Refreshing Media doubt
Congratulations on your fine magazine. I find MacTutor to be a valuable
resource. I read your editorial in the June 1992 issue on the LA riots, and you are the
first person in the media to cast any doubt on the “politically correct” opinion. As it
happens, I attneded a course last year given by a policeman who also works as an expert
witness in self defense cases. He predicted that the LA police officers would be acquited
because of evidence which was not part of that juicy tape. When the riots broke out I
could not help but think that the media had inflamed public opinion to the extent that
they were culpable in the crimes committed.
I realize that MacTutor is not an appropriate forum for such issues, but when
you’re the editor and something has you really angry, that’s what the printing presses
are for. [Obviously, I agree. Thanks for the support. -Ed.]

Comments on issue #1
Great first issue. There is a definite need for a magazine like MacTutor that
hasn't been addressed with the other two 'fluff' magazines. I cancelled my subscription
to the other magazines when the pages of advertisment was greater than the pages of
articles.
Here's what I would like to see in MacTutor v: 2.0. A section for "beginners". I
don't believe I've ever seen a MacTutor article on "How to set up your data structures
for easy window scrolling", "Proper use of the 'other' numeric data types", or "So you
bought (an application generator program like AppMaker) - now what?". Figuring out
how to scroll a window can be an exersize in frustration for the beginner. An article or
two on tips and hints for scrolling would be of value to the readers. In Pascal, there
are Comp, Extended, Extended96 numeric types. An article on when to use these other
numeric types would be helpful as well as an article on what to expect when using
programs like AppMaker. It does a lot for "me," now what do I have to do and where are
the pitfalls. These are areas that would be helpfull to the beginner and intermediate
programmer.
For the more advanced, how about articles on mixing SANE and '881 extended
data types in the same application. Or how about an article on installing your own
Gestalt selectors. [Authors: are you listening? - Ed.]
I like the idea of the "Tips & Hints", but the first one of forcing the Finder to quit
to re-build your desktop, well Some how pulling the rug from under the Finder is an
easy way to say goodbye to the disk's directory. [Actually, it doesn’t cause a problem. -
Ed.]
Looking forward to the next issue

Name Sharing cdev
In your "Tips and Tidbits" question from Dave Mark, he spoke about wanting a
cdev that would allow you to change the name of the machine. There is a cdev in System
7, and it's called "Sharing Setup". Encouraging developers to hack with system
resources directly may be fun, but it doesn't help maintain compatability, it polite to
the user to modify them underneath.
[As Lincoln Lydick from Littleton, Colorado found out, getting to these resources
is easy, but making them behave the way you want to is tough. Hats off to Lincoln for
the fatest turnaround on a tidbit request we’ve ever seen. But as we all know now,
System 7’s sharing setup does a good job already.]

More Pascal Code
As a budding Macintosh programmer, I'm glad to see that MacTutor is back in
print. But there is one thing that I would like to see included in future issues: MORE
PASCAL CODE!
I realize that C is the language of choice for most professionals, but as a
beginning programmer I decided to stick with the language used a standard throughout
the Inside Macintosh books. Also, I've been told it is better to learn the structured
discipline of Pascal before learning C.
As it was, there wasn't anything in the April/May issue that was helpful for me.
How about some more general purpose programs in the Pascal Workshop department. I
don't have SuperPaint, or give a flip about airbrush masks. Please print some source
code I can use. [Look beyond the airbrushes at code segments and the general concept of
plug-ins. Isn’t that interesting to you? - Ed.]
One more thing: I have "The Macintosh Pascal Programming Primer, vol.1" by
Mark and Reed, and vol.2 is mentioned throughout the book; in fact, I think I've even
seen it. How come it isn't mentioned in the bio on Dave Mark?
So I'm glad your back in print, I just hope future issues will help me out a little
more.

On the spine
I was just reading some back issues of mactutor and as a result I have a
suggestion. It's nice to have the theme or main article for the issue on the spine so you
can quickly locate topics. I realize that not all articles could be displayed but even one
would be nice. For example I can glance over at my back issues and tell that volume 5 no
7 covers network printing. [Your suggestion was heard and implemented. Look on the
spine of this issue. -Ed.]

More Good Programming Books
Dave Mark's column in the April/May '92 issue was great with one glaring
exception. I find it hard to accept his recommendation that your readers "...wait until
June..." to be able to buy a book that features System 7 C sources (his book, naturally);
e specially since a major publisher is already shipping a System 7 C-based
programming book and has been shipping it for quite some time.
"Programming for System 7" has been available since last November and it
should be in all of the major bookstores. It's published by Addison-Wesley as part of
their "Macintosh Inside Out" series and the entire book is focused on System 7 (not just
part of the book). If local bookstores don't stock it, APDA does (1-800-282-2732).
"Programming for System 7" is the first "code-level" System 7 book based on C
and is the only currently available alternative to Inside Mac, volume VI.

Get Rid of Tools
I've been a reader (on and off) for the past 5 years. I used to get magazines that
had soft covers. And to boot, I have the first three volumes of MacTutor.
I'm very happy you're back. My withdrawal symtoms were severe. I would like
to see CODE, CODE, CODE. And explanations thereof. I find that if a magazine has more
that 10% of "Tools of the trade" stuff it hits the garbage. God forbid there should be
user oriented stuff in the "Tools of the trade" column (or anywhere else!). I think the
old format is fine. Forth is not used very much by me or any mac programmers I know.
So take that as a NO vote on Forth. I don't know anybody who programs in fortran (or
will admit to it)...Another NO.
I find that this magazine is a perfect vehicle for purely programmer oriented
stuff like in Dr. Dobbs. How to write a compiler for the Mac (oh WOW!) or how does
the MPW linker differ from the THINK one. How to write something like RTPatch for
the Mac. Why is there nothing like that on the Mac (hint... the Data/Resource forks).
I hope my rambling gives you some insights into a nutty Mac programmer's
wishes.. Keep up the good work.
[I hear you. The tools of the trade are a must for many people and will remain.
Articles provide information to people, but a product review that addresses a product
that does what you want can be FAR more useful to a person. The bit on Fortran and
Forth addresses many of the institutional, educational and scientific readers.
Remember, that MacTutor is a lot of things to a lot of people. Tell me what you
want, instead of what you don't want. That way, I can try to get what YOU want in the
magazine. The things you don't want to read, you don't have to, but usually even those
articles that don’t seem appropriate on the surface, have useful information inside for
you. Give even the languages you don’t use a chance, the algorithm is what is important.

Table of Contents Cover
Bring back the table-of-contents front cover. That was a cover that said, “This
is a programming journal. We mean business. Casually interested Mac users and PC
programmers need not apply.” [I too remember those covers way back when. There
are two problems with them. First, is that they don’t sell as many newsstand copies of
the magazine. Second, is that the cover of the magazine is produced at a different time
from the rest of the magazine which limits our flexibility. - Ed.]
Lose the vertically split pages (e.g.: the MacForth/LS FORTRAN articles.)
[Already done. In the future, if we did another split page, it would only be the first
page of the article. - Ed.]
