Clustering: The basics

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)

• http://nodejs.org/api/cluster.html
• Simple cluster example:

Understanding the Node event loop

There are two important things to remember about the Node event loop. The

magic003

• Consider using HashMap when comparing two strings or arrays.
• When handling string problems, ask if it is ASCII. Use an array of length 256 if it is.
• When comparing two strings or arrays, sort them first.
• Using StringBuffer for the temporary result for string concatenate.
• Prepend a dummy node for linked list problems.
• Remember integer might be negative!
• Computer cannot accurately represent float/double, use epsilon for equality check.

Common tricks:

• Interval intersection: 1) sort by start point, binary search the end point 2) sort both start and end points, go through the array, for start point i++, for end point i--.
