Sometimes in F# it is useful to use LINQ extension methods such as .Take(n), .Skip(n) and .Count(). However, in F# some LINQ extension methods such as .Where(...) and .Select(...) require a type annotation on the lambda variable. This is one of the relatively rare cases where F# code requires a type annotation where other languages do not, and is due to differences in the process of type inference and method overload resolution. Luckily, there is a simple useful workaround. First add the library code below[...]

Microsoft Research Cambridge have a 5 month contract position available to explore appliications of F# Information Rich Programming to some or all of open government data scientific data standards cloud programming protocols such as Protobuf web programming patterns such as REST cross-language interoperability as well as extensions to the F# query and/or type provider mechanisms. Candidates should ideally be experienced F# programmers with demonstrated capabilities in implementing type providers for F#. [...]

Tech Mesh - The Alternative Programming Conference is designed to support and promote useful non-mainstream technologies in the software industry and dedicated to users and inventors of various languages and technologies. By offering a networking platform to IT architects, software developers and project managers it brings together different programming worlds and creates opportunities to exchange experiences and knowledge, necessary to pick the ”the right tool for the job”.

As of today I’ve completed my fifth course at Coursea, all but one being directly related to Machine Learning. The fact that you can now take classes given by many of most well known researchers in their field who work at some of the most lauded institutions for no cost at all is a testament [...]

I have been obsessing about the following idea lately – what if I could run a FSI session from within Excel? The motivation behind this is double. First, one thing Excel is good at is creating and formatting charts. If I could use F# for data manipulation, and Excel for data visualization, I would be a happy camper. Then, I think F# via FSI could provide an interesting alternative for Excel automation. I’d much rather leverage existing .NET libraries to, say, grab data from the internet, than write some VB[...]
