Ruby feels like Perl in that there's a TON of different ways to do one thing. Bloated API? Theme music: Ween - So many people in the neighborhood

mjhea0 / map_vs_collect.rb
Created April 23, 2013 15:51
map and collect do the exact same thing - why? why don't they deprecate one of them? why do i see map used more?
numbers = (1..10)
array1 = numbers.to_a
array2 = numbers.to_a
# map
strings_map = array1.map(&:to_s)
# collect
strings_collect = array2.collect(&:to_s)

Find the sum of the odd-valued terms of the Fibonacci sequence whose values do not exceed 2,000.
num1 = 0

i = num1 + num2
# if i is odd, add it to the total
if i % 2 != 0

Created May 1, 2013 18:11
Sentiment Analysis via R
Create an app on https://dev.twitter.com/, make sure you leave Callback URL blank (so that it will return to a page where twitter shows you a PIN, useful during twitCred$handshake below. Don't worry yet, read on.)
Run these on R (on separate lines):
reqURL <- "https://api.twitter.com/oauth/request_token"
accessURL <- "http://api.twitter.com/oauth/access_token"
authURL <- "http://api.twitter.com/oauth/authorize"
consumerKey <- "yourconsumerkey"
consumerSecret <- "yourconsumersecret"
twitCred <- OAuthFactory$new(consumerKey=consumerKey,consumerSecret=consumerSecret,requestURL=reqURL,accessURL=accessURL,authURL=authURL)
