man-pages-3.23 release; my book progresses

I've uploaded man-pages-3.23 into the release directory (or view the online pages). This release consists entirely of fixes to existing pages.

Meanwhile, progress continues on my book providing a detailed description of Linux and Unix system programming. We now have a title: The Linux Programming Interface. I've also posted the detailed table of contents of chapters 1 to 42. (Full list of chapters here; draft preface here.)
