  1. Two words: "stagnation temperature".. on Stratospheric Skydiving · · Score: 1

    When this guy does his dive, I really hope whatever hits the air first is well insulated. The air density may be low, and the temperature won't be terribly high at M1.4, but any part of his body generating a shock wave is going to heat up to some extent. I'm sure that's been taken care of, but it could be rather uncomfortable for, say, fingertips ..

  3. As much as I like the idea .. on Canada Considers Cellphone Jammers · · Score: 1

    In a position paper released in November, the Mobile and Personnel Communications Committee of the RABC said, in part, "Denial of service of (especially emergency service) may have legal repercussions on the service providers, Industry Canada, the jammed provider and the public venue operator (concert hall etc.) where some perceived harm or loss has occurred, particularly in situations where lives could have been or were lost."

    As much as I would enjoy seeing the obnoxious guy in the cinema get an earful of +20dB static, this could have some extremely bad spinoffs.

    Say someone's having a heart attack or an anaphylactic shock episode in the theater, and their SO is trying to call 911 to get EMS to save their life. Oops -- can't do that, sorry ..

    Or, say someone with a (gasp) *illegal* jammer decides to block cellphone calls, say, to facilitate a robbery. Robbery victim dials 911 and continues to hit SND-END-RCL-SND- until knocked unconscious or shot.

    I could go on.

    Here's a better idea: If you want to control cellphone use in your venue, don't indiscriminately block all cellphone access. Make the arena reasonably RF tight and set up microcell transceivers on the ceiling that accept emergency calls and reject all others. (Design of these things is left up to enterprising developers, but it is possible..) Presto -- no lawsuits, no interference with other services, and the best part is, when someone *does* call 911, they don't have to backtrace to the nearest tower, they know exactly where you are and can find you RFN. ;-)

    Yes, I know, it's unethical, rude, thoughtless, and selfish of people to use your open public share as a cache for things they don't want to store on their own drives, but allowing public write access to *any* directory on a machine you own and/or "administer" is about as smart as running your HTTP server as root and passing URL text to the shell. If you don't understand why either of these are bad .. well, you shouldn't be setting up any public shares.

    It boils down to what you NEED. Computers are nothing more than tools that do a job. If you current computer does everything that you bought it for, then use it. If it doesn't, maybe you should use a different OS until your current OS supports the features that fit YOUR NEEDS. Personally, I've been using Macs since about 92. I have NEVER thought to myself, "Crap, I need to use Windows to do this" MacOS fits my needs. It may or may not fit yours.

    Same here, though I've been using Macs since 83, and have used every model and OS version since System 1.0 on a 128K Classic. ;-) Personally, Mac OS 7.6.1 and ClarisWorks 2.0 are all I've ever really needed to do what I need to to with a computer. I'd like a dual G4 running OS X in a dual boot with its own 9.0.4 for Classic and 9.1 on the OS 9 partition, but I don't need that much power to do word processing or the simple graphics I need to do. WinXX is not enough of the right kinds of functionality to be a serious system for me, and too much of the stuff I don't want to be worth hassling with .. there are a few ham radio apps like DigiPan that won't run on a Mac, but I'm not heartbroken that I can't use them ..

  9. Re:Some scientific information on Changing Earth's Orbit Proposed · · Score: 1

    While it will probably never be used to actually move the earth, the same techniques could be used to move things (spacecraft, asteroids for raw materials, etc..) without vast expendature of fuel as is currently done, where much of what we do is the brute force method. I read a paper that described how to get a spacecraft to the moon using less energy than a homan transfer (the most efficient way we currently change orbits). The method used the fact the earth, sun, moon system is a chaotic 3 body system. The drawback was that it took years to get the spacecraft to the moon.

    I think a more useful trick would be to exploit a cislunar trajectory to get a boost out of the moon's mass and kinetic energy. The moon has no atmosphere, so you can get away with a very close approach that would add a significant amount of energy to a spacecraft passing it from down-orbit.

    Apollo used a translunar trajectory to get the exact opposite effect -- extracting just enough energy to produce a free return to earth -- but a cislunar pass would probably kick the spacecraft into a solar orbit. If you tune the approach just right, you can get an almost free interplanetary boost and maybe even make a Mars transfer .. something to think about ..

  10. Filtering by machine never works. on Slashback: Blockage, Stripes, Upswings · · Score: 1

    Another interesting little tidbit: Microsoft ran into a similar spam-related problem three years ago when it tried to block unwanted e-mails by filtering out incoming messages from Outlock 98 that contained certain phrases or grammar, such as a string of exclamation points or the words "for free." As a result, many people found that they never received messages from friends who were fond of multiple punctuation marks. Could have told them that wasn't going to work .. almost wish I could have gotten paid for a consulting report on that one. ;-) I have friends who when they get pissed off enough tend to string together lots of exclamation points, and other friends who would probably hit on keywords pretty frequently. Then again, we know from the ongoing censorware saga that filtering by content is worse than useless ..

    This does explain a lot, though, about why a certain listserver a guy up in Dallas administers had to migrate its whole list to eGroups because Hotmail, Yahoo, and AOL were almost always IP blocking, or rejecting messages over a certain recipient per hour quota, or any number of other forms of useless bullshit. Before he gave up in disgust, he was getting complaints about 2-3x/day about posts either not getting to list members or not appearing on the list at all, and guess which providers *all* these members were from? Hotmail, Yahoo, and AOL. Sigh ..

    OK, so now we *know* they're deliberately dropping stuff in the bit bucket because they don't like where it's going. What's next, filtering to /dev/null because of content they don't like?

It's fun watching them try to steer me away from their iMacs and iBooks over to the PC aisle, especially when they realize I'm not going there.

    Mind you, this is not as bad as it gets. This 13,602,000,000 is the annual allocation; it costs NASA something like 270,000,000 to launch one STS mission, and that's for a typical mission. Now that ISS (or at least some of it) is in orbit, a lot of that budget is going to go toward keeping it in orbit, maintained, fueled, powered, and populated, and they have to seriously stretch the capabilities of the STS spacecraft for some of these construction flights.

    We are definitely losing out on some missions that should really be looked at seriously at this point, one of which (manned Mars mission) was promised by the elder George Bush in a pale imitation of JFK's "land a man on the moon" speech. We haven't landed humans on Mars yet. We haven't even landed humans on the Moon in the last 28 years, thanks to a major funding cut by Congress in 1971 -- if NASA had a budget of 279,924,000,000, we could do both.

    I know, I know, we all want what's best for the child, and we want the child to have the best possible opportunities and so and so forth. Fact is, the best thing is to hold off on trying to cram information you think is important into the kid. Odds are he/she is *already* better equipped to figure out what to explore than you are, and will be attracted to the things he/she has an aptitude for. I know this was true in spades for me, and if I had had the chance to break into the bleeding edge stuff on my own back when I originally had the desire, which was around the time I was 9-10 years old .. well, I'd probably have been a .com and be traded on Nasdaq about now.

    I guess there's a question of level of sophistication involved. I know on both the Macs I use I would be very suspicious if strange new extensions just appeared in my system folder, or random bits of innocuous looking hardware just appeared at my ADB or USB port connection -- I'm certain anyone who's familiar with their Registry contents would be equally concerned if new keys started showing up in there.
