comment How many users are “many users”?
right - that's what I had in mind: Make sure that the database doesn't have to touch the disk on read. Regarding swapping: You don't want any swapping to happen if you optimize for high load. Might as well disable swapping to come to a hard stop instead of degrading performance when memory is exhausted.

comment mod_rewrite redirect from SSL to HTTP not working
+1 for the answer: I've seen way too many problems with mixed setups. You will find holes. They will be unexpected. No matter how many you've already plugged - seriously.

comment created pub/priv keys using putty, created .ssh folder and authorized_keys, still not working
This is the issue I've most frequently been bitten by after learning that Putty and OpenSSH use different formats for their key files.

comment Picking up the pieces after missing Linux admin
fully agreed, but as the system is already live, I guess there's no way around learning on a live system.

comment I need to rewrite https://domain.com => https://www.domain.com because of wildcard SSL
Also, you might be able to get both, the wildcard and the toplevel domain in just one certificate - see the answers to serverfault.com/questions/87005/…. I've not tried that, but this way you could work with just one certificate (and on the same IP address) instead of requiring an extra IP address just for the top level address.

comment I need to rewrite https://domain.com => https://www.domain.com because of wildcard SSL
One could argue that it's rather "fortunate" that the client checks itself, not unfortunate. If the redirect could happen prior to SSL negotiation, traffic would obviously not be encrypted and a man in the middle could redirect the client anywhere they want to. This extra certificate usually costs money, which is unfortunate :)

comment Prevent direct call of a file
Great example. There's no 100% solution, but this comes as close as it gets, as the referer header is not mandatory and would be easy to tweak, though not in situations mentioned in the question. +1

comment Ubuntu 9.10 cron script 'ec2-consistent-snapshot' unable to execute and access files
with PATH being set to /home/ubuntu: Is your .awssecret located in /home/ubuntu or in /root? I believe it should be in /root when you execute this way as root. You could also define HOME the same way as you do SHELL or PATH - I didn't mention this earlier
