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.

Paying Down Technical Debt
Ensure that you have sufficient test coverage. You can use code coverage analysis tools like SimpleCov to gain insight into gaps in your coverage.

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.

I Love Ruby
I believe if you use the `||` operator instead of `or`, then things just work out fine. I agree it is really annoying. But I am pretty sure if you use a tool like RuboCop https://github.com/rubocop/rubocop (a static code analysis tool) then it will catch bugs like this. Note that I am not recommending Ruby. But in my experience if you want to work with a language and it has a community style guide and a linter that enforces it, it will save me some heartache.

code review / feedback for improvement
Adopt some sort of consistent formatting. Your top-level module starts off indented, seems like wasted space. May I suggest RuboCop?

An Introduction to RuboCop for Ruby on Rails
By default, out of the box, RuboCop comes with a default set of pre-configured rules. The documentation will tell you Rubocop's default rules.

Code Reviewing a Ruby on Rails application.
RuboCop is a Ruby static code analyzer (a.k.a. linter) and code formatter. Out of the box it will enforce many of the guidelines outlined in the community Ruby Style Guide. Apart from reporting the problems discovered in your code, RuboCop can also automatically fix many of them for you.

Xeme: I'd value your opinion on my new Ruby gem
But I will encourage you to adopt Rubocop to enforce the style you want, so that if others want to contribute, they can write with spaces and then run rubocop -a and end up with the styling you prefer. Tabs indentation support was added a couple of years back: https://github.com/rubocop/rubocop/pull/7867

Welcome to Rails Cheat Sheet
In my last job I encountered my first Rails codebase ever (mostly REST APIs but a few server-rendered views as well). After the initial chaotic impression of the codebase (it was a startup after all) with all the Rails magic on top, I really fell in love with the framework after a more experienced Rails dev introduced a few key conventions and helpful libraries to the codebase.
Out of those, I’d at least add the RuboCop [1] linter and the BetterSpecs [2] guidelines to this list. Both helped tremendously in eliminating bikeshedding in the team and freeing up brainpower to solve actual problems. The first one helped me learn intricacies of Ruby bit by bit right in my IDE and the latter guided us to write tests in a style that’s easy to maintain and trust.

Ruby 2.7.8 Released
RuboCop had a setting for this but it was removed for Ruby 3 because there are valid reasons to pass a hash into a method, and linting it might break code. Here is the issue referencing the commits where it was removed, if you ever need to do this again you could just find an earlier commit.
What are some alternatives?
Coverband - Ruby production code coverage collection and reporting (line of code usage)
sorbet - A fast, powerful type checker designed for Ruby
Rubocop - A Ruby static code analyzer and formatter, based on the community Ruby style guide. [Moved to: https://github.com/rubocop/rubocop]
Rubycritic - A Ruby code quality reporter
coc-solargraph - Solargraph extension for coc.nvim
undercover - undercover warns about methods, classes and blocks that were changed without tests, to help you easily find untested code and reduce the number of bugs. It does so by analysing data from git diffs, code structure and SimpleCov coverage reports
bullet - help to kill N+1 queries and unused eager loading
Pronto - Quick automated code review of your changes
