“ Dijkstra always believed it a scientist’s duty to maintain a lively correspondence with his scientific colleagues. To a greater extent than most of us, he put that conviction into practice. For over four decades, he mailed copies of his consecutively numbered technical notes, trip reports, insightful observations, and pungent commentaries, known collectively as “EWDs”, to several dozen recipients in academia and industry. Thanks to the ubiquity of the photocopier and the wide interest in Dijkstra’s writings, the informal circulation of many of the EWDs eventually reached into the thousands. “

The prose strikes one in the vein of a 20th century existential writer.

I am reminded of Salieri's reaction to Mozart's manuscripts in the movie Amadeus.
Dijkstra’s I/O apparatus corresponds to communication mechanisms for tape reading.
