Based on their experience with arbitrarily shutting down servers or simulating the shutdown of an entire data center in production, Netflix has proposed a number of principles of chaos engineering.
Twitter has open sourced Diffy, an automated testing tool used in production for discovering potential bugs in new code running on Apache Trift and other HTTP-based services.
Remembering that automation is a side benefit and not the reason for BDD is one improvement to more closely follow the recommendations of BDD thought leaders, Joe Colantonio explains noticing six ways of improving work with a BDD mindset.

Hans van Wezep, software architect at Philips Healthcare, talked about model-based migration at the Bits&Chips Software Engineering conference. InfoQ did an interview with van Wezep about the challenges in maintaining legacy software, why manual refactoring is error prone, using models to refactor and migrate a codebase, and the benefits of using models when maintaining legacy software.
Continuous Integration can help to find integration issues earlier and to visualize the status of the build to all involved. Integration problems can be detected at build-time in stead of run-time during testing and teams can get immediate feedback on changes that they made and on the impact on components that are developed by other teams.
Oftentimes, complex software projects span across multiple repositories on account of external dependencies. This can be a challenge in itself, explains Google WebRTC engineer Patrik Höglund, who also described Google's approach to developing software that uses dozens of third-party libraries such as Chrome.
An interview with Yaniv Yehuda, Co-Founder and CTO of DBmaestro, about how they are doing agile development and using DevOps, how they implemented continuous delivery, on agile practices that turned out to be difficult to implement, and the benefits that they are getting for using agile and DevOps practices.
At Unruly teams have been applying eXtreme Programming (XP) since being founded in 2006. Teams take a test-first approach to developing code and invest in automated checks that can be run in live environments. InfoQ interviewed Rachel Davies about the importance of a continuous approach to testing, how this has evolved over the years and the business advantage that it delivers to Unruly.
Behavior driven development (BDD) can be used to improve communication between testers, developers and the business. For example you can use given-when-then scenarios to develop test scripts and at the same time define the requirements of the system. BDD involves all team members and helps them to think about the product.
Google has open sourced Jsonnet, a configuration language that supersedes JSON and adds new features without breaking backwards compatibility: comments, references, arithmetic and conditional operators, array and object comprehension, imports, functions, local variables, inheritance and others. Jsonnet programs are translated to compliant JSON data formats.
