Writing about practical F# coding and programming language research

Happy New Year 2016 around the World

Just like last year and the year before, I wanted to participate in the #FsAdvent event, where someone writes a blog post about something they did with F# during December. Thanks to Sergey Tihon for the organization of the English version and the Japanese F# community for coming up with the idea a few years ago!

As my blog post ended up on 31 December, I wanted to do something that would fit well with the theme of ending of 2015 and starting of the new year 2016 and so I decided to write a little interactive web site that tracks the "Happy New Year" tweets live across the globe. This is partly inspired by Happy New Year Tweets from Twitter in 2014, but rather than analyzing data in retrospect, you can watch 2016 come live!

Philosophy of science books every computer scientist should read

Thursday, 10 December 2015, 12:42 PM

When I tell my fellow computer scientists or software developers that I'm interested in philosophy of science, they first look a bit confused, then we have a really interesting discussion about it and then they ask me for some interesting books they could read about it. So, I thought I should turn my answer into a blog post!

F# + ML |> MVP Summit Talks

Wednesday, 18 November 2015, 2:03 AM

I was fortunate enough to make it to the Microsoft MVP summit this year. I didn't learn anything secret (and even if I did, I wouldn't tell you!) but one thing Idid learn is that there is a lot of interest in data science and machine learning. What was less expected and more exciting was that there was also a lot of interest in F#!

The Gamma: Simple code behind interactive articles

Monday, 28 September 2015, 5:07 PM

Computer programming may not be the new literacy, but it is finding its way intomany areas of modern society. In particular, data journalism turns traditional news reports from a mix of text and images into something that is much closer to a computer program.By treating articles as programs, we can make data journalism more transparent, reproducible and interactive. This is what I've been working on recently, so check out the prototype!

Creating web sites with Suave: How to contribute to F# Snippets

Tuesday, 15 September 2015, 11:26 PM

The core of many web sites and web APIs is very simple. Given an HTTP request, produce a HTTP response. Sounds pretty simple, so why are there so many evil frameworks that make simple web programming difficult? In this blog post, I'll write about Suave -a nice composable library for web programming with F#. The blog post also shows a few interesting samples from the new version of F# Snippets and you are welcome to contribute!

Welcome!

I'm an open-source developer and computer scientist who enjoys combining theory and practice. On the practical side, I write about F#, run trainings and provide consulting via fsharpWorks. On the theory side, I work on various programming language topics.

Trainings and consulting

I'm a frequent speaker at F# and .NET events, founding member of the F# Foundation author of C# and F# book and a StackOverflow fanatic. I have been Microsoft C# MVP since 2004 and used F# since early Microsoft Research versions.

Have you seen the F# testimonials and are you thinking how your company can also benefit from the safety, correctness, efficiency and faster time-to-market provided by F#?

Research & teaching

I'm interested in a wide range of topics in programming languages, ranging from category theory, comonads, reactive and distributed programming to scientific computing and working with data.

I like working on topics inspired by practical problems. I created a web framework for F# that inspired commercial projects like WebSharper and my experimental F# extensions can be tested live on tryjoinads.org.

When the time permits, I enjoy traveling. The calendar shows a new picture each month. See 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014 and the first photos of 2015.
