Most AI support agents can talk. Very few know when to talk first. That's the gap Teachable ran into with Fin, its AI support agent. Fin could answer a ticket the moment someone opened one. What it couldn't do was notice a user quietly struggling on...

Every Go service that does I/O — database calls, HTTP requests, queue polling, file reads — should be passing a context.Context through every layer. In practice, a large number of codebases treat context.Context as optional plumbing that gets added l...

Go makes concurrency feel easy. Goroutines are cheap, channels are built into the language, and the standard library gives you everything you need to spin up a worker pool in under 30 lines. That ease is genuinely valuable — but it also means bugs sn...

Quick Overview MVP stack decisions affect burn rate, iteration speed, and how easily a product can pivot after early user feedback Frontend framework choice trades short-term development speed against long-term maintainability and hiring poo...

Web performance has traditionally always been about human user experience. In recent time, that has evolved to include AI agents as well. AI agents can be thought of as anonymous and agentic systems that browse, consume and interact the web on behalf...

RAG Retrieval-Augmented Generation - where an LLM answers questions using retrieved document chunks breaks most often before retrieval even starts. The question going in is underspecified, and no retrieval system can compensate for a bad query. The ...

If you've ever built a search endpoint, you've hit this wall. Your query has filters, sort orders, a nested set of facets, maybe a geo bounding box. It doesn't fit in a URL, and cramming it into query string params is ugly and fragile. So you reach f...

The eCommerce industry has become more competitive than ever. With thousands of online stores selling similar products, pricing alone is no longer enough to influence buying decisions. Customers now expect brands to understand their preferences, reco...

> There is a diary behind this — five entries of a self-taught web developer and an AI agent cutting a door in the memory wall so a 235-billion-parameter frontier model could run off the SSD of a 48 GB MacBook. You don't need any of it to read this o...
