SQL Star
Leetcode of SQL on Android
What it does
Unlike LeetCode and similar platforms, SQL Star is built for practical, mobile-first SQL learning not just solving isolated problems. Practice real business scenarios, run SQL directly on your phone with a local SQLite playground, build custom tables, and learn from detailed solution breakdowns, thinking processes, common mistakes, and interview tips. It has a generous free tier works offline, requires no account, has no ads, and offers premium through a one-time purchase not a subscription.

Hey there! I’ve been working on DB Pilot for the last couple of months, and I recently added an AI assistant powered by GPT 3.5 to help you write SQL queries tailored to your DB schema. Simply ask what data you are looking for - GPT will figure out which tables to use, how to join them, and then write a query for you. The AI assistant knows which tables and columns exist in your database, meaning it can write queries specific to your schema. Besides that, it doesn't have access to any actual data from your database though, meaning your data doesn't get exposed to OpenAI.

Hey Hacker News! I wanted to share the open source project I have been working on during the last year: SQLPage, a tool to build small web applications entirely in SQL. Building web applications with just SQL isn't as crazy as it seems. Most simple applications can be expressed declaratively as just data queries that fill pre-defined web components. I'd love to hear your feedback and thoughts on it. Would you potentially use it? How can it be improved? Website: https://sql.ophir.dev/ Github: https://github.com/lovasoa/SQLpage Example app:…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
