As part of FsShelter development I had to implement the multilang serilizers for Storm, originally building against then current Storm 0.10.0. I’ve started with Thrift, thinking that since its already a part of Storm runtime it would make the adoption easier compared to protobuf and given similar  characteristics the downgrade in performance would not be […]

Thanks to docker, trying something out w/o having to figure out all the dependencies and pollute your system has become really easy. This is how I started with Storm and this is the way we now help others to try FsShelter as well – fsshelter-samples container. The container includes an installation of Storm, Mono, F# and a pre-built […]

About a year ago Prolucid adopted Apache Storm as our platform of choice for event stream processing and F# as our language of choice for all of our “cloud” development. FsStorm was an essential part that let us iterate, scale and deliver quickly, but even from the earliest days it was obvious that the developer experience could be improved. […]

Literally. Well almost. 2 meaningful lines + some boilerplate. This has got to be easier than even Python! Using EmguCV, a wrapper around OpenCV and F# Interactive:

One of those things that I keep searching on the internet, for examples and Howto’s is, how do you hide stuff in Fsharp?Hiding stuff can be very useful. When you create a library, or a DSL, or perhaps a framework, you want to provide a good user-experience by hiding implementation details.  At the same time, you don’t want your code to add a magnitude of complexity, to fulfil this requirement. Fsharp is perfect for that, and the following may help.Note that I will only handle cases whic [...]
