| # I tried a bunch of different things, and as usual it's simple, but you have to get it right. | |
| # The important part is that you have to shell with /bin/bash -c and source nvm.sh | |

Sometimes you need to iterate over a ton of items and you don't want the overhead of creating AR objects out of all of them. Hell, you only need a few things! Well, #pluck has your back.
But what if you want to iterate over many tonnes of items?
Pluck in batches to the rescue!
This isn't the exact code that I use in my code base, but it is damn close.

psql -U postgresSome interesting flags (to see all, use -h or --help depending on your psql version):
-E: will describe the underlaying queries of the \ commands (cool for learning!)-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com, example2.com, and example1.com/images on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
