Surfing around in the web is a daily routine every developer should have. Learning about new platforms, libraries or techniques is a must, due to the tremendous speed on our business. Stay current, all the time.

I’m a fan of RSS and I’m using Feedly to read my favourite blogs. Unfortunately RSS feeds is not so common anymore, due to Facebook and other social media giants, but I stay informed.

In this series I present some of the absolute pearls I found while reading. Stunning solutions or incredible tools, which I must first and foremost remember for myself, to try them out one day.
