Modelling Your Queues

Note this is adapted from an original article that goes into much greater detail. Please check it for the nitty-gritty R code in full.

Testing Your Service With Poorly Remote Services

ToxiProxy allows you to create a controllable proxy between your app and a remote service when you want to test network reliability and related effects. It can be downloaded in command line executable form that, when run, will start up a web service on port 8474. You can configure it

Shiny Sentiments

After the Leaflet example I was given another assignment in the Coursera Developing Data Products course. This time the goal was to use Shiny to demonstrate some interactive data analysis and visualisation. I picked two areas I’m fond of, books and sentiment analysis, and combined them to produce the

Fun With R & Leaflet

As part of the Coursera Developing Data Products course I took recently we were asked to produce an example of an interactive R markdown document using Leaflet. So I generated some random cat sightings in and around London, piped them into Leaflet and it produces this sort of map: The

A Game For Griffin

I’ve always wanted to write text adventure games for my children. Griffin in particular is very keen on RPGs. This is their conception of interactive fiction: So I have a few expectations to manage… Anyway I wrote a little game in Inform for him, set in our house. Your
