Free Software

• how come it says "free software"?
  it is very costy, look at http://magma.maths.usyd.edu.au/magma/Ordering/Pricing.html
  • I can't see where "it says" that.

    • words "It is non-commercial software, distributed under a cost recovery licence." sound like it is free to use, while it is not, it requires $1500 and even more for a license.
      • What words in any of that suggest that it is free? "Cost recovery" means that a licence fee is charged to cover costs. But it is non-commercial, i.e., it is NOT produced by a business making a profit. Allansteel 15:52, 11 September 2006 (UTC)
        • They claim 'cost recovery' but I doubt that's true. It's produced at the University of Sydney, which is a public school with a $3 billion (AUS) endowment. It's produced by students as work for their theses and dissertations. This is the same model used by many free (frequently open source) math packages such as SAGE. You'll notice their online calculator is completely stolen (ok, original is gpl and this is non-profit) from an old version of SAGE's.
          The use of open source code and student labor doesn't lead to 'cost recovery' of up to nearly $2000 per copy.Damncrackmonkey (talk) 01:37, 24 December 2007 (UTC)
        • The school of maths at the university of sydney is always short of money. I'm not justifying the cost, but if they made it free, they'll have to find another source of money elsewhere. enochlau (talk) 04:53, 24 December 2007 (UTC)
        • At the risk of confusing Damncrackmonkey with facts rather than unfounded rantings, the School of Mathematics has access to very little of the University's money, and the Computational Algebra Group has access to very little of the School's money. Magma is very definitely not written by students; the core Magma programming team are employed full time to work on it as part of the Magma research project. The Magma license fees do not even come close to recovering the costs of development, to say nothing of distribution and support.
          The calculator page is a web interface to Magma that was originally written by William Stein for that purpose, and provided by him to the Magma group. So it can hardly be said to be stolen. (Let alone from SAGE, which did not even exist at that point. His original version provided interfaces to either Magma or Pari/GP.) Regardless, it has nothing to do with Magma itself, and merely provides an interface to it. --GB 129.78.64.106 (talk) 08:21, 18 March 2008 (UTC)

Proposed deletion

This reads like an ad. Why is it encyclopedic? Septentrionalis 03:07, 6 October 2006 (UTC)

I added lots of the information. My intention was not to make it like an ad. See Mathematica, which gives lots of features of the system too; that looks fine to me. I am interested in adding more CORRECT info in wikipedia on computer algebra; many of the articles in that area have INCORRECT information, written by people who don't know what they're talking about, which is FRUSTRATING. For some of the many things I've fixed in this area (and new comp alg articles I've written), I've added links to these from Magma, since Magma is sometimes the only comp alg system which does them. Also, before I edited this page, it had some some fatuous non-encyclopedic opinions. Currently it is objective in describing it, so I don't see what the problem is. Allansteel 04:13, 6 October 2006 (UTC)

Please relax; I'm not criticizing your edits, I'm sure it was much worse earlier. I came to this article by chance; and comment on what I now see. Accuracy is good; but why is this system notable? Septentrionalis 04:44, 6 October 2006 (UTC)

Well, there are very few general computer algebra systems out there anyway, so any non-trivial system which covers several areas of computer algebra is notable anyway. But Magma is also notable for often having the fastest implementation out there, for many algorithms; that was noted originally (I didn't write the comment that said that; was there already)...

Magma Linear Algebra project

Hi, should there be some form of warning to avoid confusion with the Magma linear algebra project? [1] IRWolfie- (talk) 10:12, 19 August 2011 (UTC)
