Well, to say the truth none of both ;-). The truth is that I was trying to
accelerate some parts of my software and realized that numarray was an
important bottleneck. NumPy was already in advanced beta stage and some small
benchmarks conviced me that it would be the solution. So, I started porting
one single C extension (PyTables has several), the simplest one, and checked
that the results were correct (and confirmed that the new code was much
faster!). After that, the second extension came converted and I'm in the
process of checking everything. Now, there remains 3 more extensions to
migrate, but the important ones for me are done.
So, no plans other than having a good motivation (and the need for speed was a
very good one). However, I think that having a complete test suite checking
every detail of your software was key. Also, having access to the excellent
book by Travis was extremely helpful. Finally, having IPython opened to check
everything, look at online docstrings and be able to do fast timings added
the "cerise sur le gâteau".
Luck!
