Subject: [CentralOH] Monthly Meeting -- March 27
Message-ID: <CAJzarMPZA6Yx6Ub+TUUX0gcdGwxVToxVW7dESE2_v33AQiYHWg@mail.gmail.com>

Come and learn, share, grow, meet new people, and visit old friends at our
monthly meeting! We'll be talking about the Python programming language and
anything that intersects it, and the cool stuff you can do with it.

Our next monthly meeting will be March 27, 2017, at Pillar (as always).

RSVP Here:
https://www.meetup.com/Central-Ohio-Python-Users-Group/events/236712418/

Max Morlocke will be presenting this month on Memory Leak Troubleshooting.

Memory leaks are are painful.  We as developers are encountering a
situation where garbage collection isn't working as we would like and
instead we are suffering from a situation where memory is constantly
growing, potentially resulting in watchdog processes killing processes.
Further, memory leak troubleshooting in python can be frustrating, tools
are not necessarily as friendly as on platforms like Java and .NET.  In
this session, we'll go over what a memory leak is, what some common
symptoms are, and some common tools to troubleshoot.  We'll also go over
best practices to minimize the chance of a memory leak occurring and how to
make it easier to find out what's happening inside your code well before
watchdog starts shooting your production applications in the head.

Then, Jim Prior will give a presentation on using named groups in regular
expressions. From "The Zen of Python":

    Readability counts.

Named groups makes groups within regular expressions more readable and also
make the reference to groups more readable.

Afterwards we'll be heading to Brazenhead on 5th.

Subject: [CentralOH] PyOhio 2017 -- be a part of our 10th anniversary
Message-ID: <CAJzarMOYTB5Kr7WM8K8ev1XqfYW5DHpOEQAiXNN3enxtR61R=w@mail.gmail.com>

PyOhio is special to me -- it's where I gave my first talk. PyOhio is
special because you can attend for free, and we've reached out to and
helped many who didn't have or couldn't spend hundreds of dollars on a
conference to jump start or improve their career in programming.

But while all of us are volunteers, and we have an amazing partnership with
the Open Source Club at OSU to help keep costs low, PyOhio does cost money
to put on. The last three years our expenses have been about $25,000 per
year. That's about $60 per attendee.

The bottom line: *We need sponsors!*

If you work at a company, or know of a company, or have a philanthropic
relative, please let them know that sponsoring PyOhio gets their message
out to nearly 500 motivated developers who care enough about programming to
give up their Saturday and Sunday to attend.

If you are reading this, could you please:


1. Ask one company to sponsor PyOhio (http://pyohio.org/sponsors/prospectus/
)

2. Forward this email to someone who know at a company that would benefit
from sponsoring PyOhio.

3. Introduce me (Eric Floehr) to someone who might sponsor or donate to
PyOhio.


Thanks so much for your help in making the 10th PyOhio it's best yet!

Cheers,
Eric Floehr
Sponsorship Chair & Treasurer
PyOhio 2017

Subject: [CentralOH] 'git gui','swig', and Tk under Python3
Message-ID: <alpine.LRH.2.03.1703301204420.1421@bjyevire.pbz>


Jim Prior and I were discussing approaches to Python this 
morning, and I mentioned a couple of 'dark corners' of which 
he was unaware

1. 'git' has a GUI available (packaged separately on CentOS 7, 
but part of the 'within the four corners of the base' 
mainstream there nonetheless

2. And a conversion tool which includes Python code as a 
target to emit: swig

from: rpm -qi swig

URL         : http://swig.sourceforge.net/

Summary : Connects C/C++/Objective C to some high-level 
programming languages 

Description : Simplified Wrapper and Interface Generator 
(SWIG) is a software development tool for connecting C, C++ 
and Objective C programs with a variety of high-level 
programming languages.  SWIG is primarily used with Perl, 
Python and Tcl/TK, but it has also been extended to Java, 
Eiffel and Guile. SWIG is normally used to create high-level 
interpreted programming environments, systems integration, and 
as a tool for building user interfaces

3. and a separate -doc sub-package as well

I've been building Python user facing tool widgets for an 'all 
three platforms' and report that the Tk based GUI tools work 
'just fine' under Python 3

Subject: [CentralOH] Interactive Brokers are running a webinar on their new
 Python API
Message-ID: <alpine.LRH.2.03.1703301155020.1421@bjyevire.pbz>


IB are running a free (Webex delivered) webinar on the new 
python API 18th April 12:00 EST if any one is interested

You can sign up via the IB site API tab 
from?
	https://www.interactivebrokers.com/en/index.php?f=2226

Note that an interested participant would need to select the 
API tab, as there is not a direct link

Duration: 	1 hour 30 minutes	Description: 	

1) Capabilities and requirements of the TWS API

2) API architecture and general programming considerations

3) Basic flow of an API program as demonstrated by the IB 
sample Program.py

4) Current API reference guide documenting API Latest (v973)

5) Demonstration of common API tasks in Python - receiving 
market data, performing Financial Advisor specific operations

================

The mentioned Python code is at:
	http://gallery.herrold.com/stuff/Program.py

but the full git repository is under a request by IB as to 
general access, where one needs to request such (and it is 
freely given)  As one can see the code is NOT FOSS, but rather 
under different licensing terms

More as to meeting with Jim Prior:

I mentioned the IB Python client a moment ago, and part of my 
regimen as a developer, is a 'cron' based 'pull' of an 
upstream against which I do not have direct commit rights.  
This produces an email to me, to see 'what happened on the 
overights'

Here is a sample email.  The Pythonic part of merge was one of 
which I was aware that had not yet upstreamed, extending a new 
feature into the mainline code.  The code itself is kind of a 
pretty demonstration of how simple an extension is, in what is 
a rather old (over a decade of legacy code to support) and 
rather fat and 'hard to get a grip on' codebase [The IB TWS 
API is a very complex model, with Pub/Sub, as well as one-off 
ad hoc queries, on any of a hundred different trading 
exchanges, and literally every security which might be or was 
traded in a financial market]
