Show HN: I built a browser-based image comparison tool for subtle differences

Hacker News - Thu, 02/26/2026 - 6:14pm

Hi HN,

I built this after getting frustrated trying to compare small differences in AI-generated images and game graphics settings. A lot of tools I tried either felt bloated or required uploading files somewhere.

So I made a simple image comparison tool that runs entirely in the browser. Everything stays local — no uploads.

It supports slider, split view, fade mode, pan & zoom, and a few other viewing options like grayscale and basic color frequency info to help spot subtle changes.

The goal was to keep it lightweight, precise, and easy to use.

Curious what you think.

Show HN: Free app to track countries you've travelled to

Hacker News - Thu, 02/26/2026 - 6:10pm

I know this already exists, but most such apps cost money or are freemium. I wanted to create a travel tracking app that was completely free, open-source and with a modern, playful design.

So I did that (with the help of Claude). The result is a iOS app written in Swift. You can track countries, major cities, and attractions you've visited or want to visit. You earn achievements as you travel to new destinations. There are also daily geography challenges.

The app is available on app store, and the code is on my Github (https://github.com/AnmolS99/voyage).

Feedback is very welcome :)

Brave New Smart Phone Dependence World and Google Support

Hacker News - Thu, 02/26/2026 - 6:08pm

tl;dr: I've spent countless hours with Google Support, but the support process has completely failed.

I was originally offered a mail-in repair (RMA) to my old address in Germany, but I've left that country and cannot receive the package there. Maybe I am the first digital nomad with Google products? I don't know... :(

Despite confirming my new location in Turkey, I was told by a supervisor that an Advance Exchange replacement cannot be shipped to me because the Pixel 10 was not launched in Turkey. But the supporter before told me to delete my payment profile from Germany. Now, what?!

Google does not offer a loaner device, meaning I am left without a necessary smartphone for critical functions (payments, travel, communication) while the device is sent for a 7+ day repair (if I could even send it in). The issue is just a small crack which made the fingerprint sensor unusable. Apple can repair such things on the spot in the whole world...

My health and livelihood are being severely impacted by the lack of a working phone and Google's inability to service a legally purchased, warranted device outside its country of purchase. I am not asking for a free upgrade but I need a working device and a resolution path that acknowledges I am a paying customer living in the modern, globalized world.

I need a Google employee or heavenly intervention after countless hours with the notoriously bad Google Support who can override the system to either:

Ship an Advance Exchange replacement to my current address in Turkey.

Arrange a direct, one-time repair or replacement from a German/EU service partner that accounts for my current Turkish location. No store in Turkey can repair the screen as nobody owns such a phone, here. I asked in 5+ stores in Istanbul, Ankara and now Izmir.

Please help get this in front of someone with the authority to resolve this logistics/policy deadlock. Thank you.

If not: can somebody in Turkey lend me a working current gen Pixel phone so I can at least survive in this brave new world? I am somewhat under the weather due to unemployment, lost home due to lacking money and now my last pierce of freedom, my smart phone, is broken for months and Google is letting me suffer. I wonder why but like Hiob in the Old Testament I will continue praying to the flying spaghetti monster as I cannot lose faith.

Thank you for reading.

A Phase-Ordered Pre-Geometric Projection Framework (Physics)

Hacker News - Thu, 02/26/2026 - 6:03pm

I’m an engineering leader in the tech industry, but my primary research focus outside of work is theoretical physics. I recently published an independent paper formulating a Phase-Ordered Pre-Geometric Projection (POPGP) framework. As the computational world hits the limits of discrete mathematics, I wanted to explore how continuous physical systems—specifically thermodynamic and continuous field equations—natively resolve spatial topologies and boundaries. I would love to get feedback from the physics and math communities here on the boundary conditions I used in the derivations. Happy to answer any questions or take brutal critique on the math. You can read the paper via the DOI here: https://zenodo.org/records/18728240

Show HN: InstallerStudio – Create MSI Installers Without InstallShield or WiX

Hacker News - Thu, 02/26/2026 - 5:25pm

I've been building Windows installer packages for 25 years. InstallShield costs $2,000+/year. WiX works but requires writing XML by hand and has a steep learning curve. Advanced Installer is better but still $500+/year.

So I built InstallerStudio — a WinUI 3/.NET 10 tool that generates production-ready MSI files with a modern UI. One-time license, $199.

It handles files, shortcuts, registry, custom actions, services, file associations, and installer branding. Self-contained — no WiX or other tools required under the hood.

The meta part: InstallerStudio builds its own installer. I used it to package itself for the first release.

Happy to answer questions about MSI internals, Windows Installer quirks, or why I built this instead of just wrapping WiX.
