bindata VS Rack

I recently ditched bindata for a self written solution because I couldn't figure out why exactly it leaks memory. According to count objects it creates a shit ton of classes if you read a lot of data and idk why

"Writing an entire custom program" is the best way. Ruby has a nice package called bindata (https://github.com/dmendel/bindata) that works well for this purpose.

For example, I enjoy sim racing, and some of my games provide a network API for things like telemetry data. So I wrote a simple telemetry logger that I use to gather data, which I then mess around with using R Studio. Ruby worked exceptionally well for this because of a cool little library called BinData.

These projects always remind me of binary formats. I've used bindata to work with binary formats coming from UDP streams over a network, and it's very handy to have a layer that encapsulates your expectations about the data you're receiving, combined with an exception handling apparatus.

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.

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.

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:

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.
