Bloom boxes are fuel cells that create electricity using a variety of energy sources. Powered by natural gas, they could produce cleaner power for Western homes. Running on plant waste, they could bring grid-less power to developing countries. And they could also be used as storage/backup for solar and wind generation.

These matters were brought to Ms. Langley's personal attention through complaint to the FEC weeks ago, but she and the Committee continue to solicit contributions fraudulently, and have stubbornly refused to return the contributions that they already have, received. Therefore, Ms. Langley and the Committee should be fined, and Ms. Langley imprisoned for five years.Again, there is an issue with falsely soliciting political contributions, but the thing is, she wasn't getting much attention for her campaign, and the issue of where she lives is really quite minor. There are always people who oppose elected officials. But sending this letter and requesting five years in jail for Langley suddenly made this a national story -- and guess who that's helping? It's certainly not Grayson. But I understand that Langley has suddenly found a lot more willing donors to her campaign. Wouldn't Grayson have been better off just focusing on his "guts" and not why someone outside his district thinks he's "nuts"?

Reading an End-of-the-Decade baby name round-up, I ran across this:
The last few years have shown a dramatic increase in the influence of everything from blockbuster movies to celebrity babies on naming trends ... Marley, from the film "Marley & Me," is gaining numbers for both sexes.
"[Parents] may not be able to send their kid to Harvard or buy him or her a celebrity lifestyle, but names are free and can give a piece of that cachet," Murray said.
No Harvard for you, kid. But we named you after a dog. So there's that.

To be honest, I'm not really sure what is going on here, but it looks fun. Arne Hendriks and Bas van Abel have collaborated to create the Instructables Restaurant, an eatery where everything inside it- including food, furniture and entertainment- have been constructed from designs available for free on Instructables. They are still in the trial phase of the project, so they don't have a permanent location, but their inaugural event appears to have gone quite well.
Of course, if you would like to make your own, there is an Instructable for that.

We were recently discussing the Discovery Channel series, Dirty Jobs on an internal Maker Media email. We all admire Mike Rowe's dedication to rolling up his sleeves and getting down to work and the happiness that can be found in working with you hands, even if the process is filthy. I've been a Dirty Jobs fan for a while, and an article in Fast Company about Mike Rowe back in February 2008 really solidified my admiration for the man. He also gave an insightful Ted Talk back in March of 2009 that is well worth watching. I've watched Mike make marbles, deliver a calf, and grease the parts of the crawler that delivers the space shuttle to the launch pad. It's great, great fun. If you haven't watched Dirty Jobs before, today is a great day to jump in on the fun. Discovery is airing a day-long marathon of the show right now. Enjoy!

"169A. Remedy for groundless threats of infringement proceedingsWhile it would be nice to see those who are falsely accused of copyright infringement have at least some stronger legal rights, it seems unlikely that this gets anywhere.
(1) Where a person threatens another person with proceedings for infringement of copyright, a person aggrieved by the threats may bring an action against him claiming--
(a) a declaration to the effect that the threats are unjustifiable;
(b) an injunction against the continuance of the threats;
(c) damages in respect of any loss which he has sustained by the threats.
(2) If the claimant proves that the threats were made and that he is a person aggrieved by them, he is entitled to the relief claimed unless the defendant shows that the acts in respect of which proceedings were threatened did constitute, or if done would have constituted, an infringement of the copyright concerned.
(3) Mere notification that work is protected by copyright does not constitute a threat of proceedings for the purposes of this section.
(4) A copyright infringement report within the meaning of section 124A(3) of the Communications Act 2003, if notified to a subscriber under section 124A(4) of the Communications Act 2003, does constitute a threat of proceedings for the purposes of this section."
A couple of weeks ago, I ran across yet another news story about how young people no longer date—they just have friends with benefits—and how those hookups are liable to lead to emotional and psychological damage.
But recent research suggests that picture may be wrong. Published in the December issue of Perspectives on Sexual and Reproductive Health, the new research was based on surveys answered by a diverse group of more than 1300 Minnesotans in their late teens and early 20s. Not only were the majority of these people having sex within a relationship, but whether they were or not had no bearing on their mental health. The casual-sex havers were every bit as happy and healthy as the kids who were only doing it with a committed partner.
So who's right? To find out, I turned to a couple of experts in teen sex and sex education. At the heart of this apparent discrepancy, they told me, are big differences between the way scientists study sexual behavior and the way that information gets presented to the general public.
For instance, let's go back to that question of casual sex. An older paper that found 78% of young people had at least fooled around with a stranger or acquaintance during their college years. So it was surprising when the Minnesota study turned up just 8% of respondents who's last partner was a casual acquaintance, and another 12% who were in a relationship, but not an exclusive one.
That's a big difference, but the reason behind it should be instantly apparent to any current or former teenager. At least, any who have been to a slumber party. It's as simple as the difference between of-the-moment gossip and a game of "Have You Ever". The Minnesota survey asked people to categorize their most recent sex partner. The earlier study asked whether they'd ever, at any time, got all up on someone they didn't know very well.
Both are legitimate questions. The problem is that they're often reported by the media as being the same question. And neither "Have you ever?" nor "What are you doing right now?" is really a great stand-in for the far more important, "What do you normally do?"
"I think people stereotype teenagers sometimes," said John Santelli, M.D., a pediatrician and adolescent health specialist who chairs the Heilbrunn Department of Population and Family Health at the Mailman School of Public Health at Columbia University. "I don't think hookup situations are the norm for young people. Serial monogamy is very common among youth. The 20% in this study who weren't in committed relationships, I'd be willing to bet that many were between relationships, or in the process of forming one."
Far more thorny is the question of whether casual sex, or any sex outside marriage, is emotionally harmful. That basic idea is stated as a fact in federally funded abstinence education programs, Dr. Santelli told me. But most scientists don't think it's so clear-cut. Dr. Santelli, as well as adolescent sexuality researcher Douglas Kirby, Ph.D., told me that teen sex and mental health are more of a chicken/egg conundrum—and which came first depends a lot on how old you are.
Correlations between sex and poor mental health do turn up for very young teenagers—people younger than, say, 14—Dr. Santelli and Kirby told me. But you can't separate that from the fact that sex at that age, particularly for girls, is more likely to be coerced—and being pressured or forced into sex you really didn't want to have can cause mental health problems on its own. Dr. Santelli also pointed out that children who have been abused at home are more likely to start having sex early. Again, you can't look at any depression or addiction those kids have later and say that early sex was the clear cause.
Kirby said the same holds true for slightly older teens—people who were younger than 17 when they started having sex.
"Young people who are risk takers, more non-conventional, or challenging of social norms, they're more likely to have sex between the ages of 14 and 17. They're also more likely to smoke cigarettes, try alcohol, use drugs, be less attached to school, drop out, etc.," Kirby said. "Again, it's not the case that sex leads to all those things. It's that these people who are less connected to family and school are engaging in a wide variety of risk-taking behaviors and sex is just a part of that."
The median age for when Americans lose their virginity is 17. After that, Dr. Santelli and Kirby told me, studies show there's no longer any real correlation between poor mental health and sex. Whether you have it or not, your psychology isn't effected. The Minnesota study backs that up, they said, and goes one step further by showing that who you have sex with doesn't really matter, either.
Again, the problem is that media seldom make distinctions between situations that represent cause-and-effect and those that are simply correlated.
The result is that we, as a society, aren't addressing the things older teenagers and young adults really need to know, Dr. Santelli said. Americans start having sex at 17 and get married around 27, he said, but abstinence-based programs are presented as though getting married right out of high school is still the norm.
"We aren't providing realistic social models to young people. We need a healthy cohabitation program in America. And healthy relationship education," Dr. Santelli said. "We just say how wonderful marriage is. Abstinence programs are aimed toward getting you married at 20, not supporting you and helping you make healthy and smart choices as a single 20-something. We don't really support long-term, non-married monogamy. Which is a pretty good choice for many young people."

"Old air discovered"The air archive maintained by CSIRO started in 1978, and contains samples of clean air from a station at Cape Grim, Tasmania. It’s the oldest such archive in the world. Now with Allport’s tank, last used in 1970, the record has been extended further.
The air contained traces of propellants, refrigerants and emissions form aluminium smelters. Paul Fraser, who leads CSIRO’s greenhouse gas research team says that the scuba tank is going to be really useful: “If tanks were filled in a clean coastal environment their usefulness in measuring greenhouse gases such as carbon dioxide, methane, nitrous oxide and chloro-flurocarbons (CFCs) is much broader,” he says.

The Dyche Natural History Museum at the University of Kansas has this almost hidden little room in the basement where you can go in, close a curtain, flip on a blacklight and watch as a collection of seemingly ordinary rocks light up with a fluorescent glow. This series of images, taken by photographer Louise Murray, reminds me of how much I like that room at the Dyche. Only, instead of rocks, Murray snaps photos of coral, fish and other sea creatures, using a portable blue light.
Fluorescent colours are produced by cells responding to certain wavelengths of light hitting them - causing the cell to emit its own light on a different wavelength, which creates a different colour. Traffic cones and highlighter pens are just two everyday examples of fluorescing objects that humans can detect without any equipment. Above ground people can usually pick up other fluorescing objects using ultra violet lights.

Like having a real Christmas tree, but hate having to crawl underneath it to keep it watered? Well, Andrew King has a pretty good solution. He set up a small tank of water next to the tree, then ran a hose over to it to make an xmas tree siphon. Nice and easy, and you end up with more space under the tree for presents. I think I would make mine to look like a giant water tower, to match the train that we have running under there.

Cardboard Brian* and I met at a ski shop in Colorado. He was hanging out by the front door, smiling indiscriminately at passersby. I instantly fell for his charming, goofy, lopsided grin. The shop employee said he wasn't for sale, but he let me take him home anyway.
I was drawn to Cardboard Brian because he slightly resembles my real life boyfriend — they have the exact same hairstyle and cartoon-like facial features. But shortly after I brought him back to my hotel room, I began to feel like Cardboard Brian was taking on a life of his own. While Real Brian sat at his computer chatting away on AIM with his buddies, Cardboard Brian sat next to me on the couch and we watched The Wedding Planner together, both of us with smiles on our faces. I was genuinely enjoying his company.
This past Saturday, my real boyfriend was in Pacifica all day with a surf buddy, so I decided to take Cardboard Brian out with me instead. I placed him upright on my passenger seat and off we went. My first stop was the neighborhood yarn store — I needed to get some materials for a hat I'm making for my friend's newborn. I walked into the shop, holding Cardboard Brian gingerly by the head, and spent a good half hour looking at all the beautiful textures and colors of yarn. Baby blue merino or apaca-wool blend? Knit or crochet? I found myself asking Cardboard Brian simple questions that came to mind. Maybe I'm making it up, but I feel like he advised me to crochet in baby blue merino, so I went with that.
We made a quick stop at the bank. As I stood in the teller line, a couple of guys stared at Cardboard Brian, whom I had tucked neatly underneath my armpit. Cardboard Brian just stared right back and stuck his tongue out at them.
I often drive around town with my dog Ruby in the passenger seat. Since she's always staring at me, I talk to her about the weather, my itinerary for the day, the next story I'm working on.... just day-to-day chatter that passes through my busy head. Talking to Cardboard Brian was similar to that; he's much less reactive than Ruby is, but at the end of the day, both entail talking to an activity partner that can't really talk back. Is it as engaging as talking to a real human? Not exactly. But in a way, it's more satisfying because I can let all my social barriers go — I don't have to worry about whether I'm being boring or rude. It's refreshing.
It was a beautiful afternoon, so Cardboard Brian and I decided to take the dogs to the beach. Let me rephrase: I decided we should take the dogs to the beach. Cardboard Brian just smiled agreeably. We walked idly down the shoreline, hand on head, listening to the waves break and smiling at the dogs as they galloped from one washed up chunk of seaweed to the next. We stayed like this until Real Brian showed up and asked me what I was doing carrying Cardboard Brian around at the beach. "You weren't around, so I brought him instead," I told him. We took a few pictures together — me and Cardboard Brian, Real Brian and Cardboard Brian — and left as the sun began to set.
Of course, there's a downside to having a cardboard boyfriend. Cardboard Brian doesn't like to eat — I'm a food-lover at heart, so I find it hard to relate to his apathy for the culinary arts. He doesn't have a job and probably never will, which is a big turnoff. Since we can't procreate, it's hard to imagine starting a family and spending the rest of my life with him. (Well, maybe I can spend the rest of my life with him, but I have a feeling he'd end up in the closet.) He also takes up a surprising amount of room on the bed, even though he's only 18 inches in diameter. And he's not cuddly. Also, I'd never say this to his face, but he's a bit bland. Even though he kept pretty good company for a piece of paper, I have to admit I was a little bored.
After spending an entire day with a cardboard surrogate boyfriend, I decided to retire him to the office wall as decoration. As relaxing as it was to hang out with Cardboard Brian for a day, I think I'll stick with the Real, Complicated Brian and the joys and challenges he brings... at least for now.
*Cardboard Brian is actually the mascot of a snowboarding brand called Neff.

This video helps explain how researchers keep track of whether or not California is meeting standards set by AB-32—the 2006 law that mandates a 25% reduction in greenhouse gas emissions by 2020. Scientists monitor emissions round-the-clock via towers in San Francisco and Walnut Grove, California.
Using meteorological data and computer models, the scientists trace the journey of gases collected at the towers back to the areas where the gases originated. They then estimate how much greenhouse gas comes from broad sectors of central California, even from areas that are many miles upwind of the tower. Their probability-based calculations often match existing inventories of greenhouse gas emissions. Scientists have a good handle on the major greenhouse gas culprits in a region -- such as the methane emitted by a landfill or livestock feed lot -- thanks to models that utilize economic data and other information that indicate a facility's day-to-day operations, pollution and all.
But to get a closer view, researchers recently took their measurement instruments on a flight over Sacramento and the Bay area.

The BBC's digital rights plans will wreak havoc on open source softwareThe entire DTLA system relies on the keys necessary to authenticate devices and unscramble video being kept secret, and on the rules governing the use of keys being inviolable. To that end, the DTLA "Compliance and Robustness Agreement" (presented as "Annex C" to the DTLA agreement) has a number of requirements aimed at ensuring that every DTLA-approved device is armoured against user modification. Keys must be hidden. Steps must be taken to ensure that the code running on the device isn't modified. Failure to take adequate protection against user modification will result in DTLA approval being withheld or revoked.
This is where the conflict with free/open source software arises.
Free/open source software, such as the GNU/Linux operating system that runs many set-top boxes, is created cooperatively among many programmers (thousands, in some cases). Unlike proprietary software, such as the Windows operating system or the iPhone's operating system, free software authors publish their code and allow any other programmer to examine it, make improvements to it, and publish those improvements. This has proven to be a powerful means of quickly building profitable new businesses and devices, from the TomTomGo GPSes to Google's Android phones to the Humax Freeview box you can buy tonight at Argos for around £130.
Because it can be adapted by anyone, free software is an incredible source of innovative new ideas. Because it can be used without charge, it has allowed unparalleled competition, dramatically lowering the cost of entering electronics markets. In short, free software is good for business, it's good for the public, it's good for progress, and it's good for competition.
But free software is bad for DTLA compliance.

Chad Orzel's How to Teach Physics to Your Dog is an absolutely delightful book on many axes: first, its subject matter, quantum physics, is arguably the most mind-bending scientific subject we have; second, the device of the book -- a quantum physicist, Orzel, explains quantum physics to Emmy, his cheeky German shepherd -- is a hoot, and has the singular advantage of making the mind-bending a little less traumatic when the going gets tough (quantum physics has a certain irreducible complexity that precludes an easy understanding of its implications); finally, third, it is extremely well-written, combining a scientist's rigor and accuracy with a natural raconteur's storytelling skill.
I find quantum physics very difficult to hold in my head. I can understand it while it's being explained, and sometimes for a day or two longer, but then it fizzles away (I find calculus to be of similar character). However, the essentials I've grasped have always come embedded in stories -- first in Greg Egan's magnificent debut novel Quarantine and now in How to Teach Physics to Your Dog. The going isn't always smooth or easy, but for me, it has never been less hard!

In other words, your Kindle will periodically send information about you to Amazon. But exactly what information is sent? Amazon's wording -- "information related to the content on your Device and your use of it" -- reads so broadly that it appears to allow Amazon to track all content that users put on the device, regardless of whether that content is purchased from Amazon. Some security researchers have indicated that the Kindle may even be tracking its users' GPS locations.

Attackers Buying Own Data Centers for Botnets, Spam (via /.)"It's gotten completely out of hand. The bad guys are going to some local registries in Europe and getting massive amounts of IP space and then they just go to a hosting provider and set up their own data centers," said Alex Lanstein, senior security researcher at FireEye, an antimalware and anti-botnet vendor. "It takes one more level out of it: You own your own IP space and you're your own ISP at that point.
"If there's a problem, who are you going to talk to? It's a different ball game now. These guys are buying their own data centers. These LIRs and RIRs aren't going to push back if you say you need a /24 or /16. They're not the Internet police," Lanstein said...
"This is part of the problem that's causing the IPv4 shortage," Lanstein said, referring to the imminent exhaustion of the IPv4 address space, forecasted to occur in less than two years. "They stop paying the bills, the space gets null-routed and then it's a mess. There's clear fraud going on, but who can do something about it?"

In addition to emulating the functionality of the AVR microcontrollers, it has a library that you can use to emulate peripherals, such as buttons or LED screens.

The only problem, of course, is that these ads are placed by Amazon affiliates, and any defamation claim almost certainly should fall under a Section 230 safe harbor that protects Amazon. The claims in the lawsuit that Sellify notified Amazon are meaningless. Basically, Sellify is suing the wrong party. They might have an argument if they sued the affiliates in question, but they appear to have chosen to focus instead on the big, easy target. But, the whole purpose of Section 230 is so that you can't just focus on the big, easy target, but have to sue those actually responsible.

Seems like the worst list could be miles longer. And no Google in the best list? Wikipedia and crowdsourcing?
What are your candidates for best and worst tech of the aughts?
Here's James' "Maker Culture" entry:
The Maker Culture: There's always been a DIY underground, covering everything from Ham radio to photography to model railroading. But the level of cool has taken a noticeable uptick this decade, as cheap digital technology has given DIY a kick in the pants. The Arduino lets anyone embed control capabilities into just about anything you can imagine, amateur PCB board fabrication has gone from a messy kitchen sink operation to a click-and-upload-your-design purchase, and the 3D printer is turning the Star Trek replicator into a reality.Manufacturers cringe in fear as enterprising geeks dig out their screwdrivers. The conventional wisdom was that as electronics got more complex, the "no user serviceable parts" mentality would spell the end of consumer experimentation. But instead, the fact that everything is turning into a computer meant that you could take a device meant for one thing, and reprogram it to do something else. Don't like your digital camera's software? Install your own! Turn your DVR into a Linux server.
Meanwhile, shows like Mythbusters and events like Maker Faire have shown that hacking hardware can grab the public's interest, especially if there are explosions involved.
