New web tutorial
by stepharo Dec. 16, 2015

Dec. 16, 2015

Hi guys with Olivier Auverlot we did several attempts (over the year) and we are happy to release a first draft of a web tutorial around Pharo. We ask the user to build a simple blog engine. It goes over - Mongo - Seaside - Magritte https://ci.inria.fr/pharo-contribution/job/TinyBlogTutorial/5/artifact/book… Soon Rest/Deployment/Garage?/NeoJSON/XML If you want to participate (translate it to english) or improve it you are welcome. We hope that it will serve as a basis to a lot of Seaside applications. This tutorial will be used in the lecture I'm giving next weeks in Togo and will be edited as a lulu book. Stef and Olivier.
