Building Stateful AI Agents with Backboard: A Complete Feature Deep Dive

The AI agents have evolved far beyond simple chatbots. They're evolving into autonomous systems capable of reasoning, remembering, retrieving knowledge, and executing actions. But building such systems from scratch? It usually means stitching together: Vector databases Memory layers Tool orchestration frameworks Context pipelines Multi-agent coordination That's exactly where the Backboard com...

A declarative CLI framework in Rust

I built a declarative CLI framework in Rust (define your CLI in TOML) Most Rust CLI tools are built with libraries like clap. They’re powerful—but also verbose. After building a few internal tools, I kept running into the same problem: Too much boilerplate for simple commands Repeating argument parsing logic Hard to manage growing CLI complexity So I built tkucli — a declarative CLI frame...

AI startup claims to automate app making but actually just uses humans

When "AI Automation" is Just Human Labor: A Developer's Reality Check The AI landscape is a minefield of hype and promises. As developers, we're constantly sifting through marketing fluff to find the actual signal – the tools, frameworks, and methodologies that genuinely push boundaries and solve real problems. So, when a story breaks that pulls back the curtain on a supposed "AI app de...

AI Agents Are Killing Seat-Based SaaS Pricing. Here's What's Replacing It.

AI Agents Are Killing Seat-Based SaaS Pricing. Here's What's Replacing It. Intercom's Fin AI agent went from $1M to $100M+ ARR on one pricing move: $0.99 per resolved ticket. Not per seat, not per month. Per outcome. Fin now handles 80%+ of Intercom's customer support volume and closes about a million conversations a week, and Intercom will refund up to $1 million if resolution targets ...

I built a free Java practice platform because everything else was broken After helping a few friends learn Java, I kept hitting the same wall: Every “practice Java online” site is either: paywalled full of ads or only focused on LeetCode-style puzzles that don’t actually help you write Java So I built Java Practice Lab — a free, no-signup playground with: 250...

How I built a tool that converts SVG files into 3D letter fabrication files (STL + DXF)

The problem Every time a client wanted dimensional letters — for a sign, an installation, a storefront — I hit the same wall. Either I had to hire a 3D modeler, or spend hours in Blender manually extruding paths, fixing normals, and setting up tolerances for the acrylic slot. Neither option was good. Hiring someone adds cost and back-and-forth. Blender works, but it's slow and ove...
