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
AI System – Is It Your "Cognitive Exoskeleton" or Simply Your Super-Fast Intern?
As it turned out, about "AI" there are two completely different understandings of the term "cognitive exoskeleton"...1. The Generalized-Abstract UnderstandingWell, it's clear that there is a generalized-abstract concept: you create text faster, translate faster, format faster, program faster, create reports and reviews faster...2. The More Concrete UnderstandingThere is a more concrete concept, when you for your typical mental activity create all kinds of ensembles from
Quantum Teleportation Breakthrough Sends 5 States at Once
A team in China has demonstrated the simultaneous teleportation of multiple sideband qumodes in a continuous-variable system, overcoming a longstanding technical barrier.
Show HN: Idea-reality-MCP – MCP server that searches real data before you build
I kept wasting hours building things that already existed. Asked Claude to help me build a food delivery app — searched GitHub afterward, found 847 similar repos with 12 competitors over 1k stars. 6 hours wasted.So I built an MCP server that does the searching before you write code. It scans 5 real-time sources (GitHub, Hacker News, npm, PyPI, Product Hunt) and returns a quantified reality_signal (0-100) with actual evidence — repo counts, star counts, top competitors, and pivot suggestions.Exam
Ask HN: How to best use time before starting a SWE job?
I'm completing my fourth year in college and have accepted a SWE offer at quant firm, starting in the summer.I've been agonizing a lot over how to best spend my time. I've considered reading books (DDIA, for example), diving deeper into CS fields (college always felt a bit too shallow/meaningless to me), or learning more about C++/Rust/other languages. Clearly, I'm suffering a bit of analysis paralysis right now, and I would appreciate some advice on what to d
Show HN: QF STEM Ledger – Logging Structured Cognitive Work
I built a tool to log structured cognitive work, including proofs rebuilt from first principles, research notes drafted, and concepts properly mastered, after noticing that serious technical effort is rarely recorded in any structured way.<p>Curious to hear what HN thinks.
Tell HN: Coherence Doesn't Scale
Since quitting my software engineering job in November because my boss was pushing reckless use of AI, I've spent a ton of time trying to figure out what place AI actually has in the future economy.Thanks in large part to some amazing Substack authors[0,1] as well as the fact that agentic engineering is in the process of rediscovering everything that we have learned about human delegation, I finally had a breakthrough: coherence doesn't scale.A ton of energy has been & will be expe
Show HN: Focido – mobile app where real people motivate you to finish tasks
I've been struggling with my own to-do lists for years. Apps like Todoist or Habitica are great for reminders, but they never quite push me over the edge when motivation dips. So I built Focido: a social to-do app where you hire actual humans as motivators.Here's how it works. You post a task – say, "Run 5km tomorrow" or "Finish that report by Friday" – and pick a motivator from the marketplace. They check in via chat, nudge you with encouragement (or gentle guilt),
Show HN: JSON Maps – Describe Maps as JSON, Render Them with React and MapLibre
I have been building a library that lets you define interactive maps as a JSON object. Now the already existing Maplibre Spec is quite strong, but every time I needed to put a map together with markers, widgets, a legend, layer controls and a nice color palette, I'd end up writing a lot of boilerplate html, Even writing with AI it would mess up the layer management and working with different kind of formats, So I started building a layer on top. Its inspired by the json-render library by ve
My journey from a todo app to a VM where tasks are stateful executable programs
# How it all started?Sometimes, there are moments when you feel loosing control over your life, when there is to much on a plate and all this overwhelms you, makes you anxious.
For me, solution always was to use kind of "get things done" tools, to organize myself. I tried various todo apps, even bought a paper todo, but this wasn't enough this time. Every restriction in functionality, every missed feature made me feel I'm loosing control again.
And one moment I gave up and d
Show HN: Agentplace, the tool we built to become a 20x company
Garry Tan posted a video this week about what he calls 20x companies. The idea is that small teams beat incumbents many times their size by automating everything internally, not just one or two functions. This alpha is real, and I think it is underhyped tbh.But here's the honest part, building agents is hard, expensive and most of the scaffolding we make would be obsolete with a new labs release. at the same time models are not quite there and they are not keeping up with "coding is de
Ask HN: Why do so many digital banks have such unreliable APIs?
I have for years synced all my financial data through aggregators (Mint for a long time until it was shut down, YNAB for a bit, Monarch Money now, and have experimented with a dozen others along the way). I probably have 20 accounts across credit cards, bank accounts, investment accounts (traditional and crypto), retirement accounts, and others (HSA, transit/commuter card).Something I have anecdotally noticed is that the institutions that struggle the most (whether initial connection setup,
Show HN: mvntSTUDIO – AI model that generates dance choreography from music
I think Suno opened up music. Kling and Runway opened up video - but there's one creative domain nobody has touched yet: dance.So my team built an web app — give it a YouTube link to your music and it generates a 3D dance animation in under 2 minutes. The core is a diffusion-based music-to-motion model (mvnt-m4) trained on proprietary mocap/label data from professional choreographers.I think dance is the missing piece of AI-generated content — just like how performance made K-pop a glo
Show HN: DiagramIDE – a Rust GUI to Compose Diagrams via Tcl, Prolog, and Pikchr
I built DiagramIDE because I wanted a more modular way to handle diagramming-as-code. It’s a Rust-based GUI (EGUI) where you can split logic, data, and rendering into separate windows. Instead of one giant DSL file, you can script components in Tcl, define relationships in Prolog, and pipe the results into Pikchr for the final render.Fair warning: it’s an early alpha and still quite rough around the edges. I’ve been dogfooding it for my own work so it’s definitely functional but expect unexpecte
Show HN: High Tech Before/After Cleaning Gallery
My apartment is a mess. Between day work, kids and all the side projects cleaning is the thing that usually takes the back air. It’s embarrassing really, I can come up with a sophisticated tech strategy, find the right words to say to an employee who’s down and I can’t seem to fold the laundry when I take it out of the dryer. I’m a developer by heart, so after a little bit of self pity, I decided that my daughters are to blame for the mess and thus dug head deep into debugging the problem ans re
Ask HN: How do I use AI as a tool if some answers are objectivity incorrect?
I'm really at stump here, I want to use AI to make my life easier with work but how do I if I can't trust its answers 100% of the time? I mean I understand it needs human intervention but if I don't know the answer itself, it involves me stopping at the exact time I need to, searching for the correct answer elsewhere entirely and or just giving up on it, its quite exhausting.The process for me is usually I go down a path with an LLM; I get excited at the prospect of using it as a
Dynamical freezing can protect quantum information for near-cosmic timescales
Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information loss. Physicists have long known of a strange exception, called dynamical freezing, when quantum systems shaken at precisely tuned frequencies evade these laws. But how long can this phenomenon postpone thermodynamics?
Sparks of Genius to Flashes of Idiocy: How to Solve AI’s ‘Jagged Intelligence’ Problem
We need to give models knowledge that anchors their behavior to the realities of our world. Modern AI chatbots can do amazing things, from writing research papers to composing Shakespearian sonnets about your cat. But amid the sparks of genius, there are flashes of idiocy. Time and again, the large language models, or LLMs, behind today’s generative AI tools make basic errors—from failing to solve basic high school math problems to stumbling over the rules of Connect Four.This instability has be
Putting sports stats to the test: Unpredictable play helps pick a winner in soccer
A comprehensive game plan and strategic tactics are critical to winning soccer, but how much does a team's unpredictability in moving the soccer ball around the pitch matter? In a new article published in PLOS One, an international team of researchers analyzed event data from top-tier association soccer competitions to provide insights into match analysis, player tactics and game strategy.
