Show HN: I made a simple, open source, chromatic tuner mobile app I'm a musician by night, software developer by day, and one of the minor frustrations I've always had was trying to find a simple tuner app for my phone. Looking at both the iOS and Android app stores, you'll find a lot of the top tuner apps are rather bloated with ads or subscription callouts. I thought I'd create a dead-simple minimalistic mobile chromatic tuner the way I would like it - open the app and tune my guitar. My work is in web with NodeJS and React, so I chose React Native since it was the easiest to understand coming from React. Flutter was also an option since the company I work for has a team working in that, but I thought it would be a bit too much effort to learn Dart. I learned a bit more about React rendering with this project as well. The main issue I had was trying to have a React state variable be constantly updated with any frequencies detected from the mic input, but that ended up...

Show HN: lambdaprompt – build, compose and call templated LLM prompts For the past few months I've been building a lot of things with LLMs (GPT-3, Codex, etc.) as I've been trying to push them to their limits (especially towards applying them to the tabular data domain) When working on this, I've found there are some common patterns for solving problems (templating, chaining, functional-programming style operations, etc.) As I've iterated, I've come to believe that a functional style interface is likely going to power a new wave of systems I'm calling "prompt-machines"(systems where the core new unit of work is a "named" LLM prompt, extending the "function" concept). Additionally, in order to make the code capable of meta-prompting (where the LLM can write its own templated prompts), I aimed to make the interface and library as simple and lightweight as possible. I think I've achieved my goal, so I'm releasing the library to...
