Free up memory in OSX Mavericks

Screen Shot 2014-03-05 at 11.23.16 PM

Lately I’ve noticed  that Mavericks OSX is consuming almost 8GB of memory which I have no idea why it used too much when I don’t have much app running. In order to free up the memory in OSX, you can try by typing

purge

or

sudo purge

in terminal in which OS X will free up the “inactive” memory.

How to show hidden files in Mac Finder

This is the missing little feature in Mac that Apple doesn’t want to add it? In Windows, you can just check the show hidden files and folders in File and Folder options. In order to see hidden files and folders in Finder, open the Terminal from Applications->Utilities->Terminal. Type the following command line.

defaults write com.apple.Finder AppleShowAllFiles YES

show-hidden-files-mac-finder

To hide the files and folders back, just set it to NO. I hope this help.

defaults write com.apple.Finder AppleShowAllFiles NO

Keep it simple. Stay focused and keep shipping

It’s been more than a year I didn’t write or I don’t look back my blog. It was stupid to leave the blog that gave me extra income. I think it is time to organize my time to write a new post every week.

Adding class in li under WordPress Navigation Menus

In WordPress, you can generate menus by using wp_nav_menu function. It will show the menus you set in admin. Here is the example of menus in html version.

<ul id="menu-header-menu" class="menu">
  <li class="wordpress generated classes">
     <a href="#">Menu Name</a>
  </li>
  <li class="wordpress generated classes">
    <a href="#">Menu has sub menu</a>
   <ul class='sub-menu'>
     <li class="wordpress generated classes">
         <a href="#">sub menu item</a>
     </li>
     <li class="wordpress generated classes">
         <a href="#">another submenu item</a>
     </li>
   </ul>
  </li>
</ul>

For some reason, you want to let your visitors know that the menu has sub menus by showing arrow or drop down icon next to the menu. In this case, you’ll need to add CSS in li element that it has child menu. There is an answer to this on stackoverflow by adding some php codes in functions.php. I found that there is an alternative way to solve this problem by using jQuery. If you’re familiar with jQuery, the following line that I used for my WordPress theme will help you with this problem.

<script type="text/javascript">
        $(document).ready(function(){
            $('.sub-menu').closest('li').addClass('has-submenu');
        });
</script>

You can add the above code before head or at the end of your theme. It will add ‘has-submenu’ in li elements of wordpress menu that has sub menus. I hope this help.
