comment Guaranteeing ACID properties for InnoDB databases
Good point about battery-backed write caches. I should have said "disable any non-durable write back caches".

comment High %idle on EC2 instances despite high load
For the purposes of this discussion, let's say I'm running a render farm. My workload is CPU bound, and I'd like to pay for exactly as many CPU hours as I'll actually use. Any time spent idling is paying for CPU that I'm not using. Because my load isn't variable (like e.g. web serving), I don't have to worry about having excess capacity/slack to handle workload spikes. In reality, I don't mind the load being somewhat less than 100%, but in our experience it can be as low as 80-90%. I created the particular toy problem above just for demonstration purposes.

comment Force SSH to use a specific shell
Good stuff. That graphic on the O'Reilly page is very nice. In my particular case, however, I want to be able to force this for any users, not just users who have set up their keys correctly. I also don't have root on the server machines, so I can't edit files like /etc/sshrc.

This is what I eventually did, but using scp. A great idea.
