Mondrian at Google

Python's inventor Guido van Rossum is at Google. His first project was a tool for code reviews called Mondrian. Described here and in a video.

This is a revealing glimpse of a 21st-century software development organization.

• Heavy use of tools to automate the organization's own development process.
• Social not silos. Developers can view other developer's Mondrian dashboard. The tool is an enabler, not a rule enforcer. The review process itself builds relationships between senior and junior staff.
• Save everything. Mondrian saves every reviewed source file and all comments. Great for resolving customer problems months later. Also great for tracking metrics.
  

Other notes

• data encrypted on HD so when throw out server no privacies worries
• Google uses perforce (p4) but no developer branches! Means code reviews must work with files on dev machines. They use NFS so anyone can browse anyone else's machine
• runs on one box! in python
• uses Google BigTable
