AI agentic workflows on large codebases
The first post went over some of its capabilities. Over the past week Edict went v1.0, adding cursors for reading projections after command dispatch (to close some eventual-consistency gaps), a new type of projection that holds state inside the Orleans grain directly instead of a table, saga timeouts, schedules, an improved skills package and MCP server that ships with Edict, and more. Edict has now grown to over 75,000 lines of code and more than 1000 tests, and contains several deep mechanisms that have been fixed, broken, and fixed again. It is well past the point where I can hold all of Edict in my head. This post is about working with AI on large codebases, which I expect to be the first problem most software engineers have to solve. The context problem Years ago I was talking to a PhD candidate whose area of research was Natural Language Processing (NLP). He explained to me that one of the most difficult NLP problems was context. If a colleague says they need to pop out to pick their kids up from school, a scene can form in your head: one with a school, the layout of the road, people waiting, walking, driving, the environs. You may never have seen the school your colleague mentioned, but you can form a rich scene from your accumulated experience and use it to drive the rest of the conversation with a shared understanding. LLMs ingeniously dodge this entire issue by making it your problem. Just a word-probability machine Strip away the chat window and a Large Language Model (LLM) is doing one thing: predicting the next token. Give it a run of text and it returns a probability distribution over what comes next, samples one, appends it, and repeats. Companies like OpenAI and Anthropic then beat it into shape using techniques like supervised fine-tuning and reinforcement learning, which tune those probabilities in meaningful ways. That is why Claude is always telling me "Good framing" or "You've spotted...". It even called me "Bold" on one occasion. The probabilit

Tech Pragmatism: Why More Decentralized Data Actually Equals Centralized Utility
Navigating the tech space today often feels like walking a tightrope between two extremes: massive corporate monopolies holding all the keys, and idealistic local projects trying to build everything from scratch. But this doesn't have to be an "Us vs. Corporations" battle. We don’t need to completely eliminate corporate tools; we need to leverage them. The real pragmatic goal is to use localized, decentralized data-driven systems to solve real-world physical problems on the ground, in real time. When people hear the word "decentralized," they often assume it means chaotic fragmentation, isolation, or losing control of data. It doesn't. Decentralization does not mean losing data; it means movement. In fact, the paradox of modern tech is that More Decentralized Data = Centralized Utility. 1. Moving Beyond "App Consumption" to Localized Edge Data For too long, the cultural conversation around tech has been stuck in the clouds. We talk about "the cloud" abstractly, and the average consumer's tech vocabulary is limited to a handful of corporate app names. True tech pragmatism brings data collection back down to earth, turning communities from passive consumers into active, node-operating contributors. Here is what that looks like in practice: Hyper-Local Climate Grids: Instead of teaching students about weather patterns using generic data from an airport weather station 50 miles away, a school can deploy its own low-cost local weather station. Students learn from their immediate microclimate, and that real-time local data is fed back into a wider community grid. Optimized Infrastructure: Instead of spending millions on speculative traffic studies, we can use existing, low-cost edge cameras to count traffic patterns locally. This decentralized edge data tells planners exactly what kind of infrastructure—like traffic lights (or "robots" as we call them here) or bypass lanes—a specific zone actually needs. It is planning based on true utility, not guesswork. The Energy Grid
