Autonomous teams are an article of faith in modern software development. The shape of our value determines what we can do; it determines our trade-offs between agency and coherence. We all have a purpose, and we all have agency to do something, hence the suggestion is moving from product focus to value center thinking.

Article: When Spec-Driven Development Pays Off

AI coding assistants have become a core part of software development. AI-generated code has shown productivity gains, but it's also contributing to security weaknesses and familiar bug patterns. In this article, author Nitin Garg highlights the bottleneck has moved from code generation to code verification, and how to detect & mitigate it when the AI-generated behavior diverges from the intent.

IETF Publishes RFC 10008, Adding the QUERY Method for Safe Requests With a Body

In June 2026, the IETF published RFC 10008, introducing the QUERY method to HTTP, the first new standard HTTP verb since 2010. QUERY enables developers to send richer query filters in the request body while maintaining cacheable, safe, and idempotent semantics. This addition addresses long-standing limitations with GET and POST methods, facilitating improved API interactions.
