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: Can you stay relevant against AI via specialization

I've had a lot of discussions with peers about the possibility of us being replaced via ai agents and how to stay relevant, given a future where AI intelligence keeps improving to the point of being capable of replacing potentially any job.My personal strategy is specialization, because I've noticed that I cannot work with AI in hard domains that I haven't got a background in. For example, I've tried to use claude opus to understand a phd thesis in quantum physics from a frie

Is CPU design hitting a (soft) speed limit?

I'm not in the hardware industry, and am curious what the future might hold.We've been stuck in the 3-5 Ghz range for a long time. I think we're scaling by adding cache, cores, and specialized instructions. Due to observations like Amdahl's Law, PC hobbyists aren't seeing great returns on new machines. We've had 8+ logical cores for a long time now.The physical size of gates in the CPU is getting very difficult and costly for companies to shrink further. We are appr

Ask HN: Year of Linux Desktop is fun with LLMs

I'm wondering if others are also having recently blast using Linux desktop thanks to Claude/Codex/Grok CLIs?As 20y daily Mac user, occasionally using Linux as desktop, my personal daily OS now gravitated towards Linux desktop in recent months quite a lot.I attribute it purely to LLM CLIs. Even my old 2012 Intel iMac 27" on Linux became really good and pleasant machine to use. After dusting it off and setting it up I don't want to give it away anymore.Solutions to quirks&

Show HN: Ray Hosting – Topology-aware game server orchestrator made from scratch

Hey HN, I have built a game server orchestrator from scratch, As a solo-dev it took me 3+ years and almost 10 hours daily to finally complete it since i started in the beginning of 2023. Im 26 years old now!.The complexity and stuff i had to research to complete this project i couldnt have imagined them even in my dreams, but hey, here it is, my greatest professional achievement until now.Down below I will try to break down just some of the core and most important features of my game server orch

I built a bookkeeping app for UK sole traders as a new developer using AI

About a month ago I started building QuarterPerfect — a bookkeeping tool aimed at UK sole traders and landlords, specifically designed around the MTD ITSA changes coming into effect this year (first quarterly deadline: 7 August).A bit of background on me firstly.I'm not a senior developer. My previous project was a small roster app that converted an XLSX shift rota into a calendar with annual leave support — mostly built for me and a few colleagues at work. Nothing with real users, nothing

Ask HN: How are you enabling your employees to do AI dev in the cloud?

Sure, us engineers can Claude Code up a storm locally on our laptops these days. But now with everyone trying to vibe code everything, there's quite a few people that don't have a "proper" local dev environment to do that same kind of development. Let's just take running a test suite. Our devs need a pretty beefy environment to run that.So ideally, these environments are just in the cloud. But Claude Code web, is so "environment lite" that it really isn't

Show HN: 0-0.io – Multiplayer browser football with server-authoritative physics

Hi everyone, dev here. I made a real-time minimalistic football game (in the lineage of HaxBall) in time for the championship, and thought to turn it into an actual multiplayer game polished for release. It should run in any browser, desktop/tablet/mobile as well and requiring no sign-up for instant play. If there are no people to fill in the slots (which will likely be the case as it's brand new) you can also choose to start with bots to play against. I tried to balance the bots

Safety Ideas, and a Testable Path

Hello. You don't know me. I know of some of your stories from across the varied aspects of technology, and have followed or many years. I am not a developer. I am not from a computer science background. And I'm not from Silicon Valley. I used to respect Silicon Valley quite a bit. And I've proved about the technology our world is currently suffering at the hands of. Since before, most of the people that had a hand in building it were even alive. Like... Come from a very different

Japan Thinks Swarms of Transformer Robots Could Explore the Moon

A tiny robot developed by Japan’s space agency operated autonomously on the moon for more than 100 minutes and sent a series of images back to Earth. Exploring the moon’s surface lays crucial groundwork for future crewed settlements, and swarms of tiny robots could be the key. Now researchers have given the first demonstration of the idea after a palm-sized rover autonomously navigated the moon and transmitted images back to Earth.The moon is a tough environment for robots. Its surface is

At-home brain implant gives man with motor neuron disease his daily life back

Abstract algebra unlocks distinguishable states for quantum systems

Researchers around the world are racing to develop new quantum-based systems for sensing, communication, computing and control that have the promise of outperforming traditional systems. Creating stable, measurable, distinguishable quantum states—which would be the heart of any such system—is a daunting task.

Redefined conformity model beats averaging in five real-world tests of opinion dynamics

Imagine you poll your friends on how many minutes per pound to roast a turkey. Five respond with 15 minutes; one answers 33 minutes. The most popular model of conformity, the French-Harary-DeGroot model (or more commonly, DeGroot model), assumes that you would carefully weigh all six recommendations, calculating a cooking time of 18 minutes per pound. But under a model of conformity previously published by SFI Complexity Postdoctoral Fellow Kaleda Denton and colleagues, you would disregard the o

Tell HN: Forget selectors and screenshots. The agentic web lives in your shell

These old ways are too heavy.

Ultrafast laser pulses reveal a material's hidden state of matter

What would it take to instantly transform a material from an electrical insulator into a conductive state without ever touching it? Using ultrafast laser pulses and powerful X-rays, scientists at the National Synchrotron Light Source II (NSLS-II)—a U.S. Department of Energy (DOE) Office of Science user facility at DOE's Brookhaven National Laboratory—developed a methodology to generate "hidden" phases and understand why they work.

Passive quantum error correction doubles qubit lifetime, reaching break-even point

A team of U.S. researchers has designed a passive quantum error correction technique that enables qubits to correct their own errors. Demonstrated by Shruti Shirol and colleagues at the University of Massachusetts Amherst, the protocol transforms the inevitable dissipation of energy in qubit systems from a hindrance into an advantage, offering a promising route toward practical quantum computing outside the lab. The research has been published in Physical Review X.

This strange material can become strong or fall apart in seconds

Scientists have found that staple-shaped particles can tangle together to create a material that is both strong and flexible. Unlike conventional materials, these particles can be locked into a sturdy structure or rapidly unraveled using vibrations. The unusual behavior could open the door to recyclable buildings, reconfigurable structures, and even futuristic robotic technologies.

Quasi-1D material unlocks electric control of charge waves beyond standard limits

The ability to control the movement of negatively charged particles (i.e., electrons) is central to the functioning of all modern electronic devices. This control is typically attained using a gate, an electrode via which an applied electric field alters a material's electrical properties.
