2015 FOSS4G Track - Building Lightweight Mapping Apps with Esri Leaflet by An...GIS in the Rockies
Learn how to use Esri Leaflet to quickly develop fun, lightweight web mapping applications. Esri leaflet is built as a series of API plugins for the hugely popular Leaflet open source mapping library. In this introductory session you’ll learn how to use this simple and intuitive API to work with basemaps, mash up data and consume ArcGIS feature services. You’ll also walk away with an appreciation of how easy it is to apply basic cartography and custom styling to features.
Each technological age has been marked by a shift in how the industrial platform enables companies to rethink their business processes and create wealth. In the talk I argue that we are limiting our view of what this next industrial/digital age can offer because of how we read, measure and through that perceive the world (how we cherry pick data).

O App Engine (PaaS da Google) foi por algum tempo uma das plataformas mais simples para se começar um produto na web, pela facilidade e abstração que oferece, fazendo com que o desenvolvedor não tenha que se preocupar com dificuldades técnicas normalmente encontradas em outras plataformas do gênero. Nesta palestra, vamos falar sobre porque no Trainee World (http://www.traineeworld.com.br/home) optamos pela migração para o framework Django e o serviço de hosting do Heroku. Quais são as vantagens e desvantagens? Vale a pena?
