R Package for @racently

I recently wrote about an API for @racently. The next logical step was to build a package which wraps the API so that the data can easily be pulled into R. The package is available here. It is still very much a work in progress: the API only exposes two endpoints, but both of them are wrapped in the package. Installation Install...

I did a remote install of Ubuntu Server today. This was somewhat novel because it’s the first time that I have not had physical access to the machine I was installing on. The server install went very smoothly indeed. The next tasks were to install RStudio Server and Shiny Server. The installation process for each of these is well documented...
