  1. My favorite example ... on Law Profs File Friend-of-Court Brief Against RIAA · · Score: 4, Insightful

    Someone once pointed out that under the "making available" theory, most men with a wife or girlfriend could easily be charged with involvement in prostitution. After all, if a man leaves his woman home alone or lets her go out in public by herself, she could very easily make herself sexually available to any passing man.

    This isn't entirely hypothetical, of course; there are some parts of the world where men do take this attitude.

    Somehow, I think I'd rather not have such legal theories adopted where I live. I think my wife would agree.

    I've also noticed that we often have tools like knives lying on our kitchen counters. Those knives have often been out, and even used, when we have visitors. Kitchen knives could be used to kill people. So are we "making available" dangerous weapons when we give visitors such easy access to our kitchen knives? (Sometimes we've even put steak knives on the table, knowingly and with the intention that they be used. ;-)

    It's more like your temperature will fluctuate over periods of hours like 98.401, 98.737, 99.013, 98.632 .... Any digits past the second are meaningless medically. They're probably also bogus technically, unless you've left the thermometer in exactly the same position the whole time (and insulated it from air contact if it's near the skin).

    That 6 in 98.6F is a textbook example of false precision. And it doesn't even come from averaging any measurements; it's an artifact of converting 37C to Fahrenheit. A much more meaningful estimate of normal human body temperature is 37C plus or minus a degree. If you convert that to F, 98.0 and 99.5 are both within the "normal" range.

    I've read half the thread now, and you're the first post that halfway resembled being on topic, although unintentionally so.

    It wasn't entirely unintentional, though it was mostly in reaction to the silliness that followed the summary that just said "70 degrees" without mentioning a scale. I was also sorta tempted to mention that there were probably error bars of several degrees in the researchers' measurements of leaf temperatures, for fairly obvious reasons. Bogus excess precision is a constant complaint that many scientists have with the media, and this topic is rife with it.

    We've had a lot of hints that many plants have the ability to somewhat control the temperature of various parts. Here in New England, a common spring "flower" is the skunk cabbage, whose flowering structure has an internal temperature in the mid 30's (Celsius), when the ground and are are still both barely above freezing. Out on the Midwestern prairies, there's the "compass plant", a kind of sunflower whose large leaves are oriented north-south, and the standard explanation is that it's to absorb sunlight in the early morning and late afternoon, while avoiding a heat buildup from the mid-day sun. And so on.

    But measuring the internal temperature of a leaf is a bit tricky, and we've only had tools to do it for a couple of decades. It's interesting to read of research showing that some plants have evolved ways of controlling their leaf temperatures to within a few degrees of an optimum temperature.

    I'll bet that a lot more research is needed on this topic (and might be supported by the obvious horticultural implications of the knowledge). We can expect to hear more about it in a few years.

    And if you post something in an international tech-oriented forum using idiosyncratic units used only in your country, you gotta expect that people will mock you. In this case, it seems that most people did the mocking not by being nasty, but by (trying) to be funny about it. I'd say that in this case, the /. crowd has responded quite appropriately to a rather silly gaffe. It's a lot more entertaining than the usual outburst of insults.

    So how do I get the units in /. articles like this automagically translated to what I'd like? Seriously, if there's a way to do it, I'd like to know. I can conceive of ways to do it, but it'd either require me giving appropriate locale-type info to /.

    Hmm ... I've long since decided the opposite. America is the one place in the world where I have to have two sets of nearly every tool and measuring device. Life would be simpler if I could dispense with one or the other. In some cases, I've done so. Thus, I haven't owned an American-made car since the early 1970s, so I only need metric auto tools. I've let the old ones rust, or I've given them away. (Cue the jokes about the difficulty of finding good metric pliers, crescent wrenches, etc. in the US. ;-)

    I do have a number of measuring tools that combine both English and metric, so I don't need duplicate tools there. But the combined tools are sometimes awkward. Thus the tape measures have English on one edge and metric on the other, and this is sometimes a hassle if I want to hook the little hook over something too far away to reach and unroll the tape to take a measurement. Half the time, the units that I want to use are on the "wrong" edge. This isn't a huge deal, of course, but sometimes being off by a mm means a bit of hassle cutting things to fit smoothly.

    It isn't something that I'm a fanatic about, but I'm aware that being forced to use a mixture of two incommensurate measuring systems produces lots of little niggling inefficiencies and minor errors that could be avoided if everything used the same units. It's more annoying than serious, and its one more ongoing illustration of the clumsy "Who cares?" attitude of much of our society.

Attempts to calculate an average temperature of a crowd of humans will turn out different in the third decimal place depending on which humans and which measuring tools you use.

    The conventional 98.6F temperature comes from converting 37C to Fahrenheit. The 37C temperature is also "plus or minus a degree or so", but it doesn't have fake precision from a third digit.

    According to many people here, we are criminals. I consider this nonsense. A bunch of us in the neighborhood run open wi-fi access points as an act of friendliness toward each other and visitors. The wi-fi part of the spectrum is officially supposed to be open and usable by anyone, just like the public road system. Considering us criminals seems anti-social and obstructionist in the extreme.

I can even use Preview instead of Acrobat, and get a bit more vertical space for the page.

    And, rendering PDFs in Safari and Opera is slooooow. To see why, just try opening the same page in Acrobat. The first page takes forever. The second might be faster, but then you have the problem that you'd be adding Acrobat's memory requirement to the browser's memory requirement permanently. Safari and Opera grow huge permanently when a PDF is opened, even after you close the tab that it was in. Maybe they'll fix this some day, but then all PDFs will probably be slow to open. Firefox's approach of opening a subprocess is better. You can just kill the subprocess, and the memory is freed up for reuse.

    It was nice of them to make firefox smaller and leaner. Fattening it up with a cancerous elephant like Acrobat isn't what we need. OSX is a multiprogramming system, after all. It can run parallel processes just fine. Displaying PDF files is a good use of this ability.
