beginning of this book, I must say: This book owes me a lot of debt, it owes a lot to those who have done a lot of research work over the past decade and created a reconstruction field. This book should have been written by one of them, but in the end it was cheap for me who had time and energy.
The two earliest advocates of refactoring technology are wardcunnhan and kentbeck. They have long taken refactoring as a core component of the development process and used it in their own development pr

Llvm projects are a collection of modular and reusable compiler and toolchain technologies. Although its name, llvm, is not big for traditional virtual machines, it does provide useful libraries for building them.
Llvm started a research project at the University of Illinois, with the goal of providing a modern, SSA-based compilation strategy that can support both static and dynamic compilation of any programming language. Since then

Finally, it tells how Netscape created the Internet boom for 90 years. For other chapters in this series, see the first and second sections of the 50-year Oral History of the Internet.

Squid problem! I 've been working on it for several days, so I 'd like to come up and ask my brother-Linux Enterprise Application-Linux server application information. Here is the details. Dear friends, I encountered some problems when configuring SQUID. Please give me some advice. My configuration file is as follows:

ANDREW: if there is a lack of good leadership, it is more dependent on collective leadership. Do you think this may lead to a great team?
TIM: possible. But pay attention to it. Apache is a good example. Tim Berners-Lee made a blueprint and said, "I have thought about it, that is, hypertext server and hyper-text client ." Apache talents are willing to accept such constraints. I also remember that in the middle of 1990s, Netscape added something. Microsoft added someth

Mod_php and fast-cgi are capable of processing multiple requests during the lifetime of each process, while CGI mode processes a request to destroy the process immediately, and CGI performance is very poor in high concurrency scenarios.

In the beginning there was NCSA Mosaic, and mosaic called itselfNcsa_mosaic/2.0 (Windows 3.1), And mosaic displayed pictures along with text, and there was much rejoicing.
And behold, then came a new Web browser known as "Mozilla", being short for "mosaic killer," But Mosaic was not amused, so the public name was changed to Netscape, and Netscape called itselfMozilla/1.0 (win3.1), And there was more rejoicing. and Netscape supported frames, and frames
History and prospects of the first stop Apache
In 1995, a developer of the National Computer Security Association (NCSA) created the NCSZ global network service software. Its biggest feature was the HTTP genie program, it was easier to configure and create the source code than the CERN server at that time. Due to the lack of other server software at that time, it soon became popular. But later, almost all core developers of the server left
what is CGI
CGI is currently maintained by NCSA, and NCSA defines CGI as follows:
CGI (Common Gateway Interface), a universal Gateway interface, is a program that runs on a server such as an HTTP server, providing an interface with the client HTML page.
Web browsing
To get a better idea of how CGI works, we can click on a link or URL from the Web page:
1. Use your browser to access the URL and connect to t
tell the browser to request the server which port is the service. That is, write "http://your.host.name: 8080" can connect to the other side of the port 8080;
2. Types of www host systems;
Generally, there are two types:
One is the Windows system's IIS + ms SQL + ASP WWW server, which is relatively easy to assume on the www host, but due to some features of windows, it is easy to be damaged by hackers;
The other is the www server (LAMP) of Apache + MySQL (PostgreSQL)
://www.dwz.cn/yFFgQ)Initially, CGI was developed in 1993 by the National Supercomputer Application Center (NCSA) for the NCSA HTTPd Web server. The Web server uses the UNIX shell environment variable to hold parameters passed from the Web server and then generates a separate process to run the CGI. The CGI processing flow is as follows:L Step1. The Web server receives a request from the client (browser), in
