The Skill Ecosystem Has a Locked Door Problem — So I'm Building the Lock

I've been using Claude Code and agent skills heavily for the past several months. At some point it clicked: the model is just the engine. The skill is the intelligence. That realization led me to a question that I couldn't find an answer to anywhere: if skills are this valuable, why does the entire skill ecosystem treat them like open-source recipes that anyone can copy? What's Broken T...

Cost-Effective Observability: The 80/20 Stack for Startups

You Don't Need Datadog (Yet) I see startups spending $5,000/month on Datadog with 8 engineers. That's $625 per engineer per month for monitoring.

Chapter 4: The Bigram Model - Simplest Possible Language Model

What You'll Build A character-level language model that predicts the next character based only on the current character. No neural network, no gradients, just counting. A "bigram" is a pair of consecutive tokens (like 'e' followed by 'm'), so a bigram model is one that learns which pairs occur most often. Notice that this model uses plain double arrays, not Value objects. That's becaus...
