I have some friends, here are some of their great sites:

• Indika Udagedara — practical Linux system administration and hands-on C++/Python projects, from face-recognition software to network session tracking and open-source tooling.
• Andrei Gec — a developer's portfolio of TypeScript/JavaScript open-source projects and curated articles on modern web development, including micro frontends.
• Simon Mackinnon
• Matt Coles — an AWS Principal Engineer's journal on cloud infrastructure, AI/ML tooling, and homelab experiments (AWS CDK, Tailscale, Python AI agents, vision models).
