According to that discussion, the player is based on the STB225 set-top box platform designed by NXP. At the center is a chip called the Nexperia Multi Format Source decoder PNX8935, which combines a 32-bit MIPS processor and a dedicated video decoder supporting multiple codecs, including H.264. The reference STB225 boards have SATA and USB capabilities. The Wi-Fi daughtercard in the Roku box uses up the USB header, but there are several other headers that have yet to be identified. Roku engineers say that the box uses HDCP on the HDMI connection, which might limit its hackability.

On the software side, Roku has released the source code to all of the free software used inside the box, including the Linux environment and bootloader.

From virtually nothing in 2000, the industry today can boast 1.5 GW of installed offshore wind capacity, of which 334 MW – more than one fifth – was installed in 2008 alone, see Figure 1, (below). An additional 1.5 GW is currently under construction, and Douglas-Westwood forecasts more than 5 GW will be in the water by 2012.

Using a device called a trampoline, a function could return a function which needs to be called. Observe:

function add ($x, $y) {
if ($y > 0) {
return array (”add”, $x + 1, $y - 1);
} else {
return $x;
}
}
$f = array (”add”, 6, 5);
do {
$func = $f[0];
$f = $func($f[1], $f[2]);
} while (is_array ($f));

It’s hardly pretty (though implicit evaluation improves this drastically over other methods) but it’s not awful and makes some things in PHP possible that would otherwise require writing an extension in another language.

The proposal would ban BPA from food and beverage containers. Proponents say the precautionary principle requires such a ban because high doses of BPA can cause reproductive abnormalities and cancer in animals.

But whether you agree with that stance depends on how you define the precautionary principle. It's not written into federal law, and it turns out that people have widely differing views on what it is, and how it should be applied.
