Ten Most Wanted Design Bugs

RAID 1 saved my life last night. On a related note, on the list of the Ten Most Wanted Design Bugs, the #1 computer design bug is “No safety from power failure”. This goes beyond UPSs. All modern power supplies should have 45 seconds of reserve and be able to signal the OS – all modern operating systems should receive that signal and immediately be able to suspend or shut down. Currently power supplies don’t because it would add $25-$50 to the system cost. Windows & OS X might be able to do it, but Linux has difficulty hibernating (although not shutting down) because BIOS & chipset manufacturers do not release enough information.
