Hi All,
If Curiosity is running Windows There doomed.
All you'll see on the live feeds will be the BSOD or 'your computer will be rebooted in 15,14,13,12 ."

why is it that invariably some moron feels the need to bring something like this up ?
Serious embedded systems do not run Windows as a core os. Neither do they run botched-together and endlessly forked contraptions like linux.
Serious embedded operating systems are timing accurate , fully deterministic systems like VxWorks, pSos, Nucleus or iRMX and run on rugged, hardened hardware with erro correcting memory. It is extremely hard to make a system like iRMX go tits up... We have several pieces of equipment (Eaton Ion Implanters) that run this Os. I have seen catastrophical hardware failures that wuold bring any other os to its knees. iRMX trapped the hardware failure, recovered and kept going. One such event was a failed stick of DDR memory. iRMX paused for a few seconds , interrogated the memory controller and found parity errors in a whole bank of memory. It marked the affected address blocks as 'bad' ( like it would mark a drive sector bad ) , found out what was loaded there , reloaded that from disk , and then kept going. The machine did not shut down or lock up. A log entry was made that addresses x to y were bad and should not be used with a notification that on the next planned shutdown the memory should be replaced. a couple of days later the machine scheduled for planned takedown and maintenance and that's when we replaced the failed dimm.
Any single bit error in any other operating system would have catastrophical consequences. not in iRMX. it simply shrugs , and moves on
