I Generated a Full SaaS UI in 31 Minutes — With One Prompt

No Figma. No CSS. No design system. Just natural language. Designing a SaaS interface takes days: wireframes in Figma, a design system to build, tokens to configure, components to align across pages, dark mode to test. I skipped all of that and built a complete, interactive UI prototype in 31 minutes — using only text prompts. Not a mockup. Not a screenshot. A real Next.js app you can click thro...

Kiwi-chan's Resilience: Logs, Boredom, and Birch Trees!

Another four hours down in the Minecraft world with Kiwi-chan, and it's been... a journey. We're seeing some fascinating behavior emerge, particularly around failure recovery. The AI really doesn't like failing to mine coal, and immediately pivots to simpler tasks like oak and now birch log gathering. It's almost… relatable? The system is diligently following the rules, especially the "Absolute S...

Agent Harness Engineering

A coding agent is the model plus everything you build around it: prompts, tools, context policies, hooks, sandboxes, feedback loops. Harness engineering is the discipline of treating that scaffolding as a first-class artifact, and tightening it every time the agent slips.

A Different Way to Build Rust CLIs: tkucli vs clap

Most Rust CLIs today are built with clap—and for good reason. It’s powerful, flexible, and deeply integrated with Rust. But there’s another approach worth exploring. Two ways to define a CLI clap (code-first) #[derive(Parser)] struct Cli { #[command(subcommand)] command: Commands, } You define your CLI structure directly in Rust. tkucli (config...

Elixir Comprehensions: Learn Enough to be Dangerous

Elixir Comprehensions: Learn Enough to be Dangerous

When you first encounter a for comprehension in Elixir, it looks like a standard loop. But Elixir doesn't have traditional for loops. Instead, comprehensions are powerful pipelines for iterating, filtering, and transforming data all at once. To master comprehensions, we need to understand their anatomy. Let's look at the basic blueprint, and then scale it up to the advanced, infinite chain. ...

I thought I had a bug

The AI I've been building was showing action buttons with labels like "Fight Goatman" attached to an action type called customize_behavior. The label was perfect for the conversation. The action type made no sense. Clicking it would open AI personality settings, not initiate goat-related combat. My first thought was: I have a bug somewhere. Maybe my system prompt is off. Maybe the tool schema i...

Introducing Vectors And Vector Search

Where Traditional Queries Fail Picture this: your dog just birthed a cute litter of say 5 puppies. Now let's assume you have no other pets. If I asked you: "how many pets do you have?", you would naturally say 6. If I asked you: "how many dogs do you have?", you would of course still say 6. Now I asked slightly similar questions, but you were able to parse the question and answer it ...

# Building a Streaming Session Analytics Pipeline with Kafka, Postgres, and dbt

How I built an end-to-end clickstream pipeline with exactly-once delivery guarantees When I set out to build Pulse, I had a specific goal: demonstrate that I could work with streaming data, not just batch. My first portfolio project (Ballistics) was a batch pipeline — API calls on a schedule, Airflow orchestration, daily refreshes. That's the bread and butter of most data engineering work, but...
