-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi guys, After encountering the same problem posted here[1] (awk's rand() not "random" enough), I did some research. It[2] shows that awk(1) in OSX is currently using random(3) instead of rand(3), the same in gawk(1). Changing rand(3) to random(3) only requires modifying a few lines of code, but will result in better random number generation. So why not? :) [1] https://forums.freebsd.org/viewtopic.php?&t=6456 [2] http://www.opensource.apple.com/source/awk/awk-18/src/run.c - --- Chenguang Li -----BEGIN PGP SIGNATURE----- iQIcBAEBCgAGBQJT/YkwAAoJELG4cS+11lRhocUP/0+n4I2SYNZ45VQOfWkgZZhu Wqx4zG273ddkvfZs4nXpvTLJDlHz0PLQXF/hbi8/RH4gcaOubAF0wTZz5zAkpczN JdK1WSi9yFpb6U8dsVJaeay7CxUrv+kBUKzWz92Fg1YH9ZsGskbTYsFJUqH2TiwL OzOvRDUodxGb5NPcCnys9c2Cb0v5/nffwnanDiRXsVyyYrVAr/ALmY5qSue4OoeY PL7u56jYpX98YuPVCDTrRtVZaPkaNVyduVUWLYTRaMjyu5TbN3yhE29HssvXBFsD wK7p3slC8o3aAdopmxv8ne4NI+OkKU4ukxhuDAr1jcIy+Uhmxz+2ZJmjrSTEr+Ff 5K1/WFCWx9c9XLDSHQFJKkouRDLJSHQJxZVostDrBIz9cXqtWWafesf4VvEzWMwx 41Aq5AAVDpQMjaymLaHF11hdyhzVHzS2G2rkn6BLtM32baJJZk8XP0PZp7o11ldJ l7xZnLQ7L4sFCyBwZx2PHLed52SKBSzMhj9ejVf+NICeTk3ZlQP2c2ZGbu87rghH YJTC/1PTV5vufaPE5P644o/r4t3PSdLo4s+ngdv946NggV8JSBxkP6FcjTXiwSMn VEphdAI3Luk7F1IIBhDywYbDe6LkiJ+tGfN1gDpcNGcciYU1E/0noCIoAJyn3h6s QbQ7hRf6iARh2YzA16t1 =It9Y -----END PGP SIGNATURE-----
