  1. Re:Take from the rich and give to the... rich on Why Mars Is Not the Best Place To Look For Life · · Score: 1

    Yeah, ha ha hah, the rich are so dumb, and they don't deserver the money they have...

    Seriously, though, put someone in power who pledges to take away the wealth of the top 1% and what do you think will happen? He'll line his pockets and his rich friends with the money, while using it to make you do something silly. Like posing like a criminal to take naked pictures of yourself before you travel....

    The problems are many, and the "populist" movements have been co-opted long ago to help the powerful cement their power.

    Rush Limbaugh would be an especially interesting choice, as his vocal patterns are somewhat influenced by his deafness, which is only partially mitigated by the installation of cyborg ear parts.

  3. Re:Loss of (or difference in) color fidelity? on Soon, No More Film Movie Cameras · · Score: 1

    Film isn't continuous either. It's layers of color filters.

    In fact, the only hope you have for a continuous spectrum is to do some kind of scanning spectral imaging setup like is done in some planetary mapping satellites - you don't get to have a 3 dimensional sensor, and I'm not sure where you'd put the diffraction grating to separate the spectrum of a 2-D image even if you could, so you have to scan a line for every frame. You're going to need a pretty bright light source for TV HD - at least 1080x as powerful if you scan vertically.

    And it gets worse. You're still going to have to deal with quantization. Only your quantization in color will be whatever dimension of the image sensor you chose for spectral info. So, instead of 3 colors you get 1,000. And secondary diffraction modes might be mixed in with primary ones.

    And then you have the problem of merging all of that into some kind of display device...

    Far easier to choose three color filters, and match them as closely as possible to the eye's sensitivity curves. Then, when reproducing the image, choose representative frequencies that are as close to separate in as many people as possible. Any photon that would register as "green" in your eye is as good as any other. As long as it doesn't also trigger "blue" - overlapping ranges were already taken care of in the input filter.

    I think that actual devices aren't even quite so exacting. But what they chose seems to be good enough. At least as good as film, anyway, and just as good in week 4 as it was on day 1.

    Digital IMAX is, iirc, 2 * 2k projectors, which is not quite 4k, even if the pixel count matches (I don't know the vertical resolution, for instance...) I don't know what it's shot at...

  5. Re:And for good reasons... on Soon, No More Film Movie Cameras · · Score: 1

    If the editing software companies are smart, they're saving the *actions* of the editor as well as the raster results. That way, the edits can be replayed later at a higher resolution, which is probably sufficient for most of most films - there would likely be areas that need more detailed editing, but that would be a much smaller expense than re-editing an entire film.

    Frankly, I'd be surprised to find that ships over a certain value don't pretty much universally include an inertial nav system in their standard equipment as backup. It shouldn't be too expensive any more, what with the development of MEMS accelerometers and such. In fact, I'd bet there are rudimentary iPhone apps that sort-of work over small distances.

    Or, maybe they're just not as well publicized. I haven't seen any statistics either way comparing the actual number of incidents to other denominations or to the general population. The institutional problem was the cover up, which thwarted justice for the victims.

    not if what you want to practice is the countermeasures themselves. You can't track a GPS jamming signal without having a jamming signal to track...

    You can simulate it with other bands, but the equipment is not quite the same, so you won't get the same practice. At some point you have to do the real thing.

    That depends on how powerful your search terms are.

    If you're looking for "every email for X project" then yeah, folders might be better, but if you're trying to find a piece of information from any particular project, you can almost certainly devise a set of search terms that specify what you're looking for more precisely than "it's in the folder."

    Only primitive email software won't allow combinations like "and, or, and near," wildcards and assertions like date ranges, senders, recipients, subjects and the like.

    The constitution does not grant rights to the people. It "grants" powers to the government.

They were not intended to be a full enumeration of the rights of the people, and indeed, rights not specifically protected may have at the time been considered so obvious and fundamental that there was no need to mention....

  20. Re:Loyalty and Outsourcing? on Ask Slashdot: Does Being 'Loyal' Pay As a Developer? · · Score: 1

    It might mean nothing, maybe. It's possible that they had a short term thing that needed to get done and they outsourced rather than grew to accommodate the brief spike in additional workload. One advantage of outsourcing is that you have more control over when the relationship begins and ends.

    It's even possible that it was not cheaper than they could've done it for in-house if they had the resources, but developing those resources would have been prohibitively expensive at the time.

    The truth is never in the middle. Sometimes the truth isn't even on the same axis as the claims. The truth is what the truth is, and you can't find it by simply averaging the claims of interested parties.

    The truth, in this case, is that the ISPs are balkanized monopolies. Except for a few places, you've only got one or two options in any given area. Since there's no real competition, they can basically charge what they want. The costs don't really come into it.
