Dear Support, That was a very interesting post (and followup on sage-devel). We seem to be having some similar behavior (too many processes and/or all swap memory in use, even with relatively few users) on our (non- public) server, which is luckily set up in a vmware environment on a Linux machi

Hello, A security researcher decided to purposely take down sage.math to demonstrate that it is possible to fork bomb the machine through the public sage notebook servers. I had always plan to run these comletley public servers until something like this happened. Therefore, sagenb.org (and

I think it would be impossible to write an interface to a package you do not (yet) know. Any Sage-REDUCE interface should be written by someone who knows REDUCE very well. They possibly do not need to know Sage so well. John Cremona 2008/10/13 Hazem <[EMAIL PROTECTED]>: > > > Hi William, > > I

Hi William, I am interested in learning REDUCE by using the Sage interface. I don't know if it is a requirement to know REDUCE beforehand, or how well, in order to be able to write the interface. Also, I am a beginning user of Sage and my Python skills are rudimentary, although I have a feeling
