Playing God with CERNs LHC

“No, playing God is to create a bunch of people in a magic garden with a talking snake, then tell them not to eat an apple because… just because… then punish them mercilessly for all eternity with painful childbirth and talking (oops! No more talking) snakes striking at their heels, murdering them all (except 8) in a global flood, waiting until they grow up another population again (twice through incest) and then impregnating a virgin with yourself, then sacrificing yourself to yourself to spare your own creation from your own wrath.”

SATA vs. SCSI reliability

“Here’s a guy who discusses SATA
vs. SCSI disk reliability. Short conclusion: actual disk failures (MTBF) are almost exactly as likely wtih cheap SATA disks as expensive SCSI disks. But the bit error rate of SATA is much higher. In other words, the likelihood of not being able to read a sector because it got corrupted on SATA is vastly higher than SCSI. By his calculation, on a 1TB disk, you have about a 56% chance of not being able to read every single sector, which means rebuilding your RAID correctly in the case of a failed disk is usually impossible…. “
