Cython tutorial slides

[Stefan Behnel]

Hi,

I just uploaded the slides from a recent tutorial talk I gave about Cython.

Have fun,

Stefan

Thanks, looks very nice. In particular I enjoyed the graphics of Cython
vs. Python and C/Fortran/...

Could you add a link together with the event where this talk was held on

wiki.cython.org/talks

?

Very nice -- thanks for posting.

I took the opportunity to try out the --embed feature, and ran your
example. There's a small typo; I post it here in case you want to fix
it for future versions:

Traceback (most recent call last):
File "hw.py", line 6, in hw (hw.c:613)
hello_world()
File "hw.py", line 3, in hw.hello_world (hw.c:456)
print "Welcome to Python %d.%d!" % sys.version_info()[:2]
TypeError: 'tuple' object is not callable

Fixing it is trivial, of course.

Thanks again!

Ah, yes, I always mix up sys.exc_info() and sys.version_info...

Thanks!

They are written in reStructedText and converted to the S5 presentation
tool using "rst2s5", which comes with docutils. The syntax highlighting
uses Pygments, which has Cython support since V1.1.

http://meyerweb.com/eric/tools/s5/
http://docutils.sourceforge.net/docs/user/slide-shows.html
http://pygments.org/

ReST and S5 provide a wonderful separation of content and presentation.
When you look at the slides, watch out for the control bar in the bottom
right corner, and also try pressing "t".

As an example, here's the ReST source of another presentation I gave:

http://codespeak.net/svn/lxml/trunk/doc/s5/lxml-ep2008.txt

I really like how clean and readable it is even as plain text source.

Yep, I actually think the size of the orange bubble isn't even that
exaggerated. Cython really opens up a huge space to put the tradeoff
between speed and simplicity.

Done. I also added links to the workshops/conferences.
