But sometimes not even that helps; the onceability factor can, ultimately, trump the usefulness.

If you think that for every problem there is a simple and easy solution, either you don't understand what is a problem or you don't understand what is a solution.

For the $$$ question, nothing comes to mind. These problems i'm hitting up against are larger than a contractor could solve in a few hours of work (which would be hundreds/thousands of dollars).

Progress is slow though. I want to change how assets are loaded, the current implementation of "pipelines" is challenging to work with.

I'm not sure about all consequences of my change and this is very complex.

Validating forms has notoriously been a painful development experience. Implementing client side validation in a user friendly, developer friendly, and accessible way is hard. Before HTML5 there was no means of implementing validation natively; therefore, developers have resorted to a variety of JavaScript based solutions.

Redesigning the pieces was very difficult work, because traditional pieces have 4 specialties below.

we also wrap them in Failure to solve the second problem: spotting potential exceptions is hard

It turns out that, given a set of constraints defining a particular problem, deriving an efficient algorithm to solve it is a very difficult problem in itself. This crucial step cannot yet be automated and still requires the insight of a human programmer.

It is difficult to come up with content that is not extracted from a real application. Manufacturing scenarios to see if ideas have practical application turned out to be an exhasting and time consuming process.

I don't see a way to hook into Devise's route mapping load process to add the action (several monkey patching attempts failed)

violates our expectation that hard things should be technical

the 2 hardest problems in computer science are essentially the 2 hardest problems of life in general, as far as humans and information are concerned.

I think you’re missing the spirit behind the classic “centering is hard” complaint in a couple of places, which, at least for me, always comes back to not knowing the height of the elements.

They say that there are only two hard problems in computer science: cache invalidation, naming things, and off-by-one errors. Caching is what Service Workers do. It’s literally the #1 hard thing! … or maybe the #0 thing? Whatever. It’s hard.

If you want to implement a form with a superb User Experience, you have to take care of many variables:

This does solve the problem, but now our project and API is structured differently. In large projects it might be very hard to determine how to pull this trick off, or even impossible!

It adds a few constructs to the language to solve one of the most complex problems in UI development — state management.
