How China is changing our internet

Yesterday I visited the world press photo award exhibition in Z├╝rich. The exhibition displays the best press photos of recent years.

Below you’ll find a simple approach on how I made my app multilingual using the Redux client state to store the translated content. I assume you are familiar with Redux and React.

Cold Days

Education will never be cheaper while you study (at least in switzerland). This is why I took a photography course at my university (and also to earn cheap credits). The course was mostly about art and history, but nonetheless very interesting. Below, you’ll find my favorite photos.

I liked how the rain covered the handle.
