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.

Suggestions for how to reduce memory usage
Wire the memory_profiler into an around_action to identify your bloaty actions.

A Deep Dive into Memory Leaks in Ruby
The memory_profiler gem offers a very simple API and a detailed (albeit a little overwhelming) allocated and retained memory report — that includes the classes of objects that are allocated, their size, and where they were allocated. It's straightforward to add to our leaky program.

Ok y’all. How can we get this kind of real-time memory profiling in Ruby? Does it already exist? Is anyone working on this?

Advanced ActiveRecord Querying - With Benchmarks!
We don't need to rely upon a priori reasoning only, we can use memory_profiles and benchmark_ips to compare the memory consumption and iterations per second of each solution.
-
Is there a more efficient way to do these permutation calculations?
Either https://github.com/tmm1/stackprof for cpu or https://github.com/SamSaffron/memory_profiler for memory. In practice profiling and removing allocations also gives a large perf boost.

Reduce memory consumption with a custom ActiveRecord attribute
Our project has one endpoint which gets called quite often. So, I profiled it with memory profiler and saw a line pointing to hstore.rb.

Client side Git hooks 101
Here's a real life example: Imagine a Ruby on Rails app on which a team of developers are working. The code is hosted on GitLab and all the work is coordinated using GitLab issues. In other words: For every commit, there's an associated issue and the issue number acts as a sort of primary key for documentation, time reporting and so forth. This convention has a few advantages, most notably the ability to easily learn more about how, when and by whom features were implemented as well as how this implementation came to be.

16 Best Ruby Frameworks For Web Development [2024]
Ruby on Rails is regarded as one of the best ruby frameworks. It was the primary language in developing big projects such as Twitter and helped the language boost the community. Often referred to as “Rails,” Ruby on Rails is a web development framework with an MVC control structure and currently running its 6.1 version. The 16-year-old language has dramatically influenced the web development structures and managing databases, web pages, and other components on a web application.

More control over enum in Rails 7.1
In Rails 7.1, a new option _instance_methods is introduced, allowing developers to opt-out of the automatic generation of instance methods for enums. When enum is defined with _instance_methods: false, Rails will no longer generate methods like pending?, processed?, etc.

Ruby on Rails load testing habits
Rails isn't super opinionated about database writes, its mostly left up to developers to discover that for relational DBs you do not want to be doing a bunch of small writes all at once.
That said it specifically has tools to address this that started appearing a few years ago https://github.com/rails/rails/pull/35077
The way my team handles it is to stick Kafka in between whats generating the records (for us, a bunch of web scraping workers) and and a consumer that pulls off the Kafka queue and runs an insert when its internal buffer reaches around 50k rows.
Rails is also looking to add some more direct background type work with https://github.com/basecamp/solid_queue but this is still very new - most larger Rails shops are going to be running a second system and a gem called Sidekiq that pulls jobs out of Redis.

Continuous Deployment with GitHub Actions and Kamal
Kamal is a wonderfully simple way to deploy your applications anywhere. It will also be included by default in Rails 8. Kamal is trivial, but I don’t recommend using it on your development machine.
