Ruslan Yakushev's Blog: WinCache and WordPress plugin upgrade problem

Fri, 15 Apr 2011 10:12:51 -0500

In a new post to his blog Ruslan Yakushev points out a new build of WinCache (the Windows caching tool for PHP) that makes life easier for WordPress users who want it to be able to to the auto-upgrade correctly.

The WinCache extension 1.1 for PHP has been released last year. Since then several customers reported a bug in the extension that prevents WordPress and other PHP applications from performing automatic upgrades or their plugins. This was reported on WordPress forum as well as on WinCache forum. The new build of WinCache with the fix for this problem is available now at the following location: https://sourceforge.net/projects/wincache/files/development/

He asks for feedback if things still don't work - either as a comment in the WinCache forum or as a bug to the PECL database. This will help them improve the support in future releases and make it even easier for those running WordPress on Windows to keep their sites running smoothly.

Mpwebwizard.com: Use a mirror for hits from popular websites

Mon, 18 Dec 2006 15:49:00 -0600

There's a tutorial over on mpwebwizard.com that's been updated and talks about using a mirror to handle hits from a popular website (like digg or slashdot).

caching services such as coral content distribution network provide an alternative for when your site goes down, but why wait until it gets to that stage? why not just send all your hits from high-end websites to the coral cache version? well, there isn't a good reason not to, so i'll show you how to do it automatically.

He provides the simple script that looks for certain sites in the "HTTP_REFERER" value of incoming calls and pushes them off to the cached location with a header() redirect. The whole thing is only 12 lines, not counting the $sites array.

Bubble.ro: How to create the histogram of an image using PHP

Wed, 01 Nov 2006 10:18:43 -0600

On the Bubble.ro website, there's an interesting tutorial that guides you through the creation of a histogram for any image (that PHP can handle) automatically with a little GD functionality.

The algorithm to calculate the histogram for an image is pretty straight forward if you know how to extract the RGB value of each pixel, by counting the number of pixels of each value (and then divide by the total number of pixels in order to get a normalized value).

They share the simple script that grabs the image's data, analyzes it, and, superimposed on one corner of it, places the histogram image. They have the full source and examples available for download.
