  1. Re:The technology isn't that new on Refrigerators To Cool With Sound (Cool!) · · Score: 1

    Uh... 106 degree showers aren't all that uncommon, and it's not likely to scald. The recommendation is to run your hot water heater at 120 degress Farenheight, since above that will scald, and do so quickly (especially for young children), and any equipment that needs hotter water (like your dishwasher) will have a booster heater that's more efficient anyway.

    BTW, you'd need to expose some household bacteria to 160 deg. F to kill them... and I think we both know there's better ways to kill bacteria than squirting hot water all over the damn place :)

    Regarding the thermodynamics -- I certainly don't know thermo much at all, but I really doubt you could use the output of this to reliably heat water. Even if you're cooling the refrigerator by 40 degrees from ambiant, that's mostly air that you're cooling. Heating water takes a considerably larger amount of energy than cooling air does. But, as you point out, we are running the refrigerator far more often than our hot water, so as long as you have a tank based system you can still heat dump into the water.

    Except that ground water isn't 70 degrees -- it is often as little as 40 degrees. Even with perfect thermal transfer, that's just not going to output enough heat. It might work as a backup method, but not as a primary heat source.

    Of course, like I said, I know very little about thermo, so I could be wrong. Correct me if so, please.

    Well... kinda...

    I suspect some people do use alternate addressing, since Intel put it in the Xeon -- it has a (slower) 36-bit mode that can address up to 8 GB of virtual memory.

    The Hammer has a 48-bit virtual and 40-bit physical addressing -- not 64-bit, although there's a good bit of confusion on this (particularly since AMD's own docs refer to 64-bit addressing in some areas, but refer to the 40/48 bit addressing in others -- I doubt they implemented full 64-bit addressing; it'd be massive overkill for the lifetime of the CPU).

    I agree that Hammer is important for much more than address space though.

If you take that same system and it's 99.99% safe then you have one part malfunction every 100 uses. And since orbital systems are considerably more than 100 parts, you can pretty much guarantee that there's going to be a problem everytime, even at 99.999% reliability.

Most serious bugs aren't patchable by even above average programmers -- the time involved in learning the code base so you can figure out where the bug is and fix it is usually huge... hell, most programmers have a hard enough time fixing code they wrote 3 months ago, much less someone else's code!

    As a case in point, MS is still providing patches to Win98. Trying to find patches for a Linux system 4 years out of date is a daunting task. No, it's not true in every case. But the majority of cases it is true. It's stuff like this that makes CTOs break out in cold sweats when they think about moving to Linux. You can't simply upgrade to the latest version of library X everytime one comes out -- that kills support because they have to test everything before every upgrade to make sure nothing breaks.
