Well, let me refer you to the posting on 5/29 under the heading Re: Uneven Hardware by Robert Hyatt, and I quote: "If program A on hardware B beats program D on hardware E - does that say much about A compared to B? This belies the principles of science - you have to have a uniform platform for all participants to make any kind of judgement". Now, Mr. Young, do you get the point? Or do you believe that Mr. Hyatt also doesn't know what he's talking about? Hmmm??? By the way, my opinion on this matter was posted BEFORE I found Mr. Hyatt's statement quoted above! >> >>Mel >>>> >>>>Venlig hilsen >>>> >>>>Hans Chr. Lykke >>>>http://home3.inet.tele.dk/hclykke/
