God damn do I hope nobody distributes a build of this for ubuntards to use!
Con's original scheduler had no chance of becoming the vanilla scheduler, as it was in no way general purpose, had a number of regressions, and he was a dick about the whole thing (in a community of assholes!). He was also insistent on making the scheduler modular, something that Linus and his lieutenants rightly refused outright. This new scheduler seems to amplify all the bad qualities of his last one.
Something I found quite distasteful in the CFS battle was the way he gathered a noisy following of clueless newbies/tweakers using his kernel that made it very hard to have any honest discussion of the matter. Repeating that again with a much larger and more adolescent crowd of Ubuntu users would be really annoying.
Hey, I use Ubuntu for my desktop at work, and in the past have done substantial deployments of it to managed end-user desktops. It's not beneath me or anything.
I'm sneering at a particular subset of Ubuntu users -- the entire userbase of ubuntuforums.org, the Digg/Reddit/Lifehacker "top ten ways to..." readers. They are the "Power Users" of desktop Linux -- they have no clue how anything works nor the facility to learn, but they sure are earnest and they love to evangelize! They'll seize any opportunity to apply their cargo-cult knowledge to help you with the problems they think you have.
In past generations these people (largely adolescents) would have been know-nothing partisan tweakers of Windows, Classic Mac OS, BeOS, Amiga, or any number of 8-bit home computer platforms. For now Linux is the cool thing to wank over -- compiz helped a lot with that. A couple years ago it looked like a lot of them were defecting to the Hackintosh community -- does anyone know if that trend held up numbers-wise?
Why are you calling these people "Ubuntards"? I don't know about Digg or Lifehacker but the vast majority of Linux people on Reddit despise Ubuntu and use Arch instead.
I know that http://www.reddit.com/user/dons is constantly evangelizing Haskell and Arch on reddit, to the point where he's self-parodying. He's also single-handedly responsible for there being 1314 (!) haskell packages in Arch.
At least Arch gives the tweakers a bit more rope with which to form either a noose or a lasso.
Could you explain? I can't evaluate the technical merits, but is there an alternative if you actually want a scheduler to cater to a desktop user's needs?
I am on the fence about whether this is a good troll or a bad troll. It certainly exploits the "someone on the internet is WRONG" ethos of HN, but I don't think it does so in a particularly amusing way. I'm going to say that it's a rather boring troll.
(I do find myself compelled to say that the mathematical convention is that an infinite sum is defined to be equal to the limit of the partial sums, if it exists.)
Considering when you created your account, and the subject of your post, "troll" seemed like the most likely explanation. Sorry about that. (It's sort of a typical troll to make a technically incorrect statement and then watch people get all agitated as they correct you. In fact, it's one of my favorite trolls, right behind making a sarcastic statement which you know will be taken literally by half of the audience, a la "A Modest Proposal".)
Anyways, assuming that your comment was in earnest, the arrow is typically used for functions (or sequences). E.g.,
1/n -> 0 as n->infinity
You could write:
1/4 + 1/16 + ... + 1/4^n -> 1/3
But you would write
1/4 + 1/16 + ... = 1/3
You wouldn't write (or at least I've never seen it)
1/4 + 1/16 + ... -> 1/3
It's not really a mathematical issue, just a definitional one: the left hand side is considered a real number, not a sequence of real numbers (or function :N->R, or whatever).
Yes, it is 1/3. Given a series of partial sums (which in turn form an infinite sequence), then if the infinite sequence converges to some number B, the infinite sum likewise converges to the same number B.
It's exactly like saying lim as x -> 1 of 2x -> 2. You don't write it that way. You write it as lim as x -> 1 of 2x = 2.
