When people learn that I work as an open source evangelist (focusing on syslog-ng and sudo), they often ask me what it's like to represent such well-known names in the Linux world. My short answer: It's good! I am part of research and development, so it is never boring. I feel that I make an impact when people implement what they learn from me and when the feedback I collect from users influences the development of the product.

What if the software works fine most of the time but causes bugs in certain circumstances?

It is extremely infeasible to keep hitting the database for resources that have just recently been fetched. This is where HTTP or HTTPS comes in with a solution called caching.
