Embedded Limbo Dancing with Wasm - Dominik Tacke, Siemens AG & Keith Winstein, Stanford University
Monday November 11, 2024 3:00pm - 3:35pm MST
Ballroom 3
What’s the smallest possible footprint for a WebAssembly application on an embedded device? This talk aims to answer just that. Wasm has some great advantages, including its polyglot nature: the ability to compile multiple languages to the same target, allowing developers unfamiliar with embedded C to program tiny devices, and dynamically load applications on target devices. But this comes at a cost: the footprint of the runtime and the overhead of our chosen languages. What if we could reduce this overhead to the bare minimum? A less-well-known but valuable Wasm feature is that (unlike with Java, JavaScript, Python, etc.) Wasm’s “runtime” can be extraordinarily minimal—almost zero in size. Join as we demonstrate how to make a Wasm runtime“limbo dance”, reducing its overhead to under 5 kilobytes of ROM and a few hundreds of bytes of RAM, and even lower still with some sacrifices.

Bootstrapping Ecosystems: Unveiling the Power of the Component Model - Oscar Spencer, F5 NGINX
Tuesday November 12, 2024 11:00am - 11:35am MST
Ballroom 2
The WebAssembly Component Model promises many things, but one of the most exciting promises is cross-ecosystem component composition. You're able to choose the right source language for various aspects of your application, whether that's Rust for zippy media codecs, Go for its excellent cryptography stack, or a high-level language like JavaScript for your business logic. The Component Model proves itself invaluable for budding ecosystems like that of the Grain programming language. Developers who have wanted to use Grain to write WebAssembly but found the ecosystem of libraries not yet mature enough are now able to depend on libraries from any language ecosystem. In this talk, we'll explore what's possible with composition through the Component Model, how developers use it today, and where it can help you in everyday development.

Whamm! A WebAssembly Bytecode Instrumentation DSL - Elizabeth Gilbert, Carnegie Mellon University (CMU)
Tuesday November 12, 2024 11:45am - 12:20pm MST
Ballroom 1
Debugging and profiling programs is done through instrumenting the program-under-observation (inserting instructions to monitor dynamic execution). The most-common techniques inject instructions directly into the program. While this enables tools to support any domain, it intrudes on the program state space, complicates the implementation, limits the scope of observation, and cannot dynamically adapt. These issues can be remedied by interfacing with an engine, like Wizard, with instrumentation support. A recent ASPLOS paper demonstrated how to build support that protects the application, provides consistency guarantees, applies JIT optimizations, and more. However, this technique limits a tool's scope to programs that can run on such engines. This talk presents the design of a new instrumentation DSL for Wasm that abstracts above the injection technique enabling tooling to support a wide domain of applications while leveraging runtime capabilities as-available without reimplementation.

The Future of Green Cloud: Serverless WebAssembly on Arm64 Architecture - Kate Goldenring, Fermyon & Aaron Williams, Ampere Computing
Tuesday November 12, 2024 1:30pm - 2:05pm MST
Ballroom 3
The software carbon intensity (SCI) of an application is the sum of its operational and embodied emissions. Serverless provides a path towards reducing operational emissions by running event-driven applications only as needed. However, traditional serverless platforms face limitations due to slow startup times of MicroVMs and containers. WebAssembly (Wasm) addresses this with sub-millisecond startups, lowering SCI. Furthermore, Wasm is platform-agnostic, enabling applications to be built once and run anywhere, continually optimizing for the greenest architecture, such as Arm64. Ampere Arm64 CPUs use 2.8x less power than equivalent x86_64 CPUs, offering lower SCI by improving "performance per watt”. This talk will cover the sustainable features of Wasm and Arm64 and demonstrate deploying serverless Wasm applications on Kubernetes using open-source tools Spin and SpinKube. By the end, you’ll understand how to leverage Wasm and Arm64 for a cost-effective and sustainable cloud.

wRPC: Distributed Components, No Assembly Required - Roman Volosatovs & Taylor Thomas, Cosmonic
Tuesday November 12, 2024 1:30pm - 2:05pm MST
Ballroom 1
One of the most beloved features of the component model is extensibility. As the WebAssembly ecosystem continues to grow, the WebAssembly community will need extensibility beyond component composition to build everything from plugins to fully distributed microservices and everything in between. This is where wRPC (WIT-RPC), a WebAssembly component-native, transport-agnostic RPC protocol and framework comes in. wRPC facilitates WIT (WebAssembly Interface Type) defined composition over network, IPC, or other means of communication. What this means is every WebAssembly component can be used with wRPC out-of-the-box using your execution model of choice. This talk will discuss why wRPC exists, the design behind it, and how you can integrate it with your WebAssembly runtimes and platforms. Through many diagrams and demos, you’ll learn why wRPC is important and how it can be used to create reusable, language-agnostic plugins and distributed component communication.

WASI to Go: Write Once, Go Anywhere - Jiaxiao Zhou, Microsoft & Randy Reddig, Fastly
Tuesday November 12, 2024 2:15pm - 2:50pm MST
Ballroom 2
Go is loved by developers for its simplicity, concurrency and efficiency. This talk explores how Go developers can quickly and easily build Wasm components for cloud-native workloads using new and existing open-source tools: * Generate idiomatic Go bindings for WebAssembly components using `wit-bindgen-go` * Compile a component with TinyGo * Run the component with Wasmtime The audience will learn how to use these tools to build a portable and language-agnostic WebAssembly component to handle HTTP requests using the emerging `wasi-http` standard. This talk concludes with a discussion on areas for improvement to enhance the Go developer experience for building WebAssembly applications.

Do More in the Browser with Wasm Components - Calvin Prewitt, JAF Labs & Mendy Berger, Renderlet
Tuesday November 12, 2024 2:15pm - 2:50pm MST
Ballroom 1
With the Web IDL now available as a Wit package, any programming language can leverage browser APIs, just like JavaScript. Our speakers explain how this works and showcase the exciting possibilities it opens up. Using WASI implementations built for the browser, components running in a Service Worker can intercept outbound HTTP requests, responding in the place of the server. Opening up interesting offline as well as local-first applications.

Behind the Scenes: Debugging Kotlin/Wasm - Zalim Bashorov & Artem Kobzar, JetBrains
Tuesday November 12, 2024 3:30pm - 4:05pm MST
Ballroom 2
Kotlin is a modern statically typed programming language developed by JetBrains, designed to be used across different platforms. WebAssembly a portable binary format, designed to be fast and safe, enables running high-performance code in various environments. Combining the two technologies, Kotlin/Wasm allows developers to write efficient and portable code that can be executed in any Wasm-enabled environment and build from high-performance web applications to serverless functions. In this talk, we’ll explore existing debugger capabilities when targeting Wasm from a user point of view. Then, we will go behind the scenes of Kotlin/Wasm tooling and look at internals allowing debugging Kotlin inside WebAssembly.

FaaSter: Performance Adventures Serving HTTP with WebAssembly - Alex Crichton, Fermyon
Tuesday November 12, 2024 3:30pm - 4:05pm MST
Ballroom 3
A common WebAssembly use case is to handle HTTP requests using short-lived WebAssembly instances. This talk explores optimizations like Wasmtime's pooling allocator, the use of Intel MPK, and virtual memory tricks Wasmtime uses to optimize instantiation. Attendees can expect to hear some rough "rules of thumb" for various performance metrics and we'll point them to ways to collect benchmark data themselves.

Contain Yourself: Wasm and the OCI Spec - Taylor Thomas, Cosmonic & James Sturtevant, Microsoft
Tuesday November 12, 2024 3:30pm - 4:05pm MST
Ballroom 1
Sure, we all love Wasm, but how are you actually supposed to deploy and consume it? The OCI Artifact guidance provides a standardized way to build and distribute content of all shapes and sizes. In this session, we’ll introduce you to the Wasm OCI Artifact specification and how you can use it to distribute, discover, and consume Wasm components just like other cloud native artifacts – all while using your existing tooling and controls. In this talk we’ll break down how to package and use Wasm as OCI artifacts, complete with live demos. We’ll show how you can use common tooling to pull the same Wasm component from a registry and run it seamlessly across runtimes such as runwasi and wasmCloud. Plus, we’ll demonstrate how these components fit neatly into dependency management. Join us for a session packed with insights, live demos, and a dash (or two) of humor, as we explore the future of Wasm with the OCI spec.

Lightning Talk: From Server to Client: Ruby on Rails on WebAssembly - Vladimir Dementyev, Evil Martians
Tuesday November 12, 2024 4:15pm - 4:25pm MST
Ballroom 2
Ruby on Rails is a famous “batteries included” framework for the rapid development of web applications. Its full-stack promise comes in a server-oriented, or HTML-over-the-Wire flavor: a server oversees everything from database interactions to your application UI/UX. And whenever there is a server involved, the network and its unpredictability come into play. No matter how much you enjoy developing with Rails, it would be hard to achieve the same level of user experience as with client-side and especially local-first frameworks. And here comes Wasm. With the help of WebAssembly, we can do a radical shift—bring the Rails application right into your browser, and make it local-first! In my talk, I want to discuss the challenges of making a classic web framework Wasm compatible, the techniques we can use to run server-first applications in the browsers and what are the use cases.
