    So you want defense against snooping but don't care about defense against MITM attacks.

    Yes, that's exactly what I want as the minimum requirement. Snooping on traffic is incredibly simple to do, and can really be done easily by anyone at any point along connection path. You just start up a packet sniffer, grab random packets, and wait until you catch something interesting. You don't even have to catch an entire session. Successfully pulling off a MITM attack is MUCH more complicated...requiring something trickier, such as hijacking DNS. You can't just be at any random point along the chain and perform the attack on any random connection coming through.

    It's like a lock on my front door. I don't delude myself into thinking that nobody can get into my house, but the lock is a safeguard against the easiest attack vector.

    I should also add on to my last post the following:

    The other danger with oxygen is that not only does it make things burn quickly, but it makes it difficult to extinguish. So if you are working with fire (say, trying to set an office supply cabinet on fire) and a spark jumps to you and sets your clothing on fire, normally you could just pat it out, or if worse, do the stop-drop-roll technique or use a blanket to smother it. The problem is, with concentrated oxygen those techniques often don't work very well because you can't remove enough oxygen to interrupt the combustion.

    No, it is NOT a myth. Did I say that oxygen was flammable? No, because it isn't. However, in the presence of concentrated oxygen (vs the concentration normally found in the atmosphere), fuel will burn MUCH MUCH quicker. Things that would normally burn at a very slow pace can go up in flames in just a few seconds in pure oxygen. Dropping a hot cigarette ash on your clothing would just normally smolder for a second, cause a burn mark, and then extinguish itself. In the presence of concentrated oxygen, however, that same ash can cause your clothing to go up in flames quickly, causing severe burns.

    So of course it's not dangerous because it's flammable. It's dangerous because it can turn a minor fire into a blaze very quickly.

    The underlying assumption (miles per year and $/gallon) are both printed on the label.

    ...

    They are going to be consistent for all vehicles in the same class and the same model year, so in the most common cases of comparisons, the variations won't matter.

    But that's not the point. This article was pretty clearly talking about a situation where a 2 car family is trying to figure out which of their 2 cars is going to be the most beneficial to upgrade. For that to happen, you are going to need to know the figures for your existing vehicle.

    Its a fairly trivial one-time calculation to convert your existing cars rating (presuming you got a car from a model year after the EPA adopted the current methodology) to correct it to the gas price used on labels for the current model year (just multiply the total estimated cost from your cars rating by the the new labels stated cost per gallon and divide by your labels cost per gallon; you've then got a number you can use when comparing against any car from the current model year.)

    LOL...yeah, right. You are talking about the same people who can NOT figure out whether 10->20 will save you more than 33->50, and now you expect that they are going to be able to make this calculation on their own?

    Of course, this is all a moot point because (as others have already pointed out) it is very rarely financially advantageous to replace an old car with a new one. If you keep your old car and spend X dollars extra on gas (compared to the car you would have bought) and spent Y dollars in upkeep, X+Y will generally be less than the financed cost of the new vehicle minus the residual value of that new vehicle. So, for most people, it really only makes sense to replace a vehicle when it no longer suits your needs (it has become too unreliable, is not safe, does not meet your new family needs or your cargo needs, etc).

    And even if we go with the fact that the family is probably not smart enough to realize this and will thus upgrade one of the vehicle anyway, we still need to know the ratio of usage between the 2 vehicle.

    But if we kind of put these 2 problems aside and just discuss within the premise of the article (no matter how faulty), then "annual fuel cost" figures are no simpler for people to correctly analyze than the MPG figures are.

    You do realize that the current EPA fuel economy sticker already has a consumption measure -- in terms most people understand more readily than gallons-per-mile -- dead center, right?

    The problem with that figure is that it has to be based on some set cost per gallon of gas. That means that, periodically, those figures are going to change. Then years from now, when I consider buying a new car, it makes it more difficult for me to compare my current car to cars on the market because the 2 figures are based on 2 different cost-per-gallon figures.

    So I buy a car with a fuel cost of $925 per year, then in a few years I'm looking at another vehicle with a cost of $1160 per year? The baseline gas price used to generate the estimate has gone from $2.82/gallon to $3.77/gallon.

Had I repeated this process up and down the street I could have probably determined with a decent level of accuracy where each wifi network was originating. And all that was without me snooping in on peoples HTTP sessions and such.

    Are they that bad? Well, lets see. The last time I had them, I had no internet service for 3 days. After repeated calls and a tech coming out I got no resolution. Finally I took it upon myself to install a packet sniffer, and what do you know...all of the IP traffic on my subnet was in an entirely different range than the IP I was being assigned. I picked a random IP in the valid range that appeared to not be in use and statically assigned it, and *mysteriously* every was suddenly working. I had to wade through first level tech support, convince them to let me talk to a network engineer (because he had no clue what I was talking about), and then tell that guy how to fix my internet service.

    Then there is the billing department. The bill is conveniently itemized so that you can see the comcast charges, and then separate entries for the franchise fees, city taxes, universal service fees, etc. Comcast raised the bill by exactly $1 with absolutely no mention in any of my previous 6 bills about a coming change. That $1 increase was in the line item for the comcast charge. Yet when I spoke to the billing department, they were insistent that they absolutely did not raise the rate on me, and that the increased charge was solely due to city taxes. Even showing them my previous bill and pointing out exactly where the increase occurred could not budge them. They blatantly lied to me, and continued to lie even when shown evidence that they were clearly lying.

    Now, compare that to WOW, where I can personally email the CTO directly about a problem, and he'll happily respond with a technical answer, and even admit fault if something went wrong on their end. Or with the install techs, who routinely show up in the first 30 minutes of the 4 hour service window, instead of the last hour (or even after the 4 hour window). And those techs are always willing to chat with me about how much better WOW treats them and makes it easier to do their job.

    yeah, comcast is that bad. I kind of feel bad for the comcast guys that come around to my door every now and then trying to get me to switch back.

    I'm saying that a 12 bit image means you have inserted 3 extra levels between each of the levels of an 8 bit image. Assigning magical properties to this is a mistake. Most of the magical properties people are assuming can be made available by using floating point.

    What are you talking about with respect to "magical properties"? Those 3 extra bits give you a little more differentiation in colors. When you are in deep shadows you tend to get blockiness as the slightly different colors get recorded as the same color due to a lack of bits available for recording (it's sort of like rounding off 2 different numbers and ending up with 2 of the same numbers). With the extra bits, there is more precision and fewer of those colors end up being recorded the same. This becomes especially noticeable when you use an editor to try and brighten up the shadows. That's when the difference between the 8-bit and 16-bit versions will start to really become noticeable.

    If you convert your image to display correctly on the screen then you must have more bits than the hardware produced, otherwise you will have lost data, due to the pigeonhole principle.

    2) Which cameras capture floating point data natively?

    At the lowest hardware level most are using digital counters. However the conversion software coming with the camera often does use a floating point api. The RED camera is a good example.

    But it does no good to convert it to floating point unless the sensor is natively capturing floating point data (and to my knowledge, there are no sensors that do so). The conversion gains you no precision in data so there is no upside. On the other hand, there is the downside that the conversion needlessly makes your file size grow (by nature of its design, a floating point number requires more bits than an integer to losslessly store the same range of valuesas that integer.)

    Now, if someday sensors were capturing very high bit data (lets go a bit extreme and say we had 1024 bit sensors), it might be decided that we really don't have much need for such precise data, and that we'd like to maintain that dynamic range without the huge file sizes. Then it would make sense for the cameras to record in floating point, throwing away some unneeded precision in the brighter areas in exchange for a more manageable file size. But that time is not now. We aren't there yet, so a floating point format gives us no gain, but it does give us the downside of a pointlessly larger file.
