WebAssembly (abbreviated Wasm, a contraction of “WebAssembly”, not an acronym, hence not using all-caps) is a safe, portable, low-level code format designed for efficient execution and compact representation. An assembly is a group of people gathered together in one place for a common purpose. In this show with the whimsical name WasmAssembly (get it?), Thomas Steiner, Developer Relations Engineer at Google, chats with experts from the community about the past, present, and future developments happening in the world of WebAssembly.

    CG, WG, W3C, Lively—Wasm standardization with Thomas Lively - WasmAssembly

    In this episode of WasmAssembly, host Thomas Steiner welcomes Thomas Lively from Google, the new co-chair of the W3C WebAssembly Community Group. Taking over the role from past guest Deepti Gandluri (episode #2), we seize the opportunity to ask Lively the exact same three questions we posed to Deepti—listen back to compare their perspectives! In the second half, the two Thomases dive deep into the proposals Lively is personally championing, covering Custom Descriptors and JS Interop, and the highly-anticipated Shared-Everything Threads.   Chapters: 0:00 -  The Wasm team "Thomas" confusion 0:57 - Thomas' way into Google's Wasm team  4:10 - Wasm CG vs. Wasm WG  9:39 -  Is Wasm standardization moving slowly? 17:58 - Wasm at Google and the Chrome team  22:33 - The Custom Descriptors and JS Interop proposal  35:02 - The Shared-Everything Threads proposal  43:28 -  Wasm, but not Resources: Thomas Lively on LinkedIn → https://goo.gle/45U8uRA  WebAssembly Community Group → https://goo.gle/3K0qSj3  From asm.js to Wasm with Emscripten creator Alon Zakai → https://goo.gle/47zQTj9  CG, WG, W3C, Deepti—Wasm standardization with Deepti Gandluri → https://goo.gle/4ndWX5X  Custom Descriptors and JS Interop → https://goo.gle/4ggStbY   WebAssembly threads →​​ https://goo.gle/45Z0kaI  Shared-Everything Threads → https://goo.gle/47BnLYG  Thomas Lively on Bluesky → https://goo.gle/4gcm2v8

    Dart, Flutter, and WasmGC with Ömer Ağacan and Martin Kustermann

    In this episode of WasmAssembly, your host Thomas Steiner is joined by Ömer Ağacan and Martin Kustermann from the Dart team at Google. They explore Dart, the language behind Flutter, and how Dart nearly landed in V8 alongside JavaScript, and why Flutter doubled down on Dart and WebAssembly Garbage Collection (WasmGC). Ömer and Martin then share insights on Dart’s performance leap from dart2js to dart2wasm, its potential beyond the browser, and what the WasmGC transition means for developers and the broader ecosystem. Finally, they look at Jaspr, Dart-only web apps, or how different browsers are handling WasmGC. This episode again is packed with sharp technical detail and bold visions for the future of WebAssembly.
