Dear all,

One recurring question is how to *grow the contributor base* to NumPy and provide help and relief to core developers and maintainers.

One way to do this would be to *leverage the upcoming SciPy conference*in 2 ways:

1. Provide an intermediate or advanced level tutorial on NumPy focusing on teaching the C-API and the architecture of the package to help people navigate the source code, and find answers to precise deep questions. I think that many users would be interested in being better able to understand the underlayers to become powerful users (and contributors if they want to).

2. Organize a Numpy sprint to leverage all this freshly graduated students apply what they learned to tackle some of the work under the guidance of core developers.

This would be a great occasion to share and grow knowledge that is fundamental to our community. And the fact that the underlayers are in C is fine IMHO: SciPy is about scientific programming in Python and that is done with a lot of C.

*Thoughts? Anyone interested in leading a tutorial (can be a team of people)? Anyone willing to coordinate the sprint? Who would be willing to be present and help during the sprint? *

First thought: excellent initiative. I'm not going to be at SciPy, but I'm happy to coordinate a numpy/scipy sprint at EuroScipy. Going to email the organizers right now.

The EuroScipy organizers have accepted our sprint, so we'll have a room available. If you're going to the conference, think about reserving Sun 25 Aug to attend this sprint. I've put up a page where people can add topics and more details: http://projects.scipy.org/scipy/wiki/EuroSciPy2013Sprint Ralf

Note that there is less than 1 week left until the tutorial submission deadline. I am happy to help brainstorm on this to make it happen.

Thanks, Jonathan and Andy, for the SciPy2013 organizers

Awesome Ralf!

And thanks David C. for being available for the US one. When you say you would like to be part of it, did you mean an advanced tutorial or a sprint?

I meant I would be happy to contribute to a tutorial in the spirit of "dive into numpy code". I would prefer if we were two doing it, though. David

That's awesome. I'm definitely one of the targeted audience. Thanks. On Sun, Apr 7, 2013 at 5:40 PM, David Cournapeau wrote:

I have prepared a preliminary proposal https://github.com/enthought/davidc-scipy-2013/blob/master/proposal.rst

Roughly, after ensuring everybody knows how to build numpy from sources in a dev-friendly way, I was thinking about - describing the source code tree organization - talk about the main data structures (array + dtype), and how they relate to the python runtime - more details about dtype: use basic array operations to describe the whole mechanism, and how to create a simple one (using wrapping float128 as an example)

I also intended to give a few tips regarding tools (e.g. how to track a python call to its core C implementation).

Stéfan Van Der Walt agreed in principle to contribute, but his participation is still very conditional.
