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
Porting an INT8 VHDL CNN from Intel Agilex 3 to Lattice Certus-NX
We implemented a small INT8 CNN for handwritten digit classification (NIST SD19 subset) in pure VHDL and built it on two different FPGA families: Intel Agilex 3 and Lattice Certus-NX.The design was originally targeting Agilex 3. We later rebuilt it for a Certus-NX board to see how portable the RTL actually was and what changed in terms of resource usage and timing.## ModelInput: 128×128 grayscale images streamed over UART from a host PC webcam.Architecture:
- 3×3 conv (8 filters) + pooling
- 3×3
Show HN: Running an LLM Inside Scratch
This runs the smallest llama2.c checkpoint (stories260K) inside Scratch/TurboWarp by compiling C inference code into Scratch blocks using llvm2scratch. The model is quantized to Q8_0 and packed into Scratch lists. If everything works, the sprite streams "Once upon a time..." token-by-token into its speech bubble.I started this as an experiment in how far Scratch's VM could be pushed, and because the idea of running an LLM inside Scratch felt absurd and fun. The main challenge
Show HN: Promptscout a local prompt enricher for Claude Code
I use Claude Code daily and got tired of repeatedly listing relevant files in prompts. So I built promptscout: a small local tool that takes your prompt + repo file tree and enriches the prompt with the most relevant files/paths, so Claude has a better starting point.<p>It uses a quantized Qwen 3 4B model and runs fully on your machine. I also added a Claude Code plugin via UserPromptSubmit that calls the CLI and swaps in the enriched prompt before the request goes to Claude.
Exercise rewires the brain — boosting the body’s endurance

“My Optimistic Vision for 2050”
The following are prepared remarks that I delivered by Zoom to a student group at my old stomping-grounds of MIT, and which I thought might interest others (even though much of it will be familiar to Shtetl-Optimized regulars). The students asked me to share my “optimistic vision” for the year 2050, so I did my best to oblige. A freewheeling discussion then followed, as a different freewheeling discussion can now follow in the comments section.I was asked to share my optimistic vis
Show HN: Consciousness Gateway – AI routing with consciousness-first alignment
I built a self-hosted AI gateway that implements all 3 layers of
the GATO alignment framework (Model, Agent, Network) using
consciousness-aware routing based on Donald Hoffman's conscious
agent theory.What makes it different from standard gateways:1. Product Algebra routing (Kronecker fusion) selects models based
on cross-modal interaction patterns, not just cost/capability2. Dharma constraints (no-self regularization, entropy optimization,
mindfulness, compassion) are built
Time crystals could be used to build accurate quantum clocks
Once considered an oddity of quantum physics, time crystals could be a good building block for accurate clocks and sensors, according to new calculations

Show HN: IQT – Why space feels panoramic and time feels fleeting
I've spent the past year building a theory of phenomenal experience (consciousness) that's designed to be falsifiable.It identifies phenomenal quality with a specific mathematical object (the algebra-state pair on a causal diamond in algebraic quantum field theory) and derives three experimental protocols with pre-registered failure conditions.The short version: take the "intrinsic nature" intuition from Russellian monism seriously, ask what mathematical object could play tha
Show HN: The "Vat of Fluid" Model–Solving 7Systems Paradoxes ViaFirst Principles
I have no formal background in physics, macroeconomics, or philosophy. For the past 44 days, I have been stripping away "legacy data" to rebuild my internal processing (my "Native OS"). During this time, I developed a singular mental model I call the "Vat of Fluid."
The core premise: Every complex system—from traffic to quantum entanglement—is a contained volume of information. Stagnation (perfection) leads to system failure. Fluidity (stochasticity/chaos) is
Show HN: Detecting coordinated financial narratives with embeddings and AVX2
I built an open-source system called Horaculo that analyzes coordination and divergence across financial news sources.
The goal is to quantify narrative alignment, entropy shifts, and historical source reliability.

Extract claims (NLP preprocessing)
Generate sentence embeddings (HuggingFace)
Compute cosine similarity in C++ (AVX2 + INT8 quantization)
Cluster narratives
Compute entropy + coordination metrics

Show HN: Migrate away from Vue SFC's to native TSX
I've been actively using Vue for my official and personal projects for over 6 years now. While SFC was great it's quickly becoming a pain. It requires custom Volar plugins. It doesn't work with native typescript. The vue-tsc overrides "fs" imports just to be able to detect and run vue files.I am not sure why Vue doesn't talk more about native TSX support because it eliminates this whole class of issues. In my work project, this has been a major pain because vue-tsc
Show HN: Alertmouse – a free, better version of Google Alerts
Built this tool as a personal passion/side project last year along with a couple Seattle friends. It's now got 3K+ folks tracking their name/brand/interests for free and ~150 paying subs, too. Not quite breakeven yet, but close (though none of us are getting paid ¯\_(ツ)_/¯). Suspect it might be useful/interesting to some of y'all.
Show HN: Accountify – habit tracking with visible accountability
I built a small MVP because I kept quitting habit apps the same way: silently.Most tools optimize for motivation, streaks, or reminders.
I wanted to test a different angle — social accountability.Accountify centers habits around small groups:
– shared habits
– automatic check-ins
– messages and photos as proof
– visibility when you miss a dayThe idea is simple: quitting shouldn’t be invisible.Tech-wise it’s a straightforward Next.js + Supabase app.
