I had set aside some time to integrate Fathom Analytics this morning. Took me less than 5 minutes lol. Really enjoying the interface so far – obvious "don't make me think" vibes

Nice one, some good tricks in there. I think these practices will all consolidate over time, be it through official features or commonly-accepted good practices
How we use Claude Code - Geocodio
Claude Code is only as good as the context you give it. I've been building out a custom setup with skills, hooks, and MCP servers that's turned it into a genuine productivity multiplier for our Laravel codebase. Here's how we teach Claude our patterns, auto-suggest relevant skills on every prompt, and persist context across sessions for multi-day features.

Fair assessment of the state of AI coding
Promoting AI agents
At the end of last year, AI agents really came alive for me. Partly because the models got better, but more so because we gave them the tools to take their capacity beyond pure reasoning. Now coding agents are controlling the terminal, running tests to validate their work, searching the web for documentation, and using web services wit...

Despite being pretty clear on the difference, I still sometimes struggle to decide whether an object is a Data Transfer Object or a Value Object. I've just realised that it may be because it's actually a Parameter Object
Introduce Parameter Object
Problem: Your methods contain a repeating group of parameters.
Solution: Replace these parameters with an object.
