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.

Is Go the best language to build a web page with a collaborative text field?
I'm exploring web stacks to build a multiplayer text editor. Elixir's Delta has been recommended to me.
-
Would you use Phoenix LiveView to build a collaborative text field?
Definitely checkout Slab’s Operational Transform library Delta as well. I think conventional wisdom is that CRDTs can be really helpful when there is no single source of truth (i.e. a server), but OT can simplify things when there is.

Is there an equivalent to Yjs in Elixir's Phoenix?
For the particular goal of text collaboration, there are also operational transforms. There is a library maintained by the folks at Slab: https://slab.com/blog/announcing-delta-for-elixir/

Ask HN: What tech stack would you use to build a new web app today?
Yeah offline or complex client side state management is a good use case for Javascript. There are Hooks and Push Events with Liveview for real time integrations with Liveview in those scenarios. In my experience offline requirements are rare and often in mobile scenarios where a native or Flutter-like approach is a good option.
Complex client side state or collaborative features might use something like https://github.com/slab/delta-elixir or https://www.inkandswitch.com/local-first/ which is where I'd want JS.

Track content and changes with Delta in Elixir
Here's a little context on Delta (https://github.com/slab/delta-elixir) and the linked blog post:
Delta is a format to describe documents' contents and how it changes over time. This is a core piece of technology at Slab, that powers our real-time collaboration engine, thanks to the built-in support for Operational Transform (think multiple users working together in Google docs).
Though we've been using it internally for almost 4 years now, we're finally open-sourcing it to the wider Elixir community.
Would love your feedback!

Interactive Code Cells
I prefer functional programming with Livebook[1] for this type of thing. Once you run a cell, it can be published right into a web component as well.

What software should I use as an alternative to Microsoft OneNote?
If you're a coder, Livebook might be worth a look too. I certainly have my eyes on it.

Would highly recommend looking at Jose's use of livebook to answer these. It makes testing easier. It's old but still relevant. Video link inside

Racket branch of Chez Scheme merging with mainline Chez Scheme
That's hard to say. Racket is a rather complete language, as is F# and Elixir. And F# and Racket are extremely capable multi-paradigm languages, supporting basically any paradigm. Elixir is a bit more restricted in terms of its paradigms, but that's a feature oftentimes, and it also makes up for it with its process framework and deep VM support from the BEAM.
I would say that the key difference is that F# and Elixir are backed by industry whereas Racket is primarily backed via academia. Thus, the incentives and goals are more aligned for F# and Elixir to be used in industrial settings.
Also, both F# and Elixir gain a lot from their host VMs in the CLR and BEAM. Overall, F# is the cleanest language of the three, as it is easy to write concise imperative, functional, or OOP code and has easy asynchronous facilities. Elixir supports macros, and although Racket's macro system is far more advanced, I don't think it really provides any measurable utility over Elixir's. I would also say that F# and Elixir's documentation is better than Racket's. Racket has a lot of documentation, but it can be a little terse at times. And Elixir definitely has the most active, vibrant, and complete ecosystem of all three languages, as well as job market.
The last thing is that F# and Elixir have extremely good notebook implementations in Polyglot Notebooks (https://marketplace.visualstudio.com/items?itemName=ms-dotne...) and Livebook (https://livebook.dev/), respectively. I would say both of these exceed the standard Python Jupyter notebook, and Racket doesn't have anything like Polyglot Notebooks or Livebook. (As an aside, it's possible for someone to implement a Racket kernel for Polyglot Notebooks, so maybe that's a good side project for me.)
So for me, over time, it has slowly whittled down to F# and Elixir being my two languages that I reach for to handle effectively any project. Racket just doesn't pull me in that direction, and I would say that Racket is a bit too locked to DrRacket. I tried doing some GUI stuff in Racket, and despite it having an already built framework, I have actually found it easier to write my own due to bugs found and the poor performance of Racket Draw.

Runme – Interactive Runbooks Built with Markdown
This looks very similar to LiveBook¹. It is purely Elixir/BEAM based, but is quite polished and seems like a perfect workflow tool that is also able to expose these workflows (simply called livebooks) as web apps that some functional, non-technical person can execute on his/her own.
