News includes a new library called Lotus and LotusWeb that provides a safe, read-only environment for running SQL analytics queries with organized storage for saved queries. After the news, we had an interview with Mateusz Front about the Popcorn project, which enables Elixir to run in WebAssembly (WASM) in the browser courtesy of AtomVM. We dig into how it works, what it's capable of doing, and where it could go in the future!
