Extending Python as a language has always been among the main objectives of the
Python core development team. Enhancing Python and developing the CPython runtime
have become interchangeable activities. Those who tried to extend Python had to be
core developers of CPython or at least experimenting with one of the alternative
runtime environments like PyPy, IronPython or Jython. For those...

After years of decline, object databases are now becoming more and more important
again because of new open source systems. Their data objects directly appear as
programming language objects without any mapping - avoiding the impedance mismatch
between objects and relational tables.
Most object databases are designed to work well with languages such as Java, C# or
C++. This talk covers...
