Michael #2: Java goes paid

  • Oracle's new Java SE subs: Code and support for $25/processor/month
  • Prepare for audit after inevitable change, says Oracle licensing consultant
  • There’s also a little bit of stick to go with the carrot, because come January 2019 Java SE 8 on the desktop won’t be updated any more … unless you buy a sub.
  • The short version is that every commercial enterprise needs to look at their Java SE (Standard Edition) usage to see if they need to do something with licensing.

Brian #3: Absolute vs Relative Imports in Python

  • Review of how imports are used, along with subpackages and from
    • ex: from package.sub import func
  • Relative: what does this mean:
    from .some_module import some_class
    from ..some_package import some_function
    from . import some_class

Michael #4: pyxel - A retro game engine for Python

  • Thanks to its simple specifications inspired by retro gaming consoles, such as only 16 colors can be displayed and only 4 sounds can be played back at the same time, you can feel free to enjoy making pixel art style games.
  • Run on Windows, Mac, and Linux
  • Code writing with Python3
  • After installing Pyxel, the examples of Pyxel will be copied to the current directory with the following command: install_pyxel_examples

Brian #5: Click 7.0 Released

  • Changelog
  • Drop support for Python 2.6 and 3.3.
  • Add native ZSH autocompletion support.
  • Usage errors now hint at the --help option
  • Really long list of changes since the last release at the beginning of 2017

Michael #6: How we spent 30k USD in Firebase in less than 72 hours

  • the largest crowdfunding campaign in Colombia, collecting 3 times more than the previous record so far in only two days!
  • Run on the Vaki platform -- subject of this article
  • We had reached more than 2 million sessions, more than 20 million pages visited and received more than 15 thousand supports. This averages to a thousand users active on the site in average and collecting more than 20 supports per minute.
  • Site was running slow, tried things like upgraded the frontend frameworks
  • Logged into Firebase: had spent $30,356.56 USD in just 72 hours! Going at $600/hr
  • All came down to a very bad implementation of this.loadPayments().
  • Comments are interesting
  • It could happen to any of us, it happened to me this month.
