SolarSells writes "Solyndra makes funky-looking cylindrical solar cells that resemble compact fluorescent lightbulbs. Their products are meant for office buildings, and are made from a thin coating of copper indium gallium diselenide on glass tubes. Although they might not be able to fill them till 2012, the company has already received $1.2 billion in orders. Their manufacturing tricks make the cells so cheap that they may be competitive with other forms of power even after solar subsidies are phased out."

Wired is running a story about the small but vocal, and growing, number of people who aren't waiting for automakers to deliver plug-in hybrids. They're shelling out big money to have already thrifty cars converted into full-on plug-in hybrids capable of triple-digit fuel economy. "The conversions aren't cheap, and top-of-the-line kits with lithium-ion batteries can set you back as much as $35,000. Even a kit with lead-acid batteries — the type under the hood of the car you drive now — starts at five grand. That explains why most converted plug-ins are in the motor pools of places like Southern California Edison... No more than 150 or so belong to people like [extreme skiing champion Alison] Gannett, who had her $30,000 Ford Escape converted in December. Yes, that's right. The conversion cost more than the truck."

Wired is running a story about a case the Supreme Court will be hearing on Tuesday that relates to searches based on erroneous information in government databases. In the case of Herring vs. US 07-513, the defendant was followed and pulled over based on a records indicating he had a warrant out for his arrest. Upon further review, the local county clerk found the records were in error, and the warrant notification should have been removed months prior. Unfortunately for Herring, he had already been arrested and his car searched. Police found a small amount of drugs and a firearm, for which Herring was subsequently prosecuted. Several friend-of-the-court briefs have been filed to argue this case, some calling for "an accuracy obligation on law enforcement agents [PDF] who rely on criminal justice information systems," and others defending such searches as good-faith exceptions [PDF].

Many readers reminded us of what no-one can have failed to hear: that the Congress passed and the President signed a $700B bailout bill in an attempt to avert the meltdown of the US economy. The bill allocates $700 billion to the Treasury Department for the purchase of so-called "toxic assets" that have been weighing down Wall Street balance sheets. This isn't particularly a tech story, though tech will be affected as will virtually all parts of the economy, and not just in the US. Among the $110B in so-called pork added to the bill to sway reluctant legislators are extensions of popular tax benefits for business R&D and alternative energy, relief for the growing pool of people subject to the alternative minimum tax, and a provision raising the FDIC's ceiling of guaranteed deposits to $250,000. Some limits were also imposed on executive compensation, though it's unclear whether they will be effective.

pgn674 writes "While the Emergency Economic Stabilization Act of 2008 failed to pass in the House of Representatives, two other bills of interest to this community are currently moving through the US lawmaking process. One is the Broadband Data Improvement Act, which Communications Workers of America claims will help us towards bringing high-speed Internet access to all Americans. It will have the FCC increase their granularity in reporting the Internet accessibility of an area in the US, and redefine broadband measurements. It has passed through the House and the Senate, and differences in the passed versions are currently being resolved. The other bill is the Webcaster Settlement Act of 2008. Pandora is excited for this one as it will give them time to negotiate with SoundExchange (i.e. the RIAA) for new, more affordable royalty rates. The bill is currently in the Senate, and is expected to pass with ease."

Selikoff writes "I just noticed Cablevision's Optimum Online service has begun hijacking DNS Error pages with, you guessed it, ad-supported results. Aside from hurting the underlying stability of the Internet, there have been instances where hackers have used such tools against customers. I know Road Runner customers have had to deal with this for a couple months now, although at least they have an outlet to turn it off." Update: 09/30 13:18 GMT by T : Note, as several readers have pointed out, this hijacking is of DNS errors rather than 404 errors as originally presented.

hackingbear writes "Wired, citing a paper published in Science magazine, reports that Harvard scientists may have found a safer way of giving a flake of skin the biologically alchemical powers of embryonic stem cells by turning adult cells into versatile, embryonic-like cells without causing permanent damage. The technique involves 'adding cell-reprogramming genes to adenoviruses, a type of virus that infects cells without affecting their DNA.' Four-month trials on mice demonstrated that the resulting stem cells are free from unpredictable cancer-inducing mutations. This is definitely a breakthrough in stem cell research." Additional coverage is available at Yahoo, and Science hosts the research paper, although you'll need a subscription to see more than the abstract.

Erik J writes "Microsoft has announced that the PC version of Rockstar's Grand Theft Auto IV will exclusively use Games for Windows Live for its multiplayer mode when it hits shelves November 18th. Rockstar founder Sam Houser explained the decision: 'As we work toward the release of the PC version, Games for Windows Live affords us the opportunity to seamlessly translate the multiplayer console experience for PC gamers, the service is a natural fit for the platform and we strongly believe it will help in building a strong online community around GTA IV PC.'" Wired is running a story suggesting that this release could save the rather unpopular Microsoft PC gaming platform.

Anti-Globalism writes with this excerpt from CNet: "Google's vision of tomorrow's wireless network is in stark contrast to how wireless operators do business today, setting the two sides on a possible collision course. Earlier this week, the search giant filed a patent application with the US Patent Office describing its vision of an open wireless network where smartphones aren't tied to any single cell phone network. In Google's open wireless world, phones and other wireless devices would search for the strongest, fastest connection at the most competitive price. Essentially, wireless operators' networks would be reduced to 'dumb pipes.'" The full patent application is available as well. Google founder Larry Page recently asked the FCC to free up portions of the broadcast spectrum for this purpose.

mbone writes "Wired's David Kravets reports on a new lobbying effort to support the filtering of internet traffic called Arts & Labs. Coverage is available at PC World as well. The lobby's members include AT&T, Cisco Systems, Microsoft, NBC Universal, Viacom and the Songwriters Guild of America. Their web site says, 'network operators must have the flexibility to manage and expand their networks to defend against net pollution and illegal file-trafficking which threatens to congest and delay the network for all consumers.' Does it seem that this is an attempt to categorize P2P with spam and malware, or is it just me?"

isBandGeek() writes "After a few reasonable App Store bans, such as the ones on I Am Rich and NetShare, developers started complaining about excessive restrictions on applications like Podcaster and MailWrangler, supposedly because they provided 'duplicate functionality.' In response, Apple rubbed salt in their wounds by slapping non-disclosure agreements on application rejection notices. Now developers are not even allowed to tell their fanbase that Apple decided to withhold approval for an application. Is Apple confident that Google's open platform Android won't be much of a threat?"

I Don't Believe in Imaginary Property writes "The White House has opposed the bipartisan bill that would create copyright cops on the grounds that it would cause the Department of Justice to end up 'serving as pro bono lawyers for private copyright holders.' And while they do occasionally prosecute criminal copyright infringement, they have no intention of dabbling with civil cases because, 'taxpayer-supported department lawyers would pursue lawsuits for copyright holders, with monetary recovery going to industry.' At this rate, the discovery of winged suiformes would appear to be imminent."

jcgam69 writes "SpaceX's Falcon 1 is on the pad in the South Pacific Kwajalein Atoll ready for its fourth launch attempt, according to a blog post over the weekend from SpaceX CEO Elon Musk. The countdown is scheduled for Tuesday, Sept. 23, between 4 p.m. and 9 p.m. PDT, though the launch window will extend through Thursday if need be."

Wired reports that Comcast finally provided information on its network management practices late Friday. In a report to the FCC (PDF), the cable company admitted to targeting P2P protocols Ares, BitTorrent, eDonkey, FasTrack, and Gnutella. Quoting: "For each of the managed P2P protocols, the [Sandvine Policy Traffic Switch] monitors and identifies the number of simultaneous unidirectional uploads that are passed from the [Cable Modem Termination System] to the upstream router. Because of the prevalence of P2P traffic on the upstream portion of our network, the number of simultaneous unidirectional upload sessions of any particular P2P protocol at any given time serves as a useful proxy for determining the level of overall network congestion. For each of the protocols, a session threshold is in place that is intended to provide for equivalently fair access between the protocols, but still mitigate the likelihood of congestion that could cause service degradation for our customers."

Last week Metallica released a new album, Death Magnetic, on traditional CDs as well as downloadable content for Guitar Hero III. Fans quickly noticed that the sound quality on the CD version was noticeably below-par, thanks to the recording studio's decision to sacrifice range for loudness. However, the tracks released for Guitar Hero III made no such sacrifice, as proved by Mastering Engineer Ian Shepherd. NME found an audio clip comparing the two tracks. This comes alongside statements from Activision claiming that Aerosmith's recent venture into Guitar Hero is generating more success for the band than their actual albums.

Dozens of doctors weighed in with comments, and many of them seem to think that the wry subject is an almost useless rite of passage. Wired Science points out that there are not enough doctors who do research in addition to seeing patients, and they are the ones who benefit most from a thorough grounding in basic sciences like organic chemistry."

Note that there is no easy way to tell if the material on Wikileaks is genuine or a hoax. Update by J : Genuine.

inetstorm, who has "been a NIN fan for ages," sends along a Wired profile giving a look behind the scenes at the tech underlying the current NIN concert tour. "... this time around, NIN has pulled out all the stops, creating a groundbreaking, fully interactive visual display that is as much a part of the show as the band's instruments ... The core of the show is a sophisticated trio of transparent 'stealth' screens, which are raised and lowered during the performance... For the interactive portions of the show, all the onscreen video is rendered by Moment Factory's custom rig, a trio of Linux-based devices collectively known as 'the brain.'"

The_AV8R writes "Jonathan Zdziarski showed that every time you press the Home button on your iPhone, a screen capture is taken in order to produce a visual effect. This image is then cached and later deleted. Zdziarski says that there have been cases of law enforcement looking up sex offenders' old data and checking recovered screenshots." This revelation occurred in the midst of a webcast on iPhone forensics, demonstrating how to bypass the iPhone's password security (not trivial, but doable). Video from the talk is not online yet but is promised soon over at O'Reilly.

Wired is running a story about a research paper out of the University of Wisconsin-Madison which discusses how some games get players to do scientific research without them explicitly realizing it. The paper itself is also available. Quoting: "... we examine the scientific habits of mind and dispositions that characterize online discussion forums of the massively multiplayer online game World of Warcraft. Eighty-six percent of the forum discussions were posts engaged in 'social knowledge construction' rather than social banter. Over half of the posts evidenced systems based on reason, one in ten evidenced model-based reasoning, and 65% displayed an evaluative epistemology in which knowledge is treated as an open-ended process of evaluation and argument."

Aditya Malik writes "Wired has an interesting story up about how a lab led by Jack Szostak, a molecular biologist at Harvard Medical School, is building 'protocells' from artificial molecules which are very close to satisfying the conditions for being 'alive.' 'Szostak's protocells are built from fatty molecules that can trap bits of nucleic acids that contain the source code for replication. Combined with a process that harnesses external energy from the sun or chemical reactions, they could form a self-replicating, evolving system that satisfies the conditions of life, but isn't anything like life on earth now, but might represent life as it began or could exist elsewhere in the universe.' This obviously raises some questions about creationism, not to mention some scary bio-research-gone-wild scenarios."

angelheaded tips a Wired story about the resignation of Bob Dykes, CEO of net eavesdropping firm NebuAd. NebuAd has encountered financial troubles lately as the privacy controversy surrounding the company's tracking methods has driven communications companies away. Over in the UK, Phorm responded to the NebuAd news by affirming that it is making progress with its advertising methods. From The Register: "In response to the outcry over our revealing its two secret trials, BT said in April it would re-engineer the planned deployment so traffic to and from customers who do not want their web use profiled for marketing purposes would not come into contact with the Phorm system. The original blueprint meant that a opt-out cookie would tell the technology to simply ignore refuseniks' browsing as it passed through. It's thought the change has proved tricky. Phorm did not immediately respond to a request for comment on the alleged technical problems, but [BT's chief press officer Adam Liversage] said: 'We have been working on some things with Phorm.'"

NewYorkCountryLawyer writes "David Kravets of Wired.com, who provided in-person gavel-to-gavel coverage of the Capitol v. Thomas trial last year, takes stock of the RIAA's 5-year-old litigation campaign, concluding it is 'at a crossroads', and noting that 'billions of copies of copyrighted songs are now changing hands each year on file sharing services. All the while, some of the most fundamental legal questions surrounding the legality of file sharing have gone unanswered. Even the future of the RIAA's only jury trial victory — against Minnesota mother Jammie Thomas — is in doubt. Some are wondering if the campaign has shaped up as an utter failure.'"

Much ink and many electrons are being spilled over Google's Chrome browser (discussed here twice in recent days): from deep backgrounders to performance benchmarks to its vulnerability to a carpet-bombing flaw.

His jury trial concluded in April with Reiser's first-degree murder conviction. That carries a 25-to-life term, but the authorities, in a backroom deal, later offered him 15-to-life if he produced his wife's body and waived any rights to appeal his conviction." Several other readers contributed coverage at SFGate.

An anonymous reader writes with this snippet from Wired: "After six Nobel Prizes, the invention of the transistor, laser and countless contributions to computer science and technology, it is the end of the road for Bell Labs' fundamental physics research lab. Alcatel-Lucent, the parent company of Bell Labs, is pulling out of basic science, material physics and semiconductor research and will instead be focusing on more immediately marketable areas such as networking, high-speed electronics, wireless, nanotechnology and software." Jamie points out this list of Bell Labs' accomplishments at Wikipedia, including little things like the UNIX operating system.

I Don't Believe in Imaginary Property writes "Wikileaks seems to be a bit hard-up for cash, so they're trying a little experiment. They plan to auction off an archive with three years worth of Hugo Chavez' email. The winner will get a period of embargoed access to break any stories they can find in the files, while Wikileaks will later publish the archive in full. Wikileaks plans to use the profits for their legal defense fund, but they may run into trouble because most reputable news outlets have policies against paying sources."

At DEFCON, Tony Kapela and Alex Pilosov demonstrated a drastic weakness in the Internet's infrastructure that had long been rumored, but wasn't believed practical. They showed how to hijack BGP (the border gateway protocol) in order to eavesdrop on Net traffic in a way that wouldn't be simple to detect. Quoting: "'It's at least as big an issue as the DNS issue, if not bigger,' said Peiter 'Mudge' Zatko, noted computer security expert and former member of the L0pht hacking group, who testified to Congress in 1998 that he could bring down the internet in 30 minutes using a similar BGP attack, and disclosed privately to government agents how BGP could also be exploited to eavesdrop. 'I went around screaming my head about this about ten or twelve years ago... We described this to intelligence agencies and to the National Security Council, in detail.' The man-in-the-middle attack exploits BGP to fool routers into re-directing data to an eavesdropper's network." Here's the PDF of Kapela and Pilosov's presentation.

zentanu writes "It's said that if you want to be happy, be a gardener. What about IT security professionals? Having worked as an IT security consultant for several years, I now wonder if my job has a negative influence on my happiness, because it constantly teaches me to focus on the negative side of life: I always have to think about risks and identify all sorts of things that could go wrong. As an auditor I search for errors that others have made and haughtily tell them. As a penetration tester I break systems that system engineers and administrators have laboriously built. I assume inside threats and have to be professionally suspicious. The security mindset surely helps me in my job, but is it good for me on the long run? What kind of influence has being an IT security professional had on your general attitude towards life? What helps you stay out of pessimism and cynicism? Is protecting existing things really as good as building new ones?"

eldavojohn writes "If you like iTunes and you are one of the billion people residing in China, you may have noticed that you no longer have access to the eight million songs on it. An album, 'Songs for Tibet' was downloaded more than 40 times by Olympic athletes as a sign of solidarity for Tibet's cause. Ironically, this compilation had songs criticizing the 'Great Firewall of China,' and that is the very thing that prohibited these songs from reaching the Chinese public. Artists on the compilation include Alanis Morissette, Garbage, Imogen Heap, Moby, Sting, Suzanne Vega, Underworld and others." Additional coverage is available at Computerworld. Earlier this year, China blocked Youtube and other video services for similar reasons. More recently, the Chinese government detained a technologist who planned a pro-Tibet demonstration.

palegray.net writes "The National Center for State Courts, a nonprofit organization, has sent file-sharing propaganda to thousands of students.

I Don't Believe in Imaginary Property writes "US District Judge Jeremy Fogel has ruled that an 'allegation that a copyright owner acted in bad faith by issuing a takedown notice without proper consideration of the fair use doctrine thus is sufficient to state a misrepresentation claim,' which paves the way for a lawsuit against Universal Music over a ridiculous DMCA Takedown notice they filed. One can only hope that this ruling will some day be used against those who file misguided copyright complaints against computer printers. Those lawyers who rely upon buggy infringement detection programs to do their thinking for them — programs which are incapable of making subjective considerations like fair use — might want to think again before rubber stamping computer-generated DMCA Takedown notices."

I Don't Believe in Imaginary Property writes "According to a new ruling, those put on the No-Fly List can challenge their inclusion in federal court. Previously, they had to go directly to an appellate court, which would deprive them of any chance to subpoena documents or witnesses and make gathering evidence difficult or impossible. Knowing the government, they will get around this by creating a 'No-Sue' list and making it even harder to change your name."

longacre writes "Following in the footsteps of DARPA's Urban Challenge, in which robotic vehicles had to navigate a complex obstacle course without human intervention, the UK upped the ante with its own Ministry of Defence Grand Challenge: within a mock enemy village, robots were instructed to find potential targets and make distinctions between armed troops, roadside bombs and snipers. The winning entry, Team Stellar's SATURN system, actually consists of three vehicles: a low level drone and a tracked ground vehicle transmit reconnaissance data to a high-altitude robotic relay aircraft, which proceeds to phone that data home to a central processing center. Upon announcing the winner yesterday, MoD said they are 'carefully considering if technologies demonstrated in the final can be incorporated into future frontline kit for the Armed Forces. It is possible that the winning team will have invented a product that can be developed rapidly for the front line.'"

Kugrian writes "With over 9,000 hackers, freaks, feds, and geeks attending Defcon 16, the temporary wireless network setup there is considered the most hostile on the planet. Run by a dedicated group of volunteers known as Goons, the basement Defcon Network Operations Center is secured by means of a chain-link fence and armed guard. The 20-megabit connection, which is twice as fast as Defcon 15, runs over a point-to-point wireless link to another hotel that has point-of-presence in their basement. Wired's Threat Level blog managed to secure the first ever photo tour of the Center showing Goons, hardware and sniffer dogs." Reader TXISDude, who was at Defcon, doubts that attendance was as high as 9,000. Update: 08/13 18:14 GMT by T : Dave Bullock, the Wired photographer who shot these pictures, backs up that figure, though: "I interviewed Joe Grand, the badge designer a few weeks before the con. They ordered 8,600 total badges. They ran out of badges. There were hundreds of people with paper badges."

A reader, name withheld by request, writes "Writing in the IEEE Spectrum, James Oberg analyzes whether there was, in fact a significant risk to humans from the satellite which the US military shot down on 21 February, purportedly 'to head off the possibility of its splashing a half ton of toxic hydrazine fuel somewhere on Earth.' Previous experts had 'scoffed' at the rationale put forth, pointing out that there was trivial possibility that any significant amount of toxic fuel would make it to the ground intact. Oberg's analysis, titled 'the inside story,' purports to debunk this, and claims that indeed it's possible, and even likely, that there could be a danger to the ground. Unfortunately, the analysis is full of flaws and lack of rigor — indeed, lacking any sort of numerical reasoning. It seems to be too much repeating official 'spin,' and could have used a hefty dose of skepticism — and could also use a little bit of actual analysis using numbers, rather than handwaving." Read on for the rest of an interesting analysis of a topic that suddenly seems more complex. The submitter continues: "Here's the first number that Oberg should have quoted: 32 Megajoules per kilogram. That's orbital energy, which is how much energy has to be removed by ablation or otherwise dissipated for the hydrazine tank to enter the atmosphere and hit the ground undamaged. For reference, TNT holds about 4.6 MJ/kg. Oberg quotes 'Hydrazine requires a tremendous amount of energy to go from solid to liquid.' This energy is known as the heat of fusion, and for hydrazine it is just a little under 400 kJ/kg. That's about 1% of the energy released by entry heating. Hardly a 'tremendous' amount of energy, compared to the entry energy that's nearly a hundred times greater.

Oberg goes on to quote 'There is a widespread notion that meteorites falling to Earth arrive red hot.' He is correct here. In fact, meteorites falling through the atmosphere typically explode, shattering into dozens or hundreds of pieces; something that occurs at the point when the dynamic pressure on the leading face exceeds the yield stress of the material. This occurs for meteoroids of all compositions, including nickle-iron meteorites that are far more robust than hydrazine tanks. If the atmospheric entry of meteorites is relevant, it hardly bolsters the case that a tank will enter intact (and if it's not relevent, why did Oberg bring it up?)

Furthermore, if you look at a typical nickle-iron meteorite, you'll see a surface pitted and mottled with holes ranging from the size of golf balls up to pits the size of baseballs. These are known as regmaglypts; they are the areas ablated away by the entry plasma. Even a single such ablation pit would, of course, destroy a hydrazine tank.

The second number Oberg should have quoted is a number called ballistic coefficient, the mass divided by the area of the tank. Basically, the smaller the ballistic coefficient, the less stressful the entry will be. Unfortunately, a full hydrazine tank has a very high ballistic coefficient. It is an empty tank, not a full one, that is likely to enter intact. Talking about empty film canisters, or even empty fuel tanks, making it intact through atmospheric entry is really about as relevant as talking about dropping a piece of paper on the floor.

The article contains a quote from Andrew Higgins, with a link to (purportedly) the research done that contains the quote. Unfortunately the link does not actually contain the quote used in the article; in fact, it seems to be mostly a discussion of a side issue. Let me emphasize this: Higgins did not say what he is quoted as saying in the place he was reported as saying it. This may merely be sloppy journalism — maybe he said it somewhere else — but I am again left with the question: if I can't even trust the simplest things he says that can be easily checked, why should I trust anything else?

In short, Oberg's article is poorly thought out, avoids even simple back-of-the-envelope calculations, and accepts uncritically information that should have been aggressively questioned. He concludes that a well-defined and thoroughly researched technological hazard assessment — of a kind that someday, for better or worse, will be needed again — has wound up buried in obscurity and obfuscation. This may be true, but no well defined nor thoroughly researched technological hazard assessment was anywhere in evidence. The analysis he gives in the article is buried in obscurity and obfuscation.

AgaveNectar writes "Doctors are far from being early adopters, so they have just gotten around to publishing a report that webcams help immensely with making the right decision when someone shows up to a rural emergency room suffering from a stroke. Using clot-destroying medications like Alteplase is really risky, and it should only be given in acute cases. In a study of 222 patients, rural ER doctors consulted with faraway stroke specialists. They made the right decision 98 percent of the time when the expert examined the patient with a webcam, and only 82 percent of the time when they just talked to each other on the phone. Perhaps this report will finally convince the medical community that telemedicine is important."

InflammatoryHeadlineGuy writes "What do Shrinky Dinks, credit cards and paperclips have in common? They can all be used to duplicate the keys to Medeco 'high-security' locks that protect the White House, the Pentagon, embassies, and many other sensitive locations. The attack was demonstrated at Defcon by Marc Weber Tobias and involves getting a picture of the key, then printing it out and cutting plastic to match — both credit cards and Shrinky Dinks plastic are recommended. The paperclip then pushes aside a slider deep in the keyway, while the plastic cut-out lifts the pins. They were able to open an example lock in about six seconds. The only solution seems to be to ensure that your security systems are layered, so that attackers are stopped by other means even if they manage to duplicate your keys."

But the Iraq and Afghanistan wars have become so dependent on the robo-planes that the Air Force has called in chaplains and psychiatrists to help these remote-control warriors cope.

Aimar, who is commander of the 163d Reconnaissance Wing here and has a bachelor's degree in psychology. But when a Predator fires a missile, "you watch it all the way to impact, and I mean it's very vivid, it's right there and personal. So it does stay in people's minds for a long time."'"

This was due to a timing problem, when their brand-new engine design produced residual thrust for 1.5 seconds longer than expected; they're currently working to fix the problem and launch again, perhaps as early as next month. In a recent interview with Wired, SpaceX CEO Elon Musk remarked on their efforts: "Optimism, pessimism, f-ck that; we're going to make it happen. As God is my bloody witness, I'm hell-bent on making it work.""

NewYorkCountryLawyer writes "Apparently the RIAA's 'big gun' didn't fare so well this morning in Duluth, when he tried to persuade the judge in Capitol v. Thomas that the part of the Copyright Act which says 'by sale or other transfer of ownership, or by rental, lease, or lending', can be disregarded. According to an in-person account by Wired.com the Judge indicated that he is likely to grant a mistrial, setting aside the $222,000 jury verdict based upon his incorrect jury instruction, and that he will probably hand down his decision in September. Just yesterday some of the same lawyers got rebuffed by the US Court of Appeals for the Second Circuit in their attempt to argue that Cablevision's online storage for its customers constitutes a copyright infringement, in Cartoon Network v. CSC Holdings. There, too, the content owners had argued that the wording of the Copyright Act did not mean what it said. There, too, the Court politely but firmly disagreed."

Various gadget/toy venues are writing about the Toyota Winglet, a diminutive Segway-like personal transporter. (Toyota took over Sony's robot division a year back.) It comes in three sizes and offers about a third the speed and a quarter the range of the Segway; on the upside, it charges in an hour vs. Segway's 10 hours. Wired writes: "The Winglet is the first gadget to duplicate the celebrated, and often mocked, navigation system of the Segway Transporter."

ElonVonBraun writes "The web is abuzz with rumors that SpaceX will attempt its third rocket launch today. In the past two days, they have also done successful tests of their bigger, stronger rockets. When the launch does happen, sometime during this five-day window, there will be a webcast. Betting odds are that they will do it around 4PM PST."
