Not many of use who use the web these days type http:// before typing in the URL and Google has decided that they don’t need to display the Hypertext Transfer Protocol (http) in the address bar no longer. Google has made this official because they made the move without informing developers and some developers reported it as a bug. Is this a sign of whats to come for browsers? I see that this could cause a problem for users that copy the URL and paste it as a link or in another browser.  I guess this is why Google has only made this change for the developer version.

Hello World program is used because it is the simplest in any computer program language and it is very easy for anyone to understand. Hello World was first used by Brian Kernighan, 1972 in his “A Tutorial Introduction to the Language B”

Language B was written at “Bell Labs” and was replaced by the language C. Hello World program was also featured in the book  C Programming Language (2nd Edition). Language C has been the influence for many of the computer programing languages that are used today.

Since “Hello World” was written by Brian Kernighan web design and development students across the world have been writing computer programs in html, PHP, Java, JavaScript, C#, and many others displaying “Hello World”.
