Storing hundreds of millions of simple key-value pairs in Redis
Really nice article and stats about key-value storing with redis:
When transitioning systems, sometimes you have to build a little scaffolding. At Instagram, we recently had to do just that: for legacy reasons, we need to keep around a mapping of about 300 million photos back to the user ID that created them, in order to know which shard to query (see more info…

Readme Driven Development @6Wunderkinder
During the last weeks, I have been interviewing possible engineer candidates. One of my questions is about the knowledge of readme driven development. Interestingly, not one candidate had ever heard anything about readme driven development, but nearly 90% could precisely explain what test-driven development means.

So I dedicate this (longer) blog post for a further insight into how readme driven development may be done under real-life conditions.
