ICYMI, I did a talk last weekend on the open-source Valhalla routing engine, and how the combination of open-source software and open data (via @openstreetmap) give you immense flexibility – even if you're not a software developer!

@ianthetechie @openstreetmap Really nice presentation! Now I wonder, would you have busted out #QGIS if the audience was primary software devs, or would you have given a completely different presentation?
Made something nice: the way from where I used to lived as a child to my primary school (red car, blue bicycle). Neatly segregated networks for each mode. 🙂
