Brian #1: Why Senior Devs Write Dumb Code

• “Any fool can write code that a computer can understand. Good programmers write code that humans can understand.” - Kent Beck
• Code that is clean, straightforward, obvious, and easy to read actually takes practice to achieve.
• Follow principles like YAGNI, Singe Responsibility, DRY, etc.
• Avoid clever one-liners, weird abstractions.
• Esoteric language features.
• Code needs to be readable and easily understood while under time and stress pressure.

Michael #2: GeoAlchemy 2

• GeoAlchemy 2 provides extensions to SQLAlchemy for working with spatial databases.
• GeoAlchemy 2 focuses on PostGIS. Aims to be simpler than its predecessor, GeoAlchemy.
• Using it:
  • Connect (e.g. Postgres)
  • Declare a Mapping

    class Lake(Base):
         __tablename__ = 'lake'
         id = Column(Integer, primary_key=True)
         name = Column(String)
         geom = Column(Geometry('POLYGON'))

• Create a table (via the engine)
• Create an Instance of the Mapped Class
• Inserts like standard SQLAlchmey
• Spatial Query

    from sqlalchemy import func
    query = session.query(Lake).filter(
             func.ST_Contains(Lake.geom, 'POINT(4 1)'))

    query = session.query(Lake.name,
          Lake.geom.ST_Buffer(2).ST_Area().label('bufferarea'))

Brian #3: QtPyConvert

• An automatic Python Qt binding transpiler to the Qt.py abstraction layer.
• QtPyConvert supports the following bindings out of the box:
  • PyQt4
  • PySide
  • PyQt5
  • PySide2
• Conversions leave code comments in place, with the help of RedBaron
• Converts to Qt.py
  • Minimal Python 2 & 3 shim around all Qt bindings - PySide, PySide2, PyQt4 and PyQt5

Michael #4: You Don't Have To Be a Workaholic To Win: 13 Alternative Ways To Stand Out

• Max Q analogy
• The tips
• Creativity
• Stubbornness
• Curiosity
• Kindness
• Planning
• Improvisation
• Enthusiasm
• Communication
• Presence
• Collaboration
• Willingness
• Patience
• Institutional Knowledge

Brian #5: RedBaron

• RedBaron is a python library to make the process of writing code that modify source code as easy and as simple as possible.
  • writing custom refactoring, generic refactoring, tools,
• Used by QtPyConvert to achieve the conversion while leaving code comments in place
• Uses the full syntax tree, FST. Like an AST, but keeps all information, including comments and formatting.
• possible uses:
  • rename a variable in a source file... without clashing with things that are not a variable (example: stuff inside a string)
  • inline a function/method
  • extract a function/method from a series of line of code
  • split a class into several classes
  • split a file into several modules
  • convert your whole code base from one ORM to another
  • do custom refactoring operation not implemented by IDE

Michael #6: Project Beeware AppStore

• Project BeeWare has just released its first iPhone app made in Python using its Briefcase tool.
• Simple travel app for currency and tip calculations
• Briefcase: A distutils extension to assist in packaging Python projects as standalone applications. Briefcase is a tool for converting a Python project into a standalone native application. You can package projects for:
  • Mac
  • Windows
  • Linux
  • iPhone/iPad
  • Android
  • AppleTV
  • tvOS
• While there are other Python GUI toolkits aiming to enable Python developers to build and deploy iOS apps, like for instance the very nice Pythonista app, the BeeWare project is a bit different because it aims at cross-platform compatibility and native widgets with a set of different tools, like Briefcase and Toga.
