Today, I was very busy. I wanted to write more content. There is no way to do it now. I have to pick up a simple component and write it down. I will introduce the components in the following chapters.

When I came home quietly, the teacher was lying on the couch in front of the fireplace looking at a thick old book with a dark red cover. When he saw me, he quickly stuffed the book to the mat. Unfortunately, I still saw it.

2. google-based V8 javascript interpretation engine is very fast. As a server language, it may not be the fastest, but it must not be slow.
3. asynchronous + callback operations make the Node. js server highly concurrent
4. The npm and the community are huge, and the third-party libraries of Node. js are unimaginable.
II. Introduction to express

JDK built-in log system and jdk built-in log
1. Log functions in Java applications
========================
Generally, Java applications require logging. Currently, the mainstream log recording method is to introduce log4j in the application and use log4j to generate logs. In fact, JDK has its own log system, which is easy to use.
2. Use of Java built-in logs
========================
Classes related to the jdk built-in log system are included in the java. util. logging package. The following ex

These unnecessary modules are making our programs bloated and bulky. Obviously a little web if you do it with MVC, you'll find that using PHP or directly with ASP. NET PAGES will be much faster than that. It is possible that Owin is a trend in the future of ASP. As a developer we have the right to determ
Log4cplus is excellent in many aspects, but it is uncomfortable to use it in some places. I'm not happy with it until I continue to talk about it.I will mention it a little and continue to introduce the knowledge about threads and sockets.
### Some improvements ###
1. The implementation mechanism of user-defined loglevel is not open enough
In article 5, I have introduced how to implement custom loglevel. To achieve better results, I even need to change log4cplus.Source code. :(
2. The mechanism

3.1 log category hierarchy (loggers)
The primary advantage of log4j over the simple use of the system. Out. println () method is its ability to disable some specific information output without compromising the output of other information. This capability is derived from the
Log output is a prerequisite for all systems, and many developers may not be able to relate to the JDK logging modules because they often use log4j. What is the connection. How the JDK logging handles the details. This week, first analyze the JDK logging mechanism. * * Starting from the example
