When you consider the complexity of modern day web pages, it’s actually a bit of a miracle that search engines work as well as they do. Dealing with duplicate links, especially off pages such as Amazon that may promote an individual product a thousand times or more has always been a challenge. Finally, after years of debate, Google, Yahoo and Microsoft are putting the past behind them to solve this age old issue. The solution is a simple tag that will be added to the standard link format called “canonical”.
The tag is designed to solve issues associated with multiple URL’s pointing to the same page, but may also be helpful when multiple versions of a page exist. Currently, the search engines employ a process that looks at the structure of URL’s to look for similarities. This generally works pretty well, but is far from perfect. It is considered to be somewhat rare for search engines to come together on any issue, but it isn’t unprecedented. In 2006 they joined forces to put unanimous support behind sitemaps.org, and in June of 2008 they jointly announced new standards for the robots.txt directive. Matt Cutts of Google and Nathan Buggia of Microsoft claim this new approach should help reduce the clutter on the web, and improve the accuracy of all search engines.
Even though these tags won’t completely solve all the duplicate problems found on the web, it should significantly enhance the indexing performance of search engines, particularly on e-commerce sites. The new tags will be discussed in depth at this year’s Ask the Search Engines panel at SMX West.
Gigabit Ethernet may still outrun all but the most extreme SSD Raid configurations, but researchers can never rest on their laurels. Always hoping to invent the next big thing, scientists now have their sights set on Terabit Ethernet to help quell our insatiable hunger for bandwidth. A team from Australia, Denmark, and China has combined their efforts to demonstrate terabit-per-second speeds using fiber optic cables, laser light, and an unusual material named chalcogenide.
The group documented the results of its most recent trial in a white paper published in the February 16th 2009 issue of Optics Express. Though the technology is promising, Ben Eggleton, research director for CUDOS (Center for Ultrahigh bandwidth Devices for Optical Systems), points out the current limitations. “The problem isn't injecting that much high speed data into an optical strand, called multiplexing, but retrieving data at such high rates”. Conventional electronics are capable of injecting dozens of 10 Gbps streams, but trying to retrieve these streams any faster than 40 Gbps is beyond our current capabilities.
The breakthrough here however isn’t in the speed itself, but in proving the concept.Until the processing hardware catches up with our transmission capabilities, you won’t be finding this in routers anytime soon. Eggleton speculates that these concepts can be adapted to achieve slower and more manageable results, but the goal of this experiment was simply to prove that it was possible using fully photonic chips built using the same methods employed by current CMOS circuits. "It's years to complete," Eggleton said, taking these research efforts into a production technology. But these demonstrations "are starting to establish this is a serious proposition."
It is a disgrace that humans haven’t still got the hang of setting passwords. It seems as though that most internet users have inextricably tethered themselves to a promise of not setting strong-enough passwords, which may force hackers to reconsider their choice of profession for its grueling nature. As you devour more of this story, you will begin to envy hackers for having it stroll-in-the-park easy.
A new study has revealed – rather reiterated - that internet users nonchalantly continue to set unimaginative, fatuous passwords. The study appraised 28,000 passwords that were recently stolen from a U.S website.
Sixteen percent of the users had set their first name as their password. Around fourteen percent chose easiest to recall key combinations, including “1234” and “12345678”. Other users, who apparently don’t rate their mathematical ability highly, chose to steer clear of numbers and settled for passwords such as “AZERTY” and “QWERTY”.
Five percent of the passwords were found to be inspired by popular things and celebrities, including names of movies, TV shows and actors. The strongest password in this category was found to be “Ironman” as it sounds impenetrable.
Three percent of the people reckon passwords are another medium of expression. How else would you explain passwords like “Iloveyou” and “Ihateyou?”
Downloading Youtube videos has been a piece of cake for quite sometime now, though Youtube never expressly gave its assent to downloading until last month, when it made it possible for users to download videos from Barack Obama’s Youtube channel. As it turns out now, the company was just testing waters by allowing Obama’s videos to be downloaded.
Now, the video sharing website has formally approved downloading. Not all videos will be free to download, however, as users will have to pay a fee to download some of the videos. Youtube is testing an option that will let video publishers make their content available offline for free or for a price they deem fit. All payments will be processed by Youtube’s cognate company Google Checkout.
It is strange that Youtube expects users will actually be interested in paying for videos when they can be download for free through the large number of online tools available for that purpose.
Dressed for success, LG this week announced a new flagship notebook in its XNote series, the LG XNote 510. Sporting an LED backlit 15.4-inch 1,440 x 900 LCD display, the new notebook comes configurable with three different Intel Core 2 Duo processors.
The XNote P510-UP88K brings an Intel Core 2 Duo P8700 (2.53GHz, 3MB, 1066MHz frontside bus) to the table, while also serving up 2GB of DDR3 memory, a 320GB hard drive, an external USB optical drive, and 802.11a/g/n. Gaming chores are handled by Nvidia's GeForce GT 130M graphics.
On the next rung sits the P510-UP95K, which ups the ante with an Intel Core 2 Duo T9550 (2.66GHz, 6MB, 1066MHz frontside bus), twice the amount of RAM at 4GB, and a beefier 500GB hard drive.
The LG XNote P510-UP98K is the top model in the series, boasting an Intel Core 2 Duo T9800 (2.98GHz, 6MB, 1066MHz frontside bus), and comes equipped with both a 64GB SSD and 500GB hard drive.
Each model comes with Windows Vista Home Premium and a textured chassis. No word yet on pricing or availability.
iBuyPower does their very best to sing the hymn of the bargain computer shopper, and this time they’ve managed to come out in tune. Their most recent verses are the Dragon Based Gamer HAF 91B and the Gamer Fire.
The HAF 91B will feature Phenom II X4 CPU 920 processor, 4GB DDR2, 500GB HDD, an ATI 512MB Radeon HD 3850, and will run you about $999. The Fire runs along the same lines, featuring a Phenom II X4 940 CPU, 750GB HDD, and the rest of the hardware essentially the same for $1,439.
If you’re looking for a new gaming rig on the cheap, don’t hesitate to check these two out. On paper, they look to be mighty steady choices.
Sony Music Entertainment became the first of the four largest recording companies to renew their music licensing deal with YouTube.
The renewal has ensured that Sony artists will remain on the video-sharing site exclusively. Deals such as this allow YouTube users to not only view the artist’s music videos, but to also use the label’s songs in their clips.
It’s been reported that Universal Music Group is close to breaking a deal with YouTube, and if they signed it would leave only EMI and Warner Music Group. Though, talk between EMI and YouTube ran into some trouble last month, and since then their content has been removed from the site.
It looks like everyone’s favorite online DVD rental service has seen 6 percent growth in just one month, and they’re now boasting over 10 million subscribers.
While many of these subscribers remain the average, web-queue using type, a significant portion of the newcomers are thanks to Xbox Live. To date, over one million people have downloaded the Xbox Live client, allowing the online streaming service to take huge prescient, and bringing in a mighty profit.
This number is expected to grow from here to 10.1-10.3 million subscribers by the end of Q1 of this year, and all the way up to 10.6-11.3 million by the end of this fiscal year.
