Comment: Lead Acid (Score 4, Interesting) 290

Lead acid batteries are still about half the price per kWh (look near the bottom, at the 48v x 400Ah bank), and come with the same 10 year warranty. Cars care about weight, houses don't.

The new thing here isn't battery storage of solar power, it's lithium-ion batteries instead of lead acid. The price performance for lithium-ion can't compete with lead acid yet, when weight isn't a factor.

No, that's actually why the U.S. patent office stopped accepting applications for perpetual motion machine patents. They wasted uncountable hours debunking experiments that seemed plausible at first glance but always just ended up wasting everyone's time.

It's not just that Shawyer's claims violate conservation of momentum. The Alcubierre and Natario drives also violate conservation of momentum, but at least they explain that violation in the context of Noether's theorem. In contrast, Shawyer just made a ridiculous mistake by forgetting that the normal force a microwave photon exerts on a surface is always normal to that surface. Sadly, Shawyer seems to have duped a lot of otherwise skeptical people into uncritically cheerleading his absurd claims.

Whistleblowers have been coming forward, the people have been loudly criticizing it, we elected the Presidential candidate who was most opposed to it in both of the last two elections (the second guy was distinctly more of a "lesser of two evils" than the first), and we've been taking them to court.

So, to recap, that's soap box, ballot box, and jury box that we've been using. To claim that we're letting them get away with it is to betray your ignorance of the facts. Short of revolution, we have done everything we can. This is the oligarchy ignoring the law and the will of the people.

And if "But I have other classes!" is the best excuse that you can come up with, then you're going to deserve it.

Hey, that's not fair. OP clearly stated that he was also busy trying to get laid and did not understand the course material. Clearly when you add those two elements he deserves at least a B-.

TL;DR: The upside of being under continuous surveillance is that everyone else is too. It is the same argument as, "Because terrorists might get caught."

Here's just one example of the downside: Alcoholics Anonymous, Narcotics Anonymous, and similar will all have zero attendance as soon as employers stop hiring people who have been seen at an AA/NA meeting. That will be a reality within ten years, as private license plate tracking databases come online.

Doubt it? Ask yourself this: Would a typical "profit over everything" manager hire someone he knew was in NA? That guy is going to abuse these databases as they come online. That is reality.

I'm gonna pretend you're actually interested in the answer, but let's face it, we're really talking past each other, to our fellow Slashdotters. Thank you for smoking.

The reason for the mass move to encryption -- like Wikipedia and Google moving to default HTTPS, and people like me working on making encryption more approachable by the masses -- was the revelation that non-suspects were being monitored. That is why there is now a haystack within which to hide the needles, and that is why the encryption is now too strong for the intelligence agencies to break when we really want them to be able to.

Moreover, while I'm here, and since I want terrorists to get caught, let me add this: The solution is not increasing the level of distrust between citizens and government. The solution is restoring the reasonable, moderated, level of trust that we used to have in the executive branch. That starts with the ones who created the rift, and that is not the people who were sending all their traffic in the clear; it is the assholes who recorded it all and denied they were doing it.

Intelligence officials were, behind the scenes, questioning whether the benefits of gathering counter-terrorism information justified the colossal costs involved. Then Snowden went public and essentially forced the agency's hand.,

So they could have said, "OK, you know what, you're right. The benefits of this program are outweighed by its costs, the American people have a right to be involved in the decision about surveillance, and we are going to shut the program down." They would have been the bigger men, demonstrating that standing united is more important than ego.

But instead, they cried, "NO! If it's your idea, if you're trying to force us to stop, well then FUCK YOU! We'll do what we want, whether you like it or not! YOU CAN'T TELL US WHAT TO DO!" Like a petulant child throwing a temper tantrum. Can't back down from a fight, that might make them look like they don't have a giant chip on their shoulders.

As expected, Jane provides absolutely no links to back up any of his accusations. And still no evidence that Jane grasps the irony of his lecturing scientists about what scientists think.

And Jane still hasn't admitted he was wrong when he repeated the same false Sky Dragon Slayer things in public over and over.

... Are you aware that the KKK has historically been tied to the Democratic Party of the U.S.? Look it up. [Lonny Eachus, 2014-12-16]

And we should never forget that the KKK was primarily a Democrat organization. Many people don't remember that. [Lonny Eachus, 2015-03-08]

Abe Lincoln: the ultimate "white supremacist". He wanted to end slavery IN ORDER TO send them all back to Africa. #RealHistoryNotSchool [Lonny Eachus, 2013-12-17]

Abe Lincoln was the most openly racist President in history. Obama visiting Lincolns' memorial is a tribute to ignorance. Lincoln wanted to end slavery because HE WANTED TO SHIP ALL THE BLACKS BACK TO AFRICA. It's history. Read it. Get educated. And by the way, yes Lincoln actually TRIED to ship some former slaves away, but it ended in disaster. Look it the f* up. [Lonny Eachus, 2014-05-26]

... Lincoln was a racist among racists. Lincoln wanted to end slavery BECAUSE he wanted to send all the blacks back to Africa. He even tried to implement the plan. [Lonny Eachus, 2014-07-07]

Lincoln did not like negroes. His stated reason for wanting to free them was so that he could ship them back to Africa. He actually sent one ship full of them to the Caribbean as a trial run. Most of those on board died from smallpox. He was preparing a second expedition when the Civil War broke out. ... [Jane Q. Public, 2015-03-21]

Gosh, how could anyone admire a man who was assassinated three days after proposing that some black people deserved the right to vote? Must be a tribute to ignorance, that's the only answer.

Only one person can save the day. Jane/Lonny Eachus, we need you to leap into action and keep lecturing "the black people" on how ignorant their choices of heroes are. Maybe after enough mansplaining by old white guys, we'll finally be able to heal as a nation.
