    Doctors offices do this quite frequently, they use a shared answering service for when their staff is too busy or not available. You might sit on hold some period of time before their phone system transfers you due to the high marginal cost of the outside service, it's not really all that different.

    To be more efficient and have better HA without paying crazy amounts to IBM/Oracle/MS for clustering. With modern virtualization like Xen or ESX 3.5 there's little penalty for virtualization if you do raw disk access.

    Then it's still over 75% more expensive to use electric then gas. Natural gas at the (US) national average of ~$1.15/therm is $12.37 per MBtu assuming modern 93% efficient furnace, electric at .073/KWhr is $21.68 per MBtu.

    Yep, HP and VMWare have a cool solution for this, your ESX cluster can grow automatically with machines that are powered off but brought to life through their lights out processor as resource usage increases or when you know you will need additional capacity. A solution I have seen is to move specific DB servers to their own host for nightly batch processing, it theory you could do the same with web and middleware servers to add to a cluster solution on the fly but I haven't personally seen that implemented.

    One easy tipoff is if it has a heatsink instead of a fan it's probably low power =) I have 4 fans total in my system, one 120mm intake, one 120mm exhaust, one 120mm in the PSU and one 80mm on the CPU. You can also check out review sites as graphics card reviews often feature power usage numbers (though that gives you relative performance in a test system rather than component level numbers alone). Integrated peripherals that don't tax the CPU excessively are also more power efficient than discrete addon cards so I went with a MB that had everything I wanted short of graphics and the tv tuner.

    Um, your computer is way underpowered or your IT department sucks because 15 minutes to boot in crazy. I have an old T42 with a 4200 rpm HDD and it only takes about 5 minutes to boot and that's with multiple server type services installed (I have two copies of MSDE installed if that tells you anything). Also Citrix logon times at my shop are ~90 seconds average and they will be more like 30 once I get the users profiles onto a faster file server.

    How about build an energy efficient PC! I have a LP AMD 64 x2 with a Geforce 7600GS, 2 HDD's, 2GB of ram and a TV tuner and an 85% efficient PSU and I peak at around 150W, using 140W at idle is insane. For the next generation of games I'm thinking about upgrading to a 9600 GSO but that will up my idle and peak numbers by at 20W so I'm holding off till I get a game that really needs it.

  9. Re:Efficiency on Plug-In Hybrids Aren't Coming, They're Here · · Score: 1

    Those CARS aren't 40-50% efficient, if you look at thermal efficiency they are more like 7-8% efficient. A diesel-electric locomotive is ~30% thermally efficient which is about as good a fossil fuel systems get (one large ship diesel engine achieves 50% thermal efficiency but I can't find numbers for system efficiency since it probably depends on cargo load).

    Huh? Both the 2009 ZR1 and 2008 Z06 are available in the UK, perhaps your local dealership doesn't have one but they are for sale in the UK from what I can find on the net. Both are outfitted with their US engines.

    You're on crack. The 750i (new F01) is 407hp@5500-6400, the stock C6 is 430hp@5900 so yeah I would say the C6 is completely comparable to the 750i. Price wise you can get a Z06 for about what a 750i costs and that does 505hp@6300. The standard C6 gets 16/26 mileage vs 17/25 for the 750i, so I'd call it a draw. At the high end compare the ZR1 with a 650HP 6.2L engine to the 760i with a paltry 438HP from a 6.0L engine!

    I often wonder why Toyota pulled the plugin capabilities from the Prius, the hardware is there in the first generation models, my friend has a kit to convert his once the battery warranty is up and there's not a lot to it, just a plug that attaches to some internal terminals and a chip mod to delay the engine warm-up until the battery is much further drained.

    In the mountains storms can come up with VERY limited warning, ask any mountain climber!

    The dude was a multi-millionaire, him having $1K in cash on him isn't in the least bit unusual. Also the plane crashing into the mountain might be pilot error (likely), but it could also have been weather or mechanical problems. It's impossible to be sure until the investigation is complete, and perhaps not even then.

    Most celebrated distilleries that do blends try very hard to maintain consistency in the taste and so all years bottlings should be very similar. I know a similar show I watched showed a distillery where they kept a bunch of ~100 year old samples around as a reference so they could maintain their classic taste.
