If you examine the preferences dialog of any modern Web browser (like Internet Explorer, Safari or Mozilla), you'll probably notice a 'cache' setting. This lets you set aside a section of your computer's hard disk to store representations that you've seen, just for you. The browser cache works according to fairly simple rules. It will check to make sure that the representations are fresh, usually once a session (that is, the once in the current invocation of the browser).

This is awesome. I was so fed up with trying to find a fail-proof, cross-platform way to find the mime type of an image using PHP that I wrote a quick function that utilizes the same technology as the exif_imagetype, getimagesize, and finfo functions do. Ahh the joys of low-level.

Advanced Web Development by AskApache is a Firefox Collection I created since I'm always trying new Addons out and using multiple computers and I wanted a quick and easy way to install my favorite's and keep a running list. Firebug, YSlow, LastPass, and Web Developer are the only ones I always use regularly.
I like the idea of the last.fm but it's not as powerful as the site, which is awesome. Lately listening to Kings of Leon Radio...

How I was able to preload many flash flv and swf files on one of my clients sites that has a lot of online video and relatively small traffic. Their site visitors would usually watch 3-10 videos per visit and so to make the videos load almost instantly on every page I came up with a way to preload the top 10 .flv files and the swf flv player files as soon as the visitor successfully started watching the 1st video. Of course I also setup .htaccess caching on the server so that once they downloaded the files into their cache they would never request them from the server again. I was having fun with this so its pretty funky and uses some really cool combinations of javascript, swf preloader from xml, css classes to help automate it all..

Time-dependant rewriting uses mod_rewrite and apache server time variables to display different files depending on the time, while the URL stays the same. An often requested implementation of this is to display a different home page or image depending on if its morning, noon, or night.

Well what can I say, other than this is sooo DOPE! Here is a list of the modules this plugin (version 4.7 unreleased) will automatically detect. I compiled the list myself using every module included with any default Apache installation for ALL the versions listed below, 1.3 to 2.2+
Want to know something else I'm including in this plugin? For each and every module that is detected, this plugin can then detect ALL of the modules .htaccess Directives! For instance, RewriteRule, AccessFileName, AddHandler, etc.. are each a directive belonging to a module that is allowed to be used from within .htaccess files.
Talk about sick.. these tricks have the diamond disease!

To prepare for several upcoming articles on AskApache that are focused on optimizing Servers and Sites from a server admin level, here is an article to introduce the main tools that we will be using. These tools are used to optimize CPU time for each process using nice and renice, and other tools like ionice are used to optimize the Disk IO, or Disk speed / Disk traffic for each process. Then you can make sure your mysqld and httpd processes are always fast and prioritized.
