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: SLayer, a semantic layer maintained by your agent

Hello HN!If you want to connect your agent to a database (say, to build a data analyst chatbot or any kind of agentic app) today you have 2 options: an SQL MCP server or a semantic layer.SQL MCP is the easiest path to setup, especially if you also have a .md knowledge base which the agent can update. It gets quite messy quickly though, especially if there's many interactions or DB is large. Generated SQL is hard to review if you want to understand where the numbers came from, and related qu

Show HN: NodeDB – High Perfomance Multi-Model Database

Hey HN,I've been working on a multi-model database called NodeDB.Originally, i've found out the idea of SurrealDB quite good. However, it doesn't have some graph and vector features that I need. And since it is just a KV wrapper, instead of purpose-built engine, the performance will never be close to the specialized databases (like Neo4j, Pinecone, Clickhouse, etc).And i've asked myself, what if, there is a database that have the same idea, but built differently? Instead of j

Can you help reconcile my first/second-hand LLM Experience with HN's Experience?

I've made an account as a long-time lurker because I am hoping y'all could help reconcile my experience in my company/team with what seems to be the wise HN consensus around LLMs.My Background (Software Engineer II):I've been writing software professionally for >10 years and grew up coding games/websites for fun; did my undergraduate in C.S./C.E., and did some time in ML research and such. Right now I'm on the back-end/DevOps team - my teammates are all

The social contract between the user and the OS is broken

Here are just some of the social contract rules that have been reneged upon:* Hitting the X means close/quit the app.* Close/quit means end the task/program, not minimize it and run in the background.* Searching allows you to search for a file or a program quickly and directly.* No ads on an OS that the user paid for* Clicking "No" means stop asking, not "remind me later"* User's data should remain user's data* If a user backs up files to the cloud, i

Show HN: GIF Pile. a site to make piles of GIFs

I'm quite fond of obnoxious looking gifs in a post-ironic way as a manner of shitposting and or injecting humor into a chat. The issue with this however is that, for no real good reason at all, the simple usecase of "Have image/gif background, bombard with garbage" had no real good tooling.There's gif editors out there, EZgif my beloved is probably my most used non-search-indexing-slash-social-media-site, but they're kinda clunky for my specific usecase of making di

Ask HN: Is Spam getting worse or is Gmail getting worse?

Over the past couple of months I've noticed that number of spam emails landing in my inbox has increased by quite a bit. I keep a very tidy inbox, so it's pretty easy for me to notice them and mark them as spam. But I'm curious: is Google just getting worse at detecting spam, or is the spam somehow evolving?For example, I just got this email:Sender: [email protected] Subject: the wagon is inThe body contains tons of literal HTML tags that weren't parsed

Show HN: Recursant, a mesh-based control plane for AI agents

I have submitted before, but it didn’t end up in the Show HN list for some reason.I have built Recursant, an AI agent governance platform that governs agents across stacks and clouds to maintain compliance. In many large enterprises this is a real compliance issue with different teams using different frameworks and runtime environments, which creates control risk.I hope to get some feedback on it. It is a viable alternative to the large vendor controlled stacks. Architecturally it is quite uniqu

Show HN: I made a screen recording app to make demos like an Apple commercial

Hey HN!I made ShotGlass, a Mac app for screenshots, screen recordings, and cinematic demos.I was tired of jumping between four apps to make one product demo. Screenshots, recordings, annotations, and After Effects for anything cinematic.I also saw the MacBook Neo commercials (recording playing on a 3D MacBook in a scene) and wondered why no screen recorder just did that.So ShotGlass does all of it: multi-window capture, annotations, zooms, transitions, and dropping a recording onto a 3D MacBook

These Seven AI Rings Translate Sign Language in Real Time

The wireless rings read 100 common signs from two sign languages and “autocomplete” sentences. At the turn of the 20th century, William Hoy transformed Major League Baseball. The most prominent deaf player in history, he taught his team American Sign Language (ASL) to communicate on the field while keeping opponents in the dark. His silent speech, a legacy well over a century old now, also inspired umpires to make calls using hand gestures.ASL is one of some 300 sign languages used t

A new way to spot signs of dark matter

Dark matter is thought to make up most of the matter in the universe, but the only way it interacts with its surroundings is through gravity. If two colliding black holes spiral through a dense region of dark matter and merge, gravitational waves rippling across space and time could carry an imprint of that dark matter.Now, physicists may be able to spot such imprints of dark matter in gravitational waves that are detected on Earth. Researchers at MIT and in Europe have developed a method t

Method for measuring energy amounts less than a trillionth of a billionth of a joule could boost quantum computing

The fundamentals of quantum mechanics are minuscule. Scientists constantly home in on finer resolutions to measure, quantify, and control these fundamentals, like photons that carry light and have no mass unless they are moving. The more precise the measurement, the more possibilities for better quantum technology or the ability to detect elusive dark-matter axions in deep space.
