  1. ... And there are common differences between "'Murrican" and "Euro"
    technologies that often have cause to shift back and forth.

    The new plumbing one I heard about on the weekend was the notion of
    putting water heaters and thermostats at the level of the water tap.
    This is apparently pretty common in Europe; heating the water
    dynamically, at the destination. On our side of the pond, it is more
    typical for there to be a boiler somewhere central, with two pipes
    going to many locations. There are some merits and demerits to each

    Yep, was getting annoying to carry all those car batteries into
    the living room, just to power my PC.
    One of the reasons you won't see this home automation stuff over
    here, is the fact that houses are generally build rock solid over
    here. For sure you won't get a building license, for typical?
    American houses as seen on TV, made out of wood. Once saw how one
    of those is made quickly with a staple gun out of thin laths!

    Looked like a joke to me and I didn't wonder after wards that
    there's almost nothing left from these after the first

    For sure those are much cheaper to build and enough for most
    purposes, but not what we expect. On the other hand it's a matter
    of fact that none in the world has such an high per habitant
    usage of energy like the USA. One reason might be related to
    this way of building houses, another that most US cars seem to
    guzzle fuel.

    Another might be the fact that a larger percentage of people
    doesn't live in there own houses here, just look at a map, how
    small Germany is and how many people live here. It's slightly
    smaller then Montana, with a little over 80 millions habitants.

    We don't have that much surface, thus a plot of land is pretty
    From Christopher's post I got that this "home automation" is just
    a hobby for technical interested people. While it sounded from
    others, that this is a must have in any building in the USA.

    Strangely enough, I know quite a lot about these, having lots of X10
    stuff around, and having written a driver once. I don't use it
    seriously, however.

  4. Ahh...but the truly absurd comes from these fancy new lighting control
    systems where you can program them to turn on sets of lights and adjust
    dimmers on them all, etc., all at the touch of a single button. "Home
    automation" (at least the lighting part) taken to the extreme where you
    need a full day class just to learn how to turn on the lights in the
    kitchen. Pity the poor guest in such a house who can't turn on a single
    light for lack of a simple lightswitch! (Just the other day I saw
    somebody on TV having to study a control panel about 1 foot square to
    locate the right button to turn on the lights in the next room. Her
    first attempt turned out the lights on the other side of the house. Now
    there's a technology we all should have.)

    I think I'd better stop ranting now.... ;)

  6. Technology to the rescue. "Scene Control" used to require extensive
    programming. Fortunately you can install a "learning program" or even a
    device that "learns". Set the "mood" lighting or "panic" lighting or
    whatever using the technique that Michael uses -- specifically going
    around from switch to switch. When everything's just the way you want
    it you tell the learning switch or scene controller to remember all the

    Pity the poor guest in such a house who can't turn on a single
    This won't happen in most realistic cases. In the early days of home
    automation there were some famous nightmare cases --- akin to the B
    movie classic about vehicles that developed a mind of their own and
    turned on the humans -- in which home automation systems began to do
    crazy things on their own initiative. To the best of my knowledge
    almost all the hardware made in the past few years can allow switches to
    OVERRIDE controller settings.

    Of course, I suppose nightmares are still possible if the system
    designer fails to install switches in an intuitive order. To
    illustrate, the first switch in a n-gang panel ought to turn the lights
    on or off in a given room -- not the nth switch.

    (Just the other day I saw
    Kinda like KDE looks to people who grew up with Borne shells? Or for
    that matter it's kinda like simple unix commands back in the early days
    of commercial unix applications. rm *.* Or, going back a few hundred
    years kinda like angry "common folk" who visited yarn spinning factories
    in angry mobs because they couldn't cope with the social and technical
    complexities of change. Get used to it! :)

    Some servers have built-in devices to allow for full remote administration.
    The Dell Poweredges that we use have a RAC (remote access controller) that
    allows for full administrative access using a web browser. It runs its own
    SSL web server, and allows you to look at logs, temperature, fan status,
    disk status, and even see and interact with the console. You can access the
    BIOS and the operating system while it's loading, so you can react to
    hardware problems if you have to. You can even power cycle it. Our 1750
    that came with it was only $2500(US), and our 2650 was a little bit more than
