Microsoft cargo cults memcached! , via Simon Willison.
Back when I worked in a semi-.NET shop, we needed to cache some pretty expensive operations somewhere. In memory would have been ideal, but we had no way to coordinate between application servers. It ended up going in the database, because that made everyone feel safe. In hindsight, it probably wasn’t the greatest idea.
Long story short, my internal clock that tells me how long it will take Microsoft to clone a forehead-slappingly-obvious-idea is well set.
