The operator of one of the largest in China services Twitter, as it is developing an English version of its platform for microblogging.

The new English version of the popular microblogging Sina is still in development, and the company has no date when it will start, Sina spokesman, Liu Qi. “The service is to our customers abroad. Not that is designed for a specific market,” he said.

Sina Chinese microblogging service has now reached 140 million registered users. But about 10 percent of users are from foreign countries, Liu added.

Launching an English version of the Sina microblogging service, will allow the company to test the waters, both in the English speaking community in China and in certain overseas markets, said Mark Natkin, managing director of Beijing Marbridge Consulting.

“Sina and all major Chinese Internet companies are all interested to see if it can expand beyond the Chinese market,” he said. “China is a big market, a huge market. But it is only part of the global market.”

Currently, the country has 457 million web users, according to the China Internet Network Information Center.

Sina microblogging that was launched in August 2009, could soon rival the size of the Twitter service in the U.S.. Later this year, Sina microblogging service aims to break the mark of 200 million euros, equivalent to the current number of registered users on Twitter.

But while Twitter has users worldwide, the service has been blocked in China since 2009, after ethnic riots that occurred in the Xinjiang region of the country. The Chinese authorities have blocked other social media and networking sites like Facebook and YouTube, in an effort to curb the politically sensitive information.

Since Twitter has been blocked in China, microblogging has grown to become one of the most popular Internet services in the country. Sina rival Tencent operates a microblog Chinese with 160 million registered users, only a year after its launch. The microblogging, however, are heavily regulated by the Chinese government censors, which blocks searches on certain terms that are related to political protests.

Sina has already launched an English language interface of microblogging through an application for the iPhone, which also meant for users abroad. During a speech in April, Sina CEO Charles Chao said many foreign users of the product from Hong Kong, Taiwan and North America.

But Chao said the company first focused on building its service in China. Any expansion abroad is done through local partners, he added.

With more than 47 million domain names under management, GoDaddy is a great DNS infrastructure has been updated to support the security standard known as Internet pop DNSSEC DNS Security Extensions.

one year GoDaddy engineering effort to prepare DNSSEC is significant, as the most popular Internet domain -. com – support DNSSEC end of March, according to operator com Verisign.

BACKGROUND: Half of federal web sites does not prove DNS security

DNSSEC is an emerging Internet standard that allows Web sites to verify their domain names and corresponding IP addresses using digital signatures and public key encryption. DNSSEC prevents Kaminsky style attacks, where the traffic is redirected to a legitimate Web site of a false without the web site operator or end user to know.

Internet Root Servers in the top of the DNS hierarchy added support DNSSEC last July. Over 25 domains – including governments, .. org, education and network -.. DNSSEC has allowed since.

The next major milestone for DNSSEC is for the safety standard to be enabled in the domain. Com, which has more than 80 million names registered a total of 205 million names registered in all top level domains (TLD), according to statistics from February 2011.

World’s leading domain name registration, GoDaddy support DNSSEC six top-level domains:. Org, net, us, biz, eu and …… GoDaddy will support DNSSEC. Com next week, when Verisign offers this additional security.

“Because GoDaddy handles a third of all DNS requests in the world, we must be careful with everything we do,” says Rich Merdinger, senior director of services for domain registration with GoDaddy. “We put in a lot of due diligence and a long run time” for DNSSEC.

GoDaddy offers DNSSEC as part of its new offering DNS Premium, which also includes hosting DNS and Secondary DNS. DNS Premium costs $ 2.99 per month for five domain names.

GoDaddy engineers wrote their own software to support DNSSEC grown based on the company Web Manager Domain Manager systems and platforms.

“We offer a one-click solution where we manage the key management and key renewal behind the scenes for the user,” says Merdinger.

GoDaddy ran a seven-month trial of DNSSEC. Org names June 2010 until February 2011 when the company announced its premium commercial DNS service.

“We started small for the power user to hold its own DNS,” says Merdinger. “It was a very small group, and was, literally, the early adopters who have the means to generate their own keys to their domains. We had less than 300 people involved in the early adopter phase. They were IT professionals who were trying learn about DNSSEC in the practical world, real. ”

Today, GoDaddy has around 400 customers of its premium service DNS are actually signing their domains using DNSSEC. “It was a very gradual adoption has not arrived in frantic as” Merdinger says.

However, GoDaddy is anticipating that this will increase when the area com. Signature.

“Definitely there is some pent up demand for DNSSEC in. Com,” says Merdinger. “We have almost as many people pre-configured for DNSSEC. Com actively as we have set. Net at this time.”

GoDaddy technical obstacles facing the deployment of DNSSEC is that top-level domains have deployed DNSSEC otherwise, with the signing of several algorithms and key lengths.

“You really have to deploy DNSSEC on a per TLD, making sure they understand the nuances of each application,” says Merdinger. “While DNSSEC is a norm, is not enough wiggle room in the standard you must ensure that adapt to each TLD.”

Two researchers may have found a way to greatly reduce traffic bottlenecks that could take place in ad hoc networks. Seeking work may be essential for the future development of sensor networks, they say.

Keren Censor-Hillel, a postdoctoral research student at the Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory, and Hadas Shachnai to associate professor of computer science at the Technion Israel Institute of Technology, presented their work last week at the 2011 Symposium on Discrete Algorithms, held by the Association of Computing Machinery and the Society for Industrial and Applied Mathematics.

Ad hoc networks are styled predicted to be used widely in the decades to come. As the cost and power requirements of processors continue to decline, they can be used in large numbers in low-power sensors that could monitor anything from potential volcano activity to highway traffic.

By their very nature, ad hoc networks are not managed by any one controlling device, tested as a router. Instead each, end-node acts as a router, forwarding any data generated or it gets to its nearest neighbor rates, and the data will eventually make its way back to a collection point for the network.

Typical designs for ad hoc networks have each end-node randomly select another node to pass its data onto. This approach is designed to Ensure that traffic is distributed evenly across all the nodes. If one node goes down, another can take its place. The problem with this approach, however, is that bottlenecks could be created when only a few end-nodes are tasked to convey all the traffic.

The algorithm developed Shachnai Censor-Hillel and spreads out the traffic in a way that Preventer Search bottlenecks. In their approach, a node selects another node at random every other time data needs to be conveyed. In the alternate rounds, the node sends traffic not at random but to a node it has not communicated with recently.

Alessandro Panconesi, a professor of computer science at Sapienza University of Rome and an expert on network analysis, Concluded that the algorithm is “an interesting contribution.”

“Essentially, a node in this network can wake up and start operating by using this algorithm, and if every node in the network does the same, then you give Essentially communication capability to the entire network,” said Panconesi in a statement.

He cautioned, however, that this algorithm in its current form is still too elaborate for simple computational devices. Because devices on ad hoc networks tend to have limited computational power and battery life, they require very simple networking protocols. “The algorithm is very expensive in terms of the information that it needs to exchange,” he said, adding that a simplification of this algorithm would be feasible.

Ministry of Communication and Mass Media of Russia advocates the area to make way to build e-government. Minister of Communication and Mass Media of Russia Igor Schegolev has called representatives of the early establishment of e-government systems by providing solutions and services of the Russian Telecommunications Corporation Rostelecom. Igor Schegolev addressed the issue at the meeting of Regional Council’s Information Technologies Russia in Moscow recently.

Temporarily, in the web services unified national, not regional service. According to Igor Schegolev ideas, the creation of a regional branch of e-government system in Russia and to connect with the holder of Federal system would be simpler and more savings if the region to abandon the idea of creating its own platform IT manager accept the solution of e-government is unified Rostelecom.

Ministers warned colleagues in the region: “It absolutely can hire your own team of security information (e-government), you can create the business of construction to the transmission layer can be constructed a data processing center of its own, but I assure you that transmit traffic only 5% – 7% according to their ideas Igor Schegolev, however, must focus on the areas of services transferred to the form of electronic, while interest in the network infrastructure is configured as a specialized agency Rostelecom .

Mozilla Firefox browser company, last year 104 million dollars (76 million euros) taken in. This represents an increase of 34 percent over the 2008 revenues of $ 78 million. The main sources of revenue for the company’s final annual report of 2009, according to search partnerships. Most sales are expected to refer the Mozilla market leader Google, even if the balance of the membership fees include multiple search. Instead, Mozilla summarizes Google’s revenue with other partners such as Yahoo, Yandex, Amazon and eBay together.

The 2008 contract renewed with Google will last until the end of 2011. On the browser’s built-in search box, Google directs traffic to Mozilla. In return, the manufacturer of the browser with a revenue share of the search results next to the ads. “We believe that search providers forward to hear Mozilla solid revenue will remain for the foreseeable future,” reads AFAQ Annual Report 2009. The cost increase between 2008 and 2009 by 26 percent from 49 million to $ 61 million U.S. dollars

Most of the expenses spent on the personal computer and equipment. The number of employees in late 2009, Mozilla is in the world with Mozilla 250th currently has about 300 employees. 500 people working on the translation of the browser, and some 1,000 volunteers contribute code to Firefox. 400,000 users have accounts in Bugzilla to report bugs. The number of beta testers with 800,000 Mozilla. In addition alleged use over 400 million Firefox. 140 million users daily access to the Internet browser.
