Netflix on the Nintendo 3DS: hands-on | This is my next... The wait is over: Nintendo today announced that it's finally bringing Netflix to the 3DS via a free app, available for download in the eShop right now. This means that US citizens and Canadians alike can now watch Shutter Island for the 30th time wherever Wi-Fi is available. As you'd expect, the content displays in 2D on the top screen and the familiar two-axis menu UI rests in the bottom screen. Wondering about 3D content? As soon as I began tinkering with the 3DS Netflix app, I immediately noticed how simple and clean it is. Video quality is what you'd expect from an 800 x 240 screen -- it's okay, but we prefer something more crisp and less washed out. Source: Nintendo PR

OnLive founder wants to revolutionize wireless with DIDO technology | This is my next... You may know Steve Perlman as the man behind OnLive, but it's looking increasingly foolish to think the California entrepreneur is all about games these days. WebTV may be a thing of the past, but Perlman's company Mova provides advanced facial capture software to big names in Hollywood, and on June 4th, he told students at Columbia University that his incubator Rearden had developed a groundbreaking new approach to wireless technology. That last one's quite the claim, and details were scarce in June, but today the company's ready to explain how it will "completely transform the world of communications" with a little something called DIDO. DIDO stands for Distributed Input Distributed Output, and there's a reason that word "distributed" is repeated twice -- basically, what Perlman is imagining is peer-to-peer, ubiquitous Wi-Fi.

Introduction to Matrices / Matrix Size Introduction to Matrices / Matrix Size (page 1 of 3) Sections: Augmented & coefficient matrices / Matrix size, Matrix notation & types, Matrix equality This lesson is not yet availablein Purplemath Plus. Augmented matrices Matrices are incredibly useful things that crop up in many different applied areas. Matrices were initially based on systems of linear equations. Given the following system of equations, write the associated augmented matrix. 2x + 3y – z = 6–x – y – z = 9x + y + 6z = 0 Write down the coefficients and the answer values, including all "minus" signs. That is, given a system of (linear) equations, you can relate to it the matrix (the grid of numbers inside the brackets) which contains only the coefficients of the linear system. The entries of (that is, the values in) the matrix correspond to the x-, y- and z-values in the original system, as long as the original system is arranged properly in the first place. x + y = 0 y + z = 3 z – x = 2 I first need to rearrange the system as:
