Subject: [CentralOH] PyOhio: Proposal deadline in 5 days
Message-ID: <i2p34f468871005050526zd78a1859kad0a9d45b3c0e9d@mail.gmail.com>

Hey everyone,

I just wanted to remind you that the deadline for submitting proposals
for PyOhio is coming up in 5 days.  If you are thinking of submitting
a talk, tutorial, or panel proposal, please get going on it!

There are many benefits to talking, doing a tutorial, or moderating a
panel discussion:

1. It's a great chance to practice public speaking in front of a
receptive audience.

2. It's an awesome addition to your resume.

3. Doing it forces you to learn your topic more than you would
otherwise...it's a great motivator.

4. You will gain the respect and admiration of your peers.


But in addition to the benefits you will accrue from doing this, you
will also be greatly benefiting others by sharing your knowledge and
helping others grow as Python developers.


So please don't delay...submit your proposal TODAY!

Best Regards,
Eric

Subject: [CentralOH] audience-instructors for Python bugfixing needed
Message-ID: <p2y6523e39a1005060640p31902c04i46ce4d24fd4c29f9@mail.gmail.com>

Calling... anybody who has experience with working on Python itself!  (The
Python core, and/or the Python Standard Library)

I need a few of you (3?) who can commit to come to PyOhio and take part as
audience/instructors in a Teach Me Bugfixing session.  The PyOhio Call for
Proposals is up May 10 so I'd better find you quick!

Our awesome language has a problem: there's a big backlog of bugs in the
Python bug tracker, and the volunteers who work on them are stretched too
thin.  That's why Jesse Noller and others are trying to get more people
involved in the process.  (Read
http://jessenoller.com/2010/04/22/why-arent-you-contributing-to-python/)

I've never done it myself, so I want to lead a Teach Me Bugfixing session.
(See http://catherinedevlin.blogspot.com/2010/04/bugfixing-at-pyohio.html.)
In a Teach Me session, the person at the projector *doesn't* know the
material.  Instead, she asks the audience questions ("How do I find a bug to
work on?"), and they talk her through it.  It's based on Teach Me Twisted, a
mind-blowing session Steve Holden led at PyCon 2008 (
http://catherinedevlin.blogspot.com/2008/03/teach-me-twisted.html).  I think
it's a fantastic way to teach, but it depends on some veterans being in the
audience.  There are folks in the greater Python community eager to get hold
of a video of such a session... if we do this well, it could become an
important tool in keeping the quality of core Python code high.

And all I need from you, my audience-instructors, is a promise to show up
(no preparation necessary).  Can you make it?  Can you pass the appeal on to
others you know of?

Thanks!  See you in July!

Subject: [CentralOH] Python Miro Community
Message-ID: <005c01caf11e$5d019c60$1704d520$@com>

 

I highly recommend this site.  Pycon 2009 and 2010 are represented, as well
as Django conferences. 

 

http://python.mirocommunity.org/

 

The videos on the python miro community cover a wide range of topics, and
are quite well organized. Recently I watched videos on matplotlib, design
patterns in Python (Martelli), advanced python (Holden) and cmd interfacing
(our very own Catherine).

 

http://python.mirocommunity.org/video/1533/pycon-2010-easy-command-line-a

 

I found the videos by Holden and Martelli to like you're really in class.

Subject: [CentralOH] Monday's Meeting
Message-ID: <AANLkTimgzzjcx19Opad1EB1ZgrGrus3jS1TELiY5RKVv@mail.gmail.com>

All,

I think this Hands-On Python is really going to be cool...in
preparation for that you'll definitely need to bring you laptop!

Additionally, in order to get the most out of the meeting, you'll want
to have installed:

All talks:
Python 2.4 or 2.6

For the SQLAlchemy talk:
SQLAlchemy
Python sqllite (2.4 only, 2.6 is built-in)

For the Networking talk:
Telnet Client

For the X Windows/dmenu talk:
python-xlib (X library for Python) (Note, Windows users will just have
to watch or buddy up)


See you there!
Eric

All,

I apologize for being so delinquent in publishing the files from the
April COhPy meeting.  This gzipped tar-ball contains all the files for
OCLC's implementation of map-reduce.  Let me know if you have any
problems with the download or the file.
