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.

New to clojure, where to start?
I found this to be an awesome bridge between reading about the theory and actually writing code that works: https://4clojure.oxal.org/

Babashka Babooka: Write Command Line Clojure
This is for general Clojure, I’ve had a lot of fun and learned a lot from it (and the original): https://4clojure.oxal.org/

Change a variable inside cycle
It's normal to apply methodology like this to clojure when transitioning from other languages. When I was first learning I did a bunch of exercises on 4clojure and my first attempts looked like this. Then I found loop from the standard library and I understood immutability but relied on loop to do anything to collections of things. Eventually, after looking at the answers, I started to get familiar with the standard library. Then my solutions started to look like the two line solution above.

4Clojure is here now: https://4clojure.oxal.org/. It runs locally in your browser.

The best Clojure learning path
Go to https://4clojure.oxal.org/ and solve some stuff. And don't learn any theory. You're thinking how a C# developer thinks and you think you need to learn some kind of packages by heart or something.
-
Building a Startup on Clojure
I learned by reading through a book, then working through problems on https://4clojure.oxal.org/. If you've got JS experience it won't take too much effort to pick up. Don't get too carried away with forming the perfect tail recursive pure functional monad or whatever. Get into just doing what you're trying to do quickly, then after you're competent, read other people's code to correct your style.

learning Clojure
I'm only a couple months into learning Clojure too, but I found solving a problem myself and then seeing others solutions on this website https://4clojure.oxal.org/ was invaluable for learning to think like a clojurist.
-
Anything like 4clojure for Haskell?
I'm trying to learn Haskell and found https://4clojure.oxal.org/ very helpful. https://tryhaskell.org/ was also nice, but it is limited in scope as compared to its Clojure equivalent.

'Interactive Problems' section in the side bar contains a bad link to '4clojure.'

We need to talk about parentheses
Examples (for Common Lisp, so not citing Emacs): reddit v1, Google's ITA Software that powers airfare search engines (Kayak, Orbitz…), Postgres' pgloader (http://pgloader.io/), which was re-written from Python to Common Lisp, Opus Modus for music composition, the Maxima CAS, PTC 3D designer CAD software (used by big brands worldwide), Grammarly, Mirai, the 3D editor that designed Gollum's face, the ScoreCloud app that lets you whistle or play an instrument and get the music score,
but also the ACL2 theorem prover, used in the industry since the 90s, NASA's PVS provers and SPIKE scheduler used for Hubble and JWT, many companies in Quantum Computing, companies like SISCOG, who plans the transportation systems of european metropolis' underground since the 80s, Ravenpack who's into big-data analysis for financial services (they might be hiring), Keepit (https://www.keepit.com/), Pocket Change (Japan, https://www.pocket-change.jp/en/), the new Feetr in trading (https://feetr.io/, you can search HN), Airbus, Alstom, Planisware (https://planisware.com),
or also the open-source screenshotbot (https://screenshotbot.io), the Kandria game (https://kandria.com/),
and the companies in https://github.com/azzamsa/awesome-lisp-companies and on LispWorks and Allegro's Success Stories.

Common Lisp Implementations in 2023
This LispWorks comment on reddit is very interesting:
---
[cite]
As a Lispworks user, yes it is super pricey, but it does make sense for certain people. Arguably, Lispworks provides features that aren't available in any other programming language, Lisp or not.
* Support for just about every platform I can imagine. Yes it's expensive, but if I want to port to a new platform I can pay Lispworks, and get it over with. It'll mostly work without too much changes. It works on Android, iOS, Windows, Linux, Mac, and some really obscure systems.
* Application delivery with tree shaking. May be there are other languages that do this, but I haven't worked with something like this before in my career. (Maybe proguard for Java, but that's very rudimentary compared to LW's delivery). The tool I work on delivers a binary that people need to download during the CI jobs for every run, so having it be 100MB is way too big. After compression, my LW delivered binaries come to around 9MB.
* You mention support being expensive. Actually, for simple support questions LW does a pretty good job of responding back to you. I've asked tonnes of questions over the years, and have not paid for a separate support contract apart from the yearly maintenance contract. I suspect they like people asking questions, because then they fix those bugs and it becomes even more rock solid.
* The documentation is glorious. And in the off-chance that I need to know something that's not documented, I just mail them and they'll respond usually by the next working day.
* Very stable Java support (although the API could be better), let's me use the entire Java ecosystem of libraries when I need it.
* The platform itself is rock-solid. Now SBCL is fantastic, but when I ran my servers on SBCL, I would have a crash every now and then. With LW, I can have my server running weeks (current uptime is a month) with reloading code multiple times a day, and everything is still super stable.
There's more, but I think the rest is more negotiable. For instance, the FLI is a lot more polished than using CFFI, which makes a huge difference in productivity when writing native code. Or the fact that its remote-debugger facility can be used as a very stable protocol to programmatically control a remote LW process. I don't use the IDE btw, so I'm not even considering that. I don't use CAPI either, but I mean to someday.

Paparazzi 1.2 is out
You can avoid having to do the step of recording screenshots if you use a tool like Screenshotbot (https://github.com/screenshotbot/screenshotbot-oss) or Vizzy (https://github.com/workday/vizzy)

How to do screenshot tests on android
There are open source tools to achieve this workflow. I've personally built screenshotbot (https://screenshotbot.io / https://github.com/screenshotbot/screenshotbot-oss), I've also built the screenshot testing infrastructure at Facebook. Workday has open-sourced their own tool at https://github.com/workday/vizzy. AirBnb uses another commercial tool called Happo (https://happo.io). Use any of these services with Paparazzi.

Why go with Paparazzi? Our journey with Android Screenshot Testing
There are a few open source tools to do this: there's a tool I built: https://github.com/screenshotbot/screenshotbot-oss similar to the infrastructure at Facebook, and there's another one built at Workday: https://github.com/workday/vizzy. These are screenshot-library agnostic services to notify you on Pull Requests when screenshots change.

Fun with Macros: Do-File
So, I'm in the process of defining something I'm calling an easy-macro. (You can see the code here, but I'm going to extract this into a quicklisp library once I'm happy with it: https://github.com/screenshotbot/screenshotbot-oss/blob/main/src/util/macros.lisp)

Help with automated website testing, please
I'm the author Screenshotbot (https://github.com/screenshotbot/screenshotbot-oss) , and I think this is exactly what you need. Although the README claims to not support browsers, it does actually support browsers, both in the open source and non open source version. I just need to update the docs.
