The point being is that if the client is not returning good results for SaH, it is not that likely that it is returning good results to Rosetta. Aside from what I think are bogus claims as to how much any of my proposal would impact total production the truth is we really don't know what that level would be until the system is in place. I happen to think it is nominal and John by the tone of his posts thinks it is so high nothing else will be accomplished. The difficulty of the extension from your suggestion to mine is so minimal that this is why when I started with your thought as expressed above I made the natural extension. And you know what is the absolute funniest thing... I would wager that if I set up a calibration project John would happily do work for it ... he has done work for just about every project out there ... And that is the even bigger joke, sorry, but he has done work for projects that have no science value what-so-ever ... I'm sorry ... but I love irony ... As to being sorry ... whatever for ... you have a different concept ... the only real difference is that yours is more limited and is not any more likely to be accepted as mine was ... Unlike Diogenes I was looking for a scientist ... an honest one would be frosting ... _______________________________________________ boinc_dev mailing list [email protected] http://lists.ssl.berkeley.edu/mailman/listinfo/boinc_dev To unsubscribe, visit the above URL and (near bottom of page) enter your email address.
