+# 2019-08-28 NumPy Development Meeting
+
+- Time: 11am Pacific Time
+- Join via Zoom at https://berkeley.zoom.us/j/762261535
+- [Trello workboard](https://trello.com/b/Azg4fYZH/numpy-at-bids)
+- [Previous meetings](https://github.com/BIDS-numpy/docs/tree/master/status_meetings)
+
+**Present:** Matti, Stefan, Tyler, Hameer, Inessa, Warren, Ralf, Sebastian, ZJ
+
+## Follow-up from last meeting / discussions
+- Move multibuild to MacPython and change its name
+  Matti is now a maintainer on the multibuild repo
+  - move numpy-wheels to the numpy organization
+  - move wheel builds [to azure from appveyor](https://github.com/MacPython/numpy-wheels/pull/60)
+    Stopped work on this until after the current release cycle
+
+- 1.17.1 and 1.16.5 released!! Documentation at https://numpy.org/doc not updated yet.
+
+- Add a ci-tests-requirements.txt and use it in the CI system. [Working PR](https://github.com/numpy/numpy/pull/14378). Needs a bit of guidance
+
+- Possible NumPy developer weekend: Nov 22-23 maybe move it back to the weekdays before that? Some of the documentation team may join.
+
+- Inaugural NumPy Community Survey (see section below for details)
+  - translation to other languages: Zj Poh volunteered.
+
+# Topics
+
+- Refresh the admins of the github [numpy organization admins](https://github.com/orgs/numpy/teams/owners-legacy)
+- Rackspace [wheels](https://7933911d6844c6c53a7d-47bd50c35cd79bd838daf386af554a83.ssl.cf2.rackcdn.com/) and [openblas](https://3f23b170c54c2533c070-1c8a9b3114517dc5fe17b7c3f8c63a43.ssl.cf2.rackcdn.com/) uploads.
+  - Matthew Brett has the unencrypted key. Does anyone else?
+    - Should be part of the private repo for NumPy management.
+  - we should upload arm and powerpc OpenBLAS to there as well (currently on DroBox since Tyler builds them)
+
+- our [information at nabble](http://numpy-discussion.10968.n7.nabble.com/) is outdated. The [admins](http://numpy-discussion.10968.n7.nabble.com/template/NamlServlet.jtp?macro=app_people&node=2&filter=Administrators) can change it, does anyone know who Timmie and Israel are?
+    - Maybe try the "send email to" link on their user pages (mattip tried that, "Timmie" seems to be Tim Michelsen?, could not get info on "Israel")?
+
+- Private vs. public submodules in namespace, we're continuing to just add random public-looking things, it's a bit of a mess. What do we do?
+    - For `numpy.random` see e.g. [gh-14360](https://github.com/numpy/numpy/pull/14360)
+    - Another example: `dir(np.lib.mixins)`
+    - We should add a test that hardcodes the current namespace, and will fail if anything is added without a PR.
+    - Polynomial namespace, multiple ways of calling the poly functions; Eric Wieser has a [suggestion](https://github.com/numpy/numpy/pull/13601#issuecomment-525591808) on how to fix
+
+- Open PRs, waiting for review/merge:
+  - ship our own [numpy.pxd](https://github.com/numpy/numpy/pull/12284)
+  - [use a release summary instead of a wall of text](https://github.com/numpy/numpy/pull/13886)
+
+- Nep [website](https://numpy.org/neps) not updating from [repo](https://github.com/numpy/neps), Nep 29 not appearing
+  - NEP 30 is showing up, so something is broken with NEP 29?
+
+- Hameer proposed NEP 31: [Context-local and global overrides of the NumPy API](https://github.com/numpy/numpy/pull/14389/files)
+
+
+### Inaugural NumPy Community Survey
+GitHub repo: github.com/numpy/numpy-surveys
+
+Proposal
+github.com/numpy/numpy-surveys/blob/master/NumPy-survey-proposal.md
+
+Topics Overview
+https://github.com/numpy/numpy-surveys/blob/master/NumPy-survey-topics.md
+
+Questionnaire Draft
+https://github.com/numpy/numpy-surveys/blob/master/NumPy-survey-questionnaire.md
+
+This survey shall have up to 40 questions, mainly close-ended to allow easy processing, and take 5-10 minutes to complete.
+
+All NumPy community members are invited to contribute to the creation and selection of questions by submitting pull requests against the [`numpy-surveys` repo](github.com/numpy/numpy-surveys).
+
+## Additional Details
+
+- Matti
+  - [cython `@property` decorator](https://github.com/cython/cython/pull/3095), seems to work but needs a refactor
+  - reviving dtype allocation and initialization changes in preparation for Sebastian's larger refactoring
+  - preparing a [talk](https://github.com/BIDS-numpy/docs/blob/scipy-europe-2019/presentations/inside_numpy_talk_scipy2019.pptx) for EuroSciPy Sept 5 based on Ralf's SciPy talk and a ctypes, cffi, Cython [tutorial](https://github.com/mattip/c_from_python)
+
+- Sebastian
+    - [Extensible Datatypes for NumPy](https://hackmd.io/kxuh15QGSjueEKft5SaMug) is pretty far along (good to read through, details probably missing, but some of them might still be in flux). Start to change the basics in NumPy: https://github.com/seberg/numpy/tree/dtypemeta (alpha, trying a few different approaches). Inserting dtype classes works.
+        - Next step: wrapping new slots with legacy compatible versions (implement a basic CastingImpl).
+        - Redirect current API functions to use new slots (old API functions may be renamed and used as fallbacks for compatibility slot implementations).
+    - Slight issue: ABI compatibility of ``PyArray_DescrCheck``, but we can backport a fix to old numpy versions (So compiling with an updated old version of numpy would work).
+    - Got lost in Dynamically created Type Objects, so for now "malloc" them and use the typical "static" python API (this seems OK for legacy wrapping, but not ideal?).
+
+- Warren
+    - Old pull request triage: closed some abandoned PRs, pinged devs on others., push for close or complete.
+    - Bug fix for histogram.
+    - Restarted conversation about deprecating the financial functions.
+    - Updated PR for the multivariate hypergeometric distribution, waiting for review.
+    - Started reviewing ufunc code, and worked on improving the internal code documentation in generate_umath.py.
+    - Catch up on Sebastian's NEP / dtype work
+
