Samsung B7722i Dual SIM Mobile Phone with Touchscreen

Samsung launches the B7722i a dual SIM mobile phone on the market. The mobile phone is operated by touch screen for taking pictures, there is a 5-megapixel camera.The B7722i Samsung has two SIM card slots. One slot supports only the two GSM networks with 900 and 1800 MHz. The other slot will work in all four GSM networks and supports UMTS including HSDPA technology with a bandwidth of up to 3.6 Mbit / s. Probably both SIM card slots also support GPRS and EDGE, this information did not, however, Samsung.

The parallel use of two SIM cards used one hand to separate the personal from the professional use of mobile phone use. As a further application for a SIM card abroad can the local network operator can be used. This can be circumvented high roaming charges and the user is on the regular phone number remains achievable.

The B7722i is operated by a 3.2-inch TFT touch screen. The display with a resolution of 240 x 400 pixels up to 262,144 colors. All entries must be made across the screen. For photo and video recordings, there is a 5 megapixel camera with autofocus and photo light. Here are the camera features Smile Shot, Panorama, Macro, and continuous shooting are available. The phone supports Bluetooth 2.1 and Wi-Fi 802.11b / g.

The mobile phone is equipped with a Google Maps client, an FM radio and a music player. The internal memory is about 47 MB. Slot can be utilized by micro-SD cards with up to 16 GB. The operation of the mobile phone is on, developed by Samsung TouchWiz interface. With a special widget to the user can easily switch between the two SIM cards.

Battery lasts for up to 12 hours talk time

The mobile phone measures at a weight of 112 grams 114 x 56 x 14.3 mm. The lithium-ion battery with 1,200 mAh to the UMTS business to achieve a talk time of 6 hours. In GSM mode, the extended talk time on one battery charge to 12 hours. In standby mode must be charged the battery after about 13 days.

Linux Kernel 2.6.38 Brings Performance Boost

Linus Torvalds has just under two and a half months after publication of the previous version 2.6.38 of the Linux kernel released . It stands now as a tar archive or as a single patch to download ready. In total she brings more than 9,000 changes.

Among the many additions to drivers and support for infrastructure is one of AMD's Fusion APUs . The Accelerated Processing Units integrate multiple processor cores on one die and a DirectX 11-capable graphics chip. The Wi-Fi drivers for chips from Atheros, Broadcom, Intel, Ralink and Realtek were optimized.

The most important innovation is the "wonder patch" advertised function Automatic Grouping Process: It shares the CPU processing power on so that slow is not particularly power-hungry processes them. These changes in the process scheduler to significantly reduce the latency and response such as desktop environments much more quickly.

Another important change and Torvalds' personal favorite is the improved scalability of the Virtual File System (VFS). The use of RCU (Read Copy Update) are file system operations that use a lot of file paths, massively accelerated. Of which will benefit nearly every program on a multi-core processor system even if it uses only a single thread.

The file system Btrfs untertützt now an alternative to the zlib compression algorithm, LZO . Moreover, it can now write protected create snapshots.

Transparent Huge Pages make it possible, 4 KByte memory pages to use in transparent applications over. This increases the performance of memory management, while the memory requirements decrease. A list of all changes in kernel 2.6.38 is found in the 6.3 MByte Changelog . For more information, visit kernelnewbies.org .

The new Linux kernel 2.6.38 will include the distributions in Fedora 15 and Ubuntu 11:04 come to use. Both are to appear in April.

iPhone Alarm Clock : Again Problems with the iPhone by time Change

Once again, the clocks are changed in many countries worldwide. And again zickt the alarm rings and the iPhone Alarm Clock just not when it should. The problem occurred even in the changeover to the winter time in November 2010. Apple has supposedly fixed the problem with a software update.

The alarm problem of iPhoneis returned. And it's worse than before. In the U.S., the watches were introduced in the last night of Saturday to Sunday. The following Monday, many users complained that they were late to work because they were awakened by the iPhone too late. Instead of ringing an hour earlier, had to reset the alarm clock of its iPhone for an hour and ran two hours late. The Clock of the iPhone displays the time on the other hand correctly.

The iPhone alarm clock had been to switch to winter time causes problems. Even then, set the time the Apple handset to on, the alarm took over the new time but not regularly, and then rang an hour later than never. Apple to fix the bug later with a software update.

In Germany, the time on Sunday, 27 March at 2:00 clock in the morning presented to 3:00 clock. Who can awaken from his iPhone should, therefore, on Monday, 28 March make a second better comparison to the bed to get up on time.

Tweets 1 Billion in One Week,Twitter Celebrating Anniversary

Twitter is celebrating its fifth anniversary. For the anniversary, Twitter has even published some figures on his blog that show how the micro-blogging service has grown in recent years.

In March 2006, it all started, a small team consisting of the founder Isaac "Biz Stone, Evan Williams and Jack Dorsey, is working on a prototype of Twitter. First, the service was "twttr referred. Later this was renamed to Twitter. So Twitter has developed:

  • It took three years, two months and one day, sent to a billion tweets were. Now this amount is reached within a week!
  • A year ago, were sent average of 50 million tweets per day. In February 2011 there were 140 million per day. The strongest days: 11 March 2011. Since 177 million was Twittering time.
  • On 25 Michael Jackson died in June 2009. On this day 456 tweets per second were withdrawn. Four seconds after the year 6939 were measured tweets per second.
  • Every day gets Twitter 460 000 new users. Proportion of mobile users increased by 182 percent last year.
  • The team was larger. In January there were eight permanent staff, now in March it will be 400th

Twitter can therefore rightly be proud of these numbers. Nevertheless, enjoy, especially the daily new account numbers with caution. Twitter says that is not as attend many of these really active.

Exactly that is of course a big problem, many of the new users do not participate in listen only to the Twitter stream. Nevertheless, Twitter is larger and still tries to be profitable.

E-books: Revolution with Obstacles

The E-book is intended to allow authors to bypass publishers. But there is a startup problem, the reader is attached to the paper. Amanda Hocking was once a geriatric nurse. Now she's gravedigger an entire industry. The 26-year-old American woman writes vampire novels. Their attempts to inspire, literary agents for the works failed. Ado Hocking then published their books in digital form on Amazon - no publisher, no book stores.

Anyone with an e-book reader of the Internet department store, order the books online. More than a dozen different titles Hocking has published through this channel, earned several million dollars in this way.

Hocking is only one example among many - and scares the literary world. Were e-books so far primarily an American phenomenon counted, the Association of German Book Trade in this year a "breakthrough" for digital literature here with the country. "Value chain within the industry is the change," said Alexander Skipis, chief executive of the Association of Süddeutsche Zeitung . In other words, no stone is left unturned.

Digital books are still a niche business. The e-book sales is a share of only 0.5 percent or a two-hundredth of the total revenue from subscribers in Germany.

Just 21.2 million euros have been implemented last year in Germany with e-books, except for school and books. Comparative figures are missing. The Booksellers Association has the numbers now, first levied for the segment and made public on Monday.

Every tenth point is digital

In the United States there is such market studies for some time. According to Association of American Publishers there the business grew with electronic literature in the past year by 164 percent to 441 million dollars. Almost every tenth book will be delivered in the States according to the figures from the Publishers' Association already in digital form.

For Germany, the Stock Exchange Association now expects a similar development. "The market for e-books will take shape this year, so that we can generate significant revenues in some years," said Exchange Club chief Skipis. The publishers estimate that e-books in four years make up 16 percent of all book sales. The book trade is more pessimistic: he believes that, in 2015 only nine percent of the proceeds from the sale of digital product.

The discrepancy can be explained by authors such as Hocking. Those who buy his e-book on an electronic platform, does not need a bookseller. More than half of the surveyed store owner anticipates that by 2015, with sales declines.

Nine percent were raised even to a softening of the market by a quarter of today's sales one - or more. "The book trade, it must succeed, the customers who come to him today in the shop, and virtually retain them," says Skipis.

exist to counter the Great in the network, is for the bookseller from next door but no easy task. The computer manufacturer Apple, the Web retailer Amazon and the search engine giant Google: The U.S. companies operate e-book stores on the net and have the experience from the United States.

The three have been taught to fear other industries, such as the music industry whose business model has collapsed over the past decade. In the U.S. now sells no one - even offline - more music than Amazon. Do not worry is: "Everything that serves the book is good at first," declares the Exchange Club general manager.

Publishers are unnecessary

In view of the boom there is a whole different problem. The customer. The German loves the printed book. 82 percent prefer buying books on paper, up even to a survey of 2009. Only two percent like it electronically.

Above all, easy to use tablet computers like the Apple iPad, such as the simple purchase of a book store in the iBook will be passing the test customer. Skipis also expects price cuts for e-books when the investments have paid the publishers for now.

The best book by Internet-best-selling author Hocking costs less than a dollar. A millionaire she has made the online sales of their books because of the sheer masses anyway.

As a gravedigger looks Skipis still not the business model Hocking. "Of course, authors can make their books online, but that it is not done," he says. "Editing, production, market positioning - this will always require a publishing house."

Microsoft has Released its iPod Rival a Zune

Microsoft is competing with Apple's iPod to appear. According to a report by Bloomberg wants the software giant production of its media player "Zune" and set the new models to market more no more. The reason is an insufficient demand, Bloomberg reported, citing a consecrated person.

The same software will continue to be used, among other smartphones with Microsoft's new operating system Windows Mobile Phone 7 It is used there to sync content between mobile device and PC, and also to update the operating system. Also, the Zune download store for movies and music will continue to exist.

Microsoft had first Zune models introduced about five years ago that in order to compete with Apple's iPod. Compared to the Apple device Zune possessed of some advantages such as an FM radio and a larger display. After a few more versions followed most recently in 2009, the Zune HD direct competition with the iPod as a successful model touch. The units are only in the U.S. for some time now available in Canada and an international market failure.

The Zune, which was initially described in the media as the "iPod killer" could meet the high expectations, however. In the U.S., the iPod came last year with a market share of 77 percent, making it the undisputed market leader. For the Zune launch in 2006, Apple with its iPod market share of 75.6 percent.

Microsoft is reporting in a statement neither confirms nor denies. The software giant said only in North America continue to support the Zune. In addition, we look forward to the fact that the service on the Xbox 360 and on Windows Mobile 7 smartphone adopted a good thing going, they say.

Internet Explorer 9 is Available for Download

Microsoft today announced the InternetExplorer 9 published and is opening a new round in the battle for dominance in the browser market. Lost market share to be won back with the new version. We have used the software extensively examined.

The developers in Redmond have the Internet Explorerdonated a number of new features, but for many users, the new framework should be at least as interesting. It ensures that web pages rendered more quickly, while important standards like HTML5 support. The lack of performance and ignoring standards paved the way for the descent of the Internet Explorer in recent years. Relatively new products such as Firefox and Chrome could benefit from it.

Support for modern standards
Even before Microsoft features and user interface design has focused on were new, so-called Platform Previews published. In it, the developers focused entirely on the rendering engine, the display of the website is responsible for. It now supports all major standards, the Web needs to be modern in.

This is especially the upcoming version 5 of the HTML specification. HTML5 provides both in graphics (canvas, SVG) and in the field of multimedia (video and inline inline audio) new possibilities. It adds new interfaces that developers can use to easily implement various functions. The Geolocation API (Application Programming Interface) is a popular example. Furthermore, it is possible to determine the whereabouts of a user, if this is in agreement.

Another important standard supported, in the Microsoft Internet Explorer 9, CSS3 (Cascading Style Sheets) is. The style sheet language allows Web sites to create visually. CSS3 brings with it some new features such as easy ways to implement multi-column layouts as well as rounded corners of the frame.

On the website Beautyoftheweb.com Microsoft demonstrates what modern standards on web pages can be realized thanks to the support. Internet Explorer 9 is not the only browser that is capable of in modern web technologies to benefit from. Chrome and Firefox 4.0 are two popular competing products that use a similar standard-compatibility feature. The differences between products lie in the details.

The new user interface
Microsoft has designed the user interface of its browser from scratch. Already at the first start to notice that the Internet Explorer 9 is much clearer. Only the most important functions that are needed each day while navigating the Web, are accessible with one click. Everything else was to save space in the "Tools" menu located, hidden behind the small gear on the right of the window. The favorites are hidden - they are represented by an icon in a star shape.

The idea behind the design of the user interface is easy to explain. They want to give the site as much space as the browser is Microsoft's view to the window in the online world. For this reason, they located directly next to the tabs at the address bar. The eye-catching are the arrows back and forth jumping on the same level. As part of the public beta testing of this design was criticized by some users, after which Microsoft has made it possible to place the tabs below the address bar. Especially when working with many open tabs you will appreciate this. The menus can be hidden if desired map.

Otherwise, the user interface designers are more adapted to the design requirements of Windows 7. The entire window, apart from the site is transparent. Only the optional expandable menus let it be nothing.

Pinning sites
A new feature in Internet Explorer 9, which came already in the testing phase for an award, is the possibility of sites on the Windows task bar to attach 7th This must be only the favicon of a website that appears in the browser before the URL, drawn on the taskbar. Then the site can be accessed in Windows 7 directly from the Taskbar.

This new interaction possibilities on the basis of jump lists that Microsoft introduced with the latest edition of its operating system. Right-click on the pinned site opens a menu (the jump list), some of the functions of the website can be executed directly, unless the website owner has provided such support this functionality. On the basis of WinFuture.de can demonstrate this well.

Once you have attached WinFuture.de to the taskbar of Windows 7, will open when you right click on our logo, a jump list can go directly to the one of our central points of contact: news, downloads, videos, forum and if you are a registered member , MyWinFuture. In addition, the headers are displayed the three most popular news, so you never miss important news.

Who uses the opportunity to comment on the news and videos on WinFuture.de is informed of the pinned site also answers to his comments. Once this occurs, the icon flashes on and thus makes attention to new answers. When watching videos on our player WinFuture.de can control via the Preview menu that appears when you place the mouse pointer briefly on the Tech Support logo in the taskbar.

Download Manager
For years, want the users of the Internet Explorer download manager that allows to handle multiple downloads in parallel, in a window clearly display. Microsoft has recognized the desire and implemented in Internet Explorer 9 is a download manager with basic features. For the first time can be active pause and resume downloads at a later date.

The download manager displays a sequential list of files that you downloaded from the Internet. These can also search so that you keep regardless of where the big picture. Useful functions such as copying the download link, complete the download manager. Should be sufficient for most users the functionality to do without third-party software can.

More with Tabs
While the Internet Explorer 8 has already supported the so-called tabbed browsing, but you have to even look at competing products, it soon became clear that there is potential for improvement. That was recognized by Microsoft and also improves work with Tabs in Internet Explorer ninth

This starts already open a new tab in the. There is now a list of sites most often shown open. A small bar for each entry is information about how active you Each web site is up. About the "Suggested Sites" can be based on the personal conduct, a surf of websites can be set to propose that may be of interest.

The tabs themselves have learned. So you can now pull it out of the tab bar, and thus constitute a separate window. For Windows 7, this can also be combined with the popular Aero-snap function, scaled to the window half the width of the screen as soon as she moves to the left or right margin. In this way, let's face, for example, two Web sites. A color-coding the tabs will show which sites are related.

Improved Add-on Manager
Internet Explorer can be by using add-ons extend the functionality. In particular, the toolbars offered by many companies should be negative for some users in mind. In Internet Explorer 9, Microsoft has equipped the Add-on Manager, and reviewed with a useful function.

Often provide toolbars and other add-ons for the browser to start noticeably slower. Microsoft is now in the dialog box there to disable add-ons, a graphical analysis of the start time. For each add-on is specified by how many seconds it delayed the launch of Internet Explorer ninth This allows service brakes to see at a glance and a click are disabled later.

Searching is simple, notifications do not interfere with Chrome shows the way, Microsoft makes it to the Internet Explorer 9 to integrate instead a separate field for requests to a search engine, a combined address and search box is offered. If you give it a full address can be done as usual on the site - it is a keyword or incomplete address, the default search engine is ready. Upon request to the respective input and searches are presented, but this function must be explicitly enabled.

A further innovation on the Microsoft attaches great significance, the newly designed notifications. These no longer appear in the form of a dialog box that interrupts work, but as a discreet bar, which moves at the bottom in the visible range. When notifications are, for example, downloads, the question is whether a password is stored, or the reference to a missing plug-in.

Hardware acceleration
The newest trend in the browser developers, the hardware accelerated display of Web sites. Processor to the rendering of the burden instead, the graphics card is used, which when surfing the Internet typically bored. Microsoft explains clearly that the sites on the Internet Explorer 9 how applications behave on the PC.

From the additional computing power of the GPU to benefit particularly in high-definition video, as it offers such as YouTube. Since the browser is now used as a gaming platform and it runs games in the browser, there are more opportunities here, because the developers can make use of such products to the greater power reserves. The Windows APIs Direct2D and direct write approaches were used. If the canvas element in the HTML5 standard used, the calculation is accelerated by graphic elements.

Tracking Cases & ActiveX Filter
The Tracking Protection, called on the German Internet Explorer 9 and tracking protection is to increase the safety of operators. According to Microsoft, can thus prevent the unwanted forms of tracking. The user can specify exactly what personal information can save a site.

An open platform Microsoft distributed the so-called tracking protection Lists (TPL). They contain the addresses of sites that may invoke the browser unless the user explicitly clicks on a link or typing directly. If one of the addresses call when another site, thus the collection of user data is prevented.

The tracking protection is completely voluntary and therefore disabled by default. If necessary, they can be activated in the options of Internet Explorer ninth In addition to the common open platform Tracking Protection Lists can also create your own lists with specific URLs, which can then disseminate it.

Using the ActiveX filter can decide which ActiveX elements on an open site may be shown. Especially in Asia, the ActiveX technology is still used in many places, such as Web sites of banks. Basically out of the Internet Explorer ActiveX controls from 9 does not - say the user must explicitly which components can be loaded.

Benchmarks
Compared to Internet Explorer 8, the Microsoft developers with version 9 is a huge performance leap lying down, especially in the execution of JavaScript code. We have the latest browser in three benchmarks against each other and attack each case back to the latest final build. The only exception is Firefox, which we can compete in version 4.0 RC. Here, the final version will follow shortly.

The SunSpider JavaScript benchmark (version 0.9.1) was able to secure the Internet Explorer 9, the first place. As the only browser he remained under the brand of 200 milliseconds. The competing products are very similar, only Apple's Safari is out of line and 284 milliseconds with the red lantern.


The V8 JavaScript benchmark of Google, the performance gap is very different. Here comes Chrome 10 in the first place and creates competition for a large safety margin. However, this good performance meets expectations, finally, the V8 JavaScript benchmark used internally for all improvements and considered a success knife. The Internet Explorer only 9 landed in fourth place, in Safari, but behind Firefox and Opera.

The third benchmark we have chosen for peacekeepers from Futuremark, which also measures the performance of JavaScript, but it works according to the makers very practical. Here, too, Chrome 10 comes easily in the first place. Internet Explorer 9 ranked third, is however significantly behind Chrome and Opera. Only Safari and Firefox have performed worse at Peacekeepers.

However, one should not judge the speed of a browser, not only on the basis of benchmarks. Subjective factors often play a major role - one might speak of a "perceived speed". In this discipline is the browser of Microsoft not hide behind the competition. In the editorial, however, Tech Support consensus emerged that Chrome remains the Performance Reference.

Usage statistics
Already in the test phase, the Internet Explorer 9 win over some users. Microsoft hopes that the lost market share in the past can be recovered using the new version. Among the users of the Microsoft browser features already the trend to switch from what the software group contributes with an extensive advertising campaign.

In February 2011 the set of WinFuture.de 15.88 percent of visitors to the Internet Explorer browsing use, pre-release edition 9.0. Internet Explorer 9 was so even before its release to a total share of 4.17 percent under the WinFuture readers.

Conclusion & Outlook
Microsoft Internet Explorer displays the 9 that the browser is playing in the company's strategy is an important role. With the current trend toward cloud computing, the little wonder. The new version is a huge step in the right direction dar. During the development it was clear that this project will be crowned with success, because it seemed right for innocent bystanders, that first of all to the underlying platform, while focusing the optical functionality in mind was.

What plans has the Microsoft Internet Explorer is at present unknown. None has yet been no discussion of the version 10 that will follow with great probability. The development team has a lot of work to do, because the competition has many useful functions that are missing from Internet Explorer. A reasonable extension system, and synchronization between PCs are just two examples. One may be curious what the future holds.

Geforce GTX 550 Ti in The Test: The Better Radeon HD 5770?

The GeForce GTX 550 Ti comes with higher clock and memory bandwidth, the successor to the Geforce GTS 450 on. The test checks PC Games Hardware, GF116 whether the graphics card to the declared enemies Radeon HD 5770 can beat the GeForce GTX 550 and special offers which Ti.

After the partially somewhat hapless GTX/GTS-400-Familie Nvidia launched in autumn 2010, the revised 500 series, which is on three models introduced so far: The GeForce GTX 580 was the first Fermi card with 512 ALUs in full ( PCGH Test ), the GeForce GTX 570 ( PCGH Test ) inherited the GTX 480 and GeForce GTX 560 Ti ( PCGH Test displaced) as the successor to the popular GeForce GTX 460, the GTX also spread 470th Now Nvidia is building out the lineup and sends the Geforce GTX 550 Ti into the race. This is positioned above the Geforce GTS 450 ( PCGH-Test ) and the Radeon HD 5770 set against which OEM segment as Radeon HD 6770 is sold. The Geforce GTX 550 Nvidia Ti designated as "Sniper Reloaded" (based on the "Sniper" GTS 450), the official price ("MSRP"), the manufacturer with 120 Euro plus VAT, so about 140 €. This coincides with the launch prices of the GTX 550 Ti

Geforce GTX 550 in the test Ti: Specifications of the GF116
As with all other cards of the 500-series Nvidia talks about revised transistors in the GPU, the graphics chip is called, therefore, instead of GF116 GF106. The technical data of the GPU are identical to the Geforce GTS 450: The 1.17 million transistors are divided among other things, a GPC with four multi-shader processors. Thus a total of 192 ALUs and 32 TMUs are available. Were with the GTS 450 only two 64-bit memory controller active, it is the GTX 550 Ti the full number of GF116 - this is a 192-bit wide memory interface and 24 instead of 16 grid amplifiers. Interestingly, Nvidia has the GF116 missed a support for storage of different sizes, so the GeForce GTX 550 Ti with 1,024 MiByte GDDR5 equipped and not actually to be expected with the 768 MiByte.

To the GeForce GTX 550 Ti apart from a wider memory interface to the GTS to accelerate 450, Nvidia has increased the speeds on 900/1.800/2.052 instead 783/1.566/1.800 MHz. So are 15 percent more computing power and a 71 percent increase in memory bandwidth available. The remaining technical details are as follows: Support for DirectX 11, OpenGL 4.1, Open CL 1.1, PhysX, CUDA, SLI, 3D Vision (plus surround SLI), optional HQ AF, SGSSAA in all APIs and True HD audio Bitstreaming and DP performance equivalent to one twelfth of the SP performance. The reference design offers two dual-link DVI ports and a mini-HDMI port and a dual-slot cooling Axiallüfterbasis on which we exchanged this Palit card has a DVI to a VGA port. A special feature is the single 6-pin power connector: Apart from the GTX 460 in the OEM version is the Geforce GTX 550 Ti the fastest Nvidia card with this type of power supply. For AMD this is the Radeon HD 6850 and which is clearly faster and more economical, much was said.
