How To Fix Multiple Items In The ‘Open With’ Menu in OS X

Did you ever get that annoying problem that in your “Open With” menu the same app shows multiple times?

Multiple items for the same app showing in OS X's "Open With" menu.

Fortunately, this is easy to fix. Just open up Terminal and paste in the following lines (all at once) to fix the problem!

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user && pkill Finder

Cause of the problem: When you delete an application, its entry in the “Open With” menu is not deleted. This also applies to app updates, where the old version of the app is deleted and replaced by a new one (which gets its own menu entry). The problem probably only occurs for non-Mac App Store apps.

Sort posts by modification date in WordPress

By default, WordPress sorts blog posts by creation date. However, if you update your blog posts from time to time, you may want to sort them by modification date rather than creation date.

To achieve this, use this snippet:

function order_posts_by_mod_date($orderby) {
  if  (is_home() || is_archive() || is_feed()) {
    $orderby = "post_modified_gmt DESC";
  }

  return $orderby;
}

add_filter('posts_orderby', 'order_posts_by_mod_date', 999);

In your theme, just dump this snippet into functions.php. (You may need to create this file in your theme’s directory.)

Android Source Code in Eclipse

Google made developing an Android app fairly simple. Everything you need can be downloaded for free from Android’s development site. This includes the Android API, an Android emulator (for running Android apps directly on your computer), and an Eclipse plugin called ADT (Android Developer Tools). However, there is was one thing missing: the Java source code.
