Linux is pretty terrible for performance multi-threading, that's a fact. It features unreliable file IO too, but I digress..
In the case of Facebook, it's true that it's not the OS fault since Mutexes are always slow anyway.
There are lockless libraries that lock the CPU(s) for one cycle so that the program doesn't need to lock a mutex to increment a counter, for example. Thousands of times faster...
But these wouldn't have helped there. Like you said, it just seems like a design problem in the software. Still 140M users is very impressive.
Will it fix the most notorious Linux bug??

Fedora 10 Released

· Score: -1, Troll
There is been a bug in the Linux kernel that makes computers reboot every 47.9 days. This bug has been around for nearly 15 years!
I don't think that Linux can claim to be ready for the desktop (nor the server for that matter) until its development process is streamlined. As it is, the development priorities are set at the whims of one person.
It's really too bad that Linux follows an open source model that is unable to make the operating system self-sustainable. Basement development can only go so far, it seems. To go beyond that, Linux must rely on the good will of sucker millionaires.
Once in a while, someone turns a buck by using the old take but don't give back approach.
Linux is nice but I recommend keeping it far away from any bank account. It's a black hole for money...
I find it strange that Linus uses Windows Media Center instead of MythTV...
But I guess that is to be expected as he is known to be a pragmatic person (see Linux GPL v3 debacle).

There are no legal reasons. 6 months after sending notices Linux can be GPL3, no problem.
His ideological reasons are that he wants to see Linux running on everything possible, including network amd multimedia appliances. So long as the distribution is wide, he doesn't care about the "sharing" aspect of it. After all, the work is all done by suckers anyway.
Open source or closed source is immaterial to the final result. Especially when the desired result is wrong to begin with.
Those builders only seek more kitchen sinks to throw into that bloatware known as the Linux Kernel. As an intense user of Linux, Windows 2000 and Vista (and XP before), I can say without a doubt that Linux is the least stable modern OS that I know. I'll give Linux this: it's more stable than Windows 95.
But I digress. Linux should be flushed down the toilet and replaced with a macrokernel architecture. Those open source drivers that the builders want to throw inside the kernel will only help make Linux even less flexible. Proof? Linux has been stuck on the 2.6 branch for years because it's an unwieldy blob.
Terrible security: who knows where the software is from. Legal concerns: Lots of stolen code. Bad quality: geeks don't like to finish what they do, just do the "fun" parts. No testing: geeks don't like to test. Laughable documentation: geeks don't like to communicate with users. Expensive: Hooked on the initial $0 price, customers get shafted on support. No help: Open source support, especially paying one, rarely brings solutions.
And on a global scale, damage to the economy, reduction of research and knowledge production, moving of capital to foreign (and potentially ennemy) countries, providing technological material support to terrorist groups.
Open source? It's bad..
It might be good if the laws were better. For instance, more patents, and more prison time for violators.
There are plenty of problems with Linux as it is right now. Next thing we'd know, someone would bring the OS2 scheduler into Linux under Linus' nose... That's not really needed right now, with all the current instability issues...
One of the reasons why Linux is so easy to hack and root is that it is difficult to configure. Howto's and examples tend to be just not good or complete enough.
This is likely because being a hobbyist's project, Linux developers do what they love: develop. In the meantime, documentation and configuration tools don't get done since they are boring. Users who are not inside the ivory tower are left out in the cold.
Miguel is an open source Hero. Things are possible on Linux, and other UNIXes, that would never have been without first his strong-held beliefs in interoperability with wide spread standards, and second his unrelented efforts in building on those beliefs.
I am talking about Mono here, of course. So, if he says that OOXML is good, than you can believe it.
In the end, Linux on the desktop will only happen through Microsoft.
Regardless of what the users do, we should be seeing better security all around based on 2 trends:
1- Rise in Windows Vista use 2- Decrease to near 0 in the number of Linux home computers as the idea of Linux on the Desktop continues to unravel.
I think that the years of spambots and so on are becoming numbered. And that's not even mentioning Microsoft's efforts in the field of email authentication and security:)
Some would argue that just booting Linux causes copyright and patent violations. They are so big and so common that they become difficult to distinguish.
I don't remember if the summary mentions the death penalty or not, but I think this could be a big issue concerning it.
It would be better if most convicted criminals were executed. Other than improving the living conditions of the others, wrongly convicted people wouldn't have to suffer an eternity in jail for no reason. And if people are somehow recognized as innocent later on, then they can be declared martyred with an appropriate epitaph. This way they are rehabilitated into society without much fuss.
And for the rigthfully convicted.. good for them anyway.
I find that the slashdot's new discussion system, probably invented to deal with trolling, negatively impacts the discussion of educated opinions. For instance, Comcast versus IP thieves.
It must be difficult for a forum operator to draw the line between security and freedom. Cmdrtaco must understand George W. Bush better than anyone else here.
Do you use SUSE? If so, when the shoe doesn't fit, you don't have to force it. But everytime someone downloads RedHat (for example), someone in India has to skip a meal... And that's why Tux is so fat, BTW.
There's no Robin Hood here. Downloaders hurt people: law abiding customers who have there own products degraded by the action of a few, and obviously, all the people who have the rug stolen from under their feet (the artists amongst others).
I think that Comcast is acting in good faith here and in the interests of its best customers.
All the electricity spent on that waste of time could have been used towards not producing global warming.
As always, the inferior leftist cabal of democrats and Linux thieves, riffe with conspiracy theories, are themselves the cause of all the problems on the planet. I could use their nostrils for air filters on my car's exhaust system.
Before sending an OLPC to Africa, I'm gonna send a crate of guns.
While America is blessed with great natural resources, so is Africa. And let us assume that racial differences between the populations don't account for much.
Why are we so superior to Africans in just about every way? Easy, we organized ourselves properly. Maybe there are plenty of Americans who are lazy, probably the same percentage as Africans BTW -- not more, but even these lazy people stand up for values that matter. Even Democrats. although to a lesser extent.

Open source projects are not run professionally. I don't recommend getting involved with them as a career move.
How about joining the Microsoft campus instead? Learn about the full software engineering cycle. Now, that would be something!

Its development process makes Linux inherently insecure.
ext-3 is known to have serious issues with very large partitions due to its implementation of journaling...
I recommend Windows Vista 64-bit + NTFS for your large storage needs.

Linux is full of bugs, and it's about time that people on here start realizing it. Any application that performs a simple strcpy brings linux down.

1 - Unlocking is stealing from the service provider who is footing half the bill for the phone.

2 - Linux open sourcers are code thieves.

3 - Is this an attempt by Apple to woo Linux developers into the BSD camp by saying it's OK to steal? Looks like it to me!

Taken from my own signature: "Linux violates 235 Microsoft patents."
One way or another, P2P is almost always stealing. Especially when it's Linux ISOs!!!
P2P = stealing
