Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Evaluating More Coverage in Ruby 3.2
Have you wondered how much of the logic in your views is exercised in your test suite? Thanks to this change, now you can see that in tools like SimpleCov.

My First Code Commit in Ruby
My talk is about different best practices - specifically when adhering to them breaks down. One of those best practices is high test coverage. I start to work on the content for my presentation by building the code samples that I want to use in the slides. For the code coverage section, I'm writing some code with some tests. I'm using SimpleCov to generate code coverage results.

Improve Code in Your Ruby Application with RubyCritic
SimpleCov - a tool to check Ruby application code coverage. You can configure it to run alongside your tests. It provides metrics on code coverage so that you can identify what you need to pay attention to and where to invest your time to create better test cases.

How to Improve Code Quality on a Ruby on Rails Application
Use SimpleCov to generate a report of how many statements are covered by your test suite. It won't assess the test suite quality, though.

Ruby's Got You Covered
There are many tools for measuring test coverage, but one is SimpleCov. It also supports branches coverage. To measure coverage of production code, check out Coverband, which you can set up to use oneshot lines mode.

Inherited rails app - what the hell are all these rack timeout lines in the log?
Without seeing more of the app, it's tough to say for certain, but one gem you might find helpful is the [bullet](https://github.com/flyerhzm/bullet) gem -- set this up in the app then start browsing around the app in development. If you have any N+1 queries or other minor optimizations that could be done it will inform you about them.

Understanding N and 1 queries problem
There's a Ruby gem called Bullet that identifies and warns developers about N+1 problems. You can also have it fail tests if detected.
I don't know if the approach is possible with every ORM or if it's just leveraging some Ruby perks, but I can't think of a good reason why you wouldn't use the equivalent everywhere.

Help with N+1 problem.
You might consider adding the bullet gem as a development requirement and see what it tells you, it's generally pretty good at spotting n-queries and letting you know how to fix them.

Understanding and Fixing N+1 Query
As a Rails developer, recently I found Bullet [0] which helps massively in dealing with eager loading. For some reason I expected the framework to manage this sort of thing for me, even when Rails actually does a ton out of the box already. Only while refactoring I picked up on queries dragging performance. Oh well...

How do you find the cause of slowness in your app?
This is good advice, it'll likely pick out some glaring issues right away. I would generally recommend looking at DB queries here too and recommend Bullet, but most software like DataDog, AppSignal etc will often also point N+1 and issues like it out.

In order to find all those N + 1 queries that are slowing down in your application, the community recommends using the Bullet gem.
