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

Ask HN: Does the tech industry require deterministic ML training?

Hey, I was wondering whether the tech industries require deterministic ML training or is non-determinism acceptable? As in, I know in case of LLMs, small float differences while training are generally tolerated as the model converges to similar quality regardless. But in more specific domains like medical device certification or autonomous vehicle safety validation or financial model auditing, I feel like whether two training runs producing bit identical models would be critical whether two trai

Ask HN: What's expected from an engineering manager or director now?

I just joined a 30-person AI startup in the Bay Area as Director of Engineering.Two non-coding founders (CEO and CTO) and a flat team. We have 2 PMs, 20 engineers. Every engineer is senior or staff level. They use Claude Code and AI agents etc quite well.What is my job in an environment like this? According to the CTO, I'm to improve the velocity and productivity while also balancing quality.Also, are there any Bay Area meetups or peer groups where engineering leaders are actually talking a

Ask HN: Are you using Rust on embedded devices yet? If not, why?

I started dabbling with ESP32-based MCUs from Waveshare with Rust, and I'm quite impressed with the state of things (esp-rs, embassy, probe-rs etc). Note that I haven't really done embedded in any other languages, so I don't really have anything to compare it with.One thing I did notice was that creating beautiful, interactive user interfaces on MCUs with displays is a little harder, libs like embedded-graphics don't look that great.This made me wonder, are people using Rust

Show HN: A browser-based video editor that renders videos directly with FFmpeg

Weave is a React app that provides a multi-track timeline editor to perform basic video edits like trimming, stitching, transitions, audio tracks etc. which maps directly to an FFmpeg command to render the video.I tried my best to have the React "video" preview closely replicate the FFmpeg lavfi filtergraph output, but naturally this is not perfect (especially replicating the `eq` filter using SVG filters is quite inaccurate).I've built this as a prototype for another project I&#x

Show HN: Dub Any Podcast in Your Language Using Local Models

Worth mentioning that the pipeline uses all open-weight models, though for the demo I used Kimi K3 for the translation piece due to the Kimi founder being interviewed.Have a listen for yourself: https://www.youtube.com/watch?v=92BQg2oozBgThe pipeline can be mostly run locally on an M-series Mac with at least 16 GB of RAM.The translation stage is the main quality constraint but local models are getting better and better. Could see a specialized 30B model be more than enough here.Di

Show HN: Dozenal – A Game of Spatial Arithmetic

Hello HN! We're Rory and Chris, and we've made a game called Dozenal[0], a grid-based number puzzle game where the objective is to use all the tiles on the board to create totals of 12 (hence the name).We think the mechanic is quite unique, although keen to hear if people know of similar games! You essentially drag tiles across the board, and the distance between two numbers decides the arithmetic operation when they connect to each other: zero spaces is addition, one space is subtract

Show HN: Sekey.sh – Manage SSH Keys in Apple Secure Enclave

Since I used MacBook with TouchID, I've been using SeKey (by Nicolas Trippar) to manage my SSH keys. It come with 2 advantages: the private keys are non-exportable and I will be asked for TouchID everytime a program needs SSH authentication. I'm happy with that setup because I won't worry about leaking my private keys and the authentication is quite convenience, until recently: the project is abandoned, no Apple Silicon build and macOS will end the x86 support soon. Then I found o

Show HN: Tilde Pay – Give your AI agent a bank account to pay for things

hey HN, I'm Daniel - I built Tilde Pay during a hackathon I took part in and couldn't stop working on it. It's an MCP server you can give your AI agent to buy things online with. It can process both x402, MPP payments & (hopefully soon), any card checkout form online.When you sign up, you get EUR and USD denominated bank account details to send deposits to which convert to USDC within a minute of receipt for your agent to spend in their own crypto wallet. You can then add the

Show HN: Watch 14-Byte AI "brains" attempt to solve a 2D maze (Its hard)

Hey HackerNews,I built this project over the last few weeks as a palette cleanser from a failed game launch.I wanted to learn a bit about AI/Neural-Networks and naively thought I could build a tiny maze-solving AI in a weekend with a 100% solve rate.Well - I couldn't, but I got pretty close. 14 Bytes total model size, and a 96.5% solve rate on unseen mazes. Trained across 46 phases experimenting with different ideas to improve the model (better performance, smaller size).Its quite fun

Researchers are building computers that run on brain organoids — but have neglected a major ethical issue

'Feynman and followers, you guys are off': Physicists disprove decades-old Richard Feynman theory on 'silly' sprinklers

Richard Feynman was a serious physicist who loved to answer unserious questions. Can math tell you how to order the optimal lunch? Can a human track scents like a bloodhound can by smelling his own footprints? Now, researchers have picked up one of Feynman's most curious unanswered questions by looking at the physics of "silly" sprinklers.A typical lawn sprinkler with an S-shaped nozzle spins in a given direction as it spews water from its two openings. But if you thr

Why Jupiter has several giant moons but Saturn has only Titan

Young Jupiter’s powerful magnetic field may have created a safe zone where several large moons could survive. Saturn lacked this protection, possibly explaining why Titan stands almost alone among its largest moons.
