Submission + - Red Hat Nears $1 Billion, Closing Door on Clones->

darthcamaro writes: Red Hat almost at its goal of being the first pure play open source vendor to hit $1 Billion in Revenues. Red Hat reported its fiscal 2011 revenues this week which hit $909 million. Going forward Red Hat has already taken steps to protect its business by changing the way it packages the Red Hat Enterprise Linux 6 kernel, making it harder for Oracle to clone.

"We are the top commercial contributor to most of the components of the Linux kernel and we think we have a lot of value and we want to make sure that, that value is recognized," Red Hat CEO Jim Whitehurst said. "In terms of competition, I don't think we necessarily saw anything different from before but I'd say better to close the barn door before the horses leave than afterwards."

Submission + - The Solid State PC->

Sivar writes: " built 'a truly solid-state PC'.
A silent PC is one that makes absolutely no noise, and by necessity has no moving parts (including fans). Such systems usually use very low-end hardware limited to trivial tasks such as running a cash register. The system introduced today, a Solid-State PC (SSPC) is a powerful quad-core Windows 7 system which runs most software faster than the majority of modern PCs, yet uses less than 25W idle."

Submission + - Stock trades to exploit speed of light->

SpuriousLogic writes: Financial institutions may soon change what they trade or where they do their trading because of the speed of light.

"High-frequency trading" carried out by computers often depends on differing prices of a financial instrument in two geographically-separated markets.

Exactly how far the signals have to go can make a difference in such trades.

Alexander Wissner-Gross told the American Physical Society meeting that financial institutions are looking at ways to exploit the light-speed trick.

Dr Wissner-Gross, of Harvard University, said that the latencies — essentially, the time delay for a signal to wing its way from one global financial centre to another — advantaged some locations for some trades and different locations for others.

There is a vast market for ever-faster fibre-optic cables to try to physically "get there faster" but Dr Wissner-Gross said that the purely technological approach to gaining an advantage was reaching a limit.

Trades now travel at nearly 90% of the ultimate speed limit set by physics, the speed of light in the cables.

Comment Show the CLI controlling the GUI (Score 5, Interesting) 467

Many GUI applications can be controlled via GUI commands. Showing this helps students understand the link between the magic that goes on under the hood, and the actual action that takes place to make that happen.
Sure, not everything is a GUI shell over a CLI program, but the concept of typing a command isn't that different from one of making an API call to Qt or GTK+.

That's funny, I was just in several of the buildings in Redmond last week and found that all drinks -- even those in the cafeteria, are gratis. Paying isn't even an option -- there's simply nowhere to put the change.

For any personal issues you may find with Microsoft as a company, I have seen and heard nothing but good things from their employees.

Comment It works for printers (Score 2, Insightful) 511

Digital images are displayed in RGB, yes.

But colors are printed in CMYK (Cyan Magenta Yellow Black), and you'll notice that the best photo inkjet printers have more than just those four color cartridges. They often have the four plus "photo cyan", "photo magenta", etc. and it does make a huge difference.

As you know, some colors cannot be accurately expressed in CMYK, nor can some in RGB (even though theoretically any color is possible, but theory is not reality in this case).

While the extra color may or may not make a big difference, there is at least precedent indicating that the idea is sound.

Comment Block only obnoxious ads (Score 1) 1051

Ad-block has a rather heavy handed policy of blocking every ad it possibly can, at least with the most common lists.
My proposed solution: Add a voting system, or some other means to detect when ads are very intrusive (like the flashing "You've Won!!!!" ads), and keep a list of ads or ad servers that follow that criteria.

Then, users can subscribe to an "obnoxious ad" list in adblock, eliminating the ones we all hate (discouraging their use at all), and allowing those which aren't bad, or are actually useful.

Submission + - Why BitTorrent causes latency and how to fix it

Sivar writes: ""Anyone VoIP or online gamer who has a roommate or a family member who uses BitTorrent (or any P2P application) knows what a nightmare it is when BitTorrent is in use. The ping (round trip latency) goes through the roof and it stays there making VoIP packets drop out and game play impossible." George Ou looks into why BitTorrent seems to affect performance so much more than other types of file transfer and a controversial way to fix it."

CoreCodec Apologizes For CoreAVC Takedown 185

I Don't Believe in Imaginary Property writes "In a follow-up to the previous story, CoreCodec has apologized for the incorrect DMCA Takedown notice that took the CoreAVC project offline. There's also a public statement by co-founder Dan Marlin saying in part, 'I'd like to publicly apologize to Alan [CoreAVC project lead] for the disconnect between him and us as well as the disruption to the project as there was no ill will intended and we were already working on a resolution with him before this went public.' They've also created a new policy for sending out DMCA Takedown notices, so that they won't misuse them in the future."
