dnh44··on Ask HN: Is Cursor deleting working code for you too or is it just me?
I've found 3.7-thinking to be much better for SwiftUI than 3.5. No random deletions, no hallucinations.

It does seem to be pretty keen on going a step further than prompted though but the code works well so I can't really complain about that.

dnh44··on Ask HN: Do your eyes bug you even though your prescription is "correct"?
You could also try Trivex instead of MR-8. Lens thickness should be similar but it has a higher ABBE value.
dnh44··on Ask HN: Do your eyes bug you even though your prescription is "correct"?
All the high index lens materials suffer from chromatic aberration.

The lens material you've now chosen actually has the best optical properties out of all the plastic lens materials. Its only downside is that the refractive index is only 1.5 which does mean they will be a little bit thicker than the high index ones.

You could also try a material called Trivex which also has low chromatic aberration while being a little thinner than the material you are using which is called CR-39

dnh44··on Show HN: Get Real-Time Alerts for Hacker News Mentions and Replies
Hi HN,

I built RemoraBuddy to make it easier to stay engaged on Hacker News without constantly refreshing the site. It helps you track mentions, follow users, and monitor replies to your comments—all from a lightweight macOS menubar app.

What it does:

* Mentions & Replies: Get notified when someone mentions you or replies to your comments.

* Follow Users: Keep tabs on specific users and their posts.

* Granular Notifications: Set up alerts based on specific keywords or accounts.

* Menubar Customization: Show or hide the menubar icon as you like.

The app is free to use for up to 3 keywords/accounts, with a modest one-time unlock fee for unlimited usage.

I’m planning to add a feature that highlights the most upvoted comments, creating a front page for top discussions instead of just stories.

Would love to hear your feedback or feature requests.

Thanks for checking it out!

dnh44··on Canon wants us to pay for using our own camera as a webcam
Your guess is correct. However I've not personally witnessed any nostalgia for communism in Romania though.
dnh44··on Canon wants us to pay for using our own camera as a webcam
I never said someone from the EU called, we think it was someone from the national government. Or it could just be someone from the newspaper who knows someone at the telecom company and they decided to have a laugh.
dnh44··on Canon wants us to pay for using our own camera as a webcam
Yes; former communist but not former soviet union. Old habits die hard I guess.
dnh44··on Is the world becoming uninsurable?
Given the choice between earthquake-proof and fire-proof I'd go with earthquake-proof every single time since you can't run from an earthquake.

Not 100% sure as they didn't introduce themselves but whoever called was able to get the phone number that the IP address was linked to and I assume both would have to have been involved in order to do that.

I have a family member of retirement age who got into the habit of anonymously expressing their love of the EU in the comments section of a local newspaper.

After a few months of this they received a phone call on their landline warning them that such public expressions are inappropriate and that there could be consequences should they not find a new hobby.

I too love the EU but I loved it much more 15 years ago.

dnh44··on Jack Elam and the Fly in 'Once Upon a Time in the West'
Oddly I remembered it as the fly escaping too but I've rewatched the scene now and he clearly lets the fly go.
dnh44··on React 19
I'm kind of the same with that. At some point quite a long time ago doing the front-end side of webdev became a chore for me so I stopped. I'm finding SwiftUI attractive because I feel like I make a decent frontend experience for free which allows me to focus on the functionality.
dnh44··on Ask HN: Open-Source SwiftUI Apps?
hackingwithswift.com is a pretty good resource to get you started.

I'm also looking at contributing to an open source SwiftUI app if I find one in the next week or so I'll post here again.

Hi is this web-tech or native?
dnh44··on Two Nobel Prize winners want to cancel their own CRISPR patents in Europe
In theory the patent is supposed to describe everything necessary to reproduce the invention. If something is left out that is critical then there isn't really any invention there and the patent shouldn't be awarded. I understand that in practice some patents are written in such a way to make this difficult.
dnh44··on Voyager 1 Breaks Its Silence with NASA via Radio Transmitter Not Used Since 1981
I never actually knew that. My mental model for how this works was way off; I'll have to read more.
dnh44··on Teach yourself to echolocate (2018)
I once lived in a shared 4 story house and I always intuitively knew where everyone in the house was, even if they weren't being loud. You could just tell where everyone was based on how the house creaked in response to footsteps. We had someone new move in once who walked very quietly and it made me feel slightly uneasy because they were sort of invisible to my hearing.
dnh44··on Two Nobel Prize winners want to cancel their own CRISPR patents in Europe
There are possibly also longer term repercussions from abolishing patents in that people or companies will naturally instead protect themselves via keeping trade secrets instead. This will probably result in some inventions being lost to history instead of being on the public record once the patent expires.
dnh44··on Bypassing regulatory locks, hacking AirPods and Faraday cages
That's a really awesome hack, thanks for sharing. I was slightly surprised that you had to go as far as spoofing a wifi network actually but it's great you figured it out.

Hi anhphong,

I've paid for a the pro account but even though the payment went through I can't access the pro templates

dnh44··on Rewrite it in Rails
I guess my post wasn't a critique of the blog post, it was a somewhat related story. I do actually agree with the blog post about not rewriting something that works. In my case it's a totally new project but it was my previous experience with Rails that made me not want to try it again for this particular project.

The API I'm working on is pretty simple and I want to finish it and forget about it so in my circumstances it seems that rust is a better choice.

dnh44··on Rewrite it in Rails
Over a decade ago when Rails was the shiny new thing I wrote an online ordering system that batched received orders then sent out orders to suppliers for whatever the customers ordered. It was easy enough to get the app setup and it didn't often need any new features but I remember really struggling to get it up to date and working with each new rails version. My memory is clouded by both time and my inexperience at the time but even though the app was "done" it never actually felt finished because I felt the need to continually update to the new version of rails just in case I did want to take advantage of of the new features in newer versions rails.

Anyway over 10 years later now and I find myself writing an API and my initial thinking was to return to rails but then I remembered the bad experience (which was probably my own fault I acknowledge).

Now I find myself writing this API in Rust because the ethos that an app can actually be done is attractive to me. It's taking me longer to write but hopefully I've made a good decision!

dnh44··on How to Deal with Loneliness as a Founder?
I’ve been in a similar situation and my company (20 employees) failed 3 months ago so I’ve had some time to reflect on things now. I had similar feelings to you at various points in the life of the company and it wasn’t pleasant.

What kept me going was to carve out some personal time for non-professional relationships. Since you say you can’t have these sorts of conversations with your current network of friends you should probably expand that network until you find people that you can be open with.

I moved in with my girlfriend and we built a really solid relationship.

I invested more time in friendships that I had neglected for a few years.

I also started playing a team sport which did wonders for me both physically and socially. If you’re not much of a sportsman try golf.

It takes a while to build those things though so in the meantime you might try seeing a therapist. Paying someone to listen while you vent out loud in a safe environment is actually helpful and will make you feel better. I never saw myself as the type of person who would go to a psychotherapist but now I feel that my preconceptions about that were totally wrong.

Also if you have the money for it consider getting a cleaner to free yourself of as many domestic chores as possible.

But definitely do something before the problem gets worse. Building your company is just one facet in building the life you want but if you ignore everything else you risk building a prison for yourself instead.

dnh44··on Ask HN: Performance regressions in SwiftUI apps on macOS Sequoia
As part of your yearly developer membership fee, Apple offer 3 incidents of code level support. This sounds like an appropriate situation where you'd want to use the service.

dnh44··on Remove PDF password protection using qpdf and AppleScript
FYI this still requires that you know the password to unlock the PDF to begin with so it won't help open PDFs that you are locked out of. If you were already using print->save-as-pdf to remove passwords from pdfs then I don't think this will give you much more functionality.
dnh44··on Show HN: SmokeScanner – Using cigarette price arbitrage to find free flights
The 200 cigarette limit is quite new. I believe that until recently there was no limit as long as it was for personal use.

Anyway I’ve never noticed anyone declaring their cigarettes at customs so I think it just one of those rules that never gets enforced.

dnh44··on DNA confirms there IS a big cat roaming the British countryside
My partner has had two (very) close up sightings and she said sightings among her peer group were common enough that no one thought it was that big a deal.

This was in the late 90’s though. There are certainly enough sheep and rabbits in the English countryside to support a small population of big cats.

dnh44··on DNA confirms there IS a big cat roaming the British countryside
My partner has seen them twice from close up (<10m), in the Cambridgeshire area. But this was in the late 90’s.
dnh44··on Ask HN: Is it polite to respond to colleagues using ChatGPT?
Well done. I finished the second paragraph before I realised. It the was the opening of the third paragraph ("In summary") that made it completely obvious to me.
