Ask HN: What marketing book helped you become a better marketer?

Hacker News - Sat, 04/05/2025 - 1:45am

Hi HN,

There are so many marketing books out there, but most of them feel repetitive or not very practical.

I’m interested in book recommendations that helped you learn marketing and apply it effectively. Whether they're about growing a business, building an audience, or enhancing branding, I’d love to hear your suggestions.

What books made a real difference in how you do marketing?

Thanks!

Show HN: Corral – A Visual Logic Puzzle About Enclosing Numbers

Hacker News - Sat, 04/05/2025 - 1:33am

Hey HN!

I just finished building a puzzle game called Corral, and I’d love to share it with you. It’s a logic puzzle played on a rectangular grid, where some of the cells contain numbers. Your goal is to mark which cells are inside a single continuous loop that encloses all the numbers.

For each numbered cell, the number tells you how many cells are visible in the four orthogonal directions (up, down, left, right) until a wall of the loop is hit, plus the cell itself. So a cell with a 2 must see one empty cell before hitting the loop boundary. Gameplay is all about deduction: you can mark cells as definitely inside or definitely outside the loop. The loop must be one continuous shape, with no "islands" inside. Every puzzle has a solution and can be solved using pure logic.

There are three difficulty levels that you can choose from, enjoy!

Would love to hear your thoughts, ideas, or bug reports. Thanks for taking a look!

Show HN: OCR pipeline for ML training (tables, diagrams, math, multilingual)

Hacker News - Sat, 04/05/2025 - 1:22am

Hi HN,

I’ve been working on an OCR pipeline specifically optimized for machine learning dataset preparation. It’s designed to process complex academic materials — including math formulas, tables, figures, and multilingual text — and output clean, structured formats like JSON and Markdown.

Some features: • Multi-stage OCR combining DocLayout-YOLO, Google Vision, MathPix, and Gemini Pro Vision • Extracts and understands diagrams, tables, LaTeX-style math, and multilingual text (Japanese/Korean/English) • Highly tuned for ML training pipelines, including dataset generation and preprocessing for RAG or fine-tuning tasks

Sample outputs and real exam-based examples are included (EJU Biology, UTokyo Math, etc.) Would love to hear any feedback or ideas for improvement.
