Every AI agent demo looks magical, but most hit a wall in enterprise deployment. It’s not model quality or latency. It’s authorization. Authentication proves an agent’s identity. Authorization defines its blast radius.

The winners in enterprise AI won’t have the most features. They’ll be the ones enterprises can safely trust. Learn how WorkOS FGA scopes that blast radius with resource-level permissions.

Tuomas Hämäläinen, on Mastodon:

We’re at Mac OS 26.4 and seems like the accessibility toggles should be way more considered than they are.

Here’s a comparison between “Reduce transparency” off and on. How does it make sense that turning this setting on actually reduces contrast between the background and the UI elements? Buttons and sidebars get this grey cast, which makes them almost blend in with the drop shadows.

Tahoe looks like Huawei’s rushed rip-off of what Tahoe should be.

Bryan Chaffin, two weeks ago: John Martellaro was good man. He was not only a better man than me, he was one of the best people I knew. It is with a heavy heart that I tell you Mr. Martellaro passed away today. He rose to the rank of Captain in the U.S. Air Force, and h...

I’d never before heard of this museum, but now that I’ve seen Wichary’s photos, I want to go. Unsurprisingly, a lot of his shots are details of vintage keyboards. I keep pausing on this one, a “RE-START” key with the word broken across two lines. It’s clearly wrong but somehow feels right.

I’m linking to his album at Flickr, but he posted a long thread of images to Mastodon too.

More vintage graphic-design weekend fun — this time, a collection of Milwaukee bus tickets from the late 1940s to early 1950s, collected on the Present & Correct blog. So much variety in the colors and typography, but yet they all feel branded together. Think about the care and thought here. Whoever was making these was designing one for each week, every week — and it’s so clear they loved making them. Even something as mundane as weekly bus passes can be exuberant expressions of fun.

(Via Ian K. Rogers, who particularly notes the tickets’ integration of hand-lettering with typefaces.)

Some graphic design fun for the weekend: achingly gorgeous art pieces recreating vintage Pan Am luggage tags, by Ella Freire. I love them all. The colors, the type, the shapes — sublime.

Acting Attorney General Todd Blanche, speaking of the president of the United States in a totally normal way:

I love working for President Trump. It’s the greatest honor of a lifetime. And if President Trump chooses to nominate somebody else and asks me to go do something else, I’ll say, “Thank you very much, I love you, sir.”

The phrase Blanche was looking for is “Thank you sir, may I have another.”

Kottke:

This shot from Artemis II of the Moon eclipsing the Sun is one of the most breathtaking astronomical photos I’ve ever seen. Holy shit.

Follow NASA on Flickr for more.

Update: In a follow-up post, Kottke has assembled a slew of great iPhone wallpapers from Artemis II photos, along with links to other collections, like Basic Apple Guy’s. Also, The Iconfactory has added a bunch of these images to their wonderful Wallaroo app (which is how I’ve switched to one on my own iPhone).

Update 2: Nils Streedain has made wallpapers for the Mac optimized for OLED displays (HEIC native format, pure #000 black background, etc.). Gorgeous.

Not sure why they think this comparison is reassuring rather than terrifying.

I also have to say that Altman’s claims, today, that OpenAI employees were obsessed with COVID weeks ahead of the rest of the world feels more than a little like Donald Trump’s repeated false claim that he predicted, pre-9/11, that Osama bin Laden would attack the U.S.

Zed is a type system that was developed with one question in mind: what do readers actually need? Not what looks good in a type specimen, but what works for the widest possible range of readers. We tested Zed with visually impaired patients at a French ophthalmology hospital and found that Zed Text outperformed Helvetica in terms of reading speed across all patient groups. Designed from scratch to perform different functions, it comes in two optical versions — Text and Display — with four variable axes and support for 547 languages, including endangered ones. It is available directly from the designers.

Apple has shared nine Little Finder Guy videos this week, and on TikTok, the thumbnails for the videos come together to make a Little Finder Guy mosaic on the Apple TikTok page.

I hope this doesn’t jinx the negotiations, but I’m working on getting Little Finder Guy as my guest for The Talk Show Live From WWDC this June.

Sponsorships have been selling briskly, of late. Knock on wood. As of yesterday, the next opening on the schedule wasn’t until the very end of July. However, due to some schedule rejiggering, next week is now open. After that, the next opening remains the week starting July 27.

If you’ve got a product or service you think would be of interest to DF’s audience of people obsessed with high quality and good design, get in touch — especially if you can act quick for next week’s opening. I’m also booking sponsorships for Q3 and Q4 2026, and over half of those weeks are already sold.

My thanks to Material Security for sponsoring this week at DF. Most security teams don’t have a talent problem, they have a noise problem. Manual phishing remediation, chasing risky OAuth permissions, and auditing file shares shouldn’t be a full-time job.

Material Security unifies your cloud workspace, bringing detection and response for email, files, and accounts into one place. It’s security that actually works: augmenting the native gaps in Google and Microsoft without the usual enterprise bloat. Stop fighting fragmented consoles and start focusing on strategy. It’s time to simplify your SecOps.

See for yourself how Material scales.

Ashley Belanger, reporting for Ars Technica:

Using developer tools, the lawsuit found that opening prompts are always shared, as are any follow-up questions the search engine asks that a user clicks on. Privacy concerns are seemingly worse for non-subscribed users, the complaint alleged. Their initial prompts are shared with “a URL through which the entire conversation may be accessed by third parties like Meta and Google.”

Disturbingly, the lawsuit alleged, chats are also shared with personally identifiable information (PII), even when users who want to stay anonymous opt to use Perplexity’s “Incognito Mode.” That mode, the lawsuit charged, is a “sham.”

Everything about Perplexity looks like a scam.
