Virtual Threads for Lightweight Concurrency and Other JVM Enhancements

Concurrent applications, those serving multiple independent application actions simultaneously, are the bread and butter of server-side programming. The thread has long been software’s primary unit of concurrency, and has also served as a core construct for observability and debugging, but its cost was such that it could no longer efficiently represent a domain unit of concurrency, such as the session, request or transaction. As a result, various languages have seen a proliferation of both libraries and language constructs that offer scalable concurrency by abandoning the thread as the unit of software concurrency.

This talk will present how and why Java abstracted its existing thread construct to provide an alternative user-mode implementation of threads as opposed to offering a new concurrency construct. We will also briefly mention other transformative features recently added to the JVM in the areas of garbage collection and observability/profiling.

Wasm: What is Universal Compute Good For?

Tuesday Jun 13 / 10:35AM EDT

WebAssembly represents the future of portable computing, providing an efficient and secure runtime for many languages. In the last year there has been an explosion of growth in Wasm on the backend, from managed platforms, tooling, and further standardization work around WASI.

Build Features Faster With WebAssembly Components

Tuesday Jun 13 / 01:40PM EDT

Wasm modules revolutionized portable application code. For the first time, they allowed us to write in a high-level language - like Go or Rust - and then target WebAssembly as the platform-agnostic bytecode.

Achieving SLSA Certification with a “Bring-Your-Own-Builder” Framework

Tuesday Jun 13 / 04:10PM EDT

Supply-chain Levels for Software Artifacts, or SLSA (pronounced “salsa”), is a security framework to reason about and improve the integrity of released artifacts. With the recent release of SLSA version 1.0, SLSA is seeing increased adoption, both from industry and open source projects.
