Well, I did it. It took a while to get over the feeling of not having much useful to contribute. (Which was probably accurate) But, if there are some struggling windows users that are helped by it, that makes it worth it. It was also a new learning experience. So struggling windows users, che

Ok, for those of you who saw my recent message about the illegal instruction ... I think I now know why that doesn't work. I think it is that the latest sse2-3.4.2 virtual machine does not support my processor (AMD Athlon 64 3000). I don't know why, since this cpu does support sse2, but perhaps on

I was under the very vague impression that computer algebra systems a la Maple, Mathematica etc. were so-called because they started out emphasizing algebraic and symbolic manipulation, and so came out of the so-called "computer algebra" community, as opposed to systems that started out relying mo

Just downloaded the lastest sage for windows virtual machine as well as the latest vmware to run it. Wow, 700Mbytes and yet no clear instructions on how to run it! I tried double clicking on sage_vmx.vmx, then at the sage login prompt I typed "login" and then "sage" for the password, and then "sa
