If you have used Memcached and have gotten carried away with how it can make everything faster, you may have felt some pain when that volatile memory disappeared into the ether due to a restart or a failure. Your house of cards comes tumbling down as suddenly nothing is in cache! Your application is scrambling around trying to fully serve your users and the database is screaming at the application, “what the *%$@ is going on up there?”. All your lack-of-performance implementation sins are exposed in one fell swoop and your boss stops inviting you to play golf. It’s tough, but a few hours later Memcached is singing again with a full belly of cache and your application layer is putting the kettle on to make your exhausted database a nice cuppa tea. You start to wonder… how can I persist this “caching” data?

The more people you help, the better. For instance, Facebook “helps” 250 million people per day, whereas Google only helps around 90 million people per day. Helping all those people has become very profitable for these two companies and many more. It’s all about changing the focus from “how do I make money” to “how do I help more people”.

In previous projects at MailChannels I have used Flot.js for graphing. There were many reasons I chose this originally. The graphs are interactive and can be manipulated within the browser without having to communicate back to the server.
