In the interest of balance, last week Microsoft donated USD $5K to support the Women in Sage Days conferences. This new Ubuntu in Windows initiative is really fantastic. I'm glad they (evidently) now support fork and pseudotty's -- they didn't when somebody tried a few months ago, and I heard that this was their top priority. Regarding the above discussion about speed, what combination of OS/Virtualization/Emulations/Native/etc. is actually fastest is not something that can be determined by "pure thought", since there are two additional factors (which I saw a lot in work of Bill Hart, Jason Moxham and Brian Gladman on MPIR and FLINT): 1. Performance is multidimensional. It can easily be that f(X) is faster in one setting, whereas g(X) is slower. Or even that the relative speed of f depends on X. 2. Performance depends enormously on how much work has gone into optimizing libraries for certain platforms. E.g., once when I tested using MPIR in Linux via VirtualBox on Windows, it was much faster than just using MPIR natively built using MSVC (no claims about today). Why? Much more effort had gone into optimizing MPIR on Linux than on native Windows. -- William -- William (http://wstein.org) -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
