Why We Killed Our End-to-End Test Suite - Building Nubank
When you're building a large system, what you're really building is a high-speed testing and logging system, not the actual architecture itself. Sure wish more people knew this instead of continuing to do it ass-backwards. There's a zillion kinds of testing, but testing is how the org learns, and a fast learning loop has to come ahead of any other consideration (although that loop first exists at the business layer) Here's a random blog essay

Testing architectures are hard. Let's go shopping! Testing architecture issues are a leading indicator of many, many other kinds of architecture issues. |

My new buzz term for the week, "Autonoeic Consciousness", which is the brain's ability to time travel and theorize about how other brains, and itself, might act based on future events or past counterfactuals |
Why Science Can't Settle Political Disputes
Taylorism, and its many failures in both political life and industry) is probably the best example of how a physics-based scientific mentality about managing things in the real world seems obvious but is deeply flawed. It's not that it's always wrong. It's that it is intuitively obvious and works until it catastropically fails. It's important to know why

For any sort of technical/nerdish discussion, the most important thing to do is set up boundaries or guardrails before you wander all over the place. People forget the diamtetric opposite nature of science and politics, and it's hurting both fields |

How Big Tech Runs Tech Projects and the Curious Absence of Scrum
Dear Scrum Butt-heads, you can't be dogmatically non-dogmatic. Learn more why and less how, then some of this will make a lot more sense. During the online discussion, there was a great reference to the McNamarra Fallacy

Much of interest here. I esp like him bringing up WhatsAp. A good architecture can lead to a small, nimble team that delivers, and vice-versa. Architecture is the only way you can aggressively limit the number of people involved, and that's a requirement for running fast |
Offline First
HN Discussion on Offline First. Some readers complain they still haven't found the holy architecture for offline first, which to them means replicating the entire backend on the client. No doubt. Lotsa hidden assumptions in the way hackers talk about this. I love the SQLite/S3/Lambda comment by smackeyacky
