# Mac OS X Lion introduced a new, iOS-like context menu when you press and hold a key
# that enables you to choose a character from a menu of options. If you are on Lion
# try it by pressing and holding down 'e' in any app that uses the default NSTextField
# for input.
#
# It's a nice feature and continues the blending of Mac OS X and iOS features. However,
# it's a nightmare to deal with in Sublime Text if you're running Vintage (Vim) mode,
# as it means you cannot press and hold h/j/k/l to move through your file. You have
# to repeatedly press the keys to navigate.

###Querying the database

Now you just need to learn a little bit of new sqls for selecting stuff (creating and updating is transparent). Find records that contains a key named 'foo’:

Person.where("data ? 'foo'")

Coding Practice Resources
Simple List of Websites
  • Project Euler - The #1 goto site for coding practice on the internet, IMO.
  • Rosetta Code - Unlike most other sites on this list, Rosetta Code is not a contest site. There are problems listed, and so are the solutions, in a plethora of different languages. You can go check out the problems, solve them, check out other solutions. It's goal is to solve problems in as many languages as possible.
  • Code Chef - Holds monthly programming contests
  • UVa Online Judge - Contains hundreds of problems, which can be downloaded too
  • Coderbyte
    • Another coding competition site
  • The Python Challenge - A pretty cool & very difficult challenge. Makes you think, a lot, and not just for coding.
  • Code Golf Stack Exchange - A programming challenge with a twist - The code has to be the smallest.
  • Anarchy Golf - Another place to golf
