[sage-devel] Question about multivariate power series.
Hi, I was wondering if there is (or is planned) support for natural multivariate power series ring constructions (with say fixed precision for each variable) similar to that of polynomal rings? It would be nice to be able to say something like S = PowerSeriesRing(QQ, 'x,y', [15, 20]) or S.x,y = PowerSeriesRing(QQ, [15, 20]) instead of S1.x = PowerSeriesRing(QQ, 15) S.y = PowerSeriesRing(S1, 20) Thanks, -Jon =) --~--~-~--~~~---~--~~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

Installing sage-vmware-4.1 into VirtualBox worked perfectly first time, exactly according to your instructions. Thanks. There is one thing though that tempers might excitement, which is that the sage-vmware image is an *ancient* unsupported version of Ubuntu from years and years ago. One can't even apt-get update it or install new packages, it is so old. What really needs to happen is to install (a somewhat minimal?) Ubuntu 9.04 server into VirtualBox, then create some similar (or idential) menu system as in sage-vmware-*. It would be better this time though to install a very minimal window system and VirtualBox's tools, so the mouse doesn't get trapped in the virtual machine, which confuses people. Note: Accessing the notebook required that I: 1) Configure VirtualBox to use a 'bridged' network connection 2) First enter 'sage' to get to the command line and type sage: notebook() and enter the admin password (twice). Hit control-C. and exit 3) Now enter 'notebook' to start Sage notebook 4) Start browser with url shown. Regards, Bill Page.

Thanks for the feedback, and apologies for not replying earlier. I have posted an updated draft on http://www.gingerlime.com/20090829__sage_msc_proj_draft.pdf Please see sections 4.1 and 5.4.4 where I documented the sagenb.org setup more clearly.

On Aug 26, 9:45 am, Martin Albrecht m...@informatik.uni-bremen.de wrote: Hi, One thing you repeatedly mention is that sniffing data/credentials may be possible on the public server. I don't think this is ever high risk, as anyone doing sensitive computations shouldn't be using someone else's hardware to do it (SSL encrypted connection or not), especially as it is so easy to run your own personal copy of Sage (locally or somewhere that you trust). Also, by default, there's a big warning on running without https on anything but localhost. With the same argument you could say one shouldn't use webmail or e-mail at all if one thinks e-mail is private. Also, it is not only issues with sensitive computations but SSL would mitigate quite a few threats Yoav pointed out (spoofing, attacks on others, etc.) Encrypting and authenticating worksheets seems beyond the scope of what the Sage notebook should do, there are plenty of 3rd party tools to do this cleanly and it's obvious (I hope) that sharing worksheets is sharing code. The %auto keyword could be bad though. I agree that downloading and mailing worksheets might be beyond the scope of Sage but sharing within Sage certainly isn't. Also, for the download-and-share situation it would be very easy to add some protection because Sage has all the relevant crypto-protocols available anyway. It would send a clear signal that we care about security and would be relatively easy to implement.

[sage-devel] Re: Question about multivariate power series.
You could use the multivariate power series in Maxima. There are 2 versions, maximum total degree and (recursively) maximum individual variable degree. As for design, if you were writing it from scratch, I think the Maple system has a somewhat more flexible implementation. I think Axiom may have a different take on it, if it actually has generators for omitted terms. A few weeks programming can save 30 minutes in the library.

[sage-devel] Factorial syntax
Hi, How about supporting n! as a shortcut for factorial(n)? This syntax is very convenient and makes a huge difference for combinatorial expressions with many factorials. MM (Maple Mathematica) allow this notation, as do many scientific calculators. Although Python doesn't have any other postfix operators, I don't think there's any ambiguity as ! is unused in Python except for the != operator. The worst I can come up with is x!=y, but given that = denotes assignment and not equality, this still only has one possible meaning.

You also mentioned that the setup in this machine would be intentionally less polished (i.e. GNU make is not default, and other things you set up for T2). Would it be possible to evolve the T2 setup towards something more out-of-the-box? Or is it unrealistic to build all Sage components without tweaking the installation of a standard Solaris system? An interesting question. Doing this on 't2' so it affects everyone (i.e. the global zone) would be a nightmare, as nobody would build Sage. They would lack the tools they need, like a recent gcc. However, if you personally would find that useful on 't2', I could easily create you a new account, with a different user name to do this. To do this as realistically as possible, you would need a new home directory, then set the environment as you see fit. Let me know if that would be useful - it will only take me a few minutes to do. There would be some things available to you, like the Sun compilers in /opt/SUNWspro, which would not normally be available on a new system. To set up a more realistic 'out of the box' setup, it would be necessary to create a zone for this. Also, would it be possible to install Solaris 10 version 1 in a Solaris Zone on T2 so that it would be always one, etc.? (I don't even know if that makes sense.) No, that would not be possible. Solaris zones uses the same kernel as the 'global zone'. When you install a zone, you do not need any operating system disks. Necessary files are copies from the global zone. Zones do not have the independence that programs like virtual box provide. As I pointed out before, virtualbox does not run on SPARC/ Nor would it be possible to run 't2' on the first release of Solaris 10 - the minimum supported version of that hardware is later than the March 2005 release of Solaris. If you wanted to set up a machine like this, it would almost certainly have to be done using a used server, as I very much doubt anything currently sold new by Sun would run on that release of Solaris 10. dave --~--~-~--~~~---~--~~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

Some areas that might need changes are the user interface, the API, scalability, and performance. If there is any plan to do some cosmetic facelift to the user interface, one might find the following blog post helpful: Keith Lang Top 10 UX Myths http://carsonified.com/blog/design/top-10-ux-myths/ I don't _plan_ to do any UI redesign, but I would be happy to consider doing UI reimplementation if somebody could precisely specify what changes need to be made. I iplemented the current notebook UI but I did not design -- I literally just copied the Google Docs UI from 2 years ago. Note that Google Docs now looks different from the notebook because they went through a redesign.

[sage-devel] Re: grant proposal season
sage-devel and Randy, (cc. Kyle Mandli) Chris is working on a Sage spkg interface so that it can be easily installed as an optional package. This raises another licensing-related issue: Clawpack requires the following libraries and Python packages (these requirements are, unfortunately, not well documented yet): gfortran numpy matplotlib farbtastic (listed as GPL, possibly GPLv3) hdf5 (BSD-style) h5py (BSD) I'm not sure how farbtastic fits into Clawpack. The v3 part may be an issue... Also, since we've been using gfortran for most of our compilation, I'm not sure yet how Sage's g95-based Fortran compiler will fare... Now for a development question: should I include automatic svn/hg/git checkout and compilation of the above packages (those that aren't already in Sage) in Clawpack's spkg-install script? Is that the standard procedure for optional spkgs? I can of course include a This will download and install x, y, and z: [Y/n] check during the install process. Since it would all occur within the Sage shell then I don't think it would be a bad idea. (That is, if wouldn't modify the user's system, just the Sage system.) Thoughts? Suggestions? Like Randy said, Clawpack 5.0 is undergoing major changes so that a Sage spkg can be considered possible. This includes major changes in the documentation and website!!! :) If you have any questions then feel free to email me.

[sage-devel] readline trying to open /etc/SuSE-release
The readline spkg-install script is a bit broken, as it has if [ `grep 11.1 /etc/SuSE-release /dev/null; echo $?` == 0 ]; then ... Surely the most sensible thing would have been to check for the existence of /etc/SuSE-release before trying to run grep on it.
