I run my multiple servers in RAID. "failing before you realize it" - mdadm --monitor immediately reports that. I haven't yet faced the second failure of degraded array. Besides RAID6 I guess only a few blocks would get lost, the drives do not disappear completely from my experience.
Due to the licensing terms LibreOffice can import code from OpenOffice.org but not the opposite way. For the opposite way they need to fake it somehow like pretend a clean room reimplementation or so. I do not know what happens in reality.
On my 16-core (not counting HT) Haswell my C++ application builds 80 seconds. And rebuilding patched GCC + running its testsuite I do not wait for as it takes an hour or so. I discarded my box from 2005 after calculating that in a few months I would pay more on electricity than what is worth a new hardware. BTW I haven't played games for about 20 years. But sure for text files editing a 2005 box may be fine.
