comment 3rd party RAM for Mac Book Pro
At least all the local mac shops (haven't tried the Apple store yet) fully expect to see non-apple ram and conveniently ignore it... After all they all sell kingston ram to all their customers in the first place.

comment Really poor performance with 10Gbit Ethernet on custom app
If fragmenting is happening, performance invariably goes down the drain. The router (or switch) doing the fragmenting just doesn't have the CPU to do it fast. I think Keith got it bang on.

comment Is it possible to make a programme not occupy more than 50% of CPU?
Sure... "nice -n <priority> <program>" where priority goes from "-20" for very high, "0" for normal and "20" for lowest possible. If the hypothetical program was called "server", and low (but not lowest) priority was desired, this would work: nice 10 server

comment kernel: journal commit I/O error
True. But in an install or early boot situation, the bulk the memory usage is the buffer-cache so the problems tend to appear there first. Once the machine's been running some load for a while user process dominate memory I/O and so the segfault's prevalence. That being said, a PE1950 should have Xeon processors and ECC ram so the RAM should be able to detect it and report it to Linux.

comment How do I differentiate “fake RAID” from real RAID?
From personal experience, Areca cards might be real RAID... But any card that can crash and require a server powercycle to reboot (not a soft reboot) is mighty annoying. They were also highly temperature sensitive. A 5-10 degree rise in computer room temperature (like when transferring to city water supply on the A/Cs) will crash them... Requiring a hard reboot.

comment Suggestions for entries in a sysadmins .vimrc
Generally agree with this... But a tab is 8-spaces. Anything else and it behaves differently in vim then in less/tail/cat. Might be one of those religious things though.
