Over 600 comments and no Soviet Russia jokes yet? This must not be Slashdot...

Don't forget there is also a partial solar eclipse happening on May 20 in the Western U.S. More info here:

I can't count the number of times I've submitted a post where I noticed an error right after clicking submit. It happens even when using preview. Being able to modify our comments after submitting (at least for a few minutes) would be a nice addition.

How do you know that is what the poll option was based on? Also, The Lottery isn't science fiction, it's fiction.

I'm surprised nobody has mentioned this already, but there was a Sliders episode with a lottery used to choose who dies: http://sliders.wikia.com/wiki/Luck_of_the_Draw

Here is the LM YouTube video regarding Space Fence: http://www.youtube.com/watch?v=7SJdN90vT04

Good to know. I guess it isn't that the microphones are defective (as they're capturing the sound fine), it's that sometimes nobody catches and removes those frequencies. :^) I've heard it with mics on people as well, so I don't think it's limited to just foley.

Yeah, when a CG or animated scene is intentionally defocused that is only because the director is forcing you to view something or to avoid distracting you with background detail. Or it's possible they just didn't do their job right. For example I've lost count of how many movies had very loud and shrill (but occasional) 14-20 kHz tones coming from defective microphones that nobody caught before the movie was released.

In order to have everything in a scene in focus with conventional equipment, you have to collimate light using a very small lens aperture. The drawback to doing this is that you get much less light into the lens, which makes filming anything other than brightly-lit scenes impractical unless high ISO speeds are used. An exception to this rule is CG and/or animated scenes, such as what was employed in TRON: Legacy. You could also use a plenoptic camera to capture the entire light field. In "real life" not everything you see is focused... for example, if you look at something two feet in front of you, the objects in front of and behind that object (in your peripheral vision) will be out of focus. This is more apparent in lower light, as your pupils (analogous to a lens aperture) are wider which cause your depth of field to be lower. Wikipedia talks more about this in their depth of field article.
