    I don't really give a shit.

    According to your site, you do give a shit--all over Linux. Sorry, couldn't resist.

    However, this is a good point. I use BSD and I use Linux. Instead of taking pot-shots on mascots and such, perhaps we should state why our favorite OS/App/Whatever is better. Perhaps instead of "Because BSD Shits All Over Linux" it should be "Because The Others Use BSD Libs Anyway!" or something of that sort. Saying BSD shits on Linux does nothing to sway my use of Linux.

    Also, merely a technicality, but if the BSD Mascot is pitching anal and Tux is catching, wouldn't it be BSD which is getting "Shit All Over" it?

  4. Re:Wrong... on T-43 Hours and Counting · · Score: 1

    Weather is measured by single data points called "Weather Stations." NOAA with their "gridpoint forecast" may average statistics between these stations to give a custom forecast between the two. However, at this point, we've moved farther from the data statistics that help to give us accuracy. i.e. it's highly speculative--and likely doesn't account for geographical features and cannot account for the highly unpredictable nature of weather. Especially for "scattered showers" and such.

    So...

    If it is "70% of the times we noted these weather conditions, rain occured", then that 70% is a much higher percentage than the actual probability that it will rain on me. This is because (probably) most of those "70%" of times did not see rain falling on every square meter of the prediction area.

    The meteorologists do not have instruments on every square meter of the prediction area. They've got instruments at one or more weather stations. And the 70% is for how many times the rain occurred at that station under similar conditions (temperature, pressure, humidity, etc.) In all ways, a weather reading is a single datapoint, and since these statistics are derived from a single datapoint, they are singular as well. However, as I mentioned above, these things can be averaged between stations.

    I'm guessing your "area coverage method" is some kind of averaging of these weather stations calculated statistics.

    I found this explanation as well:
    http://www.theweatherprediction.com/habyhints/284/

    The interesting parts:

    When referring to POP it is most accurate to say, "There is a ___% POP that any particular measurement station in the viewing area will get precipitation". For example, when averaged over many 30% POP days, a particular station should have precipitation 30% of the time if the forecaster or computer model is accurate.

    and

    All to often, people assume a 20% chance of rain means 20% of forecast area will get rain on that one day. This is often not the case for any one day. Often no precipitation occurs at all in the forecast area on days with a 20% POP since one component of POP is the chance that any precipitation will develop.

  5. Re:Wrong... on T-43 Hours and Counting · · Score: 1

    Or using your method, conditions in which rain is already present leads to a 100% chance of rain?

    Well, if the rain is already present, it isn't much of a prediction, is it?

  7. Wrong... on T-43 Hours and Counting · · Score: 2, Informative

    Actually I worked with a bunch of meteorologists.

    Anytime you see "70% chance of rain" it means that of all the noted times that similar weather conditions occurred, 70% of those times the weather conditions resulted in rain.

  8. Priming the pump on Water Now More Awesome Than Previously Thought · · Score: 1

    Well, and it's not like you have to start with a dry pipe. Just take surface water to fill the pipe first, then your siphon works from the beginning. Of course the first bit of water will be room-temperature, providing no temp-differential.

  9. Fluid Dynamics & Thermodynamics. on Water Now More Awesome Than Previously Thought · · Score: 1

    How about fluid dynamics? Let's start out simple, okay?

    When I was growing up, we had an above ground swimming pool. When it was time to clean it out, I'd stick one end of a garden hose in it, then the other end down the slight decline of a hill. After that, I would then suck on the downhill end of the hose to start a siphon. That hose would continue dumping out water all day until the seal was broken (air entered the hose from inside the pool.)

    So let's apply this to a larger scale. Say the top of the pool wall is an island. The bottom of the pool is the ocean floor. Also, let's take the downhill end of the hose and put it back in the pool (the ocean.) Now, in this configuration we're not siphoning downhill, so we have to pump the water to keep it moving--however--the same laws apply and the water travelling down is creating a vacuum which pulls the new water up. Think of how the front of a roller-coaster pulls the end of it over the crest of the hill.

    So that's your "perpetiual motion" machine. Something that requires minimal energy to keep going. So how do we keep it going? Well, the laws of thermodynamics still apply and the real catch is in the payload that we're pumping up. On average, there's at least a 15C/30F difference in temperature between the ocean water we're pumping and the air/water at the surface. Any physicist can tell you that this temperature difference can be called "potential energy" and can be harnessed in many ways (In the article, it talks about using a vacuum and turbine, but also a stirling engine could be used.) However you harness this potential energy, a portion of it can be used to continue the pumping.

    Saying that the water pumped up from the depths of the ocean is a simple "perpetual motion machine" is simply folly as the energy is not produced from the pumping, but from the temperature difference delivered via the pumping.

    Okay, the FAA controls the US airspace, right? So, they probably won't allow any of these LEO Billboards to be launched in the U.S.

    Of course, there's virtually nothing they can do if an LEO craft is launched from some other location and meanders over the U.S. from time to time.

    Perhaps they could do something if it were placed in a geostationary orbit over the U.S. but then it wouldn't be in LEO.

  25. Lens Reflection on Automatic Scanning for Cameras in Theaters · · Score: 1

    First off, any refractive surface is also reflective at the right angle. Since all cameras include at least one refractive surface in the lens, this can be isolated for a reflection. So, therefore it is not impossible to detect passive videorecording because video is much different than audio in the fact that it does not reliably bounce off of most surfaces, requiring a direct line-of-sight between the recorder and subject.

    However, it may be true that it will not be set to scan the projecting area. This would probably be difficult because it's behind a window and next to a very large directed light source (the projector.)

    Even though you may not be willing to subject yourself to "light impulses" and such, there are many, many consumer sheep willing to do so--with their knowledge or without. So therefore, your dollar vote matters not.
