That's what we covered in this episode?

More RAM would help you run more Rails processes at once so you could serve more users at once, but each individual request will still need to be optimized to run as quick as possible. Caching & optimizing assets is still important and a bigger CPU can help process requests slightly faster.

You can use a turbo stream to insert the flash message into a div for them. 👍

I'm actually going to do a screencast on this shortly.

If it's just something simple like product IDs, you could use redis. Rails now has kredis which you can use for that: https://github.com/rails/kredis I've been meaning to do a screencast on it.

If it's more complicated, you probably want to store in your database. Redis is just for simple key / value storage so you can't store anything too complex in there. You can sort of cheat and save a json object as the value, but then you have to de/serialize that every time you access it.

Guess it kind of depends on what you're doing as to what would work best.

It's looking for an SMTP server running on your machine on port 25. You'd have to run something like postfix to do that.

Looks like maybe Rails UJS isn't firing the request as a PUT. I'll take a look and see if I can reproduce it. 👍

Great work Mike! URL shortener is such a fun project to build in Rails. 👍

The Rails 6.0 to 6.1 is really simple, so you should be fine upgrading. 👍

The update task is pretty easy: bin/rails app:update

And of course, all the details are here: https://guides.rubyonrails.org/upgrading_ruby_on_rails.html

Make sure you're using the latest Rails version. I don't think this works in older Rails versions.

I just updated this lesson for Omniauth 2.0. 👍

This episode has been updated for Omniauth 2.0. 👍

Two options that come to mind are:

1. Have the link go through your Rails app, track the click, and then redirect to the URL (also get to hide the URL this way)
2. Use Javascript to record the event on click (you could use Google Analytics, Mixpanel, Ahoy, etc)

You can cancel your subscription in the Billing section of your account.

Using RVM is just fine! Don't worry about switching to rbenv if you're already on RVM.

Post this on the Pay issues. 👍

The timing widget on the page is Rack Mini Profiler: https://github.com/MiniProfiler/rack-mini-profiler

You can query the database if you are using the database delivery method.

Turbo:load runs when a page loads, not a frame. It's the same as the old turbolinks event. Frames are independent from page views which means you need to setup a Stimulus controller instead.

Check out stimulus-flatpickr and you won't have to build anything. 👍

No screencast yet, but their readme is pretty well documented. 👍
