OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.

Producer consumer pattern

Question: Can you write code implementing the consumer and producer pattern?

This is a classic concurrency problem where we have threads generating data to be consumed (producers) by other threads (consumers).

The implementation with POSIX threads can be a pain in the ass but it is quite straight forward in golang thanks to its concurrency constructs.

"""
TL/DR:
Never instantiate mock.Mock() directly.
Instead use either mock.create_autospec(YourClass) OR mock.patch('YourClass', autospec=True).

The "spec" feature of Mock is great, it helps avoid your mocked API drifting out of sync with your real API.
But there is a gotcha if you are mocking classes directly - it's easy to mock the class but you need to
ensure the spec applies to the *instance* as well.
