[sage-devel] Sage-related positions at NTU (Singapore)

2011-09-17 Thread Dima Pasechnik
We received a substantial (~500K$) grant for doing a project on the "border" between polyhedral computation, multidimensional moment problem (moments meant as moments of measures), and hard-core numerical computing. We see a considerable part (if not all) of the software to be written done in Sa

Hi! Since quite a long time, #5 is in need of a review. I think that it provides quite useful stuff and should thus soon be added to Sage. Currently, cached_method is implemented in Python, and can be so frustratingly slow that it is faster to not cache simple routines, or to implement a cach

\begin{sarcasm} I'm sure glad that python/sage is so easy to read. \end{sarcasm} I don't see what is going on, so I am guessing that you are doing something different. I was suggesting the use of STRINGS as indexes. Now it is possible that the same name, i.e. string would have different meanings

This change you describe sound like one that has been made for performance reasons. But since it obviously breaks tracebacks I think it should be either undone or made such that tracebacks work. There should at least be made a trac ticket for this issue. -- To post to this group, send an ema
