Show HN: Start GPT threads in ChatGPT (& other sites) https://ift.tt/j4dbLFN
Show HN: Start GPT threads in ChatGPT (& other sites) I noticed current LLM chat apps don't support threads for follow questions, but instead they're one long conversation. Often when I'm digging into a topic and GPT responds with a book, I want to ask follow-ups in "side chats" that I'd prefer to be inline and in context rather than jumping to bottom of the page, so I created GPT threads. It's a chrome extension where you can highlight some text and start a chat focusing on that text and incorporating surroun…
Show HN: a Rust library for creating hierarchical state machines https://ift.tt/f3GRHML
Show HN: a Rust library for creating hierarchical state machines I've come to prefer modeling state machines with nested states, but implementing them by hand requires a large amount of error-prone boilerplate that obscures the important logic of the state machine. I found that the existing offerings in the Rust ecosystem - while inspiring - lacked a number of features that I was looking for, so I spent the last few months building moku. Feedback is welcome! https://ift.tt/y6Aj5qV March 1, 2025 at 02:30AM

I’ve written my fair share of papers in university and I’m a copy editor for our student paper as well. When fact checking, I noticed that Google often recommended unreliable scholarly sources(Medium articles, Reddit comments, and Linkedin posts) first.

Making Enforcement Fair: Our New Plan for the State Daylighting Law
Making Enforcement Fair: Our New Plan for the State Daylighting Law By Rebecca Ashton-Dziedzan The new state "daylighting" law will help make intersections safer. We're announcing a new plan to implement California's "daylighting" traffic safety law in San Francisco. The state law bans parking within 20 feet of the approach side of a crosswalk. This rule helps improve visibility at intersections for both people walking and driving. The law applies to both marked and unmarked crosswalks. Our goal is to make this ch…

Show HN: Ricotta – Language Learning to Replace Anki I’ve been tinkering with Ricotta for about a year now and I'm happy to announce it’s ready to for others to use officially. Largely the time has been spent making the project a framework to spin up newer projects quickly which I can share details around if anyone is interested. The app was born out of my frustration with Duolingo drilling me on words I knew. I moved on to creating custom Anki cards and found myself spending ages creating decks. It’s free, uses spaced repetition under the…
Show HN: Searchable Library of Free Audiobooks https://ift.tt/qefdtIj
Show HN: Searchable Library of Free Audiobooks I noticed that many websites offering free audiobooks tend to have clunky search functionality, making it harder to find what you're looking for. To address this, I’ve created a site that aggregates audiobooks from multiple platforms—complete with book reviews and ratings—making it easier to discover and explore new titles. At the moment, I've included audiobooks from popular sources like Librivox, Project Gutenberg, and Lit2Go. I'm open to suggestions on additional free audiobook sour…

Show HN: Stock Analysis Feels Broken – Here's My Take on Fixing It Stock analysis tools are powerful, but I’ve always run into three challenges: 1/ Too much data, hard to digest – Plenty of insights, but filtering what truly matters is time-consuming. 2/ No clear buy/sell decisions – You get the data, but figuring out what to do next is missing. 3/ No way to build a personal strategy – Most tools use preset metrics, but does not help to invest your own way. As a result, I often fall back on stock price and following others' opinions—no…

Show HN: Hyloblog – minimal, Git-based SSG for writing (not theming) Hi HN, We're working on Xr0 [0] and have been building a static-site generator that meets our tastes and needs. The basic emphasis is on simplicity and content rather than customisability and feature-richness. We are imitating Jekyll and Hugo (and other SSGs) in their basic generation paradigm and LaTeX in its separating form from content, but attempting to combine these into a unified, minimal philosophy where you can open a repo and start writing without needing a CLI t…

Around the same time, Patrick built Starwave (which is now ESPN Fantasy Sports) and later cofounded UrbanSpoon. We’re now building Gumshoe to help companies understand how AI talks about th…

Instead of using a fine-tuned version of o3, this method uses Firecrawl's extract + search with a reasoning model to deep research the web. The system is built using Vercel’s AI SDK for handling requests and streaming data, with an agent-based approach that manages search, extraction, and analysis. …

Many developers create great projects but lack the time or resources to maintain them. Instead of letting them fade away, why not sell them to someone who wants to continue the work?

Show HN: Modest – musical harmony library for Lua https://ift.tt/6dntJNF
Show HN: Modest – musical harmony library for Lua This is a project I've been building in my spare time over the past few months. It's a library that provides methods for working with musical harmony ‒ intervals, notes, chords. For example, it can parse almost any chord symbol (Fmaj7, CminMaj9, etc) and turn it into notes, or it can identify a chord from a given set of notes. I started this project with the idea of using formal grammar to parse chord symbols. I wanted to use it instead of a hand-written parser, which is the common appr…

What: A Val Town Project is a group of vals, files, and folders, versioned collectively. They support branches, forks, and merges. How: We made the sacrilegious decision to not build on git. We instead built…
