I was just wandering on the net in the night on Medium. I like doing that, I have some particular “streets” where I love to hang out when I have nothing to do. Primarily this aimless activity is to get the vibes on the ground. And yet again I discovered a gem in my wanderings. A very interesting website on UI and design. It is a community for designers, developers and creative entrepreneurs with a passion. Hacking UI
It contains very interesting sections on tools (Sketch etc), UI principles, trends in UI, UI events and much more. What I like most about this website is there newsletter which sends out a dossier of actionable news in the design domain. Also, they do some interesting surveys, in particular, i liked 2016 Design Tools Survey .
There are tons of other resources and materials that you can make use of. I highly recommend you to check their website and also subscribe to there newsletter.
Love from Singapore to the founders Sagi Shrieber & David Tintner !
