GitHub - rcmorehead/scicoder2014: My repo for the scicoder 2014 stuff

#Scicoder 2014

This is my repo for Scicoder 2014.

Some Observations:

##Day 1

I maybe I should learn vi
macfusion (FUSE) is kinda cool
You can totally put equations in markdown (may not show on all systems) $$f(\omega) = sin(\omega - 1)^{w + 1}$$ (like github)
No coffee no snacks = unhappy!
Use git! It has a learning curve, but it will make you life better.

Operator Overloading, that seems fun and maybe dangerous.....
Stop doing from foo import *
Singleton - make one unique object that is always the same object no matter how many times you call it. Very handy.......
Oh yeah, I always forget that sets are a thing

##Day 2

Objects are fun!
Numpy!
Neat trick, you can make numpy arrays immutable
- array.flags.writeable = False
Use numpy functions only on numpy arrays
@property decorator can make methods into properties
Use 'Lazy Loading' Only load data when you need it, not before.
test you code, checkout pytest
If you find a bug, add a test for that bug to your test script and then you will spot it if it comes back

Astropy
No coffee at all today
Travis CI - Oh that is super cool. It auto runs tests for each build of your code.
Astropy is very eager for contributions

##Day 3

Oh sure, the morning I buy coffee they get coffee.
Document your code
Databases!
Databases = linking tables with unique items
SQLlite for small things, postgresql for bigger things - multiple users
Oracle is crazy expansive
You might want to create a database when you get > few thousand entries or when you need to match/cross-correlate among many datasets
sqlalchemy is your friend
Oooh, custom behavior in the model classes specification
Use sessions, you want everything to work or fail. In database there is no undo

matplotlib (no matplotlib)
errr no wait, regular expressions instead [pdf](9 - Introduction to Regular Expressions.pdf )
Scipy exists
Logging way more handy then print statements!
argparse is more advances command line argumments
hmmm, found good color scheme
