Hi Jan, Yes i do use a proxyserver. I did make some changes in a couple of *.conf files as suggested by the CentOS team but it seems that it is not yet complete for sage to upgrade flawlessly. I'll browse some more and try to rectify the problem. I'll report failures or successes soon. Thanks

Most of my needs in this area are taken care of by the support for the Cluster library in the optional package biopython, but since I have some interest I tried to make a preliminary spkg: http://sage.math.washington.edu/home/mhampton/MLPY-2.2.1.p0.spkg Unfortunately although GSL is a standard

[sage-support] Obtaining data from a computation in process

Hello! I have a computation running in Sage. It is a search of more or less the following form: Let S be an empty set. For i in some interval: Check some property for i If i satisfies the property: add i to the set S. I now realise I should have said print i rather than add i to the set S.
