I love this image. It appears to be a reasonable house with a reasonable layout but the longer you look at it the more you realize how poorly it's designed.
This house would be terrible to live in. Building software isn't hard. It's designing it to be livable and maintainable, that's the hard part.

It feels really good that this client was built using the same framework I designed for the in editor client I built for VS Code.
Sure it had an Axum API but it's reusing the functions and types already in place. My initial design for that stuff just worked and that feels fucking great.

So I have slept in ARIA for test automation purposes 😵💫
I mean making your app more accessible to more users is already a huge win but holy hell it makes automation a fucking breeze.

Lots of UI improvements, refactoring behind the scenes, and screenshots added to the README!

I've also seen a lot of debate in component libraries versus "plain HTML" but the thing is many component libraries have ARIA support out of the box.

I really do love the spec style syntax for tests (describe, before each, it). When used correctly it's the best at representing test setups and expressing test intent.
I also recognize it has many downsides that have to be accounted for.
Let me tell you, it really sucks resolving merge conflicts.

This weekend's project was adding the ability to edit requests. I was already putting it off due to complexity but it turned out to be even more complex than I realized...

I've been using tanstack query for a while now. I really like it but I'm running in to an issue I don't quiet know how to tackle.
I have a use case where I'm firing a mutation off and I need away to call an "onSuccess" callback that I don't have at mutation definition time.

Is there interest in a Twisted Metal 2 like game? Gameplay wise that is.
I've seen the genre make a little bit of a comeback but they've haven't felt like TW2, the gold standard of the genre, to me.
I was working on this game a few years back and thinking of reviving it.

I signed up for a local gamejam after not touching game development for over a year (maybe two years now?).
We'll see how this goes 😅

You call it "over-engineering" when devs make software more complicated than it needs to be.
But simpler solutions often require *more* thought. Complexity's easy. You just keep typing.
That's why I call over-complicating "under-engineering".

Prefactoring, doing the refactoring work (as a separate change) that makes introducing a new change easier, is such a powerful tool that I rarely ever see in action even from more senior devs.

A couple years ago I would have said no way!
Digging in to language design and actually implementing some programming languages definitely changed my view on this.
I actually like the syntax for index access on an array being the same as a function call.

Thus, using abstraction in "coding at a higher abstraction level using AI" doesn't really make sense. It might be something different, but it's not an abstraction.

An abstraction having a property of being indeterministic cannot be an abstraction.
If an abstraction is flaky (different from leaky) it pulls you back into the details to understand if it abstracted the thing in the way it should've abstracted.

The constant threat of last minute investor demos created the developer and tester that I am today.
Me, in my first real role at a startup, experiencing "move fast and break things" in action:
"We are pushing to production. Any uncommitted changes will be lost."
"uncommitted changes will be lost"
"uncommitted changes"
Investor demos were later THAT DAY.
