DESCRIPTION:\n\nDo you understand Monads and “do notation\,” but still
  do not understand Monad Transformers? Do you want to use a framework or l
 ibrary\, but it has been scaring you off because it uses a monad transform
 er? Then this talk is for you.\n\nThis talk answers two questions:\n- what
  problem do monad transformers solve?\n- how do I use monad transformers t
 o solve that problem?\n\nThis talk will\n- show examples of common monad t
 ransformers and their equivalent “untransformed” versions\n- show how 
 to “sugar” a concrete type into a monad transformer\n- explain why the
  order of monad transformers matter\n- show how to write programs using mo
 nad transformers and their corresponding type classes\n\nThis talk will no
 t explain why monad transformers actually work. But\, it will be easier fo
 r you to learn why they work after watching this talk.\n\nBy the end of th
 is talk\, you will\n- understand when to use transformers\n- be able to us
 e ExceptT\, ReaderT\, and StateT\n- have an intuition for how “Tagless F
 inal” works\n

DESCRIPTION:\n\nWhen reading a byte stream over the process I/O boundary\,
  the first thing which everyone should do is to parse the byte stream with
  a monadic parser.\n\nThe talk will discuss\n\n    Processes and input byt
 e streams.\n    Monadic parsers. What they are and why they matter.\n    T
 he design and use of the purescript-parsing library.\n    How to use monad
 ic parsers instead of regular expressions with the purescript-parsing-repl
 ace library.\n    When not to use monadic parsers.\n\nThis talk is intende
 d for an audience who has some familiarity with monads and regular express
 ions. This talk is inspired and informed by the essay Parse\, don’t vali
 date by Alexis King.\n\nSlides and script: https://github.com/jamesdbrock/

SUMMARY:The Hills Are Alive With the Sound of Comonads

DESCRIPTION:\n\nComonads famously project computations into future context
 s. But what if the future is uncertain? What if\, like in Demolition Man\,
  the computation wakes up in a hostile\, dystopian 2032? Instead\, we’d 
 like the computation to wake up in a place more like Encino Man\, or at le
 ast An American Pickle.\n\nThis was the starting point for purescript-wags
 \, a web audio engine that projects future audio states onto the mutable a
 nd referentially opaque Web Audio API. In this talk\, I’ll show how exis
 tential types can be used inside of cofree comonads to add a modicum of ty
 pe safety to a mutable-state model\, and I’ll also show how linear types
  can be grafted onto comonads as a zero-cost abstraction to tame the volat
 ile Web Audio API.\n\nAt the end\, I’ll show how this facilitates the re
 ndering of complex audio graphs in a sub-fifteen-millisecond deadline\, al
 lowing for low-latency MIDI and audio applications in the browser like htt
 ps://wags.fm/\, https://whatis.wags.fm/ and https://yap.wags.fm/.\n

DESCRIPTION:n this introductory talk\, we will look at Asynchronous progra
 mming primitives in JavaScript and PureScript from first principles\, as w
 ell as how Purescript creates structure and principled approaches to async
 hronous programming.\n\ntopics to include:\n- Event listeners and observab
 le changes on the DOM and Backend\n- Callbacks\, Promises\, Async/Await\n-
  Purescript approaches: Continuations\, the Aff Monad\, and Fibers\n- How 
 JS asynchronous execution works (the Event Loop)
