Wall Street Journal published an article that, with the rise of applications, Web is going to decline, and the impact produced by its decline is far more profound than any other current technology; the open Web lost to app store.

Think about your cell phone, there are app icons right over the screen one by one instead of the webs; those mode of operation of applications is completely different with the Web’s.

Large amounts of data shows that, nowadays, people likes to use applications just like surf the Internet in the past. People loves a variety of applications which have taken over people’s digital life. According to mobile analytics company Flurry data, people spend 80% of the time on the application, but the time on the Web, only 14%.

This data change seems insignificant. In the past, people have to print out the navigation route from the MapQuest site, and those navigation is often wrong and confusing. Today, people can get real-time traffic information through the phone’s navigation application Waze. For those who still clearly remember the old way of obtaining navigation, it is nothing less than magical.

No matter from what point of view, the application seems to be very beneficial to users – compared to Web, they run faster and more easy to use. But behind this convenience there is a major problem: the openness that allows the Internet companies to develop into one of the strongest company in the 21st century is terminated.

In fact, the application store limited to a specific operating system and device is a walled garden, in which Apple, Google, Microsoft and Amazon are the rules makers of the game. This means that Apple can block Bitcoin— revolutionary Internet progress in the eyes of the technical staff, means that Apple can off-shelf any application does not comply with its provisions, taste at any time.

(1) The computational speed. Computational speed is an important measure of computer performance. Commonly computational speed refer to the average speed of operation, also the number of instructions that can be executed per second, usually describe with mips, Million Instruction Per Second. The same computer, the time required to perform different operations may be different, and thus the computing speed is often described with different methods. The common method are use CPU clock speed, the number of instructions executed per second average (ips) and so on. Microcomputers generally use clock speed to describe computing speed, for example, Pentium / 133’s clock speed is 133 MHz, PentiumⅢ / 800’s clock speed is 800 MHz, Pentium 4 1.5G clock speed is 1.5 GHz. In general, the higher the clock speed the faster the computing speed.

(2) the word length. A set of binary computer at the same time to deal with a computer called the “word”, but this group of binary digits is the “word length”. When other indexes are the same, the larger the word length the faster the computer data processing. Early word length of microcomputer is generally 8 bits and 16 bits. Currently 586 (Pentium, Pentium Pro, PentiumⅡ, PentiumⅢ, Pentium 4) are mostly 32 bits, and most people are now installed 64 bits.

(3)the capacity of the memory. A memory, also referred to as main memory, which the CPU can directly access to, the program to be executed and the data to be processed is stored in the main memory. The size of the internal memory capacity reflects the ability of a computer to store information immediately. With the continuous expansion of the operating system, application software and its functions keep enriching, the demand for computer memory capacity is also rising. Currently, running Windows 95 or Windows 98 operating system requires at least 16 M of memory, Windows XP will need more than 128 M of memory. The larger the memory capacity, the more powerful the system function, and the more substantial the amount of data that can be processed.

These are just some of the key performance indicators. In addition to these key performance indicators above, there are many other indicators. Also, do not isolate from each other between the indicators, in practical application, we should always pay attention to improve the computer performance, these indicators also should be taken together, while following the principle of “cost performance”.

Registry backup is not difficult, in fact, it’s unnecessary to back up the registry, because the system will default to backup the registry every time you start your PC, the default startup item is in the registry entry HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Windows \ CurrentVersion \ Run ScanRegistry = C: \ WINDOWS \ scanregw.exe / autorun, or definitely, backup and restore registry in anytime with a helper.

However, in order to faster the windows start-up, some people will cancel the start-up back up registry key, I strongly recommend my friends here, do retain this key, generally when windows is crash (the registry is modified, o infected virus), it’s very convenient to use this to restore the registry, but I’ve got a better idea, that is, make a registry backup when you think the current system is the most stable and clean one, and then save the backup, once your windows is having problem, restore it with this backup.

Here is the backup method:
Start – Run, type scanregw, then operate in accordance with the prompts, the backed up file can be found in the folder Sysbckup under the system directory, NOTE that, Sysbckup folder is hidden (system directory defaults to C: \ WINDOWS) find several Rb00 * .cab files, the default is five backup files, if you can not determine which one is your backup, then delete all the Rb00 * .cab, and then back up again right from the first step, a Rb00 *. cab file will appear, in order to prevent being overwritten by another backup file, copy it and save it to elsewhere, such as D: \

Recovery method:
When start up your system, hold pressing the ctrl key, enter the menu, select the fifth state to enter the dos statement and enter SCANREG / RESTORE, then Choose a normal start date in the example table file, enter, wait a bit, follow the prompts to restart your PC, registry backup restored.

For today’s internet companies, their future performance and developing prospect are directly related to the digital living habits of the young. Especially under the mobile Internet circumstances, young users are prompting the situations in social networking, games, e-commerce and other areas.

The famous investment bank and capital management company of America, PiperJaffray, does a survey every half a year towards teenagers’ consuming and Internet using habits. The company recently published the 28th semi-annual survey report, which shows Apple iPhone is still the favorite intelligent cellphone of American teenagers. In addition, their interests in old social networking like Facebook and Google+ are decreasing, while Instagram has become their new love.

This survey found that due to the growing employment rate of teen group, their consuming level has also risen.

Apple iPhone holds the leading position among the most favorite digital devices of teenagers. This autumn, two-thirds of American teens have iPhone, which is 6% more than last year.

Besides, 73% expressed they hope their next cellphone could be iPhone.

In the global market of intelligent cellphones, Android and iPhone account for 8: 2. But in teenagers’ heart, iPhone still comes first due to its cool elements.

The report also shows teenagers are losing their interests in mobile games, whose users percentage has decreased to 80%. Yet these players would be more devoted to those games, for example, 22% of them would like to buy virtual goods to pass a higher level. This percentage increased by 4% compared to that of this spring.

Among all the famous social networks, Google+ is the last one covering only 12% of teenagers. In other words, there is only 1 using it in 10. The coverage rate of Google+ used to reach 29%, but now it has lost two-thirds users.

Moreover, there are 8% of teens not using any social networking.

According to sources familiar with the matter, the online retail giant Amazon is planning to open its first physical retail stores.

The source said that this physical retail stores will open at 34th Street in Manhattan, New York, and will begin operating in the United States the holiday shopping season. Prior to this, Amazon has been relying on highly competitive pricing and fast delivery of goods and services to establish and develop their own business, but in terms of the immediate goods-buy have never been able to be compared with the traditional retailers. This physical retailer store function will the equivalent of a small warehouse, only offer delivery service and product refund within New York City in same day, and its limited stock. In addition, the store will accept online orders.

Besides, sources said Amazon would also use for this store for inventory display space, especially Kindle e-book reader, Fire smart phones and Fire TV set-top boxes, such Amazon’s own production facilities will be shown.

So far, other details about the store is still unknown, such as the store size, lease length and inventory quantity. The source also said that Amazon may change plans, and noted that the store is “experimental“for Amazon to enter the retail sector entity, it may not succeed; but if they can succeed, then Amazon may open more in other cities in the United States.

Another source said that in fact Amazon has been planning to open the physical store for many years, or even considered the stronghold of the shop in Seattle two years ago, but the plan ultimately ended in abortion. Amazon has sold Kindle at Wal-Mart and Target’s retail stores, but these retailers have removed Kindle out of the shelves two years ago, it is clearly that they are concerning about Amazon’s growing strength in retail sector.
