Pandas dev sprint July 5-8 (pre-Scipy Conf)
by Joris Van den Bossche June 12, 2018

June 12, 2018

Dear all, We are planning to do a pandas sprint just before the Scipy Conference (which is in Austin, Texas, July 9-13). The sprint would then be from July 5 or 6 to July 8, also in Austin. We will meet there with some of the core devs, but we also want to invite other pandas (or related libraries) contributors. Note: the sprint is not meant to jump-start newcomers to contributing to open source (for that, there is a sprint at the end of the Scipy). The exact planning of the sprint still needs to be discussed (will open a separate thread for that), but topics will probably include: general issue clean-up, discussing project management, roadmap to pandas 1.0 (what do we still want to get in / change before that) and evolution of pandas afterwards, ... and of course actual coding. *So if you are interested, certainly let something know! * We probably want to keep it somewhat limited in number, but don't hesitate to state your interest. If you would like to participate, but not sure if you would fit at such a sprint, don't hesitate to mail me personally. If you would like to participate, but would need financial support, you can also mail me (we might have some funds, but not fully sure yet). Best, Joris

Agenda for pre-Scipy Pandas dev sprint
by Joris Van den Bossche May 22, 2018

May 22, 2018

Hi all, As I mailed before to this list, we are holding a pandas dev sprint just before Scipy (see https://mail.python.org/pipermail/pandas-dev/2018- April/000739.html, still welcome to contact me if you are interested in attending). But so we should also prepare in advance what we actually want to do and discuss during the sprint. Therefore I started a shared document: https://docs.google.com/document/d/ 1CPkc4avxb9XiEpI7Zz9Wg8FUkC_oXQqmdZzD-alCa7o/edit?usp=sharing, and added some (very brief) ideas. Feel free to add things there, add comments or discuss here on the mailing list. It would be good to get this document much more detailed, so we can use that as a start to discuss things during the sprint itself, and to give people that cannot attend also a chance to comment. Joris
