A RAG for Elixir

This is the second part of a series of blog find out on using a local RAG (Retrieval Augmented Generation) system for your team’s codebase without leaking any code or data to third parties.

In this part, we find out how the LLM (Large Language Model) can read and understand Elixir code and start a conversation about the codebase with the LLM 🤖.

An end-to-end ES/CQRS example with EventStoreDB and Phoenix/LiveView

A detailed guide to functional state handling, read/write model segregation and event sourcing built on production experience with EventStoreDB.

It features general awesomeness of asynchronicity and serves as a gateway drug for escaping the transactional fallacy.

Last but not least, it is so long that you can legitimately review it on X with “Too long, didn’t read”!

🎥 Against the Grain by Saša Jurić | Code BEAM Europe 2023 🎥

This talk tells the story of developing a bespoke Kafka client. None of the existing libraries in the BEAM ecosystem fulfilled the needs of the team, and it was estimated that contributing new changes to those projects would be very difficult. At the same time, writing and maintaining a client from scratch would require a lot of time, much more than the team could afford:

Thinking Elixir 204: OTP 27 and Blend for Lib Maintainers

In this episode we sit down with Marcelo Dominguez, the driver behind the new “Blend” library, which assists Elixir library developers in testing their projects against multiple versions of dependencies. Marcelo explains the genesis of Blend and the inspiration from the Rubygem “appraisal.” He discusses how Blend tackles the common headache of dependency version clashes and integrates smoothly with CI systems to isolate and report specific compatibility issues. We learn how it works under-the-hood and helps library maintainers more easily keep their promises of supporting a library used in diverse environments. We cover the motivations, complexities, and real-world applications of Blend and more!
