Ruby Tips - How to figure out where a method is defined

The other day when I was dabbling with the huge codebase, I was wondering where a particular method was being declared for a specific method. I wanted to know this because my greps didn't turn out to volatile and didn't return any results



The Solution

The Ruby interpreter has certain methods that can be used for identifying under which module or class, the particular method is being defined. See the example below.


So using the .source_location you will be able to figure which file it has been declared.

You are in a cold conference room, Do you want to use your mac as a heater?

Imagine that you are in cold conference room and you kind of feeling the cold on your head. What do you do when you are in a serious meeting and just can't get out?

If you have a MacBook, you might have a solution.

Use your terminal to run either of these commands to keep your CPU at above 80% or if you want you can run them both.

$ openssl speed

and/or 

$ yes > /dev/null

The first command just outputs the ssl cryptography stats and it keeps your cpu busy. The second command just prints the character "y" into IO.

So try it out and let me know how it works! :D
