1. Why are there young generationsWhy do we need to divide the heap? Can't you do what he's done without being generational? In fact, there is no substitute, the only reason for generational is to optimize GC performance. First you think, if there is no generational, then all of our objects are in one piece, the GC when we want to find out which objects are useless, so that all areas of the heap will be scanned. And many of our objects are going to die, if generational, we put the newly created
also caused by a large number of applications in the early stage of release.ProgramThe key cause of incompatibility.
We already know that Windows 7 will still use the main architecture of Windows Vista and will not be re-launched, but will be further improved and upgraded. Therefore, the core version will be 6.1, not 7.0.
Why is it Windows 7?In fact, it has nothing to do with the core code version, just because it is the seventh-generation desktop
QR Code, we also called QRCODE,QR Express response fast response, in many apps we can see the figure of two-dimensional code, the most common is. So today we'll see how to integrate the scanning and generation of QR codes into our own app. OK, no more nonsense, let's start.The use of two-dimensional code I mainly want to be divided into two parts to introduce, part is the generation of two-dimensional code,
In the past two years, the Gan upsurge swept through the AI field top-level meeting, many high-quality papers were published and discussed, in many scenarios have applications. Yann LeCun had judged Gan "the coolest idea in the field of machine learning for 20 years." Gan can effectively solve the problem of creating the natural interpretation data, especially for the generation of high-dimensional data, the neural network structure of Gan does not li
Chinese search engine veteran Chen Yu (CEO) in 2010 put forward the concept of open search, a time in the industry caused a big stir. Open Search is the third generation of search, the first generation of search is the directory of the Yellow pages for the search, the second generation of search is based on Baidu, Google as the representative of the keyword searc
The last stage is the creation of the target code, which is run on the target machine, by the intermediate Code optimization, semantic analysis---syntax analysis, lexical analysis, and so on. The task of the target code generation phase is to convert the previous intermediate code into machine language or Assembly languages on a particular machine, which is called the code generator.

Ai write poetry?? Ai Creative fiction?? In recent years, people often hear this kind of news, it sounds very strange, so today we come to explore how this function is achieved through deep learning.
The basic strategy for text generation is to use a language model, a probabilistic model that predicts the next most likely word based on the input data, and the text as a sequence of data (sequence data), with a context between words and words, so using a

IntroductionThe so-called Maze generation algorithm is the algorithm used to generate a random maze.The Maze generation algorithm is in such a scenario:
A row row, a grid map of Col columns, the first default all the walls around the grid are closed
Requires a 2 wall on the edge of the grid map, which is the edge of the grid.
All grids are guaranteed at least one wall around the grid to get
In a keynote speech with Martin Fowler, he provided a keen observation report:
The legacy of Java is the
platform , not the
language .
The original Java technical engineer had made a great decision to separate the language from the runtime, eventually enabling more than 200 languages to run on the Java platform . This infrastructure is critical to the long-term viability of the platform because the life of the computer programming language is usually very short. Since 2008

Absrtact: Web Development technology is an important aspect of Internet application, and JSP is the most advanced technology of web development, which is the first technology of Web developers. However, because JSP requires a high level of web developers, many general Web developers are not able to use this advanced technology. This paper discusses the design and implementation of JSP Web page automatic generation tool based on t
Why would you want to generate a static page?
This question we do not say more, his advantages only one, greatly improve the performance of the site, for large data volume, visit a large number of sites do not use static page output solution, I am afraid it is unbearable. The disadvantage is not to say, a lot of .... But the single advantage is worth studying. Let's discuss the general processing of the static page generation scheme and the Staticpol
When you create an entity in JPA, you declare the primary key of the entity and its primary key generation policy. We have an entity class called email, whose primary key is declared as follows:
@Id
@Column (name = "email_id")
@GeneratedValue (strategy = generationtype.sequence, generator = "Emailseq")
@SequenceGenerator (initialvalue = 1, name = "Emailseq", Sequencename = "email_sequence")
private long ID;
We use @generatedvalue's strategry field
When creating a database, you need to specify a primary key for each table, which is a property or group of attributes that uniquely identifies a row in a table, and a table can have only one primary key, but there may be multiple candidate indexes. Because a primary key uniquely identifies a row of records, you can ensure that you do not have pigtailed errors when you perform data updates and deletions. There are several ways to generate the primary key of a database, each of which has its adva
As the core technology of the Next Generation Network, Softswitch has become one of the most important topics in the telecom field, whether it is telecom operators, equipment manufacturers, or business developers dedicated to this field, they all hope to use Softswitch technology to promote and develop the telecom service industry, consolidate their own market position, and obtain direct economic benefits.
