Responder is an AI bug-fixing agent that plugs into the Sentry or Datadog Slack channel you already run. One-click synch, no new telemetry to install. On every alert it investigates with full context, filters out the noise, and for real issues replies right in the thread with the root cause, the evidence, and a mergeable PR. Prompts, memory, repo access, and escalation rules are fully customizable, so you're building your own debugging agent, not renting ours.

Yamanote 3D is a free browser experience inspired by Tokyo’s Yamanote Line. Walk through an E235 carriage, sit down, watch the city, listen to announcements, and get off at stations. I built it to have realistic train sounds and city ambience in the background while studying or working. Feedback is very welcome.

ps, top and lsof tell you what is running. witr tells you why. Point it at a process, PID, port, container or file and it traces the chain that explains it - systemd, supervisor, shell or cron - plus who started it, when, from where, and the warnings worth knowing. Run it bare for an interactive TUI with Processes, Ports, Containers and Locks tabs. Or script it: --short for a one-line chain, --json with real exit codes. One static Go binary for Linux, macOS, Windows and BSD.
