    Important to note that:

    1. This doesn’t meet any of the traditional definitions of “open source”
    2. EA isn’t using that term to describe their offer.

    Our Pledge

    Electronic Arts (EA) promises not to enforce against any party for infringing any of the listed EA patents. A list of patents subject to this pledge can be found below, and EA may add additional patents to this pledge at a later date.

    EA makes this pledge legally binding, irrevocable (except as under “Defensive Termination”) and enforceable against EA and all subsequent patent owners of the listed patents. This pledge does not provide any warranties or assurances that the activities covered by pledged patents are free from patent or other intellectual property infringement claims by a third party

    Defensive Termination

    EA reserves the right to terminate this pledge for a specific party or its affiliates going forward if that party files a patent infringement lawsuit or other patent proceeding against EA, its affiliates, or partners.

    Stupid article needs a before and after comparison.

    Instead it has way too many ads.

    “It’s a bit technical,” begins Birdwell, "but the simple version is that graphics cards at the time always stored RGB textures and even displayed everything as non linear intensities, meaning that an 8 bit RGB value of 128 encodes a pixel that’s about 22% as bright as a value of 255, but the graphics hardware was doing lighting calculations as though everything was linear.

    “The net result was that lighting always looked off. If you were trying to shade something that was curved, the dimming due to the surface angle aiming away from the light source would get darker way too quickly. Just like the example above, something that was supposed to end up looking 50% as bright as full intensity ended up looking only 22% as bright on the display. It looked very unnatural, instead of a nice curve everything was shaded way too extreme, rounded shapes looked oddly exaggerated and there wasn’t any way to get things to work in the general case.”

    This should have been easy enough to illustrate.

    Edit: Here is a greyscale illustration of a similar phenomenon:

    Of course in reality it get a bit more complex when we perceive colors as having different brightness too:

    They are targeting exactly one person that they are in litigation with.

    I don’t know about that, they seem to be saying they are looking for his associates (emphasis mine):

    In the course of our investigation, we also became aware of multiple other online actors who appeared to have a role in the Pirate Shops. However, we were unable to determine the identity of locations of these other actors with a sufficient degree of certainty to name them in the initial complaint.

    […]
    However, because Williams allegedly evaded Nintendo’s attempt to serve him, and then didn’t appear in court, Nintendo argues in its filing that this meant they were unable to find these identities through discovery, and as such is seeking the subpoenas.
