adaviel sends a link to work out of Yahoo Research indicating that demographics can help Web searches; e.g. a women searching for "wagner" probably wants the 18th-century German composer, while for men in the US "wagner" is a paint sprayer. The Yahoo researchers claim that by taking user demographics into account, "they managed to get the chosen link to appear as the top-ranked result 7 per cent more often than in the standard Yahoo search." New Scientist mentions this research and two other innovative adjuncts to current search practice: following the mouse cursor as a proxy for eye tracking, and taking back bearings on online criminals by studying the searches they make. (The latter raises disburbing privacy questions: would you want Google trolling through your search data? How about governments?)

An anonymous reader writes "Moscow State University's Graphics and Media lab have released their sixth MPEG-4 AVC/H.264 video codecs comparison. Also of note is a recently added appendix to the report which compares VP8, x264, and Xvid. The reference VP8 encoder holds its own against x264 despite the source material offering x264 a slight advantage. The VP8 developers comment in the report: 'We've been following the MSU tests since they began and respect the group's work. One issue we noticed in the test is that most input sequences were previously compressed using other codecs. These sequences have an inherent bias against VP8 in recompression tests. As pointed out by other developers, H.264 and MPEG-like encoders have slight advantages in reproducing some of their own typical artifacts, which helps their objective measurement numbers but not necessarily visual quality. This is reflected by relatively better results for VP8 on the only uncompressed input sequence, "mobile calendar."'"

teh31337one writes "Four short months after Opera 10.50, the latest version of Opera's lightweight web browser has been released. It not only claims to be the fastest browser, but also the first final browser with WebM video support. It's available for Windows, Mac and Linux." Update: 07/04 21:53 GMT by T : Headline updated to reflect that this is Opera 10.60, rather than 10.6. Thanks to the readers who spotted this goof.

An anonymous reader sends in a mathematical puzzle introduced at the recent Gathering 4 Gardner, a convention of mathematicians, magicians, and puzzle enthusiasts held biannually in Atlanta. The Tuesday Birthday Problem is simply stated, but tends to mislead both intuitive and mathematically informed guesses. "I have two children, one of whom is a boy born on a Tuesday. What's the probability that my other child is a boy?" The submitter adds, "Believe it or not, the Tuesday thing is relevant. Well, sort of. It's ambiguous."

Trailrunner7 writes "The remote-wipe capability that Google recently invoked to remove a harmless application from some Android phones isn't the only remote control feature that the company built into its mobile OS. It turns out that Android also includes a feature that enables Google to remotely install apps on users' phones as well. Jon Oberheide, the security researcher who developed the application that Google remotely removed from Android phones, noticed during his research that the Android OS includes a feature called INSTALL_ASSET that allows Google to remotely install applications on users' phones. 'I don't know what design decision they based that on. Maybe they just figured since they had the removal mechanism, it's easy to have the install mechanism too,' Oberheide said in an interview. 'I don't know if they've used it yet.'"

DragonHawk writes "Mozilla Firefox 3.6.4 went to general release today. The big new feature in this release is out-of-process plugins (OOPP). This means things like Flash, Java, QuickTime, etc., all run in separate processes, so when Flash decides to crash, it won't take your browser out with it. If Flash starts consuming all the CPU it can find, you can kill it without nuking your browser session. I've been using this feature since it was in the 'nightly build' stage, and it was still more stable than 3.6.3, just because Flash was isolated." And reader Trailrunner7 supplies another compelling reason to download 3.6.4: "Security researcher Michal Zalewski has identified a problem with the way Firefox handles links that are opened in a new browser window or tab, enabling attackers to inject arbitrary code into the new window or tab while still keeping a deceptive URL in the browser's address bar. The vulnerability, which Mozilla has fixed in version 3.6.4, has the effect of tricking users into thinking that they're visiting a legitimate site while instead sending arbitrary attacker-controlled code to their browsers."

Presto Vivace sends in a report from David Pogue at the New York Times, who learned from a Verizon customer service representative that the company has implemented a policy of punishing employees who suggest certain service blocks to customers looking to avoid unwanted or accidental fees. According to the representative, offering (for example) a web access block or premium SMS block without the customer asking for it can now lead to a reprimand or outright termination. The CSRs have also been directed to avoid issuing credits for such charges. "Essentially, we are to upsell customers on the $9.99 25mb/month or $29.99 unlimited packages for customers. Customers are not to be credited for charges unless they ask for the credit. And in cases such as data or premium SMS, where the occurrences may have gone months without the consumer noticing, only an initial credit can be issued."

Calopteryx writes "New Scientist has a story on a self-replicating entity which inhabits the mathematical universe known as the Game of Life. 'Dubbed Gemini, [Andrew Wade's] creature is made of two sets of identical structures, which sit at either end of the instruction tape. Each is a fraction of the size of the tape's length but, made up of two constructor arms and one "destructor," play a key role. Gemini's initial state contains three of these structures, plus a fourth that is incomplete. As the simulation progresses the incomplete structure begins to grow, while the structure at the start of the tape is demolished. The original Gemini continues to disassemble as the new one emerges, until after nearly 34 million generations, new life is born.'"

From James Randi's blog comes word that science writer Martin Gardner has died at the age of 95. I never met Gardner, but one of his books (Entertaining Science Experiments With Everyday Objects) has been a favorite of mine since I was 6 or 7 years old; I didn't realize until just now quite how many books he authored.

Kilrah_il and several other readers made sure we noted Google's tribute to PAC-MAN on its 30th anniversary — a playable game implemented in JavaScript. "'To play the game, go to google.com during the next 48 hours (because it's too cool to keep for just one day) and either press the "Insert Coin" button or just wait for a few seconds.' There is also an Easter egg for those who want to recall one of the first multi-player games, but you'll have to RTFA to find it." This doodle may overshadow the Official PAC-MAN 30th Anniversary Destination.

bluetoad writes "Australian customs officers have been given the power to search incoming travelers' laptops and mobile phones for porn. Passengers must declare whether they are carrying pornography on their Incoming Passenger Card. The Australian government is also planning to implement an Internet filter. Once these powers are in places, who knows how they will be used."

Julie188 writes "Some 2,000 licenses cover the 230,000+ projects in Black Duck's open source knowledge base. While 10 licenses comprise 93% of the software, that leaves 1,980-odd licenses for the other 3% — and some of them have really crazy conditions. The Death and Repudiation License, for instance, requires the user to be dead."

A British website called crabrevenge.com will help you prove that there is literally nothing you can't find online by selling you pubic lice. A disclaimer on the site says the creators "do not endorse giving people lice," and the lice are for "novelty purposes only." The company also boasts about a facility "where we do all of our parasite husbandry and carefully considered selective breeding." Three different packages are available: "Green package - One colony that can lay as many as 30 eggs for about $20. Blue package - Three colonies to share with your friends or freeze a batch or two for about $35. Red package - A vial of 'shampoo-resistant F-strain crabs' which can take up to two weeks to kill for about $52."

eldavojohn writes "GamePolitics reports that South Korea's Ministry of Culture, Sports, and Tourism has announced two new policies that will force underage gamers to pick a six-hour block of time (midnight-6 AM,1-7 AM, or 2-8 AM) where they will not be able to play 19 online role-playing games. While it targets most popular MMORPGs, some popular games like Lineage were left off the list."
