[SciPy-User] [ANN] For SF Bay Area residents: a discussion with Guido at the Berkeley Py4Science seminar
Fernando Perez
if you reside in the San Francisco Bay Area, you may be interested in
a meeting we'll be having tomorrow November 4 (2-4 pm), as part of our
regular py4science meeting series. Guido van Rossum, the creator of
the Python language, will visit for a session where we will first do a
very rapid overview of a number of scientific projects that use Python
(in a lightning talk format) and then we will have an open discussion
with Guido with hopefully interesting questions going in both
directions. The meeting is open to all, bring your questions!
More details on this seminar series (including location) can be found here:

Cheers,
f

Attendance was excellent (standing room only, and I saw some people
leave because it was too full). Many thanks to all the presenters!

From the silent majority who lurk here, many thanks to you Fernando for
setting this up (and for IPython). It is wonderful to know that the
concerns and achievements of scientific computing in Python are on the
radar of the group of people responsible for leading the language. If
you have thoughts on how the wider community can contribute to this sort
of communication in the future, please share.

Yes, thank you Fernando. If you are at liberty to comment further on
discussions concerning parallel computing and the GIL, I would be very
interested to hear about it.

Sorry for the dumb question (but some of you know me by now !). I was
able to stumble around and solve a differential equation I was working
on in terms of Weierstrass elliptic functions (though an open source
type of guy I have to thank Wolfram re. wloframalpha for help with
that...). I'd like to evaluate the function for various sets of
parameters and found that the special functions package for scipy has
Jacobi elliptic functions available. I seem to recall that the
Weierstrass elliptic functions are special cases of the Jacobi elliptic
functions but haven't been able to locate any source that describes that
in any detail. Anyone have any hints ? Thanks,

I haven't checked.. you might try the books of Apostol (mathematical
analysis), Courant and John, or Numerical recipes on this.

series.sum() gives this error whereas series.data.sum() works.

I don't get this error when trying a sum on a TimeSeries object. I noticed you
are using an older version of the timeseries module. Can you try upgrading to
the latest version and see if you still get an error? Also, if you still get
the error please post a small example demonstrating how to get the error,
thanks.
Also, note that we will probably be doing a new minor bug fix release within
the next week or two.

actually i figured that out it throws that error when data array is of dtype object
In [74]: data = npy.array([-1840.0,-1550.0,-940.0,2660.0,190.0,3980.0,1130.0,2090.0,1980.0,1220.0,-1220.0,1140.0,-2420.0,2200.0,370.0,230.0,-60.0,2550.0,970.0,660.0,-20.0,50.0,-980.0,6580.0,4090.0,3240.0,-350.0,-1800.0,2020.0,5050.0,-110.0,-330.0,-2290.0], dtype=npy.object)

Confirmed. The bug is in numpy.ma, I'll check that later this evening...
