What is HTTP Proxy?
HTTP proxy is a method to connect to a website by through an intermediate “proxy” server. The way it works is that your browser sends the request for a web page to the proxy server. The proxy server then forwards the request to the website. The website sends the requested page back to the proxy server, which in turn sends it back to your browser.
Uses of HTTP Proxy
HTTP proxy is most commonly used in two cases: (1) you want to fake your identity to the website; and (2) you want to bypass a firewall.

“Stealing the Network: How to Own a Continent” is an interesting technical hacker story. Even though the plot of the story is not very well connected, the authors develop the story using real technology to compromise computer networks, which makes you feel that this is not just a fiction and it might be actually happening somewhere in the world right now.
The book shows the intuition of people who became hackers. It also shows how the hackers’ business works and how they communicate. Many various kinds of hacking techniques and tools are mentioned ranging from social engineering, several kid hacking tool, and good (or I should say bad) uses of available legitimate resources. The authors show how hackers collaborate and make use of different types of networks and security holes to help them accomplish their goal.

Overview
The UNIX grep utility marked the birth of a global regular expression print (GREP) tools. Searching for patterns in text is important operation in a number of domains, including program comprehension and software maintenance, structured text databases, indexing file systems, and searching natural language texts. Such a wide range of uses inspired the development of variations of the original UNIX grep. These variations range from adding new features, to employing faster algorithms, to changing the behaviour of pattern matching and printing.

All you need to know about managing Linux/UNIX/BSD.
At first glance, this book seems like a typical O’Reilly book: a narrow title, rich in material, and is beneficial to a much wider audience than the title reveals. It covers a wide range of system administration subjects and goes way beyond just the essentials.
Over the years, I have administered several multi-user UNIX, Linux, and FreeBSD servers. I believed that I knew the essentials, because if I did not, I would not have been able to do my job all these years. I wanted to see if the things that I learned by experience, often the hard way, are included in “Essential System Administration”. Sure enough, they were all there. Not only that, but they were laid out simply, without much unnecessary technical details, and accompanied by numerous examples and anecdotal encounters by the author. If you read one section, you would be able to apply the knowledge and skills that it describes right away. For instance, you don’t need to read the entire manual of procmail in order to write some effective mail filters; chapter 9 has a section on “Mail Filtering with procmail” that covers the essentials.
