I really appreciated John Nunemaker’s recent post about the way they’re using Kestrel (a distributed message queue) in Gauges.
There’s nothing revolutionary in the way that Kestrel’s being used here, from the post it seems to be a fairly standard use case for it, but it’s a lovely example of detailing the day-to-day work of growing a web app that blogs are so good for. And it’s particularly good to read about the stages they went through as they tested each component in turn, in production, before switching over to them completely.
