   In-Browser Graph RAG with Kuzu-WASM and WebLLM▲158

   We show the potential of modern, embedded graph databases in the browser by demonstrating a fully in-browser chatbot that can perform Graph RAG using Kuzu (the graph database we're building) and WebLLM, a popular in-browser inference engine for LLMs. The post retrieves from the graph via a Text-to-Cypher pipeline that translates a user question into a Cypher query, and the LLM uses the retrieved results to synthesize a response. As LLMs get better, and WebGPU and Wasm64 become more widely adopted, we expect to be able to do more and more in the browser in combination with LLMs, so a lot of…

   AllyDB – An in-memory database similar to Redis, built using Elixir▲20

   Hey, everyone. I am currently working on AllyDB, which is basically my own Redis, which I am writing in Elixir. Currently, the database is nowhere close to being ready, as you can see in the roadmap, but I am doing my best to add stuff as fast as possible. Currently the implementation is very simple, with an in memory table, an append log persistence system, as well as an interval persistence system as a backup. The database could definitely be optimized further, especially when it comes to persistence, which I am planning to do in the future. I'm also planning to use Rust NIFs for specific…

    Topical – Elixir library for synchronising state to web clients▲8

    Hi HN. I've been working on an Elixir library for synchronising state, maintained by the server, to connected web clients. I found this was something I kept implementing for side-projects, so I've extracted it into a library. It solves a similar problem to Phoenix LiveView, but aimed at a different level of abstraction: rather than synchronising HTML and UI events, this just synchronises (JSON-serialisable) state. Topics can be shared between connected users, and each client can subscribe to multiple topics. The library takes care of starting topic instances (GenServer processes) as needed,…

    SirixDB – Storing and Querying of Temporal Data (Java and Open Source)▲13

    I'm developing a storage system for versioning data at the subfile level, especially well suited for SSDs due to its log-structured COW nature. It implements a novel versioning algorithm called sliding snapshot, a diff-algorithm which makes use of our stable record-identifiers and optionally hashes, another diff algorithm for importing similar XML-documents as a versioned resource as well as novel XPath axis to navigate not only in space, but also in time. Recently, I've implemented a higher level, asynchronous REST-API with Kotlin (Coroutines) and Vert.x in a seperate module. The system is…
