platform-independent.Here is the main concern is the Eigen3/eigen folder, the folder below is the Eigen source code, that is, we need to add the header file directory.In the Eigen3/unsupported folder under the Eigen folder, is eigen some of the extension features of the code, if necessary, you can also add this header file directory.Here I am using Vs2012 to do the test, after creating an empty project, configure the project properties, here I only add the path of the core code of Eigen.third,

V8 (Google Chrome's JavaScript engine), node. JS is based on the JavaScript runtime environment on the V8 engine and can be seen as a more abstract JS engine.node. JS uses an event-driven, non-blocking I/O model. (non-blocking I/O:I/O operations do not block the execution of the program, while the I/O operation continues to execute other code.) Event-driven: Each asynchronous event generates an event watcher that invokes the appropriate callback function if an event occurs, or the request comple

the blacklist.Explain the above URL, "posts": it is generally referred to as the controller, which determines which processing file to load; "index": it is generally called an action, which determines what to do. So/posts/index/as the name implies is posts homepage. If you need to pass parameters later, you can add them directly behind the action.As in the following url:http://www.nostop.org/index.php/posts/category/1/. Lists all content under the category ID of posts 1.Some of the frameworks i

execution path, also known as the execution scenario.Can there be no threads in a process? Impossible, the space to open up, to run the code is here, no content to help you execute, the program will not run up.Known as the execution path, it feels more unfamiliar.See, not only the left in the execution, the right is also executing, while in operation, this is multithreaded, there are multiple execution paths at the same time running.The presence of a thread can be responsible for program execut

Overview Have you ever used to find *.tmp temporary files? Have you ever used the Find/Replace feature in the editing tool? In fact, they all use regular expressions The role of regular expressions Provides more powerful string processing capabilities To test patterns within a string For example, you can test the input string to see if the phone number pattern or the ID number pattern appears within the string. i.e. data validation Replace tex

Overview of struts1.x Tag Library Struts's tag library is divided into the following five categories: 1.HTML Tag Library The custom tags in the HTML tag library are typically one by one corresponding to the tag in HTML. such as 2.Bean Tag Library The custom tags in the bean tag library are primarily used to output text information to the client. So why does struts have to provide a single tag library to output text messages to clients? There are

Oracle Profiling Functions Overview Profiling functions in Oracle are similar to aggregate functions, but for each set of records, no matter how many rows, the aggregate function returns only one row of values, and the parse function returns a value for each row of records. This set of records, called the Parse Function (window), determines the scope of the data to be processed, which can be physically determined by the specified number of rows, or l

Overview Aspect-oriented programming (AOP) is an exciting new specification that has the same effect on software development as the more than 10-year-old object-oriented programming (OOP). AOP and OOP are not competing technologies, and in fact they complement each other very harmoniously. Object-oriented programming is useful for modeling common object hierarchies. The disadvantage of this is that it deals with common situations across multiple unre

read the fsstnd to get a full understanding. This chapter does not explain all the files in detail. The intention is not to describe each file, but to give an overview of the system from the perspective of the file system. More information on each file is in this manual or elsewhere in the man page. The intent is to divide the entire tree into smaller portions, each of which can be on its own disk or partition, to accommodate disk capacity and easy t

The Java API native supports IO operations. Java IO is primarily designed to read (input) and write (ouput) data.Most programs need to process some input data (such as file data, network data, and so on) and produce output based on these input data. Here are a few scenarios where we often encounter:1. The compression software needs to read the file to be compressed and output the compressed file to another file.2. When accessing FTP we need to read the network data (using the FTP protocol to rea

strong references (strong Reference), soft references (softreference), weak references (weakreference), virtual references (phantomreference), and references are strong to weak. A strong reference is a common in code, similar to a reference to the object obj = new Obeject () class, which is never recycled Soft references are used to describe something that is also useful, but not necessary, before an exception is thrown when a memory overflow occurs and a soft-referenced object is reclaimed two
