Extreme Linux Server Available to North America 188
jcasman writes "CNet is covering an announcement from Japanese Linux provider Plat'Home on a low-cost, super tough Linux-based server, now available in the US, that can handle extreme heat and cold. 'The OpenMicroServer is kind of an "extreme" use server pushing the boundaries for normal, low-cost hardware. In a 624-day endurance test, the OpenMicroServer performed normally under 122 degree F conditions. The unit also employs a power efficient AMD Alchemy (MIPS) CPU and precise part placement based on thermo-fluid analysis to achieve semi-hermetic construction.'"

In practical terms nothing.
In technical terms 'centigrade' scale is defined as having zero at the melting point of ice, and 100 at the boiling point of water at standard atomopheric pressure. While celsius is defined as the kelvin temperature - 273.15.
The reason for the difference was that the melting point of water is hard to measure precisely, due to the mechanics of melting creating an insulating layer of meltwater around the ice, that you can't simply stir to remove because that would introduce heat...which obviously is counter productive.
So they redefined it in terms of Kelvin which could be measured more precisely, and renamed it to make it unambiguous which definition was being used.
And where does "stat" come from when used in medical dramas?
stat is from the latin 'statim', which just means 'immediately' or 'at once'.

Plus, Kelvin is itself based on the triple-point of water so we can't say that Celsius is based on water and centigrade isn't. They're really just synonyms.

In kelvin's case it is:
0 K is at absolute 0
273.16 K is at the triple point [wikipedia.org] of water
Celius is defined with the same two points, as -273.15 C and 0.01 C. This definition makes the freezing point of water approx. 0 C and the boiling point approx. 99.9839 C [wikipedia.org]
Some of the above may have been shamelessly ripped from Wikipedia. "Degrees" character removed because Slashdot mangles it into "Â".

Completely incorrect. The meltwater will be handily at zero celcius until all of the ice has melted - it's a nice simple example of how the temperature remains constant until you get the energy required to change phase. Zero is that point precisely because it is an easily acheived stable and known temperature. One hundred

It should be possible to start most computer systems right down to a few degrees K. The main risk is that something will break through differential expansion as it heats up. I would easily believe that a COTS PC could be started at -100C, but would stabilise above 0 C once it had been working for a while.

An extreme end server that is ruggedized against severe temperatures has potential value in a number of areas. First, it certainly meets the thermal requirements for military-grade systems, so I would expect to see this getting some interested looks from that direction. Severe temperatures have killed voting machines, so that's another place that might be very interested in this server. Commodity e-voting with far more reliable hardware will sound a LOT more atractive to many States. The range isn't extreme enough to support some of the really harsh environments out there, but it would be good enough to get a tracked vehicle with a hose attachment into places too hot and too dangerous for human firefighters who wouldn't be able to stay that close to a fire.
