This is the first in a multi-part series, “Brittle Clojure”. In this series, we will consider common patterns in Clojure which yield brittle systems, as well as methods to ensure robustness. None of the basic principles for building robust software are unique. Most literature, however, is focused on object-oriented systems. Our point of view will sometimes zoom in to Clojure “in the small”, and sometimes zoom out to distributed systems built with Clojure. ...

Among DORA’s more controversial findings is that trunk based development is superior to feature branching. Teams achieve higher levels of software delivery and operational performance (delivery speed, stability, and availability) if they follow these practices: Have three or fewer active branches in the application’s code repository. Merge branches to trunk at least once a day. Don’t have code freezes and don’t have integration phases. Since we know not to be Cremoninis, we won’t be distracted by whether trunk-based development meets the HN trendiness standard, and we’ll be skeptical of anectdotal appeals to experience ...
