Last active August 29, 2015 13:55 — forked from spara/fur_elise.ino
Added RGB color coordination on pins 2,3, and 4, respectively. The lights glow at different intervals, creating combinations of all primary colors to enhance the music experience.
int r = 2;
int g = 3;
int b = 4;
void setup() {
pinMode(10, OUTPUT);
pinMode(r, OUTPUT);
pinMode(g, OUTPUT);
pinMode(b, OUTPUT);

mosdragon / har_script.rb
Created March 23, 2014 02:30
Script to open HAR file passed as argument and display the fastest and slowest resources along with their respective loading times. Currently optimized to follow Object Oriented design principles.
# This version of har_script.rb adheres more strictly to
# OOP principles because it enables code reusability without code duplication
require 'json'
require 'open-uri'
# Helper Method nested_search goes through nested Hashes, finds message in
# desired key.
# @param obj, the hash
# @param key, the desired key to be found, nested within obj
# @globalVar, the global variable to be modified

A utility for taking discrete valued attributes and replacing with numerical values
import numpy as np
import pandas as pd
def clean_data(df, fill_method='ffill'):
'''
Takes in a pandas DataFrame and changes all string attributes and outputs
to integers. Returns the DataFrame and the mapping
fill_method can be:
- 'ffill': forward fill
- 'bfill': backward fill
