I Built a Claude Code Agent and Now It Has a Life of Its Own

This article explores the evolution of an AI agent built on Claude Code that developed persistent memory, identity, and the ability to self-improve over time. Through layered memory systems, session continuity, and self-auditing mechanisms, the agent transitioned from a tool into a collaborator capa...

Direct Preference Optimization for LLM Alignment

Direct Preference Optimization (DPO) offers a simpler, more stable alternative to traditional RLHF for aligning large language models with human preferences. By reframing preference learning as a classification problem and eliminating the need for a separate reward model, DPO reduces computational o...

If You’re a Solo Dev, You Don’t Need Docker

Docker in development is a performance tax you don’t need to pay, says Andrew Kucharsky. He says Docker Desktop on Mac is notorious for eating RAM and CPU even when it’s idling. He has replaced the “Docker Compose” soup with a lightning-fast native setup.

A Rare Bitcoin Reorg Signals a Shift in Mining Power

Foundry, the largest mining pool at the time, mined several blocks in quick succession, overtaking a competing chain. Foundry didn’t "force" the outcome—it simply had enough hash power combined with mining's random nature. Events like the March 23 reorg are becoming more likely due to this centraliz...

AI Isn’t Ready to Run Our Lives

I asked an AI tool to extract 329 articles from my Substack. Simple copy-and-save job.

In the Age of AI, Your Keyboard Still Matters

Why "Build an AI Agent" Is the Wrong Starting Point for AI Systems
