Configuration Updates

Docusaurus Config (website/docusaurus.config.ts):

editUrl: ({blogPath}: {blogPath: string}) => {
  return `https://github.com/qiniu/techcamp/edit/blog/website/blog/${blogPath}`;
}

This ensures "Edit this page" links point to the blog branch for direct editing.

Migration Script

Added translate_to_english_slugs.py - automated script that:

• Maps Chinese titles to English slugs
• Renames files with English slugs
• Updates frontmatter with new slug format
• Maintains all metadata (authors, tags, dates, descriptions)

Benefits

1. SEO Improvement: English URLs are more search-engine friendly
2. International Reach: Better accessibility for non-Chinese speakers
3. URL Stability: Semantic English slugs are easier to remember and share
4. Direct Editing: Edit URLs point to blog branch for streamlined workflow

Testing

• ✅ Build succeeds: npm run build passes
• ✅ All 21 articles migrated successfully
• ✅ All frontmatter validated
• ✅ Image references maintained

Closes #51
