What makes you think JS or PHP are "more simple" for that audience? There are plenty of Ruby jobs out there, and it's an elegant and well-designed language that's got a mature framework. Especially crucial for relative beginners: it doesn't have the flavor-of-the-week problem that JS does, nor is its most prominent example a legacy mess, as Wordpress is for PHP.

all most all of the web is written in PHP, a beginner can't understand how everything fits together by learning Ruby. With php you can literally insert it into HTML. For me is all about the big picture, Plus I think there are more jobs in PHP than Ruby

I see you make heavy use of Cloud9, glad to see that I'm not the only one using it as a learning sandbox environment. It is truly a great platform, I use it to introduce people to Linux (terminal, editing files, etc.) without the hassle of setting a virtualbox, installing any software in their computers, or risking my machines.

I tried it few weeks back and sadly they force you to add credit card to proceed. Few seconds of googling showed people using fake ones to circumvent it. Not really interested in that nor exposing card details.

Do you have a website for your course? I'd love to check it out.

Can you give an example of solving a problem using code vs coding?

Parse this file and tell me the total of all $ amounts, and the line where we've reached 50% of the total $. How do you approach this problem and break it down. I've seen problems like this solved by looping through the file twice, because they answer one question at a time... But I'm hoping there is something out there that can teach the general process of breaking down the problem, identifying loops, identifying ge…

  # assuming file with $100\n$200\n$23\n$50 etc.
  linenum_vals = []
  with open('numbers.txt') as input_file:
      for i, line in enumerate(input_file):
         try:
             linenum_vals.append([i, float(line[:-1][1:])])
         except ValueError:
             print("Not a number value on line", i)
  
  total = 0
  for i in linenum_vals:
      total += i[1]
  
  half = total/2.0
  
  for p in range(len(linenum_vals)):
      if linenum_vals[p][1] == half:
          print("Half of total found on line", linenum_vals[p][0])
          break
      else:
          if linenum_vals[p-1][1]  half:
              print("Half of total in between lines", p-1, p)
              break
          else:
              if p+1 != len(linenum_vals):
                  if linenum_vals[p][1]  half:
                      print("Half of total in between lines", p, p+1)
                      break
          print("Half of total wasn't found in the file.") # probably because the list of values isn't in order
