I have just read about OpenCARE project to convert any data format to EDXL. This is a good idea to integrate incompatible data formats that conceptually indicate to the same meaning. For example, organization A may store people database in MySQL, organization B stores people database in MS Access with totally different schema, and organization C stores people database in MS Excel. It is also impossible to force all organizations to use the same data format so OpenCARE is designed to convert any data format to XML-based format like EDXL which is an oasis standard.

I have used Bazaar-NG aka bzr for a month. It works well and I like it so much because I don’t need to have network to commit my change. The installer for win32-based system works perfectly on my laptop. Unfortunately, there is no official bzr distributed in RPM. I have to build it myself. This action is terrible for me because bzr requires at least Python 2.4. Below are my step to successfully install bzr on Fedora Core 1 i386 and CentOS 4.2 x86_64.

Since  has been  for a week, Google was  its new version yesterday. GWT is now so popular. Anyway, I don’t like to program in Java. Now, there is a serious effort to reverse engineer GWT to make a clone in Python for Python fans like me. In beginning, it named as py-gwt but now it has been changed to pyjamas and it’s alive. Let’s see how it looks like at the real code in subversion repository.

According to announcement, I have upgraded all drupal sites in my control to 4.7.1 with just one command as follow. Fortunately, I checked out Drupal source from the CVS repository directly so I can synchronize so easy.
