  1. Systems Engineering on Getting Accurate Specifications for Software? · · Score: 4, Insightful

    Its called Systems Engineering and its a whole other profession. For a large, complex system like the ATC systems I work on syseng could easily account for 30% of your staff. Remember that getting the design right in the first place it the hardest part.

    The only way I can think of the convince the "sales" people who apparently run your site is to create a really big stuff up and document it in advance to make them culpable. The problem is that they will probably just get rid of you when they respond.

    You could try a kind of passive-agressive approach. Keep misunderstanding them. A bit like a monty python sketch. Don't go so far that they really get angry. Judge it so they come to their senses and start to write down exactly what they want.

    Isn't there an old adage: The user got exactly what they asked for but not what they want.

    I think you are screwed. Sorry. I have been in that situation before.

  4. Re:climb in suit? on Lunar Dustbusters · · Score: 2, Insightful

    I'm thinking they could insert their helmet into the air lock, and crawl out. That way, they'd only need to worry about dust that gathered on the helmet. But I suppose it would be expensive/impossible to design and make a one piece suit.

    They would need to bring samples, equipment, and suits into the habitat for research and maintenance. The dust is so abrasive that the outer surfaces of the suits wear away quickly and would need to be regularly replaced.

  5. Re:I don't see the problem. on Lunar Dustbusters · · Score: 3, Interesting

    Breathing hard vaccuum is a really bad idea, so most space suits likely to be worn will be 100% isolated from the outside. This means that the only possible place for dust to get into lungs would be in the landing capsule - if the helmets are removed. Let's say, however, that they are not. That the astronaut simply connects to a piped oxygen supply when in the capsule. Then the risk of contamination is greatly reduced. Not eliminated, but reduced.

    You should read the Apollo Lunar Surface Journal. Sleeping in the suits was found to be very uncomfortable, even for the short missions (Apollo 11-14). Even then they had to take their helmets off to eat and drink.

    Lunar dust is so fine it sticks to everything and gets into everything. Even Armstrong and Aldrin, who were only out for just over two hours, were absolutey covered with the stuff.

    The longer missions being planned for the future will need to have a proper airlock area where the crews can strip down to their skin, shower, and only then enter the living area. The airlock would also be used to maintain suit fabric and seals, which are the real problem IMO because the dust is so abrasive.

    Unfortunately the EULA that you never actually agree to until you install the software but is still enforceable because MS said so prevents students from reselling their discounted copies of Windows.

  11. Re:Fan and filter on a tennis racket on Astronaut Has 'Wasabi Spill' in Space · · Score: 4, Interesting

    I'm surprised they don't create a tennis racket-like device with a low-RPM multibladed fan and an accordian fine-mesh screen.

    They already have fans and filters, but it won't help if the wasabi is already sticking to something like a wall, some equipment, or a person. Cleaning up is an issue because water and cleaning materials are in short supply.

    It would be interesting to calculate the internal surface are of the ISS down to a reasonable scale. It must be several square kilometers, at least.

  12. Re:Not flimsy material. on NASA's Future Inflatable Lunar Base · · Score: 2, Insightful

    They actually provide much better protection from micro-meteorites and space junk then our current metal structures do.

    Crews of the long term missions (15..17) reported that the foam packing material which they left around on the surface started rocketing off into space (well, a couple of hundred metres, anyway) because it outgassed and then exploded.

    The problem with lightweight structures which have gas inside is that they make good rockets, not just because a rock might put a hole in it, but because a pressure regulator might open one day and create thrust. Pete Conrad joked about it happening to Al Bean and I have this (slightly funny) vision of a lunar surface crew watching their hab rocketing up into space because they used the wrong valve to vent an airlock.

    To me, this indicates that people who use AOL to search do not know the difference between a search box and a URL bar.

    I have set up systems for people who are very non-technical and they are exactly like that. They want one way to find stuff and having an alternate confuses them terribly. So I set their home page to google and tell them to search for what they want.

    TFA talks about the time of day that certain terms were searched for but doesn't say what timezone he is assuming the searchers are in. Most people assume you are talking about the USA these days, but even that covers four hours. But what about Europe? Even back in 1997 they must have accounted for a fair chunk of searches.

    What if they started "paying" (like 1 buck per somethingsomething) people for producing energy. they could store and resell it and some people would have a psychological incentive to excersise.

    I read once that prisons a couple of centuries ago would sell the energy generated by people doing "hard labour". The idea was that you would have to walk on something like a stairmaster for much of the day, which turns a shaft, which goes through the wall of the prison into the mill next door and does real work.

    The article doesn't hide this either, but there is really very little real energy to be won in this way

    You can get about 500 watts from a human body. If you actually get 200W per person and you have 20 people then thats 4000W which you can use to run lights, TV's, etc. Doesn't sound trivial to me.

    putting a generator on a bicycle that is capable of say charging a cell phone or a laptop battery. Perfect for people such as myself who commute by bicycle anyway. Would that be feasible? How much do you think it would cost to retrofit a bike to do that?

    You can still get generators for running lights at night, probably not much different from the one I had when I was very young, back in the 1970's.

    I have hydraulic disks on my commuting bike. Sometimes I want to just drag the brake slightly if I am waiting for a light to go green, etc. Something which inductively couples to the disc would be ideal for that.

    Well I have just bought my first ever Motorolla, after giving up on Nokia and Sony Ericsson due to bad hardware design. Yes the Moto is a bit kludgy, but I hardly use the UI. Its just a phone for me. It takes me back to the good old days of Ericsson phones. Remember the old HP RPN calculators, with the heavy buttons? They don't feel nice on the surface, but if you use one day in and day out you start to appreciate it. For me, the motorolla is like that.
