Just read today's story on FounderFiles – didn't expect that ending

Wed, 04/30/2025 - 11:48pm

He was only 21 when he and his friends launched Diaspora — a decentralized Facebook alternative.

They raised $200K on Kickstarter. Even Zuckerberg donated. A year later, Ilya died at 22.

The story honestly shook me. I had never heard it before. Worth a read: https://founderfiles.dev/story/11

Anyone remember this story when it happened?

Show HN: Got laid off. Got sick of ghost jobs. Built something

Wed, 04/30/2025 - 11:25pm

Hello everyone,

I got laid off last year and during the job hunt, I kept running into ghost jobs, these listings that never lead anywhere. Super frustrating.

After some point, I started tracking company behavior across job boards. It snowballed into a little web app where you can actually see how companies are hiring — or pretending to.

It's free, early stage, UI is a bit rough, but here’s what some info it shows per company: -Job boards they post on -ATS system they use -Median salary by role -Post frequency + how old the listings are -Skills and degree requirements -Track all existing postings major job boards

Right now it’s showing Fortune 100 daily. Adding 2,500+ companies next week. Long-term goal? provide access to our database that actually track over 1 millions companies, I'd rather wait before provide access to all these data du to high cost of maintenance and resource required.

It also enable anonymous report from any jobs seekers toward any companies. Their is also a dedicated public page per company providing space to speak and have discussions.

If this helps someone out there avoid wasted time, it was worth building.

Here it is: app.ghostjobs.io

Happy to answer questions or hear thoughts, you feedback help!

Show HN: MintFlow NetStack – A new WireGuard iOS client built upon fd.io VPP

Wed, 04/30/2025 - 11:16pm

Hi HN,

I just got MintFlow NetStack 1.1.0 approved by Apple, which introduces app-level routing capabilities. I thought this would be a good time to share the project and some of the technical background behind its development.

Over the past two years, I’ve built two iOS VPN apps based on Tailscale. I appreciate their excellent documentation and high-quality code. However, I wanted more flexibility on the client side—particularly around local routing and split tunneling. While Tailscale now offers an App Connector feature, my use case required everything to run locally, without needing a central coordinator to distribute DNS routes.

Since I’ve been working with fd.io VPP for a while and really like its architecture, I decided to try building a WireGuard-based VPN app on top of it. VPP has a WireGuard plugin modeled after FreeBSD’s implementation (though not actively maintained). My first challenge was porting the VPP core to Darwin (the underlying OS for iOS/macOS). Thanks to recent FreeBSD support via epoll-shim, it turned out to be complex but feasible—and I eventually got VPP running on macOS.

From there, I bridged Apple’s utun interface with VPP’s host stack, handling BSD socket I/O and eventually getting a working app. Version 1.0.0 shipped with basic split tunneling based on CIDR prefixes, but that felt too limited.

So last month, I added an internal stub DNS resolver using hickory-dns (Rust-based), and enabled VPP's host stack to reconstruct TCP/UDP connections from the Apple tunnel interface and forward them via local interfaces (Wi-Fi/Cellular). This unlocks much more granular routing—like selectively sending specific traffic through WireGuard, keeping others local, or blocking routes entirely using VPP’s blackhole.

I'm happy to discuss the technical details. Never thought I’d still be writing C in 2025 for an iOS app core—though Rust is now part of the stack too. I initially tried using c-ares for DNS but opted for Rust to move faster and learn something new.

It’s been a lot of fun building this. Right now, MintFlow is a paid app with a one-time purchase. I plan to keep expanding it—VPP’s active development means I can add features like MITM-based HTTPS capture and more advanced routing in future releases.

Show HN: Using AI to test the beauty for you

Wed, 04/30/2025 - 11:11pm

After failing about 20+ products, I built another product in 2-3 days! Hope it's not too bad! This time it is for the people to take a test for their beauty. And it will give you a beauty test score. Not very serious, but maybe a little interesting! Have a try, and give me some feedback!! Why do I make this product? As a lady, sometimes I am not sure about my facial beauty, and we all know the snow-white princess and her stepmother's story. I wish there's a product that can give people confidence and also give some fun!
