Show HN: Luna Rail – Treating night trains as a spatial optimization problem (❄️ Score: 150+ in 1 week)
Link: https://readhacker.news/s/6wiPS
Comments: https://readhacker.news/c/6wiPS
Hi HN, I'm Anton, founder of Luna Rail.
I've always thought night trains are a fantastic, sustainable alternative to short-haul flights, but they're often held back by a lack of privacy, comfort, and poor economics due to low passenger capacity.
I became overly fascinated with this puzzle. I view it as a kind of night train Tetris (my wife less charitably calls it "sardinology"). I spent way too much time learning about and sketching various layouts, trying to figure out how to fit the maximum number of private cabins into a standard railcar, while making them attractive for both day and night travel.
This eventually led to a physical workshop (in Berlin) and a hands-on rapid prototyping process. We've built a series of full-scale mockups, starting with wood and cardboard and progressing to high-fidelity versions with 3D-printed and CNC-milled parts, with various functional elements.
Hundreds of people have come in to test our various iterations, because you can't test ergonomics or comfort by looking at renderings (although we did create a bunch of nice ones).
The link goes to our home page showing our approach and some of the thinking behind them. It’s been a lot of fun working on this puzzle, and we're excited to share what we've come up with. We hope you think it's cool too and would love to hear your thoughts.

Show HN: Scream to Unlock – Blocks social media until you scream “I'm a loser” (Score: 151+ in 6 hours)
Link: https://readhacker.news/c/6wGsj
Hi all,
I kept wasting time on social media, even though I’d promised myself I’d stay focused. Regular site blockers didn’t help.
I needed something that felt annoying enough to break the habit. That’s how the idea came up: make the blocker ask me to say something embarrassing out loud before it lets me back in. If I actually have to yell “I’m a loser” into my mic. Even better - the louder I screamed, the more time I’d get.
So I put together Scream to Unlock. It’s silly, but so far it’s done its job. My social feeds stay locked unless I really want them.
