Helicopters make a lot of noise because of a physical phenomenon called blade-vortex interaction. Eurocopter engineers have developed a new kind of rotor blade that attenuates this problem. It's called Blue Edge, and—as you can hear—it works beautifully:

The new blade shape is combined with another technology called Blue Pulse, which adds three flaps to the edge of the rotor blades. These flaps move up and down at 15 to 40 times per second, using piezoelectric motors that also help to reduce the blade-vortex interaction. [Autopia]

The New York Times is saying that Walmart will acquire Vudu, the online movie service. The report’s consistent with earlier rumors, and may just be a match made in heaven. UPDATE: Walmart’s confirmed the acquisition; press release below.

Walmart sells more DVDs than just about anybody on the planet, but have so far been shut out of the increasingly popular movie streaming business that’s buoyed Netflix recently. Vudu gives them a convenient way into that market without having to build from the ground up.

For Vudu, selling out couldn’t come at a better time: they’ve never been profitable, although they’ve been gaining some traction by having their players embedded in increasing numbers of TVs. Being owned by the world’s largest retailer will help them build on that momentum. It also gives consumer electronics makers even more incentive to preload their sets with Vudu, since Walmart will be more inclined to sell products that incorporate a property that it owns.

But what about for consumers? Actually, it could end up being a win there, too. Nobody’s more effective at driving down prices than the big box retailer, and giving Vudu more visibility and market share should lead to some healthy price competition.

Time will tell, but the could be one business transaction that ends up making sense for just about everyone.

Walmart Announces Acquisition of Digital Entertainment Provider, VUDU

Company takes next step to enhance home entertainment and information delivery options for consumers

BENTONVILLE, Ark., Feb. 22, 2010 — Walmart announced today a definitive agreement to acquire VUDU, Inc., a leading provider of digital technologies and services that enable the delivery of entertainment content directly to broadband high-definition TVs and Blu-ray players. The deal is expected to close within the next few weeks.

VUDU is a revolutionary service, built into a growing number of broadband-ready TVs and Blu-ray players, that delivers instant access to thousands of movies and TV shows directly through the television. Customers with broadband Internet access and an Internet-ready TV or Blu-ray player can rent or purchase movies, typically in high-definition, without needing a connected computer or cable/satellite service. New movies and features will be added continually, enabling customers to enjoy a product that continues to become more robust long after they have left the store.

“The real winner here is the customer,” said Eduardo Castro-Wright, vice chairman for Walmart. “Combining VUDU’s unique digital technology and service with Walmart’s retail expertise and scale will provide customers with unprecedented access to home entertainment options as they migrate to a digital environment.”

VUDU has licensing agreements with almost every major movie studio and dozens of independent and international distributors to offer approximately 16,000 movies, including the largest 1080p library of video on-demand movies available anywhere. Via their broadband Internet connection, users have the ability to rent or buy titles and begin viewing them instantly.

VUDU will continue developing entertainment and information delivery solutions such as VUDU Apps, a platform that delivers hundreds of streaming Internet applications and services to TVs and Blu-ray players with built-in Internet connectivity. VUDU has partnered with some of the leading names in Internet and media entertainment to offer applications on its platform including Facebook, Flickr, Twitter, The New York Times and The Associated Press.

“We are excited about the opportunity to take our company’s vision to the next level,” said Edward Lichty, VUDU executive vice president. “VUDU’s services and Apps platform will give Walmart a powerful new vehicle to offer customers the content they want in a way that expands the frontier of quality, value and convenience.”

VUDU, based in Santa Clara, Calif., will become a wholly-owned subsidiary of Walmart. The company is not disclosing financial terms of the agreement as the acquisition is not material to its first quarter earnings for fiscal year 2011.

Ever wish you could achieve a documentary-style face blur in your video projects? DIY video blogger extraordinaire Tinkernut details how to do exactly that with a handful of free software.

The star application in this process is a free app called Wax, which handles video compositing and some special effects. Tinkernut’s excellent walkthrough covers every step in the process.

Apart from blurring the face, the video also covers how to change the voice to give it a little extra anonymity, but be aware: At the very least the voice adjustment is just a pitch change, so it could be reverse engineered easily enough by someone determined to hear the voice. The same may be true for the blur, but we're not exactly video modulation experts over here. Either way, this isn't a "hide from the KGB" guide—it's just a simple and effective method for blurring out faces or other sections of your video.

I thought this Ballmer’s autograph on a Macbook Pro was fake, but according to this video of the big man scribbling it, it’s not. Somewhere in a dark place, Jon Ive is bracing himself and sobbing. With a British accent.
