Did you mean this guy?

Sorry, yes, Eric. I have no idea why my brain found Josef in that slot in my memory and didn't even question it.

Could Maroney Be Prosecuted For Her Own Hacked Pictures?

Areyoukiddingme Re:In Theory? (274 comments)

Oh look. Another numbskull with no clue what the word means, but spells it with the extra a because they think it makes them look/sound smart.

Most people don't know that ephebophile is a word. Including the Firefox spellchecker, I might add.

MIT Study Outlines a 'Perfect' Solar Cell

Areyoukiddingme Re:Might be viable (110 comments)

Interesting 85 percent absorption rate, though.

And highly suspect, considering the theoretical upper limit is 86%. The number of real machines that achieve that high a percentage of their theoretical limit is vanishingly small. Unless Josef Drexler has managed to perfect a nanoassembler that builds solar panels, that 85% isn't happening.

It's young men queuing with plush mushroom hats...

What I want to know is where is my plush mushroom hat? I've been gaming on PCs since the '80s and I never got my standard issue plush mushroom hat. I want my hat.

35,000 Walrus Come Ashore In Alaska

Areyoukiddingme Re:But WWF still advocates for huning polar bears. (292 comments)

They're not concerned about helping bears and other animals, they're concerned about making money.

That much should be obvious when they claim a mass walrus haulout is bad for polar bears. That's just idiotic. As far as the polar bears are concerned, it's free lunch. A LOT of free lunch. This is going to cause a mild boom in polar bear population in the spring, because many mothers will be well fed this fall.

35,000 Walrus Come Ashore In Alaska

Areyoukiddingme Re:The problem with double standards. (292 comments)

Or the giant areas of highly acidic oceans that lack enough oxygen for fish to survive. Both of these are from us burning fossil fuels.

No, that's not. That's from us dumping massive amounts of nitrogen fertilizer into watersheds, causing algae blooms, which suck all the oxygen out of the water. It has nothing to do with burning anything.

Laying the Groundwork For Data-Driven Science

Areyoukiddingme Save Money (55 comments)

I can save the NSF a bunch of money with this initiative. There's a data center in Utah that's not being used (for anything legal) with a huge amount of data storage capacity. The NSF should have it.

Obama Administration Argues For Backdoors In Personal Electronics

Areyoukiddingme Re:Update to Godwin's law? (575 comments)

What I don't understand is the lack of concern about security.

I'm far more afraid of a terrorist/criminal organization getting access to these back doors, and reading all of the encrypted documents that companies (including government contractors) want to secure, than hidden communication allowing them to get away.

Let us consider for a moment how huge the black market is for exploits today. That market is huge while pursuing only the hope of finding a way in. Now imagine what happens when there's a government guaranteed way in.

Obviously the US Congress should move immediately to enact this law. After all, think of the Nigerian children.

Verizon Wireless Caves To FCC Pressure, Says It Won't Throttle 4G Users

Areyoukiddingme Re:4G is Losing to Wifi (46 comments)

It's not PR spin. They're not allowed to throttle LTE service for grandfathered unlimited accounts. It's part of the agreement they made with the government when they bought the 700Mhz spectrum. They were probably hoping everyone had forgotten.

What were the terms of that agreement, exactly? Because they sold the 700Mhz spectrum they bought to T-Mobile for $2.4 billion. Are they still bound by the terms of that auction, even though they no longer hold the fruits of that auction?

The $1,200 DIY Gunsmithing Machine

Areyoukiddingme Re:Ok, several aspects to this. (651 comments)

White hats? If white hats were building actively guided systems capable of that sort of range, you'd be seeing miniature computer boards running Linux, Squid and Tor relays launched into stable orbits that crossed nations with restricted network access. We don't.

I don't usually comment in the gun threads, since it's not my hobby, and usually someone would have noticed this remark and answered it by now, but we're 400 posts and counting into the thread and still no one has, so I will.

We do. Ham radio enthusiasts (who have a not-inconsiderable intersection with gun enthusiasts) have put multiple relay satellites in orbit, and you could call them miniature. They're certainly reasonably small compared to normal commercial satellites, even if they're mostly not CubeSats. Some of them are intentionally put into inclined orbits, so they cover more of the Earth's surface, including crossing nations with restricted network access. No, they don't build actively guided systems of their own to do it. They launch as secondary payloads. They operate mainly as store-and-forward systems. Email, basically, or Internet newsgroups.

I don't recognize your reference to neocon stupidity, but I concur that it was stupid. There are existing orbital solutions to the problem of rampant censorship.

Elon Musk: We Must Put a Million People On Mars To Safeguard Humanity

Areyoukiddingme Re:The cost? (549 comments)

As usual, when I hear futurists telling us about the awesome the future will be ... I find myself thinking "this is impractical, way more than anybody will ever be able to afford, and probably never going to happen".

In the future, you will be able to carry a device in your pocket that will allow you, for less than the price of a cup of coffee, to have a conversation with anyone else on Earth who has a similar device. On a whim.

The future could be awesome. But no, no one will ever build such a system. It's impractical, way more than anybody will ever be able to afford. And there are so many details, and it would require such a huge planet-girdling system. It can't possibly happen.

...

You underestimate what feats of engineering have already been accomplished, and overestimate the size of the feat Elon Musk is talking about.

Energy Utilities Trying To Stifle Growth of Solar Power

Areyoukiddingme Re:Survival (488 comments)

Show me an example of these codes please. I have been researching this for the past two hours and have looked at multiple occupancy permitting codes across the U.S. and there just isn't any such requirement that I've been able to find.

The codes you're looking for tend to be at the city, township, or county level. A great many of them have not been put online yet, and haven't really changed in 30 or 40 years.

Hong Kong Protesters Use Mesh Networks To Organize

Areyoukiddingme Re:I wonder what a government node could do. (85 comments)

I wonder how much information one mesh node could accumulate to incriminate other participants? How many of "the people" will be willing to participate in an uprising like this if they know that a government stooge is likely no more than two or three hops away?

You do realize that most of these protesters are literally standing two or three steps away from a government stooge wearing riot gear, right? It's not like they're even trying to blend in.

I think we're forgetting our history here. Peaceful protest only works if it seriously inconveniences as many people as possible for as long as necessary. Politely camping in a park without a permit doesn't really cut it. If they're using tear gas on you, it's a start. If they're using water cannon on you, you're getting somewhere. If they're setting dogs on you and hauling you away to county lockup by the busload, you're doing it right.

People forget exactly what happened during the Civil Rights movement in the United States. It's peaceful protest only on the protester's side. On the side of the so-called civil authorities, it's decidedly not peaceful, and rarely civil. And this has to go on for quite a long time. Literally years.

Occupy Wall Street accomplished nothing because none of that happened. These protests in Hong Kong will likely accomplish just as little. They're carefully avoiding inconveniencing anyone. Nothing happens if you do that. We demonstrated exactly that in the US. Hong Kong should learn from our mistakes. If they want to actually change things, they have to get obnoxious and get hauled away by those riot gear-equipped policemen. In droves. By the thousands. Or since we're talking about Chinese numbers here, by the tens of thousands. (It takes some serious effort to match per capita numbers in China.) Being careful not to interfere means you can be ignored, not just by authority, but by the man on the street as well. You must inconvenience people. You must interfere. You must do so as peacefully as possible, but you must do so.

Most recently, the US did it wrong. We in the US weren't willing to pay the price to get the oligarchs to back down. The populations of several Arab states did it right. Yeah, it hurts. Sorry, but that's what it takes. Are you in China ready?

Energy Utilities Trying To Stifle Growth of Solar Power

Areyoukiddingme Re:Catastrophe? (488 comments)

GP did specify a buried flywheel. If pieces of flywheel become embedded in the soil four or five feet under my lawn, I fail to see the catastrophe. A one- or two-percent annual failure rate for a device like that would be quite acceptable.

Catastrophe is more than danger to life and limb.

When an engineer uses the term, it can mean (and does mean, in this case) that the device is not repairable after the incident. Failures can be fixed. After a catastrophic failure of a flywheel, you're in your yard with a backhoe, digging up the old one, because not only did it disintegrate, it blew apart its generator with shrapnel, shredded its housing, and probably induced a surge in your house current as it went. And now you have to buy a new one and replace it completely, including digging out the remnants of the old one because you don't want to dig a whole new hole somewhere else, with all new wiring, and do it all over again the year after that.

A one- or two-percent annual failure rate for such an expensive device is a financial catastrophe, at the very least.

Energy Utilities Trying To Stifle Growth of Solar Power

Areyoukiddingme Re:Survival (488 comments)

Why batteries? Spin up a buried flywheel in a vacuum.

Because flywheels aren't actually all that energy dense, even after quite a few years of development. To store more energy, you want bigger radius, more mass, or higher speed. There are material limits to all of those things. Push any of those criteria too far and you end up with a flywheel that has a distressing tendency to self-disassemble. Catastrophically.

Oddly enough, as difficult as it is, the materials science of figuring out more efficient ways to store electrical energy by moving ions around is still easier than the materials science of keeping spinning-very-fast things in one piece.

Energy Utilities Trying To Stifle Growth of Solar Power

Areyoukiddingme Re:Survival (488 comments)

Unless the code specifically requires that you be connected to the electrical utility grid there's no problem.

That's just the thing. Some codes do specifically require a grid connection. Building codes and accompanying occupancy permits are a perfect example of small government at work. They vary from county to county, and can even be contradictory. Of course they can't contradict state or federal codes, but they don't have to match each other. Some counties seem to take positive delight in piling on additional restrictions, on top of state codes. For the property values, of course.

So yes, there does have to be a minor revolt against codes, in many places across the nation. They were worded a little too specifically, once upon a time. A conspiracy theorist would be inclined to suspect power company lawyer involvement in drafting those codes, and I bet if you turned over enough rocks, you'd find a few. Mostly it's just sloppy language though.

Former GM Product Czar: Tesla a "Fringe Brand"

Areyoukiddingme Re: Yeah ... but ... it's true. (267 comments)

Learn to read. He's claiming Tesla has a significant profit margin per car. That is false as is shown by their SEC filings.

It's true. Sale price per car minus expenditure per car equals profit per car, and it is indeed 25%.

The company has negative net revenues because they're busily pouring money into capital investments, tooling up production lines for new cars. It's not like $700 million has vanished down a hole somewhere. They're buying real estate and massive amounts of machinery. Starting a car company from scratch requires investment. You don't just wave a hand and cars start pouring out of a door in the side of a building.

Man Walks Past Security Screening Staring At iPad, Causing Airport Evacuation

Areyoukiddingme Re:No he didn't (217 comments)

In particular, hiring a human being to stare at a hallway for 8 hours a day to make sure nobody walks this way instead of that way is not a good design.

It's perfectly fine. The TSA jobs program is working as designed.

Marines Put Microsoft Kinect To Work For 3D Mapping

Areyoukiddingme Re:If you really had piles of $, ie the DOD.... (37 comments)

The Marines deploy to austere environments, so their requirements are typically a little different. Large rooms like the one you linked might work for the General's briefing in the rear (though I can't imagine a single Marine facility that would pay for something like that), but battalions downrange need something a little smaller. IAAFM (former Marine).

Judging by the former Marines I've known, the last thing a Marine wants is yet another electronic gadget that doesn't work with yet another battery that always needs charging. I suspect this little toy has a long way to go before it convinces a Marine there's something better than a plastic film topo map.

26" FED volume production in 2009?

Areyoukiddingme Areyoukiddingme writes  |  more than 6 years ago

Areyoukiddingme (1289470) writes "Field Emission Technologies of Japan claims they will begin volume production of a 26" FED at the end of 2009.

To help it meet the mass-production deadline in late 2009, FE Technologies will acquire Pioneer's Kagoshima plant by the end of 2008. The Japanese company will invest $183 million to $274 million (20 to 30 billion yen) in manufacturing equipment.

...

The initial application for FE Technologies' 26-inch FED panels will be as "master" monitors, used by TV broadcasters to check picture quality.

No word on price, but you can bet the answer is "if you have to ask, you can't afford one." As a Sony spin-off, they should have some legal cover from the patent trolls. Could full color full size FEDs finally escape the vaporware tag?"
