  1. Pilot vs. Engine on Human Powered Paper Airplane · · Score: 4, Interesting

    Paul MacCready had the Gossamer Condor and then the Gossamer Albatross -- two famous aircraft, to be sure.

    A group at MIT built the Light Eagle and Daedalus.

    In both cases, the pilot was in as complete control of the craft as I can imagine; providing both power and control input. Daedalus had a... problem... I believe it was a gust of wind that put it in the surf off Santorini beach. Perhaps, if the pilot had not been so exhausted from being the engine as well, that might not have happened. Good argument for flight controls that don't get tired.

    Then there are people like me (an occasional sailplane pilot, more seldom than I'd like), who would rather not have something else be in control of a craft that is so vulnerable to the whims of the wind.

    You mentioned the pilot "most of the time" is the electronics. How much control does the human engine actually have? (Just curious...) Granted, it'd be rather nice to have the 'highway in the sky' that NASA and Paul Moller keep crowing about...

    It's rather ironic, actually, that this testing is happening on Boeing's home turf. The attitudes of Boeing vs. Airbus with regard to computer control used to be 180 apart: Boeing's computer systems would default to what the human pilot believed was necessary, while Airbus had a system that limited what the pilot was able to do. In effect, Airbus' computer design had final authority. I believe this changed after the A3xx airshow crash (when the pilot tried to apply power and ended up in the trees anyway), but I haven't heard anything about this for several years.

    I hope more enlightened attitudes have prevailed.

  2. Hey, this is local! on Human Powered Paper Airplane · · Score: 5, Informative

    Paine Field is about 3 miles away from my house, if that. It's right across the 'street' from the Boeing 747/767 assembly plant -- you know, the "world's largest building"? (Largest, I suppose, in that it covers more land than any other building -- it's not particularly tall.)

    I saw a news bit recently (last night?) about the crash... looked like one of those 'impending doom' situations, where you know things are going badly, and there's nothing you can do to stop it. Unwieldy looking landing gear, but necessary for the size of the prop the fellow is turning. I'm amazed there was as little damage -- it looked worse.

    Here are some links from local news:

    Doesn't look like the pilot has much for visibility. It's one of the most recumbant positions I've seen for human-powered flight. When they were pulling him out, it looked like he's almost strapped to the underside of the spar!

    Incidentally, the Boeing hangar (the 747 assembly building) is where some of the human-powered helicopter (!!!) tests have been conducted. It's the only indoor place large enough, and the tests have to be indoors because they need absolutely calm air.

  3. Beyond 'fixing' a car... on Techie, Wrench-head, or Both? · · Score: 2

    I find there is much more to it than 'fixing it when it breaks'. It's an issue of preventative maintenance -- fluids (not just oil!), brakes, shocks, and other moving parts. I have a tendency to keep a car so long that I need to replace the clutch. If one takes proper care of a car, pays attention to what noise is normal (and what isn't), then you won't end up playing catch-up.

    Just like windows systems need regular anti-virus updates and other patching, cars need their attention, too. I've bought the Bentley manuals (2-inch thick complete reference books) for every vehicle I've owned, and (for the most part) I follow the maintenance schedules. As a reward, my cars are reliable, and I'm not shackled to a bank via a car payment. The car is mine, period, and I like it that way, thanks.

    Another issue comes into play when one is willing (and capable) of such mechanical and electrical prowess -- used cars are a lot less expensive, and when purchased from individuals, you never have to interact with slimius vulgaris Rex, also known as the (used) car salesworm.

    I have owned Volkswagens exclusively for 15 years now, and I've been able to appreciate the engineering that has gone into each one. You can see the thought that went into the evolution from original I-4 gas & diesel engines to 15 V-6 (VR6) to the 1.8t & TDI engines popular now. Each one of these has been interesting to work on (I can't absolutely say "fun"), and at least logical in their assembly. The evolution from mechanical/electric to solid-state systems has been great in my opinion; it makes things easier, more powerful, and more efficient. (I especially appreciate OBD-II)

    I find that the more I have worked on my cars, the more easily I can diagnose noises and problems. I won't hesitate to dive into an A/C compressor replacement (with its associated 'gotcha's and other 'mandatory replace' components), and repairing a power window is something I can do in an hour after work.

    On the other hand, I watched a fellow try to change spark plugs on a Mitsubishi 3000 GT -- he had to remove the intake manifold to get to the rear 3! The more I have looked at other cars, particularly ones of Asian design, the more I realize how VW specialized I have become. Looking at a Toyota Supra Turbo, for example, I almost felt the same way I did the first time I sat down in front of a UNIX computer -- completely out of my element.

In this new version, the music is, well, 'smoothed out' -- it's more consistant, but you lose a bit of the drama.

  13. RE: Ident through NAT on On the Definition of a Hostile Network Connection? · · Score: 3

    You have a good point about NAT and ident. Let me address one situation where I had to deal with this:
    • I set up an OpenBSD NAT box for a friend of mine, who happens to be an IRC (Undernet) junkie. Most (if not all) of the Undernet servers
    • require ident before completing a connection. I would have just forwarded the port 113 if his room-mate didn't want to do the same thing...

      but he did. Dammit.

      That left me searching for something to make IRC work through NAT, and I found the "Transparent IRC Proxy." It (optionally in conjunction with identd) handles ident requests, and returns a proper response based on entries in /var/run. These entries are quite simple -- they're just files named "user-n.n.n.n" and containing just the name to be returned for ident. Easy enough...

      It makes DCC work again, it enables ident to properly identify NAT'd users, and (as long as you find an Undernet server that allows more than one connection per host) it allows two people to be on at the same time. End of problem.

    To answer your question, ident certainly has value in a NAT environment. It can be a pain to implement (look into TIRCProxy, it does more than just IRC), but once established, it provides some accounting of who has done what. This can be the difference between pulling your hair out and simply plonking a user. I don't see this being much help in a business environment... but it certainly has recreational applications.

    NAT is a necessary evil right now. Hopefully, once IPv6 is in widespread use, ISPs will no longer be as stingy with the address space... and then it'll be a simple function of routing. Until then, I hope this helps.

I can't name another service that fills the niche that ident does -- I always thought of it as the internet's version of a BBS call-back. Everything else I know is on a case-by-case basis, and nowhere near as ubiquitous as ident is. That is ident's power.

    Also, current use is a far cry from the original intent of the daemon -- that's for sure. There was a time when an ident reply contained a valid email address. I know there are still some valid answers out there, but I know I've never taken an ident reply seriously. These days, either you get a reply (and the info is probably garbage), or you don't.

    You can thank the those windows users (like myself at times) for that. Heck, when I first started using IRC, I had no idea what ident was, and I didn't mess with mIRC's settings... thus, whatever you saw was nearly the same as ten thousand others, and even more useless.

    The fact that sysadmins now treat ident requests as 'attempted crack attempts' or (potentially) 'hostile network connections' says

I'm sure there's a "government recommended maximum civillian dosage," and it's set at a very harmless and generally un-reached number.

    Here's a little background on the Navy nuclear field:

    The enlisted and officer personnel that actually work on the naval reactor systems (ratings of MM, EM and ET, plus officer billets) go through a special school at Naval Weapons Station Charleston in South Carolina.

    • First, one is trained in their specific job duties. ("A School")

    • Second, you go through 'Power School' -- principles of nuclear physics, what makes these things work, how, and why they're dangerous.

      • While in Power School, you are scanned to determine exactly how much radiation you have absorbed thus far in your life. (Some call it "Hugging the Box.") From that, the Navy knows how much more exposure you can receive before you are no longer allowed near radioactive sources.

    • Third, you go to 'Prototype' where you get to play with a working reactor, just not on a working vessel. There are 3 of these in the US, 2 here at NWS Charleston, and 1 in Ballston Spa, NY.

    As far as exposure goes, I'm not going to get into the exact specifics & numbers. (I'm not sure exactly where 'common knowledge' stops and 'confidential information' starts.) Numbers don't matter in any case, as I don't have exposure readings for Petty Officer Hahn.

    The point is: The Navy has chosen a number for the amount of exposure you're allowed. David Hahn exceeded this number before he enlisted. Therefore the Navy will not allow him to work in a situation where he will receive artificial additional exposure. The Navy is not interested in medically retiring him and handing him a disability check because something turned cancerous, all because he went near a reactor... again.

    The Navy does understand the risks involved -- and they certainly minimize their exposure as much as they can, both to radiation risks and litigation risks!
