I just tried the SAGE VM module (not the latest) and it only took 50+ secs for the same image. I am still curious about Cygwin though...Dave Cygwin support has been dropped since 2.5.1 or 2. The reason is that many components do not build/work correctly on Cygwin. Up to 2.5.0 those have been not very essential to the normal SAGE user, but since libSingular failed to run correctly on SAGE despite lots of work put into it Cygwin support was dropped. SAGE under VMWare should run faster compared to Cygwin, the only disadvantage is a somewhat bigger download and also somewhat more of an effort to configure the networking via VWMare.

[sage-support] Re: Clearing variables and converting Integers to base(n) strings.
To convert an integers to a base(n) string representation you type yourinteger.str(n) 3.str(2) '11' 50.str(4) '302' On 5/27/07, Ted Kosan [EMAIL PROTECTED] wrote: Hello, I am in the process of putting together a Sage tutorial aimed at high school students and I have the following 2 questions: 1) In Mathematica there is a Clear function that is used to clear variables and an example is Clear [ f, x ]. Is there an equivalent function in Sage that does this? I have been using the var function to clear variables but I was wondering if Sage contained a function like Clear that was more intuitive. 2) In the tutorial, I want to cover using Sage to work with different number bases. I have found that the following code provides a nice general way to convert base(n) string numbers into Integers: x = Integer( '10100101', 2) but I have not yet found a general way to convert Integers to base(n) string numbers. Does anyone know of a general way to do this? I think the binary method in the Integer class is close to what I am looking for and I think that having a more general base(n) method in the Integer class that works similarly to it would be useful.
