Can you give us a synopsis? or point us to when exactly in the clip we're 
supposed to listen?

Er, I didn't listen to the whole thing, but there are some references
to numpy being difficult to install under platforms other than windows
(arguable I guess), I got the impression the speaker was conflating
the enthon distribution with scipy, and he says at one point that
numarray is the successor to numpy.   Not fud exactly, but a bit
misleading.

I googled fud and found two definitions: "fear, uncertainty and doubt," 
and "frustrate, undermine, and demoralize" - which is intended?

I listened to this and it looks like Sergio Ray is giving an intro class 
on scientific computing with Python and has some concepts confused.   We 
should take this as a sign that we need to keep doing a good job of 
educating people.

Here are some things he has confused:

NumPy == Numeric

He tells his class that numarray is going to replace NumPy


SciPy == Enthon

He thinks that the Enthon distribution *is* SciPy.  So, he tells his 
class that SciPy is "hard to use" on Unix because the Enthon 
distribution isn't available for Unix.


I'm not sure when this recording was done but it was released on Python 
411 at the end of May and he mentions this years SciPy conference with 
Guido as the key-note speaker so it was within the past few months.

Other than that it has some good introductory material on what the Num* 
packages provide to Python.

All I can say is, if someone that confused about basic facts is being 
cited as an authority and teaching a podcast class, I'm glad I have 
someone on-site at my work who actually knows what they're talking about 
and not relying on the Net for my numpy education.

Oh dear, I hope my friends remind me never to let anyone record what I
say when I give a class!

The numpy == Numeric confusion is understandable. Numeric Python (AKA 
Numeric) was typically referred to as NumPy even though the name of the 
module was actually Numeric. So, in a sense numarray was a replacement 
for (the old) NumPy, and numpy is a replacement for both the old NumPy 
and numarray. At least I sure hope so!

I'm on UTC+02:00 so only just saw there have been a few posts. Basically my
issue was with numarray going to replace NumPy, and that the recording was
only a few months old, sitting on the web where newcomers to Python will
undoubtedly find it.

I thought the proper thing to do would be to ask the 411 site to just 
append a footnote explaining that some of the info is out-dated. I just
didn't want to do it without getting the groups opinion first.

Regards, Louis.
