Show HN: Lengpal – simple video chat for language exchange Hi HN, I built a small tool called Lengpal. It’s basically a very simple video chat room made for language exchange. Most people I know who do language exchanges just use Zoom, Meet, or Teams. It works, but those tools aren’t really designed for it. One thing that always comes up is managing the speaking time so both people get equal practice. So the only thing we focused on for now is a built-in timer that lets you split the session between languages. For example 30 minutes Spanish, 30 minutes English. The idea is intentionally simple. You create a room, send the link to your partner, and start the session. No matching, no complicated setup. We just launched today and are trying to see if this simple approach actually helps people doing exchanges.

Show HN: Sway, a board game benchmark for quantum computing A popular philosophy in the HN community is that inventing problems to be solved by a technology is antithetical to the user experience. Much to the horror of some, I did just that to discover/invent this game. I started with the structure of quantum com putation and asked what kind of problem benefits from it. The answer was surprisingly narrow, but this was one of the results. Enjoy! https://ift.tt/SJzyHbh March 15, 2026 at 11:20PM

Show HN: Hedra – an open-world 3D game I wrote from scratch before LLMs With the current inflow of LLM aided software, I thought I would share a cool "hand-coded" project from the previous era (I wrote this in highschool so roughly ~8 years ago). Hedra is an open world 3d game written from scratch using only OpenGL and C#. It has quite a few cool features like infinite generation, skinned animated mesh rendering, post processing effects, etc. Originally the physics engine was also written from scratch but i swapped for the more reliable bulletphysics. https://ift.tt/J73dTEX March 14, 2026 at 10:35PM
