Thank you very much, great article indeed! The PDF download link to the article at the top of the page requires access approval though, is that the way it is supposed to be?
My bad, I updated it to fix some typos and forgot to open up sharing settings. Should be fixed.
Hmm, even in PDF form it's not possible to read this without humming the Transformers theme and putting in 'Dijkstra's in Disguise' at the relevant places.
