Miscellaneous

On this page I collect various lessons learned, or other encounters with technology which may be of interest to others…

  • Bad Performance – Meaningful assessment of response-time dataThis post references an article I published on how to efficiently assess response time data, establish clusters of service response times, recognize trends, and tips on what to do with the information identified. For all of those who want to read it, the article is available in German and print only. 
  • Lesson Learned: Using an Apache Derby Embedded database with Google Web ToolkitApache Derby can be integrated with Google Web Toolkit. It requires, however, a few tricks. This short post outlines the troubles ( java.lang.ClassNotFoundException, java.lang.NoClassDefFoundError: java.io.FileOutputStream, and java.lang.NoSuchMethodError: org.mortbay.thread.Timeout.(Ljava/lang/Object;)V) I ran into, and how I overcame them. I created this post to put the information into one place, as it took me a few hours to piece it together from bits and pieces scattered across the web. I hope it helps.
