A special request for Stick and other rollers on BGO

Nack, thanks for your reply:

...the version number was 14.3 devel, one that often produced corrupted rollouts (as we discovered only years later -- indeed, some are posted on the navigable early game rollout compendium of this site)... I was referring to rollouts done on GnuBG, not on Snowie.

Uhh oh!

...keeping the version number documented with posted rollouts whenever possible [is a good idea]... as long as there is not a significant inconvenience tradeoff

Good point. In XG, the version number is automatically appended to a rollout. You have to do extra work to delete it. According to Tim's message, however, the version number is the one used to export the rollout, rather than the one that did the rolling. Usually, the two versions will be the same, but perhaps XG should record the version number of the program that does the rollout in the file along with other rollout data.

By comparison, GnuBG does not display the version number in its rollout. You must do extra work if you want to include it. This is a problem. A simple tweak to the report routines would at least get GnuBG to the place where XG is today: it could display the version number of the program that produces the rollout report, even if it were different from the one that did the rolling.

For both programs, it is a much more difficult step to redefine the file format so that version numbers are recorded with rollouts.

It is only when corruption exists for a posted rollout and that corruption is discovered/suspected after the underlying rollout is lost, if ever lost, that regret for not posting the version number occurs.

Uh,... yes, but not all the readers of BGO have access to the original rollout files. We cannot check them. We must rely on what is posted. Even when Stick has the information that one or two or many hundreds of posts are corrupt, it's unfair to our generous host to expect him to rewrite the history of the site.
