Dear GeoGebraCAS friends, let me introduce you to Ted Kosan <ted.kosan@xxxxxxxxx> (Shawnee State University in Ohio, USA), a new member of our GeoGebraCAS mailing list. As you know we are basing our GeoGebraCAS on Yacas. Ted has decided to fork JavaYacas into "MathPiper" because it was not being maintained and none of the Yacas developers seemed to be in a position to move it forward again. MathPiper will essentially be an improved Yacas where Ted can help us to fix bugs in the future which is very important of course. We will soon switch from Yacas to MathPiper internally. I am very happy about Ted's enormous efforts and am looking forward to good collaboration in the future. Ted, welcome to the GeoGebra community and thanks for your great work! Best wishes, Markus -- Markus Hohenwarter, PhD Florida Center for Research in Science, Technology, Engineering, and Mathematics Florida State University, www.fcrstem.org GeoGebra: www.geogebra.org IGI: www.geogebra.org/IGI
