[Numpy-discussion] PyData Madrid

[Jaime Fernández del Río]

Hi all,

I just found out there is a PyData Madrid happening in early April, and it
would feel wrong not to go, it being my hometown and all.

Aside from the usual "Who else is going? We should meet!" I was also
thinking of submitting a proposal for a talk. My idea was to put something
together on "The future of NumPy indexing" and use it as an opportunity to
raise awareness and hopefully gather feedback from users on the proposed
changes, in sort of a "if the mountain won't come to Muhammad" type of
thing.

Thoughts? Comments? Anyone else going or thinking about going?

I guess you do know my last name means mountain in german? But if
Muhammed might come, I should really improve my arabic ;).

In any case sounds good to me if you like to do it, I don't think I
will go, though it sounds nice.
There are probably some other bigger things for "the future of NumPy",
both impact and work wise. Such as the dtypes ideas, which might be
nice to mention on such an occasion.

Of course I like feedback on indexing, though (not sure if your ideas
for indexing go further then what I think of right now). That NEP and
code is sitting there after all with a decent chunk done and pretty
much working (though relatively far from finished with testing and
subclasses). Plus we have to make sure we get the details right, and
there a talk may really help too :).

Sounds like a good idea to me too. I like both the concrete topic, as
well as just having a talk on Numpy at a PyData conference. In general
there are too few (if any) talks on Numpy and other core libraries at
PyData and Scipy confs I think.

+1.
It would be great a numpy talk from a core developer. BTW, C4P closes
tomorrow!!!
Jaime, if you come to Madrid you know you have some beers waiting for you.
Disclaimer, I'm one of co-organizers of the PyData Madrid.

Since when does one need disclaimer when offering beers ? That would make
for a dangerous precedent :)

The disclaimer is not for the beers :-P

The beers sentence should be a "P.D.:"

Best.

With a full day to spare, I have submitted a talk proposal:

Brief Description
Advanced (a.k.a. "fancy") indexing is one of NumPy's greatest features.
It is also well known for its ability to trip and confuse beginners and
experts alike. This talk will review how it works and why it is great,
give some insight on why it is how it is, explore some of its darkest
corners, and go over some recent proposals to rationalize it.

Detailed Abstract
Advanced (a.k.a. _fancy_) indexing is one of NumPy's greatest features.
Once past the rather steep learning curve, it enables a very expressive
and powerful syntax, and makes coding a wide range of complex operations
a breeze. But this versatility comes with a dark side of surprising
results for some seemingly simple cases, and conflicts with the design
choices of more recent data analysis packages. This has led to a
viewpoint with growing support among the community that fancy indexing
may be too fancy for its own good. This talk will review the workings of
advanced indexing, highlighting where it excels, and where it falls
short, and give some context on the logic behind some design decisions.
It will also cover the existing
[NumPy Enhancement Proposal (NEP)](https://github.com/numpy/numpy/pull/6256)
to "implement an intuitive and fully featured advanced indexing."

Jaime, if you come to Madrid you know you have some beers waiting for you.

Talk or not, I'm really looking forward to those beers and getting to meet
Juan Luis and you!
