Origin - Create micro-blog in English-Chinese dictionary, Twitter verb meaning: 1. (Birds, etc.) twitter, chirp, and singing out; 2. Twitter about and, by extension for everyone to share the expression of desire and want to . Twitter and the company's logo is an image of a blue bird twitter.

Twitter by Evan? Williams, who co-founded. In 2006, this San Francisco-based company in the United States launched a Twitter service, in March 2007 started.

Twitter is primarily a site, the site home page prominently visible text in its role with a brief description of the effect that: Twitter is a service that lets you and your friends, family, colleagues to maintain close links. Through such contacts and exchanges at any time, and you can quickly get an answer. The problem is that it appears so often in life one of the issues that we are most concerned about are often the most eager to get answers to questions. That is - Twitter: What are you doing?

From this profile is not difficult to see, Twitter is a service, the service is based on the currently very popular Web2.0 model, that Twitter provides an Internet platform, from which the participants self-organized content.

Twitter's roughly the way they operate is: Any Twitter users to upload not more than 140 characters per message, the user corresponding "follower" (followers) will be able to view the information and timely comment. The so-called "follower" refers to an account published by concern about the content of other Twitter users. Of course, users can also take the initiative to "follow" (following) other people. It is by limiting the number of words of information, real-time arrival, user send and receive and identify the authenticity of their own way to achieve an autonomous, interactive, simple and rapid information dissemination.

Development - Twitter election show their skills in the 2008 U.S. presidential election on their mettle, many Twitter users regarded as essential to the success is the Obama campaign one of the factors. In the general election, some candidates who use Twitter publish your own itinerary, including Obama and Hillary are in Twitter to create a personal home page.

Obama's Twitter page is well designed, put head in the usual place, put the election is his mark. His picture on the background at, and even flip the page from top to bottom is always displayed in the upper left corner. Right-hand column shows the bottom of the page were the followers of the small icons.

Obama finally received a 15-million "followers" support, while Clinton's "followers" less than 6,000 people. Note that the Obama people over the track following his people ( "Following me" 135229 people, "Followers me" 131151 people), the difference between a 4,000 or so. This shows that he was actively concerned about a number of other people, and not just passively "reciprocity."

Against what Clinton's Twitter, "Following me" as 0, "Followers me" 5996 people. Not only the nearly 6000 followers can not be compared with Obama's more important difference is that Clinton's following number 0! In the left column, and no Followers of the small icons. Twitter's secret is that you are concerned about the number of people, rather than the number of people are concerned about you, to as much as possible to follow more people, it is a very good access to information from others sources. The Clinton's Twitter is just an information publishing platform, not a communications tool, or that she was not concerned about those concerned with her. Could show off to listen to public opinion, attitude, Hillary has released its own journey into an place where chess is indeed poor compared with Obama, a forward.

During the campaign, Obama has tasted the sweetness Then it was announced after the White House home page on Twitter to show the People First. In addition to his, the United States there are about 1 / 5 of members of Congress registration Twitter. In the Anglo-American politicians, the British Secretary of State for schools and families Ed? Bowles, London Mayor Boris? Johnson is Twitter's loyal users. According to the latest media reports, even the always abide by the tradition of the times of the British royal family refused to have opened a Twitter page. In addition, many European and American entertainment, sports stars were settling on Twitter.

Use popd top of the directory will be deleted, and then jump to the next in the list a directory. Try this command, the management system when you need to jump between different directories or when the location is easy to forget important things, it might be quite useful.

But the pkill command can remove a lot of work, pkill firefox you can kill the process in the list of all firefox matching incheng. Pstree is also a cool command, it will in accordance with all relationship to the family tree display all processes.

Add a shortcut on the desktop, enabling novice to obtain a similar experience of Windows, to avoid getting lost in a complex system menu.

7. To accelerate the launch OpenOffice.org

If you frequently use OpenOffice.org, you may be its long startup time to. To solve this problem, open the session process (in the Jaunty been referred to as the boot manager, anyway, you are always in the System-> Preferences-> Startup Applications found), and then add one. In the command line, type openoffice-nodefault-nologo, after restart, OpenOffice will start the Gnome desktop when the cache, re-launch any OpenOffice program will be completed soon.

8. Quick clean up the disk garbage

Not enough disk space on it? Try in a terminal window, type sudo apt-get autoremove and then type sudo apt-get clean, before a command to uninstall the system for all unused dependencies, the latter command will clear all cached package files, both free victims. In an escalation of the system many times, you may be cleared through this method a number of GB of space.

9. To find the missing file extensions

If you receive an email attachment without an extension, do not know what type of time (Mac users often ignore the file extension), try the file command, direct with the file name. At the same time can also try the strings command will show any binary file string can be displayed, normally the type of file will be in front of a few lines, so pipe this command and head is a good way to connect.

10. Do not forget these manual pages

Take a look at these interesting but not well-known manual page: intro beginner's command-line guidance; hier file system description; built-ins do not self-explanatory order a variety of mini-manual.
