If you want a short excerpt of this newsletter containing only some of the images with code, I created one here. But I invite you to read the entire newsletter as it has excellent content 😊.
This edition was created with support from @adrianthedev from Avo for Ruby on Rails (a friendly full-featured Rails admin panel) and from @jcsrb, who sent me recommendations to include in the newsletter.
👉 Schwad shared how quick it is to prototype ideas with Rails 7:
👉 Brad Gessler shared a snippet of code that will help you not leak instance variables in partials in Rails:
You can check a working example on the public project Brad shared on Github.

Here is how it will look like:
Read more about this including the benchmark run in the Ruby master ticket.
👉 Kirill Shevchenko shared code sample about a common useful pattern when using Service Objects to encapsulate initializer in a call on the class:
In the same thread two gems that are helping to do this were shared: serviz and operators-service
👉 Vinicius Stock shared thread with VSCode tips for Ruby:
“CMD + SHIFT + O: fuzzy search symbols on a file” - source
“CMD + T: fuzzy search symbols everywhere” - source
“F2 for renaming local variables, instance variables, methods or constants” - source

I tried to find the original source for this and it appears to be this forum discussion.
👉 Emmanuel Hayford shared a code sample showing how super_method works:
👉 Kirill Shevchenko shared about using retrying in Ruby by using retriable gem:
👉 Marco Roth shared a small and very pre alpha library to transform ERB into Phlex. Source code can be found here and you can play online with it at phlexing.fun:
👉 Shino Kouda shared using `app` and `helper` methods in Rails console:

Check the playground created by Brad on Github for a more detailed explanation of how this works.

👉 Nate Berkopec shared advice about the number of processes per contain and preforking webservers:
And Andrey Novikov added an explanation:
👉 Brad Gessler shared a thread about using your component systems/libraries over for example simple_form or any building gems:
He later on shared some experiments he did with Phlex that will land later in the sitepress.cc.
Here is an example of a Phlex component that will rend a markdown:
You can find the code in his view-playground on Github. Joel suggested in the thread that the result of Rouge to the syntax highlighting is cached, thus having a slight performance improvement when rendering.
👉 Mike Perham asked if anyone is actively working on removing Global VM Lock/GVL (also named Global Interpreter Lock/GIL) in Ruby:
He described the primary use case of this change as regarding Rails app that can’t scale without managing multiple processes.
Here are two replies from Yukihiro Matz and Jean Boussier (please read the entire conversation for more context)
👉 CJ Avilla shared a Github repo where he played with Phlex and Sinatra:
You might want to check this Github Repo created by Ren Guoy where the deploys some Phlex.fun components on AWS Lamdba using Serverless.
👉 David Colby shared that among the biggest changes in Turbo 7.2.0 is the ability to respond to a GET request with Turbo Stream:

A summary of the answers that were written as reply to the question:
🤔 Shopify Engineering asked about:
Here are some answers (including them here does not mean I agree with all of them, but I think they are interesting to think about).
Read the entire conversation, it had some interesting ideas; and I always like to challenge my beliefs/principles and think about what I miss or what I have to learn.
🤔 Simon Willison shared asked about how to explore a CSV file with 100_000 rows
He shared his solution to this question, but there were a lot of ideas in the conversation.

It is worth reading the RFC for this where Sam explains what he tries to achieve and maybe also see the video demo of the current state of this tech where he deploys to fly.io a newly created Rails 7 app. I think (just a personal opinion) that this is very close to a concept that we could name ActiveDeployment.
