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.

Common Beginner Mistakes with React
We've had great results from our custom built non-pure reactive system (which predates React by a couple of years).
The idea is to have an Observable object that can store arbitrary trees of data (each itself an Observable). UI drawing is generally split into a function call for each DOM element that has children. These functions are executed such that they track the use of observables and will be rerun when they change.
I've more recently, after having suffered React and friends, started creating an Open Source implementation of the pattern we used. Currently, it's mostly still lacking in documentation and marketing, and that's unlikely to change if I'm honest. But this should give you an impression if you're interested:

Curious to know your thoughts about this being an effective non-pure reactive system.

Million
Yes, that's possible and works really well.
I've written this library [1] as a clean reimplementation of a more complex beast we created for a (now dead) startup. Although the reimplementation has only seen very light use, we've used the concept extensively, and it's a joy to use. Take a look at the examples [2].

That people produce HTML with string templates is telling us something
(Note that Rum is also a React wrapper, but you don't have to use that part of it; you can simply use it for static rendering of HTML.)

Common Beginner Mistakes with React
I love React as long as it has a thin skim of clojurescript over top. Rum is the underdog compared to reagent but is still my weapon of choice - https://github.com/tonsky/rum
Was disillusioned when I had to dive into a pure js project using it.
The real benefit, I think, is that you get the well established Clojure idioms around isolating and managing mutable state.
State is stored in a Atom, which is atomically mutated, and reactive components essentially 'subscribe' to updates upon that atom to re render.
The mutations can be handled centrally by a message queue, but really, event sourcing like that is not always needed.

Giving new life to existing Om legacy SPAs with re-om
We've been using re-om during the last 6 months and it has really made our lives much easier. Before open-sourcing it, we decided to extract from re-om the code that was independent of any view technology. This code is now part of reffectory and it might be used as the base for creating frameworks similar to re-om for other view technologies, like for example rum, or even for pure Clojure projects.

Ask HN: Show me your Half Baked project
I've had an in-browser animated meme editor in the freezer for a few years now:
https://www.ultime.me/
The idea came when I wanted to make a simple animated meme, but found it exceedingly frustrating to caption a simple animated gif with nice text options (like outlines). Over time, it's grown to have full keyframe animation for all text and image/video clip attributes, so it is actually pretty capable short of using a desktop video editing/fx package.
That said, the UX is bad and I should feel bad :) . I made the deliberate choice up front to focus on the underlying data model and internal APIs rather than polishing the UI - as such, it is very much an engineer interface. It would be more usable with some demo videos or call-to-action helpers for new users, but really the UX just needs reworked. Especially around animation/keyframing.
On the bright side, the clean data model and content addressable assets leave the path clear to add things like collaborative multi-user meme editing, git like meme-forking(and diffing?), and so forth.
Started it about 3 years ago when I had a period of mostly free time to play. It's been idle for a long time due to starting a family and getting consulting momentum, but I'm intending to make the time this year to polish the UX to the point of general usability and experiment with promotion/monetization. Failing that, I'll probably just open source it and write a couple of blog posts about the internals.
It is more or less a static web app, with no server side function short of some optional stats collection. It's written in Clojurescript/Clojure and uses https://github.com/tonsky/rum as a React wrapper and

pgvector - Open-source vector similarity search for Postgres
pg_cjk_parser - Postgres CJK Parser pg_cjk_parser is a fts (full text search) parser derived from the default parser in PostgreSQL 11. When a postgres database uses utf-8 encoding, this parser supports all the features of the default parser while splitting CJK (Chinese, Japanese, Korean) characters into 2-gram tokens. If the database's encoding is not utf-8, the parser behaves just like the default parser.
