Teams reach for it as a spam filter, a phishing filter, and a general trust signal. It is none of those. The current DMARC protocol, defined in RFC 9989, answers a deliberately narrow question: did the owner of the domain in the visible From address authorise this message, and can that authorisation be established through an aligned SPF or DKIM result? That question is worth answering. It is also much…

Incrementalization inside the framework means that values don’t get recomputed until necessary. This applies to every value, not just the view. Other web frameworks tend to lump together state, incrementality, and rendering into a single abstraction, the UI component. By contrast, Bonsai allows you to compose state…

I mean, I've done this. But I've been on the receiving end too many times now. This is not adding value. I can talk to Claude myself. It's going to be faster and I get to control the context. I don't need a meat proxy in between.…

🚀 Explore this awesome post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: The intuitive notions of computation and algorithm are central to mathematics. Roughly speaking, an algorithm is an explicit, step-by-step procedure for answering some question or solving some problem. An algorithm provides routine mechanical instructions dictating how to proceed at each step. Obeying the instructions requires no special ingenuity or creativity. For example, the familiar grade-school algorithms describe how to compute addition, multiplication, and division. Until the early twentieth century, mathematicians relied upon informal notions of computation and algorithm without attempting anything like a formal analysis.…

OSM gave the project a useful starting point, with thousands of public bookcases already mapped around the world. Book Corners also accepts new libraries directly from its users. People can submit a location and a photo, and the contribution becomes public after moderation. It seemed only fair that, when one of those submissions was missing from OSM, Book Corners should be able to…
