    • visual studio code - How can I bind mount to a vscode devcontainer without hard-coding it in devcontainer.json - Stack Overflow
      • I keep my configs within Docker volumes. There is an example:
      • devcontainer.json file

      • {
        "initializeCommand": ["init-host.sh"],
        "mounts": [
          "type=volume,source=devvolume-gcloud,target=/root/.config/gcloud"
        ]
        }

      • init-host.sh file

      • #!/usr/bin/env sh
        set -e
        
        docker context use default
        docker volume create devvolume-gcloud

• 1Password
  • Q: How to disable Cmd+\ keyboard shortcut in 1Password desktop app?
    • This shortcut conflicts with some development tools (also reported conflicts with rich text editors, Google Docs, Keyboard Maestro)

    • Research Findings

      • Cmd+\ is the Lock 1Password shortcut (not 1Password/Quick Access)
      • 1Password/Quick Access uses Shift+Cmd+Space on Mac
      • According to keyboard shortcuts documentation, shortcuts can be customized in Settings > General

    • Solution

      • Navigate to 1Password > Settings > General
      • Find the keyboard shortcuts section
      • Leave the shortcut field blank to disable it, or change to a different key combination
      • According to 1Password Community discussions, users confirm "when I disable the 1Password shortcuts (by leaving them blank), the conflict resolves"
      • Created 1Password/How To/Disable Keyboard Shortcut with detailed steps
• DevContainer Documentation Updates
  • Created DevContainer/Docker Compose/Concept/Using Docker Compose - comprehensive guide on using Docker Compose with DevContainers
    • Covers production file preservation, override files, sequential processing, and best practices
    • Includes examples of multi-container setups and service networking
  • Created DevContainer/Rust/How To/Configure Debugging - guide for configuring Rust debugging in containers
    • Documents required capabilities (SYS_PTRACE) and security options (seccomp:unconfined)
    • Covers both Dockerfile and Docker Compose configurations
    • Includes VS Code debugger setup and troubleshooting
  • Updated DevContainer main page with links to new documentation
• GitHub/Codespace Documentation Created
  • Created comprehensive GitHub/Codespace page for using GitHub Codespaces with long-running Claude/Code sessions
  • Key Findings for Long-Running Sessions:
    • CRITICAL: Closing browser/editor does NOT stop the codespace - processes continue running
    • Perfect for AFK Claude/Code sessions that can run up to 4 hours (240 min timeout max)
    • Timeout configurable from 5-240 minutes (default 30 min)
    • Must explicitly stop codespace to avoid charges
  • Machine Types & Pricing:
    • 2-core ($0.18/hr) to 32-core ($2.88/hr)
    • Recommended: 4-core or 8-core for Claude/Code
    • 8-core = $0.72/hr = $2.88 for 4-hour session
    • Storage: $0.07/GB-month
  • Free Quotas (Personal):
    • GitHub Free: 120 hours compute + 15 GB storage/month
    • GitHub Pro: 180 hours compute + 20 GB storage/month
  • Recommended Workflow:
    • 1. Start codespace with 240-minute timeout: gh codespace create --idle-timeout 240m
    • 2. Launch Claude/Code session
    • 3. Close browser/editor - session continues
    • 4. Reconnect later to check progress
    • 5. Explicitly stop when done: gh codespace stop
  • Documented machine types, lifecycle, persistence, environment variables, and billing
  • Added references to official documentation for all features
• Blog/Simon Willison/Claude Docs Best Practices
  • Created page for Simon Willison blog post on Claude documentation best practices
  • Key insight: Use @AGENTS.md in CLAUDE.md to maintain a single source of truth for agent configurations
  • Enables centralized configuration management and prevents duplication
