Anything else is not acceptable IMHO. certainly, I don't want to be the idiot that weeks after the OpenSSL +Debian debacle does something equally stupid and hence will be know in Slashdot lore as "that GNUTLS idiot" ;). It might in the end be a config problem since on Solaris with Sage 3.0.1 upon the start of sage the process just sits there polling /dev/random for well over two minutes and nothing happens, i.e. I always killed it. I will now let it sit there for a while and see if it comes up. Aside from that there is a problem on that box due to some background jobs being way too high in priority so that I only get a small default slice of the CPU. I will pause the background processes now and see if that makes a difference. Aside from that it would be good with somebody with deeper Solaris- internals fu than me could enlighten me if /dev/random is the preferred source of randomness. On linux at least /dev/urandom is supposed to be a "better" source of entropy, but I could be wrong about that. And a last note: I also need to remove a bad fix for libfplll that Paul had pointed out to me a while ago as wrong, i.e. my round fix for Solaris did stupid things for numbers smaller than zero. It isn't needed on Solaris 10 and higher, so I plan to remove it since we as it looks now will only support Solaris 10 and higher anyway. > Martin Cheers, Michael > -- > name: Martin Albrecht > _pgp:http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x8EF0DC99 > _www:http://www.informatik.uni-bremen.de/~malb > _jab: [EMAIL PROTECTED] --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
