Raspberry Pi's new turbo mode boosts performance by roughly 50 percent, doesn't void warranties
Giving a Raspberry Pi extra voltage is a quick way to squeeze out additional processing power and void its warranty, but the folks behind the tinker-friendly board have devised a turbo mode that boosts performance by roughly 50 percent while keeping warranties intact. After studying the effects of temperature and voltage on the hardware's lifespan, the team found that dynamic overclocking and overvolting doesn't affect the Pi's health appreciably. As a result, speeds can be pushed from 700MHz to 1GHz only when additional horsepower is needed, and things are reined back in when the CPU grazes 185 degrees Fahrenheit (85 degrees Celsius). Benchmarks show the extra computing oomph makes the Pi 52 percent faster on integer, 64 percent speedier on floating point and 55 percent snappier on memory tasks. The new mode is available in the latest firmware update, which also includes temperature and frequency widgets, better analog audio, improved USB performance and support for WiFi dongles out of the box.

$49 Cubieboard for developers is heavy on specs, light on the wallet
You've already got plenty of options if you're in the market for a developer board, but it might be worth taking a look at the new $49 Cubieboard, which packs quite the specs given its price point. The board hosts a 1GHz AllWinner A10 Cortex A8 CPU with Mali-400 GPU, 1GB of RAM and 4 gigs of onboard storage. For ins and outs, you're looking at 1080p HDMI, Ethernet, one MultiMediaCard (MMC) slot, a SATA port, two USB hosts, an IR sensor and 96 extender pins for solder junkies. Cubieboard's Wiki page lists an additional MMC slot and USB OTG, but as this doesn't check out in the pictures, we assume they've either been scrapped, or they'll be added on for later production runs. As you would expect, several versions of Linux and Android are supported by the Raspberry Pi bully, which is expected to start shipping to select developers sometime this week. There's no word on when it may be available for general consumption, but by then you'll hopefully have a better product anyway -- if the pros have done their job, that is.
Raspberry Pi lands MPEG-2 and VC-1 decoding through personal licenses, H.264 encoding and CEC tag along
Making the Raspberry Pi affordable involved some tough calls, including the omission of MPEG-2 decoding. Licensing fees alone for the video software would have boosted the board's price by approximately 10 percent. Now, after many have made media centers with the hardware, the foundation behind the project has whipped up a solution to add the missing codec. For $3.16, users can purchase an individual MPEG-2 license for each of their boards on the organization's online store. Partial to Microsoft's VC-1 standard? Rights to using Redmond's codec can be purchased for $1.58. H.264 encoding is also in the cards since OpenMax components needed to develop applications with the functionality are now enabled by default in the device's latest firmware. With CEC support thrown into the Raspbmc, XBian and OpenELEC operating systems, a single IR remote can control a Raspberry Pi, a TV and other connected gadgets. If you're ready to load up your Pi with its newfound abilities, hit the source link below. Update: The Raspberry Pi Foundation let us know that US customers won't have to pay sales tax, which means patrons will only be set back $3.16 for MPEG-2 and $1.58 for VC-1 support, not $3.79 and $1.90 for the respective licenses. We've updated the post accordingly.
