Last but not least, are you, personally, a Maplesoft's customer?
Or your Maple (if you use it) is paid by Nokia, not out of your
own pocket?

Is your experience in programming and prime numbers a substitute
for quality assurance items?

If your goal was to shock my QA soul with your amazing software
testing achievements, please feel free to show them.

TL> "Why not report the bugs to Maplesoft support?"


Yes, right you are!

Generally, this is a NECESSARY condition to get those DOZENS
THOUSANDS distinct Maple bugs fixed. But over-a-decade-long live
practice of (at least MANY DOZENS) Waterloo Maple/Maplesoft
customers shows with a shocking, dismaying clearness there are
it is NOT SUFFICIENT.

In a single sentence, "Maplesoft support" being a Maplesoft's
service, is a highly inefficient for Maple customers mechanism
directed often to quality assurance problem concealment, and
persuasion of the customers that Maple is far much better than
it is actually (read: it worthwhile to be acquired).

Not so infrequently, Maplesoft support provides the customers
(me, too, several times already, despite I do not write to the
Maplesoft too often) with formal answers reading which one thinks
involuntarily that the answering person simply either did not
read your letter at all, or was too busy (or unable?) to
understand it...

Maybe reading this message to the end would help you to see
why reporting the Maple bugs publicly is ESSENTIAL.

Some users are getting very frustrated with the lack of public

I believe that if nothing is done to address this issue, then
Maple will quickly become a system which is only useful for
teaching calculus and other low-level courses. It will be useless
for research.

In a nutshell, one of the final goals is making all the Maple's
consumers' life easier via making Maple faster, more stable and
so to say, more intelligent.

So, one of the goals is to HELP Maplesoft to improve Maple if
the company wants this, and to FORCE Maplesoft to improve Maple
if the company does not wants this. The maximal public Maple bugs
exposure is a tool of our users' influence on the wistful case.

Guess what, I just tried both of your test cases in Maple 10.04

So what? This does not contradict what Vladimir writes.


But he very conveniently left out the latest version and given that
it is a simple download for those who have licensed Maple 10,
I doubt that many people still use 10.0.0 which is the version he
compared to.

And how many users do you think work with 10.04?
And how many with older versions?

I guess that most people are either using Maple 9, 9.5 or 10.



So, this makes me wonder how many more of your "bugs" are really there.

Don't wonder, find it out! The case I could check works exactly
as Vladimir writes:

Most of the "bugs" he continues to post are for cases I don't care
about at all. Hell, even this one I don't care about, I just happened
to test it.
I just wondered because if he neglected 10.04 in this case, how many
other cases does he ignore particular versions.


I wish Google Groups had a killfile.

Why? Why always kill the person who brings the bad news?


BTW, a killfile is a file that usenet reader software uses to
automatically hide posts by particular people so you don't have
to read their comments.

I would like a killfile because of his inflammatory comments he
likes to make. Witness the title of this post which has changed
from the original which was an honest query about a bug someone
found. I don't doubt that Maple has bugs, I've run across a few
myself, that doesn't make them liars. Why not report the bugs to
Maplesoft support like the rest of us rather than coming to the
newsgroup and making inflammatory comments. I read this group
to get advice, help, and new insights. None of his posts provide
that for me and they seem to clog up this and many other groups.

Your expected value is not correct, because the side limits for n --> 1
are not equal:
limit to the right = sin(1)
limit to the left = 1.
You shoult "limit" yourself to the real Maple bugs,
or have you discovered all of them?

Thanks for your comment.

You mean this?

product(sin(k/1), k=1..0);
product(sin(k/1), k=1..1);

1
sin(1)

OK. Also, the answer

limit(product(sin(k/n), k=1..n), n = 1)

would not be too bad, as I already pointed out. But in fact,
in the given case, I do not feel it's really material what
is the expected answer.

The main point is that Maple 8 - Maple 9 - Maple 10 return
a piece of total bunk, exp(sum(ln(sin(k)),k = 1 .. n)) .

M> You shoult "limit" yourself to the real Maple bugs,

Take it or leave it, but right away I am the # 1 world's
QA engineer in this field.

http://groups.google.com/group/sci.math.symbolic/msg/5123d38af7c24ad3

This said, please realize that the showed publicly stuff
is a far cry from my last word in the field.

M> You shoult "limit" yourself to the real Maple bugs,

Jocularly speaking, with the course of time, I decided that
I was too lazy to discover Maple bugs.

This is why I invented the VM machine we keep implementing.

But of course, this explanation shows only one of the
aspects of why I decided to do it; now it's still ahead
of time to discuss this.

M> or have you discovered all of them?

The VM machine has already discovered far many more
distinct Maple bugs than we the human being have done
and posted to public domain, altogether.

However, the shower of distinct Maple bug manifestations
is not getting weaker...

One fine day, not tomorrow, we will come back to this
point.

Or perhaps use my CAS below which is bug free - always computing the

Here is the source code - feel free to copy and redistribute if you wish.

Being a testing amateur, we

"were totally blown away by Maplesoft's Maple 10

because we have not enough time or care to read
the postings by the Cyber Tester's engineers, and
thus we are not able to realize the simple truth
that there are many dozens of thousands distinct
Maple bugs including but not limited to many 1000s
of (multiple) regression bugs.

Really, why care, we are a writer, not a reader.

COMPARE: Mathematica 5.2

DSolve[{D[y[z],{z,2}]==y[z]/z, y[0]==0, y'[0]==1}, y[z],z]

{{y[z] -> Sqrt[z]*BesselI[1, 2*Sqrt[z]]}}

MuPAD 4.0

solve(ode({diff(y(z),z$2)= y(z)/z, y(0)=0, y'(0)=1},y(z)));

{z^(1/2)*besselI(1, 2*z^(1/2))}
