Barence writes "A new visual search engine could help photographers keep track of their photographs whenever, and wherever, they appear on the internet. The TinEye search engine allows users to search by uploading a picture rather than typing in a keyword. It then conducts a pixel-by-pixel search across the internet, flagging all instances of that image even if it's been cropped, merged or digitally altered in some way. It's not just for copyright enforcement though; 'it's being used by researchers who need to find where an image came from to provide attribution, even people who are trying to find out who people are in old photos.' It's currently in beta, but you can try it out."

MetaPhyzx writes "According to an article put forth by the Toward Freedom website, the metallic ore known as columbite-tantalite or coltan for short is fueling conflict in central Africa. The relevance to us who read news for geeks: Coltan is in quite a few consumer electronics; the article references the Sony Playstation series." As reader fahrvergnugen points out in the comments below, there's reason to more than doubt the currency of the claims in the above-linked article, as outlined in a post at Joystiq.

theodp writes "If you thought gas prices were rising too quickly, writes CNET's Marguerite Reardon, check out what's been happening to text messaging. Since 2005, rates to send and receive text messages on all four major carrier networks have doubled from 10 cents to 20 cents per message. If the same pricing was applied on a per-byte basis to a single MP3 song download, it would set you back almost $24,000 according to one estimate. So why are carriers gouging their customers so? Because they can, concludes Reardon."

I Don't Believe in Imaginary Property writes "Members of this community may want to venture out of the basement more often, because Dr. Harald Dobnig and his team have found that vitamin D deficiency leads to increased mortality. These results still hold when they take into account such factors as exercise and heart disease. Low vitamin D status has 'other significant negative effects in terms of incidence of cancer, stroke, sudden cardiac death and death of heart failure,' Dr. Dobnig said. The evidence of ill effects from low vitamin D 'is just becoming overwhelming at this point.' Vitamin D3 is usually produced by exposure to the UV-B in sunlight, but in high latitudes, especially in the fall and winter, insufficient UV-B gets through the atmosphere to produce enough vitamin D3, even with hours of exposure. The researchers are recommending that people at risk for deficiency take 800 IU of vitamin D3 daily. Just don't go overboard — as a fat-soluble vitamin, D3 is more capable of causing adverse effects at unnaturally high dosages. The human body tops out at producing about 10,000 IU per day." According to the Wikipedia entry linked above, the D2 (ergocalciferol) version -- available as a vegan product -- works approximately as well to supply humans with their needed vitamin D.

labourstart writes "Meetup.com wasn't designed to help presidential candidates and Twitter wasn't supposed to be a campaigning tool. But LabourStart's Eric Lee argues that Twitter may be just what unions and other campaigning organizations have been looking for — a way to cut through the background noise and reach their members."

snydeq writes "InfoWorld's Tom Yager offers insight on how digital TV is rapidly heading toward the kind of lockdown that entertainment and broadcast lobbies desire for the Internet. Standards such as HDMI and HDCP are acting in concert to strip your equipment of its functionality, displaying 'incompatibility' messages when plugged into older HDMI-enabled devices, shutting down analog outputs when active, and requiring balky handshake credentials that force many consumers to reboot their TVs to recover permission to watch them. Even broadcast flagging, which has been overturned by the Court of Appeals, is still on the de-facto table, as the entertainment lobby retains the power to bully technology companies into baking broadcast flagging into their wares. Sure, digital TV has far fewer points of origin than the Internet and is therefore easier to control, but, as Yager writes, 'Internet rights restrictions come through your telecommunications equipment' — and it is likely through that equipment that the entertainment and broadcast lobbies will chip away at your rights on the Web."

michaelrash writes "The Google Trends project provides some visibility into how popular search terms like 'Myspace' or '2008 Election' change over time and points out relevant news articles that create jumps in search volume. This is a handy tool, but there are many search terms that Google Trends does not display any results for. Such terms (such as 'Linux Firewalls' — with the quotes) have insufficient search volumes to display graphs according to the error message that Google Trends generates. Fair enough. Google sets an internal threshold on search volume, and this threshold could be set for reasons that range anywhere from Google Trends is still experimental to Google not wanting to provide data on how it builds its massive search index for emerging search terms. Either way, I would like a way to see search term trends that Google doesn't currently make available to me. So, I've released an open source project called 'Gootrude' to do just this. For the past year Gootrude has collected a set of low-volume search terms and interfaced with Gnuplot to visualize them."

esocid writes "The sun has been laying low for the past couple of years, producing no sunspots and giving a break to satellites. Periods of inactivity are normal for the sun, but this period has gone on longer than usual. The sun usually operates on an 11-year cycle with maximum activity occurring in the middle of the cycle. The last cycle reached its peak in 2001 and is believed to be just ending now, with the next cycle just beginning and expected to reach its peak sometime around 2012. Today's sun, however, is as inactive as it was two years ago, and scientists aren't sure why. In the past, solar physicists observed that the sun once went 50 years without producing sunspots, coinciding with a little ice age on Earth that lasted from 1650 to 1700." (More below.)

Gordonjcp writes "A renowned racing car designer has said that car manufacturers should be looking at making cars lighter to improve efficiency, rather than adding complex drive trains. In this article on the BBC News website, Professor Gordon Murray explains that a weight saving of 10% in a normal car would make more difference than switching to a hybrid engine and motor combination. Could this be the next nail in the SUV's coffin?"

Aire Libre and other readers noted a unanimous Supreme Court decision that denied LG Electronics's attempt to evade the first-sale doctrine by use of "business method" patents. LG licensed patents to Intel, then attempted to dictate what use Intel's customers could make of the Intel products incorporating LG patents. The decision (PDF) notes how easily patents can be written up as "business methods" to nullify the first-sale doctrine ("exhaustion") and to give the patent owner perpetual control downstream. Aire Libre adds, "That reasoning bodes well for copyright freedom as well, in light of the growing number of copyright holders who seek to nullify the Copyright Act's limitation on the distribution right by claiming the goods are 'licensed, not sold,' or subject to some restrictive EULA."

Kotaku has a great writeup on some of their gamplay impressions from the new game, Dark Void. "Dark Void is basically Crimson Skies with on-foot combat. That may be overgeneralizing things, but Ed Fries co-founder at Airtight Games and former Microsoft Game Studios guy essentially pitched the game as such at Capcom's Captivate 08 event as the type of game that the team wanted to make. With a mechanic the studio is referring to as "vertical cover combat," Dark Void looks to distinguish itself from the 3D action game crowd by way of Crimson Skies know-how and a sci-fi mythology that pits man against alien invader, selectively borrowing from classic science fiction properties in intelligent places."

Roland Piquepaille writes "An international team of scientists has found a strange ring around a dead star by using images taken by NASA's Spitzer space telescope. This star, called SGR 1900+14, belongs to a class of objects known as magnetars. According to NASA, a magnetar is 'a highly magnetized neutron star and the remnant of a brilliant supernova explosion signaling the death throes of a massive star.' So far, about a dozen magnetars have been found. An amazing thing about these stellar objects is their magnetic field. One of the researchers said that 'magnetars possess magnetic fields a million billion times stronger than the magnetic field of the Earth.'

Johannes Eva writes "As IBM Lotus Symphony shows its first public version 1.0, the Chinese OpenOffice.org derivative RedOffice offers the first beta of its new version 4.0. The open source RedOffice gets a new UI inspired from Microsoft Office 2007, with a vertical 'ribbon.' Is this the future of OpenOffice.org?"

An anonymous reader writes "What's worse than a padlocking every song so that they will only play on certain devices? How about selling (renting) you songs that work on no devices? Astonishingly, this is what the music industry thinks we need. Warner Music is spending $20 million to back Lala, a startup devising a service to convince people to 'buy' 'web songs' for 10 cents each; these are then kept for safekeeping only by Lala with no download privileges. Industry insider Michael Robertson leaks the facts on this scheme, along with a seekrit URL so you can try it out."

CNet is reporting that one blogger has started an outcry about harassment as it applies to Twitter. While their written stance appears to support the safeguarding of abuse, Twitter appears to be waffling on the issue when it comes to the hard line of enforcement. "The final response to Waldman's complaint from Twitter co-founder Biz Stone asserted that "Twitter is a communication utility, not a mediator of content," and that "Twitter recognizes that it is not skilled at judging content disputes between individuals. Determining the line between update and insult is not something that Twitter, nor a crowd, would do well. Stone added that Twitter's team would continue talking about which situations were appropriate for account banning."
