Actually, I managed to fix a freezing bug regarding failure during hash check for a week. Unfortunately, I can’t commit the patch to CVS at cvs.sourceforge.net because of connection refused error. It seems sourceforge is trying to force every projects to migrate to Subversion as soon as possible. They don’t want to maintain CVS anymore so CVS is now very unstable and nobody takes core of them for a week.

According to larry’s request, it is a long story so I explain how Technorati works in this separate post instead of so long comment. Technorati is actually a specific search engine focusing on providing service involving blog, blog, and blog. Generally, search engine is a key component of surfing Internet today. Nobody knows where the information they are looking for are, especially blog. Blog is not just old fashion web content but in fact, it could be categorized as up-to-date content. In other words, blogs are frequently updated than normal web page. Though, blogs are not similar to dynamic pages like webboards or forums because they are contentful and are usually in medium length. Since blogs are updated so often, search engines must update their indexes as fast as possible. How to do that? Polling is not good enough in this situation so someone proposed asynchronous solution to solve this problem. The result is XML-RPC Ping service. This solution pushed additional duty to content publishers or content management software so Ping server will be notified about the update of given URL.

After so long waiting for a few months, Drupal 4.7.0 RC1 is out there. Hopefully, this is the last release candidate so we could see Drupal 4.7.0 full release very soon. I will upgrade howforge.com tomorrow. Unfortunately, there is another one critical issue left in queue. So we should see RC2 shortly.

XML is a popular data format because of its flexibility and extensibility. It is widely used to describe hierarchical data. For any data format, you need at least 2 operations: read and write. Basically, XML data is in form of tree. Once you have the XML tree, you can generate XML by walking through all nodes in that tree. So the biggest problem is to read XML tree from text stream, text file or text string. This process is usually called as parsing.
