4. Code Standard
• PSR-0, PSR-1, PSR-2
• Bundle Structure Best Practices
• Bundle namespace:
• SmvnSomeCoolBundle
• SmvnBundleSomeCoolBundle
• SmvnBundleSmvnSomeCoolBundle
• Service naming, Route naming
• Prefix with bundle name and vendor name (for reusable bundle)
• Use service alias (image_resizer vs. smvn_image_resizer)

7. Reusability
• Template inheritance
• Template macro
• Twig Extension
• Base Controller / Embed Controller
• Service
• Form Type
• Bundle (try knpbundles.com)
• Extract bundle from project for reusability

8. Pitfall
• Security Context: isGranted() vs. hasRole()
• Event Listener vs. Event Subscriber
• Doctrine Schema Update vs. Doctrine Schema Migration
• app/cache, app/logs write-permission: Never use umask
• Nesting limit in xdebug
• Case sensitive Annotation name (@Entity vs @entity)
• Avoid using dev-master in composer.json
• Update vendor  Clear cache  Clear Assetics  Update schema
