	## Where to being with this one? I got to the words = [] portion but wasn't
	## sure how to get multiple words, entered separately a.) into the array and b.) on a loop.
	## After trying a variety of ways, I broke down and did some googling.

ejallday / self implicitly?

Last active December 15, 2015 13:48

I'm new at this, but it's my understanding that with classes: the 'name of the class' (Name), 'self' and simply typing 'new' garner the same result. Name and 'self' are receivers and they invoke #new. In the absence of a receiver and simply typing 'new', the method calls whatever the current object is, which happens to be 'self' and or Name. Why…

	class Array

	def pad!(min_size, value = nil)
	if self.length < min_size
	self.fill(value, self.length...min_size)
	else
	return self
	end
	end

ejallday / Scamming the system!!

UPDATED: After realizing that very large Fibonacci numbers would not work with my formula, I went about it a bit differently. This time I created a while loop tied to the input being smaller than the last element in my fib array, creating a Fibonacci sequence where fib[-1] should == i if i is in fact fibonacci. This seemed like a more roundabout…

	def is_fibonacci?(i)
	fib = [0,1]
	while i > fib[-1]
	fib << (fib[-1] + fib[-2])
	end
	fib.include?(i)
	end

ejallday / RPN_Steps

Created April 3, 2013 02:24

This is my version of the RPN Calculator after lots of googling. This is the full annotated version with my final at the bottom. I'm going to go through my entire thought process and things I struggled with. I was only able to come up with my final solution after seeing someone else's that was similar... But I learned a new trick in the process:…

	# Before I started this exercise I read the wikipedia on reverse Polish notation. It made
	# sense to me for the most part, but then I discovered their chart about stacks which is a
	# total GEM! However, last night I read ericatdbc.tumblr.com 's blog about the importance of
	# understanding the stack data structure by the end of week one. So I did some additional
	# research but still didn't fully understand how it worked. At this point, I thought I
	# should give it a try anyways.

	# Step 1: After reading the wiki and the blog I knew I needed to get my input string into
	# an array. Using one of the example strings on Socrates I defined the string as a variable and
	# using the class String #split method I was able to achieve that. You will also see that

How to prep for Dev Bootcamp... According to 2 Dev Bootcamp Graduates.

	### Advice from Graduate # 1: ###

	"You're going to want to save this email chain and refer to it during DBC:

	.... You should get this book (Well Grounded Rubyist) and go through the entire thing,
	making sure to do the coding exercises along with the book. Once you finish, do it again.
	Then, if you have time, do it one more time. This is the best book on Ruby, IMHO. If you
	do just this paragraph before rolling into DBC, you will dominate.

	If at any point in time you feel like the book isn't doing a good job of explaining things,

Building an Mp3 Playlist.

	# The hardest part about this exercise for me was figuring out how to get the filenames
	# from my music folder into an array that could be fed into this method. I had never used
	# the Dir[] class before so it was a bit foreign to me to think that I could just give Dir
	# a file path and a parameter to collect file extensions and they would all just be in an
	# array. Good to know.

	def shuffle array
	array = array.shuffle!

	filename = 'Erics_playlist.m3u'
