Phlex for Rails Emails: Action Mailer Without ERB (camillovisini.com)
Writing Ruby all day is fun, but writing Ruby in HTML is not. In the past months, I found switching from Ruby to ERB views and partials to be interrupting my flow and therefore increasingly annoying. Enter Phlex, which is a Ruby library that allows you to write HTML (components, views, layouts) in pure Ruby. After already completely ditching ERB for Phlex in Rails views for multiple applications, I wanted to see if I could do the same for Action Mailer.

The Mythical IO-Bound Rails App (byroot.github.io)
When the topic of Rails performance comes up, it is commonplace to hear that the database is the bottleneck, so Rails applications are IO-bound anyway, hence Ruby performance doesn’t matter that much, and all you need is a healthy dose of concurrency to make your service scale.

Rails 8.0 Beta 1: No PaaS Required (rubyonrails.org)
Deploying modern web apps – with all the provisions needed to be fast and secure while easily updateable – has become so hard that many developers don’t dare do it without a PaaS (platform-as-a-service). But that’s ridiculous. Nobody should have to pay orders of magnitude more for basic computing just to make deployment friendly and usable. That’s a job for open source, and Rails is ready to solve it.
