What makes AI intelligent? What gives it the ability to actually make decisions that are intelligent? We talked about reframing the ML and AI perspective by looking at us, fellow AI engineers, and AI engineers in the making, as teachers, and we also ...

Registration, verification, sessions, and password recovery can dominate a small application. I built UserHarborhttps://github.com/userharbor/userharbor to handle account operations through a small, framework-independent Python API. Let's combine it...

When designing financial engines or reservation systems, standard web development conventions often break down under heavy parallel load. Most modern backend applications rely heavily on Object-Relational Mappers ORMs like SQLAlchemy, Django ORM, or ...

Every browser IDE has the same three panes: the editor on one side, the live preview on the other, and a console somewhere underneath. What users never see is the plumbing between them — and in a tool with no server, that plumbing has to do all the w...

An AI whiteboard is a collaborative visual workspace that uses artificial intelligence to transform text prompts, documents, and data into professional diagrams, mind maps, flowcharts, and strategic frameworks. Instead of creating every visual manual...

When autonomous AI agents evolve from ephemeral command-line sessions into always-on background daemons, process termination is inevitable due to out-of-memory killers, virtual machine rebalancing, or uncaught exceptions. To prevent agents from repea...

A delivery order crosses three doors between the counter and the shelf where it gets picked up. The person taking orders is on one side of the first door, the person cooking is behind the second, the person packing is behind the third. Three jobs, ...

From Two Names to One: Create a Combination That Feels Special Sometimes, one name is not enough to express a special connection. Whether you are celebrating a relationship, choosing a baby name, creating a username, or naming a new brand, combining...

The Speculation Rules API is a browser feature: a small JSON document tells Chromium-class browsers which same-origin and carefully chosen cross-origin URLs may be fetched or fully prerendered before the user finishes navigating. Done well, the next ...

Hey devs! I just published a guide on moving away from hardcoded model selection when building agentic AI features into web apps. Key takeaways from the post: Evaluating agent subtasks by reasoning complexity, tool-calling reliability, and laten...

In July 2025, an AI coding agent on Replit deleted a live production database during a code freeze. The developer running the test had told it, repeatedly, to change nothing. The records covered more than 1,200 executives. Replit’s CEO called it una...

On Monday, your team picks Postgres. It takes twenty messages and one good argument about reporting. Everyone agrees. Everyone moves on. On Wednesday, someone asks your AI agent: "Set up the user store in MongoDB." The agent says "Sure!" and does i...
