Wrapping Up Google Summer of Code

My Summer has been over for a while, but GSoC is officially ending this week. And what do I have to show?

• SciPy's sparse matrices now support boolean data.
• Sparse matrices now support boolean operations (!=, <=, etc.).
• NumPy universal functions (ufuncs) can now be overridden for compatibility.
• Sparse matrices uses this ufunc override functionality to do sensible things when acted on by ufuncs.
• Support fancy indexing.
• Axis arguments for min and max methods.
• various other things: speed ups, small features, test coverage, bugs fixes, code clean ups, and a few backports.

But I think that I have benefited personally from this experience much more than SciPy has. I learned so much this summer, a short list of things I know vastly more about than I did before this summer:

• PYTHON. Jeez looking at code I wrote before this summer is painful.
• The Python and NumPy C API, before this summer I was a total C noob. Now I can scratch together a python API in C.
• SciPy.
• NumPy, numpy.frompyfunc is awesome.
• Git, before this summer I could commit thing to my own repos and that was pretty much it. Git hooks are awesome.
• In general, development workflow.

I grown attached to SciPy and am excited I can make meaningful contributions to that are actually helping people. But contributing more will have to wait untill after the GRE, grad school applications, and my senior thesis. There are a few things I would like to add down the road to incorporate into SciPy 1.0. e.g. 64bit indices, change spares matrices to emulate numpy.array rather than numpy.matrix. I would also like to see if I can apply ufunc overrides in a few other places that mix numpy.array and scipy.sparse like scikit-learn.

Here is a link to git log -p upstream/master --author="Blake Griffith" in numpy and scipy.
