Comment This is actually old tech. (Score 3, Insightful) 58

The ability to convert a spectrogram to sound has long been known in the speech research community. In 1950 a device known as the Pattern Playback was built at Haskins Laboratories. You would draw an artificial spectrogram and feed it to the machine and it would play back the corresponding sound. It was used to perform experiments on the acoustic cues for speech perception. The original machine was last used for research in 1976. See the Wikipedia article: https://en.wikipedia.org/wiki/...

Supporting Windows XP means modifying it to deal with changes in hardware and patching bugs, especially security problems. That requires on-going effort on the part of Microsoft, so it is understandable that they will not keep at it indefinitely. (You would, I imagine, justifiably feel ripped off if a year after XP came out Microsoft dropped support.) Keeping a game playable in the sense required by the bill just requires the publisher either to keep the server running or to distribute a version that allows players to run their own server. Neither of those requires the kind of ongoing effort that continued support for an OS would.

This is interesting but it is only half-true that the use of consumable chemicals has been the barrier to the creation of scent emitters. The other problem is that no orthogonal basis for olfaction is known. In the case of color, for example, we know that you can combine red, blue, and green to form any desired color. There is nothing comparable for scent. We don't know that you can use, say, rose, bitter almond, and sandalwood to create any desired scent.

Comment "bright as a full moon" (Score 3, Insightful) 80

You can stare at the full moon all night if you like, because the albedo of the moon has filtered most of the light including the UV band that naturally passes through our own atmosphere. The three mile circle illuminated by a mirror would bounce a significantly higher amount of UV than the moon's albedo. If you treat the 60ft reflector as an analog to a pinhole in a pinhole camera, the circular area on the Earth surface would be a rough projection of the image of the sun.

(1) I wonder how they calculate the UV exposure for the observer on the surface within the illumination area.

(2) I wonder if you'd be able to detect places in a coherent projection where sunspots or coronal ejections are reflected through the "pinhole" effect of this arrangement.
