docker restart does not recreate the container, so changes to volumes in docker-compose.yml only take effect after running docker-compose down && up.
Claude Code Permission Modes Explained: Five Modes from Default to Auto
Claude Code has five permission modes: default (confirm each step), acceptEdits (auto-accept edits), plan (read-only planning), auto (background AI classifier review), and bypassPermissions (YOLO, skip everything). Switch with Shift+Tab or configure via settings.json. Auto mode is the sweet spot — no step-by-step confirmations, but with safety guardrails.
nginx 502: Debugging Cross-Compose Container DNS Resolution
Service names aren't resolvable across Compose projects — you need to add a network alias so nginx can find the container.
Installing and Verifying Superpowers for GitHub Copilot CLI: Implementation, Diagnostics, and Validation
A hands-on log of installing Superpowers (packaged by DwainTR) for Copilot CLI on a local machine — including the diagnostic process when skills didn't appear after installation, the fix, and practical tips.
Docker DNS Resolution: container_name vs network alias
Cross-project DNS resolution requires container_name or a network alias — and only aliases support horizontal scaling.
nginx Restarted Fine, but Cloudflare Keeps Returning 502 — Even Though the Origin Is Healthy
A brief error during nginx restart caused Cloudflare to mark the origin as unhealthy and stop forwarding requests, returning 502 on its own. The key clues: localhost hits to the origin return 200, and nginx access logs are completely empty. Just wait for Cloudflare to automatically re-check the origin — it recovers on its own.
Managing Multi-Service Reverse Proxy with nginx conf.d: A Daodao Case Study
A monolithic nginx.conf becomes unwieldy as services grow. Splitting it into per-service files under conf.d/ via include is the standard solution.
nginx First Request Always 502, All Subsequent Requests Fine
When nginx uses the `set $variable` pattern for dynamic upstreams, the DNS cache expires every 30 seconds — the first request after expiry hits a 502 because no IP is available. Upgrading to nginx 1.27.3 and switching to an upstream block with the resolve parameter fixes this: DNS updates happen asynchronously in the background.
Downloading Files from a VPS Using SSH Config Aliases
Once SSH config is set up, scp works directly with aliases — no need to type out the full IP every time
Ghostty vs cmux: A Guide to Choosing Your Modern Terminal
Ghostty is a fast, native, general-purpose terminal emulator. cmux is a terminal built on top of Ghostty, specifically designed for AI coding agents. They're not competitors — they operate at different layers.
Cloudflare Free Plan Maintenance Page: Custom Error Pages Unavailable, Use a Worker Instead
Cloudflare Custom Error Pages require a paid plan. On the Free Plan, use a Worker with inline HTML to intercept 5xx responses instead.
Managing Personal and Work GitHub Accounts with Git Conditional Includes
Use includeIf + SSH Host aliases to let Git automatically switch accounts based on directory path — no more manual switching.
Conversation as Documentation: Turning Debug Sessions into Blog Posts with Claude Code
After finishing a debug session, just say 'write this up as a post' — Claude Code extracts content from the conversation, applies a template, generates frontmatter, and commits it to the repo. No extra writing required.
