The blog post explores the software development lifecycle (SDLC) with a focus on the development stage, particularly highlighting DevZero's approach to projects as a combination of source code and the environments they run in. It describes the engineering process, starting from initial proof of concepts to the design and coding stages, and discusses the diversity in development environments, such as local computers, cloud-hosted virtual machines, and docker containers. The choice of programming languages and frameworks is influenced by company culture, with a recent trend towards containerization and strongly-typed languages like Java, Go, and C#. The post also emphasizes the significance of internal frameworks, project structuring, and tooling like Buck and Bazel. It suggests that future development may increasingly shift to browser-based environments, aiming for faster, cheaper, and more efficient setups. The discussion includes insights into the challenges and potential of evolving development environments, emphasizing the need for environments that are both disposable and tailored to specific projects.
