Slightly more than a month ago I left my job as team-lead of eZ Components at eZ Systems behind, to focus on something new. During the past month I've been contemplating about what to do next and realized that I do not want to take on a new full-time position right away. Instead I will be available to work on (custom) PHP extensions and internals related issues. Extensions are a great way around PHP's limitations and performance issues.
As first project I am working on a "QuickHash" extension for StumbleUpon. This extension circumvents PHP's hefty memory (and performance) overhead by providing more specific data structures. The extension currently implements integer sets and integer to integer hashes. I am now adding integer to string hashes and string to integer hashes. The QuickHash extension will be released under the PHP Licence and I will dedicate another post to it later.
