Read the previous article: FSharpArm - part 1 As the previous article was "current-status". Progress brought new insights, and so the following corrections apply:I develop in VS2015 under Windows, so I didn’t need to install Akka.Net on the RPi; installing fsharp for Debian/Ubuntu Linux is enough; The Self-Hosted Websharper template does not work -fully- as was described, see below; Control Panel [...]

I know what's like in the summertime, a bit quiet, so I thought it would be fun to build a Robot Arm, and to control it from a Raspberry Pi using self written F# software.

If you want to write something ambitious like a project planning tool, then such a paste function could be useful.So what does excel put on the clipboard if select a rectangle of cells and copy it? In the Desktop world one would deal with the D [...]

Will the real actor please stand up? This week I acted because of some nice Fsharp news.First I visited a presentation of Riccardo Terrell about Akka.NET this week. Sergey Tihon’s  weekly newsletter mentioned that Mono 4.0.0 was released.So let us combine that. I installed Mono before and now to upgrade in Ubuntu (as root):apt full-upgrade mono-completeThis takes a while. And now to install Akka.NET.
