New NetNewsWire Crash in iOS 27 Has Made Me a Bit Salty

I returned from a lovely summer vacation (family, beach) to find that iOS 27 beta has fucked up the transition between split view and compact — I’ve got a boatload of crashes, mostly on Pro Max devices and a few on iPad. Here’s a representative crash log. The feedback in Te...

NetNewsWire Status

It’s been a year since I retired — my last working day was June 6, 2025 — and I like being able to say that I’ve spent the year adding nothing, not one penny, to shareholder value. 🌴 * * * My hope for retirement was to get a lot of work done on NetNewsWire. A year ago it ...

Seattle Xcoders Presentation by Justin Miller Tonight

I’m psyched for @incanus Justin Miller’s presentation tonight at Xcoders on “Swift Result Builders Case Study: Parsing.” I like writing parsers, and I’m very curious about Swift result builders. Should be a good one!

See this post on the Xcoders blog for more details about the talk and for when and where to be.

I Tried to Explain What I Do

I’ve known for decades that most of family and friends (except for family and friends in tech) have no idea what I do — they just think it’s math-heavy and mysterious.

Well. It’s definitely not math-heavy and it shouldn’t be mysterious. So I figured I’d write up What I Do.

Even if I never actually send this page around to everybody — because that would actually be kind of weird, like giving them homework to understand me, me who suddenly (suddenly?) seems like a complete narcissist — it was a good exercise for me to do anyway. Especially the part about explaining why I write NetNewsWire.

Seattle Xcoders Talks This Week Considered Unmissable

The title is a little over the top, but barely — we have two fantastic talks this Thursday (March 5) that you should go to. (I’ll be there!) Laura Savino will present “Learn Out Loud”: As devs today, we’re supposed to demonstrate immediate skills in tools whose confi...

Why Objective-C

In my previous post I talk about how I got rid of hundreds of thousands of lines of Objective-C code while at Audible and I explain why keeping Objective-C code around is a terrible idea. And I explain that… I’m not stuck in the old ways; I’m not the guy insisting on the s...

Why Not Objective-C

At my last job, at Audible (hi Audible folks, if you’re reading this!), I led the effort to port our remaining Objective-C to Swift. When I started that project, Objective-C was about 25% of the code; when I retired it was in the low single digits (and has gone even lower si...

Blog Fuckup

I’ve been working on my blog software (a static site generator) and managed to screw things up enough that random old posts got published on the site and in the RSS feed.

As soon as I saw the issue I fixed it, but I’ve been getting email from folks about some of the posts, so I know they got picked up by some RSS readers.

Those posts are ancient! Sorry for the confusion.

Email from Family in Minnesota

Our family in Minnesota knows that we all worry about them, and so yesterday they sent an email to everyone. This is surely one of many thousands like it. Maybe you’ve written one of these. Maybe you will write one of these in the future. All of the below is the email fr...

NetNewsWire 6.2: RSS Plus Markdown

On the NetNewsWire blog I’ve just announced NetNewsWire 6.2 for Mac and iOS.

This release is almost entirely bug fixes — but it does add a couple small features and one potentially interesting one: it now supports Markdown in RSS (via the source:markdown element). Read all about it on the NetNewsWire blog.

(And now we’re working on NetNewsWire 7, which will adopt the new Liquid Glass UI.)

Why NetNewsWire Is Not a Web App

Tim Bray writes, on Mastodon, I think correctly: The canceling of ICEBlock is more evidence, were any needed, that the Web is the platform of the future, the only platform without a controlling vendor. Anything controversial should be available through a pure browser ...

Writing Mac and iOS Apps Shouldn’t Be So Difficult

In the ’90s and early 2000s I worked for UserLand Software — Dave Winer was founder and CEO — on a Mac app called UserLand Frontier. The app was a scripting system and hash-table-oriented database that powered the early blogging and podcasting worlds. (That sounds grand, ...

Tough Season in the Apple Fields

We’re adopting Liquid Glass for NetNewsWire 7, which we’ll release some time after the new versions of macOS and iOS come out. Stuart Breckenridge has been doing great work on getting this done — and he’s written up a couple blog posts (with screenshots!) on his prog...

Breakpoints Show Thursday in Seattle

James Dempsey and the Breakpoints will be appearing in a Breakpoints Jam this Thursday (Aug. 21) at Bale Breaker in Ballard. Free show! Awesome songs!

The event starts at 6 pm and music will start around 7 pm. I’ll be on guitar — and you can expect local superstars Ken Case (keyboard, vocals) and Laura Savino (vocals) plus a special mystery guest or two from out of town.

The show will be mostly acoustic, and it will be outside at the picnic tables. I hope to see you there!

Tomorrow is No Kings. There’s one near you!

Chatting with my friends about how I hate these fascist assholes doesn’t do a damn thing. Protests work. (Imperfectly, sure, with no guarantees. But it sure beats not protesting.)

Retirement Day

I wrote in my love letter to my colleagues at Audible that retirement is coming up — and now it’s here. Today’s the day! I’ve attended my last meetings. I’ve said my goodbyes. My laptop’s ready to ship back to Audible HQ. * * * I started working in 1984, while in h...

Retirement and NetNewsWire

To answer some questions people have asked me about my impending retirement… What does it mean for NetNewsWire? Good things! I’m not retiring from writing apps — which means I’ll have a lot more time for working on NetNewsWire. It’s been 15 years since the last tim...

My Wildly Incorrect Bias About Corporate Engineers

Before I went to work for Audible (five years ago now — time flies!) I had a bias about engineers that worked for large corporations. I assumed that they weren’t as good as indies and engineers at small companies, or else they’d actually be indies or work at small sho...

Harris for President

Donald Trump is a gross villain and a traitor to our country. He’s a convicted felon, adjudicated rapist, and head of a criminal organization; he works with criminals and he pardons criminals; he’s a narcissist and violent insurrectionist, racist and misogynist; he’s the mas...

NetNewsWire and Conditional GET Issues

Reruns

It’s not a bug in your RSS reader if recent articles in this feed all suddenly appeared as unread. You may even have seeming duplicates.

Sorry about that! It’s due to my changing settings in my blog generator. Pages now have a .html suffix where before they had none. This change impacts permalinks, which also changes the guids in my RSS feed — and NetNewsWire and other RSS readers use the guid property to identify articles, which means these will show up as new articles.

(Note: I’ve created redirects so that old links pointing in will still work.)

Why NetNewsWire Isn’t Available for Vision Pro

I’ve been getting questions about NetNewsWire’s unavailability on Vision Pro. Why isn’t it there? When might it be there? Here’s the scoop: I consider it risky to support an app running on a device I don’t own. Imagine writing a Mac or iPhone app and not actually running i...
