Part 1 developed a driving metaphor for GenAI-based development: you are the driver, the coding agent and its harness are the car, and your code and delivery system are the road.And in the same way that the road determines how fast you can drive, the...
Enterprises can self-host, sure. Open source projects uses it for the the network effects of GitHub. But why does a small software team need to use GitHub?I understand the ecosystem argument. Once you've got your repos, CI/CD, PRs, code rev...
Teams building AI agents on AWS often face a fragmented data architecture: operational data lives in Amazon DynamoDB while vector embeddings for semantic search sit in a separate, purpose-built vector store. This duplication increases infrastructure...
