Beijing Elixir Meetup Recap: Elixir Meets Rust, Phoenix LiveView, Bits & Bytes, and FoundationDB

The Tubi‑initiated Beijing Elixir Meetup, held online in May, brought together developers and enthusiasts to share practical experiences and underlying principles of modern Erlang/Elixir technologies.

Elixir meets Rust – by Chen Tian : Chen demonstrated how to bridge Elixir and Rust using Rustler‑written NIFs, achieving a 20‑30× performance boost and presenting a solution to prevent NIFs from blocking the BEAM scheduler. Detailed slides are available on GitHub.

Phoenix LiveView – by Chen Yiming : Chen introduced the popular Phoenix LiveView framework, showcasing several demos, discussing its advantages and drawbacks, and explaining its implementation details. The full presentation can be found on his blog.

Bits, Bytes, String and Emojis in Elixir – by Qiu Hua : Qiu explained the differences and similarities of bits, bytes, strings, and emojis in Elixir, demonstrated elegant binary and string handling, and explored how these concepts map to the EVM. Slides are linked to SpeakerDeck.

FoundationDB and Elixir – by Jiang Jiacheng : Jiang gave an in‑depth look at FoundationDB’s architecture and performance characteristics, then described how to integrate it into the Erlang/Elixir ecosystem. The presentation material is shared via a Baidu Cloud link.

The meetup was praised for its rich technical content, thorough explanations of both practical applications and low‑level mechanisms, and an engaging Q&A session. Recordings are available through the Beijing Elixir Meetup WeChat group, and future events can be followed via the “比图科技” public account.
