[pypy-dev] Numpy Topics

[Steven Jackson]

Thank you for your responses; I'm pretty sure I can do quicksort,
mergesort, and heapsort. :)
Also, I did see responses starting in the minute after I decided to send an
email, so I think I'm good on the IRC front.

Am I right in assuming that I should checkout "default," make my own
branch, write failing test cases, make the test cases succeed (occasionally
merging in default) and then... actually i don't know what then. Commit?
Pull request? I've never worked on a large project under version control
and "Getting Started Developing with Pypy" "How to contribute to Pypy" and
"You want to help with Pypy, now what?" all seem to assume prior knowledge
about version control in general. Can anyone point me to a resource that
can help me understand the development cycle?
