Microsoft to support 1394b standard

Microsoft Corp. will provide support for the IEEE1394b standard "within a reasonable time" after the launch of Windows Vista, according to a Microsoft Corp. representative who attended the IEEE1394 Trade Association meeting held here last week.

The Widows Vista is the software giant's flagship operating system, whose broad launch is expected in January, 2007.

Microsoft, which already supports IEEE1394a in Windows XP, will extend its support to the 800Mbit/s transfer rates in the IEEE1394b standard.

Although it won't be ready for Vista's initial release, Mark Slezak, program manager, Windows Device Experience Group at Microsoft, said support for 1394b would be available in a service pack, after the release of Windows Vista.

Asked if IEEE1394 might be losing its cachet on the PC market, Microsoft disagreed. Microsoft's support for 1394b is largely driven by its PC OEMs' demand, Slezak stressed. "They are asking a lot of questions about it, and it [1394b] is becoming a check-box item…There is no reason for us not to work with 1394."

The high-speed data transfer rate of 1394b will become crucial, according to Slezak, as the demand for external storage devices goes up. "It's important for high-bandwidth junkies," he said.

While anticipating the growing need for storing high-definition audio/video content in external storage devices, Microsoft is also interested in other potential applications of the 1394 standard, which range from machine vision to professional audio and video equipment, he explained.

For Microsoft to provide "in-box support" – in Vista – for 1394b, Microsoft wants to see further proliferation of the 1394b standard in even faster, specified data rates of 1.6-Gigabits per second and 3.2-Gigabits per second. Other items on Microsoft's wish list are a cheaper bill of materials and smaller pin for 1394b, Slezak added.

Microsoft took a seat in the 1394 Trade Association's board, and Slezak is a director of the board, along with representatives from Apple Computers, Texas Instruments, Samsung and others.

US says world safer, despite 11,000 attacks in '05

The U.S. war on terrorism has made the world safer, the State Department's counterterrorism chief said on Friday, despite more than 11,000 terrorist attacks worldwide last year that killed 14,600 people. The U.S. State Department said the numbers, listed in its annual Country Reports on Terrorism released on Friday, were based on a broader definition of terrorism and could not be compared to the 3,129 international attacks listed the previous year. But the new 2005 figures, which showed attacks in Iraq jumped and accounted for about a third of the world's total, may fuel criticism of the Bush administration's assertion that it is winning the fight against terrorism. Asked if the world was safer than the previous year, U.S. State Department Counterterrorism Coordinator Henry Crumpton told a news conference, "I think so. But I think that (if) you look at the ups and downs of this battle, it's going to take us a long time to win this. You can't measure this month ...

Al-Qaeda number two in new video

Al-Qaeda's number two Ayman al-Zawahiri has appeared in a video saying that Iraqi insurgents have "broken the back" of the US military. He praised "martyrdom operations" carried out by al-Qaeda in Iraq in the video, posted on an Islamist website. And he called on the people and army of Pakistan to fight against President Musharraf's administration. This is the third message from prominent al-Qaeda leaders to emerge within a week. A tape from Osama Bin Laden was broadcast on 23 April, followed two days later by a message from Iraqi insurgent Abu Musab al-Zarqawi. Pakistan focus Zawahiri, who wore a black turban and a white robe in the video, described the leaders of Egypt, Jordan, Saudi Arabia and Iraq as traitors, and urged Muslims to "confront them". He praised Iraqi militants, saying that the US, Britain and allies had "achieved nothing but losses, disasters and misfortunes" in Iraq. "Al-Qaeda in Iraq alone has carried out 800 ma...

Does light have mass?

The short answer is "no", but it is a qualified "no" because there are odd ways of interpreting the question which could justify the answer "yes". Light is composed of photons so we could ask if the photon has mass. The answer is then definitely "no": The photon is a massless particle. According to theory it has energy and momentum but no mass and this is confirmed by experiment to within strict limits. Even before it was known that light is composed of photons it was known that light carries momentum and will exert a pressure on a surface. This is not evidence that it has mass since momentum can exist without mass. [ For details see the Physics FAQ article What is the mass of the photon? ]. Sometimes people like to say that the photon does have mass because a photon has energy E = hf where h is Planck's constant and f is the frequency of the photon. Energy, they say, is equivalent to mass according to Einstein's famous formula E = m...
