WordPress is biggest on all accounts, but when you look at dollars spent, WordPress is only just about 50%.

I've worked on sites in the past where I needed to get two values out of a custom field. For example, I was creating an eCommerce site where some products had options. The options were in a dropdown menu. Each option in the dropdown had a value for what you actually see, and then another value for how that option effected the price. When entering a custom field, I often did it like this:
New WordPress-only snippets repository. Nice clean design, good functionality, quality content (like this gem). This one should be a winner. Update (2013/08/29): 404 link removed (
WPCandy is back under Ryan Imel and it's been loaded with good stuff lately, including this great run-through of how to use Chris Shiflett's URL sentences idea in WordPress.

Peter Wilson walks us through making sure print stylesheets are loaded after the rest of the page is loaded, so they don't hold up page rendering.

Pardon my ignorance here, but Rasmus starts talking about latency and concurrent requests about 16:30. He then mentions "one line of code" installation of something that sounds like "aqua code cache" that gives WordPress a 3x performance boost in response time / number of transactions per second. Anyone knows what he's talking about there, shoot a note and I'll update this permalink with the info. He goes on to talk about much more hardcore-PHP-nerd WordPress optimization stuff.
The scoop via Joost Schuur:
Rasmus is talking about an 'opcode cache'. It essentially caches the parsed PHP scripts in memory. That means PHP doesn't have to read it from disk or even convert the humanly readable PHP script code into executable machine code (opcode). The one he's referring to is APC, which is likely going to be included in the next big release of PHP. Xcache is another popular kind. I run it on my site and got about a 3x performance increase on page request server times, so the numbers add up. The W3 Total Cache WordPress plugin has the option of using Xache or APC to keep popular pages in memory via opcode caching.
Just a reminder that WordPress version 3.0.1 is available, so take a few moments and update your website. Staying current is one of the best ways to keep things running smooth, safe and secure. The new version addresses about 50 minor issues and helps to make WordPress 3.0 even better.
Amazingly, WordPress 3.0 was downloaded nearly 11 million times in 42 days. So HUGE congrats and thanks to the entire WordPress crew for an amazing piece of software.
