Symbiotic languages

• L@@k Fast Ruby by Charlie
• CoffeeScript is #11 on Github, wow
• What other runtimes can we target?

Bandicoot

• Very nice, works against sets
• Relational operators

Elm

• FRP
• Inpired by the Kubler-Ross model :-)
• Love the tagged rectangles [markdown| **bolded**]
• Flow model similar to Joc:socks
• Values that change over time are Signals (mouse pos)
• lift pulls a function into the Signal world

Plan (lisp)

• Rails-like model of work (planed)
• UNIX model (planned)

Classless

• http://enumerable.org
• Shen.clj
• Shen’s interop story is weak ATM
• L44k Gilles Deleuze and Felix Guattari
• L44k David Berry

Datalog

Roy

• typeclasses
• deferred errors

• a is generic type

Julia

• multiple dispatch (Dylan)
  • all args considered.
• @macro calls distinguished wth @
• interacting with data is key
• exploratory programming for an exploratory field
• math ops should be functions
• no static type checks, all types should be declared properly
• started as scheme-based interpreter, moved to llvm

Rust

• abstraction penalty
• cost-free penalties: an abstraction that represents a lower-level structure should not cost more than writing out the lower-level structures themselves
• fmt! is the macro syntax tag
• @ pointer type lifetimes are scope bound
  • shared_ptr<T>
• & borrow pointers
  • T&
• ~ meak pointer types are limited in their ownership
  • auto_ptr<T>
• concurrent tasks start with a small stack
  • cheap to make
  • grows as needed
  • individual heaps
• http://smallcultfollowing.com
• http://pcwalton.gitub.com
• irc.mozilla.org #rust
• gdb debugging
• L@@k code duplication vs. virtual dispatch

Break

  • treetruncs
  • pl of differing types
  • zeder
• Patagonia
  • drawings
  • contracts
• core.contracts
• trout

Grace

• Smalltalk inspired

Elixir

• elixir-lang on freenode

• no interop cost
• inspired by Clojure
• distributed computation across named processes

Visi

• Excel programming
• L@@k Mesa and Integer spreadsheets
• Improv separated formulas from data
• formula inheritence
• sinks, sources and references
• directly effecting your enivironment
