My thanks to WorkOS for sponsoring this last week — a big week — at DF. SSO is table stakes for enterprise deals, but building it into your app yourself means writing SAML controllers, parsing XML assertions, and handling IdP-specific quirks for each provider. Learn how SAML flows work, the tradeoffs between building or buying, and best practices for security, routing, and UX. Or, skip the hassle and add SSO with WorkOS . Read their developer’s guide to learn more . ★

He takes the same “ this is pretty much exactly what Apple used to label an ‘S’ year ” angle I did, so, unsurprisingly, I think his review is spot-on. Brownlee emphasizes one point that I should have, but didn’t: according to Apple’s published specs, the regular iPhone 18 Pro gets longer battery life than the iPhone 17 Pro Max. That’s just a year-over-year spec that anyone can understand, for an attribute that everyone cares about. ★

iPhone 18 Pro: A Photographer's Review
Uploaded 19 September 2026

Cleaning up my notes this morning, I realized I forgot to write about the new under-display Face ID sensor in the iPhones 18 Pro, and the corresponding change to the Dynamic Island. I just added it to my review. For those of you who’ve already read the review, here’s the new section in its entirety: A Smaller — or Is It Bigger? — Dynamic Island Apple moved the Face ID infrared camera under the display. It’s up in the top left, underneath the area where iOS displays the time in the status bar. This means that the dedicated black cutout for the Dynamic Island is now noticeably smaller. But it al

Miriam Pawel, in an op-ed in The New York Times arguing that University of California should not bring back the SAT requirement for admission: What has made the University of California exceptional is its commitment to increase access without sacrificing excellence. [...] Students on University of California campuses may struggle with basic math, but they are graduating at record rates. A success story would be increasing the number of people with solid math skills. Printing degrees for students who struggle with basic math is not a success story, and sounds like the antithesis of “academic ex

Will Oremus, writing for The Atlantic last week, “Okay, Sure, a Folding iPhone” (gift link): Apple’s next big invention, the company revealed at a launch event in Cupertino, is a $2,000 iPhone that sports — get ready — a “remarkable hinge.” Is it not possible for a hinge to be remarkable? This is the iPhone Duo, a foldable gadget that opens like a book to reveal a capacious 7.6-inch screen. Billed as the most versatile iPhone, it can be used in folded or unfolded form, and in split-screen or full-screen modes. The screen appears seamless when open, which is a clever engineering feat. Yet an iP

Every year since 2007, Apple has debuted a new flagship iPhone. Other than the just plain “iPhone” original, they all have numbers of some sort in their name. If you make a list of them in order, it’s a bit of a marketing curiosity that the only one of the bunch whose number in its name corresponds to its generation number is the iPhone 4 , which was in fact the fourth iPhone. (The “ten” in iPhone X marked 10 years, but it was the 11th flagship model.) The iPhone 18 Pro, in fact, heralds Apple’s 20th iPhone generation: Flagship Year Milestones 1. iPhone 2007 Holy shit 2. iPhone 3G 2008 3. iPho

★ The iPhones 18 Pro

Joe Rossignol at MacRumors over the weekend: Apple now says the iPhone 18 Pro has a C2 modem worldwide, while the iPhone 18 Pro Max uses the chip in every country except for the U.S. [...] Apple has yet to provide an explanation for this modem difference, so we can only speculate for now. In 2023, Qualcomm announced that it would supply Apple with smartphone modems through 2026, so perhaps Apple is equipping the U.S. version of the iPhone 18 Pro Max with a Qualcomm modem in order to honor this agreement in a minimum way. Apple’s C2 modem supports ultra-fast mmWave 5G in the U.S., unlike its pr

Joe Rossignol, MacRumors: Apple just seeded the first beta of iOS 27.2 to developers for testing. Yes, you read that correctly: iOS 27.2, not iOS 27.1. Why no iOS 27.1 beta? The answer likely relates to the iPhone Duo. This unusual version numbering is entirely about the Duo. The Duo is on its own fork of iOS — heretofore to keep details about its software secret / internal to Apple. When it launches October 23, Apple has already announced it will ship with iOS 27.1. Apple is thus using 27.2 as the version number for the first post-27.0 updates to all of its OSes for devices other than the Duo

In my long take yesterday on Apple’s event last week, I wrote that when you pay $20 extra to get the $150 AirPods 5 With Wireless Charging Case, that the case is compatible for inductive charging with “MagSafe, Qi, or Apple Watch pucks”. But the compatibility section of Apple’s tech specs page for AirPods 5 doesn’t list MagSafe: Works with USB‑C connector, Apple Watch charger, or Qi‑certified chargers That’s because for Apple, true MagSafe compatibility means magnetic attachment. The AirPods 5 case doesn’t have magnets; AirPods Pro cases do. So when you charge AirPods Pro with MagSafe, they sn
