F# in the Open Source World

@dsyme, Principal Researcher, Microsoft ResearchF# Community Contributor

This talk has some slides provided by other people

Ill try to remember to tell you when thats the case

Agenda

A tour through our broadening horizons

Ecosystems, Exosystems and The Digital World

Some initial thoughts on a new F# open initiative

Part I

F# is changingin subtle but important ways

F# runs on many platforms

F# is for Windows

Overview


F# has many contributors

Microsoft makes F#

Overview


F# isone language with many tools

F# is part of Visual Studio

New think

http://fsharp.org

Why do Microsoft contribute to F#?

functional-first
=
simple code to solve complex problems
=
improved time-to-market for code-heavy programming

better programmability
=
better platforms
=
make money

functional-first
=
simple code

Lets just remind ourselves about that

Now lets look more broadly

Some latest news

Part I: Summary

F# is open source, cross-platform with many contributors

The core compiler and library are done at Microsoft using a code drop model

The fsharp.org community are OK with that

The F# Exosystem is big, rich, active and multi-faceted

To discuss:

Is this the right way forward?
If so, could you be involved?
How would we make this happen?
What other design principles?
Can you contribute to components today?

Through the wonderful lens of FP

Originally .NET+Visual Studio

Now a broader, community-led vision

F# is about about leveraging and integrating external functionality F# as a Language: FF + interop

F# at Microsoft: tooling, platforms, data

F# broadly: many, many things going on!
