> Somehow, it is slower. Clicking on a conversation takes 0.5-1.0 seconds to load it, compared to almost instant load on Classic.
This was an Android specific bug which was fixed a few weeks ago; EXA should now be instant as it should be, at least on nightlies: it was stuff surrounding https://github.com/matrix-org/matrix-rust-sdk/pull/5841. Unsure if the fix has made it into a build yet.
> Conversations are sorted by... who knows. It is not recent nor alphabetical.
It should be by recency.
> Onboarding is bad
Sorry, but you have to run an auth server (matrix-authentication-service) if you want Element X to work.

- Project mention: How I Built an Agentic RAG Application to Brainstorm Conference Talk Ideas | dev.to | 2025-07-08
I used a mix of tools to build this project, each handling a different part of the process. Google ADK helps run the AI agents, Couchbase stores past Kubecon talks data and performs the vector search, and Nebius Embedding model for generating embeddings and LLM models (Example: Qwen) generates summaries and talk abstracts.

- Project mention: Show HN: Mixing Deterministic Codegen with LLM Codegen for Client SDKs | news.ycombinator.com | 2025-08-26
Hi HN, I’m Patrick. Elias, Kevin, and I are building Sideko (https://sideko.dev), a new type of code generator for building and maintaining API client SDKs from OpenAPI specs.
Our approach differs significantly from traditional SDK generators in that we use structured pattern matching queries to create and update the code. Other SDK generators use templates, which overwrite custom changes and produce code that looks machine generated.
We’ve mixed in LLM codegen by creating this workflow: Run deterministic codegen to establish the SDK structure. Let LLMs enhance specific components where adaptability adds value and include agent rules files that enforce consistency and correctness with type checking and integration tests against mock servers. The system will retain the LLM edits, while the rest of the SDK is automatically maintained by the deterministic generator (keeping it in sync with the API). LLMs can edit most the files (see python rules and typescript rules).
You can try it out from your terminal:

We had already integrated a feature-flagging library called Flipt which would segment users based on their session.
