    A while ago I shared an early version of ggc, a Git helper I built in Go. Since then the project has grown quite a bit, and I’d love to share the latest updates (v6.0). Repo: https://github.com/bmf-san/ggc Install: - macOS/Linux: `brew install ggc` - Go: `go install github.com/bmf-san/ggc/v6@latest` - Homebrew: `brew install ggc` - Or grab binaries: https://github.com/bmf-san/ggc/releases Features: Dual modes: Traditional CLI commands (ggc add, etc.) and interactive mode (launch with just ggc) Intuitive command structure:…

    The idea is actually quite simple. As a Japanese learner and a coder, I've always wanted there to be an open-source, 100% free for learning Japanese, similar to Monkeytype in the typing community. Unfortunately, pretty much all language learning apps are closed-sourced and paid these days, and the ones that are free have unfortunately been abandoned. But of course, just creating yet another language learning app was not enough - there has to be a unique selling point. And then I thought to myself: why not make it crazy and do what no other language learning app ever did by adding a gazillion…

    Technologies used: Leaflet (frontend) Turf (Geojson generation and Voronoi generation) I noticed that my neighborhood is all Lawsons, so I got the location of all Conbinis and ran some basic analysis to see if these pockets of brand territory are common. I haven't worked much with web frontends before, so feedback is welcomed. I also have some ideas to maybe expand upon, like making the territory calculations based on streets and other geographical features rather than just beeline distance. The site isn't tested too much on mobile yet, but should be ok. Currently the frontend code and…

    Hey HN! I've built this bit of cuteware (software not solving a problem but just for fun) inspired from the patterns made by swipe typing on mobile devices. To me it seemed like the closest thing to an English version of Kanji and it would be cool to consistently recreate those patterns. The implementation is vanilla js to keep things simple (and from a bit of framework fatigue) I'm keen to see how people use qwanji. Any and all feedback welcome!

    Hi HN! I've found this visualization tool immensely helpful over the years for getting an intuition for how an LLM "sees" some piece of text, and with a bit of elbow grease decided to move all compute to client side so I could make it publicly available. I've found it particularly useful for - Understanding exactly how repetition and patterns affect a small LM's ability to predict correctly - Understanding different tokenization patterns and how it affects model output - Getting a general sense of how "hard" different prediction tasks are for GPT-style models Known problems (that I probably…

    Hello, guys~ I recently developed a data exploration and visualization app which can be used as a different type of open-source alternative to Tableau. It is extremely easy to embed in your apps just as a react component. The original purpose is to develop a lite plugin that can be easily embedded in most cases, it doesn't have to be a large BI, but a lite graphic plugin. GitHub: Kanaries/graphic-walker, https://github.com/Kanaries/graphic-walker The main features implemented: * A user-friendly drag-and-drop-based interaction for exploratory data analysis with…

    Hey Everybody! Hope you had a merry christmas Today I had a bit of fun with Claude. Started by scraping YC's startups list, then ran them through OpenAI's embedding service, then UMAP'd the embedding to reduce the dimension to just two coordinates and then just forced Claude to write React that would compile to visualize that. I had fun and I think it's interesting, so take a look! Also note that you won't be able to zoom on mobile (found about this Plotly limitation way too late). If there's interest I can fix this issue by changing plotting libs tomorrow :) Merry christmas

    Hi HN, I built https://rebrain.gg. It's a website which is intended to help you learn new things. I built it for two reasons: 1. To play around with different ways of interacting with a LLM. Instead of a standard chat conversation, the LLM returns question forms the user can directly interact with (and use to continue the conversation with the LLM). 2. Because I thought it would be cool to have a site dedicated to interactive educational content instead of purely consuming content (which I do too much). An example of a (useful-for-me) interactive conversation is:…
