[Sponsor] WorkOS: How SSO Works and the Fastest Way to Add It

workos.com/guide/the-developers-guide-to-sso?utm_source=daringfireball&utm_medium=newsletter&utm_campaign=q32026

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.

Miles Abbott:

Open x.com links in a popup so you can read the one post and leave. Port of the Litterbox Safari extension.

Litterbox is a cleverer name, but Dumpster Fire is funnier.

XCancel Shuts Down Again

xcancel.com/

XCancel:

Unfortunately, due to a new development in the ongoing legal proceedings, we are required to suspend this service again until further notice. We can’t share more details.

Not surprised, and not sure what to make of the “can’t share more details” part. Again, if you want to avoid visiting X but want to see the content posted there linked from other sites (and, let’s admit it at this point: there’s not just a lot posted on X, it is outright resurgent in popularity), install a browser extension like Litterbox (Safari) or Post Peek (Chrome).

Unread 5.0

goldenhillsoftware.com/2026/09/unread-50/

John Brayton:

Unread 5.0 is available now from the App Store. This update adds these improvements and more:

  • Improvements around hero images, article list thumbnails, and widget thumbnails
  • Syncing with FreshRSS and Miniflux
  • The ability to quickly mark old articles read

I’m a NetNewsWire man personally, but I’ve long admired Unread as a different, very good take on a feed reader. Just a gorgeous app. One of the very best things about RSS is that feed readers take such different shapes and approaches.

Where Are the AI-Generated Killer Apps?

nytimes.com/2026/09/12/opinion/ai-software-coding-apps.html?unlocked_article_code=1.AlE.C9EE.H2j5a1eHFUbQ&smid=nytcore-ios-share

Paul Ford, writing for The New York Times (gift link):

For a while, I must admit, it looked as if software developer roles like mine were done for. How could we fight against tireless robots? But our industry is slowly realizing that making truly cutting-edge software still requires humans to think and work together, to maximize their skill sets and to practice their respective crafts. A.I. can write very good software, but it also makes it easy to do someone else’s job badly, which is part of why all those projects fail. Now that everyone can code, it’s become clearer why many shouldn’t.

Ford, linking to his own column on Bluesky:

I just want one killer app before we get a killer robot.

Yours Truly on Off Protocol With Jim Ray

atproto.com/off-protocol/2026-09-11-make-your-own-thing-john-gruber

My old friend Jim Ray now runs developer relations at Bluesky, and part of that gig is hosting a podcast, Off Protocol (“a show about building a better Internet”). I was delighted to appear as his latest guest. I generally don’t like talking about my career, but I did enjoy talking about it with Jim. He has that effect on people.

Benjamin Mayo, 9to5Mac: Many have complained that Apple design has been sapped of some of its trademark whimsy in recent years. Well, here’s the latest example of how the tides seem to be changing. Buried in the Settings app on iOS 27, Apple has hidden an easter egg tha...

XCancel Is Back

XCancel:

Following the legal progress as announced in the Nitter GitHub project. The XCancel service is resumed.

More details will be shared on the Nitter GitHub project page.

Glad to hear it and I wish them well, but I think Zhenyi Tan’s Litterbox Safari extension is a much better solution for viewing tweets on X without going to X.

Apple’s OS 27 Updates Will Be Released on Monday, 14 September

9to5mac.com/2026/09/09/apple-confirms-macos-27-golden-gate-launch-date-september-14/

9to5 Mac has the iOS 27 release notes too. I haven’t spent much time using Golden Gate, but I’ve been using iOS 27 full-time ever since WWDC. It’s in excellent shape for a .0 release.

Now I need to think about how long I want to still hang onto MacOS 15 Sequoia on my main Mac. I’ll probably skip 27.0 and wait for 27.1, but maybe I’ll bite the bullet and upgrade when a 27.0.1 update comes out.

Joanna Stern on the iPhone Duo

One thing I learned from this video is that I’m way, way too careful when playing with the hands-on area demo units. I handle them like museum pieces; Stern treats them like hot dog buns.
