Can't still find any decent tool for sharing objects. Saving and
loading
them in Sage seems to be a simple approach for user but not for an
application to run.
Though this isn't quite what you're looking for, it would be nice to
be able to publish an object just like one publishes a worksheet on
a public server. It would then give a url where the .sobj can be
downloaded (by anyone, so to send you an object I would write in a
notebook cell)
publish(a)
http://sagenb.org/pub/unique_name.sobj
which would return a url that's good as long as the server is live,
and you could send it to someone (e.g. via email or chat) and they
could load it with load(http://sagenb.org/pub/unique_name.sobj;).
From the command line it could perhaps just save it as a file and
return the filename.
You can already do this. In a worksheet, just do
save(a,'a.sobj')
then publish the worksheet that contains a, then there will be a link
to the sobj.
E.g., I just published http://sagenb.org/home/pub/505/ which contains
such a link:
http://sagenb.org/home/pub/505/cells/2/a.sobj
Now anybody can do:

Ah, yes, you can. I still think it might be handy to be able to just
publish objects detached from worksheets though. Taken one step
Yes, this could be useful indeed.
further, being able to push them too to a public place (though
this opens a whole can of authentication/security issues).
Well, this is very easy in gLite.
One would have to just save an object and copy it to the public space
in Grid storage information system.
I might make this possible for SAGE some time.
There is also an idea to use RSS feeds for spreading information about
published objects and notebooks. (see my post Sage RSS reader in
firefox and .xml .rss in SAGE)

[sage-support] Re: SageWorld
May be I reinventing bicycle ?
Could anyone comment whether something familiar has been already known ?
I want to play mathematics with my kid and colleagues with the help of Sage.
Is it a bad idea ?
Serge A. Salamanka
Serge Salamanka пишет:
This is very simple and effective but not for the task I'm heading for.
It might be better to start from the idea itself.
SageWorld is mathematical world where everyone could create mathematical
objects and operate them to win a certain battle.
For example, the world in 3D space with physical laws and its constants:
SageWarrior creates there an object according to the rules existing in
this SageWorld. SageWarrior owns this object until he is available to
control its behavior. The task and challenge is to occupy more space or
to control more objects.
In a way it is just for the game )))
But perhaps would be practically useful.
So I need tools to make one separate session for SageWorld with its own
behavior and the tools to connect to this session by users and
manipulate objects.
Thus the SageWar begins. :)

Each user runs IPython shell when working with Sage (also from notebook).
There is a need to make the user objects accessible to others (say, like
to work in the same session).
The best would be even to use ACLs for controlling access to objects
(say, another user cannot modify object but only read and use it).
Could you please point me to the right direction.
I suppose I should look for this somewhere in python functionality ?

[sage-support] Re: SageWorld
Thank you, Mike Let's say, I run a Sage process on some python code which creates a space and sets variables and constants, starts time and log, loads objects and does manipulations with them, writes back the state of the objects. From user side I have to: - create object, - share it somehow with Sage, - have access to manipulate it (others should not be able to do that), - get the state of my object and other objects in the space, - decide what to do with my object: transform it or move it, either smth else, - share these changes with Sage. Ex., I follow picture of 2D graph where I have a circle to be my object in sageworld. Someone else joins in and draws a square somewhere close. Sage code checks that objects do not intercept. I need to swallow up that square. I write code for necessary transformations taking into account restrictions and all the rules of the sageworld and send it to a sage session. On the other end, the user which has a square looks at his 2d graph and sees that circle has begun transforming in a strange way. The task of that user is to avoid swallowing of his square by the circle. He makes the necessary precautions and sends the code to sageworld. This is a simple thing what I want to do. Sorry, if I described it very silly. But just to illustrate that writing a client may be is not the way to accomplish the task ... ??? I don't know. But thank you for the idea Serge Mike Hansen пишет: On Wed, Apr 29, 2009 at 3:00 PM, Serge Salamanka salsa-...@tut.by wrote: Is it a good idea to share objects between python processes with the help of any database ?
