Docker Cleanup ​

shell
docker system prune  # Clear cache, will remove containers
docker image prune   # Remove unused images only
docker volume prune  # Clean up volumes
docker system prune  # Clear cache, will remove containers
docker image prune   # Remove unused images only
docker volume prune  # Clean up volumes

Delete Docker Container Logs ​

shell
echo "" > /var/lib/docker/containers/<container-id>/<container-id>-json.log
echo "" > /var/lib/docker/containers/<container-id>/<container-id>-json.log
  • Note: this breaks docker log --tail 100 <container-id>
  • Specify log options at startup instead:
shell
docker run \
  --log-driver json-file \
  --log-opt max-size=10m \    # max 10MB per log file
  --log-opt max-file=3 \      # keep at most 3 old log files
  your_image
docker run \
  --log-driver json-file \
  --log-opt max-size=10m \    # max 10MB per log file
  --log-opt max-file=3 \      # keep at most 3 old log files
  your_image

VSCode Auto-Format on Save ​

To configure Prettier to auto-format on save in VSCode:

  1. Install Prettier extension — search "Prettier - Code formatter" in the marketplace.

  2. Enable format on save — open Settings (Ctrl+, / Cmd+,), search editor.formatOnSave and enable it.

  3. Set default formatter — search default formatter, set Editor: Default Formatter to esbenp.prettier-vscode.

  4. Prettier config — create .prettierrc in your project:

    json
    {
  "semi": true,
  "singleQuote": true,
  "tabWidth": 2,
  "trailingComma": "es5"
}
    {
  "semi": true,
  "singleQuote": true,
  "tabWidth": 2,
  "trailingComma": "es5"
}

  5. Workspace settings — create .vscode/settings.json:

    json
    {
  "editor.formatOnSave": true,
  "editor.defaultFormatter": "esbenp.prettier-vscode"
}
    {
  "editor.formatOnSave": true,
  "editor.defaultFormatter": "esbenp.prettier-vscode"
}

Useful Tools ​

  • Surge — powerful packet capture tool
  • AdsPower — fingerprint browser for daily work

Intercept Network Requests (New Approach) ​

Inject into a webpage and override XMLHttpRequest.prototype.send and fetch — suitable for browser extensions.

js
const origFetch = window.fetch;

window.fetch = async (...args) => {
  const [resource, config] = args;
  let requestUrl;
  if (typeof resource === "string") {
    requestUrl = resource;
  } else if (resource instanceof Request) {
    requestUrl = resource.url;
  }

  if (config.method != "POST" || !requestUrl.includes("/overview/home/asr")) {
    return origFetch(...args);
  }

  if (config && config.body instanceof FormData) {
    const entries = {};
    for (const [k, v] of config.body.entries()) {
      if (v instanceof File) {
        entries[k] = { name: v.name, size: v.size, type: v.type };
      } else {
        entries[k] = v;
      }
    }
    config.body = JSON.stringify(entries);
    config.headers["Content-Type"] = "application/json";
  }
  return origFetch(...args);
};
const origFetch = window.fetch;
