PyOh March 2018


Great turnout, 77 people rsvp,d at least 40 came. Out of one case of pizza,
one slice was left


Two of the new people :


Eric - Quant from Boston

Trey - IoT, Python


PyOhio is July 29-30 2018  @ the OHio Union. Looking for speakers and
sponsors.


PyCon is in Cleveland in May - is not free like PyOhio


Guy Royce will speak about machine learning in April meeting 4-30-2018


Harry Linder spoke about how to create your own custom search engine


We actually experimented with recording, looking for a spare camera for
video recording


This is up on GitHub - but where ?


Lean into your edge - make connections


Why build your own search engine ? Results are often inaccurate, incomplete
also, there is a serious search bubble effect (unless you use Duck Duck Go)


Surveys only get a small response, so each respondent has an outsized
influence


Start with accurate information


Python - of course !

Flask - web framework

Whoosh - search

Scrappy + Portia - web scrapers


Frames are very difficult- especially if they load things that do not
refresh the page.


Also used :


Virtualenv - package management

GitHub - store and share your code. And use for deployment

Heroku - better than AWS for this purpose

Cloud 9 -  bought by AWS.

Google errors-  See project notes - Harry found AWS to be error prone

Stackoverflow -

Panic - not really


Result : https://stormy-lowlands-80953.herokuapp.com


Shout out to Lynda.com for the Flask tutorial


! Consider storing the code with the web site that you scrape


Whoosh can index things without a dB

. Beautiful Soup


Travis spoke about pipenv - very good for package and dependency management
