    One of my favorite ways to teach programming is using "I do, we do, you do": 1️⃣ I DO: Learners close their laptops to a 45 degree angle, and watch me live code and narrate my thought process. We discuss any questions.

    Sadly, investment in walking, cycling, and public transport will do little to reduce carbon emissions. Why? The road capacity freed up by mode shift will be largely soaked up by more driving. *Pricing* is the only effective way to reduce transport emissions quickly enough.

    I started collecting live GPS data from buses and trains in October and planned to analyse how snow affects the public transportation in Helsinki. But... we’ve had almost no snow this year and it’s February. Damn you climate change! You’re ruining my spatial analyses!

    Every single day I am perplexed by the discrepancy between the everyday experiences and reports of bogotanes in TransMilenio, and the world-wide celebration of BRT and the "Bogotá model".

    One of the most eloquent pieces on why cities should focus on promoting accessibility, not mobility

    People don’t travel just because they want to cover grounds but because they want access to jobs, education, meeting friends etc. Therefore we need to focus on and not in cities. My column in
