judgecorp writes "A new vendor group has promised a Gigabit wireless specification by the end of this year. The Wireless Gigabit (WiGig) spec is apparently 80 percent done and, since it is aimed at high-definition TV, it has to go at more than 3Gbps. There's around 7GHz of spectrum freely available in the 60GHz band, so it's technically feasible, and with all the major Wi-Fi silicon vendors on board (as well as Microsoft, Dell, Nokia and others) WiGig looks to have the political muscle too. They should be aware of the Sibeam-led WirelessHD group, though, already in the 60GHz space, and Ultrawideband (UWB) is not dead, as there are actual, real UWB products."

CWmike writes "Apple customers, unhappy that the company dropped FireWire from its new MacBook (not the Pro), are venting their frustrations on the company's support forum in hundreds of messages. Within minutes of Apple CEO Steve Jobs wrapping up a launch event in Cupertino, Calif., users started several threads to vent over the omission. 'Apple really screwed up with no FireWire port,' said Russ Tolman, who inaugurated a thread that by Thursday has collected more than 300 messages and been viewed over 8,000 times. 'No MacBook with [FireWire] — no new MacBook for me,' added Simon Meyer in a message posted yesterday. Several mentioned that FireWire's disappearance means that the new MacBooks could not be connected to other Macs using Target Disk Mode, and one noted that iMovie will have no way to connect to new MacBooks. Others pointed out that the previous-generation MacBook, which Apple is still selling at a reduced price of $999, includes a FireWire port. Apple introduced FireWire into its product lines in 1999 and championed the standard."

An anonymous reader writes "China is aiming to produce the world's fastest operating conventional train for its new high speed rail link between Shanghai and Beijing, achieving speeds up to 380 km/h and cutting the travel time between the two cities from the current ten hours to under five. The new rail link is scheduled to be completed within four years. Meanwhile, the Ministry of Railways' Deputy Chief Engineer has announced that China will be able to manufacture the new trains within two years."

An anonymous reader points out a story in The Register by Opera Software CTO Hakon Lie which tells the story of how Microsoft's interoperability promise for IE8 seems to have been broken in less than six months. Quoting: "In March, Microsoft announced that their upcoming Internet Explorer 8 would: use its most standards compliant mode, IE8 Standards, as the default. Note the last word: default. Microsoft argued that, in light of their newly published interoperability principles, it was the right thing to do. This declaration heralded an about-face and was widely praised by the web standards community; people were stunned and delighted by Microsoft's promise. This week, the promise was broken."

Could someone please send this kid some friggin' wheels?

Ifandbut was one of several readers to point out the arrival in Oshkosh of the first practical jetpack. It was invented by a New Zealander Glenn Martin, who has been working on the idea for 27 years. He plans to sell the gizmos for somewhere in the neighborhood of $100K. While previous attempts at jetpacks have flown for at most a couple of minutes, Mr. Martin's invention can stay aloft for half an hour. Both "practical" and "jetpack" may need quotation marks, however: The device is huge and it's incredibly noisy. And, "It is also not, to put it bluntly, a jet. 'If you're very pedantic,' Mr. Martin acknowledged, a gasoline-powered piston engine runs the large rotors. Jet Skis, he pointed out, are not jets, and the atmospheric jet stream is not created by engines. 'This thing flies on a jet of air,' he said. Or, more simply, it flies."

An anonymous reader writes "Gizmodo and Filmstalker are showing the Tron 2 (aka Tr2n) teaser from Comic-Con 08. From the Giz article: 'It's a tiny bootleg video, but I don't care. You can see that the 3D looks amazing, the new lightcycles are stunning (and move like real bikes), the world and the whole mood is Batman-like dark. And Jeff Bridges ... well, he is Jeff Bridges. What can I say, he looks like a badass version of The Dude. "It's just a game!" he shouts. No, it's not. It's Tr2n. At last. Note: excuse the excitement, but I saw the original in the movie theater, and 200 times after that. With War Games, it's what got me into technology when I was a kid, and ultimately here in Giz. The only thing that has me worried is that the characters in the computer world are fully 3D.'"

sciencehabit writes "For anyone who still believes that boys are better at math than girls, a massive new study published today in Science shows there's no difference. 'Among students with the highest test scores, the team did find that white boys outnumbered white girls by about two to one. Among Asians, however, that result was nearly reversed. Hyde says that suggests that cultural and social factors, not gender alone, influence how well students perform on tests.' But the researchers do note a disturbing trend towards omitting harder kinds of math questions from standardized tests."

Many readers are sending in word that Randy Pausch has died at 47. The charismatic young college professor celebrated life despite a death sentence from pancreatic cancer in a remarkable speech widely known as the "Last Lecture." The video went viral and has been downloaded by over 10 million people.

Brian Jordan and other readers sent in word that Google has taken the wraps off Knol, its expert-written challenger to Wikipedia. (We discussed Knol when it was announced last year.) Wired has an in-depth look. Knol's distinctions from Wikipedia are that authors are identified by their real names (and verified), and that they can share in ad revenue if they choose to. The service initially features a lot of medical articles, which is interesting considering that Medipedia also launched today. This medical wiki is backed by Harvard's and Stanford's medical schools.

dch24 was one of many who noted that the iPhone 2.0 software has already been unlocked writes "If you were wondering how I was doing push email tests on iPhone OS 2.0 and Vodafone UK, this is the reason why. The code wizard commandos at the iPhone Dev Team have been working on this non-stop since the early days of beta testing. In fact, I had iPhone OS 2.0 running on my iPhone since last week. That was version 5A345, two below 5A347, but identical in functionality." Still no word on an iPhone 3G crack.

With the launch of Apple's brand-spanking-new 3G iPhone today, Engadget has a great review of the product and many of the prominent features. The review has quite a few good pictures and is not shy about technical details, but I guess they would know a fair bit about it, having ripped one apart yesterday. "The wireless industry is a notoriously tough nut to crack, and it's become pretty clear that the first iPhone wasn't about total domination so much as priming the market and making a good first impression with some very dissatisfied cellphone users. With the iPhone 3G, though, Apple's playing for keeps. Not only is this iPhone's Exchange enterprise support aiming straight for the heart of the business market, but the long-awaited 3rd party application support and App Store means it's no longer just a device, but a viable computing platform. And its 3G network compatibility finally makes the iPhone welcome the world over, especially after Cupertino decided to ditch its non-traditional carrier partnerships in favor of dropping the handset price dramatically. $200? We're still a little stunned." Update 17:17 GMT by SM: The guys over at Engadget also pointed out that Apple is having some severe problems with their iTunes servers and many customer are being sent home without their sync complete for new iPhones.

Now.Imperfect writes "In its last day of session, the Supreme Court has definitively clarified the meaning of the Second Amendment. The confusion is whether the Second Amendment allows merely for the existence of a state militia, or the private ownership of guns. This ruling is in response to a case regarding the 32-year-old Washington DC ban on guns." This is one of the most-watched Supreme Court cases in a long time, and Wikipedia's page on the case gives a good overview; the actual text of the decision (PDF) runs to 157 pages, but the holding is summarized in the first three. There are certainly other aspects of the Second Amendment left unaddressed, however, so you can't go straight to the store for a recently made automatic rifle.
