MIT engineers develop a magnetic transistor for more energy-efficient electronics
Transistors, the building blocks of modern electronics, are typically made of silicon. Because it’s a semiconductor, this material can control the flow of electricity in a circuit. But silicon has fundamental physical limits that restrict how compact and energy-efficient a transistor can be.MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable smaller, faster, and more energy-efficient circuits. The material’s magnetism strongly

Show HN: WARN Firehose – Every US layoff notice in one searchable database
Hi HN,I built WARN Firehose because I was frustrated trying to track layoff data across the US. The WARN Act requires companies with 100+ employees to file public notices 60 days before mass layoffs — but the data is scattered across 50 state websites with different formats, broken links, and no API.WARN Firehose scrapes every state workforce agency daily and normalizes the data into a single database going back to 1988. It now has 131,000+ notices covering 14 million workers.*What you can do:*-
Is this cloud/local boundary for trading infra reasonable?
We’re two brothers from Kazakhstan building a B2B platform for quant research, backtesting, and controlled deployment.The main design choice we made is a strict cloud/local split.The cloud handles research, backtests, rollout artifacts, and redacted telemetry.
A local agent (running in the client environment) stores broker keys, sends orders, and enforces hard risk caps.
The cloud can only send lifecycle commands (start/stop), not order instructions.

Show HN: PureBee – A software-defined GPU running Llama 3.2 1B at 3.6 tok/SEC
This started as a question about simulation theory: if a GPU is just rules applied to a grid in parallel, do you actually need the silicon?Turns out, no.PureBee is a complete GPU defined as a software specification — Memory, Engine, Instruction Set, Runtime. It runs Llama 3.2 1B inference at 3.6 tok/sec on a single CPU core. The model answers questions correctly.What makes it different from llama.cpp or WebLLM:The WASM compute kernel is constructed byte-by-byte in JavaScript at runtime. No
Show HN: Elecxzy – A lightweight, Lisp-free Emacs-like editor in Electron
Hi HN. I am a programmer from Japan who loves Emacs. I am building elecxzy. It is a free (zero-cost), lightweight, Emacs-like text editor for Windows.I designed it to be comfortable and ready to use immediately, without a custom init.el. Here is a quick overview:- Provides mouse-free operation and classic Emacs keybindings for essential tasks (file I/O, search, split windows, syntax highlighting).- Drops the Lisp execution engine entirely. This keeps startup and operation lightweight.- Solv
Show HN: Xpaper – A Chrome extension to turn your X feed into a newsletter
Hi HN,I built Xpaper (https://github.com/laiso/xpaper), an open-source Chrome extension that curates and summarizes your X (Twitter) timeline into a clean, readable newsletter format.Like many of you, I wanted to distance myself from the endless scrolling of Twitter, but completely quitting wasn't an option—I still needed to extract the signal from the noise. I built this to solve that exact dilemma.I took a specific technical approach that I thought HN might find intere
Show HN: I Built an Offline Productivity System That Connects Goals and Systems
After years of building for companies, I finally built something for myself.Aura Tracker: Habits & Goals is now live on the iOS App Store.It's an opinionated productivity system that connects Identity → Goals → Habits → Tasks → Deep Work → Insights → Reflection, all in one smooth coherent flow. I built it because most productivity apps I used felt like productivity tools. Also, I was highly influenced by the multitude of books I read on the topic and wanted to build something for myse
Show HN: Ilove4o – a simple way to keep using GPT-4o
Hi HN,When OpenAI started phasing out GPT-4o from the main ChatGPT interface, I noticed a surprising amount of backlash — not about benchmarks or features, but about tone.A lot of people (myself included) felt that 4o had a certain conversational warmth that later models don’t quite replicate in the same way. That difference was subtle, but noticeable.So I built a small side project for myself: https://www.ilove4o.com/It’s a minimal interface that connects directly to GPT-4o via t
Show HN: I vibe-coded a custom WebGPU engine for my MMO
It took me about a week to vibe code this 3D game engine with Opus 4.6 that I intend to use as a replacement for Three.js and React Three Fiber in my browser MMORPG, Mana Blade.I was not expecting to be able to reach that point so easily, but pretty much every feature took somewhere between 30 minutes and 1 hour - 1 to 3 prompts on average. It is vibe-coded in the sense that I haven't looked at the code, but I am very careful with my prompts and constantly have Claude reviewing the codebase
Show HN: We wrapped US healthcare API in MCP and it became surprisingly usable
Hi HN,I’m building HealthPorta — an API layer for the US healthcare data (providers, plans, coverage, costs). Like most healthtech APIs, it started small… and then it didn’t. The surface area grew fast, integrations took longer than they should, and every new partner ended up needing a mini “tour guide” to use it correctly.So, since the last post here, something changed. We’ve built an MCP server as a boring integration helper to provide a smaller, friendlier interface for engineers of our "

Show HN: Habitless – A minimalist, privacy-first tracker to quit addictions
Hi HN,I built Habitless because I found that most trackers focus on building new routines, but the psychological challenge of quitting an addiction (like nicotine, alcohol, or even social media) requires a different approach.I wanted a high-precision dashboard that treats recovery like a mission. I just released an update that adds iCloud sync and milestone notifications.Key features:Precision Streak Counter: Tracks your progress down to the second.Financial Savings: A real-time tracker showing
