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: Open-Source Finance Agent
Hey guys,I’m open sourcing an autonomous financial research and analysis agent. The agent can search SEC filings, extract key financials, and build financial models.It’s scored 80% on the public Finance Agent validation set with GPT-5, compared to the top result of 55% listed on their website for their private validation set.But, their public validation set has mistakes. There are quite a few cases where the “ground truth” answers in the benchmark are wrong. I’ve documented each case with citati
Ask HN: Anyone pivoted from SWE/mgmt to a different career in your 30/40s+?
Having been coding for nearly 25 years now and being in engineering management for the past couple of years (still actively coding 30-50% of my time), I'm feeling increasingly tired of tech. Software development, more specifically. I'm quite capable of both producing software myself _and_ managing teams producing software.Have you pivoted from software engineering/engineering management into a different career altogether in your 30s, 40s or beyond? I'm keen to hear your story
Show HN: A better Hacker News front end
I forked pajecawav's better-hn repo, which turned out to be an excellent foundation to build on. While the original implementation was clean and functional, it didn't quite capture the essence of Hackernews. More importantly, it was missing some features I considered essential for a truly viable alternative.After tinkering with it for a while, I think I've nailed it—at least for my own use case. If it works well for me, chances are others might find it useful too. So I figured, wh
Ask HN: How do I get a job in OS and networks as a new grad?
I'm about to graduate college. Since the middle of high school to now: I've worked on lots of C and Rust, reverse engineering GPU drivers and hardware for phones (and toying with Linux drivers), low-latency video streaming, am writing my own OS (but need to apply to stuff before that's fleshed out), and have read quite a lot of research papers in networking. I know what a TCAM is, I know what flows are, I know that NICs DMA packets to ringbuffers in host memory, and I know that th
Show HN: HN Terminal Theme Browser Extension
HN is ugly so I wanted to change that. I am quite aware that this is a common and amateur project but I couldn't find a decent HN theme online.
I am not putting this on the Chrome Web Store.
Do whatever you want with this.
Show HN: Hokusai Pocket (WIP) – Portable GUIs with MRuby
Whassup?,A couple years ago, I started a project for easily authoring GUIs with Ruby. The project is named Hokusai.
It features the ability to compose reactive UI components with events and props, and uses a unique-ish template language.More information on Hokusai can be found here: https://hokusai.skinnyjames.net/Since then I've worked on Hokusai Native (https://github.com/skinnyjames/hokusai-native-builder/), which compiles a GraalVM native image &#
Ask HN: What are some impressive vibe coding projects?
I'm looking to create a list of projects that people have had success with, whether they are personal projects that have no financial incentive or projects that have made money.<p>I'm also looking for videos that document the project from start to finish. The youtube algorithm makes these videos quite difficult to find.
Show HN: I got tired of managing dev environments, so I built ServBay
Hey HN,For years, my local development setup has been a fragile mess of tools that never quite played nicely together. On my mac, it was a constant battle with Homebrew services starting (or not starting) on boot, conflicting PHP and Node versions managed by `asdf` or `nvm`, and a collection of `docker-compose.yml` files that I'd copy-paste and tweak for every single project. The cognitive load was just too high.Setting up SSL was another chore involving `mkcert`. Sharing a quick demo with

2D devices have hidden cavities that can modify electronic behavior
In the right combinations and conditions, two-dimensional materials can host intriguing and potentially valuable quantum phases, like superconductivity and unique forms of magnetism. Why they occur, and how they can be controlled, is of considerable interest among physicists and engineers. Research published in Nature Physics reveals a previously hidden feature that could explain how and why enigmatic quantum phases emerge.

Show HN: I scraped Reddit to find the most controversial chef knife
I wanted to quantify the endless "which knife should I buy" debates on r/chefknives, so I built a data analysis pipeline to get some real answers.The project is a 5-phase system built with Node.js. It first uses Fuse.js for fast, typo-tolerant fuzzy matching of ~450 known brands and ~8,700 models. The remaining text is then passed to an LLM (via OpenRouter) for discovering new, unknown entities and performing sentiment analysis on every mention. I ran it on over 1,000 threads, tot
Astronomers discover a gigantic bridge of gas connecting two galaxies
Researchers from The University of Western Australia node at the International Centre for Radio Astronomy Research (ICRAR) have uncovered a colossal bridge of neutral hydrogen gas linking two dwarf galaxies, which spans an astonishing 185,000 light-years between galaxies NGC 4532 and DDO 137, located 53 million light-years from Earth.
A clue to ancient life? What scientists found inside Mars’ frozen vortex
Mars’ north polar vortex locks its atmosphere in extreme cold and darkness, freezing out water vapor and triggering a dramatic rise in ozone. Scientists found that the lack of sunlight and moisture lets ozone build up unchecked. This discovery, made with data from ESA’s and NASA’s orbiters, could reveal clues about Mars’ past atmospheric chemistry and potential for life.
This tiny laser could transform how we see and sense the world
Researchers from NTNU and EPFL have unveiled a compact, low-cost laser that outperforms current models in speed, control, and precision. Built using microchip technology, it can be mass-produced for use in everything from Lidar navigation to gas detection. The design’s stability and easy frequency tuning could transform communication and sensing technologies.
Simplified Sachdev-Ye-Kitaev model simulated on trapped-ion quantum computer
The simulation of strongly interacting many-body systems is a key objective of quantum physics research, as it can help to test the predictions of physics theories and yield new valuable insight. Researchers at Quantinuum, a quantum computing company, recently simulated a simplified version of a well-known theoretical model, the so-called Sachdev-Ye-Kitaev (SYK) model, using a trapped-ion quantum computer and a previously introduced randomized quantum algorithm.
