    The effect is real (I've discussed it with my eye surgeon). I think that most of the effect comes from slight distortions in the shape of your eyeball when squinting. I'd test my hypothesis but I already have 20/20 vision now (hooray for lasers).

    Well, to tell you the truth (and as someone who has worked on some of these wonders), there isn't much to learn by looking at them.

    They are essentially airplanes. I shouldn't say that- they _are_ airplanes, plain and simple. There just isn't a crew compartment. You could easily build one with a little money to buy the fiberglass and graphite and Epon and Rolls Royce engine. No biggy.

    The problem has never been, "How do I build an airplane?"; It has always been, "How do I build a reliable autonomous/remote-controlled airplane?"

    You are correct, the avionics and comm boxes have been stripped out. Comm on UAVs is the same as comm on regular fighters and bombers; it is rekeyed every day and is very, very secret. Top Secret, you might say. The rest of the trick lies in owning good satellites, well-trained techs or contractors, and money. The money is to develop the comm and C&C systems. Really- these things are RC planes, except for the C&C. It's easy to say well, big deal, I can build an RC plane... Now control an RC plane, flying over Iraq, carrying missiles, from a joystick in California. With absolute* reliability. With human lives on the line.

  11. Seriously, get a dog on Is Cheap Video Surveillance Possible? · · Score: 5, Insightful

    You need to get yourself a dog. It doesn't have to be big or scary looking- a small, yappy-type dog will do just fine. Unless you advertise the presence of valuable goods inside your house, a burglar will not break into your house if it is occupied. I think you'll find that most burglars will go for the lowest-hanging fruit, which will be your neighbor's house (unless they also have a dog, in which case the next house over is the low fruit). They want to get in, grab the stuff that is easiest to make off with and pawn, and then get out. I doubt you have any state secrets or anything like that in your house; this is a simple cost/benefit analysis for you and the burglars.

    Another thing to look into is a neighborhood watch program. Of course, if you live in a neighborhood like mine that might not be a viable option. In that case, you need to get yourself a dog and a steel-core door. Skip the expensive cameras. Are they really going to save you money?

    >>Raises, *RAISES* the question!

    I knew I would get your attention by using 'begs the question' in the first place, whether it was correct or not. I'm sure that any use of it at all would attract grammar nazis of one persuasion or another.

    I believe that I did use the phrase correctly; tfs asked "Would you buy a Metallica online album despite their former views?"

    This question presupposes that I like metallica enough to _ever_ buy one of their albums- without that assumption, the question would be meaningless. And since the assumption is incorrect, the question _is_ meaningless, and that is why I said that it begged the question. Wiki says, "[if the] proposition to be proved is assumed implicitly or explicitly in one of the premises" that it is begging the question.

    "Are you still beating your wife?" is the common example of begging the question. I think it's plain to see the parallels with tfs's question.

    "Begging the question" has a somewhat ambiguous definition in terms of modern usage. In the end, I think that being nitpicky about it is somewhat like being nitpicky about ending sentences with prepositions (a completely arbitrary rule). I mean, you wouldn't argue that "gay" still (only) means lighthearted and carefree, would you? Language evolves.

    >>Better yet, parties where we don't mention work but things we did outside of work are great because we get to see a different side of each other.

    For better or worse, some of us share the same personality between work and home. I cannot turn off "Work personality" when I leave work and turn on "Entertaining personal time" personality when I arrive home. The aspects of my personality that make me well-suited for my job are by far the most overarching and dominant out of my entire psyche. Ruthless attention to detail, literal-mindedness, thinking in terms of complex spatial relationships, rigid documentation, etc make me a good technician and a poor entertainer. Fortunately for me, I'm also probably borderline in some personality disorder or another and dislike the physical company of other people 99% of the time.

    Maybe I've had a rash of really unpleasant social interactions, but I've found 'parties' and 'conversation' to consist mainly of talking about:
    -Cats
    -What she did at work
    -People at work who have cats
    -People at work who I've never met
    -Unbelievably mundane minutiae about conversations they had with people I don't know about things that I don't care about
    -Stories about the _last_ time we all got together and did this, forming a regressive loop of such banal chit-chat that it makes me dizzy

    If I could get 15 or 20 exact copies of myself together in a room for a party, it would go like this: We'd all calculate how many beers we should each receive, we'd grab that many beers out of the fridge, and we'd all leave. The party would last as long as it would take an orderly queue of awkward nerds to retrieve beer from the fridge.

    For socially-inclined math nerds, here is my idea:
    A cooking party or pot luck where all the food is made with combinations of ingredients in mathematically interesting proportions. E.g., Golden Ratio casserole made with ingredients decreasing in a golden ratio, potatoes, cream of whatever soup, some other vegetable, etc, etc.

  17. It begs the question... on Metallica May Follow In Footsteps of Radiohead, NIN · · Score: 3, Informative

    "Will you buy a new Metallica album that is being offered like previous Radiohead and NIN albums?"

    That begs the question of whether I even like Metallica or if I would have bought their album in other circumstances. They might try this experiment and find that it was a dismal failure; I'm sure that they would point to the experience as proof of their earlier (poor) opinions of the internet's effect on music production.

    The thing about Metallica is that their music changed substantially right about the time that the internet was coming into its own as a distribution medium. Part of their low sales of albums since the black album or Load could be related to internet downloads, but I think it has much more to do with Metallica alienating their original fanbase.

    When I was a kid, Metallica was practically its own genre. I though of music as metal, country, Metallica, Pantera, punk, etc. There were a few bands that stood out as archetypes. Now that metallica is 'competing' with a larger field of music, they will find that they don't have the same rabid fanbase that they once enjoyed. When you are competing for airtime with nickelback and staind, your music is no longer special. You are a commodity like reruns of old dharma and greg episodes and your listeners will treat you with about as much respect.

    So will I buy the new Metallica album over the internets a la radiohead? No, but the reason has little to do with the internet and everything to do with Metallica's music. Music? Remember? 'Music' as in 'sounds', not as in 'financial investment'.

    You are correct; however, the similarity ends there. Quikclot is made fine mineral dust and Celox is based on a water-soluble, organic polymer.

    >>It seems that the main appeal of the new Quikclot, aside from the non-burning, is that the clotting agent is integrated directly into the gauze pad.

    Well, we've had Quikclot bandages for quite some time now- I remember seeing them in the Brigade Quartermaster catalog at least 2 or 3 years ago. This new product is based on a new mineral altogether, one that apparently doesn't burn. Which is good.

    >>Hopefully, since the agent is part of the pad, most of the hard clay clot stays with the pad once it is removed from the wound.

    Unfortunately, the bandage becomes part of the clot. Since the clotting agent is really just sort of like sprinkling saw dust on puke (same principle), the agent must be in close contact with the site of the bleeding. This is why I prefer celox- it forms a clot the consistency of thick snot, and that can be washed away without causing additional damage to the site. Quikclot and its derivatives, while they do save lives, also cause damage to the site on application and removal.

    >>Sounds like something to keep an ear open about.

    Yes, when medics buy Celox or alternatives with their own money rather than use quikclot, you know there will be intense interest in new clotting agents. I hope this one lives up to the hype.

If any of you are EMTs or just interested in having a good hemostatic agent in your kit, you should look into Celox.
