Re. Rybka 3 source code: Unfortunately, I don't have it. (Yes, it was careless. I'm keeping the Rybka 4 source code.) It's not necessary for writing up the Ippolit case, but it would probably make a court case more difficult.

Best regards,

Vas says he doesn't have the source code for Rybka 3. Surely he doesn't mean he lost it. Did he just sell it to Chessbase or something? Is that what he means? Even so, why would he be so "careless"? What does that mean? Careless in losing the source code? Careless to sell it to someone?

He says he's keeping the source for Rybka 4, but doesn't have the source for Rybka 3. Therefore, Rybka 4 must have hardly any code from Rybka 3.


I can actually buy that particular point. Years ago, somewhere in the later 90's, I had a disk failure where one of the internal platters actually shattered and cratered the entire drive so that even a recovery company said "no can do." We had been doing backups for a couple of years using a SCSI tape drive. It never reported any sort of error, and we had so few file losses (mostly students removing files by accident) that we didn't use them very much. However, when my disk crashed and I replaced it, we discovered that not a single one of our backups of my files was usable. Not a one. As a result, I lost a ton of stuff, including every crafty version from 1.0 forward (I now have maybe 3-4 versions prior to 13.0 that others saved for various reasons). I lost all of my carefully saved Cray Blitz log files from various events we had participated in over the years. Copies of programs like chess 4.x, Coko IV, and you name-it.

So I can buy that given the right set of circumstances that source could be lost. I now have copies of everything on my office machine, our office NFS server, and on ny laptop, plus a few DVD backups here and there. Hopefully at least one of those survives the next catastrophic failure. Smile
