Torvalds Explains Scheduler Decision

Firedog writes "There's been a lot of recent debate over why Linus Torvalds chose the new CFS process scheduler written by Ingo Molnar over the SD process scheduler written by Con Kolivas, ranging from discussing the quality of the code to favoritism and outright conspiracy theories. KernelTrap is now reporting Linus Torvalds' official stance as to why he chose the code that he did. 'People who think SD was "perfect" were simply ignoring reality,' Linus is quoted as saying. He goes on to explain that he selected the Completely Fair Scheduler because it had a maintainer who has proven himself willing and able to address problems as they are discovered. In the end, the relevance to normal Linux users is twofold: one is the question as to whether or not the Linux development model is working, and the other is the question as to whether the recently released 2.6.23 kernel will deliver an improved desktop experience."

Linus, Games are important!

[12357bd]

The only important points to me are:

1) Games are basic to linux desktops, we need linux games, so if Con scheduler was best on games, please, incorporate those changes.

2) EGO's are a pain in the ass, it seems that Con has been refused by Linus , because he didn't take the whole history into acount, too bad, that kind of things happend in any not trivial project management. Don't let EGO's rule the ball, that's the most basic point a manager (Linus) has to respect to keep people on the project.

Word is a commercial software program that many people use to write emails to their mother, colleague or even boss! Some even use it to write letters or even resumes for when they find a job! It is produced by a company called Microsoft that tinkers with computers. Microsoft also produces an operating system you may be familiar with, called Windows.

Most personal computers sold today come with Microsoft Windows already installed so you don't have to do anything, except find software useful to you. Just connect to the computer to the internet via the phone line, and download the first program that advertises on your computer for free! Or you can use Wordpad.

Back in the early 1990's, a man name Linus Torvalds wanted a operating system that he could use that was similar to Minix, but he could change when ever he liked! (Yet another operating system! Yes, there are many! A lot are based on a very old but operating system called Unix. These are called 'nixes. Minix was one that was used for education purposes mostly. Rather old now, so don't worry about it. You may come across some called BSD; these could be interesting to you.) He wrote another kernel that was similar to Minix and uploaded it to the internet. Some friends of his thought it would be cool to call the kernel 'linux'. Since then many people have worked with the kernel to produce operating systems known as Linux.

Soon after, many people who didn't like Microsoft's Windows began using Linux instead. Many people also began modifying the operating system to do what they personally wanted. Often they would tell people, "This is what I did, if you like it, use it and improve it. But you have to let everyone else do the same with your modifications." This became known as Open Source.

The programs that these Open Source people use to write emails or even resumes often have really long names like v, ed, Emacs, nano, vim, kate, kwrite, gedit, openoffice.org writer, staroffice, and many others. It would have taken too long to use one or more of these names, rather than type the qualifier GP tacked on.
