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: I can't seem to text properly on an iPhone, so I built my own keyboard

== The problem ==I’ve never been able to text properly on a phone. I’ve tried with two thumbs, one thumb, and every other way I can think of. Nothing works for me. I can only seem to text with my right index finger while holding the phone in my left hand, which is at best is slow and full of typos. I find myself fighting autocorrect as much as using it. I tried swipe keyboards (gboard, etc.) but they didn't help. Sometimes I watch people texting rapidly with both thumbs and marvel at t

Show HN: Replen – maps your repos to a knowledge graph to match open-source

Hi all. I built Replen as a way to improve my AI dev workflows. In essence, it automates what was a manual process for me and turns it from a reactive stance to a proactive one. That being reading/ scrolling lists and creators that showcased cool and trending repos. If i saw something I liked i’d then manually checked with Claude or Codex to see if theres anything here worth taking because I had a hunch there might be. Replen now does this for me. And cuts out a number of back and fourths

Show HN: I built a smart proxy so your coding agent can run loose

The only way to go fast is full YOLO mode in your coding agent. I've got the local sandbox figured out (pro tip: Incus VMs work great) but I wanted to keep my agents from doing things like inadvertently blowing up my cloud services or chasing a prompt to POST to some random website. I struggle most with this on my side projects where my permission model isn't quite as robust as it is at the office.I started with a firewall on the Incus container but every time the agent needed access t

Show HN: Simulator for a custom 8-bit discreet logic computer

5 years ago, I made a derivative of SAP-1 (mainly inspired by Ben Eater) on breadboard with few improvement and called it MSAP-1 (https://github.com/mehrantsi/MSAP-1) I made my own very primitive Assembly language and a simple Arduino programmer (https://github.com/mehrantsi/8-bit_CPU_Programmer) where I could load my programs onto MSAP-1 and even Debug them (https://github.com/mehrantsi/8-bit_CPU_Debugger).After that I started worked o

Show HN: Cascade Chat – A Hackable IRCv3 Client for macOS, Windows, and Linux

Hello HN! I'm Matt and today I'd like to show you Cascade Chat.One of my earliest internet experiences was with mIRC. I always admired its straightforward, pleasant UI and the way it wove a hackable core into the code. The way you could build on the visual and API layers of the underlying IRC client to me was fascinating software machinery. It was truly a client that you could build on top of.As my career has progressed, I moved away from Windows and adopted Linux as my daily driver. T

Show HN: Multi-player poker on SSH – ssh cli.poker

my motivation - i was looking for some CLI games to play when the agent is working and this idea came into my head. this was when fable was available for 3 days, so seemed like a good use of tokens to try and build this out. spent some time polishing to finally get this out.the public matchmaking connects you on a first come first serve basis to anyone else in the world. there is a bot that will connect in-case a match is not found for 45 seconds. games last about 5-10 minutes (tournament style

Show HN: I made my note-taking system self-hosted after HN asked

6 months ago [0] I did a Show HN for Docket - it’s a system for active note taking in regular meetings like 1-1s, stands, all-hands, etc.On that thread a few of you asked for a self-hosted version. So I built it.There's a free tier available. I put loads of effort into making setup easy - just one install command that gives you a CLI for start/stop/upgrade commands etc.It runs as a single container, you can use a custom domain out the box for hosting over the internet (it provisio

Show HN: WebMotion, a browser native library for deterministic video composition

Hi HN! I have been building WebMotion, a small library for making videos in the browser.The basic idea is that everything on screen is a pure function of the current frame, so rendering frame N always produces the same result. That means you can seek anywhere in the timeline, and exports are frame accurate without needing a server.Demos (each includes its own source): https://superhq-ai.github.io/webmotion/The repo also includes an agent skill that lets coding agents create l

Ask HN: How do you do marketing in the age of slop?

Hi dear hackernewsfolks, vocal contributors and lurkers alike.We (that is to say my business partner and I) are building SaaS products, but we are really struggling to find enough users. This is an age old problem, but I find it has gotten particular bad after LLMs made it trivially to make apps and services. Whether these products end up good or bad is mostly irrelevant, the end effect is the same: the market just seems so heavily saturated with new products, that it's incredibly hard to b

Show HN: ForkUnion v3 – Faster OpenMP-style thread-pool for C, C++, Rust, & Zig

Hi community! Wanted to share a project of mine that is now enabling parallelism across many of my open-source projects: ForkUnion.The absolute majority of "thread pool" projects on GitHub are `std::deque<std::shared_ptr<task_t>>` task queues guarded by a `std::mutex`. I'm not sure which part of that equation I'm more allergic to, but I knew I had to find an alternative. It probably exists somewhere, but I ended up implementing everything from scratch last year.Th

Astronomers just found four hidden white dwarf stars near Earth

Four nearby white dwarf stars have been discovered hiding in plain sight beside brighter red dwarf companions. Hubble's ultraviolet observations finally revealed the long-hidden stellar remnants, including one just 25 light-years away that took nearly three decades to confirm. The findings match long-standing predictions and suggest our corner of the galaxy may contain many more undiscovered white dwarf binaries.

Scientists Find a Surprising New Way Stress Cascades From Brain to Body

A newly discovered brain-gut-bone marrow highway in mice could inspire strategies to protect immunity from chronic stress. Stress does more than take a toll on mental health. After a particularly taxing week or month, it’s easier to catch a cold and harder to recover. Health issues build up as stress lingers, raising the risk of heart disease, diabetes, cancer, and a weakened immune system.Chronic stress is often treated as an unavoidable part of modern life. While therapy can help people cope,

New atomic trap boosts quantum performance by using surface forces

Researchers at Humboldt-Universität zu Berlin have developed a new method for trapping and controlling atoms near an ultrathin glass fiber. This has significantly improved the atoms' ability to store quantum information—an important step forward for future quantum technologies.
