Mopidy is an extensible music server written in Python. It provides a lot of different music sources, such as Spotify, SoundCloud, Google Play Music, and more. It’s a perfect open-source solution and alternative for SONOS, running on a Raspberry Pi. It’s nearly perfect for kids, and the only thing missing is a kids-compatible interface. That’s […]

I think we all know, and hopefully love Git. Git is very powerful and even so, a lot of people (including myself) haven’t experienced the full power of Git. I for myself haven’t used reflog or even heard about it for a long time. However, reflogs can probably become really important.
