Of course, as your microservices system gets more complex, you'll need a lot of other spring cloud components and other technologies. But if you und

Windows also has sketch to use! Two days ago, Adobe family Bucket just joined a new product called Adobe Experience design CC, today @ Asphyxiation Red Leon brings everyone to experience the preview version of the various features. Last year Adobe released an introduction and video of Adobe Project Comet on its web site, which is now available for download to the Preview version of the trial, with the current version renaming the software to XD (the file format is also. xd), the inexplicable po

With the development of computer network technology, Wireless LAN has become a high-speed development of wireless communication technology in the computer network to achieve communication mobility, personalization and multimedia applications. However, because the transmission media of wireless communication is the air with no entity protection, the data sent by wireless can reach all the terminals within the coverage range, or it is an unexpected receiving device, which provides more and more co

Today just opened a blog, hope it accompany me to grow together.The next time to complete the small project of the Java chat. Today, we have a brief look at the technical content that needs to be used.1. To save the chat data, you need to use the database2. To receive and send messages, you need to use the network3. Maintain network connection, need to use thread4. The chat will also need to have an interfaceThe above is a rough technical content, but also to understand the client and server sid

concept >serialization (serialization): Converts the state information of an object into a process that can be stored or transmitted over a network , in the form of JSON, XML, and so on. deserialization (deserialization): is to read the state of the deserialized object from the storage area (json,xml) and recreate the object.JSON (JavaScript Object Notation): A lightweight data interchange format that is easier to read and write than XML, is easy to parse and generate, and JSON is a subset of Ja

language, assembly instruction is the mnemonic of machine instruction, Each assembly instruction has a corresponding machine instruction, which is a great boon for programmers, who do not need to remember the boring 01 sequences. The advent of assembly language does largely liberate programmers, but what we need to know is that computers only know 01 sequential columns, machine instructions, We do not know the assembly instructions we write, to enable the computer to perform the assembler we h

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
