When you type www.lwegatech.com into your browser's address bar, you expect nothing less than to be taken to lwegatech website. Chances are you're not giving much thought to the work being done in the background by the Domain Name System, or DNS.
Today, as part of ongoing effort to make the web faster, google launched a public DNS resolver called Google Public DNS, and the public has been invited to try it out.
Most of us aren't familiar with DNS because it's often handled automatically by our Internet Service Provider (ISP), but it provides an essential function for the web. You could think of it as the switchboard of the Internet, converting easy-to-remember domain names — e.g., www.google.com — into the unique Internet Protocol (IP) numbers — e.g., 18.104.22.168 — that computers use to communicate with one another.
The average Internet user ends up performing hundreds of DNS lookups each day, and some complex pages require multiple DNS lookups before they start loading. This can slow down the browsing experience.Research has shown that speed matters to Internet users, so over the past several months google engineers have been working to make improvements to the public DNS resolver to make users' web-surfing experiences faster, safer and more reliable thus the born of Google Public DNS.
Google Public DNS is a large set of DNS servers placed around the world. Interestingly, even though the number of caching DNS servers is apparently quite high, Google only uses two addresses for them: 22.214.171.124 and 126.96.36.199. (It looks like Google turned to Level3 to get some easy to remember addresses for this purpose, rather than use addresses out of their own, less-memorable address ranges.) The routing system simply delivers packets addressed to either address to the closest Google Public DNS location. So users in different places around the world will be talking to different instances of these addresses, making for faster round-trip times, which is important for good web surfing. This mechanism is called anycast.
Google uses clusters of servers at each of the anycast locations that collectively cache information, allowing requests to be rerouted from one server in the cluster to another. This provides better caching and thus better performance than simply distributing incoming DNS queries over a set of independently operating servers. Additionally, they've developed a system that can refresh information that is about to expire (all DNS records contain a "time to live" value), rather than removing stale information and then having to do a lengthy lookup when it's requested again by a user
If you're web-savvy and comfortable with changing your network settings, check out the Google Code Blog for detailed instructions and more information on how to set up Google Public DNS on your computer or router.
In an online statement issued by google. As people begin to use Google Public DNS,there's a plan to share what learnt with the broader web community and other DNS providers, to improve the browsing experience for Internet users globally. The goal of Google Public DNS is to benefit users worldwide while also helping the tens of thousands of DNS resolvers improve their services, ultimately making the web faster for everyone.
Unfortunately, despite the anycasting, advanced caching, and extensive security features, Google Public DNS is not the ideal DNS service for your primary dns server .it's in its experimental stage so my advise is to setup alternative DNS servers on your gateway.
More good things to come in 2010 that will help you save costs in all round activities. Himax Technologies announced the introduction of iCT (Infinity Color Technology), an innovative and proprietary image processing technology which enables significant power saving for TFT-LCD TVs and monitors, regardless of CCFL (Cold Cathode Fluorescent Lamp) or LED (Light-Emitting Diode) backlights, while enhancing image quality.
This technology developed by Himax Media solutions, a Himax subsidiary, the innovative iCT is a unique and cost-effective approach in optimizing power efficiency and image quality.
Power saving is an important concept in the flat panel display industry. For example, the California Energy Commission recently approved an energy efficiency standard for televisions. When the standard is implemented in 2011, new TVs sold in California should consume at least 33 percent less electricity. Likewise in China, the worlds largest TFT-LCD TV market, a similar energy-saving concept has been advocated at various events. However, with current power-saving technologies, there is always a conflict or trade-off among power-saving, image quality, and the costs to achieving both goals. To optimize energy efficiency, panel and system makers are aggressively seeking the best solution which has promised a bright future for green technologies.
TFT-LCD backlight, either CCFLs or LEDs, typically maintains a constant brightness at all times, regardless of the displayed images. One commonly-adopted technique in saving backlight power is CABC (Content Adaptive Backlight Control) which dynamically adjusts the backlight and contents. While this pure digital approach is able to save panel power, it inevitably leads to loss in gray scales while adjusting gamma curve and thus an undesired image quality. These side effects could be mitigated by using 10-bit or higher TFT-LCD panels, as adopted by a few Japanese tier one TV brands. However, higher bit TFT-LCD panel also leads to higher costs, which prevents wide adoption.
For the first time in world cup history 3D technology will be used to film atleast 25 of the world cup games.
FIFA confirmed that they will have 3D Cameras used to capture the games. Although it has no definite plans to broadcast the matches live in 3D, Fifa said it was a possibility and would be decided in "the coming months". Initially, it said, footage will also be shown at public events in seven cities around the world. The footage will also be packaged into a film.
Sony technology will be used to film the games, although the firm has not confirmed details of the specific technology it will use.
According to the review on 3D done by BBC news " The majority of existing 3D set-ups use two-camera systems to record images tailored specifically for the left and right eye of the viewer. Special polarised glasses are then used to view the image.
However, earlier this year, the Japanese firm unveiled a single-lens camera, which it said was especially suited for sporting events.
The camera takes a single image that is split by mirrors and recorded on two sensors. 3D technology has been used to capture special events before, such as the Queen's Coronation.
However, regular and widespread use of the technology is still in its infancy. Now, analysts believe the technology is on the cusp of becoming mainstream and believe the World Cup could play an important role in take-up of the technology.
"Global sporting events... are very important drivers of new technology, particularly in the TV market", said Tom Morrod, Senior Analyst at Screen Digest. he firm predicts there may be 13.6m 3D TV sets installed in Europe by 2013.
In 2008, the BBC broadcast the world's first live sporting event in 3D, beaming back an England vs. Scotland game from the Six Nations to a cinema in London. The corporation's director of London 2012, Roger Mosey, has said there are also plans to capture some of the Olympics in 3D.
In July this year, broadcaster Sky said that it would launch "the UK's first 3D channel" by 2010. It has also hinted that it may launch a sports channel which could include Premier League Football in 3D. The World Cup begins on the 11 June 2010.
Phew!! Atlast we have got a solution to long lasting data backup. A disc that is to make us keep all the memories for even our great great kids.
A new 1,000 year DVD made of high tech, diamond-hard stone promises to preserve irreplaceable digital files for the ages.
The DVD was designed by a team of talented scientists to store digital photos, movies, music, documents, and ledgers for 1,000 years or more. By the way you can get this at less than $40 dollars.
Unlike conventional recordable DVDs and CDs, the Cranberry DiamonDisc has no adhesive layers, dye layer or reflective layer to deteriorate - thereby avoiding the "data rot" that quickly corrodes all recordable DVDs. The transparent Cranberry DiamonDisc can withstand prolonged temperatures extending up to 176 degrees Fahrenheit as well as UV rays that would destroy conventional DVD disks. The Cranberry DiamonDisc is playable on most regular DVD drives today and will last as far into the future as we can imagine
Unfortunately, each disc holds just 4.7GB of information.
Of recent as I was doing my normal surfing spree, happened to check out the CNN website…yes the NEW CNN.COM. Whoever is behind this master piece of cnn.com is really a genius who knows what it takes to have a beautiful, eye catching and user friendly website.
The header of this site is a really eye opener with very attractive reddish color, a CNN logo with earth globe in the center that makes you love to read the news and not wish to leave this spectacular view. This site gets my 100% in:-
- Website organization
- Color pick and mixture.
- Nice graphics.
- User friendly.
With the new website you can easily locate what you want to read easily and faster unlike the old website which was kind of boring, poorly organized and had to much of white. However this new one!! Is state of art for web lovers?
Well looks like CNN is not the only website redesigned, MSN.COM also got a small twist in its content organization.
