Join Charles Hoskinson in this insightful keynote from the Tech for Impact conference in Japan, where he explores the transformative potential of blockchain technology in reshaping our economic, political, and social systems.

Charles challenges us to rethink the world we live in and explore how cryptocurrencies can realign incentives. He also emphasizes the critical need for governance in leveraging these technologies responsibly, ensuring they serve future generations.

ABSTRACT This talk and workshop/jam will introduce you to PureScript, a strongly-typed, Haskell-inspired programming language that compiles to JavaScript. These sessions will focus on building a small game in incremental steps, from simple functions to a web-based app, giving you a chance to try out features and libraries along the way. You should leave the session with a grasp of PureScript fundamentals, and a self-sufficiency to tackle your own projects and experiments.

Appropriate levels of physical activity, sedentary behaviour and sleep (collectively termed movement behaviours) are essential for the healthy growth and development of preschool-aged children.

This was the impetus for creating the Canadian 24-Hour Movement Guidelines for the Early Years (birth to four years). Likewise, this is why the World Health Organization adopted the Canadian guidelines when creating the global guidelines on physical activity, sedentary behaviour and sleep for children under five years of age.

Considering the extensive benefits of movement behaviours, it is very alarming that a recent study found that only 14 per cent of preschoolers around the world are meeting movement behaviour guideline recommendations.

The most recent release of GHC includes a technology preview of a WebAssembly backend. This allows Haskell code to run in many new contexts.

GHC's WebAssembly backend is based on an earlier research compiler called Asterius. In this talk, Cheng Shao, the main author of both projects, presents an introduction to WebAssembly and why compiling Haskell to it is different than other platforms. The talk includes many details about why the backend is the way it is, along with instructions to work on it.

This talk was presented at the 2023 GHC

Contributor's Workshop in Rapperswil, Switzerland, colocated with Zurihac. The workshop was arranged by the Haskell Foundation, OST Eastern Switzerland University of Applied Sciences, and the GHC development team.

Cheng Shao is a full-time software engineer at Tweag, where he has been working since 2018. His main contribution to GHC is the WebAssembly backend, which grew out of his early research project, a Haskell-to-WebAssembly compiler codenamed Asterius. He focuses on maintaining the GHC WebAssembly backend, adding new functionality, as well as other GHC work that involves code generation and the runtime system.
