More specifically, web projects.
I'm a front-end web developer who's looking to brush up on back-end development. Stuff like Rails, Node.js, Ember.js and so on.
I've been trying to work out what to build next, but I have writers block and it's very frustrating. I'm not expecting anybody to give me an idea, but I was wondering if there's anything I could or should be doing to muster up some ideas.
If it isn't a problem that you actually have, then it probably isn't worth solving. If it isn't a problem you actually have, it's likely going to be much harder to solve (even if it exists).
If it's a real problem that you have, it's likely that somebody else has the problem too. After you identify the problem, it should be easy enough to ask around and see who else has the same problem.
