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.

Need help designing architecture to handle API rate limit
rack-throttle is usually used to throttle incoming requests, but it has a generic [Second](Rack::Throttle::Second) class which could be used to throttle any operation to a maximum number per second. It stores its counter in either redis or memcache, which will work as the shared store and be performant.

How to Use Sinatra to Build a Ruby Application
Because of its lightweight and Rack-based architecture, Sinatra is great for building APIs, mountable app engines, command-line tools, and simple apps like the one we'll build in this tutorial.

Building a Ruby app without any framework
Since you mentioned Sinatra and Rails I assume you're talking about web apps. In that case you want to build a Rack Application. That's where web frameworks' responsibility ends.

Ask HN: Release Notes
I'm thinking about building a website that scrapes release notes from sources like https://community.ui.com/releases, https://github.com/rack/rack/blob/main/CHANGELOG.md, https://developer.android.com/about/versions/13/release-notes etc, and cleans them up & formats into the same format so they can be searched a lot easier.
It seems like the best place to start would be for folks who read HN since we refer to these quite a bit day-to-day to figure out what changes in software, apps, etc. Let's open this up with a few questions:
1. Would you find a service like this useful? Why or why not?
2. What release notes would you want to have formatted into the same thing and why?
3. What features or capabilities would you like to see a service like this do? e.g. would you like to select multiple "products/apps/whatever" and see their release notes in one timeline? Side-by-side? etc. etc. etc.

Elixir Plugs
In Elixir world, Plug is a bit similar to Rack in Ruby. Official documentation describes Plug as:

The spec for Ruby's Rack is another good reference for how a Ruby webserver is expected to work.

The Definitive Guide to Rack for Ruby and Rails Developers
You've been around in the Rails world for a while. You know your way around rails. But you keep hearing this word 'Rack' and don't really understand what it is or what it does for you. You try to read the documentation on the Rack Github repository or the Rails on Rack guides, but the only thing it does is add to the confusion.

Crafting mini RubyOnRails
Begin with writing a rack-middleware. Rack is a standard library for writing a web server. The main structure is simple. Here is an example:

Request Coalescing in Async Rust
Coming from the Ruby ecosystem, a lot of this played out similarly to how the Rack[1] middleware conventions developed in the early Rails v1 and v2 days. Prior to Rack there was a lot of fragmentation in HTTP server libraries, post-Rack everything more or less played nicely as long as libraries implemented Rack interfaces.
I don't write Rust professionally, but it was a bummer seeing that this seems to be a place that was figured out (painfully) in ecosystems used heavily for web development--Javascript and Elixir have their own Rack equivalents[2][3]. I hope that Tower plays a similar role to unify the library ecosystem in Rust.
