POSTAL DEVILS EATING CDS?
develop is the most exciting piece of regular mail I get after Japanese animation laserdiscs. I joyfully
received Issue 11 but unfortunately the wolverines in the Postal Service dined on some of the plastic
and no CD was to be found! Help!
-- Jim Perry
Would you consider mailing develop in a nonperforated plastic wrapping? The perforation was two-
thirds torn when I received it.
-- Eva Schlesinger
I really enjoy develop , but I have to say that I've enjoyed it less recently.
Some time ago the CDs came in a small envelope well protected inside the magazine, and everything
was fine. Now, develop is shipped with the CD in its own holder, which would seem to be a fabulous
idea except that you were blind-sided by the U.S. Post Office.
Every month since the CD got its own holder, the Post Office has mangled my plastic bag, CD
holder, and magazine. Today my develop issue 11 arrived sans CD. I called the subscription office
(1-800-545-9364) and they promise to send me another within four weeks.(!?) Growl.
-- Bob Cent
Most of the mail I get is, unfortunately, on this subject. Our Production Manager, Hartley Lesser, really has
been working on it. Even with Issue 11, we took a small step toward solving the problem: since many people
thought someone was breaking open the package and stealing the CD, we inserted a thick sheet of paper over
the CD so that it wouldn't be visible. But complaints of torn packaging still came in, so clearly the packaging
just wasn't sturdy enough. The packaging around Issue 12 and its CD should be about twice as thick as before
and have no perforation. If that doesn't work we'll try something else.
Issue 7 was the last one to list the 800 number you used to contact the subscription office (though it stubbornly
has still shown up on our renewal notice). The correct number is 1-800-877-5548. The person you spoke to
normally doesn't handle calls regarding develop and didn't know that replacement CDs should be mailed
within a day or two of notification of the problem. Sorry for the mixup. We hope you'll never need that service
again!

SCREENWRITING CAVEAT
Your Issue 11 column on drawing to the screen was really useful to me. I had an animation program
that wrote directly to the screen and it worked fine. But when I upgraded to a new accelerator card
my program kept crashing. I spent months trying to figure out the problem. But your article fixed it
straight away. All I needed was the SwapMMUMode calls. I don't know why the previous card
didn't require them, but my program works fine now.
-- Tony Cooper
Thanks for your interest in the column. We're glad it was helpful to you.
One thing we want to be sure to mention is that writing directly to the screen will break for sure on future
Macintosh systems based on RISC technology. And we again want to stress that the only applications that
should even consider writing directly to the screen are games and other animation programs.

USER-FRIENDLY RENEWING
Recently I received a couple of renewal notices for develop in the mail. In trying to decipher these
notices, I realized that user friendliness is something we should all be aiming for not just in thesoftware we write, but in everything we do. It's interesting how working with the Macintosh makes
one aware of human interface issues in everyday life.
Anyway, I think there are a few ways in which the develop renewal notices could be made more user
friendly:
- Leave a bigger space for writing the credit card number.
- Clearly indicate on the renewal notice the date my subscription expires.
- Is there any reason why the renewal notices are printed in red ink?
--Tim Hammett
We're in the process of making the changes you suggested to the develop renewal notice.
- We'll leave a bigger space for writing the credit card number.
- The notice will indicate when the subscription expires. You can also find this out at any time from your
mailing label: the number that appears on a line by itself at the top of the label indicates the last issue you'll
receive unless you renew.
- The reason for the red ink is so that this little piece of paper doesn't get lost on your desk. But you've
inspired us to change it to a more readable, deeper red.
We're also correcting the 800 phone number on the notice, to 1-800-877-5548.
Thanks for your letter. Without it, I would have assumed that the renewal notice (which isn't really in my
domain) was in great shape. I appreciate the enlightenment.

REUSED CDS: IS IT ART?
In Issue 10 of develop , Bruce Radford stated that he wasn't sure what to do with his old CDs. He felt
that he should recycle them, but he wasn't sure how. Well, I have a suggestion.
Many people forget that reusing something is often even better than straight recycling. My school
would have many uses for old issues of the develop CD. I know a few friends who would love copies,
no matter how old; I could use them in a programming class; and other students could cut them up
to make jewelry for school fundraisers. I also have many uses for old 256K SIMMs, which seem to
be becoming about as useful as pennies now.
So go ahead and send the stuff that you think no one needs to me, or to a school near you.

Thanks for the idea. Day care centers and children's museums have also been mentioned as possible destinations
for old CDs. We suggest that before giving away CDs for for art projects, developers put a deep scratch
through the data side of the CD if it contains any confidential or licensed data.
For some wild and crazy ideas on this from Apple's Developer Support Center, see the
Q & A on page 126.

DEVELOP INTERNET ADDRESS
I'm on the Internet and develop contains only AppleLink addresses. I'm guessing that
crose@applelink.apple.com is your Internet address. develop really should have an Internet address for
academic developers to send e-mail to.
-- Eric Kofoid
Adding "applelink.apple.com" to any AppleLink address converts it to an Internet address. The Internet
addresses for me and develop's Technical Editor Dave Johnson are listed on the last page of every issue.
-- Caroline Rose
BACK ISSUES CONUNDRUM
I noticed that your back issues are listed at $13 in develop and at $10 in the APDA catalog.
Why the discrepancy? Who should I order the back issues from?
-- Michael Tackie
P.S. Great magazine. Very technical. I don't understand everything, but that's good; it forces me to
become a better programmer.
You pay a $3 shipping charge when you order from APDA, so it adds up to $13 in the end.
-- Caroline Rose
P.S. Thanks!
CORRECTION TO APPLE EVENTS ARTICLE IN ISSUE 10
The "Apple Event Objects and You" article in develop Issue 10 contains two errors in the printed sample
code. The first problem is that five lines were omitted from the end of GetWindowIndex. The code at the top
of page 25 should be changed from
return noErr;
}
to
if ((rawIndex> numWindows)||(rawIndex<= 0)) {
*index = 0;
return errAENoSuchObject;
} else
*index = rawIndex;
return noErr
}
The second bug is in the routine WriteRectToken (page 30). The following call
BlockMove(*thisRectDesc.dataHandle,
&tokenPtr->theRect,sizeof(Rect));
should be changed to
BlockMove(*thisRectDesc.dataHandle,
(Ptr)tokenPtr->theRect,sizeof(Rect));
Since theRect is actually a pointer to a rectangle (see the declaration at the top of page 29), the first version
would have destroyed the pointer and four bytes of the following long integer.
Thanks to Doug McKenna, the author of Resorcerer, for pointing out these problems.
WHY DON'T YOU WRITE MORE OFTEN?We welcome timely letters to the editors, especially from readers reacting to articles that we publish in develop . Letters
should be addressed to Caroline Rose (or, if technical develop -related questions, to Dave Johnson) at Apple Computer,
Inc., 20525 Mariani Avenue, M/S 75-2B, Cupertino, CA 95014 (AppleLink CROSE or JOHNSON.DK). All letters shouldinclude your name and company name as well as your address and phone number. Letters may be excerpted or edited for
clarity (or to make them say what we wish they did). *
