Consider the problem of predicting how well a student does in her second year of college/university, given how well she did in her first year.
Specifically, let x be equal to the number of "A" grades (including A-. A and A+ grades) that a student receives in their first year of college (freshmen year). We would like to predict the value of y, which we define as the number of "A" grades they get in their second year (sophomore year).

# Functions ============================================== | |
# return 1 if global command line program installed, else 0 | |
# example | |
# echo "node: $(program_is_installed node)" | |
function program_is_installed { | |
# set to 1 initially | |
local return_=1 |
The trick? pass the file descriptor from a parent process and have the server.listen reuse that descriptor. So multiprocess in their own memory space (but with ENV shared usually)
It does not balance, it leaves it to the kernel.
In the last nodejs > 0.8 there is a cluster module (functional although marked experimental)

- Simple cluster example:
This is a quick guide to OAuth2 support in GitHub for developers. This is still experimental and could change at any moment. This Gist will serve as a living document until it becomes finalized at Develop.GitHub.com.
OAuth2 is a protocol that lets external apps request authorization to private details in your GitHub account without getting your password. All developers need to register their application before getting started.
