Hi, In a few weeks I will give a speech in Taiwan at NCHC[1] about Pharo, my intend is to present release 4. I already did speeches there in the past about Pharo, but I have a hard time to raise interest to the point people want to jump in. But I hope to have an angle this time because NCHC recently offers a server and the hosting for an openstreetmap tile server (the first in Asia by the way), and there is high interest here in Taiwan about OSM related stuff. I read here, job has been done with Roassal and OSM, but it is not clear for me how to get in using OSM within Pharo. I am particularly interested in providing an interactive demo where live programming shows its value. I have found these pointers bellow. I am interested by any additional tips and url, and particularly the compatibility with Pharo4. https://github.com/fstephany/OSMMaps http://pillarhub.pharocloud.com/hub/ThierryGoubier/5y08m9uu71o8i7a35ijwr766p Thanks Hilaire [1] https://en.wikipedia.org/wiki/National_Center_for_High-Performance_Computing -- Dr. Geo http://drgeo.eu http://google.com/+DrgeoEu
