In the tradition of previous AfricaDataScience workshops, a summer school on machine learning and data science will be held prior to the main workshop.




The last few years have witnessed an explosion in the quantity and variety of data available in Africa, produced either as a by-product of digital services, from sensors or measuring devices, satellites and from many other sources.

Data science seeks to exploit advances in machine learning and statistics to make sense of the growing amounts of data available from various sources.


Summer School on Machine Learning and Data Science
Dates: June 27th - 29th 2016
Venue: College of Computing and Information Science - Makerere University


In the tradition of previous AfricaDataScience workshops, a summer school on machine learning and data science will be held prior to the main workshop. This summer school will target graduate students, researchers and professionals working with huge amounts of data or unique datasets.  To benefit from this course participants are encouraged to have some background in programming particularly programming with Python.


Thank you ChiPy team for all you do!

The site is running on PHP for Wordpress.  The person who comes on can implement in that, or migrate to the main site (which is Python powered).  It is really up to you.

The are getting a new data file next week, and want to get going ASAP!

This is really a part time web, data science, visualization gig -- and has to potential to be long term.

If interested, contact me off list (jdumblauskas at gmail.com<mailto:jdumblauskas at gmail.com>) and I can get your resume over.

The people who sent in resumes for the first role, if still interested, can also put their hat in for this role as well (just let me know).

Since this is a non profit -- we are not taking a referral fee (like last time), but just trying to get a good python dev in doing some great work.

Hi ChiPy:

I'm looking for a developer (or two) to be mentored by me for about 20hrs a
week starting ASAP - July.  We will meet 2x a week for 1hr and once in
person every two weeks--in Chicago.  There will be some pay (small)
involved and ChiPy will be compensated a referral, so the whole group
benefits.

This is for someone who is looking to get involved with a high-performing
team that is pushing the boundaries of technology and may be interested in
joining full time after completion.

Ideally, I am looking for someone who has experience with Django Rest
Framework / numpy / pandas and has exposure to financial statements /
accounting.  Exposure to Vue.js/Sass and DevOps (Vagrant, Ansible, AWS,
etc.) would be a bonus.

If you are already in the mentorship program, please clear your involvement
with Tee and/or your mentor/mentee(s) so there are no conflicts.

Please send me your name and brief description of your qualifications to
brianhray at gmail.com.

I like that this is an internship this year.  I did the student developer version last year and gained a lot of insight into the development process but I couldn't contribute much as a developer.  I'd like to warn that at the time, in my case, I had a severe lack of experience with Django and Python that made me a poor fit overall.  This is really a great experience for someone with some programming experience but not much professional experience.  

Brian is an excellent teacher though, thanks for taking time to do this!

Hello Chipy,

There is a non profit that is looking for some development help.  They
don't have budget so this would be a volunteer opportunity.  This group is
trying to increase open government in Illinois (see
http://www.citizenparticipation.org/)

There are 2 phases to this

1) do some data scrubbing of an excel file
2) update the website that will implement the candidate search process (
http://candidateswanted.info/)

The stack is not python (yet) but maybe could be.

I am going to take a crack at #1 using 'Pandas" in honor of Jason Wirth :)
(I have some spare cycles).

as for item 2, if anyone has interest, or spare cycles, please message me
off list.  I plan on working with the Director of this non profit and see
if we can break down the tasks into chunks.  Of course, if the website is
going to stay ASP.net, this is probably not something we can assist with.

I'll keep everyone posted (and give an update at the next meeting for sure).

thx

Jerry

Message-ID: <CA866A0F-1C22-40EE-A8C4-9ECCC37C1F9B@gmail.com>

Hi all?

The July meeting of ChiPy?s Web Special Interest Group is scheduled for Thursday, July 28. We are looking for a speaker or two (or three!) to fill about 30?40min of time on ANY subject that involves using Python to build and/or serve web applications. Please contact myself or Adam Bain (off list is fine) if you want to give a talk. This might be a great time to practice a talk if you plan to speak at a regional PyCon like PyOhio or PyGotham, or if you?ve never given a talk and want to take a crack at it. Meetings are very casual and there are developers of all skill levels, so there?s little pressure and the subject matter and complexity are wide open.

- You don?t need to be an experienced speaker
- Your talk doesn?t have to be complicated
- A talk can be 5, 10, 20, 30 minutes, whatever you need
- You don?t have to be a Django/flask/falcon/tornado/Python expert to have something meaningful to say

Please let us know sooner rather than later so we can properly promote the meeting and the speaker topics.


Thanks,
Chris Foresman

This is a very open ended question, but what do people think about python
code like:

class Point(namedtuple("Point", "x y")):
    # additional methods here

Is it pythonic?

Does it buy anything besides keystrokes?

Do you use it in production?

Thanks,

Why namedtuple instead of __slots__? What are you getting from namedtuple?

If you do have a good reason to use namedtuple, I think it's OK to use it
like this -- it reads clearly to me, and is easy to refactor. However, I
would call the base class "PointBase" rather than "Point".

Basically, I was reading someone else code (chess engine called sunfish)
and saw this.

I went back to the python namedtuple docs and saw it as an example.  So I
know it is possible and possibly pythonic.

But, I have the same question as you Adam, why not use slots instead?

I am not seeing any advantages straight away.

It seems to me its the efficiency of creating the overhead object, and what
you are storing it in

I don't have personal benchmarks for this, but here are two resources that
helped me understand:

Hi ChiPy,

We are looking for speakers for the July 14th ChiPy meeting.  We are happy
to have speakers of all experience levels. Here's a great way to get
involved with the Python community.

In addition to our normal talks, we are looking for someone who is willing
to give a 5-10 minute "Module of the Month" lightning talk, covering a
useful Python module or module feature.

*If you'd like to speak, keep in mind:*

   - Talks typically range between 10 and 45 min (including question time)
   - Talks should be Python-related.

*To submit a talk:*

   - Please send your talk idea to this list.
   - We'll need you to fill out the talk proposal form to get you on the
   schedule.
      - http://www.chipy.org/meetings/topics/propose


Let me know if you have any questions, and hope to hear from you soon!

If you'd like to attend the next meeting, you can rsvp at chipy.org or via
our Meetup <http://www.meetup.com/_ChiPy_/> group.

Subject: [Chicago] Braintree Environment, Configuration, and Thread Safety
Message-ID: <CABs1gezLspgAY45wWwGnLbW9cQiep-23djVYhFwxroMpUpKbfA@mail.gmail.com>

Hey everyone,

Does anyone know if it is safe to put Braintree python client code into a
module from a thread safety perspective for a web app?  Or any other
caveats?

I'm not switching environments or anything mid request, just trying to
clean up some code.

I'm trying to refactor a web app which has some boilerplate code in the
models and controllers, and I wanted to move this into a module.

I wasn't sure if it does some internal session handling etc, which might
conflict if imported, but would not if run per request.

I've looked through the source on
https://github.com/braintree/braintree_python

which looks like most of the calls I make are static methods, but I was
looking for any gotchas.

Thanks!

-Mark

Yep, it's safe.

You even can switch environments / configs etc. by instantiating a
configuration object and gateway, and then using that instead of the static
methods. I know Ray (another ChiPy member who works at Braintree) has
example code for that, and I'll make sure he sends it out on Monday if he
doesn't see this thread by then -- even though it sounds like you don't
need it.

Message-ID: <CAHCs_rYtZHS5cHo=duxhCkBQKvC_Ak44hS11gO66UJFt3ZKt=A@mail.gmail.com>

Hi all,

I'm subscribed to the PyDataChi meetup and thought I'd mention an upcoming
event. It looks really neat.

http://www.meetup.com/PyDataChi/events/232701965/

"Build nights are relaxed evenings where we we work together on projects in
the open source data science ecosystem like Jupyter, NumPy, Julia, and
Pandas.

If you're new to open source, veterans will help you through the process of
identifying issues to work on and submitting a pull request. If you're
already comfortable working on open source projects, you can come with an
idea of something you'd like to work on and recruit others to help. If you
have no idea what you'd like to work on, that's fine too! You can pair with
someone else or we can suggest open issues based on your interests."

Mark,

I hope this helps. They're almost identical, but because you're accessing
an attribute on the gateway instance you just downcase the attribute:

##########################################
import braintree

#Global
braintree.Configuration.configure(
    braintree.Environment.Sandbox,
    "some_bad_public_id",
    "some_bad_public_key",
    "some_bad_private_key"
)

#Instance
working_gateway = braintree.BraintreeGateway(braintree.Configuration(
    braintree.Environment.Sandbox,
    "some_good_public_id",
    "some_good_public_key",
    "some_good_private_key"
))

sale_params = {
    "amount": "1000.00",
    "payment_method_nonce": "fake-valid-nonce",
    "options": {
        "submit_for_settlement": True
    }
}

result_1 = braintree.Transaction.sale(sale_params)
## Will fail, because the keys ar bad

result_2 = braintree.transaction.sale(sale_params)
## Will succeed, because the instance keys are good

result_3 = braintree.Transaction.sale(sale_params)
## Will fail, because the static keys are still bad!
##########################################

Sprout Social will be hosting the Web SIG (Special Interest Group) on
Tuesday, July 26. Doors open at 6 and talks begin at 6:30.

Sprout Social is located at 131 S Dearborn St., Ste. 1000.

Please RSVP before Monday with your first and last name on your ID for
security desk here: http://www.meetup.com/_ChiPy_/events/232572677/

As usual, we should have some pizza and beers, as well as some
non-alcoholic refreshments.

We have a great talk by Aijaz Ansari lined up, but we could accomodate an
additional short 5-10 min talk. It can be anything related using Python to
do anything Web-related; feel free to talk about your pet project, any cool
libraries you are using, technical challenges you recently overcame, etc.
We are also seeking speakers for the following August meetup, so if you
have an idea for a talk please drop us line.

Feel free to respond to this thread, or contact me (foresmac at gmail.com) or
Adam (adam.bain at vokal.io) directly.

I'm thinking about Blockchain in general, not just with Bitcoin. The
distributed element reminds me of distributed version control in some ways.

It seems like some other applications are being built on blockchains and I
was wondering what others in the group have seen.

Thanks Don. Yes, I already connected with Jason Rowley on this topic last
week and we had a lengthy conversation and continue
to correspond. Meanwhile, it would be nice to hear a couple
other perspectives.

I'd describe blockchain as three things: (a) some schema to store
records/events/contracts in, and a serialization method to make them
hashable, (b) a cryptographic method to combine the new record and previous
record's signature to produce a new signature, and (c) keeping signatures
public so other parties can make sure nobody can rewrite history.

As far as I know, and someone please correct me if I'm wrong on any of
this, the distributed system of Bitcoin, et al., is both a method to keep
things public, but also is needed by the schema that stores the records
(goes beyond the essence of blockchain). Also, I think that the actual
record doesn't need to be public. A secret record could be verified to have
been entered into the chain at some point by parties recomputing the next
signature.

No points for clarity :P

Now that I think about it, Git is kinda blockchain-y if you were to publish
the commit hashes/log. It's schema is all about files (blobs) and
directories (trees) making up a graph. With some searching apparently
they're both Merkle trees <https://en.wikipedia.org/wiki/Merkle_tree>.

You may have seen Quantopian recently acquired 250M of Steve Cohen's money
to invest. With a winning strategy you may be able to manage some of that
money.

Thanks to IIT Stuart School of Business and Quantopain for hosting a
hackathon.  We will take the day this Saturday to build strategies and get
going on the platform. Everyone is welcome, if you already have a strategy
going or if you are new to the idea of algorithmic investing please
consider coming. Let's hack wall street together.
