I stopped writing blogs after my last one, the one where I pointed out that some in the MD world aren’t paying close attention to the scientific principles of test and verification, mainly because there was so much resultant negativity. Of course, that’s nothing new in my career! But at OpenEye we’d started in earnest on Orion, our cloud platform, a journey that’s been rewarding but all-consuming. Write laments that really don’t do any good or go make something you really believe in? Easy choice. It’s one my erstwhile mentor, David Weininger, would have approved of. Dave, who died on Wednesday morning (prior to the election results!), never had much time for communities, other than those freewheeling ones he created for himself. And yet, or perhaps because of this, he had more impact in the field of chemical informatics than anyone since, well, Kekulé.
