<div dir="ltr" data-setdir="false">Stay tuned -- As part of next week's Potpourri, I'll take some time (under 20 mins., plus discussion) to outline what's happening and what is supposed to have been done about this problem two decades ago. And what can be done (and is being done) today. Lots of references, so I'll post a document to our Chat on that day. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">-- Bob Primak</div><div dir="ltr" data-setdir="false"><br></div><div><br></div>
