   Project mention: A year of AI-agent incidents. The model is rarely the bug. | dev.to | 2026-06-19

   n8n issue #25276 documented that after the v2.4.7 → v2.6.3 upgrade, the platform's Vector Store Question Answer tool began generating function-call schemas that both OpenAI and Anthropic rejected outright. OpenAI returned Invalid schema for function 'protocol_knowledge': schema must be a JSON Schema of 'type: "object"', got 'type: "None"'. Anthropic returned tools.0.custom.input_schema.type: Field required. Workflows that had run for months started failing on every call.

   Project mention: What job interviews taught me about Kubernetes | news.ycombinator.com | 2026-06-15

   I don't think you can provide all the features of Kubernetes while reducing the complexity. What is possible is to support a subset of the features of Kubernetes while making it easy to use.

   https://github.com/openrundev/openrun is a project I am building. It supports declarative deployments, on a single-node with Docker or onto Kubernetes. The target use cases is limited to standalone web app, like internal tools. No support for stateful services, you manage stateful services yourself. With that simplification, OpenRun provides a much easier developer experience.
