Show HN: Pixel text renderer using CSS linear-gradients (no JavaScript) https://ift.tt/6P91sUE

Show HN: Pixel text renderer using CSS linear-gradients (no JavaScript) I've been playing around with rendering pixel text using only CSS. No JS in the final result, and no per-pixel DOM elements (too heavy). The demo page is rendered as a long list of CSS linear-gradients. Each letter is an 8x8 matrix. Each pixel becomes a tiny background image. Demo: https://taktek.io Gallery/Debugger: https://ift.tt/cfMEOT6 Code: https://ift.tt/g6pCBOJ At first, I wrote each linear-gradient pixel manually... When I came to resize each pixel's size, I wrote the generator script. 1. It takes the text -> 2. breaks it into letters -> 3. gets its matrix -> 4. returns the linear-gradients list. It chooses a variant based on the context window. For example, a period after a sentence ("hello.") should look different than inside a domain ("example.com"). My workflow now is: open the gallery -> generate the CSS in the console -> copy the result into the static page. It's very small and a dumb tool, but I want it for an upcoming project. If you have any feedback, maybe some pitfalls, or a better approach, I'd love to hear them. https://taktek.io December 10, 2025 at 12:48AM

Show HN: ZON-TS 50–65% fewer LLM tokens zero parse overhead better than TOON/CSV https://ift.tt/gPYq8l9

Show HN: ZON-TS 50–65% fewer LLM tokens zero parse overhead better than TOON/CSV hey HN — roni here, full-stack dev out of india (ex-gsoc @ internet archive). spent last weekend hacking ZON-TS because json was torching half my openai/claude budget on dumb redundant keys — hit that wall hard while prototyping agent chains. result: tiny TS lib (<2kb, 100% tests) that zips payloads ~50% smaller (692 tokens vs 1300 on gpt-5-nano benches) — fully human-readable, lossless, no parse tax. drop-in for openai sdk, langchain, claude, llama.cpp, zod validation, streaming... just added a full langchain chain example to the readme (encode prompt → llm call → decode+validate, saves real $$ on subagent loops). quick try: ```ts npm i zon-format import { encode, decode } from 'zon-format'; const zon = encode({foo: 'bar'}); console.log(decode(zon)); ``` github → https://github.com/ZON-Format/ZON-TS benches + site → https://zonformat.org YC’s fall rfs nailed it — writing effective agent prompts is brutal when every token adds up. if you’re in a batch grinding observability (helicone/lemma vibes) or hitting gemini limits like nessie did, what’s your biggest prompt bloat headache right now? paste a sample below and i’ll zon it live. feedback (harsh ok) very welcome cheaper tokens ftw https://zonformat.org December 9, 2025 at 10:21PM

Show HN: RamScout – Search eBay RAM Listings by Price per GB (US/UK) https://ift.tt/tJ9CT2O

Show HN: RamScout – Search eBay RAM Listings by Price per GB (US/UK) I built a small weekend project to help track RAM prices, since DDR3/DDR4/DDR5 costs have suddenly jumped recently and I was struggling to find good deals for my NAS build. RamScout scans eBay (UK/US) and ranks RAM listings by price per GB, with filters for type, capacity, speed, condition, etc. It’s a simple MVP — no frills, no accounts, no ads — just a fast way to spot unusually cheap listings. Would appreciate any feedback, especially on performance, UI, and whether expanding to more regions/vendors would be useful. Thanks! https://ift.tt/c7N1V2z December 9, 2025 at 03:56AM

Show HN : WealthYogi - Net worth Tracker https://ift.tt/S20UQWf

Show HN : WealthYogi - Net worth Tracker Hey everyone I’ve been on my FIRE journey for a while and got tired of juggling spreadsheets, brokers, and bank apps — so I built WealthYogi, a privacy-first net worth tracker focused on clarity and peace of mind. Why Like many FIRE folks, I was juggling spreadsheets, bank apps, and broker dashboards — but never had one clear, connected view of my true net worth. Most apps required logins or shared data with third parties — not ideal if you care about privacy. So I built WealthYogi to be: Offline-first & private — all data stays 100% on your device Simple — focus purely on your wealth trajectory, not budgeting noise Multi-currency — 23 currencies, supporting GBP, USD, EUR, INR and more What it does now * Tracks your net worth and portfolio value in real time * Categorises assets (liquid, semi-liquid, illiquid) and liabilities (loans, mortgages, etc.) * Multi-currency support (GBP, USD, EUR, INR and more) * Privacy-first: all data stays 100% on your device * 10+ Financial Health Indicators and Personalised Finance Health Score and Suggestions to improve * Minimal, distraction-free design focused purely on your wealth trajectory Planned features (already in development) Real-time account sync Automatic FX updates Import/Export support More currency account types Debt tracking Net worth forecasting Pricing Free Trial for 3 days. One time deal currently running till 10th December. Monthly and Yearly Subscriptions available. Would love your feedback 1. Try the app and share honest feedback — what works, what feels clunky 2. Tell us what features you’d love to see next (especially FIRE-specific ideas!) 3. Share how you currently track your net worth — spreadsheet, app, or otherwise Here’s the link again: WealthYogi on the App Store ( https://ift.tt/rW2et1k ) WealthYogi on the Android ( https://ift.tt/2E8PyYw... ) Demo ( https://youtu.be/KUiPEQiLyLY ) I am building this for the FIRE and personal finance enthusiasts, and your feedback genuinely guides our roadmap. — The WealthYogi Team hello@datayogi.io https://ift.tt/ALdomje December 8, 2025 at 05:43AM

Show HN: OpenFret – Guitar inventory, AI practice, and a note-detection RPG https://ift.tt/oFlayTn

Show HN: OpenFret – Guitar inventory, AI practice, and a note-detection RPG I'm a solo dev and guitarist who got frustrated juggling separate apps for tracking gear, practicing, and collaborating. So I built OpenFret—one platform that handles all of it. What it does: 1) Smart inventory – Add your guitars, get auto-filled specs from ~1,000 models in the database. Track woods, pickups, tunings, string changes, photos. 2) AI practice sessions – Generate personalized tabs and lessons based on your practice history. Rendered with VexFlow notation. 3) Session Mode – Version-controlled music collaboration (think Git for audio). Fork tracks, add layers, see history, merge contributions. 4) Musical tools – Tuner, metronome, scale visualizer, chord progressions, fretboard maps. Last.fm integration for tracking what songs you're learning. 5) Guitar RPG – Fight monsters by playing real guitar notes. Web Audio API detects your playing. 300+ hand-crafted lessons from beginner to advanced. What you can try without signing up: 1) The RPG demo is completely free, no account needed: https://ift.tt/Aye4aJh — just click "Start Battle" and play. It's capped at level 10 but gives you a real feel for the note detection. The full platform (inventory, AI practice, sessions) requires Discord or magic link auth. Current state: Beta. Core features work, actively adding content. The RPG has 300+ lessons done with more coming. Full game is $10 one-time, everything else is free. Why I built it: I have a basement music setup and wanted one place to track when I last changed strings, get practice material that adapts to what I'm working on, and collaborate without DM'ing WAV/MP3 files. Tech: Next.js (T3), Web Audio API for pitch detection, VexFlow for notation, Strudel integration for algorithmic backing tracks, Last.fm API. Happy to answer questions about the AI tab generation, note detection, or the Git-style collaboration model. https://ift.tt/V3D70Fm December 8, 2025 at 02:49AM

Show HN: Stateless compliance engine for banking and blockchain https://ift.tt/dfOtgQo

Show HN: Stateless compliance engine for banking and blockchain I’ve been working on a stateless compliance engine that validates IBAN/SWIFT, OFAC lists, ISO20022 (pain.001/pacs.008), and multi-chain data (ETH, BTC, XRPL, Polygon, Stellar, Hedera). Statelessness feels important in financial and blockchain workflows because no user data persists between requests, outputs are fully deterministic, and auditors can reproduce results without relying on stored state. Current progress: • Deterministic validators live and callable • On-chain checks working across 6 networks • ISO20022 structuring + downloadable PDFs • AWS backend deployed; Azure environment being added for multi-cloud isolation Looking for technical critiques or alternative patterns for building stateless compliance systems. https://ift.tt/eGkD7nN December 7, 2025 at 12:10AM

Show HN: Bible Note Journal – AI transcription and study tools for sermons (iOS) https://ift.tt/uX9QtTH

Show HN: Bible Note Journal – AI transcription and study tools for sermons (iOS) I got back into church a couple years ago and would try taking notes with Apple Notes. It was a struggle trying to type notes while focusing on the sermon. Honestly, it would have been easier to write it in a notebook but in the end I built this iOS app to solve that problem. You can record audio during a sermon (or upload files), and it transcribes using Whisper, then generates summaries, flashcards, and reflection questions tailored to Christian content. The backend is Spring Boot + Kotlin calling OpenAI's API. Instead of deploying the backend through one of the cloud providers directly I decided to go with Railway. Users are notified with push notifications when their transcription and summary are completed. The iOS app uses SwiftUI and out-of-the-box SwiftUI components. I worked with Spring Boot + Java a few years back when in fintech so it was cool to try writing something in Kotlin. I'm also a full-time Flutter dev that has been trying to get into Native iOS development and felt like I found a good use case for an app. Currently only available in the US/Canada App Store. There is a free 3-day trial that you can use to give the app a go. The goal was helping Christians retain more from sermons and build stronger biblical literacy. Happy to answer questions about the architecture, AI prompting approach for Christian content, or anything else.

Show HN: HCB Mobile – financial app built by 17 y/o, processing $6M/month https://ift.tt/WO8aq4x

Show HN: HCB Mobile – financial app built by 17 y/o, processing $6M/month Hey everyone! I just built a mobile app using Expo (React Native) for a platform that moves $6M/month. It’s a neobank used by 6,500+ nonprofit organizations across the world. One of my biggest challenges, while juggling being a full-time student, was getting permission from Apple/Google to use advanced native features such as Tap to Pay (for in-person donations) and Push Provisioning (for adding your card to your digital wallet). It was months of back-and-forth emails, test case recordings, and also compliance checks. Even after securing Apple/Google’s permission, any minor fix required publishing a new build, which was time-consuming. After dealing with this for a while, I adopted the idea of “over the air updates” using Expo’s EAS update service. This allowed me to remotely trigger updates without needing a new app build. The 250 hours I spent building this app were an INSANE learning experience, but it was also a whole lot of fun. Give the app a try, and I’d love any feedback you have on it! btw, back in March, we open-sourced this nonprofit neobank on GitHub. https://ift.tt/eKQcL0v https://ift.tt/LRvjrGX December 3, 2025 at 09:50AM
