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.

Let's write a simple microservice in Clojure
This article will explain how to write a simple service in Clojure. The sweet spot of making applications in Clojure is that you can expressively use an entire rich Java ecosystem. Less code, less boilerplate: it is possible to achieve more with less. In this example, I use most of the libraries from the Java world; everything else is a thin Clojure wrapper around Java libraries.

A new F# compiler feature: graph-based type-checking
I have a tangential question that is related to this cool new feature.
Warning: the question I ask comes from a part of my brain that is currently melted due to heavy thinking.
Context: I write a fair amount of Clojure, and in Lisps the code itself is a tree. Just like this F# parallel graph type-checker. In Lisps, one would use Macros to perform compile-time computation to accomplish something like this, I think.
More context: Idris2 allows for first class type-driven development, where the types are passed around and used to formally specify program behavior, even down to the value of a particular definition.
Given that this F# feature enables parallel analysis, wouldn't it make sense to do all of our development in a Lisp-like Trie structure where the types are simply part of the program itself, like in Idris2?
Also related, is this similar to how HVM works with their "Interaction nets"?

https://www.idris-lang.org/
https://clojure.org/
I'm afraid I don't even understand what the difference between code, data, and types are anymore... it used to make sense, but these new languages have dissolved those boundaries in my mind, and I am not sure how to build it back up again.

Ask HN: Why does the Clojure ecosystem feel like such a wasteland?
As an analogy - my face hasn't changed all that much in a past few years, and I haven't changed my profile picture in those few years. Does it really mean that I'm unmaintained/dead?
> Where can I find latest documentation [...]?
The answer is still https://clojure.org/. And https://clojuredocs.org/ but it's community-maintained so might occasionally be missing some things right after they're released. E.g. as of this moment Clojure 1.11 is still not there since the maintainer of the website has some technical issues deploying the updated version of the website.
For me personally, the best API-level documentation is the source code.
> Where can I find [...] tools / libraries in a easy to use page or section?
There's no central repository of all the available things since they can be loaded from many places (Clojars, Maven Central, other Maven repositories, S3, Git, local files).
But there are community-maintained lists, like the one you've mentioned at https://www.clojure-toolbox.com (fully manual, AFAIK) or the one at https://phronmophobic.github.io/dewey/search.html (automated but only for GitHub). Perhaps there are others but I'm not familiar with them - most of the time, I myself don't find that much value in such services as I'm usually able to find things with a regular web search engine or ask the community when I need something in particular.

Why Lisp Syntax Works
They are written in Java, and implement a bunch of interfaces, so the implementation looks complicated, but they are basically just classes with head and tail fields.

Why I decided to learn (and teach) Clojure
Lisp is not a programming language, but a family of languages with many dialects. The most famous dialects include Common Lisp, Clojure, Scheme and Racket. So after deciding that I was going to learn Lisp, I had to choose one of its dialects.

8 Meta-learning Tips To Grow Your Skills as a Software Engineer
I learned Clojure to implement a plugin for Metabase (the tool my former company used for creating business dashboards). I probably won’t ever use the language anymore in the future, but learning functional programming was fun and eye-opening.

A History of Clojure (2020) [pdf]
* HTTP: Ring is the de facto way to manage HTTP request (see https://github.com/ring-clojure/ring/wiki/Concepts). Jetty and Aleph are common web servers (and https://github.com/clj-commons/aleph) that implement Ring interface.

I Don’t Like Go’s Default HTTP Handlers
> In the HTTP handlers it makes sense that you don't have return values, because: What would you do with that value exactly?
I think that approach used by clojure's ring shows an elegant way to represent http responses https://github.com/ring-clojure/ring/wiki/Concepts#responses. They are essentially structs with the following fields:
status := number
headers := map of string->string
body := stream | string | seq | inputstream
Request handlers are handed a request struct that is similar. The handler is a function that maps a request to a response (it doesn't actually write to streams itself).
I like this style for an http library for a couple of reasons:
1. HTTP resources can be viewed as functions whose domain is the request, and range is the response. Having the abstraction match that makes for really nice code.

what web framework do you use?
While you won't find your Spring here, you will find that many of those web libraries will tend to use or produce Hiccup, return Ring maps or maybe have pipelines built using interceptors. Composing libraries together is usually not that hard, but it does require you to leave the comfort zone of the framework's abstractions to try to understand what is actually happening e.g. when someone makes an HTTP request and something is returned and displayed in the browser.

Microhttp is an event-driven, single-threaded, zero-dependency web server with 500 LOC. Benchmarks on EC2 show 100,000+ requests per second and 50,000+ persistent connections.
On that note, are you able to support everything required by the ring spec?

Can someone help me understand ring's async handlers (specifically, with Jetty)
I've tried to pair down to the simplest example which shows the issue, and raised it here as I couldn't see one you'd already created or similar: https://github.com/ring-clojure/ring/issues/436 This is so that I have something to link to/follow from our side, hope you don't mind, and many thanks for the diagnosis!
