My blog has a problem. Or rather it had a problem but I’m making some big improvements to it to make it perform better. For many years, my site has suffered from slow performance. Much of that is my fault though. I tend to overload WordPress with lots of plugins. Plugins are bad, but they are in many ways, quite addictive. There are so many innovative features and functions that you can add to your blog using them that people often suffer from plugin-bloat. And having too many plugins will slow the responsiveness of your site way down. As I said, this is bad, particularly in the eyes of Google who measures how quickly your site responds in its ranking algorithms. So, in order to combat these performance problems, I recently turned to a performance-enhancing cocktail to make my site a bit more performance optimized: MaxCDN, Nginx, CloudFlare and WordPress caching.

Just to set some expectations here, this article is NOT a how-to post on any of these items. It is more of an outline of some things that you can do to optimize your site. If I were to walk through step-by-step of each and every item, you would either be bored to tears or have to scroll endlessly through a 10,000+ word article. There are many how-to articles out there on how your can configure each of the items that I mention below. But, from my perspective, what I view as critical is actually implementing one or all of my recommendations.

The topics that I’m covering are:

  • Using a Content Delivery Network (CDN)
  • Moving from Apache to Nginx as your web server
  • Utilizing CloudFlare
  • Enabling a WordPress caching plugin

Post image for How To Fix “The Required File Cannot Be Found” Error When Syncing an iPhone or iPod Touch

Every since I had to restore my iPhone 4 from a backup, I have been having a pesky error message popping up each and every time I would sync my iPhone with iTunes on my Mac. It cryptically said “The iPhone [insert your iPhone name here] cannot be synced. The required file cannot be found.” Nothing more. No error message to search for. Nada. A quick Google search on that error, however, produced some good results, and, in the end, fixed my issue, so I figured I would share and prevent future head-pounding-on-the-desks from others.

The fix is incredibly easy. Essentially, your Photo Cache may have become corrupted and you simply need to delete it.

Here are the steps (for the Mac – I’m not sure if this issue exists for Windows users):

  1. Close iPhoto on your Mac.
  2. In the Finder, go to your HOME folder.
  3. Open the PICTURES folder.
  4. Navigate to the file called “iPhoto Library“:
    iPhotoLibrary
  5. Right-click on that file and choose “Show Package Contents“:
    show_package_contents
  6. Within the Package Contents folder, find and right-click on the file called “iPod Photo Cache” and select “Move to Trash“:
    ipodPhotoCache
  7. Empty your Trash.
  8. Close the Package Contents folder.
  9. Re-sync your iPhone.
