    The Difference Engine is nice, but is it programmable? Does inputting a set of initial values count as 'programming' ?

  2. For which value of 'code'? on What Is the Oldest Code Written Still Running? · · Score: 4, Informative

    The Science Museum has card decks for Jacquard looms that are more than a century old. Bletchley Park has a replica Colossus machine, which needs programming in the shape of switch positions. IDK if the code they use was preserved, or reverse engineered along with the rest of the machine, though.

    But I think they are 100% wrong to assume that the driving (being the "newer" skill) is the thing that suffers. I'd say that depends on the driver. Some people can cope (I tend to tune out the passengers when I'm driving), others I've seen not doing so well (driving erratically, almost missing turns etc.) in the same situation.

    In my experience, yes. Also, the amount of background noise makes a difference. Following a conversation inside a car while the radio is on is more difficult (to me) than having that conversation in a quiet room.
    Last year I visited some friends in the UK. English is my second language, and I've no trouble understanding any of them (various regional accents notwithstanding). But in a crowded restaurant, I found I could only understand half of what was being said.

    I do cook, on a gas range. Fridge is a small model (still, large enough to hold one week's worth of groceries), draws 70 W max. I don't use a laundromat, I run the washing machine about once a week. No dryer, a clothesline works fine. If I'm not in the room, the lights are off, so I rarely draw more than 30W for lighting.
    Otherwise, I don't know what to say. I'm not cheating/offloading to someone else, I haven't given up any comfort either.

    the average household in America uses around 11,000 kWh annually. I just about fell off my chair when I read that. My electric bill last year was about 10% of that. Now, I use gas instead of electricity for the big-ticket items (space and water heating, cooking), but still, the numbers quoted on the DOE website boggle the mind (2500 kWh for a fridge and freezer?).
  8. Re:not 135 MPG equivalent! on Tesla Motors Opens Retail Store · · Score: 1

    We need a price per mile measurement. Your own example proves that that would be useless. The cost varies too much over both place and time. Also, for plug-in hybrids, the cost varies wildly with the ratio between electric and generator-assisted driving.
    You need the fundamental information, so you can calculate the derivatives yourself.

    we need to quit letting these electric car makers get away with saying 135mpg. Now that I agree with. The figures used in another post ("40 miles electric, 50mpg after that") would be better, but one more parameter is needed: the number of kWh per charge cycle.
  9. Re:If that is true on How Water Forms in Interstellar Space at 10K · · Score: 3, Insightful

    So you can just will things into existence? Sorry, I assumed you knew the term. In this context, 'free will' is in opposition to 'predestination', the notion that God has planned our lives beforehand and we can't influence our own lives.

    If man were created without the possibility of sin, he wouldn't be truly free. He wouldn't have the choice of living within or without God's presence. Again, not very interesting for God.

    Why would God's sense of right and wrong be any more artificial than yours? And where does your sense of right and wrong come from? And how does your sense of right and wrong differ from the Biblical sense of right and wrong?
  10. Re:If that is true on How Water Forms in Interstellar Space at 10K · · Score: 0, Offtopic

    Someone who loved me wouldn't send me to eternal punishment for finite transgressions. That's not what hell is about. Ultimately, going to heaven or hell isn't decided by how much you've done right or wrong, it's decided by whether or not you recognize God as your saviour. You get to choose: be in God's presence (heaven) or be where He's not (hell). If you hate him so much, I expect you couldn't stand being around him for eternity.
    The only problem is that you get to make that choice only once, here on earth, with imperfect knowledge (which is why it's called 'faith', not 'science'). You can resent that, but here's a secret: there's a 'sure bet'. Live life as a Christian. If it turns out there's no God, you've lived a good life, the people around you will thank you for it, and you can go to dust in peace. If there is a God, you'll end up in heaven instead of the other place.

    An infinite and all powerful creator God can not desire anything, for being all powerful and infinite they have everything they could want before they want it. Rubbish. I'd expect that for an omnipotent God, creating beings that blindly obey him would be unbearably dull. God deliberately created us with free will.

  17. Re:Deprecated Warfighting on F-117A Stealth Fighter Retired · · Score: 4, Interesting

    Count on the F-22 having better radar stealth than the F-117. The F-117 fell victim to Moore's law: During its design, all the engineers were capable of simulating (for stealth characteristics) were flat panels, hence the faceted skin, which dictated the rest of the design.

    The size was another compromise (smaller = easier to hide), and the engines didn't have afterburners to minimise the IR signature, which meant no supersonic flight. Radar technology wasn't advanced enough to build a low-observable (or Low Probability of Intercept, LPI) air search radar, and a 1970's radar would compromise the aircraft's stealthiness even when turned off.

    Oddball maybe, but the F-117 was the best possible design with 1970s technology. To get it to work at all, everything else had to be sacrificed for the one mission that couldn't be done by any other platform: surprise attacks.

  21. Re:Do the words "Aegis Class Cruiser" ring any bel on Armed Robots Not Actually Gone From Iraq · · Score: 1

    Aegis needs some pretty large sensors (the SPY-1 radar), the smallest ships to use the system are ~5000 tons. To make full use of the system, you also need a decent missile battery.

    Aircraft carriers don't use Aegis. Carriers typically only have point defence weapons that don't need the capability of the Aegis system (which can track targets more than 100 km away).

  22. Re:Do the words "Aegis Class Cruiser" ring any bel on Armed Robots Not Actually Gone From Iraq · · Score: 4, Informative

    Sounds fishy to me.
    None of the ships involved in the initial Aegis tests can be described as "automated vessels". The initial radar tests were aboard USS Norton Sound, later tests would have been on USS Ticonderoga. Neither use Windows NT, and in neither ship was/is the Aegis system connected to the propulsion or navigation. Pulling the plug to the point where the ship was dead in the water wouldn't have been necessary on either.

    Also, there is no "Aegis Class Cruiser". The Ticonderoga class cruisers use the Aegis combat system, but so do several other ship classes (Arleigh Burke, some Japanese and Spanish ships as well).

    There was an incident where an experimental Windows-based ship management system (again, separate from the combat system) caused a Ticonderoga-class ship to lose propulsion.

    When usage starts peaking there is no way to get the sun to send down more energy. Yes you can. If you build your plant large enough to satisfy peak demand, throttling back is a matter of rotating or shrouding a few mirrors or PV panels. This will make the plant more expensive than a base load plant with fixed panels/mirrors, though.
    Also, with solar thermal, you can store surplus heat. Plus there's the nice coincidence that in warm climates energy usage tracks insolation (e.g. airco).
