Please consider the following problem. We have some kind of questions bank which we stored in spreadsheet like Excel or anything similar. One day, we want to create an online quiz with Google Form based on the questions bank we had. How can we generate the online quiz in easy and fast way? By using Google Apps Script we can automate the task of converting the questions from Google Spreadsheet into Google Form. The script will generate the final Google Form which we can use and share to our respondents later.

OpenStreetMap is a very good crowdsourcing map application. It has a cool feature which tag the road in the map by its type. That feature enable us to identify the type of road such as main road, pedestrian road, living street, etc. Besides that, we can also use that feature to extract only the road part from the map. This can be useful when we want to build a routing system which need the road part only.
