Ted Nelson
Short for HyperText Transfer Protocol, HTTP is a set of standards that allow users of the World Wide Web to exchange information found on web pages. When wanting to access any web page enter http:// in front of the web address, which tells the browser to communicate over HTTP.Today's modern browsers no longer require HTTP in front of the URL since it is the default method of communication.The term HTTP was coined by Ted Nelson. -

Dvorak Keyboard
Developed in 1936 and patented May 12, 1936, the Dvorak keyboard has all vowels and punctuation marks on the left side of the keyboard and consonants on the right side. Because of the placement of the keys on the home row and the adaption of the letters to the English language, many users who use the Dvorak keyboard will type faster than users using the QWERTY keyboard. Below is a picture of the layout of a Dvorak keyboard.
