Brian #1: Correcting Documentation for a Deployed Python Package

• "A clever way to release new documentation without releasing a new package that might confuse your user base.”
• Upload changes to pypi without bumping the version by using post release version numbers: 0.3.2 => 0.3.2.post1
• Prevent documentation issues by using restview --long-description before uploading. (or use md and really any md converter)

Also:

• Packaging Python Projects : revamped pypa tutorial that works pretty darned well.
• Using TestPyPI : more detailed instructions on testing with TestPyPI before pushing to final spot.

Nina #2: Flask Mega Tutorial

• Amazing resource for developers who’d like to learn about building web applications with Flask in Python.
• Covers important topics like databases, internationalization, and dates and times.
• Three full sections on deploying your web app using Linux, Heroku, or containers.
• VS Code IDE has great Flask support.
• Try Azure with a $200 credit to deploy Flask apps.

Michael #3: 10 common security gotchas in Python and how to avoid them

• Article by Anthony Shaw (congrats on being a 2018 PSF Fellow)
• The 10 topics
  • Input injection (see little bobby tables)
  • Use an ORM (db) or shlex module to escape input correctly (process)
  • Parsing XML
  • Assert statements
  • Timing attacks
  • A polluted site-packages or import path
  • Temporary files
  • Using yaml.load
  • Pickles
  • Using the system Python runtime and not patching it
  • Not patching your dependencies

Brian #4: pre-commit “A framework for managing and maintaining multi-language pre-commit hooks.”

• Describe pre-commit actions using yaml.
• Lots of projects already use it, like black.
• Does the work for you so you don’t have to read up on git commit hooks and such.
• Test out hooks ahead of time with pre-commit run [HTML_REMOVED]

Nina #5: Python 3.7 release and PSF board members

• Python 3.7 has just been released today! 🎉
• New Features Overview Blog Post

• 4 New PSF Board members elected - Congratulations to them!
  • Anna Ossowski
  • Christopher Neugebauer
  • Jeff Triplett
  • Katie McLaughlin

Michael #6: Vibora web framework

• A new speedy web framework
• Only 14 days old, but has 21 contributors and 2k stars
• Just like Flask: Vibora APIs were heavily inspired by the awesome Flask.
• Schemas validation, template engine, sessions and many more features were written from scratch to provide great performance along with an elegant async interface.
• Vibora also take advantage of multiple CPU cores by default thanks to the multi-processed architecture. Uvloop and other C speed-ups are used when available.
• Virtual Hosts: Maybe you have different domains and you want to host them all with a single Vibora application.
• Deployment has its own HTTP app server
• Docs need help
