Hi guys, So in episode 7 you were asking about where and how the puts method connects to the computer’s display and writes the output. And in episode 8 you were asking about the times method, how that worked and why it wasn’t implemented with YARV instructions. In both cases, I didn’t go into detail about this in the book because it would have distracted you from the topic at hand, which is how YARV executes your code. (Or in this case, my example Ruby code from the book.)

Both the puts and times methods were written by the Ruby code team, and not by you or me. Both of them are implemented in C code. So when you’re writing a Ruby program, some of the methods you write yourself, but you get many other methods for free because they are part of the Ruby language. Many of the these built in methods are part of the standard library, which means they are Ruby code written by the Ruby core team, while other built in methods are written directly in C code by the Ruby team.

As you know, the puts method tak

# No special OID type is applied to an `interval` type. Rails will treat it as a string, although

If you start to see something like this, e.g. on Heroku since they installed the postgres 9.5 client libraries on their dynos

This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

First let's check something.

brew info postgresql

The top of what gets printed as a result is the most important:
