Hey I'd like to know if the proposed numpy projects list at
https://bitbucket.org/pypy/extradoc/src/extradoc/planning/micronumpy.txt
is still up to date, and if so what is meant by "a good sort function."
If it's just a matter of implementing a known good algorithm, that
seems like a good way to start contributing to pypy.
The advice on http://doc.pypy.org/en/latest/project-ideas.html
suggested posting this question to #pypy on IRC, which I attempted to
do through http://webchat.freenode.net/ but I never got a response. It
was my first time trying to communicate over IRC, so I'm not sure if I
did something incorrectly while trying to join the channel (I saw
buildbot messages but no one else speaking) or if the lack of activity
was simply due to time difference (I'm on USA east coast time, while
I'm aware that much of the pypy-dev community is located in Europe).
Any help with either the original question or joining the IRC
discussion would be greatly appreciated :)

The list is not really up to date, IRC is a good place to get more info
but it is a low-activity channel with most devs online during European
day-evening, and not every day.
As for sort, we have implemented only timsort for ndarrays of numeric
types, not record arrays. Numpy supports ‘quicksort’, ‘mergesort’, and
‘heapsort’, timsort is not supported. So to be numpy-compatible we
should maybe support the other kinds, and support sorting record arrays.
It would be great to get more people involved in pypy-numpy.
