Image files can be copied out, using PYUV software to view YUV pictures. It is important to note that when using PYUV to view YUV pictures, you need to set the image format correctly, according to the data format collected by my code, it is set as follows:

There is such a collection system needs, to achieve the target: the need to collect 300,000 keywords data, micro-blog must be collected in one hours, covering four micro-blog (Sina Weibo, Tencent micro-blog, NetEase micro-blog, Sohu Weibo). In order to save the customer cost, the hardware is a common server: E5200 Dual-core 2.5G CPU, 4 G DDR3 1333 RAM, hard disk 500G SATA 7200 rpm. Database is MySQL. Can we achieve this system goal under such conditions? Of course, if there's better hardware, it

An overview of a series of essays and the resulting backgroundThis series of articles in addition to explaining the network acquisition and the use of a variety of important technologies, but also provides a number of solutions to problems and interface development programming experience, very suitable. NET development of the beginner, intermediate readers, I hope you have a lot of support.Many beginners often have this kind of confusion, "Why I read
With the concept of big data growing, how to build a system that can collect massive data is put in front of everyone. How to do what you can see is the result of no blocking collection, how to quickly structure and store irregular pages, how to meet more and more data acquisition in a limited time to collect. This article is based on our own project experience.
Let's take a look at how do people get Web data?

the similarity plus one. we will k -1=m, where M is the similarity, K is the next array value-->max{k}PJ's next value depends on the prefix p1p2....pm suffix PJ similarity, which is the similarity plus one. So our task now is to find k-1 to find M, look for similarityFor example: Although we can directly see that the similarity of ABAB is 2, you can write a function to get its similarity, and when we ask for the next next value, the string becomes Ababa, we can also see that the similarity
