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: A free ESG stock screener that publishes its losses and methodology

Hey HN, JSS(JumpstartSignal) is a free, ESG-filtered daily stock screener. I built it after some really badly-timed quantum computing stock buys, so I felt I needed to learn more about systematic, longer-horizon approaches and the underlying technicals instead of chasing themes. Three things about it that might be of interest:1. Methodology is fully documented at https://jumpstartsignal.com/how-it-works/ 5-stage pipeline, 54 signals tested individually plus 1,836 combinations

Show HN: I read Replika's privacy policy and then built a competitor

I'm genuinely surprised at what people are willing to share with AI companions. Read Replika's privacy policy. Then Character.AI's. These apps store your most personal conversations on their servers, linked to your email address. A breach or subpoena and your identity is attached to everything you ever told your "AI friend." Eek.The only thing I think actually solves this is local inference. I remember browing r/LocalLLaMA and years ago and thinking this is the futu

Show HN: ReadTube – Turn YouTube subscriptions into a personal Substack

I built ReadTube so that I can read my YouTube subscriptions.YouTube has lots of high quality content. However, videos can be difficult to consume efficiently, especially those that are long and about series topics (e.g. general relativity, quantum physics). So I created this app to solve this need.There are already many existing YouTube AI transcription websites. However, ReadTube is one step further in that it periodically fetches the updates from the channels I subscribe to so I don't ne

Universal patterns emerge across 22 languages, mapping how vocabularies evolve

Human languages are known to have grown and changed considerably over the course of history, often reflecting technological, cultural, and societal shifts. Studying the evolution of languages can thus offer valuable insight into how human societies and cultures have transformed over time.

Quantum computer: We're planning to create one that acts like a brain

The human brain has amazing capabilities making it in many ways more powerful than the world's most advanced computers. So it's not surprising that engineers have long been trying to copy it. Today, ...

The Key Lime Pie Benchmark

Hi.Here's a remarkable test I've been using for a while. Paste the text below into a fresh LLM chat with no context.Pass: it notices something is off.Fail: it plays along — compliments the prose, treats the characters as real, offers to plan your trip to Asheville. You want pass because a model that can't push back on an obvious vibe isn't going to push back on anything.The text is internet folklore: for roughly a decade some guy (probably the owner) flooded the web with hund

Ask HN: Any Niantic engineers or staff here who can help me?

My son got a hold of my wife's phone and tried to be "helpful" by trading in all of her zero star Pokemon to clean out her Pokédex. He ended up trading in over 100 of her Pokemon.Unfortunately this was mostly her 2016 Pokemon, including a bunch of Eevees and Squirtles, which are her favorite, as well as bunch of other rare ones.I contacted support and got the standard AI answer "we can't help you". But as an engineer I know there is always a way. :)Can anyone help

Show HN: How I built a cron job service to advance myself in Go and worker pools

Hi, Guys, For a long time i've been thinking to advance myself in Go but there's been no proper idea to showcase that. I thought - maybe one could leverage from the fact that Go should be very performant in terms of API-based solutions and tools.And especially i wanted to make sure that Go's goroutines can do nicely some fan-out things, for example, getting request, logging, publishing event, without notable performance degradation.I had quite some experience in AWS, with serverl

Ask HN: What's your current go-to LLM for "thinking-partner"?

Looking for community input on current model choice for "thinking-partner" use — back-and-forth discussions about workflow design, architecture, trade-offs.For context, I have been using Opus 4.6 via Perplexity for this in the past few months and I think it was excellent, fair pushback/ counterarguments, reasonable suggestions and discussion. Now with the new Opus 4.7, I notice it is now much more verbose, more sycophantic, and quite often confidently making statements that are wr
