The article outlines a method for coding on the go, dubbed "Doom Coding." The author shares a personal experience of coding remotely using a smartphone and a computer that runs 24/7. By using tools like Tailscale, Termius, and Claude Code, users can access their computers from anywhere with an internet connection. The setup involves a quick five-minute process including installing necessary apps, enabling SSH, and adjusting access controls. Key components include a smartphone, a computer that never sleeps, and a Claude Pro subscription. Installation steps for Tailscale and Termius are provided, along with troubleshooting tips for establishing a connection. Notably, the author encountered a peculiar issue where a closed laptop connected to a monitor would disconnect from Tailscale after a brief period, which was resolved by changing the setup. The guide emphasizes the importance of disabling IPv4 for successful connectivity via MagicDNS. To test the connection and start coding, users can run a simple HTTP server on their computer and access it through their phone's browser. The author encourages readers to share best practices and feedback to enhance the coding experience. Contact information is provided for those interested in connecting or offering suggestions.
