"Hillis OS is an attempt of mine to make a web-based desktop..or webtop.OS stands for Operating System. Although 'HOS' is not a real OS, It can do just about anything a real one can. The reason HOS is not "real" is because it is totally web based and it needs a real os, which can connect to the web, to be accessed. What is the advantage? Since HOS is on the web, the user can connect to it from ANYWHERE in the world. Sure, you could do that with a PC, but it would cost you a arm and a leg. Did I mention HOS was FREE. When completed, the system will be available for users to install on servers. Assistance will be available for users unfirmiliar with the proses. Simply put, Hillis OS is a web-based mobile computer which can be accessed anywhere in the world where a internet connection is available."
Details:
Hillis OS works on both Windows and Linux servers that have php and MySQL installed on them. It is coded with php and JavaScript, along with HTML and CSS of course.
