Feds uphold jailbreaking laws on DVDs, game consoles, tablets

The U.S. Copyright Office published its new set of rules on whether people can jailbreak smartphones, tablets, and gaming consoles today; it also outlined the guidelines on DVD copying.

Overwhelmingly, its conclusions were that besides smartphones, all of the above remain illegal.

Every three years the Copyright Office takes requests from digital rights proponents and opponents to re-examine the laws under the Digital Millennium Copyright Act that dictate whether people can unlock or jailbreak their varied devices. Today, in a lengthy document (PDF), the government listed all of the changes it made.

The key developments are that people cannot … Read more

Unlocked fin likely brought down X-51A in August crash

The U.S. Air Force said today that an experimental test in August of its hypersonic X-51A Waverider failed due to a fin inadvertently unlocking and sending the aircraft into a corkscrew that ended in a crash into the Pacific Ocean.

At the time, the Air Force said only that the August flight had ended with the crash, but didn't reveal what had been at fault. But in a conference call today, X-51A program manager Charlie Brink explained what he and his colleagues have learned over a couple of months of investigation.

The August flight was the third of … Read more

Low-price Huawei Ascend Y joins U.S. Cellular (hands-on)

Today, Huawei and U.S. Cellular announced the Huawei Ascend Y, a budget Android smartphone for first-timers. A few weeks ago, I got to briefly handle the Muve Music device.

With its Android 2.3 Gingerbread OS, the Ascend Y certainly isn't angling for tech-savvy users, or those ready to invest in a higher-cost handset. Its 3.5-inch touch screen definitely felt small compared with today's larger-screen phones, but its HVGA (480x320-pixel) resolution is appropriate for the display and looked fine. The Swype virtual keyboard will help compose text in tight spaces.

I didn't get an opportunity … Read more

Huawei offers Australia 'unrestricted' access to hardware, source code

Huawei has offered to give the Australian government "unrestricted" access to the firm's software source code and hardware equipment in an effort to dispel security fears, months after the Chinese telecoms giant was barred from supplying infrastructure equipment for the country's national broadband network.

The Australian government barred Huawei from bidding on contracts for the network earlier this year, saying it had a "a responsibility to do our utmost to protect [the network's] integrity and that of the information carried on it".

John Lord, Huawei's Australian chairman, said on Thursday that the … Read more

Lenovo: Making it in the U.S.A. (Q&A)

China's premier PC company, Lenovo, is moving some of its desktop, laptop, and tablet production to the U.S. I asked the company -- which Gartner says is now the largest PC maker on the planet -- to explain what making a product in the U.S. means exactly.

I spoke with Mark Stanton, director of global supply chain communications at Lenovo, about the company's plan to to make computing devices in North Carolina, including its ThinkPad Tablet 2 and ThinkPad laptops.

Q: What does "made in the U.S." mean in this case? Stanton: The … Read more

Boeing trucks ahead with 8-wheeling laser weapon

The promise of laser weapons is that they will dispatch enemy missiles and other threats at the speed of light. Progress on those weapons systems, however, sure has been a heck of a lot slower.

When last we heard from Boeing about the HEL TD (High Energy Laser Technology Demonstrator) program in June 2011, the defense contractor had just finished system integration of key components, including the installation of the beam control system and other hardware on the 8-wheeled, 500-horsepower Oshkosh HEMTT (Heavy Expanded Mobility Tactical Truck).

This week, Boeing said that it's now engaged in the next phase … Read more

An awesome-sounding headphone amplifier Kickstarter project

It was just a few weeks ago when my buddy Tyll Hertsens was raving about Colin Shaw's Sicphones amplifier Kickstarter project. Hertsens never steers me wrong, so I contacted Shaw, and a few days later I received the amp. Hertsens was right. This design uses a newly available SemiSouth silicon carbide transistor, and the amp sounds amazing. If Shaw makes his Kickstarter goal he'll be able to sell amp kits for as little as $229, and assembled amps for $279! DIY-ers can spring for just $35 and get the Sicphones amplifier PC board, assembly instructions, and parts source … Read more

Apple v. Samsung: Why is Judge Koh so angry?

Lucy Koh is chewing someone out again.

Anyone following the Apple v. Samsung patent trial has noticed the frequency with which Koh, the U.S. district judge presiding over the case, has scolded lawyers from both sides.

The most vivid example came last week, when Apple lawyers notified Koh that they wished to cram a large number of witnesses into the remaining few hours they had to make their arguments. This would have added to the mountain of paperwork and generated more work for Koh and her staff.

"Come on," Koh told Bill Lee, one of Apple's … Read more
