PubKey – Communicate Privately in Anonymous Public Spaces
A little while back I remember seeing a user on a certain anonymous imageboard asking for an invite to a selective email host. Only after a few minutes did the guy realize the perplexity of the situation. How do you insure against a race condition in a public forum with no way to direct message? Luckily, he nabbed the invite code, but it got me thinking about using PGP to provide a solution. This is meant to be a rough PoC and the UX is definitely not ready for the average Joe, but the functionality I'd like to think is there. What catbox.moe is to dropbox is what I'd like this to eventually…
In plain words
PubKey is a tool for sending encrypted messages in anonymous public spaces without direct messaging capability. It uses PGP encryption to allow users to securely communicate and share information like invite codes on forums where recipients cannot be contacted directly. The tool is positioned as a minimal proof-of-concept with basic functionality, intended for technical users willing to work with PGP workflows. Source code is available on Codeberg.

Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So…
