If you hang out with compiler writers more often (I do, about once a year, thanks to an old friend who implements superscalars) you'd find that they've felt the same way for years (and spend a good bit of time with machine learning algorithms working on weak points, discovery, and optimization). (staying off topic, it's also amusing that some of the better groups generally run on relatively ancient hardware, but that's another story). best, -tony -- [EMAIL PROTECTED] http://www.analytics.washington.edu/ Biomedical and Health Informatics University of Washington Biostatistics, SCHARP/HVTN Fred Hutchinson Cancer Research Center UW (Tu/Th/F): 206-616-7630 FAX=206-543-3461 | Voicemail is unreliable FHCRC (M/W): 206-667-7025 FAX=206-667-4812 | use Email CONFIDENTIALITY NOTICE: This e-mail message and any attachme...{{dropped}} ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-devel
