Keynote: Why F# Changes Lives

Featuring Kit Eason

In this talk, Kit explains why F# has such a transformative effect on people who use it. Kit established that any programming language can be thought of as a belief system, helping us make sense of and manipulate the world. He explores why F# is such an effective belief system. To prove his case,...

Lightning Talk: Powerline Oriented Programming

Featuring Dennis Grimminck

At Petersburg Consultants in Doorwerth (the Netherlands), they develop in-house software for structural mechanical and electrotechnical modelling of overhead lines, electricity power stations, and underground cables. With the energy transition gaining momentum, data and its transformation are key...

Lightning Talk: JSON (de)serialization in F#

Featuring Vladimir Sapronov

A programming language cannot be widespread without supporting widely used data formats, like JSON. One of the main problems of F# is not the language itself but lack of libraries choice and specifically lack of libraries designed with F# language in mind. This talk will cover how to...

Keynote: Probabilistic Programming: The What, Why and How

Featuring Maria Gorinova

f(x) = y, but y = 5. What's the probability that x =1? Probabilistic programming is the idea of describing probabilistic models as programs, to then automatically infer how our beliefs about model parameters change given observed data. In recent years, probabilistic programming languages...

Simulating Charles Babbage's Analytical Engine in F#

Featuring John Stovin

In the 1840s Charles Babbage proposed, but never built, an entirely mechanical, Turing-complete computer that he called the Analytical Engine.

The designs were sufficiently complete that Ada, Countess of Lovelace (among others), was able to design 'programs' for it; this also means that...

Ask Not What Government Can Do For Tech

Featuring Gina Marie Maini

Taming Types in the Cloud

Featuring Isaac Abraham

Working with cloud-based data sources often means giving up some of the benefits we're used to when working with conventional relational data stores such as schemas and local access.

This talk will focus on how you can make use of F#’s type system in tandem with distant data sources in order...

Functions as Interfaces: Extend Everything!

Featuring Erik Novales

In a functional world, you can often dispense with explicit interface definitions, because a function's inputs and outputs are an implicit interface. Combining this idea with F#'s automatic generalization gives you a powerful tool for easily bolting on useful features, anywhere in your...

Featuring Gina Marie Maini

Lightning Talk: Let’s talk about Types

Featuring Rumyana Neykova

Rumyana will give a (very) brief history of types and will discuss some (new and not that new) type systems, such as session types (types for distributed programs), refinement types (types with predicates). In this talk, she will challenge you to think how (and why) you can stretch the notion of...

Dungeons, Dragons and Functions

Featuring Mathias Brandewinder

Dungeons & Dragons, or D&D, is the grand-daddy of all role-playing games. While playing D&D is great fun, the rules are a bit daunting for the beginner. The basic rulebook, the PHB, clocks in at a solid 300 pages, and can be extended with multiple additional rule sets. This should...

Keynote: The Bottom of the Iceberg: Enabling Data Science Research with F#

Featuring Evelina Gabasova

When you hear terms like data science and artificial intelligence, you probably imagine fitting fancy mathematical models to data. Well, this is only the tip of the metaphorical iceberg of data science. In practice, it is also the part that ultimately amounts to calling a one-line function from...

Build Cross-Platform Mobile Apps Using Fabulous

Featuring Jim Bennett

In recent years there has been a shift in the way websites and mobile apps are being built - moving to architectures with immutable models and virtual UIs based on the MVU (model-view-update) pattern. This has led to great new frameworks like ELM and React for web, and ReactNative for mobile.

Communication Strategies with Programming

Featuring Alfonso Garcia-Caro

Programming has evolved from listing mechanical instructions for a computer to writing gigantic works in evolved languages that sometimes remind their natural counterparts. However, more often than not we forget this connection and look at other fields like Mathematics in the search for models to...

A Fable about Fish

Featuring Einar Høst

This is a live coding session based on a classic 1982 paper by Peter Henderson. The paper shows the decomposition and reconstruction of Escher's woodcutting "Square Limit", a beautiful recursive tessellation of interleaving fish, using functional programming. Einar will define a set...

F#: Write Once, Run (nearly) Anywhere!

Featuring Tomasz Heimowski

F# is becoming more and more universal nowadays. Not only when it comes to problem domain but also to where one can run it. Desktop, Web, Mobile, IOT, Serverless - those are just examples of F# runtimes. For the purpose of this talk Tomasz will steal the (un)famous "Write once, run...

Durable F#unctions

Featuring Mikhail Shilkov

Serverless architecture is the future of the cloud. Initially, the serverless tech focused on running small isolated tasks in response to cloud events. The next evolutionary step is to compose complex applications out of those small components.

Azure Durable Functions provides powerful...

Lightning Talk: Cloud Infrastructure as F#

Featuring Mikhail Shilkov

Modern cloud applications consist of many moving parts, so they are hard to manage without employing Infrastructure-as-Code approach.

Traditionally, tools like CloudFormation, ARM templates and Terraform employ text-based templates, which tend to be tedious, repetitive and difficult to reuse.

From Concept to Creation in a Week with Fabulous

Featuring Kunjan Dalal

Having worked in mobile app development for years Kunjan can say one thing for sure: creating a mobile application is hard. Creating a cross-platform mobile application is even harder. Which is why he was interested when Fabulous came out.
