THREAD - How about a bunch of blog posts on #Space and #Astronomy? Yes, I have more than you can imagine - especially since these are really just #physics topics. Hold on - because this is going to be a bit large.
2/ Here is an answer to my fav astronomy question EVER - "What would the phases of the moon look like if the moon was a cube?" wired.com/2015/09/moon-c…
3/ The great thing about the cube moon question is that it really tests if students understand phases of the moon rather than just recalling factual stuff. Here is my python model of a cube and spherical moon
If you're new to #python programming, welcome aboard! I've spotted a few techniques that newcomers miss out on and thus learn more slowly.
First, and most important: install and use ipython. You will learn APIs much faster with tab completion and the ability to write foo? to see documentation for foo.
The default python interpreter will slow you down.

Second, install a linter in your editor. I suggest pyflakes for newcomers. This will catch lots of silly errors and give you fast feedback on syntax.
High level #python #tutorial thread:
Python is a high level language that runs bytecode in its virtual machine.
Everything is an object.
It supports OOP up to multiple inheritance and functional programming.
Typing is polymorphic - duck typing is preferred

A Python script is a file with a name like name.py - we indent at four spaces (it matters), comments (after #) don't execute - and is typically written like:
def main(): # function
print("Hello world")
if __name__ == '__main__': # then entry point
main()
def main(): # function
print("Hello world")
if __name__ == '__main__': # then entry point
main()
A module is a reusable script:
"""this is a docstring at the top of the module - gives help on the module"""
import this # do imports at the top
def main(): # main at top or bottom
"""functions get docstrings too"""
if __name__... always at the bottom, assumed from now on
"""this is a docstring at the top of the module - gives help on the module"""
import this # do imports at the top
def main(): # main at top or bottom

this, still the best book on writing a compiler. Though, not as clear and broad as i thought.
there are thievery pdf versions online, but all code/formula are screwed. You better buy the real thing.
