In the first article of this series, we saw how a custom build-time compiler can transform a legacy Angular.js template into raw, optimized JavaScript. To recap, starting from this template: <!-- simple.html --> <p> Hello {{ name }}! </p> Our Go compiler generates the following JavaScript module: // simple.js export function template () { const p_0 = document . createElement ( " p " ); const text_1 = document . createTextNode ( "" ); p_0 . append ( text_1 ); return { mount ( container ) { container . append ( p_0 ); }, update ( change ) { if ( " name " in change ) { text_1 . data = " Hello " + change . name + " ! " ; } } } } This is incredibly clean. By running template() , we get an object with mount and update methods. Using mount is fully intuitive: we pass a reference to a DOM element, and it injects our empty paragraph ( p_0 ) into it: import { template } from ' ./simple.js ' ; const { mount , update } = template (); const container = document . getElementById ( ' view-container ' ); mount ( container ); // The DOM now contains: <p></p> (waiting for data) However, the paragraph remains empty until we call update with a change object like this: let changes = { name : " Mario " , }; update ( changes ); // The DOM surgically updates to: <p>Hello Mario!</p> But who is responsible for tracking changes in our application state, building this changes object, and calling update ? The answer lies in marrying the legacy Angular.js $scope with the modern JavaScript Proxy API . The Legacy State Pattern In a traditional Angular.js application, developers mutate the state directly inside a controller by assigning properties to the $scope object: // simple-controller.js export function SimpleController ( $scope ) { $scope . name = " Mario " ; } To bridge the gap between this legacy controller and our new build-time template, we need a way to automatically capture the assignment $scope.name = "Mario" and translate it into a structured update: let changes = { name : " Mario " }

I want to share some thoughts about Reverse Engineering. I love JavaScript and TypeScript, but sometimes I don't want to create something, but the opposite, to understand how others programs work. Working with IDA and x64dbg is the best thing in the world. Btw, at the beginning I used Ghidra, but after I tried IDA, I liked it more. What do you think, what tool is better, IDA or Ghidra? 🤗

If your memory is hosted, your thoughts are leased. We did not just move our files to the cloud. We moved our working memory. Andy Clark and David Chalmers called it the extended mind in 1998. The thesis was simple. Cognition leaks into the tools we trust. A notebook can be part of your mind if you access it reliably. In 2026, that notebook is a vector database owned by a platform with a legal department. Your extended mind now has terms of service, retention policies, and a compliance team that answers subpoenas faster than you answer email. I am not interested in nostalgia for paper. I am interested in architecture that preserves agency. The fix is not to think less with machines. It is to think locally with machines you control. That is why I built a second brain that lives on a Raspberry Pi 5 with NVMe and a Hailo-8 accelerator, running Retrieval Augmented Generation completely offline. No API keys. No telemetry. No third party that can be compelled to hand over your associative graph. This is the expanded blueprint. More cohesive, more rigorous, and more useful than the usual cloud versus local sermon. The extended mind, now with a landlord The original extended mind argument was about trust and coupling. If you reach for a tool as automatically as you reach for a memory, it counts as cognition. The cloud broke that coupling by inserting a landlord. Your retrieval is fast, but it is also observed, logged, ranked, and retained. Three consequences follow. First, epistemic pollution. When your queries train their models, your future answers are shaped by everyone else’s queries. Your private context gets diluted by the median user. Second, legal exposure. Your prompts, your uploads, your retrieval history, and your embeddings are business records. In many jurisdictions they are discoverable. You cannot plead the fifth for data you gave to a provider. Third, strategic fragility. A policy change, a price hike, a region block, and your cognitive prosthesis goes dark.

Back in February, Uber announced ambitious plans to launch in seven new European markets in 2026 — but now five of those launches are reportedly on hold.

I'm making a platform for simple open source games you can play anywhere. Games are all just JavaScript classes and you can read the source of every game on the platform. I started working on initial "games" (mostly rendering tests) in 2018 and eventually built all of the platform stuff around it to make it easy to share games. There's also an in-browser editor available for you to make and publish games all from the browser. Would love some feedback on the games and studio features as well as t

Here's the failure mode I keep running into. A team gives a coding agent a repo, a task, and maybe a README. The agent can find files and write code, but it still has to guess the operating rules. It guesses the package manager. It guesses which checks matter. It guesses whether generated files are safe to edit. It guesses what "done" means. A README is usually for humans: what the project is, how to run it, and where the important docs live. A coding agent needs different context. Setup rules. Test commands. Boundaries. Completion criteria. That's the gap AGENTS.md fills. The official AGENTS.md guidance describes it as a predictable place for coding-agent instructions: setup commands, test commands, code style, security considerations, and nested instructions for large monorepos. I find the split useful in a more boring way. The README answers, "What is this project?" AGENTS.md answers, "What should an agent know before touching it?" That second question is where the work usually gets fragile. Where Goose Fits Goose makes this less theoretical because it isn't just a chat box. It's an open source local AI agent with a desktop app, CLI, API, MCP extensions, and skills. Without AGENTS.md , I find myself writing prompts like this: Update the docs, but don't touch generated files, use pnpm, run the lint and test commands, keep the PR small, and tell me what you couldn't verify. With AGENTS.md , the prompt can get shorter: Update the quickstart docs for the new config flag. Goose can run the task in the repo. The repo can carry the standing instructions. I noticed this on a small docs/config update where generated files sat near source files. Without repo instructions, the prompt had to carry the package manager, generated-file boundary, checks, and the "tell me what you could not verify" rule. Once those rules lived in AGENTS.md , the prompt became just the task. Not magic. Just fewer chances to forget the boring parts. Where Skills Fit I would add one more layer once
