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."
Everyone except you.

Actually, I have no idea how an OS works and even _I_ know what this article is about.
I'm sorry but the flame wars over whether you call it zee eff ess vs. zed eff ess would make the vi vs. emacs flamewar look like a watergun fight. It would likely tear the Linux project apart as radical Zeddites suicide bomb the Zee Alliance.
Look at the front page much?
Do you even lift?
These aren't the 'roids you're looking for.
Come on, it's quite obvious that Linus's secret superhero alter-ego has done battle with Kolivas' supervillain identity before (I mean, Con Kolivas? Do the writers even try to make these things sound authentic?) and is now trying to thwart his evil plans of global domination.
Hehe, ;) you are right. Their ProTools hardware just has to be better, because it costs so much :)
The scheduler is reponsible for deciding which programs can use the processor when. So, lets says you're running Word (not likely on linux, for quickest example I could come up with), and Word is for some reason using 100% cpu. Well, depending on how the scheduler works, that is how the cpu is shared between processes, other applications might continue working ok, or might freeze up entirely whilst they wait for Word to finish.
So, the scheduler controls how well different applications work together at the same time.
You're going to love this Theo guy, then.
I keed, I keed.
Dewey, what part of this looks like authorities should be involved?
Well, your scheduler certainly wasn't fair on that one.
Anybody want to claim themselves as an AFLAC (Anonymous Finnish Latin-American Coward)?
More like Surf's Up, but with emphasis on kernel development, instead of surfing. By the way, stay tuned for Dreamworks' Pictures "Tux". An animated comedy, starring yet even more penguins, and the lovable little guy himself. Tux is an ordinary penguin, working away at his operating system all day, like good penguins should. A chance meeting with the BSD Daemon and Gnu marks the start of a grand adventure that takes Tux all over the internet (including a brief visit to Slashdot itself). Tux makes friends with a host of colourful characters, meets the girl of his dreams, and learns an important lesson in process prioritization and task scheduling.
Unlike porn, which yada yada rimshot hey-ooh!
Nah, Linus is right to be tough. The ability to take a step back, reexamine the reasons why the code is not getting accepted into the kernel, and ultimately improve it is what separates a real kernel developer from a donkey! Now move your ass, yes?
Tsunami -- You can't bring a good wave down!
Linus throws anecdotes. Gates throws money. Balmer throws chairs.
All comments are properties and trademarks of the voices in my head. Not like I'm gonna claim them.
Or having a cat who fubared your keyboard, so you're typing posts via ascii codes.
Your ad here. Ask me how!
... and Windows throws exceptions. So what else is new?
The higher the technology, the sharper that two-edged sword.
So, lets says you're running Word (not likely on linux, for quickest example I could come up with)
What the fuck.
After all, I am strangely colored.
For example, small talk is considered unnecessary or even rude in some situations. Getting to the point is a virtue in any conversation.
All these years I thought I was a social misfit, but apparently I'm just Finnish.
Boy will my parents be surprised.
R: That voice. Where have I heard that voice before? B: In about 365 other episodes. But I don't know who it is either.
Great, now instead of geeks pretending (or "self-diagnosing") Asperger's Syndrome to gain "geek cred", they'll learn Finnish. Just what we need, a bunch of Finnish-speaking introverts.
