Portland Python Meetup, Wed, Jun 25, 2014 Rob Bednark, rbednark at gmail.com @rbednark Shortlink to this Google Doc: http://bit.ly/pdxqa Add to the document real-time Got a problem? Want advice? Want to poll the audience? Got something to share? previous Q&A sessions below Python-related, but tangential questions are ok time signal Wed Jun 25, 2014 - 50 attendees Q: What video processing libraries are available for Python? (all kinds; discover what?s available) A: OpenCV (computer vision) MoviePy (made supercut automatically by parsing subtitle files) -- videogrep; cool animated gifs of ?Frozen? Q: Packaging? Distribution? dependendencies to external libraries A: cookiecutter (how to build package; write templates) distutils (super easy to create rpm?s) (someone has some notes on how-to: Here is the link to the lighning talk from Jan 2014: http://bit.ly/lightning-talk-on-pip-packages) setuptools Twitter - ?pants? - build single binary that contains Python, libraries; run anywhere; creates a ?pex? package; pythonwheels.com -- can do extensions; binary; install with pip Q: Favorite libraries, packages, frameworks? A: autopep8 spyne (soap web services) twisted (web framework) rq (Redis job queue) suds (client for SOAP web services) doctests (autotesting docstrings) Q: celery vs rq vs ?? A: good writeup read recently; rabbitmq with pika (celery is under the hood by default) celery is very abstract; hard to troubleshoot 0mq / zeromq Q: Who do you use / like for hosting? A: Digital Ocean (cheap; $5/mo 20gb ssd Linode (reliable; cut prices to match Digital Ocean; Opus Interactive (local - Portland; colocating metal) docker containers - AWS; Google Compute; easy to put app on multiple hosts; build and test container locally and then ship it to any server; like a supercharged chroot; limit memory; setup networking; Digital Ocean supports; boot2docker to run on a Mac; vagrant now supports docker; OpenStack supports; BeanStalk on AWS; Heroku (expensive, but carefree; 720 free dyno hours per month; PaaS) OpenShift - PaaS; RedHat offering; low bandwidth free option for low-traffic websites; Django 1.4 WebFaction - small company; portion of web server; do whatever you want; great support (reply within 30 mins); 260 euros / 2 yrs; 15 euros / month; CloudAtCost - pay once and get virtual server; $35; $1 / month Wed, May 28, 2014 - 36 attendees Q: resources/tools for migrating Django versions A: read the change logs; advice: do one version at a time (unit tests help) pyodbc has not kept up; don?t upgrade Django above 1.5 if you are using it; 1.5 => 1.6 was easy; depends on size of codebase -- did jump from 1.4 to 1.6 without any problems; Sublime is great for refactoring Q: tips/tricks/tools for troubleshooting excessive locking in Postgres when running massively multi-threaded Django apps A: could use lockless algorithms? ___ the locks in the same order; Way for Django to explicitly print out locking? logging module in Python? locks show up in Postgres locks table; Django ORM is creating the locks; Postgres 9.3.x Q: What are some topics you would like to see presented at a Portland Python meetup? A: automation, web-scraping, data mining; AI (machine-learning) Cython tips/hints desktop CNC (generating CNC files using gcode) (anything to do with artistic portion; dev env to take art and represent it in 3d ; sculpting using 3d printer; surface etching; consider using blender? take color image and translate to greyscale, then 3d Maya; do a file-to-file format conversion? something more robust; translate vector graphics Blender has some add-on modules (but limitations for cutting into metal) game development with Python general game playing with Python (AI) (e.g., playing Go and beating a human) pythonista -- iOS Python app Kivy -- cross-platform mobile dev platform using Python (build native iOS and Android apps) Django 1.7 is coming out soon and that could provide another talk topic maybe something like Django REST Framework backends with frontends on smartphones using Javascript frameworks like Cordova or angular.js. I was going to suggest that the Daniel Greenfield / Audrey Roy "Two Scoops of Django" book (2nd ed.) has some notes on moving to 1.6 but now that I'm home I see that it doesn't. Could be a related topic (for a Presentation Night talk, that is) to take major chunks of that book (maybe a bunch of chapters), summarize the "best practices" recommendations per chapter, and then do the equivalent of your reverse Q&A to update it to current best practices. Q: Anyone know ipython Notebook? Wanna know more? A: yes; (doing talk at OSCON, will consider doing one for Portland Python) Q:What are your favorite Python libraries, packages, and frameworks? A: BeautifulSoup Pandas Django configobj (alternative to configparser) fuzzywuzzy (matches words fuzzily) NLTK - natural lang toolkit argparse optparse docopt pyparse swig - David Beazley?s Simplified Wrapper and Interface Generator Flask mmstats - nice for metrics (memory-mapped stats) pdb Q: Has anyone done any OpenGL Python? libraries? A: Jason: PyOpenGL, but PyQt is better PyGame Pyglet Q: discussion around unit testing in Ruby world; any impact on testing in Python; How to do it well and right? A: TDD good way to do most things doctests mocking coverage frameworks with mocking; nosetest pymox (Google project for mocking) flexmock write app to capture gameplay with millisecond accuracy and run it back through the system over and over; write API commands into log files docker to test fabric scripts (integration test) (containers launch in milliseconds) (MySQL db preloaded in container) Q: How many of you are currently employed and using Python most every day in your job? A: about 11 of 36 Prepared questions that were never asked: Q: What do you like about Python3? Q: What kind of library / package / framework do you wish existed in Python? Q: I?ve heard Python packaging is a pain. Advice? Easier ways to do it? Q: What do you like about Python? Q: What do you not like about Python?
