Cooperation Cube (https://cooperationcube.com/) — A strategic 4-player memory/semi-cooperative board game I designed, played on a rotating 3D cube. Just added a daily puzzle (https://cooperationcube.com/daily) you can play without signing up. Place sticks, complete patterns, and try to beat the day's challenge.

Live Kaiwa (https://livekaiwa.com/) — A real-time Japanese conversation assistant. It listens, transcribes, translates, and suggests responses so you can follow along in conversations you'd otherwise get lost in. I built it because I live in Japan and needed something for the situations where missing a nuance actually matters — PTA meetings, bank appointments, neighborhood councils.


The landing page looks nice, but it’s very technical. It might be helpful to include some real-world use cases that show what people could do with the tool (at the 30,000 ft level).


Thank you for your advice, I will make it less technical and easier to understand. I appreciate your time taken to check it out.


I've been working on two small projects recently.

1. Live Kaiwa — real-time Japanese conversation support

I live in a rural farming neighborhood in Japan. Day-to-day Japanese is fine for me, but neighborhood meetings were a completely different level. Fast speech, local dialect, references to people and events from decades ago. I'd leave feeling like I understood maybe 5% of what happened.

So I built a tool for myself to help follow those conversations.

Live Kaiwa transcribes Japanese speech in real time and gives English translations, summaries, and suggested responses while the conversation is happening.

Some technical details:

* Browser microphone streams audio via WebRTC to a server with Kotoba Whisper * Multi-pass transcription: quick first pass, then higher-accuracy re-transcription that replaces earlier text * Each batch of transcript is sent to an LLM that generates translations, summary bullets, and response suggestions * Everything is streamed back to the UI live * Session data stays entirely in the browser — nothing stored server-side

2. Cooperation Cube — a board game that rotates the playing field

Years ago I built a physical board game where players place sticks into a wooden cube to complete patterns on the faces.

The twist: the cube rotates 90° every round, so patterns you're building suddenly become part of someone else's board. It creates a mix of strategy, memory, and semi-cooperative play.

I recently built a digital version.

Game mechanics:

* 4 players drafting cards and placing colored sticks on cube faces * The cube rotates every 4 actions * Players must remember what exists on other faces * Cooperation cards allow two players to coordinate for shared bonuses * Game ends when someone runs out of short sticks

Both projects mostly started as things I wanted to exist for myself. Curious what people think.


Oh that Live Kaiwa looks interesting, I might try it out this weekend with my wife and son (native Japanese). Anything to help my admittedly horrible Japanese


Shoot me an email (diasks2 at gmail.com) and I’ll whitelist your email for some free usage credits. Would love to get feedback.


Done :)



Yeah! We did that yesterday. It was a lot of fun: https://go-monkey.vercel.app/

It was what prompted him to ask about this game.


Thanks! Looking into this.

I found the apk file and I played around with Android Studio today but was having trouble getting the Nexus device with KittyKat or Lollipop to not crash when trying to open the device. Will keep trying different options.


Based Bluestacks


That would be great. Is there a way I can reach out to you by email for more info? (my email is my hn username at gmail)


Can you explain more what you mean by “do whatever you want without as much effort”? Is it because text-davinci-003 accepts more tokens for the prompt? Something else?


More a joke on the ease of getting good results without requiring (as many) prompt engineering tricks: https://help.openai.com/en/articles/6779149-how-do-text-davi...


I was trying to get davinci-003 to convert text to SQL, and it worked with a very simple prompt like "convert this text into SQL". With all their other models, I could get it to work too but all required a few examples within the prompt.

Nice work, this looks nice. I signed up and was writing a post. I was nearly finished and switched to the tutorial post (which I had archived). I clicked the hamburger and clicked "permanently delete" to remove the tutorial post. However, nothing happened. I then clicked on "All posts" to go back to the post I was working on and it had deleted that. Any way to recover that? I don't see a help email.


Yes, there's a chance I can recover this. Can you shoot me an email (hello@papyrus.dev) with the email you signed up with, and the name of the post you were working on? Happy to look into this.

This definitely sounds like a bug.
