that is right across the highest point in Bristol:
We had a presentation by Gregory Bard:
Then we had a discussion what things should be done in the following coding sprints. Then we coded and in the afternoon I had a presentation "SymPy: A Python library for symbolic mathematics".
In the morning Michael Abshoff gave a presentation about valgrinding a Python/Cython/C/C++ library application like Sage (which adds complexity and its own set of problems because of python).
