“The MIT researchers found that the separate cores were spending so much time ratcheting the [memory] counter up and down that they weren’t getting nearly enough work done,” the report states. However, the researchers also found that “slightly rewriting the Linux code so that each core kept a local count, which was only occasionally synchronized with those of the other cores, greatly improved the system’s overall performance.”
Come on! Ubuntu has worse drivers and compatibility against Windows?
The fact that iTunes is not compatible with Linux it's clearly not Ubuntu's fault. Apple has no interest in making it compatible with Wine or porting natively to Linux.
I doubt Windows has out-of-the-box drivers for everything like printers, usb, video, audio, chipset, raid, wifi (+broadcom!!), ethernet and even 3G devices without downloading drivers from different sites, installing and rebooting the SO!
Again, this comparison is just flawed or even FUDed...
Interesting if you compare to a democratic government and the critical decisions they make without any popular consensus...The people voted for that government and many time, their decision aren't orthogonal to people's desire, and unlike opensource,if you don't like it you can emigrate to other country. Yep..this is really hard to accomplish unlike opensource since you can fork the country and govern it the way you want or even you can change to another country or in opensource terms, to another project.
The Ubuntu governors are taking some critical(design) decisions based on their know-how expecting the hole community to adopt it as a good decision.
Is not about whinning by anti-M$ goons. It's about anti-FOSS goons whinning we are tired of.
And yes, we have the cojones (b@lls) to compete with M$: Firefox, Linux, OpenGL, Java, Qt are these no competitors to M$ counterparts?
Face that, opensource is here to stay and eclipse closed-source solutions. Start learning good standards instead of clicking next/back/voila buttons...
From the site:
"Flash memory is a wonderful invention. It can randomly access data at speeds up to 60 times faster than a hard disk. Similarly, the newest MLC models are as cheap as enterprise hard disks. But Flash has a problem: when this data needs to be written back, the random write speed is often only 1/500th of the random read speed. As a result, most flash drives inherently perform a little better than some hard drives, and a little worse than others.
Our patent pending Managed Flash Technology (MFT) solves that random write problem, enabling Flash Drives to write clusters of random data in linear streams, thus allowing it to write at the full Flash Drive linear write speed of forty to ninety megabytes a second (which is 10,000 to 22,000 4kb writes per second).
Normal random writes put things back where they came from. Writing linearly requires us to put them where ever free space is available at this moment. This method of remembering things works as long as a memory table exists to tell you where a logical sector is at this moment.
Similarly, MFT often extends the effective write-life of Flash SSDs by two orders of magnitude. While this may not be of practical benefit if you are using an expensive single-level cell (SLC) based Flash SSD, it may be absolutely critical if you want to use the vastly less expensive, but more limited erase-life multi-level cell (MLC) drives.
That is the essence of MFT. In the following pages, we will consider particular elements in detail."
You could use Managed Flash Technology to improve write performance and drive lifetime as well (Windows and Linux). For MLC or SLC drives.

Yet, worse. From TFA:

Stop FUD'ing please.

Well, at least the 'kuh' thing can be translated to ass in Portuguese ;)
Why not just use Qt instead? It's LGPL....why people still using GTK?

My iJam also bricked. Damn! http://www.youtube.com/watch?v=HqqqVYKoGiw
Anything like this (Scalable Nonblocking Data Structures) but on C/C++?
It woul be interesting anyone posting any java regular expression for detecting XSS attacks XD Tnx!
