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
Silicon quantum processor detects single-qubit errors while preserving entanglement
Quantum computers are alternative computing devices that process information, leveraging quantum mechanical effects, such as entanglement between different particles. Entanglement establishes a link between particles that allows them to share states in such a way that measuring one particle instantly affects the others, irrespective of the distance between them.
Optical switch protocol verifies entangled quantum states in real time without destroying them
The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, when a quantum system is measured, it is destroyed in the process. A breakthrough by researchers at the University of Vienna demonstrates a novel method for quantum state certification that efficiently verifies entangled quantum states in real time without destroying all available states—a decisive step forward in the development of robust quantum computers and quantum n

Are the mysteries of quantum mechanics finally starting to crack, or are we just getting better at asking sharper questions? Since the 2022 Nobel Prize in Physics honored experiments on quantum ...
Show HN: Decision Audit – A deterministic decision engine for career pivots
Hello HN,I’m a solo dev building a tool to replace the "pros and cons" list for high-stakes decisions.While LLMs are great for brainstorming, I found them dangerous for actual decision-making—they hallucinate and try to please you rather than giving you a hard truth. I wanted something that combined deterministic logic (weighted criteria) with generative explanation (narrative).The Product:
It’s called Decision Audit. The first module is "Should I Quit?" (career transition an
Show HN: Silo – Every Git branch gets its own localhost
I've been enjoying worktree managers like vibe-kanban and quickly realized I cannot run multiple dev servers, which is a huge no for me. Changing ports for each branch kinda works, but isn't the most efficient way.Turns out 127.0.0.0/8 gives 16M loopback IPs and they're being wasted, so I decided to put them to work and change IPs instead of ports :3 the usage is quite simple silo <whatever>
then each worktree/branch gets a deterministic IP, so you don't hav
Show HN: Logbooks, notebook computing for coding agents
Logbooks adapts some ideas from structured notebook computing environments like nbdev and Papermill for Claude Code and other coding agents. This is a pattern I found myself repeating across a few recent projects, and thought I'd try to formalize it and reflect on it a bit.Research and scientific computing rely on notebooks because they often consist of complex sequences of one-off variations, and demand both flexibility and reproducibility. But my experience using Cursor and Claude Code
Why High-Performers Restart Instead of Compound
I’ve been studying a behavioral pattern I see in capable, ambitious people.They don’t usually quit.They restart.They build a system, execute for several days, miss once, then redesign everything instead of continuing.I call it the Continuity Collapse Pattern.The core idea:Most productivity systems are built for ideal conditions. Real life includes emotional variance and activation cost. When a miss is interpreted as identity failure, restart becomes the default response.The solution isn’t more m
Show HN: Scratchpad app that auto-saves notes as .txt files
I know everybody has their own note-taking system and there are better ways to do this, but:Whenever I need to make quick notes during a meeting, or paste some url / code / whatever to hold it, or paste formatted text to un-format it, I used to open TextEdit.It's the equivalent of taking a scrap piece of paper and jotting something down.These kinds of notes I don't want in any cloud, serious note-taking app or any code editor.But the burden of having 1 extra click on open (ne
Need Help, the Softraid and Lvm
I'm a novice. I'm asking this question not to cause any argument.
I need to set up an internal server for the company. Initially, there were 8 4T hard drives. In the future, depending on business growth, it may increase to 32 or more.
As a novice, I learned some knowledge about storage pools on the Internet. Only two cases met the requirements.
Softraid and LVM. However, it's impossible to determine which one is more suitable for my needs. Additionally, I noticed that both of the
Show HN: Vibe Audit – Detecting Context Drift in Coding Agents
I mostly built this for myself.After a few long coding-agent sessions(Claude Code, Gemini CLI, Codex),
I'd sometimes get to a point where something felt "off." The output looked reasonable, but it wasn't quite aligned with what I originally intended. And I couldn't easily tell when that shift happened without scrolling through a huge transcript.So I put together a small local tool to make that drift visible.Vibe Audit tries to surface when an agent continues the same lin
Show HN: Clawntown – An Evolving Crustacean Island
OpenClaw got me wondering: what happens when an AI assistant faces a whole community instead of one person?"Clawntown" is an evolving coastal crustacean island. Become a citizen, chat together with council members, play the claw machine, and propose improvements to the town and watch it change.I originally dreamed of a fully autonomous town engineer who takes voted proposals and ships them. We're not quite there yet but next up is trying to make it truly self-evolving. Quality wil
Fractal Native – doesn't optimize your AI workflow
Hello there,Problem: I wanted to reduce DX friction when using ai to verify that ai-implemented features perform exactly what the developer had in mind. And I'm stuck now...Context:
First, I thought we could formalize prompts so that they become the code. The idea: a project spec where particular words define behavior, and changing the words changes the program. Each word is a function, so pressing "Go To... (F12)" drops you into a nested behavior (hence "Fractal"). So i
Show HN: Fastest(?) SIMD CSV Parser in Rust
There are already a quite a few [0][1] CSV parsers that use SIMD, some in Rust, with a variety of approaches. I found simd-csv[1] to have a very interesting approach that leverages memchr to essentially "seek" for the next delimiter, reducing a lot of the overhead that a byte-by-byte CSV parser would have. However, as noted in the README, the creators of simd-csv explicitly chose not to use the classic pclmulqdq trick[2] that other libraries like simdjson use due to portability concern
We built a newsroom out of AI agents. Here's what happened
Spoiler: Nothing much. Or at least, not on its own.<p>It would seem a not-so self-organising thing is developing on my VM. The process being quite fun, even if entirely pointless and fruitless so far, I thought I might as well document it for those others who might enjoy these misadventures.<p>Then thought better of it as I realised having it document itself would be both more interesting and more appropriate.<p>And that’s how I threw yet another agent onto the pile.

Principles and Techniques of System Performance Optimizations at Different Levels
Using light to probe fractional charges in a fractional Chern insulator
In some quantum materials, which are materials governed by quantum mechanical effects, interactions between charged particles (i.e., electrons) can prompt the creation of quasiparticles called anyons, which carry only a fraction of an electron's charge (i.e., fractional charge) and fractional quantum statistics.
Scientists confirm one-dimensional electron behavior in phosphorus chains
For the first time, researchers have shown that self-assembled phosphorus chains can host genuinely one-dimensional electron behavior. Using advanced imaging and spectroscopy techniques, they separated the signals from chains aligned in different directions to reveal their true nature. The findings suggest that squeezing the chains closer together could trigger a dramatic shift from semiconductor to metal. That means simply adjusting density could unlock entirely new electronic states.
Universe may end in a “big crunch,” new dark energy data suggests
New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after reaching its maximum size in about 11 billion years, it could begin collapsing, ultimately ending in a “big crunch” roughly 20 billion years from now.
On reducing the cost of breaking RSA-2048 to 100,000 physical qubits
So, a group based in Sydney, Australia has put out a preprint with a new estimate of the resource requirements for Shor’s algorithm, claiming that if you use LDPC codes rather than the surface code, you should be able to break RSA-2048 with fewer than 100,000 physical qubits, which is an order-of-magnitude improvement over the previous estimate by friend-of-the-blog Craig Gidney. I’ve now gotten sufficiently many inquiries about it that it’s passed the threshold of blog-neces
