Zone of Genius

from Alex MacCaw [alt+shift+b] in programming

Aligning the right people with jobs to be done is an age-old problem in company building. And on a micro level, aligning yourself with the right role is also challenging. What should you delegate? Where should you focus your efforts? I've found the Zone of Genius framework to

The problem with US healthcare is not capitalism

Among the world's rich countries, Americans are the most likely to say their healthcare system needs fundamental change. They are right. They are also wrong about why. The standard diagnosis runs roughly: too much capitalism, too much profit, too many private companies, too little government. The corollary is

How to Vibe Code as a Senior Engineer

Over the past few months, I’ve rediscovered my love for building software. Not in the traditional way—writing line after line of code, plumbing together brittle libraries, grinding through boilerplate. Instead, I’ve been vibe coding. Vibe coding is a new way of building software where

We Won’t Save the Planet by Shrinking

At first, it sounds obvious: if we want to save the planet, we should do less. Fewer people, less consumption, smaller footprints. I believed this too—so much so that I once thought having kids was irresponsible. But the more I looked into it, the less sense it made.

AGI, agents, and timelines

AGI is coming—whether we’re ready or not. I’ve been convinced of this trajectory since GPT-3’s release, but recent developments have significantly accelerated my timelines. The first major shift was OpenAI’s breakthrough in test-time compute and its newly demonstrated scaling law.

Pain

I've been staying with my friend Matt Mochary at his house in Hawaii for the last few days. He shared an excellent insight about dealing with pain that I believe everyone should hear. So here it is: We all experience pain caused by others. Perhaps even earlier today

Education Shouldn't Be Held for Ransom

Google told K-12 schools they could turn off AI, but only if they gave up search too. That isn’t integration. It’s holding education for ransom.

AI Assisted Sermon

Once a year at my church, I usually give one sermon. I was asked to tie the theme to a young adult retreat we had taken to the Sunshine Coast. My first experience giving a sermon was many years ago at my old home church in El Monte, California. It was a Vietnamese-American church, but…

Must we always use LLMs this way?

As with my last post on AI, let me open with a statement: Just because most people hold AI a certain way, doesn’t mean that we always must, either now or in the future. As I noted in that piece, and my shades of gray post, I am well aware — and agree with — … Continue reading Must we always use LLMs this way? →

Revisiting Buttons and Cursors

The CSS Working Group resolved to use cursor: pointer for buttons and other clickable form controls in the new appearance: base styles. That happened on October 21, but I posted about it yesterday and, uh, people have feelings about cursors. I wrote about buttons and cursors back in 2022, when a post titled "Buttons shouldn't have a hand cursor" was making the rounds. I admitted I didn't have a strong opinion either way, then argued that not using the hand cursor had become the new anti-pattern anyway. The web isn't an operating system, and people expect clickable things to show a hand. The issue is Cursors For Base Appearance in CSS Forms Level 1. The group adopted the rules from this comment, and the part that's triggering half the Web is: select, option, input[type=checkbox], input[type=radio], button, input[type=button], input[type=submit], input[type=reset], input[type=color], input[type=image], ::file-selector-button { cursor: pointer; } It seems like we have a tabs vs. spaces sort of debate. Again. Nicole Sullivan pulled cursor data from a bunch of design systems and, in September, 27 of the 33 systems that set a cursor used pointer. After she added more systems, it was closer to a 50/50 split. Elika Etemad made the usability case in the meeting. Per the minutes, she said the hand "makes it clear, as soon as you're hovering an interactive control, you're supposed to click on it," and called it a "usability benefit even if not historically done on some platforms." "But the hand means it's a link" Haz had an interesting reaction: The debate is over, and evil has won. His point is that he can't tell whether ⌘-clicking something will open it in a new window anymore. He feels more confident clicking a button when he knows it won't change the URL, like when it just opens a popover or a panel. He's not wrong about that.* I replied that I've been on team evil since 2022 (albeit without a strong opinion, just following what users seem to expect). Touch screens don't have a cursor at all, and on desktop, browsers show a link's URL in the corner when you hover it. That's some type of hint, at least. Haz pushed back that he'd have to watch the bottom-left corner with his peripheral vision, which is fair. He also said he never cared which cursor buttons got, he just wanted links to have their own. I can appreciate that. "But desktop apps don't do it!" Jacob Paris liked the standard cursor on buttons because it makes web apps feel more like desktop apps than websites. My opinion hasn't changed, though. People have already learned that a hand cursor means clickable on the Web. It's by no means mandatory, but it's familiar and satisfying, so it stuck. Either way, nothing changes today. The resolution only covers appearance: base, which browsers haven't shipped yet. Buttons and selects still use appearance: auto, and their cursor is still default. If your CSS reset, design system, or web components already set cursor: pointer on buttons, keep it. When appearance: base ships, controls that opt in will get the same cursors by default. But remember, these are only defaults! You can still add whatever cursor you want to whatever element you want. Nobody's gonna stop you. In 2022, I said I'd keep changing the cursor on buttons until there's a good reason to stop. In 2026, I still haven't found one…and neither has the CSS Working Group. *Thinking about this more, if 50% of design systems opted to add cursor: pointer to buttons already, isn't this already a moot argument? **In general, I think the Web should be more personal and expressive so who even cares about a default? This is especially true for personal and fun sites. Just don't go too crazy, especially when it affects accessibility and the overall user experience.
