F# Londoners
F# Londoners is a meetup group that aims to bring together Londoners with an interest in programming with F#.
Topics include:
- Essentials of functional programming and F#
- Assessing what kind of projects F# is well suited for - or not
- Using F# alongside other languages and libraries
- Asynchronous and parallel programming
- Data visualisation
- Scientific programming
- Numerical methods and optimisation
- Financial modelling
As an affiliated user group of fsharp.org, the F# Software Foundation, we strive to build a great community of passionate people who care deeply about F#, and want to make our community a safe and welcoming place for everyone. We expect everyone attending our events to be respectful, open, and considerate, and to follow the F# Software Foundation Code of Conduct. If someone's behavior makes you feel uncomfortable or unsafe in any way, please report the issue by emailing conduct@fsharp.org.
Sorry, looks like F# Londoners haven't got any events scheduled for the moment!

Prisoner's Dilemma Coding dojo with Tomas Petricek
Featuring Tomas Petricek
We will spend the evening writing game strategies for the "iterated prisoner's dilemma" problem. This is a simple round-based game with two players. In each round, each player can choose to cooperate with or betray the other play. If you betray but the opponent cooperates, you win 3...

Type-Safe Datatype-Generic Programming in F#
Featuring Nicholas Cowle
Datatype-generic programming is a powerful technique that allows you to parameterise your functions by the shape of the types that they are invoked with. A simple example of datatype-generic programming is a pretty-printer for arbitrary record types – it inspects the structure of the record type...

GraphQL: May the Best API Win!
Featuring Jorge Gueorguiev Garcia
Jorge loves REST, but found GraphQL interesting and decided to investigate. After working on his first production GraphQL API, he has pitted them against each other in a bout over three rounds, to compare their qualities and advantages. May the best API win!

Geometric Algebra in F#
Featuring Andrew Willshire
Geometric algebra has been proposed as a unifying mathematical framework for physics. Proponents claim that it provides compact and intuitive descriptions in many areas including classical and quantum mechanics, electromagnetic theory and relativity. GA has also found use as a computational tool...

Introduction to Markov Chains in F#
Featuring Mariusz Wojcik
A Markov Chain is a stochastic model describing a sequence of possible events, in which the probability of each event depends only on the state attained in the previous event. There are many examples of Markov processes including Google's PageRank algorithm, thermodynamic models and automated...

Initial Algebras for the Uninitiated
Featuring Nick Cowle
The concept of the initial algebra, borrowed from Category Theory, is a simple but powerful one that allows you to completely separate the description and interpretation of your APIs. In this talk, we'll find out what exactly an initial algebra is, along with how to define and create your own...
