Typos for "Touch of Class" draft
How to report a typo
Report it under the appropriate chapter title below. Please include the original section number. The page number is less important as it changes. The best is to copy-paste the relevant text extract and mark the faulty word(s), for example by **...**. It is convenient to show the extract as a display (start lines with spaces) and also, if you wish, to give your name.
For example:
In section 16.1, just after the first figure: Money, Pass, Map, Louvre, Orsay Money, Pass, **Louvre, Map**, Orsay Money, Map, Pass, Louvre, Orsay The second one is wrong. -- Luchin Doblies, 1.12.2008.
(Indeed Luchin Doblies reported this error -- thanks! BM.) The entry should appear in the section for the corresponding chapter (it does now). I am sorry that I will not be able to respond to individual comments, but I will consider all reports and correct the text as needed.
As errors get corrected I strike them out.
Preface etc.

1 The industry of pure ideas
page 5, section 1.1: Computers and related devices are called hardware, indicating that — although they are getting ever lighter — computers are the kind of machine that will hurt your feet. Programs **and all that relates to them** are by contrast called software, a word made up in the 1950s when programs emerged as topic of interest. Comment: one may argue that hardware may relate to hardware (depending on the definition of the relation). As the point is to separate the two concepts, to avoid confusion I would drop **and all that relates to them**. -- MP, 8/2/2009
page 11, picture caption: **(d) GPS navigation system**. For consistency with the iPhone, you may consider adding the Garmin brand, as it looks like it can be easily recognized. -- MP, 8/2/2009
page 13, towards the end: This book emphasizes throughout, along with practices that **make your programs good for the computer** — for example, designing programs so that they will run fast enough —, practices that make them good for human readers. Remark: The way in which the sentence is formulated is not smooth and crystal clear to me. A suggestion could be: This book emphasizes throughout, along with programming practices that put to good use a computer processing power, practices that make programs understandable by human readers. -- MP 8/2/2009
page 14, at the end of box Touch of folk history: This did not deter **the programmer**: “See the holes? They are the software.” Could be: This did not deter one of the programmers: “See the holes? They are the software.”

from Draft 22.02, 23 August 08 19:15 (Santa Barbara)
page 25, section 2.2 OBJECTS AND CALLS/Dissecting the program.
second paragraph.
text:
Then to highlight Line 8 we execute
action:
the code "Line8.highlight" appears on the next page after the end of
the paragraph instead of embedded within the paragraph.
-- Eric Bezault, 12 December 2008
I don't see the problem now so I assume it was fixed earlier

page 31, section 2.3 WHAT IS AN OBJECTS/Objects: a definition. second paragraph. replace: It is also s good by: It is also good -- Eric Bezault, 12 December 2008 I don't see this, so I assume the sentence was removed.
