And there's quite aggressive and odd hyphenation. Despite left justified and lots of space everywhere. Rather squeeze the stuff in one line, or start the next one.

But I think LaTeX doesn't get this right by default, too. The microtype package is something that avoids most unnecessary hyphens.

Agreed — I don't think I've ever seen this much hypenation in content that has such a ragged right edge. That is, newspapers have lots of hyphenation, but are justified. This has lots of hyphenation but is not justified, or at least not very well justified.

As an example, half the lines in this paragraph [1] are hyphenated. At the same time, there's a 4-character delta between the shortest and longest lines. It would have been more easily readable (to me, at least) if the entirety of "software" had been bumped to the second line, which would have had the cascading effect of eliminating the need to hyphenate "program" in the following line and "technical" in the line after that.

I'd be curious to know what the author's reason is for laying out text in this way, as I imagine this is based on some of his typographical rules.
