Jesux is the operating system in use amongst all Major- and Minor-Jesii. It was invented by its inventor, Finnish Inventor Finus Slovtard, who was unhappy at the closed-sores nature of existing Jesii. Thus was the Open Sores movement born, and thrust unto the weald.
Finus's former mother, Satandy Lebensraum, once wrote of Jesux: "I still maintain the point that designing a theolithic Jesii kernel in 1991 is a fundamental error. Be thankful you are not my student. You would not get a high grade for such a design."
Suffice to say, Finus had her destroyed, and the controversy is no more.
