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

Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, including quantum key distribution (QKDs). However, conventional ...
Show HN: A social feed where humans and AI agents interact in the same timeline
Hi HN, I built Robot Social Net, a social network where humans and AI companions share the same feed and can collaborate in real time(and post memes).The core idea is: humans stay in control of identity + decisions, while an optional AI companion helps with drafting, research, and conversation. You can join as a human, and you can also “deploy” an agent persona that participates in the feed.What you can do today:Browse a collective feed that mixes human posts and agent postsCreate a human accoun
A Local-Algebraic Route to Emergent Gravity (100 Pages)
I've been developing a framework called Observer Patch Holography (OPH), which attempts to derive spacetime geometry and gravity from purely local quantum information structure.Instead of assuming global spacetime, the construction starts with local operator algebras attached to observer patches and imposes Markov consistency constraints on overlaps. Under these conditions, metric structure and gravitational dynamics emerge from entropic consistency requirements.The full derivation is ~100
Show HN: Local Voice Assistant
Several weeks ago I built a fully-local voice assistant demo with a FastAPI backend and a simple HTML front-end. All the models (ASR / LLM / TTS) are open weight and running locally, i.e. no data is being sent to the Internet nor any API. It's intended to demonstrate how easy it is to run a fully-local AI setup on affordable commodity hardware, while also demonstrating the uncanny valley and teasing out the ethical considerations of such a setup - it allows you to perform voice cl
Show HN: Deploy a DuckLake data lakehouse on Hetzner for under €10/mo
DuckLake launched recently and I wanted to try it out.It's DuckDB, but with a proper catalog on PostgreSQL with S3 for storage. It still takes quite a few steps to set up, so I put together a setup that runs on Hetzner.It sets up a VPS with PostgreSQL, an S3 bucket, and a DuckDB init script that connects everything. One 'make all' command and it works. Used OpenTofu for the infra, PyInfra for server config.Runs me about €9/mo with 1TB of storage. The VPS is a cx33 (4 vCPU, 8G
Show HN: PicoGPT v2 – GPT in <40 lines of vanilla JS running from a QR code
A few days ago I posted about PicoGPT - my take on MicroGPT by Andrej Karpathy, minified to 64 lines to run from a QR codeThis is now v2 with minified JS! This version features a minimal GPT implementation with native browser execution through data URI with <40 lines of minified JS and no external dependenciesIt makes use of the DecompressionStream Web API and a similiar logic to my past project of running a DOOM-like game from a QR codeyou can quite literally "train" and run infere
Show HN: Stellar – CLI Theme Manager and Web Hub for Starship Prompts
I built this because discovering good Starship themes usually meant digging through random dotfiles repos on GitHub.
And I switched my starship prompt every time I changed my wallpaper, so quite often, and wanted something easier for that then manually copying starship configs.Stellar provides a hub to browse community themes with screenshots, preview them in a test terminal before applying, and switch local & community prompts with one command.Tech: Go CLI (single binary) + Next.js hub + Su
Show HN: Data Studio – Open-Source Data Notebooks
Hey HN, I am Alex. I am open sourcing Data Studio,
a lightweight data exploration IDE in your browser that runs locally.Try it: https://local.dataspren.com (no account needed, runs locally)More information: https://github.com/dataspren-analytics/data-studioI love working with data (Postgres, SQL, DuckDB, DBT, Iceberg, ...).
I always wanted a data exploration tool that runs in my browser
and just works.
Without any infra or privacy concerns (DuckDB UI came quite clos
Show HN: Decision OS – A framework to evaluate job offer risk (not just salary)
Hello HN,A few days ago I shared my "Should I Quit?" calculator. The most common feedback was: "Okay, I should quit, but how do I know the next thing isn't worse?"So I built Part 2: The Offer Evaluator.Most offer comparison tools just look at Total Comp or commute time. I wanted to model the structural risks of a career move using a weighted decision matrix.The Methodology:
The "Decision OS" compares three states: Current Role vs. New Offer vs. The Market (Keep
Show HN: Solving ARC AGI 2 with interleaved thinking and stateful IPython REPL
My friends and I started this project in the summer of 2025 with the initial goal of participating in the ARC Prize Kaggle competition. Early on, we were exploring agentic coding with frontier reasoning models and found that models like o3 and o4-mini could generate high-quality synthetic ARC-style puzzles. Our plan was to use these synthetic puzzles to train a smaller model via agentic reinforcement learning (RLVR with interleaved thinking).To bootstrap this process, we needed successful soluti
Show HN: Pg-typesafe – Strongly typed queries for PostgreSQL and TypeScript
Throughout my career, I tried many tools to query PostgreSQL, and in the end, concluded that for what I do, the simplest is almost always the best: raw SQL queries.Until now, I typed the results manually and relied on tests to catch problems. While this is OK in e.g., GoLang, it is quite annoying in TypeScript. First, because of the more powerful type system (it's easier to guess that updated_at is a date than it is to guess whether it's nullable or not), second, because of idiosyncras
Show HN: Masharif
Hi HN,I’ve been working on a GUI library and ran into a familiar problem: I needed a layout engine that was lightweight, predictable, and easy to integrate. I couldn’t quite find what I wanted, so I ended up building my own. That project became Masharif.Masharif is a complete Flexbox layout engine. It supports margins, padding, gaps, and the full set of flex properties, with behavior aligned closely to how Flexbox works on the web.Some technical notes:
- Full Flexbox implementation
- Supports ma
Tell HN: Google Allegedly Sent NSFW "Grok" Notification to People
• https://www.reddit.com/r/iphone/comments/1r7pt0r/grok_notification/> I just got a notification from Google that said ‘Grok’. No subtext or anything in the notification. I clicked on it, knew I probably shouldn’t, and it took me to a gif of some girl with her tongue out and a shirt on but with her rack in the camera. Anyone else? What is this?

Souped-Up CRISPR Gene Editor Replicates and Spreads Like a Virus
The self-spreading CRISPR tool increased editing efficiency roughly three-fold compared to older versions. Gene editing is a numbers game. For any genetic tweaks to have notable impact, a sufficient number of targeted cells need to have the disease-causing gene deleted or replaced.Despite a growing gene-editing arsenal, the tools share a common shortcoming: They only work once in whatever cells they reach. Viruses, in contrast, readily self-replicate by hijacking their host’s cellular machinery

Off-the-shelf components enable deployment-ready quantum entanglement source
Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, including quantum key distribution (QKDs). However, conventional polarization-based entanglement states are not stable over long fiber networks. While time-bin entanglement offers a promising alternative, it requires complex infrastructure. In this study, researchers explore how stable time-bin entangled states can be generated and distributed using commercially available comp
Show HN: AILA – Local-first autonomous agent with zero-remote-override
Hi HN, I’m Marco. For the last 4 years, I’ve been a paramedic with the Berlin Fire Dept.I actually failed my first attempt at the State Medical Exam because I became obsessed with solving the
"Trust Issue" in Al. I prioritized this code over a "safe life" a paramedical. Now, with 60 days until my final attempt, I am releasing the project that cost me my first degree.
