Unicorn VS Rack

It's extremely similar to the original OOBGC implementation for Unicorn: https://github.com/defunkt/unicorn/blob/master/lib/unicorn/oob_gc.rb

I want to know what exactly it means when a web server describes itself as a pre-fork web server. I have a few examples such as unicorn for ruby and gunicorn for python.

I've went through a similar journey, with some PHP in the early days, then a lot of Merb/Rack/RoR experience. Though I'd not say PHP is back. I'd avoid it for new projects as there are --IMHO-- much better languages available for free.

What I really liked from webdevt in Ruby was Rack. https://github.com/rack/rack (gosh I prefer the simplicity of the old logo)

And I found a Rack-like architecture in "http4k" https://www.http4k.org

In a way Kotlin can be looked at as a "typed Ruby". Sure Ruby now has optional types, but I believe it's not something easily bolted on later. The whole lang + stdlib should be built in an idiomatic way. Changing the language a lot later usually creates a mess in the stdlib.

The framework http4k delivers is very similar Hono/Dumbo, but it has a Rack built in as well. Also, http4k is make by functional programming enthusiasts. So it clearly separates logic and data.

Small request: Please make Hono clickable in the README!

You can find the full, relatively accessible Rack specification on GitHub.

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.

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.

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.

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.
