I think the trick is to shed your imposter syndrome, but remain humble. You can be confident and humble at the same time. It can come with accurate self-assesment. Keeping your weakness in mind helps a lot.
How would you recommend becoming familiar with idiomatic Go?
I've read various articles including (but not limited to) tutorials, made a point of exploring a few open source projects and I've written a few thousand lines of Go. I enjoy writing Go, but I have a hard time so far figuring out if what I write is idiomatic.
Right. I read that, and in hindsight should have used more inclusive wording. Anyway, I really like Feedbin even though it could use a bit more polish (a couple of animations would go a long way e.g. when it is loading an article).
Sort of. You can rearrange the task circles, but they float into a somewhat arranged layout. In practice this means that the order is not immediately obvious.
The circles actually seems to reduce value because there is no intuitive order to each group. In some (many?) use cases for Trello, priority is important.
One thing that the circle metaphor does add is nested groups, which I can see being important for a different set of use cases.
I've heard a few times before that the iOS keyboard invisibly grows the touch target on the letters it predicts are most likely to be typed next. Unfortunately, my quick attempt to find a source failed.
Potty training; put baby on the toilet before the diaper gets wet. Babies can be "trained" a remarkably young age, if the parents can predict urination.
I personally find it useful to have a plankton mode and a shark mode, switching between them as necessary. Drifting is useful at times, but you definitely miss out on many of the best parts of life if you don't push yourself.
Don't get distracted by the politics and fighting in the mobile space. Work on what you love and enjoy.
My suggestion: start with native app development for the device that you own and use most. Run through a couple of beginner tutorials and write a few toy apps. This will give you a more solid foundation for making decisions. (I would not recommend using cross platform tool-kits until you understand the trade-offs.)
Then, I recommend that you build one of your ideas for the same device and release it. After releasing it, you can either move on to the next idea or port it for the other platform.
The idea is for the light to be definitive, but I am not sure how secure they are. Also, as far as I can tell/remember all Macs have indicator lights on their cameras.
