Practicing Sparrow  Our previous talks "GraalVM-based unified runtime for eBPF & Wasm" at GOTC 2021 (Shenzhen) (Shenzhen) & "Revisiting GraalVM-based unified runtime for eBPF & Wasm" at OpenInfra Days China 2021(Beijing), and the third-round discussion of this topic will come in this year,

compatibility requirements, , and they haven't chosen to lock- in a specific runtime. Why need Tokio? Rust does not provide async runtime in std lib Tokio gets the biggest support from the community, and

Who am I? Still at Microsoft, now on the .NET Core runtime team. • https://github.com/dotnet/runtimeWhat is interoperability? Enabling two or more disparate entities to work together. Don’t touch it Java Native Access (JNA) – 2007 Go – cgo – permit C in the .go source file – 2009 Swift – share a runtime and be like C – 2014There is no one approach. Make it suck less by recognizing assumptions.What

function from a constexpr function. – That the behavior of your constexpr function matches your runtime behaviour (they can diverge). No Work is Less Work Than Some Work 45 |Questions About constexpr/Execution expands the set of functions available to the GPU. • May improve performance by: • Moving work from runtime to compile time. • Making dimensions of vectors/matrices available at compile time. 49 |Concluding

and older, the following compiles: std::string s { nullptr };  but has undefined behavior at runtime!  C++23 prohibits constructing a string or string_view from nullptr  no more undefined behavior56 elements from the original view (sliding window)  Similar to views::adjacent, but window size is runtime parameter for slide()  E.g.: std::vector v { 1, 2, 3, 4, 5 }; auto r7 { v | std::views::slide(2)
