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

Researchers unlocked a new shortcut to quantum materials

Scientists are learning how to temporarily reshape materials by nudging their internal quantum rhythms instead of blasting them with extreme lasers. By harnessing excitons, short-lived energy pairs that naturally form inside semiconductors, researchers can alter how electrons behave using far less energy than before. This approach achieves powerful quantum effects without damaging the material, overcoming a major barrier that has limited progress for years.

A tiny spin change just flipped a famous quantum effect

When quantum spins interact, they can produce collective behaviors that defy long-standing expectations. Researchers have now shown that the Kondo effect behaves very differently depending on spin size. In systems with small spins, it suppresses magnetism, but when spins are larger, it actually promotes magnetic order. This discovery uncovers a new quantum boundary with major implications for future materials.

Can small microfactories make fast fashion economically viable at low MOQ?

I'm exploring a concept for small-scale apparel microfactories aimed at reducing inventory risk and lowering minimum order quantities (MOQ) for fast fashion brands.Rough assumptions: - Target throughput: ~200 garments per day per microfactory cell. - Goal: reduce MOQ from hundreds per SKU to <50 units without exploding unit cost. - Production organized into semi-automated cells (cutting, sewing, QC). - Demand signals from online sales feed lightweight forecasting and replenishment.What I

Ask HN: What are the metrics for "AI-generated technical debt"?

Here’s one place where I think proponents and skeptics of agentic coding tools (Claude Code, Codex, etc.) tend to talk past each other:Proponents say things like:- “I shipped feature X in days instead of weeks.”- “I could build this despite not knowing Rust / the framework / the codebase.”- “This unblocked work that would never have been prioritized.”Skeptics say things like:- “This might work for solo projects, but it won’t scale to large codebases with many developers.”- “You’re trad

Ask HN: How to introduce Claude Code to a team?

I am responsible for a small team of software engineers, including an industry veteran of 30 years, a junior developer on their first job, plus a view mid-level to senior folks. We have been using AI tools like IDE-integrated Copilot suggestions or ChatGPT, and are working with the OpenAI API in our product for assistant experiences, but did not (as a team) use coding agents yet.I recently got introduced to Claude Code by a friend who quit their job to build a new product entirely on their own,

Show HN: ElkDesk – I rage-quit Zendesk and built my own

I run a few apps (AI Singer App, Pawtograph, TravelFeed). Support emails were eating 3+ hours of my day.Tried Zendesk. Spent 2 hours configuring triggers before I could reply to a single email. The $25/month turned into $298/month for my setup. Closed the tab.So I built something for myself:- Tickets left, conversation right (that's the whole UI) - AI suggestions trained on your replies, not generic stuff - Knowledge base that grows as you answer questions - 5 min setupLeft out on

Show HN: An open-source personal finance simulator with AI features

Hi HN,I'm Joe, the creator of Ignidash. In May, I quit my job at Meta to figure out what I wanted to work on next, and ended up on this. It's for DIY long-term financial planning, and includes US tax estimates, Monte Carlo simulations, historical backtesting with real market data, AI chat & insights, and more.The hypothesis for it is as follows: - As tools like Claude Code and Cursor become better & more popular, the value of being able to vibe (or regularly) code on top of the

Show HN: MicroState – JavaScript City Builder

I’ve been working on MicroState, a city builder prototype written entirely in vanilla JavaScript using the HTML5 2D Canvas API.My goal was to see how far I could get with a 2.5D isometric style simulation with vanilla JavaScript built very simply and drawn entirely with procedural generation for maps, tiles, roads, trees, buildings, etc.The most interesting element is probably the terrain model, which allows for fairly arbitrary terrain.Although some of the generated graphics like trees are cach

Ask HN: Why don't tech companies provide housing?

Given most tech companies don't hire locally and people have to move into often quite HCOL areas for them, why don't large tech companies provide company housing? It could be a quite attractive option, especially for young graduates. Factories with large migrant workforces do it and it seems like large tech campuses could fit quite a bit of housing.

Code review your plans and your implementation

It’s 2026 and the human language now more or less compiles. We've slowly moved away from writing code and towards writing detailed plans. The plans have gotten to the point where they’re built into our tools(Cursor Plan mode, CC also has one). Why shouldn't we review these plans like its a code review?Eventually we won’t be looking at Python the same way we don't look at Assembly. I never check the binary output of a GCC compiler because I trust it. The workflow I’m seeing and usi

Ask HN: How are you sandboxing your coding agents?

I've seen a few articles here using bubblewrap, vagrant, VMs, even docker to sandbox coding agents to avoid the inevitable disaster. I've personally been using a headless VM but it's quite resource intensive and I'm wondering if there are better ways to do this.

Show HN: iOS app I made to track my anxiety

Hey HN! I'm the maker of Mudo.I built this because my therapist kept asking me to journal my anxiety, but every app I tried had 20 questions, 47 emotions, and felt overwhelming. I'd quit after 2 days.So I made the simplest possible version: 4 moods (Happy, Calm, Sad, Anxious), one tap, done. After 30 days I realized I'm not "always anxious" like I thought - just Sunday nights (work dread).Technical stuff: - Built with SwiftUI - Local-first storage (privacy-focused) - Opt

Show HN: Schema First React Router

I have been working on this experiment for quite some time and over the holidays I found sometime to polish things. I wanted to see if I can build a fully type-safe router, where everything from route params to search params was fully typed, even links.My main inspiration came from Servant [1]In Servant, you define a type-level API specification and then you use this type specification to:- Implement a web server- Generate client functionsI am still working on the API design and would love to ge

Show HN: I vibecoded a Test Management app for Jira

I'm a software tester since 2011. Become a Jira admin in 2013. Always wanted a tool which lives is inside jira and is a really cool test management app, where you can intuitively garden and execute your testing assets! When I decided to give it a go in 2016, found a tool which was almost perfect, called Kanoah Tests. That tool went through a lot, and as of today become one of the biggest app in jira (zephyr). But I found that they lost their mojo and stopped innovating, so after some very h
