Starting over with git

I had some kind of screw up with my branching when trying to push to my github repository.  I never really figured out the exact issue, but since the repository had really minimal history i just removed it.  Here is what I did for the local repository;

From the terminal while in the correct directory i typed: rm -rf .git
Then I reinitialized the local repository with: git init

In github I removed the repository by going under settings when in the said repository and choosing remove.  I then created a new github repository and went back to the terminal to push files and all seems well.  It was an hour or two of cursing before i figured out what to do.

inject method

I came across this method when doing a google search for how to sum in an array.  I'm using it now to try and build my blackjack game.  It seems to be working fine for what I want it to do for now.  I'm not too sure yet on what all this method can do or problems that can arise.   I took the info from a stack overflow post,
http://stackoverflow.com/questions/1538789/how-to-sum-array-members-in-ruby.

My blackjack game is a work in progress.  I tried building this mostly on my own before looking at the tealeaf videos that show building the program up.  I don't know if i'll get a chance to totally finish my own version of it.  Here is where i'm at to show how i'm using inject.  Note that this will run for most instances, but i haven't fixed a couple issues yet.  Note inject returns a fixnum.



deck = [1,2,3,4,5,6,7,8,9,10,10,10,10,'Ace']

deck.shuffle!

ph = []
dh =[]

2.times do
  ph << deck.pop
  dh << deck.pop
  
end

puts 'Hand'
puts ph
puts

if ph.include? 'Ace'
puts 'Ace in hand'
end
puts
if ph.include? 'Ace'
puts 'Choose ace high or low' i'm expecting a 1 or 11 response here
ace = gets.chomp
ace = ace.to_i
ph.map! {|x| x == 'Ace' ? ace : x}
puts
puts ph
end


puts 'Hand total'
sum = ph.inject(:+) here i use inject to get the total for the players hand
puts sum

puts 'Would you like a hit or stay?'
reply = gets.chomp

puts
if reply == 'hit'
ph << deck.pop
puts ph
puts
puts 'Hand total'
sum = ph.inject(:+) new total for player after hit
puts sum
end

if reply == 'stay' and dh.inject(:+)<17
dh << deck.pop
puts 'Dealer hand'
puts dh
puts
puts 'Dealer total'
sum = dh.inject(:+) dealer total. need to fix for aces
puts sum
end
puts
if ph.inject(:+) > dh.inject(:+) comparing hands
puts 'You win!'
elsif dh.inject(:+) >=22
puts 'You win'
else
puts 'Dealer wins :('
end

Git it!

A reminder for me about pushing to github.  I'm sure this will become something i'll have memorized shortly, but i've already looked this up a couple times in the video from the precourse materials.  Now that it's posted here it will be much easier to get to.

Create a new repository on the command line

touch README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin git@github.com:jheaden/tealeaf.git
git push -u origin master

Push an existing repository from the command line

git remote add origin git@github.com:jheaden/tealeaf.git
git push -u origin master

Initial commit

Hello world.  I'm officially in week one of my Ruby on Rails online bootcamp!  This is an exciting, and a wee bit stressful, time.  I'm embarking and path to change careers from teaching mathematics to becoming a ruby/rails web developer.
  This blog is set up to document my progress over the next 4 months through the Tealeaf bootcamp.  I hope this turns out to be a useful way to keep notes on what i'm learning as I go.  My intention is to do some brief summaries of topics each week and what i've learned or am struggling with.  While this bootcamp will take a lot of time i hope to keep myself fit and active.  So i'll also post my weekly workouts, mostly running, as I go.  My weeks start on Monday.

Mon Sep 30  AM Easy run with Zola (2.5 miles).  PM Easy track.  4 400's between 6:15 and 5:45 effort (3 miles)

Tues Oct 1  PM CC practice.  Ran with kids (4 miles)

Wed Oct 2  AM Shevlin run with Zola (5.5 miles)

Thurs Oct 3  AM 45 min lap swim.  Running around cheering kids on at meet.  My first meet as cross country coach!  Tons of fun, very proud of my runners.

Fri Oct 4  AM Shevlin run with Zo (4 miles)


Well i doubt anyone will find and read this blog, but hey if you do comments are great!

Cheers
