In 2013 I bought a Macbook Pro 13” which came with a HiDPI display (also known as retina display). Already back then the support for a single HiDPI display was quite alright with KDE4 and a few tweaks here and there. Months later Qt5 got native HiDPI support and most applications switched from GTK2 to GTK3 and finally the outliers (chromium based apps, godot, arduino…) got support for higher DPIs as well.

Open365 is a public and/or private cloud designed to compete with the likes of Google Drive or Office365 by leveraging all the best free software out there. The service is designed to scale horizontally as well as to be resilient to components crashing or going crazy. In order to achieve this we have implemented a microservice architecure that communicate using a bus (rabbitmq) plus some other tricks so we can scale using commodity hardware horizontally.
