Shop Network’s First Video Commercial on Youtube

In an earlier blog post, Royalty Free Music for YouTube Videos, I described how and where to find music that will not get you into trouble due to copyright infringement. Taking my own advice, I grabbed several songs made by Stefan Gustafsson and have included them in this video “commercial” for this website.

Yeah, I know that this is an amateurish video, but at least I can say that I created it from scratch. I used a freeware program known as “Demoawy” to capture video from the screen, and then I used Windows Movie Maker on Vista x64 to compile the video with audio.

If you’re using a php accelerator, in particular, if you’re using APC PHP Accelerator, your Wordpress Blog can receive a distinct performance boost. Since Wordpress uses PHP with a mySQL backbone, optimizing PHP and/or mySQL will result in a faster Wordpress Blog.

PHP Accelerators

• A PHP Accelerator focuses on optimizing PHP by caching the compiled output of PHP code. In other words, when using a PHP Accelerator, a page using PHP code does not need to recomple on every page request — just when something in the code changes. This saves CPU time, and helps a server to render information faster.

I came across an interesting PHP file that uses APC as the backend for the WP Object Cache v0.2. On this website, I’m using v0.2.1. To be honest, I have not done a file comparison between v0.2 and v0.2.1 in order to see the differences — all I know is that v0.2.1 works on this site with the latest version of APC, v3.0.19.

Remember to view the information contained in the file. It says, “Install this file to wp-content/object-cache.php”

I recommend enabling the number of mySQL queries before installing this APC Plugin for Wordpress. This code might be useful for this purpose:

<p style=”margin:0;padding:0;”><?php echo get_num_queries(); ?> <a rel=”nofollow” href=”http://www.mysql.com/”>mySQL</a> queries executed in <?php timer_stop(1); ?> seconds.</p>

What you should see is a reduction of the number of mySQL queries when your blog page/post is refreshed. Of course, all of this assumes that you have the Query Cache enabled in mySQL.
