Design Objective

UI backwards compatibility Entirely agree, we need do better with breaking UI changes:

The case for the case for UI backwards compatibility is arguable weaker than the case for API backwards compatibility because API backwards compatibility has a lower cost – if some API is problematic, you can make a new API and then document the old API as something that shouldn’t be used (you’ll see lots of these if you look at Linux syscalls). This doesn’t really work with GUIs since UI elements compete with each other for a small amount of screen real-estate.

And also often overlooked:

An argument that I think is underrated is that changing UIs isn’t as great as most companies seem to think – very dated looking UIs that haven’t been refreshed to keep up with trends can be successful …

The Neural Net Tank Urban Legend TL;DR 50 year old urban legend, that gives a misleading indication of risks associated with deep learning:

Bitcoin Is a Bad Way to Do Something Necessary TL;DR Bitcoin is a "first mover advantage" currency, which favors very specific subset of the population. And also:

It’s great that you did something wonderful 40 years ago, but what you do today should matter more.

Getting Users Psych'd—User Psychology for Better Onboarding Designing great on-boarding user flows starts with this principle:

Keeping track of how much psych a user has at any given time will inform the way in which you nudge them along in a given user experience. If their psych is high, then they're in a position to take in more information. If their psych is low, then they need to be pointed to value, gaining immediate satisfaction from their engagement.

There’s No Fire Alarm for Artificial General Intelligence 🤔 interesting perspective:

What is the function of a fire alarm?

The fire alarm doesn’t tell us with certainty that a fire is there. In fact, I can’t recall one time in my life when, exiting a building on a fire alarm, there was an actual fire. Really, a fire alarm is weaker evidence of fire than smoke coming from under a door.

But the fire alarm tells us that it’s socially okay to react to the fire. It promises us with certainty that we won’t be embarrassed if we now proceed to exit in an orderly fashion.

  • z-index values must be declared as global variables in a central location

I wish 'DRY' wasn't such a dogma in programming. Somethings would be better off repeated and explicitly stated. Intent can be more clear.

Lindsey Bieda But more importantly 🔨:

No design pattern or software design principle should ever be taken as a MUST. When you stop being thoughtful about what you are coding you stop being active in the process.

Enough With the Service Objects Already Speaking of pattern over-use:

An object that handles business logic but doesn’t have a well-defined business domain role is like one of these dangerously-located seedlings. Objects tend to grow and accumulate more responsibilities. As Corey Haines puts it, objects are attractors for functionality. And once they mature, objects with confused, ill-defined roles can be some of the hardest to refactor.
