As part of our continuous effort toward making improvements to our API with the hope that we can relaunch API access to all developers, we’re making some critical security improvements. Please note that these are important and time sensitive and may cause disruptions in your app if you don’t make the necessary security upgrades.

Let's take a look at techniques we can use to confidently release updates to an internal library that's integrated into hundreds of projects across the company — even if they're API-breaking changes.

In a product company, changes are inevitable so as to best support the strategy and the vision. Often during such a change, new teams are formed and other ones are restructured. While there are many challenges to be solved during a big change, there’s one in particular that’s often overlooked: system ownership. Having experienced not-so-successful handovers, I was inspired to create a guideline that will help other teams do handovers differently.

• Dependency Injection
• Dependency Inversion

As our codebase scales, the need for cleaner architecture becomes more apparent. The dependency inversion principle (DIP) is one tool that helps us build cleaner relationships among our software modules. In this post, DIP is presented using atomic modules and is later applied to frameworks.

We take software testing very seriously at SoundCloud. As we scale our codebases and vary the testing harness, we've also faced some challenges with maintainability. Take a look at this post to learn about some of the tooling we've built to help us manage the execution of and derive insights from the dozens of thousands of tests every day.

Sometimes keeping your team up to date both weekly and candidly, without adding extra meetings and friction to your workday, is difficult. If only there were a newsletter they could subscribe to to keep updated…
