1.Team Name: BESTRWWorks: Barter AppAddress: http://www.cnblogs.com/niceRW/p/5117667.htmlReviews: The software design is very good, the interface is concise and clear, but the commercial software to consider the success of the factors are still quite a lot of, such as competitiveness, and salted fish app is very simple, so users will not be too much.2Team Name: OurteamWorks: Genius WebAddress: http://www.cnblogs.com/ourteam/p/4204670.htmlComments: The function is very full, the interface design

translation, reported (new breakthroughs in machine translation) is: Google's Tomas Mikolov team has developed a dictionary and glossary of automatic generation techniques that can turn one language into another language. This technique uses data mining to construct a structural model of two languages and then compare them. The set of relationships between words in each language is a "language space" that can be characterized as a vector set in mathematical sense. In vector space, diff

How the View works Basic concepts Viewrootcorresponding to the Viewrootimpl class is the link between WindowManager and Decorview, view of the three processes are through the viewroot to complete, in Activitythread, when the activity object chant was created, The Dectorview is added to the window, the Viewrootimpl object is created, and the Viewrootimpl object and the Dectorview object are associated, referring to the following source code

Knowledge Points:Von Neumann architecture, its core idea is to store the program computer.The CPU is connected to the memory via the bus, and the IP pointer takes one instruction from the memory in turn.API: interface between programmer and computer.ABI: interface between program and CPU.Registers, addressing methods and various directives have been thoroughly understood in the study of "in-depth understanding of computers" and "compilation".Experiment:Into the following:The original code is:int

How Rsync works Data transfer between a single host local (this is similar to the functionality of the CP command). With the RCP,SSH equivalent to the arrival transfer data (this time resembles the function of the SCP command). Transfer data as a daemon (socket) (This is an important function of rsync itself).

how the graphics card works　the data after the CPU processing must undergo the following 4 steps before it reaches the display:1. 　From bus to GPU (graphics processing Unit, graphic processor): The data sent by the CPU is sent to the North Bridge and then sent to the GPU (graphics processing device) for processing. 2. 　Enter video RAM (video memory) from video chipset (graphics chipset): The data processed by the chip is sent to the video memory. 3. 　

Today I and I good friend Ah bin by exploring the source of Struts2, summed up its principle, code is not deceptive.Overall: Struts works in 7 steps:1 The client initializes a request to the servlet container;2 This request passes through a series of filtersWhen the project is deployed, the Web. xml file of the project is read by the Tomcat container, and the Web. xml file is tested as follows: web-app version="2.5"xmlns="Http://java.sun.com/xml

Http://www.cppblog.com/woaidongmao/archive/2011/06/21/149092.htmlWhat is fastcgi?FastCGI is a language-independent, extensible architecture for CGI open extensions whose main behavior is to keep the CGI interpreter process in memory and thus achieve high performance. As we all know, the repeated loading of CGI interpreter is the main reason of poor CGI performance, if the CGI interpreter remains in memory and accepts the FASTCGI process manager scheduling, it can provide good performance, scalab

How the Iptables firewall worksIntroduction: Iptables firewall works at the network layer, filtering and restricting TCP/IP packets, iptables firewall based on kernel coding, with very stable performance and high efficiency;Iptables belongs to "User State" firewall management system.Rules tableFilter Table: The filter table is used to filter packets, according to the specific rules to decide how to process a packet. Corresponding kernel module: Iptabl

HDFs is a highly fault-tolerant system that is suitable for deployment on inexpensive machines. It provides high-th

corresponding data is stored separately. General-purpose registers are widely used and can be prescribed by programmers, and the number of universal registers varies by microprocessor. This is our future to introduce this point, here first mention.We will refine it, and we can draw a summary of how the CPU works as follows: Generally speaking, the CPU takes out the instruction and the corresponding data from the memory, and according to the instructi
