Lean

Introduction In a world saturated with buzzwords like “growth hacking,” “scale‑up,” and “unicorn,” a quieter, more intentional movement is gaining traction: minimalist entrepreneurship. Unlike the traditional image of the entrepreneur who chases endless funding rounds, hires massive teams, and piles on features, the minimalist entrepreneur deliberately strips away excess to focus on what truly matters—value, sustainability, and personal freedom. This article dives deep into the philosophy, practical tactics, real‑world examples, and common pitfalls of building a business with a minimalist mindset. Whether you’re a seasoned founder feeling burnt out, a side‑hustler looking to turn an idea into a lean venture, or simply curious about how less can be more, you’ll find actionable insights to help you design a company that aligns with your values while still delivering impact. ...

SorryDB: Can AI Really Prove Real-World Math Theorems? Imagine you’re a mathematician knee-deep in a complex proof, but you hit a wall. Instead of giving up, you jot down a placeholder—“sorry, I’ll finish this later”—and move on. Now, picture AI stepping in to fill those gaps automatically. That’s the promise of SorryDB, a groundbreaking benchmark introduced in the paper “SorryDB: Can AI Provers Complete Real-World Lean Theorems?” (arXiv:2603.02668). This isn’t some abstract academic exercise; it’s a practical testbed pulling “sorry” statements from 78 real GitHub projects, challenging AI to prove theorems that actual mathematicians are working on. ...
