F# for Trading
F# is a functional-first, strongly typed programming language that can be used for financial applications like trading. It is open source and runs on .NET. F# allows for domain modeling with types like records and unions, as well as concurrency and computation. F# code is concise and well-suited for expressing business logic, while other languages like C# can handle plumbing code. F# supports Excel and R integration through type providers. It also supports asynchronous workflows, reactive programming with Rx, and distributed computing in the cloud.

Creating Domain Specific Languages in F#
When designing software, we often need to solve numerous instances of the same problem. When designing user-interfaces, we need to describe the layout and interaction. When financial systems, we need to describe a wide range of financial contracts or, for example, recognize different patterns in price change.
Domain Specific Languages (DSLs) give us a way to solve such repeating problems. By designing a composable functional library, we can build an expressive language for describing our problems. Using the flexible F# syntax, we can get code that even non-programmers can understand.
In this practically oriented talk, we'll develop a number of sample DSLs, ending with realistic examples. We'll cover both basic principles of DSL design as well as advanced tricks, such as using the F# 3.0 query syntax.

[4DEV] Bartosz Sokół - Functional developer in object oriented world - how F#...
Object-oriented programming languages have been here for decades, helping millions of developers to deliver (sort of) working software. Still, after many years, we still struggle with things like nulls and exceptions, which make our applications crash in most unexpected ways. So I have taken a challenge - can you use object-oriented language (C#) and write code in a way that those issues are almost gone? I will show how to leverage lessons learned from functional programming to make our applications more bulletproof - and fun to write as well!
"The F# Path to Relaxation", Don Syme
Born in a research lab, raised in the enterprise and now a fully open source, cross-platform language for the Cloud and Web, F# has been a key part of the transformation of programming since the early 2000s. Programming now regularly incorporates both functional and object programming techniques, with compositionality, succinctness, methodology and delivery to match.
I’ll share the story of this journey, and why F# continues to challenge the status quo with the simplicity and combining power of its design elements. I’ll discuss the philosophy underlying the F# language design and how we can look at a variety of seemingly unsolvable technical conflicts in different ways, with the aim making progress and improving society as a whole. Of interest to anyone who cares about programming, open and welcoming to all, come along and join in the fun.
Domain Modeling & Full-Stack Web Development F#
In this case study, we will look at how F# helps tackle the complexity; its type system allows for a clean and intuitive representation of the domain, while keeping us from introducing all sorts of accidental bugs.
In the modern web applications, the issues are many. Developers must be expert of different stacks to be able impact the software. One of those issues is to be able to move from the back-end to the front-end using different languages which involves a lot of context switching and potentially duplicating code such as for validation, or introducing bugs by manually creating objects in a Javascript and sending them back to the server for it to handle. SAFE brings many technologies together into a single type-safe and flexible F# stack. It enables skill reuse since the models can be shared and all you’re required to know is F# for your next web application.
Doc 2011101410543721

FSharp in the enterprise
This document discusses using the F# programming language in an enterprise setting. Some key points:
- F# can speed up development time by 50% or more compared to other languages due to features like type inference, immutability by default, and asynchronous workflows.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
