Agree too many screen repositioned. And click next you could use the right arrow key.

I found Udacity's class (CS373, ST101) and the 2011 ai class also explained bayesian very well by Sebastian Thrun.

I have question on level 21, it said:

Contribute to this repository by making a pull request on Github.

The Hint: Forking the repository would be a good start!

Could someone clarify a bit more?

The goal for the contribute level is for you to contribute something valuable to githug, such as a level or a bug fix.

I am wondering how many levels are there? o.O ?

Hi there, I think password is working perfect. And we just need to figure out a way to remember all passwords into our brain in a unforgettable way. Here is what I do: Password for xxx: First GF's birthday(yymmdd)+favorite city(2 letters, first letter CAP)+ high school student no.+last 3 letters of my all time favorite movie this would result: 760925Lu201228can And you can store the statement in your gmail. Only you will know the answer. Then you don't forget! Also I have 3 level passwords. High Medium Whatever High: I will think of a password as I demonstrated above (at least 4 questions). Medium: I will think of a password for just 2 questions. Whatever: would be a stupid password but for accounts I don't care if it's hacked(stack overflow, github..etc) Among all tools, maybe it's better to write your password and put in your pillow. and forget all the technical stuff.

I think the bad programmer won't see this post as they don't check Hacker News on a daily basis... :P
