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.

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 that it is a Garmin 
gps.   
-- 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.”

    I don't see the problem now so I assume it was fixed earlier

s. 84 - (a = b) or (c and ((not d) = e))) ... the last " ) " is one too much or there should be one at the beginning ( " ( " )

s. 97 - Line8.i_th (2)).is_exchange ... " ) " in both examples

s.100 - {3, 7, 911, 13, 15}: ... missing " , " between 9 and 11

s.111 - The first thing we need in our class is a feature representing the line to be built. ... "We call it (the feature) fancy_line... but the feature is " build_a_line " i guess

       We call it fancy_line.

s.121 - line_exists: s /= Void ... line_exists: l /= Void
