It helps some, but perhaps not quite enough.
In order to help clarify what's going on, I want to express a little
of my own experience, and background. The point of this next bit is
to show that a non newbie might actually be confused by the book,
and to stop that part of the argument altogether.
First, I'm a native English speaker. It is my second language, but I
began speaking it when I was about three, and it is my preferred
Second, I'm experienced in writing software requirements, design, and
also in implementation. I've worked in the OS and driver area dealing
directly with hardware for a number of years. I wrote a small real time
multitasking OS in 1984 or so, and worked with various kernels and
drivers doing hard real time for about 15 years in telecomm, using
various mixtures of C and assembler. I've used UNIX like operating
systems for about the same period of time.
Third, I've written a few pieces of user documentation over the years.
Fourth, I read every single word in the book, some of them more
I had a little trouble understanding just which directory was meant.
If I had a problem, then this is not an issue of newbies. It is not
a problem of not reading the book. It is a problem with the wording
of the book. I believe that I am a part of the target audience,
perhaps a little cut above most in some of my experience.
I also understand the reluctance to take complaints, rather than
contributions. The statement
This isn't clear, rewrite it until I like it.
is not helpful. We used to complain bitterly about users who would
complain that our software wouldn't do what they want, but who also
would not supply verifiable requirements. We had little cartoons
up all over with
Customer: Bring me a rock.
Guy brings back a fist sized rock.
Customer: No, I need a bigger one!
Guy brings one so large, he's carrying it on his back. It's
practically a boulder.
Customer: No, I need a smaller one!
Guy throw up his hands in disgust and walks away.
Complainers are not helpers, and helpers are not complainers.
There is a difference between a complaint and a criticism.
I think this situation is somewhat similar. "Make it clearer"
is not a requirement, and there is no way anyone can know whether
his rewrite is any clearer to someone else. Suggestions for
rewording are an entirely different matter. Like the one
to include "its" in the phraseology.
I think the book is a marvelous thing. I also believe that it
is to some degree a little terse. Terseness has many advantages,
but understandability is not usually one of them. Excessive wordiness
is just as bad, since details get buried in words. So, terseness is
a good thing, generally. Excessive terseness leaves the reader
wondering if he filled in the gaps in the right way.
This is perhaps one of those places, and sometimes an example goes
a long way to helping fill in the gaps. I'm not sure that having
examples for each of the software packages is a good way to handle
that. However, having one example, or at least more words, in the
general description of the kind of "exception to the rule" that
will be encountered, to explain what is meant, might strike the
right compromise between terseness, and maintainability of the
book on the one hand, and wordiness which is hard to maintain
and buries details in the words on the other, and yet improve
I intend to spend some time reading the latest version of the
book and see whether I may be able to make a suggestion along
Oppose globalization and One World Governments like the UN.

I speak only for myself, and I am unanimous in that!
