With my searches concerning different concepts/technologies of the Java software development (e.g.: Design Patterns, JSP, SOAP, JUnit, SQL, Apache Tomcat) I am encountered in the last 3 months some interesting sides in the Internet. I put these down in Software-development. I used the Apache, JSP and SQL sides as tutorial for the JSP-MemCounter. Concerning the Design Patterns to me it was noticeable that although I did not have deeper knowledge of these, nevertheless i already used some in projects (e.g. the Thesis (diploma): Multimedia algorithms and datastructure assessments (MA&DA)). So e.g. the singleton and the observer pattern. The moreover I put down under Tools: Freeware many links according to useful freeware programs, which I use partially on my computer.
