[Aimmath-developers] is this a bug?

[Gustav W D. <ai...@ma...>]

Should the following be classified as a bug? It looks very strange to me.
Does the same happen on your AiM installations?

Here is an example:

d> This should illustrate the problem.
l> mat
h> mat:=matrix(2,2,[1,2,3,4]);
t> Please enter this matrix: $$@mat@$$
c> MATRIX(2,2,3)
s> [ proc(ans)
        `aim/t`("$$Here is the matrix~~~~~~@mat@$$");
        `aim/t`("$$And here is 5 times that matrix~~~~~~@evalm(5*mat)@$$");
        RETURN(1);
     end proc
     ,mat
   ]
end>




the `aim/t` command will print mat in the first line of the proc, but for
the second line of the procedure it appears to have forgotten what mat is.

I would be very grateful for any suggestions.

[Aimmath-developers] data conflict?

[Gustav W D. <gu...@ma...>]

Here is a question that shows that I don't quite understand how AiM works:
AiM runs several Maple processes in parallel, each one of them reads from
and writes to the same student and quiz data files. So why is there never a
conflict?

[Aimmath-developers] Installation under Windows

[Gustav W D. <ai...@ma...>]

I have committed a file installwin.html in the doc directory with simplified
instructions for installing AiM under Windows. We should add a similar file
for Linux and Mac.

The streamlined installation described in installwin.html does of course not
work with the release 2_1 on SourceForge, but it does work with the
develop_2_1 branch in CVS.

Re: [Aimmath-developers] APPROVAL: multiple AiM installations

[Manolis M. <ma...@ma...>]

I had the impression that we discussed that before and Gustav is using two
AIMs in the same installation of Tomcat (as if using two different
application that Tomcat supports) ...

server.xml only needs to be modified in old versions of tomcat. Ater 3.0.4
one only needs to execute a command like :
server:8080/manager/install?path=/AIM or reload?path=/AIM stop? etc ...
which installs, reloads, stops etc an application (like AIM or any other
webapp)

so I think it's better not to touch server.xml because in some cases (like
mine) there are already things running in Tomcat and special changes in
server.xml that shouldn't be touched. Also this reduces the need to be root
in a server. In reality one could be "tomcat" (I mean the user tomcat) and
use AIM with no problem ... that's how I use it at least...

[Aimmath-developers] streamlined installation

[Gustav W D. <gu...@ma...>]

I have committed the modified Servlet.mpl together with a modified
ManualConfig.dist and Autoconf.mpl. Servlet.mpl no longer overwrites
Tomcat's server.xml.

You should now be able to check out the AiM module into any subdirectory of
the Tomcat/webapps/ directory, put the name of that directory into
ManualConfig.mpl, open Maple and read in AutoConf.mpl, restart Tomcat, and
go.

I am planning to write new installation instructions tomorrow.

Hi Gustav,

To date I haven't used this idea ... I'm not exactly clear on what
you do. I suppose the relevant change for the web.xml in the "AIM"
directory is to globally substitute AIM for ROOT.

And you would do the same in server.xml if you only ever have one of
the development version or the production version going at any one time.

However, I got the feeling that you were saying you could have the two going
simultaneously, in which case server.xml would need to be
changed more substantially ... a different server port? or do
you only need to copy the `<Context path=...' line and give
a different value for path which will appear in the URL?

There are a few things in the configuration process that are unnecessary. I
think when Neil wrote it, he only envisaged that
someone would do it once. Tomcat has a default server.xml which
does need to be overwritten, but as you say once it's been done and
customised further it need not be overwritten again. I would like
Neil to write some documentation about what gets written where with
explanations for administrators ... I'm not sure I completely understand it
yet. I had trouble when doing an upgrade early on such that I
didn't have an admin. password and couldn't use the admin.html page to
add one and found myself installing from scratch. Perhaps the latest changes
to aim/Admin.mpl have fixed the problem I faced.

No objection from me. We can also back up to the earlier version if
necessary. The beauty of CVS.

[Aimmath-developers] APPROVAL: multiple AiM installations

[Gustav W D. <gu...@ma...>]

I find it extremely useful to have several different AiM installations
running on my server. For example I have one in directory "AIM" which is my
production version and another one in "develop" which is the version I test
modifications on. Tomcat has no difficulties with multiple installations, it
even finds them automatically as soon as there is a web.xml file in the
corresponding web-inf directory.

Unfortunately currently the file Servlet.mpl has a section that overwrites
Tomcat's server.xml file. After that AiM will only run in the root directory
and not any other. There is as far as I can see no reason whatsoever to
overwrite Tomcat's server.xml file. Does anyone know a reason for it? So I
will commit a modified Servlet.mpl in which the section overwriting the
server is commented out. At the same time I will also commit an updated
ManualConfig.dist. Unless I hear objections from you of course.

RE: [Aimmath-developers] error when entering administration

I have committed a temporary fix for this bug. You can now enter the zone
administration also when there are no subjects defined yet. Neil will be
able to fix it more nicely later.

[Aimmath-developers] mathdisplay = latex

[Gustav W D. <gu...@ma...>]

I think the option mathdisplay = latex that I proposed, that prevents Alice
from replacing the latex by html, should be included in AiM 3.0. I know that
the possibility of printing quizzes and their solutions in .pdf format has
been requested quite often in the past and it will be very easy to implement
with a little script once the mathdisplay = latex option is in place.

Ken, do you think you could implement the mathdisplay = latex option?

The following message from Neil is relevant:

 I have just added and committed some new files:
 
 OS0Win.mpl
 OSWin.c
 OSWin.dll
 newDate.mpl
 
 Currently, these are isolated: the main AIM code does not 
refer to them
 at all.
 
 The idea is to get the operating system to handle times and 
time zones,
 which AIM currently tries to do for itself, not very 
successfully.  The
 file OSWin.dll is obtained by compiling OSWin.c; the precise 
command used
 (with the Visual Studio C++ compiler) is recorded as a 
comment in OSWin.c.
 
 The file OS0Win.mpl calls define_external() to build a Maple 
reference to
 the functions defined in OSWin.dll.
 
 The file newDate.mpl, which is intended as a replacement for 
Date.mpl, uses
 these references in the FillFromRaw and FillFromCooked 
methods of the Date
 class.
 
 If anyone is feeling keen, you could work on the following:
 (1) Check that this works properly under Windows 98 etc.  
My reading of
     the documentation suggests that it should.
 
 (2) Work out how to do the analogous thing under Linux and 
OSX.
 
 (3) Fit everything together: remove references to time zones 
in AutoConf.mpl
     and Config.mpl, make sure that define_external gets 
called in the right
     place (I don't think it works to just store the result of
 define_external
     in lib/OSWin.m), and so on.
 
 (4) Implement the rest of the functions in OS0DOS.mpl in the 
same way.  The
     time functions are documented at
 
 http://msdn.microsoft.com/library/default.asp?url=/library/en-
us/sysinfo/bas
 e/time.asp?frame=true
     and
 http://msdn.microsoft.com/library/default.asp?url=/library/en-

 _crt_asctime.2c_._wasctime.asp?frame=true
     I presume that the relevant filesystem functions are

Summary: Multi-part questions

Initial Comment:
Multi-part question type should be developed, and the 
following two possible approaches are apparent.

(1) Single AIM question with multi-part entry, formatted 
across the page.  The answer returned as a matrix 
internally. This would be relatively simple, perhaps new 
mark-up tags needed only.  An expanded answer 
prompt which contains {\tt t>, p>, ap>},
returning an $n\times 1$ matrix,  might work.

(2) Mechanisms to access answers to previous 
questions.  This appears more difficult within the current 
object oriented code.

Summary: One question at a time

Initial Comment:
Currently AIM may only be used to set and mark whole 
quizzes.  Clearly there are many other ways computer 
algebra could be used to mark students' responses.

(1) Provide an option for delivering and marking one 
question at a time in a quiz.  This will prevent lots of 
scrolling around large web pages, and reduce server 
load.

(2) Develop mechanisms to jump directly to and from a 
single AIM question from outside applications.

(3) Develop other interfaces. This will allow computer 
algebra marking to be embedded within learning 
materials, not just to be used to deliver set piece 
quizzes. Note, some work on this area already 
completed by Manolis Mavrikis.

[Aimmath-developers] What file(s) are responsible for converting Maple to LaTeX

[Jon B. <jbr...@wo...>]

Hello all,

Now that I have an official release version of Maple 9, I am trying to 
track down some problems that have been present from the first beta of 
9. I believe I have posted before that Maple 9 and AIM are not able to 
translate something like $$@a@$$ to LaTeX for TtH to process. I receive 
a Maple to LaTeX error unless @a@ is a constant like pi or so it 
appears. I even get an error if a=1/2. So I am wondering what files I 
need to look at LaTeX.mpl? Any others?

Another strange behavior is the way my answers are being parsed. If I 
enter something like exp(1) for an answer I get an error saying that 
pxe is forbidden or something similar. Could this be a problem with one 
of my OS X system functions or another problem with Maple 9 and AIM? 
What should I look at for this? SafeParse.mpl? ParsedText.mpl?

As of now I can create courses, add students, add quizzes, add 
questions, etc. So I would tend to think that all of the system 
functions are fine. It just appears to be these two areas where I am 
having problems. Any thoughts would be appreciated.

[Aimmath-developers] problems with zone administration

I have some problems with doing the zone administration in the new AiM. For
example I get the error message:
"There was an untrapped error while processing your command.
string expected for string format"
when I try to show the hidden subjects.

I don't know if only I have the problems because I did something wrong
during installation or whether they are genuine bugs. Please let me know if
you have similar problems.

If you have the same problem and are wondering how you can make any new
subjects visible in spite of the problem: you have to edit the file
WEB-INF\root\DefaultZone.mpl by hand and include the new subject in the
SubjectNames list, as in for example (SubjectNames)=["Presentation",
"Numerical", "nonlinear"]

Re: [Aimmath-developers] Trig package added to develop_2_1

[Jon B. <jbr...@wo...>]

Ah. Thanks. This may be a change to linalg in Maple 9. I believe that 
LineraAlgebra is "replacing" linalg in Maple 9. linalg will still be 
available but they are not recommending its use. I think something 
changed somewhere in the beta process, because I had AIM working on OS 
X with Maple 9.

I checked and neither Make.mpl or AliceServer.mpl contain an explicit 
with(numtheory). However, commenting out pi := Pi: did the trick and 
has things working again. This is something that will have to be looked 
at with the release version of Maple 9. Thanks.

Hi Jon,

In AliceServer.mpl there is the assignation:

pi := Pi:

(line 96 or 97 depending on whether you get it from the distribution
or CVS develop_2_1).

It seems that you have added: 
  with(numtheory):
to probably Make.mpl and AliceServer.mpl (where there are the lines
  with(linalg):
  with(stats):
).

The problem is that numtheory defines a function pi ...

  > ?numtheory,pi
  numtheory[pi] - number of primes less than or equal to

  Calling Sequence
     pi(n)

  Parameters
     n - expression, assumed to be of type integer

  Description
  - The function pi(n) computes the number of prime numbers less 
    than or equal to the given integer n. 

  ...

So if you want to keep that, you should comment out or remove line
96 or 97 of AliceServer.mpl.

  Regards,
  Greg

Greg,

I'm still trying to get everything working under OS X. With the 
impending release of Maple 9, I'm putting things on hold. OS X does not 
have a Maple 7 or 8 top fall back on. As of now I get some strange 
error when I try and login to a site that was working. Can anyone tell 
what is going on here?

#########################
type Exception report

message

description The server encountered an internal error () that prevented 
it from fulfilling this request.

exception
javax.servlet.ServletException: Unexpected output while initializing 
new Aim process:
Error, attempting to assign to `numtheory:-pi` which is protected
##########################

When is AIM trying to assign to numtheory:-pi?

Once things are working I'll be glad to check it out.
