Tell about some recent computer News

The Center for Open and Sustainable Learning(COSL) have made the Microlibraries projects. This projects supply more than 20,000 Project Gutenberg books by a print-on-demand system, which is so simple and cheep. The Center plans to provide 5,000 books for elementary schools in rural area because those schools have a difficulty to stock a variety of books in the school. Therefore, if schools request some books, microlibrary can print books. Moreover, when we access the web site, we can find the books in a print-ready format, so it is convenient. In order to print and bind the books, a computer, a duplex printer, a binder, and a paper cutter are required. These equipments are cost less than $2500 in total. It is possible to save money by bind books manually since a binder costs the most. COSL aims to decrease the cost to a dollar a book in the future.

What Is "Social Engineering"?

Social engineering is a technique to get people’s important private information; for example, passwords for entering some networks, which relate to the security. People who do social engineering get the information by listening to the information secretly, looking victim’s act of typing password from the back of the victim. Moreover, they try to find some private information that would be the key of password from documents which are thrown away in an office. In addition, there is a way to deceive people and enter the network. People who do social engineering pretend to be a customer or user of the network, and they call the manager to change the password. Then, they ask for the new password. All in all, social engineering takes advantage of people’s unawareness of protecting their private information.

I did not know this term before I researched it. However, now I could understand the meaning. At the same time, I realized that I should be more careful about protecting my private information.
