Greatest Task of Web 2.x: Meta-Validation 161

CexpTretical writes "This Technology Review article about Web 2.x problems fails to mention the 800 pound gorilla in the room when it comes to fulfilling the dreams of the Semantic Web — i.e., assumptions about the validity of metadata or tagging schemes. We can add all of the metadata and/or tags we want to web resources but that does not mean that the 'data about the data' honestly or accurately describe the resource or are 'about the data' at all. This is why Google does not place much importance on the metadata already contained in HTML document headers for search ranking, because it cannot be trusted. And to validate it would require more effort than to search and index that data from scratch. Ensuring or verifying the validity of metadata would be a task equal to that of initially creating it, but would have to be repeated on an ongoing basis. Hence all of the talk about 'trusted networks,' which then require trusting the gatekeepers of those networks. Talk about 'semantics.'" Slashdot's moderation and meta-moderation offer one example of getting useful metadata in a non-trusted environment.

Firefox 2.0 Wins Phishfight Against IE7 181

An anonymous reader writes "A new study that pitted the anti-phishing technology in Firefox 2.0 against that of IE7 generated some interesting results. From the Washingtonpost.com story: 'Firefox blocked 243 phishing sites that IE7 overlooked, while IE7 locked 117 sites that Firefox did not.' Microsoft responded by pointing to its own supposed comparison study that put it in front of Mozilla and others in phish fighting, but the story notes: '3Sharp, the company that authored the Microsoft study, clearly state on their site that their goal in creating 3Sharp was "to use the robustness, flexibility, and sheer native capabilities of the Microsoft communication and collaboration technologies to enhance the business of our customers."'"

Did Humans Get Their Big Brains From Neanderthals? 579

MCTFB writes, "According to CNN, human beings may have acquired a gene for developing bigger brains from Neanderthal man. Apparently, 70% of the world's population has a variant of a gene regulating brain size, with this variant being most common in people of European descent (where Neanderthal man lived alongside ancient humans), and least common in people of African descent (where Neanderthal man was non-existent). While modern day eugenicists might all too eagerly read into these findings to draw their own politically biased conclusions, people such as myself, who happen to be of northern European ancestry, may find it fascinating that somewhere in our lineage ancient humans and Neanderthals decided to make love and not war on the ancient plains of Eurasia."

HomePNA Achieves 320Mbps With Copper 114

illeism writes "Ars Techinca is reporting that the HPNA has made a significant stride in copper speed. From the article: 'The HomePNA Alliance, backers of a networking spec that works over coaxial or twisted pair wiring, has announced the release of the HPNA 3.1 specification. The big news comes in the form of a speed jump from 128Mbps to 320Mbps, which pushes it above competing networking standards HomePlug AV and MoCA (Multimedia over Coax) for the title of fastest networking tech outside of gigabit Ethernet and makes it a more attractive option for triple-play providers.'"

Rumsfeld Stepping Down 899

The Ruby Way 81

Tim Hunter writes "Hal Fulton's The Ruby Way, Second Edition doesn't try to be the only book a Ruby programmer needs. It tries to be a book every serious Ruby programmer needs, and it succeeds. The Ruby Way is a book about programming with Ruby, the object-oriented programming language from Japan. Ruby is free software and runs on Linux, Microsoft Windows, Apple OS X, and other operating systems. It is available for download from its web site, www.ruby-lang.org or its companion site www.rubyforge.org. Read the rest of Tim's review.

Global Warming Debunked? 1120

limbicsystem writes, "I'm a scientist. I like Al Gore. I donate to the Sierra club, I bicycle everywhere and I eat granola. And I just read a very convincing article in the UK Telegraph that makes me think that the 'scientific consensus' on global warming is more than a little shaky. Now IANACS (I am not a climate scientist). And the Telegraph is notoriously reactionary. Can anyone out there go through this piece and tell me why it might be wrong? Because it seems to be solid, well researched, and somewhat damning of a host of authorities (the UN, the editors of Nature, the Canadian Government) who seem to have picked a side in the global warming debate without looking at the evidence." The author of the Telegraph piece is Christopher Monckton, a retired journalist and former policy advisor to Margaret Thatcher.

Melting Arctic Ice Has Consequences 466

OriginalArlen writes to tell us about some compelling global warming coverage in the Washington Post. First there is an article about a study indicating that melting Arctic ice is threatening polar bears with extinction. The article quotes an environmentalist: "This study is the smoking gun. Skeptics, polluting industries and President Bush can't run away from this one." And the polar melting is opening new shipping lanes. The second article details a trip late in October through the Northwest Passage by a Canadian icebreaker. Never before in history could this trip have been accomplished so late in the year; ice would have choked off the passage. Estimates of when the passage might be navigable by commercial shipping range from 2020 to the end of the century. The indigeneous people are not looking forward to this development.

How Steve Jobs Got Green Overnight 194

Francois writes "At Apple's last special event, Steve Jobs insisted on how environment friendly Apple's new iPod packagings are supposed to be. I don't think he's ever gone that route before. 'We've got some new packagings for the new Nano as well. And it's 52% less volume. This turns out to be an environmentally great thing. Because it dramatically reduces the amount of fossil fuels we have to spend to move these things around the planet.' Not only is it obvious they shrank the packaging to reduce the cost of shipping around the planet and sell lower than the Zune, but furthermore: there's a reason why he insisted that much, and it's not so very nice."
