One should say very clearly that black on white—#000000 on #ffffff—is a poor choice except on poor displays or in poor viewing conditions. Much better is a lightly greyish or ever-so-slightly yellowish/brownish background with a less than fully saturated black for the text. Printers have known this all along. Edit—author says so in his article. FWIW I might add that while my terminal emulator and my text editor both use light on dark color schemes, the way to make that work is to reduce contrasts. The most horribly eye straining web sites use incredibly harsh contrasts. I can work for many hours in both apps before getting anywhere near the condition that many 'dark mode' web sites can cause in a minute or so.
