Functional Programming eXchange 2012 / F#'s Type Providers In Depth

Please RSVP for instructions on how to join the event.

Description

The purpose of most of the real-world applications is to process data that are available in external data sources such as databases and XML files or obtained using a web service or REST API. Accessing such data sources in a typed way is difficult, because the compiler does not understand the structure of the data. In this talk, we look how to use F# 3.0 Type Providers to teach an old compiler new tricks. With type providers, the compiler can understand structure of databases, XML files and web services. This makes it possible to access data from any external data source in a type-safe way with a smooth IDE experience. In this talk, we'll look how to use the standard type providers and we'll also look at implementing a type provider for a custom data source.

Over the last year, I have been working on The Gamma project, which aims to make data-driven visualizations more trustworthy and to enable large number of people to build visualizations backed by data. The Gamma makes it possible to create visualizations [...]

As someone who enjoys being at the intersection of the academic world and the world of industry, I'm very happy to see any attempts at bridging this harmful gap. For this reason, it is great to see that more people are interested in reading academic paper[...]

If you read a about the history of science, you will no doubt be astonished by some of the amazing theories that people used to believe. I recently finished reading The Invention of Science by David Wootton, which documents many of them (and is well worth[...]

As mentioned in an earlier blog post, I've been spending some time at the Alan Turing Institute recently working on The Gamma project. The goal is to make data visualizations on the web more transparent. When you see a visualization online, you should be [...]

There were a lot of rumors recently about the death of facts and even the death of statistics. I believe the core of the problem is that working with facts is quite tedious and the results are often not particularly exciting. Social media made it extremel[...]
