Binary Left Shift

"IT168 Technology" some time ago I mentioned in another article that I would like to take the position of broadcasting ideas and develop follow-up mobile solutions. The problem at the time was that I couldn't get rid of the phone to get location information, or a way to make location data useful. 　　In this article, I'll show you how to get GPS coordinates for your phone. Even if your phone doesn't have a built-in global positioning system. 　　Why is it so difficult to locate? The speed at which telephone technology matures is staggering. At present, a large number of mobile phones are built into the Global Positioning system, "smart" mobile phone numbers ...

First, des algorithm in 1973, the U.S. National Bureau of Standards, in addition to the Ministry of Defence of other departments of the computer system data encryption standards, on May 15, 1973 and August 27, 1974, two times to the public to solicit encryption algorithm announcements. The purpose of the cryptographic algorithm (commonly referred to as the DES cipher algorithm requirement) is the following four points: ☆ provide high quality data protection to prevent unauthorized disclosure and undetected modification of data; ☆ has a considerable complexity, so that the cost of deciphering more than possible benefits, but also easy to understand and master;

Absrtact: In 1971, physicist Leon Chua proposed the concept of a fourth integrated circuit basic component element. He believed that, due to the symmetry, the new components would be created and added to the existing three kinds of element resistors, capacitors and sensors. When 1971, physicist Leon Chua presented the concept of a fourth integrated circuit basic component element. He believes that because of symmetry, new components will be created and added to the existing three constituent elements-resistors, capacitors and sensors. At that time ...

There are fewer people playing "World of Warcraft". This is not the author's subjective assumption. Its earnings in the first quarter of 2013, which still retain 8.3 million of the world's most-paid players, have plummeted by 1.3 million compared with the previous quarter. World of Warcraft has a glorious history and is not far away. The game, which was born in 2004, was a stunning record for 13 million of paid players in October 2010. Not only that, Asian players and European and American players are almost half the same. As a cultural product, "Warcraft" successfully across the walls of things and civilizations, creating ...

Now playing "World of Warcraft" has become less and less people, this is not the author's subjective assumptions. According to Blizzard's first quarter 2013 earnings results show that while still retains 8.3 million paid players, ranking first in the world, but compared with the previous season, has suddenly dropped 1.3 million. World of Warcraft has a glorious history, and not far away. This super online game was born in 2004 and hit an astonishing record of 13 million paying players in October 2010. Not only that, Asian players and Europe and the United States almost half each player. As a cultural production ...

For years I've been worried that the open source movement might suffer from Kim Stanley Robinson's brilliant exposition of "Green Mars": "The tide of history is faster than we do."   "Innovators are left behind, and the world they've changed is running in unexpected directions with their ideas." In the "Open source paradigm shift" and "What is Web 2.0" These articles I think the internet as a private platform mainly built on the open source software, its success is likely to lead in the field of cloud computing ...
