QWERTY-keyboard when this idean came

By
QWERTY QWERTY   / ˈ k w ɜr t i /  is the most common modern-day  keyboard layout . The name comes from the first six  keys  appearing on the top left letter row of the keyboard and read from left to right: Q-W-E-R-T-Y. The QWERTY design is based on a layout created for the  Sholes and Glidden typewriter  and sold to  Remington  in 1873. It became popular with the success of the Remington No. 2 of 1878, and remains in use on electronic keyboards due to the  network effect  of a standard layout and a belief that  alternatives  fail to provide very significant advantages. [ 1 ]  The use and adoption of the QWERTY keyboard is often viewed as one of the most important case studies in  open standards  because of the widespread, collective adoption and use of the product. [ 2 ] History and purposes [ edit ] Keys are arranged on diagonal columns, to give space for the levers. Main article:  Sholes and Glidden typewriter Still used to this day, the QWERTY layout was devised

robot.txt what is this and how to use this

By
What do they do exactly? Robot.txt files tell your instructions to a search engine robot.. The first thing a search engine spider looks at when it is visiting a page is the robots.txt file. It looks for it because it wants to know what it should do. If you have instructions for a search engine robot, you must tell it those instructions. The most common problem people have with robot.txt files is that they don't know how to make them. If you can make web pages, you can also make a robot.txt file. The file is a text file, which means that you can use notepad, wordpad, or any other plain text editor. You can also make them in Frontpage or Dreamweaver by using the "code" view. You can even "copy and paste" them. So instead of thinking "I am making a robot.txt file", just think, "I am writing a note" they are the exact same process. However you would write a note or a letter on your computer will work for the robot.txt file. What should

Google Doodle how its born

By
About Doodles More Doodles Home About Doodles Doodle Store Doodles are the fun, surprising, and sometimes spontaneous changes that are made to the Google logo to celebrate holidays, anniversaries, and the lives of famous artists, pioneers, and scientists. How did the idea for doodles originate? In 1998, before the company was even incorporated, the concept of the doodle was born when Google founders Larry and Sergey played with the corporate logo to indicate their attendance at the  Burning Man  festival in the Nevada desert. They placed a  stick figure drawing  behind the 2nd "o" in the word, Google, and the revised logo was intended as a comical message to Google users that the founders were "out of office." While the first doodle was relatively simple, the idea of decorating the company logo to celebrate notable events was born. Two years later in 2000, Larry and Sergey asked current webmaster Dennis Hwang, an intern at the time, to pr
