Hi,
this year Sage [1] and lmonade [2] are mentoring organizations for the
Google Summer of Code [3] again.

Hi,
the application period for the Google Summer of Code starts next week.
If we want to apply, we should have a project ideas list ready for
review by Google by February 14th. Here is last year's list:

Hi,
is there a way to see the default owners assigned to trac components?
I just noticed that I am not assigned to new symbolics tickets any

Hi,
I just uploaded a prototype python wrapper for the new library

The main focus of the meeting will be to improve libSingular and the
Sage - Singular interface.
We anticipate a coding oriented event with few talks. Newcomers,

Hi,
we are planning to organize Sage/Singular days in Kaiserslautern some
time in September. The focus will be on the development of
the Sage-Singular interface, and libSingular, but anybody interested
is welcome to participate.
Financial support will be available, especially for the brave who ca
