Show HN: Browser-based Glider Sim

Hacker News - Mon, 05/25/2026 - 1:39pm

I've flown gliders a little but never had a reason to get into the underlying aerodynamics. This sim put together as a learning experience, using an ancient pamphlet on gliding paired with a few evenings of LLM time.

The sim: - Controls with stick, ailerons, elevator, rudder, and airbrakes — W/S pitch, A/D roll, Q/E yaw, B airbrake - Attempts to accurately model angle of attack via interaction of wing and air movement to give lift/drag - Built on a real glider's numbers. Loosely modelled on an ASK‑21-class trainer: ~33:1 glide ratio, ~0.6 m/s minimum sink - To stay aloft, you hunt for lift — thermals rising off sun-warmed ground + ridge lift where wind is deflected up terrain, etc.

Glider pilots: tell me where the behaviour feels inaccurate.

S there room for a VPN with zero Five Eyes servers and RAM-only infrastructure?

Hacker News - Mon, 05/25/2026 - 1:38pm

I've been building on AWS for years and got deep into privacy/networking recently. The more I learned, the more I realized most VPN providers are theatre.

The problem I see: "no-logs" is meaningless if your servers are physically in the US, UK, Canada or Australia. A warrant is a warrant. Even providers I respect like Mullvad and Proton have servers in Five Eyes countries.

What I'm thinking: - Servers only in Iceland, Switzerland, Luxembourg, Romania, Japan - RAM-only — no disk, no logs possible by design, reboot wipes everything - WireGuard - Open source, annual Cure53 audit - BTC/Monero, no account required

Break even is around 200-300 customers. Infrastructure to start is maybe $500-1000/month.

Honest question: does Mullvad already own this positioning well enough that there's no room? Or is "zero Five Eyes + provably no logs" a real differentiator for a specific segment?

Also curious if anyone has experience running infrastructure businesses in Iceland or Luxembourg specifically.

Show HN: A web to see nearby TFL trains

Hacker News - Mon, 05/25/2026 - 1:37pm

This was mostly vibe coded over the bank holiday but the funny thing is that it was derived from an existing stale iOS swift project I started and never finished nor shipped that was built by hand, over the length of multiple months. It's just a ui that asks for your location and shows platform arrivals on your closer tube and overground stations using tfl api. Learned a lot about the setting up of stuff and all my api modelling and schemas hopefully went into shaping this. But it's quite impressive that now any feature can be built and deployed within seconds by claude remotely.
