#842I'm working on a Unicode visualization tool [note 1]. It's meant to visualize transformations and relationships between characters, as well as connect everything directly to the exact lines in the Unicode Character Database (UCD), which defines these relationships. The UCD is a series of text files, it also has an XML version.
I love online Unicode tools, serious ones and silly ones, and I use them often for fun or for development. What I see online is that few technical people have a good understanding of Unicode, or have big misconceptions about how it works. I'd like to change that, through visualizations and direct links to the data sources (the aforementioned UCD) and links to the Unicode documentation (which is well-written but can be difficult to navigate or even find).
I've worked a lot on it, but I'm totally stuck again. I get too zoomed in and it's hard to see the big picture, plus it's difficult to know how much effort I can realistically put in because I don't know how big the market is. It's a niche tool, but how niche? Would anyone pay for it? But I'm not sure how to do market research, especially for a niche like this. Any advice would be appreciated!
1. The initial idea was based on this post I made in 2024: https://news.ycombinator.com/item?id=42014045

My twins (in high school) and I are building an AI study buddy.The idea is simple. A peer-level “study friend” you can work alongside, ask questions, and stay on track with.
It’s not doing anything ChatGPT or Claude couldn’t do. The goal is packaging it into something that feels a high-schooler would actually want to use when they’re studying.
We are also using this as a weekly project to learn the abstract stuff. Product thinking, design, pricing, marketing, and how to turn a vague idea into something real. Each week the kids prioritize a feature, research it, write up the idea, and then we build (or cut) it together.
Our stack is Claude Code, TypeScript, React and it's hosted on Cloudflare Pages for frontend + Workers for API.
No login or credit card required to try this out. We welcome your feedback.

#844I'm trying to build a native postman alternative using Rust + Iced. I want it to use .http files as its collections and .env files as its environments. So that data is stored in plain text and easily editable by AI and usable by other apps like VSCode rest client.

#847A typed execution graph for Go. You write functions with typed inputs and outputs—Docket infers the dependency graph, runs independent steps in parallel, and caches what you tell it to. It integrates with River and a number of data stores.
I spent a year attempting to adopt Temporal at scale, and 6 months trying to wrangle some multistep data enrichment and ML pipelines. This is what I wish I'd had with what I learned

#848I shared this last month, but I’m still having a lot of fun working on it. I made a daily word puzzle called Tiled Words. https://tiledwords.com Currently about 2,000 people play every day and I’ve released 59 puzzles! One feature I’m excited about is crowdsourcing puzzles. Today’s puzzle is a “community puzzle” made entirely from clues that players submitted! I plan to do this every week or two. I wrote about launch…
Really fun!

#849https://mytinycafe.com/ An PWA primarily for my wife and my daughter. They can order their hot chocolate and their coffee as if they were going to grab something at a fancy café downtown, but instead it's at home and I'm the barista. It is quite nice to have for when my wife comes back from work and want something specific, or when we are waiting for the visit of a few friend, they can order exactly the available bev…
So cozy. I love this.
One nit: the contrast in dark mode at least on the marketing site is a bit off (But I'd love to fix it myself if it was open source :) )

Bug report: I tried to create a new cafe with a name that contained a space character in it. The form told me the ID was invalid but seems to have created my user account anyway. When I log in now, the CafeID I get is 'undefined'; as in, I am now the proud owner of https://mytinycafe.com/undefined/barista. I'm assuming this is not intended :)
