone aircraft. The US sent an F-22 up and after the F-22 pilot got bored waiting for the Iranians to notice he was there, he radioed them to get out of his airspace.

"He flew under their aircraft to check out their weapons load without them knowing that he was there, and then pulled up on their left wing and then called them and said ‘you really ought to go home.'" http://www.military.com/daily-...

"I can't see the [expletive deleted] thing," said RAAF Squadron Leader Stephen Chappell, exchange F-15 pilot in the 65th Aggressor Squadron. "It won't let me put a weapons system on it, even when I can see it visually through the canopy. [Flying against the F-22] annoys the hell out of me." http://www.acc.af.mil/news/sto...

The F-22 isn't supposed to be dogfighting. The F-22 is supposed to blow the enemy out of the sky from BVR long before the enemy knows F-22s are in the air. That's why it was always so stupid to compare the fly-away cost of a new F-22 to the fly-away cost of other nations' aircraft. The real comparison is the fly-away cost of other nations' aircraft against the cost of the AIM-120 AMRAAM fitted to the F-22 that's going to blow their aircraft away.

If you have F-22s dogfighting with anyone, something has gone horribly wrong.

And the JSF is a flying pile of horse shit. We'd have been much better off building new F-16s, A-10s, and AC-130s. Let the F-22s own the skies, let the B-2s take out the nastiest air defenses, and then let all the cheap stuff fly in and mop up whatever's left on the ground. I don't know what the Hell problem the JSF is supposed to solve. If the problem were just that the US military has way too much money laying around, we'd simply build more F-22s, B-2s, and carriers. Obviously that's not the problem, so what the Hell is the JSF?

Whose fault is that? Pick up something used and cheap. Start interacting with local firearms communities and someone will probably give you something if you're that bad off and then take you to the range to show you how to use it. "I am unarmed" is the battle cry of those who've long laughed at the Second Amendment. If that's you, fine; stop laughing and get involved in some communities.

I currently have a web radio transceiver front panel application that works on Linux, Windows, MacOS, Android, Amazon Kindle Fire, under Chrome, Firefox, or Opera. No porting, no software installation. See blog.algoram.com for details of what I'm writing.

The one unsupported popular platform? iOS, because Safari doesn't have the function used to acquire the microphone in the web audio API (and perhaps doesn't have other parts of that API), and Apple insists on handicapping other browsers by forcing them to use Apple's rendering engine.

I don't have any answer other than "don't buy iOS until they fix it".

Super Dracos are for escape in flight too, including in and past MaxQ. But they are on Crew Dragon, not Cargo Dragon. Cargo Dragon did not carry a crew and wasn't programmed to save itself.

SpaceX has been very forthcoming with their telemetry data and analysis, so hopefully we'll hear what happened soon.

Most of us do have a need to transmit messages privately. Do you not make any online purchases?

Yes, but those have to use public-key encryption. I am sure of my one-time-pad encryption because it's just exclusive-OR with the data, and I am sure that my diode noise is really random and there is no way for anyone else to predict or duplicate it. I can not extend the same degree of surety to public-key encryption. The software is complex, the math is hard to understand, and it all depends on the assumption that some algorithms are difficult to reverse - which might not be true.

Most algorithms to do this use the time between keypresses, measured to very high precision so that the lower bits are chaotic. So it doesn't really matter what keys you hit, and it doesn't matter how rythmic your typing is.

The problem with FM static is that you could start receiving a station, and if you don't happen to realize you are now getting low-entropy data, that's a problem.

There are many well-characterized forms of electronic noise: thermal noise, shot noise, avalanche noise, flicker noise, all of these are easy to produce with parts that cost a few dollars.

True randomness comes from quantum mechanical phenomena. Linux /dev/random is chaotic, yes, enough to seed a software "R"NG. But we can do better and devices to do so are cheap these days.

I wouldn't trust anything but diode noise for randomness. If I had a need to transmit messages privately, I'd only trust a one-time pad.

Communism has been tried on a large scale - see Mao's Great Leap Forward.

Nope. That was a totalitarian socialist program pushing a collectivism that didn't work. Communism is a post-scarcity society and obviously scarcity was the thing Mao produced best.

Actually, it says "being necessary to the security of a free state. You see, the guys who wrote this had just risen up against their government and created another in its place. "A free state" doesn't mean "The United States of America"; it refers to a fundamental concept. That concept is one of a place free of tyranny. The men who wrote the Second Amendment would have gladly overthrown the government established by the US Constitution had it become sufficiently oppressive and tyrannical. They would have done so in order to ensure the security of a free state and they would have done so with their own guns.

We're covered for foreign enemies. We aren't covered from domestic ones. Tell me, what good would your argument have done if terrorists had attacked again before the 2004 elections and President Bush had called off those elections and simply declared martial law coast-to-coast, then stated that he would remain as commander-in-chief until the threat of terrorism was over? Assuming the army stood with him, what's your plan B for year-10 of the George W. Bush presidency? For year 20? For year 30? Oh right, you don't have one. Just "let's all hope that doesn't happen (because I'd be screwed!)".

Same with the electoral college. In the good old days, the state would have a vote in November, and would select the person(s) that would get up on a horse and ride to Washington DC to represent the state in electing the president. There was simply no other way. The electoral college became obsolete with the telegraph, but it's still around.

No it isn't. Abolish the Electoral College and watch as "flyover country" becomes exactly that. The top 20 cities would get 95% of every candidate's attention and promises. Anyone living outside a metro area may as well not bother showing up on election day.

The amendment remains relevant because it - like most of the US Constitution - is less a practical guide and more a statement of principles. Principles like the government not dictating what religion we should follow or what opinions can be expressed. The Second Amendment is a statement of the principle that when all else fails, no matter what, responsibility for establishing and maintaining freedom ultimately falls on the people, and that as such, they must always have access to the tools necessary to fulfill that responsibility.

It doesn't matter whether the tyrant comes from halfway across the globe or from just down the street; the people - all of us - have the responsibility to ensure that no tyrant lords over us. The people having the convincing capability to beat any challenge to their freedom ensures no such challenge is made. Despite all the dire predictions of fringe leftists in this country, there was never a chance President Bush would crown himself king; if for no other reason than even he would have to know it would end very poorly for him. Tyrants don't come to our country because of the US military. Tyrants don't come from our country because of the Second Amendment. The idea that we don't need the Second Amendment because we have the military is as foolish as the idea that we don't need the First Amendment because we have the Internet. Modern inventions don't negate principles; they reinforce the need for them.

More specifically, the weapons protected must be of a capability reasonably expected to be useful in fighting and winning against a foreign or domestic aggressor with state sponsorship. In other words, weapons equal to those possessed by any government around the world - including our own - which can be used effectively to win a war. Hence, full-auto machine guns, artillery, Apache gunships, and F-16s are fully in scope for the Second Amendment. What's more, there's an interesting argument to be made about even the classified stuff being available to the American people for study, purchase, building, etc.
