In April, at the Xamarin Evolve conference, Xamarin announced support for the F# language as part of the Xamarin tools for iOS and Android app programming. Microsoft were Platinum sponsors of Xamarin Evolve.   This Thursday at the F#unctional Londoners' Meetup we have Neil Danson on F# on iPad and iPhone in Xamarin Studio. Neil Danson will take you through developing apps for iPad and iPhone with F# using Xamarin Studio. See also http://fsharp.org/use/ios/ Bio: Neil Danson is a Senior Software Developer an[...]

I got interested in the following question lately: given a data set of examples with some continuous-valued features and discrete classes, what’s a good way to reduce the continuous features into a set of discrete values? What makes this question interesting? One very specific reason is that some machine learning algorithms, like Decision Trees, require discrete features. As a result, potentially informative data has to be discarded. For example, consider the Titanic dataset: we know the age of passengers [...]

Last week, we had our first Coding Dojo at SFSharp.org, the San Francisco F# group – and it was great! A few people in the group had mentioned that at that point they were already convinced F# was a great language, and that what they wanted was help getting started writing actual code, so I figured this would be a good format to try out. What I wanted was something fun, something cool people could realistically achieve under 2 hours. I settled for one of the Kaggle introduction problems, a classic of Machi[...]

As part of the app I developed for AngelHack I wanted to display some data in a classic grid style. Android offers a GridView as part of the basic SDK, however if you look at all the samples they only show how to use it as a grid of images, essentially they only demonstrate usages where all columns show the same thing, usually columns of photographs. It’s not too tricky to use the GridView as classic “data grid” but it did require a wee bit of thinking, so I thought I put together a quick example to show h[...]
