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.

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.

Can you make your own JavaScript by implementing ECMAScript standard?
You also wouldn't really be creating your own new programing language. You would be creating something that can run JavaScript by following JavaScript standards and syntax. You might be able to add some non-standard features of your own on top of those standards, or include your own standard library of helpers or utilities, but you can't completely make a new or alternative language and then load it in the browser (or at least not by reimplementing ECMAScript standards... you actually can make your own language that runs within any Javascript enviroment, if you provide an interpreter or compiler that transforms it into valid JS. Some people have done something like this, eg Elm: https://elm-lang.org/).

What is the best way to present the user the results of Haskell computations?
You should at least have a look at https://elm-lang.org/ it is a pure functional language like Haskell (although with fewer fancy syntax/type classes) but it has some lovely libraries for visualisation and even with plain elm (+ elm-ui) doing string transformations can be easily done.

Building React Components Using Unions in TypeScript
I get it. However, the whole point of using Unions to narrow your types, ensure only a set of possible scenarios can occur, and only access data of a particular union when it’s safe to do so. That’s some of what pattern matching can provide, and 100% of what using switch statements in TypeScript with their Discriminated Unions can provide. Yes, it’s not 100% exhaustive, but TypeScript is not soundly typed, and even Elm which is still has the same issue TypeScript does: You’re running in JavaScript where anything is possible. So it’s good enough to build with and much better than what you had.

How to render a basic calendar UI in Elm
The beauty of a language like Elm (and other lambda-calculus / functional programming inspired languages) is that there's very little transformation involved in going from an idea to code. And that seems to have a big impact on getting things done.

Is it possible to write games like Pac-Man in a functional language?
I think the most fun and approachable way for beginners to build games with functional programming is with Elm [1].
See a few (small, demo) games built by the community in [2] .
Notice Elm has abandoned the FRP approach in favor of Model-View-Update [3].

reflex - Interactive programs without callbacks or side-effects. Functional Reactive Programming (FRP) uses composable events and time-varying values to describe interactive systems as pure functions. Just like other pure functional code, functional reactive code is easier to get right on the first try, maintain, and reuse.
