Submission + - Nvidia loses huge order due to binary blob (phoronix.com)

David Gerard writes: "Phoronix reports: The Chinese, who also developed the Loongson MIPS CPU, were looking to order at least ten million graphics processors. The problem is that the GeForce/Quadro driver from NVIDIA is only available for Linux x86 and x86_64 architectures, not MIPS or even ARM (only the Tegra driver is for ARMv7). NVIDIA refused to release the source-code to their high-performance feature-complete cross-platform driver to the Chinese, and it would cost them millions of dollars to port the code-base, so they went to AMD for their GPU order."

Submission + - How satnav maps are made (pcpro.co.uk)

Barence writes: "PC Pro has a feature revealing how the world's biggest satnav firms create their maps. Nokia's Navteq, for example, has a huge database of almost 24 million miles of road across the globe. For each mile of road there are multiple data points, and for each of those positions, more than 280 road attributes.

The maps are generated from public data and driver feedback, not to mention its own fleet of cars with 360-degree cameras on the top.There’s an IMU (inertial measurement unit) for monitoring the pitch of the road, and the very latest in 3D surface-scanning technology too. This light detection and ranging (LIDAR) detector captures 1.3 million three-dimensional data points every second, mapping the world around Navteq’s field vehicles in true 3D.

The feature also investigates whether commercial mapping firms will be replaced by open-source maps."
