Comment Re: Thanks for pointing out the "briefly" part. (Score 1) 461

Red herring as is has always been. Idiots will keep making the useless point that the us is big. China will have no problem with it. They will pass germany this year. Actually they added 55% of Germany's total capacity last year and still accelerating deployment.

Not a red herring at all.

One...China doesn't have a power grid that's about a century old...they built most of theirs in the last 15 years. So it's a different architecture entirely. Ours looks a lot like extension cords plugged in, running north-south.

Two...the Chinese power grid is still wildly unstable...go there sometime and see for yourself.

Three...you're totally far off in your statement to begin with; China is not only more than two orders of magnitude more dirty than the US per watt in terms of all emissions (carbon, sulfur dioxide, heavy metals, etc.), they are also nowhere near getting to anything like Germany has. They may make a lot of PV equipment, but they don't use much of it themselves.

Or have you not noticed that every Chinese city is totally covered in smog?

What does 22GW look like? If all of the collectors and ancillary equipment were in the same place, how many acres would the facility be?

It looks like about 2 percent of total generation capacity in the United States (which has a bit more than 1,000 GW).

And this is something that makes me crazy when talking about Germany's initiatives. I think what they're doing is fantastic, and definitely the way of the future, don't get me wrong. But there are posts in Slashdot that are the equivalent of, "Oh, let's just do the same thing here to...it looks easy!" And nothing could be farther from the truth.

Issue 1: Geographic size.
Renewables are great in that they *can* be cheap and are, almost always, quite clean. But in the US we have a couple of challenges. One, the best place for wind farms is not too close to large population centers. Sure you can put a few wind turbines here and there, but if you want meaningful amounts of power, you need to take advantage of lightly-populated regions with lots of reliable wind...and these aren't exactly close by to cities. Given the amount of area that a solar farm takes up, the same holds true there as well, though not always to the same degree of distance. Now, enter VARS. Without voltage support, the power won't travel these long distances. T. Boone Pickens made this mistake...he got ready to build out large wind farms, and then suddenly discovered that the distance over which the power had to travel to get to the people who needed it was a nightmare.

Issue 2: Balancing.
Power grids must keep generation and load in balance. Otherwise, you get multiple bad things, including underfrequency and overfrequency events. I won't go into the full details of that (it's a rabbit hole) but suffice to say that it is very very bad. And the balance doesn't just have to be within X power company, as they are interconnected with their neighbors. Entire groups of such companies themselves are organized into managed groups under the control of a Balancing Authority. In some markets there's energy trading, and in others it's more tightly regulated so that such speculation isn't permissible.

But I digress. Under the old way (nuclear, hydroelectric and fossil fuel generation) load was variably predictable and uncontrollable by the power companies, but generation was something they had solid control over. If load went up, they either increased output at a plant or spun up reserve capacity...if load went down, they went the other way. But when you have renewables, you lose a degree of that positive direct control. The wind slows down and your wind turbines suddenly push less power. The sun comes out and you suddenly have more watts on the grid than you want to have. In Hawaii, HECO has issued a moratorium on new solar panels on homes, because it's so bad that it's threatening to destabilize their grid...the only grid on the planet where one single modern power company has control of the whole thing. (Hawaii isn't interconnected because, well...see above over 'nightmare of pushing power over long distances'.) And just the number of people who have their own photovoltaic panels on their homes is causing them grief. Because of how unpredictable sunlight is...in Hawaii. Yeah, it really is that freakin' bananas. It was expected based on their ideal combination of zero interconnectivity, steady weather and fairly stable power consumption levels (not having industrial facilities makes load prediction pretty easy) that they could support 20% penetration of distributed power generation using PV. They're at 10% now, and in trouble.

So, yeah...in short: Germany's done a great job leading the way. But their power grid is 1/20th the size of ours in terms of power generation/usage, and their nation is also a fraction of ours in size. So what they did can't just be copied and pasted into the US to get us to the same proportion of renewable generation.

Yeah, but Intel and AMD will go bankrupt if they make chips just for "some of us." And if you look at where Intel has gotten their speed increases, very little of it in the past decade has been from clock speed. Ghz is no longer where the performance boost is to be found.

Nope, Liquid Nitrogen cooling gets you past the speed limits. How about over 8Ghz on a chip that costs less than $200? Going to Helium and you can get over 8.5Ghz. although both become a bit unweildy when it comes to game play because I don't want my hard drives to freeze. I love that last video there's some real country boy engineering there including using a propane torch and a hair dryer to keep certain components from freezing.

I'm a little confused as to why you're citing the chip's low low price of "less than $200" if you need liquid nitrogen to get it to perform the way you want it to. You do realize that cooling systems cost money, too...right? There's no point in being able to use a cheap processor to get to X performance benchmark if the required additional support systems cost thousands of dollars more than a more powerful and more expensive processor that can do it out of the box. Not to mention the fact that liquid nitrogen cooling isn't exactly hassle-free, especially in a household environment. And it's worth noting that even if you boost Ghz, you eventually run into choke points related to pushing data to and from the chip anyways. You can give the most important worker on an assembly line all the crystal meth they can eat, but they can't work any faster than the conveyor belt in front of them.

Comment Re:What about statistics vs calculus (Score 1) 155

Practically speaking, basic familiarity with statistics is also a form of civics - teaching kids when to call BS on bogus claims

Indeed. I have long felt that we should be teaching "bullshit math" where rather than getting a problem and finding a solution, the students are presented with a political advocacy statement, and tasked with identifying the logical and mathematical flaws, unstated assumptions, and missing information. This sort of critical thinking skill, along with learning basic economics, could lead to a better functioning democracy.

The "bullshit math" you refer to is known as Symbolic Logic. It provides a mechanism for reducing statements and concepts into operands, effectively...and by doing so you can more easily detect things like non-sequiturs, circular logic, self-contradiction, empty statements with no real meaning and the "post hoc ergo propter hoc" bullshit that is the basis of many knee-jerk legislative actions. The real beauty is that by sticking to the symbolic operands of a statement rather than the contextual content, you can strip away information that triggers an emotional response (terrorism, child porn, etc.) and recognize when someone is just plain full of shit.

And I agree greatly; teaching this is an excellent idea. It's a cornerstone of critical thinking, which in turn is a cornerstone of good citizenship in a democratic society. But if you don't seek it out as a college course, you'll probably never hear about it. That should change.

Comment Re:AP is what exactly? (Score 1) 293

They keep mentioning AP but its not actually written anywhere what this abbreviation stands for.

"AP" means "Advanced Placement". It is basically a college level class taught in high school, and intended for advanced college-bound students. The "news" in TFA is that "average" students would have difficulty in these classes. In other news: the sky is blue.

There's another layer to this, however. If you look at the practice exams for the AP CS course, you'll see that it's not computer science that's being tested as much as how to program in Java. Useful, yes, but not exactly as broad as the title would suggest.

It seems to me that if there's a desire for greater CS knowledge in high schools, then teaching things from an architectural level first would be a smarter choice. Much like driver's ed; you don't learn how to design an engine, but you learn that a car has one, and how it relates to the transmission, tires, brakes, etc. I would think that for the computer literacy purposes of most people, knowing how to finish an incomplete java applet is nowhere near as useful as understanding the way different parts of the architecture interact when they browse a website or set up a wireless network at home.

And when you really look at the complaints of other nations, it boils down to objections over how damned good the NSA is at it, since the complaining nations either have their own capabilities or are so primitive *cough, Afghanistan, cough* that they couldn't even dream of attempting it at this time, but are hardly squeaky-clean in their behavior in other areas.

Granted, they aren't in the music industry, but I don't blame them...the music industry is still trying to figure out which end is up from the combination of iTunes/Amazon's upending of their distribution channel and the after effects of them deciding to sue their own customers like a bunch of idiots.

Since 1948, there's been a ruling by the Supreme Court in the case of United States v. Paramount Pictures that concerned whether or not Paramount's vertical integration (movie production, movie distribution, movie theaters...with exclusive rights down the pipe) constituted a violation of the Sherman Antitrust Act. Indeed, it turned out that it was, and as a result there has been a long-standing prohibition on that degree of integration from that day forward. Now, it's easy to just point and say, "Hey! If Comcast makes movies and shows movies on their own channels, that's a violation!" It isn't, the way the ruling exists, because Comcast also shows movies from other sources as well. But the needle has been moving in that direction, obviously. But in a way, this isn't a new problem either, and there's hope that it can be addressed.

Dye packets in the bottles, like they use in Bank robberies would be interesting as well.

I think you fail to understand how cash and pills work, particularly in how they are packaged.

Money, you see, is mostly validated using visual means. A vendor tells me that something costs $15, and I hand over two bills...one that is worth $10 and one that is worth $5. He/she then looks at said bills, seeing that they are indeed money and also in the right denominations, and the transaction is concluded. If I hand over two $1 bills, the transaction will fail, or if I hand over pieces of paper that feel like money but aren't, then the transaction also fails. Conversely, at my end, I'm checking to see the value of the bills (and that they are the right kind of currency as well, in my case, since I have both euros and dollars in my wallet) are what I need to complete the transaction. So right there, two different parties check each bill once, visually.

Furthermore, the fact that money is visually assessed so frequently and by multiple parties makes for value in 'destroying' money by marking it in a manner that indicates that it has been wrongfully acquired. Marking from a dye pack accomplishes this. So, a dye pack destroys money by rendering it visually tainted.

Pills on the other hand, are stored inside bottles. The thing about bottles is that they are intended both to keep the pills together and facilitate physical shipping and inventory in pre-defined quantities, and also to protect them against contamination. And people who are buying prescription meds already assume that they are wrongfully acquired...and even if they are not, they are about to be anyways, so visual marking wouldn't matter on the bottles in the first place. Indeed, it may even help confirm that the goods are of high quality for having been stolen from a reputable source. And while money must be transferable between illicit and licit actors to retain its usefulness (what good is money you can only pay crooks with?), drugs that enter the black market stay there, so nobody cares if the law was broken in their acquisition. So a dye pack is useless in the context of prescription medication and may actually serve as an accidental validation of the provenance of the stolen goods.
