Apple's Macworld Looking To Corporate Users 287

Posted by Zonk on Friday January 05, 2007 @02:00PM from the hi-i'm-a-business-mac dept.

coondoggie writes to mention a Network World article about a focus on corporate users at the upcoming MacWorld Expo. Along with the consumer announcements (iTV, iPod stuff), there will be several elements dedicated to introducing IT pros to Apple hardware. From the article: "The show has really evolved. For a long time it was a consumer-oriented show and those of us who are from the enterprise space - there weren't very many of us - would use it as a place to meet and compare notes ... Now Macintosh in the enterprise is becoming more recognized and there are tracks that are specifically for us enterprise people. We don't have to sneak off anymore."

Comment Another example of Driver-Loaded Firmware: M-Audio (Score 3, Insightful) 229

by azzurro on Monday January 01, 2007 @03:57PM (#17424062) Attached to: The Problem With Driver-Loaded Firmware

M-Audio audio interfaces also use driver-loaded firmware.

From http://www.theory.physics.ubc.ca/transit.html:

This card [M-Audio Transit] needs to have firmware downloaded to the card on the USB bus to work. It uses a non-standard "DFU" method which seems to have some problems with Linux. It also mixes its Type I and Type III endpoints to confuse the software. I have found (with the help of and software written by Clement Ladisch and Takashi Iwai.) a way to make this card useable.

The card requires firmware to be downloaded to the card first for it to work as a soundcard. While it appears on the usb bus with Vendor/ProductID of 0763/2806 this is a very primative usb device that does nothing except wait for firmware.

A firmware loader for M-Audio audio devices is available at http://usb-midi-fw.sourceforge.net/. Interestingly enough, the set-up procedure involves copying the firmware bin file from the Windows driver installation, which is subsequently used by the firmware loader.

Anyways, TFA makes some interesting points:

Unrestricted redistribution of firmware files is satisfactory for some open source operating system projects like OpenBSD, FreeBSD, and many varieties of GNU/Linux, but others like Fedora Core and Debian demand an entirely free software environment, so redistribution of the firmware without the ability to modify and distribute the source code is prohibited.

The firmware, although its being loaded to the device, is still firmware. Do distributions that demand an entirely free sofware environment ship drivers for devices with proprietary firmware? Of course they do. I'm not convinced that this should be any different.

I think that Theo de Raadt, of OpenBSD, has it right:

So instead of lobbying for documentation to write open source firmware, de Raadt would prefer to simply have the right to freely distribute necessary proprietary firmware files with his operating system, along with correct firmware interface documentation so that a driver can be created, and information from the manufacturer regarding bug workarounds.

Nanoknives To Be Used to Cut Cells 78

Posted by Zonk on Sunday November 26, 2006 @07:44PM from the take-that-you-cytoplasmic-scoundrel dept.

Roland Piquepaille writes "American researchers have built a carbon nanotube knife. According to the National Institute of Standards and Technology (NIST), this nanoknife will be used to cut and study cells. With this new tool, scientists and biologists will be able to make 3D images of cells and tissues for electron tomography, which requires samples less than 300 nanometers thick. And as cells are usually stored in wax for dissection, the researchers plan to test their nanoknives on a block of wax later this year. But read more for additional references and a picture of this nanoknife."

UK Schools Bans WiFi Due To Health Concerns 535

Posted by Zonk on Friday November 24, 2006 @09:39PM from the no-bad-teeth-jokes dept.

Mantrid42 writes "Schools in the UK are getting rid of their WiFi network, citing health concerns from parents and teachers. The wireless emanations, parents fear, may be the root cause of a host of problems from simple fatigue to the possibility of cancer. A few scientists think younger humans may be more vulnerable to the transmissions, because of thinner skulls. From the article: "Vivienne Baron, who is bringing up Sebastian, her ten-year-old grandson, said: 'I did not want Sebastian exposed to a wireless computer network at school. No real evidence has been produced to prove that this new technology is safe in the long term. Until it is, I think we should take a precautionary approach and use cabled systems.'"

Wii Confirmed at 480p 223

Posted by Zonk on Thursday November 02, 2006 @01:38PM from the good-but-not-that-good dept.

Eurogamer is reconfirming that the Wii only outputs at 480p, after the official Nintendo magazine mistakenly said otherwise. From the article: "Nintendo UK also recently said that it had every intention of releasing peripherals like the component cable — used to achieve the 480p resolution — at retail, despite suggestions that you'd have to buy the cables through online shops in the US. The interest in Wii's high-resolution options is of course spurred on by Microsoft and Sony's battling over the higher end. Both PlayStation 3 and Xbox 360 generally offer games in 720p, with 1080p now possible for developers who want to go the extra mile (well, the extra 1,152,000 pixels, anyway)."

If Not America, Then Where? 2349

Posted by Cliff on Wednesday October 25, 2006 @01:45AM from the a-new-home-for-the-free-and-brave dept.

Wellington Grey asks: "Often during our heated political discussions on slashdot, several people will mention their desire to leave the country. As an American living in England, which sees much the same problems as the US, I often wonder where these Americans would go. So, I pose two questions for the restless: 1) Where would you live, if not in America and 2) What's stopping you from going?"

AppleBerry Predicted? 181

Posted by Hemos on Monday June 05, 2006 @11:44AM from the the-fruits-get-together dept.

dr_fatty writes "The Globe and Mail is reporting that analyst Peter Misek, who predicted a partnership between Research in Motion and IBM, is now predicting a partnership between Apple and Rim. The predicted result? The AppleBerry. 'Such a deal would have huge merit because each company lacks what the other provides. RIM wants a firm foothold in the consumer market and Apple doesn't have a presence in the booming wireless data sector, he said.'"

High performance FFT on GPUs 274

Posted by Hemos on Monday May 29, 2006 @12:30PM from the testing-it-out dept.

A reader writes: "The UNC GAMMA group has recently released a high performance FFT library which can handle large 1-D FFTs. According to their webpage, the FFT library is able to achieve 4x higher computational performance on a $500 NVIDIA 7900 GPU than optimized Intel Math Kernel FFT routines running on high-end Intel and AMD CPUs costing $1500-$2000. The library is supported for both Linux and Windows platforms and is tested to work on many programmable GPUs. There is also a link to download the library freely for non-commerical use."
