Hello BangPypers,

As you all know, PyCon India 2018 is the 10th edition of PyCon India.
We are planning to bring back PyCon India 2018 back to Bangalore
again, (possibly NIMHANS).

In order to execute the same, we need your support. Before announcing the
same
in Inpycon mailing list, we need to form an organizing team so that we can
work together to put a proposal out.

Those who are interested in the same, feel free to reply to this email.
If any queries, feel free to ask.

Thanks,

Re: [BangPypers] generating cisco config using templates?

[sayantan bhattacharya]

Can you please specify what configuration you are trying to generate? Are
you trying to configure multiple devices?

If yes, you can try using the Ansible module, provided you aim for
configuring devices issuing the master slave model.

Re: [BangPypers] Online communication channel

[sayantan bhattacharya]

I have not used Slack, but here's an idea that I have. We could always
create a custom python module enabling us to have all the functionalities
mentioned by Krace. This will in itself become an Open Source contribution
as well as can be attributed to 10 years of Bangpypers(an open source
framework made for group communication).

I am not sure if one exists, but if it doesn't we can obviously start.

Re: [BangPypers] Connecting developers and companies

[sayantan bhattacharya]

Going through the mails, I think it would be better for us to maintain a
job posting site/place separately. Personally, I like the meet-ups for the
information they provide as well as chatting with other programmers.
Allowing companies/startups to present their content would not fit the
actual purpose of the meet ups. But, there's the portion of companies
allowing us to meet at their locations, to which we can allow the hosting
company to present their content as compared to allowing other companies to
come up too.

For example, Company A is hosting our meet-up, so by default Company A gets
the chance to place their content, availing this chance will be at the sole
disposal of Company A. But in case Company B wishes to present too, they
will have to get prior permission from Company A along with the organizers
of the meet-up.

 No, its volunteering. Even speaks give their time and share knowledge. They
 are not incentivised either.
 Informal conversations between whoever are interested are not an issue.

Re: [BangPypers] Python is still greek to india's top IT firms

[sayantan bhattacharya]

Hello all,

I work at TCS and they didn't know about Python either. Now that I have
written a script that does the log monitoring easy for the Application
support guys, they have accepted the language. But there seems to be a
resistance among the people using Java to accept that Python is powerful
and capable enough to do the same task that Java does.

 NEW DELHI: Recently, one of India's top software companies was faced with
 quandary. It had won a $200 million (Rs 1,200 crore) contract to develop an
 app store for a large US bank, but did not have adequate numbers of
 programmers who could write code in Python, the language most suited for
 the job. Eventually, it paid thrice the billing rate to a group of
 freelance Python programmers in the US. And learned a valuable lesson about
 the importance of a language named after the British television comedy
 series Monty Python.


 I'd like to know which company this `one of India's top software
 companies` is. Sounds like they don't network enough to find out the Python
 developers in India.


 For a nation regarded as a software programming powerhouse, the episode
 has salutary lessons. While skills in traditional computer languages meant
 for stitching software applications and maintaining large mainframe
 computers are a strength, ignoring Python could prove to be a costly
 mistake.

 Because companies like Infosyshttp://economictimes.
 indiatimes.com/infosys-technologies-ltd/stocks/companyid-10960.cms and
 TCS prefer proprietary languages like Java or dot NET most students think
 of these as an option in college. That is the reason you don't get good
 quality talent in the industry to work with us in Python, said Jofin
 Joseph, cofounder and chief operating officer of Profoundis, a Kochi-based
 technology startup which has been struggling for about a year to hire young
 Python programmers.


 Checked out the social network profiles of Profoundis, they are almost
 non-existent. They don't attend any events at all. I wonder how they are
 trying to hire Python programmers. That might tell us why they are
 struggling.


 Anyway, other points about big companies working with Java and as a result
 colleges teaching only those, is true. It's become a circle.

Re: [BangPypers] How to Distribute Commercial Python Applications

I haven't personally written any code that obfuscates the main source code,
but I think - you can search in those lines. An example of the same is the

check out their code/repository for any information on the way the code is
being obfuscated.
