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.

I stumbled onto this episode after fantasizing about just such a technology where we could take all of the positives of the Beam and bring them to the amazing OCamL compiler. This guy Leandro is incredibly clever and articulate. I loved his use of the word “free range” to describe a technology later in this podcast. A super interesting episode!

Leandro reminds me of myself (though I’m obviously not quite as bright), getting interested in bleeding edge, space age languages like Idris then dialing back the type astronautiness to more breathable air to achieve things in the real world with languages like OCamL. Enjoy! Hopefully some of you smart people can help push #RIOT forward. It seems like a great idea without peer in the tech world.

A quick, naive AI generated Purescript translation (quickly generated that probably doesn’t work but will help get me started later)

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.

2024-10-05 by GIMP Team

This is a short development update on our progress towards the first release candidate for GIMP 3.0. We recently reached the string freeze milestone. What this means is that there will be no more changes in user-facing text (like GUI labels and messages) so that translators can work on the final translations for the 3.0 release.
