1. The origins of AOP technology
The birth of AOP technology was not too late, and as early as 1990, researchers from Xerox Palo Alto research Lab (i.e. PARC) analyzed the limitations of object-oriented thinking. They have developed a new programming idea that may help developers improve productivity by reducing code-duplication modules. With the deepening of research, AOP has gradually developed into a co

Wireless network technology has come into our lives, in the face of various network technology, how should we compare it? Here is a detailed introduction for us. Wireless access technology is different from the cable access is one of the characteristics of the standard is not uniform, different standards have various applications. Because of this, the wireless
Recently, I saw at the Micro-blog @ Programmer Shanxin Teacher issued a micro-blog-"A lot of college students have an idea: first to do a few years of technology, then do management; Some students said: I am not technical, I hope to directly find a management work, like PM. Please see PM what kind of ability: (link omitted). In reading the previous part of the microblogging, my first reaction is: Do students think that the technical management does no
After the end of the short contact with WAP, wireless applications finally ushered in the real sense of the climax. See how comfortable these wireless internet people are in the photos, and know that wireless networks have come into our lives in a lightning-swift way. But what is the sanctity of wireless networks? What is the status of its application in China? How will it change our network usage habits? And what is the future?

One day to eat with friends just to talk about this topic. As architects or technology developers, when developing software, we are basically playing the role of God: not only do we create a program, we also allow these programs to run independently of our hardware to serve the communities that the program serves. When this program has problems or even bugs, we have to play the role of pastor to fix these problems. Isn't it just a program of society?

The origins of template and JSPs also go back to the ancient days of web development, when people used CGI to develop web apps and write HTML tags in a CGI program.
After that the world began to move in a different direction: Sun offered a servlet solution similar to CGI, but both CGI and servlet faced the same problem: writing HTML tags in a program is not a sensible solution anyway. Sun Company introduced
