Historical errata for Confident Ruby

“An IRC Bot object, as defined by the Cinch [page 0] IRC Framework” contains what looks like a bad link or reference. Or my copy of the PDF is missing page 0.

Most of the PDFs I get from PragProg have a “report erratum” link at the bottom of each page, but I don’t see that link here. Is it AWOL?

The PDF pages are numbered sequentially from 1 and do not match the page numbers printed on each page. For example, page “i” is 1, page “xiv” is 14, and page “1” is 15.

The code example (`filter_through_pipe`) at the top of the page is badly indented.

The word “insuring” should be “ensuring”.

Not sure if this is an epub encoding issue or a bug in Apple iBooks, 2 sections of code are not being shown properly. I can only get 1 of them to show at a time by resizing the iBooks window while all other code segments displayed fine so far.

The code segments affected are in and right after the paragraphs below:

“Unfortunately, the calling convention for TrafficLight methods taking a State has only gotten worse:

light = TrafficLight.new
light.change_to(TrafficLight::Caution.new)
light.signal

We decide to improve this with a conversion function.”

References to things in the PDF often refer to Page 0. A search for [page 0] in the PDF yields 18 results.

ibook formatting may be broken. Page 26 is empty instead of showing some code. On page 27 there’s a scrollbar box with no content, and the text refers to code that has either been shown out of sequence or is missing.
