I don't think it's a bad idea to make something partly commercial. From the moral point of view I may cite Richard Stallmann ( http://www.gnu.org/philosophy/selling.html ): Many people believe that the spirit of the GNU Project is that you should not charge money for distributing copies of

Yo ! Seems like some people forget that, you have to play the game in order to be successful. On the other hand, some people think that they need to play some kind of game. Who is the craziest ? The game could broadly be described as: navigating the framework of society. That framework

As far as i understand, the current plan is to spend the money made by SMC (if it makes money, some day) to improve Sage (for example, to hire paid programmers that would work into the windows port). So, if things don't deviate from that plan, the gain of SMC would also turn into a gain for

About William's blog post (*): even though I don't like you do much (but I don't like what a lot of persons do, so apparently there is nothing wrong in that), I was wondering about your plans. If you ever end up earning money with this for-profit company you have in mind, who would you hire to

None of these arguments make any sense. If you want to run a local server with sage, you are very welcome to use the sage notebook that is distributed with sage itself. Also, this thread should definitely not be in sage-devel. On Monday, August 18, 2014 7:45:36 AM UTC+8, Dr. David Kirkby

I think the whole closed source nature is likely to restrict the takeup of Sage for several broad groups of people when they realise that to get high performance they are going to need to store sensitive material on a Linux server they don't control. As a 50 year old engineer I have worked at

As I understand it, the SageMathCloud is closed source. Yet it is making extensive use of open-source code. Maybe the closed source bits don't link to the open-source bits, though I find it a bit hard to believe. If it did not link, it would not that be against the GPL? Or I guess if
