agjmills: Trove - a really simple web app where I can shove some files without having to really think about configuring anythinghttps://agjmills.github.io/trove/Go, docker, bit of alpine js

siddboots: I’ve been building a toy for exploring elliptic functions, modular forms, and elliptic curves. Sorry mobile support is not there yet.https://grge.github.io/weierstrass/

rpjt: I've got a mobile app.It allows you to get a wake up call from someone friendly, somewhere out there in the world.It's got a handful of regular users and it's mostly me making the calls, but it's great fun to wake people up!No phone number required - these are VoIP calls via the app.Built it because I think it's cool.

victorbjorklund: That is such a wholesome and fun idea (but probably gonna be abused if more users). Link?

embedding-shape: From another submission (https://news.ycombinator.com/item?id=47738827), there was a screenshot of Google Docs/Drive showing a popup saying "You cannot do copy/cut/paste with the mouse" whenever you try to right-click and copy.Some months ago, I saw that very popup, and finally started working on something I've been wanted to do for a long-time, a spreadsheet application. It's cross-platform (looks and work identical across Windows, macOS and Linux), lightweight, and does what a spreadsheet application should be able to do, in the way you expect it, forever. As an extra benefit, I can finally open some spreadsheets that grown out of control (+100MB and growing) without having to go and make a cup of coffee while the spreadsheet loads.I don't really have any concrete to share, I guess it'll be a Show HN eventually, but I thought it was funny it was brought up in a similar way in that article as was the motivation for me to build yet another spreadsheet application.

ojdon: https://newfeed.ioTurns your project's GitHub release notes into user changelog that your users actually want to read.

kilroy123: I made a thing to watch YouTube like it's 2000s cable tv.I'm working to make it better right now.https://channelsurfer.tv/

sleno: I'm building a debate/writing game platform: https:argyu.funThe mission is to incentivize better thinking. For each game there's an AI judge that scores everyone's answer based on a public rubric (style, cohesion, logic, etc).Currently uses fake money and ELO score but thought it could be a very interesting competitive game for real stakes.Any feedback is much appreciated.

junaid_97: I'm building free immigration software for DIY applicants [1]It's a free USCIS form-filling web-app(no Adobe required). USCIS forms still use XFA PDFs, which don’t let you edit in most browsers. Even with Adobe, fields break, and getting the signature is hard.So I converted the PDF form into modern, browser-friendly web forms - and kept every field 1:1 with the original. You fill the form, submit it, and get the official USCIS PDF filled.I found out SimpleCitizen(YC S16) offers a DIY plan for $529 [2]So, a free (and local-only) version might be a good alternative[1] https://fillvisa.com/demo[2] https://www.simplecitizen.com/pricing/

williamcotton: Space Trader!Imagine mixing Magic: The Gathering, StarCraft and Civilization’s hex grid combat.There’s multiplayer but I haven’t put the server anywhere yet.Check out the introduction here:https://github.com/williamcotton/space-trader/blob/main/docs...Clone the repo: npm install npm run dev There’s maybe a couple of other games called Space Trader so if anyone has any suggestions for a new name, I’m all ears!

ryanchants: An app for supplementing learning in my masters program [1]. I'm currently in enrolled in the MCS Online from UIUC. My first course, Natural Language Processing, has been interesting, but it's a coursera-based course. This means the lectures are pre-recorded and mostly just the professor reading the slides. It's hard for me to stay engaged and really learn the material. So I started with a series of claude prompts that took the lecture slides and created a pre-watch summary, and then helped me drill the concepts after each lecture. I think converted those into a platform where I can upload notes/lecture slides and have it generate quizzes. It starts with recognition(multiple choice) questions, and eventually moves to recall(short answer) once you prove mastery of a topic. It also generates flashcards from failed answers. It extracts topics from the uploaded materials, and tracks mastery over time. Mastery rots if you don't touch the platform/topic for a while.I'm not sure if I'll every productize it in any way, but I could see a world where it's used by people prepping for the bar, med boards, various continuing education stuff. Right now it's just a fun platform to build on as I explore the current wave of technologies. Building a framework for evaluating different LLMs for best price/accuracy. Adding a RAG pipeline so wrong answers can point back to source material for further review, etc.I'm looking at moving from backend engineering to a more MLE or agent pipeline role, so this is giving me something more than school projects to build on. While also helping me do better at school.[1] https://studyengine.app/

spudlyo: I'm writing an essay about how I use an ancient text editor, GNU Emacs, along with gptel, Gemini, some local models, yt-dlp, and patreon-dl to help me me study an ancient language, Latin.I want to show how I liberate poorly aligned, pixelated PDF image scans of century-old Latin textbooks from the Internet Archive and transform them into glorious Org mode documents while preserving important typographic details, nicely formatted tables, and some semantic document metadata. I also want to demonstrate how I use a high-performance XML database engine to quickly perform Latin-to-English lookups against an XML-TEI formatted edition of the 19th century Lewis & Short dictionary.I intend demonstrate how I built a transcription pipeline in Emacs Lisp using tools such as yt-dlp and patreon-dl to grab Latin-language audio content from the Internet, transcode the audio with ffmpeg, do Voice Activity Detection and chunking in Python with Silero, load the chunks into Gemini's context window, and send it off for transcription and macronization, gather forced-alignment data using local a local wav2vec2-latin model, and finally add word-level linguistic analysis (POS, morphology, lemmas) using a local Stanza model trained on the Classical corpus.This all gets saved to an an XML file which is loaded into BaseX along with some metadata. I'll then demonstrate some Emacs Lisp code which pulls it into an Org-mode based transcription buffer and minor-mode for reading and study, where I can play audio of any given Latin word, sentence, or paragraph, thanks to the forced-alignment and linguistic analysis data being stored in hidden text properties when the data was fetched from the database.Lastly, I'd like to explore how to leverage these tools to automatically create flash cards with audio cues in Org mode using the anki-editor Emacs minor mode for sentence mining.

f3408fh: I built a MacOS-native app [1] to control Positive Grid Spark amps [2], without needing a phone.Official app is mobile-only and clunky, and the workflow is awkward if you're sitting at a desk. Hardest part has been maintaining compatibility across model. Small protocol changes or optimizations I make for one amp can break another. That means I have to do a lot of manual testing before every release. So I'm trying to think of an emulation layer or test harness I can build to make my life easier. Happy to hear suggestions there.About ~50 people are using it so far, and main feedback has been that it's much faster and more reliable than the official app.[1] https://tonepilot.app [2] https://www.positivegrid.com/products/spark-2

epiccoleman: I've got a couple of different things going as per usual, but the one that I'm currently most excited about is Lotus Eater:https://lotuseater.epiccoleman.com/It's a mostly vibe-coded fan site for jamtronica greats Lotus. I wrote/prompted a scraper to pull in setlist data from Nugs and have been having a lot of fun coming up with cool data analysis stuff to do with their sets.I've seen them 7 times (chump change compared to some fans) and was starting to get certain intuitions about like, "if I hear song X that probably means they won't play song Y." For example, one of my favorite Lotus tunes, It's All Clear To Me Now, seems to fulfill a similar "function" as another song - Did Fatt.It was pretty cool to see that intuition bear out in the data (they've only ever been played in the same show one time in over 900 total shows).I've got a bunch of other "data" features sitting in a PR in my Gitlab, need to get around to reviewing and testing it so I can push out the next update. Also have a few other ideas for it, although I think there's probably a point coming fairly soon where there's not really anything left to do.I posted it on the main Lotus fan group on Facebook. I have a grand total 8 users. I love those users.The site is nothing crazy, it will never make money or anything - but it's just been a ton of fun to have something cool to hack around on.

wewewedxfgdf: 4X games are very popular on Steam.A little bit like Neptune's Pride perhaps?

netdur: I am working on hugind, I have two goals:- make it reliable to run LLM inference on company hardware, even when it is poor or outdated- bring chaotic agentic behavior under control in business contextshttps://github.com/netdur/hugind

goqu: A web app that allows to practice speaking another language by participating in pre made scenarios, so beginners don’t get stuck.https://fluenly.ai/

wewewedxfgdf: Just built a system to allow my son - who is in final year high school - to do exam questions from previous years - the government publishes 20 years of historical exams so I made a system to parse out the questions and answers. the student can answer them then they can submit their answer for marking by the AI/LLM.

AshesOfOwls: I'm working on https://react.tvIt lets you create TV channels from digital media such as YouTube, The Internet Archive, TikTok, Twitch, and Dailymotion. It does that by letting you schedule videos against a custom calendar system.Since filling out even a month of content can be a lot of work, I built some things to make the process easier.* Advanced scheduler to know when and how long content can be played at any given datetime* Real time team collaboration* Channel libraries to organize media* "Blocks" - Create a dynamic schedule which generate hours of content that mimics real television scheduling. It even carries over your playback history between generations so that playlists continue from where they left off.* A catalog to find media from official sources on YouTube* Embeddable as an OBS browser source to restream your owned content* Repeat content infinitely or temporarily to create 24/7 channels.If all goes well I am hoping to re-release sometime this month.

contraposit: https://en.wikipedia.org/wiki/SuperformulaHave you heard of Superformula ? I remember playing with them few years ago.

ekrapivin: I've spent several years developing an ad-free website with a few dozen solitaire/puzzle games:https://inSolitaire.comI am currently rewriting+testing the engine and about to add ~400 games to my platform in a few weeks.

paulorlando: I'm researching Luddite-style examples from around the world. That is, examples of when people rebel against new technology that they see as harming their livelihoods.

qualityslop: Building a map and text-based mobile game where you walk around and graffiti tag things (like Pokemon Go, except you are not looking at a map on your screen). The interface is text room names + descriptions, like an old school MUD, that update as you walk in different directions. They rooms are based partly on what is there in real life, although known points of interest are changed to fit a 'cyberpunk' theme.The app is built in React Native (almost entirely with AI although I'm fairly particular about some of the features and methods it uses) with a Go backend. Map data comes from PMTiles.

marcusdev: I'm working on a fully offline, client-side train journey planner for UK rail - https://railraptor.comWhen booking flights, I use sites like Kiwi and Skyscanner that let you do flexible searches - multiple destinations, custom connections, creative routes, etc. But rail search feels oddly constrained. All the UK train operators offer basically the same experience, and surface the exact same routes. I always suspected there were better or just different options that weren’t being shown. Where is the "Skyscanner for trains"?After digging through the national rail data feeds, I decided to have a go at building my own route planner that runs completely offline in the browser. This gave me the freedom to implement more complex filters, search to/from multiple stations, and do it without a persistent network connection.Now I'm finding routes that aren't offered by the standard train operators, connecting at different stations, and finding it's often easier to travel to different stations (some I'd never heard of) that get me closer and faster to where I actually want to go!It's still a little rough and I'd like to add more features such as fares, VSTP data, and direct-links to book tickets, but wanted to share early and get some initial feedback before investing more time into it. So, thanks in advance - let me know what you think.

cryptoz: AST-based code edits from LLMs: https://codeplusequalsai.comIt's an LLM-webapp-builder, sure, but different from the rest! I have the LLM write python code when it needs to modify an HTML file for example (it'll use beautifulsoup; then I run the code: it parses the source into a data structure, modifies the data structure, and then outputs the resulting html).It's also a marketplace where you can publish your llm-powered webapp, and earn $ on the token margins (I charge 2x token rates) when people use your site.

frankfrank13: looks cool! i read `faction-identity.md`, i feel like if you come up with a little more lore, a name may come to you
