SoundCloud Backstage Blog: If there is anything like a silver bullet for creating meaningful and actionable alerts with a high signal-to-noise ratio, it is alerting based on service-level objectives (SLOs). Fulfilling a well-defined SLO is the very definition of meeting your users’ expectations. Conversely, a certain level of service errors is OK as long as you stay within the SLO — in other words, if the SLO grants you an error budget. Burning through this error budget too quickly is the ultimate signal that some rectify...

SoundCloud Backstage Blog: There are many approaches to building libraries that wrap HTTP APIs. For many of our officially supported SDKs we chose to build light wrappers around HTTP client libraries with a few added features to make it easier to work with the SoundCloud API. This approach has a few benefits. It guarantees a certain consistency and is relatively easy to maintain. It’s also fairly future proof. Changes in the HTTP API do not typically require updates to client libraries. Sometimes however, you might be loo...

SoundCloud Backstage Blog: One of the SoundCloud API’s most powerful features is the timed comment. At its core it seems simple enough: a piece of text associated with a point in time for a particular track. But where you see timed opinions, I see a light-weight game scripting engine. So when Johannes Wagener told me he was adding an event to our JS SDK, I immediately began work on Wave Raid: Quest for the Timed Comment....

SoundCloud Backstage Blog: It’s no secret that SoundCloud is a Ruby shop, but that doesn’t stop us from giving some love to the Pythonistas in our community.
