Inspired by 3Blue1Brown's Wordle video I applied maximum entropy to Mastermind.

The solver averages 4.42 guesses across all 1296 possible codes.

Includes an interactive game where you can see the optimal next move.

That's fair. It's just a suggestion - it's been useful for me in early stages of UI prototyping.

Nice project!

This pairs nicely with ASCII-Driven Development - for iterating and modifying layouts with AI.

Hi HN, I built a chess position recognition system that runs entirely in the browser.

The project walks through the full pipeline: manually collecting data from book scans, comparing Autoencoders vs. SimCLR for representation learning, and deploying with ONNX Runtime and Pyodide to avoid server costs.

The included demo recognizes board diagrams and generates Lichess links for analysis.

Nice project! One small suggestion, adding a search or category filter would help simplify navigation given the number of calculators available.

Nice touch - seeing the Windows 95 IE favicon took me back for a while.

Seems like reading the code is now the real work. AI writes PRs instantly but reviewing them still takes time. Everything flipped. Expect more projects to follow - maintainers can just use ai themselves without needing external contributions.

Show HN: Why Neural Networks Need He Init, Clipping, and Momentum

sbondaryev — Thu, 15 Jan 2026 14:12:49 +0000

Hi HN,

I made an interactive guide showing why neural networks need specific training techniques.

Start with a simple network trying to learn x². Each section introduces a problem like gradient explosion or dead neurons and shows the fix that solves it using ReLU activation, He initialization, gradient clipping, and momentum.

All code is editable and runs in the browser.

Nice visualization of the residual connections. Is the animated svg manually created or programmatically generated? What tools did you use?

I'm working on interactive explorations of algorithms and machine learning. Small, visual, hands-on demos that help build intuition by letting people tweak code/parameters and see how things behave in real time.

This looks promising - I've always found the schema duplication annoying with Zod/Yup. Would be great to see benchmarks vs Typia/ArkType at https://moltar.github.io/typescript-runtime-type-benchmarks/

Great idea, thanks for sharing! Tried your prompts with ChatGPT and Claude than iterated on it. The ASCII doesn't render perfectly in the web interface but looks good when copy/pasted into a text editor. Key benefit: I used to iterate on layout by generating HTML+Tailwind directly, which burns tokens fast. This ASCII approach lets you nail the structure first without the token cost. Much better for free tier usage. Appreciate the writeup!

It really depends on your level - this kind of graphics work is usually learned over many years.

You can also find some insight into his work process here: https://x.com/BCiechanowski/status/1387827101294686210?s=20

Most people doing this level of work built their own tools over time, learned a bit here and there, and kept refining things throughout their career.

Nice project! I'm not very strong at note recognition, so I see the “Wrong note” message quite often (which is totally fine), but the frequent blinking feels a bit distracting. You might consider making the feedback a little less visually intense.

I like this book. The probability section is great, especially how they handle the Monty Hall paradox. They use "four step method" that breaks it down perfectly - way clearer than the explanations you get in movies like 21 or numb3rs.
