It's almost depressing to me how much this post feels like a breath of fresh air if for nothing else than because it's clearly hand-written, not ghost-written by LLM.

No repetitive short sentences, no "Not X, just Y." patterns, and lots of opinionated statements, written confidently in the first person.

Please more of this.

epaga··on AI Usage Policy
I really like the phrase "bad AI drivers"...AI is a tool, and the stupid drive-by pull requests just mean you're being inconsiderate and unhelpful in your usage of the tool, similar to how "bad drivers" are a nightmare to encounter on a highway...so stop it or you'll end up on the dashcam subreddit of programming.

epaga··on System: Control your Mac from anywhere using natural language
(Not the OP, but...) have...have you tried Siri before? It is completely and totally ridiculous. Completely and utterly useless for anything other than setting a timer and turning HomeKit devices on or off (and even there it's entirely hit or miss).

Siri continues to be the most embarrassing Apple product on the market by a long shot.

epaga··on Ask HN: What Are You Working On? (December 2025)
Yep, implemented the canvas from scratch with SwiftUI, which is a lot of fun though it did have its share of "gotchas", especially in combo with SwiftData.

And thanks for the heads up about the cert expiration (just had expired yesterday), I renewed the cert now.

https://mindscopeapp.com - Mindscope 2 (iOS, iPadOS, macOS, watchOS)

Just submitted it to Apple for review this past weekend... basically Scapple's visual text canvas meets Workflowy's hierarchical focusing. I mainly wrote the app for myself to organize my thoughts. Very happy with how it has turned out.

Edit: Would be interested to hear why this was downvoted?

I actually made something quite similar to this with a few friends as an app 14 years ago using Wikipedia data. We called it LineTime, it was a fun little project! (Wow, I even found our video from back then...and man, that really was a LONG time ago https://www.youtube.com/watch?v=eW__WZ6pxJ8)

epaga··on When UPS charged me a $684 tariff on $355 of vintage computer parts
I live in Germany and UPS is asking for 116€ customs / fees for a personal gift package someone sent me worth $47 (40€ which is below the new 45€ de minimis line). Nearly everything in the blog post happened to me just this past week except I didn't have 116€ at home in cash(!) so they will be delivering on Monday (when I will have cash and then try to get it all back from UPS).

The whole thing is unbelievably infuriating and insane and I will warn anyone in the States to never again use UPS for shipping abroad.

Mindscope 2 : https://mindscopeapp.com (iOS / macOS)

A hierarchical text canvas for organizing thoughts and taking notes. I wrote v1 years ago and now spent about year rewriting it in SwiftUI and adding all my dream features like reminders, deep linking, and lots more. Currently in TestFlight beta, nearing release.

As the link shows, if you would put it on a t-shirt, you can absolutely expect to hear from Nintendo's lawyers, so the question will just be whether you have the time to put up a fight.
epaga··on Show HN: Mindscope 2 – visual and hierarchical thought organizer (iOS/macOS)
Hey HN - I'm John Goering - Java dev by day and indie app dev by night. :)

I've just started a public beta of Mindscope 2, a mind-mapping thought organizer app for iOS and macOS that’s been in my head for nearly 8 years, and I thought to celebrate, I'd post a Show HN.

The "spark" for this app came when I thought how cool a combination of Scapple's free-form layouting and Workflowy's focused hierarchy drilldown might be, especially if the primary goal was to keep things as simple, smooth, and fast as possible.

The first version of Mindscope was one of my earliest iOS apps, written in Objective-C. It worked well - MacStories reported positively on it - and it's been fun hearing from people over the years how much they've used it and love it, but as other projects grabbed my attention, it ended up on my back burner.

But for the last few years I’ve slowly been rebuilding it from scratch in SwiftUI, adding macOS and watchOS support, proper CloudKit sync, as well as features I had always wanted myself, like deep linking, reminders, long-form notes, OPML import and export, and lots more.

It’s a freemium app (all features included with 2 boards and 200 entries free) with a Pro subscription plan for unlimited notes and boards. During the beta, the Pro version is free, of course.

I would appreciate feedback or questions of any kind!

P.S. Here's the direct link to the TestFlight: https://testflight.apple.com/join/hKwsgjPX

epaga··on Glasses-free 3D using webcam head tracking
Interestingly, for this parallax 3D effect to work, the head tracking needs to basically move "backwards" from typical head tracking since it needs to keep the focal point the same, if I'm understanding correctly. Any time I've tried this out it's fun and would likely be most useful for something like a 3D painting you hang on your wall.

Related idea, but not the same, might be my iOS and Android app that uses your phone's AR for head tracking and then sends that data to your PC for smooth sim game head tracking. https://smoothtrack.app

epaga··on The scariest "user support" email I've received
I’ve always wondered why spam and scam emails have been so…dumb and obvious… 99.9% of the time.

It does seem like AI may change this and if even the tech savvier ones among us are able to be duped, then I’m getting worried for people like my parents or less tech savvy friends… we may be in for a scammy next few years.

The entire "no link" thing truly was outrageous from the start and, speaking as someone who very much admires Apple for many things, hearing that Schiller opposed the crazy 27% rule but was overruled by Cook truly makes me wonder whether Schiller wouldn't be a better CEO for Apple than Cook if these types of decisions are still being made.

epaga··on Gaming chat platform Discord in early talks with banks about public listing
Yes! We, too, happily used Discord for years in our small company - it was absolutely amazing and I also wonder why they don't have a version for companies - in my mind it easily beats Teams in nearly any factor that's important to us - though admittedly we're not a typical Microsoft-using enterprise.

(BTW we ended up writing our own tool instead and use that now => https://www.inetsoftware.de/products/cowork)

epaga··on Apple's Software Quality Crisis
Here's what I find most puzzling about these things: Apple does amazingly helpful WWDC sessions on how to profile and improve your code, how to prioritize performance...but when it comes to their own apps, it's like they forget everything they know?

Messages on Mac is one of my biggest annoyances. How do you make one of the most used messaging tools and have the keyboard lag so badly while typing - sometimes even skipping typed letters? It's a complete mystery to me.

epaga··on How X-Plane Works
FS2020 has some simple tutorial missions for taking off, landing, etc. Other than that there are loads of great YouTube channels such as Squirrel that walk you through things https://www.youtube.com/playlist?list=PLbphwhPw2JuvwwsD-H3xo...

As for hardware, I'd recommend at minimum a joystick of some kind if you don't have one.

And finally I'd give you a shameless plug for my app SmoothTrack which lets you fluidly control the game camera with small head movements - https://smoothtrack.app ;-)

Looks like Austin found an editor to clean up his texts which otherwise end up super nerdy and way too long. This is excellent, readable, and punchy. Makes me consider getting X-Plane 12 even though I already have 11 (and MSFS 2020 and 2024).
