Sagemath with Phone

[NoSyu]

Now I make the WAP Page in Sagemath notebook.

You can write the sage code in textbox. 예제 1 means example 1. So
click the 예제 3, you can see example sage code like this.

Example code is 'plot(sin(x), xmin=-2*pi, xmax=2*pi)'. Click the '실행
(Evaluate)' Button. Then you can see the code and result.

I said it is for phone. So Dr Kim tested this his phone. His phone
is Samsung SPH-W5000.

We can see right result on the phone. We test this on phone that is
sold in Korea such as Samsung Anycall, LG CYON.

And I test this on phone emulator also.

It works fine.

It works good on the phone that is sold in Korea. So we make this
Korean interface. Then Korean people use sagemath on the phone easily.

Now we imporve and expand this. So test it and report bug or bad
things.

A good job! But it have some potential problems (I apologize for
stress tests, which could result in a higher server load):

1. wap_test_01 - a virtual user. Every WAP-call creates a new
worksheet at http://math1.skku.ac.kr/home/wap_test_01, and intensive
use lead to wasting of wap_test_01 notebook. Possible solution - to do
"groundhog day" (proposed by Dan Drake) or remove "old" worksheets.

2. Access denied to any data, associated with cell. For example,
worksheet http://math1.skku.ac.kr/home/pub/191/ has a link
http://math1.skku.ac.kr/home/wap_test_01/98/cells/0/full_output.txt,
which can't be retrieved any way.

3. Bugs (features): a) string constants must be only 'string', not
"string"; b) single '/' must be changed on '//': sh.eval('dir //').

It will be very nice if output would be typesetted with jsmath or
shown as sage->latex->dvi->png.

Sincerely, Sergey

[NoSyu]

Thanks to reply it.

I surprised that sage is accepted sh operation.

Maybe it should be banned.


1.

Yes.

wap_test_01 is virtual user for wap_html page.

and one process by one worksheet.

Maybe I make the delete function automatically when sage notebook is
lauched or whenever.

groundhog day? I don't know about it. I should be search or ask to Dan
Drake. Thanks to give the good information.



2. Oh...

In fact, the reason why it publish the worksheet is that if it do not,
picture is can be seen to anonymous.

But txt file is not...

I search or make another way to solve this problem.



3. String constants?

I don't understand it.

Sorry.



We consider the jsmath, but phone web browser in Korean phone service
can't work javascript code.

So we remove it.

But latex is good.

I make and test it later.



Thanks to test and report it.

And Thanks to send the email with gettext code.

I test it and make the Korean po file.


Have a nice weekend.!

txt file - a truncated output. Sage notebook use special commentary
tag <!--notruncate-->, so you must simply insert it before every
command, using http://math1.skku.ac.kr/wap_html:

html('<!--notruncate-->')
command_produced_big_output

It was my error, don't think about it.

You can do LaTeX support in some minutes, because you already can sent
images to users:

1) do template:

html('<!--notruncate-->')
command_produced_some_output
latex(_)

2) latex output send to mimetex (http://www.forkosh.dreamhost.com/
mimetex.html) - a fast and simple tool, produced fine graphical
output;

3) deliver it as any another image.
