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.

Show HN: Light implementation of Event Sourcing using PostgreSQL as event store
I’m addition to the alternatives mentioned, here’s another Postgres-only ES implementation: https://github.com/message-db/message-db

Thalo - Event Sourcing runtime for WASM
Thalo is a new Rust library that provides a runtime for WASM-based event sourcing. With Thalo, developers can compile their aggregates and components into WASM modules and use them in the runtime to handle commands and persist events to an event store. The library is built on top of Wasmtime and Message DB, and uses the ESDL schema language to define aggregates. While Thalo is not yet ready for real-world use, it has the potential to make event sourcing more accessible to a wider range of languages that compile to WASM, allowing for a language-agnostic runtime. Give it a try and let us know what you think! https://github.com/thalo-rs/thalo
Its built on top of Wasmtime for wasm execution, and MessageDb which is a message store for Postgres.

Announcing our Elm/Haskell app in production!
We are using message db which is uses postgres under the hood, and provides a few useful postgres functions. We use it with `postgres-simple` and have a small internal library. However my colleague is working on abstracting our logic and open sourcing into a library here: https://github.com/Disco-Dave/message-db

Event Sourcing
Check out MessageDB https://github.com/message-db/message-db. It's basically Postgres and can be installed into any Postgres DB.

Building a Distributed Turn-Based Game System in Elixir
Trying a new language or framework is fun experiments that you spend a few hours on. I have been enjoying implementing Message DB[0] in a hobby project. My current job is not in programming, and not looking for one.

Show HN: Light implementation of Event Sourcing using PostgreSQL as event store
This reminds me of Commanded[0] for elixir which also uses Postgresql by default.

Adding soft delete to a Phoenix Commanded (CQRS) API
So, I lied told a half-truth about aggregates. They are not hydrated in-memory for every command / event. In reality, aggregates are implemented with GenServer each caching their state and being managed under the commanded application's supervision tree (ultimately by a DynamicSupervisor called Commanded.Aggregates.Supervisor, to be specific).

Using CQRS in a simple Phoenix API with Commanded
The Commanded hex package is a fabulous CQRS library used by some real companies in production, but it doesn't have a great on-ramp.

Phoenix LiveView, but event-sourced
The context: I'm building a cryptocurrency exchange application. I don't have the business chops to run an actual exchange, so this is just for fun. The application is built in Elixir, using the Commanded framework for CQRS/ES goodness, and Phoenix LiveView because it's the hot new thing that I wanted to learn.
