Quoted: We do very little to encourage people to understand the properties of their algorithms before they start coding. Generally this is a much bigger problem than any machine level anomalies you might encounter. The “real costs” people need to know are more often at a much higher level than the machine.

Bloom filters have been extremely useful in a number of problems I've worked on; I haven't watched this yet but I'm sure there are some interesting nuggets.

Quoted: If your six nines system goes down mysteriously just once and it takes you an hour to figure out the cause and fix it, well, you've just blown your downtime budget for the next century. Even the most notoriously reliable systems, like AT&T's long distance service, have had long outages (six hours in 1991) which put them at a rather embarrassing three nines ... and AT&T's long distance service is considered "carrier grade," the gold standard for uptime.

Quoted: Many people think of Operations as "a bunch of boring work... which I'm hoping someone else is doing." It often takes less time to set up a development environment than the tools and infrastructure needed to test, deploy, monitor, and scale new software. The survival of most projects depend on working software, at least initially, and so if there is money or time many people will spend it on development. Unfortunately, people say they will "figure that ops stuff out soon", but what they mean is "when we're totally screwed!!!" It doesn't have to be that way...
