Microsoft is a platform Windows Phone 7 Series

Windows Phone 7 SeriesAt the event, Mobile World Congress 2010 company Microsoft Microsoft introduced a new software platform - Windows Phone 7 Series. I must say that renaming the Windows Mobile OS in Windows phone contributed not only sophisticated marketing. The fact that the new version of mobile OS is truly different from its predecessor. Almost from scratch rewrite of the interface, it is more informative, it appeared a large number of dynamic elements that, although a negative impact on performance. Full documentation for developers yet, but it is clear that the majority of applications designed for older operating systems will have to be rewritten. At the core software for Windows Phone 7 Series is. NET Compact Framework, is also supported by technology Silverlight (an alternative to Flash from Microsoft). Special emphasis is placed on the operating system in a number of integrated services: a set of preinstalled applications to work with blogs and social networks, Windows Phone Hubs, combining similar content from the Internet gaming service Xbox LIVE, Marketplace, etc. Each device that is running Windows Phone 7 Series, will be a separate button to switch to Microsoft's search engine Bing. Unfortunately, announcement did not signify the completion of the platform. Production of smartphones running Windows Phone 7 Series, will only begin to Christmas, and during that time the situation will change: for sure Google will release a number of versions Android, will go on sale the next generation iPhone, Samsung is actively promoting Bada OS, and even Symbian^3 is also impossible underestimate the (already has information on the first working under this OS smartphone - Nokia X10), and whether Microsoft's platform to the end of 2010 this innovative and relevant, what is now, time will tell.

U.S. cellular operators will use Skype.

At the recently concluded international conference in Barcelona Mobile World Congress the largest mobile service provider Verizon Wireless has signed a historic partnership agreement with IP-telephony provider Skype.

cellular operatorsIn accordance with this agreement, Verizon subscribers will be free to communicate via Skype. International calls will cost two cents a minute or three dollars a month. The program starts in late March and will be available for owners of 9 types smartphones.

In addition, as reported by The Washington Post, the company will develop mobile offer Skype for smartphone 3G. Downloading an application that will allow Skype users unlimited calls to other Skype users in the network of U.S. operator, and also to make international calls at rates Skype. Calls to any non-Skype number will be calculated at rates Verizon. Annex Skype Mobile will include instant messaging, social networking tools, and then it will be possible to conduct video conferences.

Experts have called the agreement a breakthrough in the outlook of telecom operators. Prior to that, in relations Skype with mobile operators and wireline reigned real hostility. Many operators have blocked the application Skype on mobile phones. Until recently it was only available on the iPhone and only mode Wi-Fi Hot Spots. Last fall there was some easing of tensions on the part of AT&T, which said that the program will allow Skype to work in the phones of its customers, but so far nothing concrete has not been done.

Verizon became the first U.S. operator that will actively promote the services of Skype. "This is a breakthrough ... We feel this change in thinking operators. The attitude of some operators is changing fast", - said in an interview with Reuters, CEO of Skype Deosh Silverman.

In Verizon hopes that by offering services to Skype, they can attract more customers. "We go mad, the fact that 200 million Americans are not our customers. We think that providing a rich application, we will attract a whole group of new users", - commented to Reuters news director of marketing for Verizon, John Stratton. In his view, the new customers the company will generate more income than they lose on international calls.

Virus-related moves to the hardware level.

Kaspersky Lab said on patenting in the U.S. hardware anti-virus system to effectively deal with rootkits.

fighting virusesAs part of the new technology are encouraged to use hardware anti-virus - a device neutralizing the most common type of threats - malicious programs which reside on a hard drive or infect existing files on it.

The patented anti-virus checks the data to be stored on the harddisk, identifies malware and blocks their entry.

The device is placed between the storage device (hard or SSD-drive) and computing unit (CPU and memory), connecting to the system bus or integrated in the hard disk controller. When using hardware anti-virus blocks or allows writing data to disk, producing reports of threats and their actions to the user (the dialogue with the user is possible if the PC hardware tools for managing anti-virus). The device can operate separately or in conjunction with antivirus software.

Due to the hardware rather than software implementation, the new technology regardless of the configuration of the operating system and is effective for combating malicious programs that increase their privileges in the system, for example, such a dangerous threat as rootkits. Rootkits intercept operating system functions, which enables them to actively oppose their detection and removal by antivirus software, working in the same environment. Thus, rootkits are able to block the launch of anti-virus application, monitor its actions and restore deleted them malicious processes, change settings remove the registry, etc. In the case of hardware solutions are not working in an environment contaminated with the OS, all these methods are unsuccessful, and the rootkit will be quickly neutralized.

In the patented device uses its own updated anti-virus databases that are protected when upgrading from malicious code and erroneous entries. Proposed anti-virus has its own processor and memory, that is not consuming resources of the computer that is connected. If necessary, it can connect a separate power supply.

Facebook generates more traffic than Google.

Research company Compete published its latest analysis report generator of traffic.

Facebook GoogleHis results showed a new sensation - a social network Facebook bypassed internet giant Google and has become a major source of traffic on major Internet portals, such as Yahoo and MSN.

Commenting on the news, experts agree that in the near future, social media can not replace search engines as a major source of traffic to sites.

As one of the authors of the report, Dave Jovan, "people all spend less time looking through the Internet alone, and more - visiting different resources based on the recommendations of their friends or their preferences. This is one of the big trends that we saw four or five months ago.

Data Centers cool wind.

In the north-east of England, near the town of Billingham, commissioned data center with a unique cooling system that uses an icy wind from the North Sea. Climatic conditions are such that the wind was blowing steadily and constantly, and almost always in one direction. For the ventilation system is the ideal environment. Data Center Wynyard built by the contractor for EDS, HP.

Data CentersAir flows from the air first passes through filters (I wonder how they filter the salt air?), And then eight 2.2-meter fan, they come directly to the server rack. Thus, in the working room data center maintains a constant temperature of 24°C. When the wind gets too cold in the ventilation system of its slightly warmed by heat exchangers which remove heat from the servers.

In windy data center, just in case, provided the usual fans, which are activated in the absence of wind. That is not one hundred percent "green" project: for example, Google and Microsoft has data centers in general, without fans.

Energy efficiency Wynyard is 1,2 PUE (Power Usage Effectiveness), that is, for every 1.2 watts of power equipment consumes 1 watt of cooling. This is the most energy-efficient among all data centers HP. In conventional data centers figure is 2 PUE, and in the most energy-efficient buildings last time - not less than 1,5 PUE.

Announcement of environmental data center Wynyard held a year ago, and now its construction has been completed. The building has a working area of 8100 m2.

Typos for $500 million per year.

It is very simple: the so-called tayposkvottery register domains with "typos" in order to collect random traffic, and deliver the targeted ads, usually Google AdWords. The Conference Financial Cryptography and Data Security experts from Harvard announced its study (PDF), which attempted to assess the volume of the market. The authors also make the assumption that Google is providing technical assistance More Search and shares with them a profit.

register domainsAccording to their estimates, the network contains at least 938 000 domain names that are incorrect spellings 3264 the largest sites zone. Com (take into account, at least five-letter). At every popular site has, on average, 281 domain misspellings. "Erroneous" is about 1,16% of the Internet zone. Com.

Few of the research methodology. Typos were generated by model-Dahmer Lowenstein, ie replacing each letter, no letters, an extra letter or letters change places is that the new word is from the original at a distance of 1 step. To study generated a list of domains in two steps from the originals. Plus were added to typical network typographical errors (for example, the letters www in the beginning of the name of each site, etc.). For 3264 the largest site received 1 910 738 candidates. Then a random sample was drawn from 2,195 sites, which the researchers examined manually to determine the percentage of certainty. The audit score of tayposkvotterskih domain was reduced to 937 918.

The study was launched crawler, which cost 284 914 domains from the list, as alleged tayposkvotterskie. It was found that 80% of available sites available contextual advertising, and the remaining 20% is redirect.

A large percentage of the lock due to the fact that on some servers hosted tens of thousands of tayposkvotterskih domains, so that the crawler access was blocked by the regular protection from DDoS-attacks. The vast majority of them then open normally with other IP-addresses. As for the "unclassified" domains, it is, basically, sites using Javascript, which crawler can not normally handle.

What is contextual advertising is placed on the domains tayposkvotterov? At 36% of contextual advertising is the original site with the correct spelling. The bulk of the rest - a reference to its competitors.

Were also identified in 1250 identifiers affiliate program Google, who place advertisements on these domains. Identifiers can be seen in the URL after the parameter "client =". So, it turned out that some of these identifiers are more frequent than usual.

Five major Google partners cover 63% of the market, and top-10 cover 76% of the market.

Among the most popular affiliate programs are Commission Junction (905 domains of the sample), LinkShare (652) and Performics (Google Affliate Network, 290).

With regard to redirect, it identified 75 of legitimate Web sites that collect traffic from tayposkvotterskih domains. For example, service hosting image gets traffic from 128 domains, which mistakenly write the name competitors. Or the famous casino collects traffic from domains where name is written wrongly competitor Sportsbook (, and another 326 options).
