1Business books are entertainment, not strategic tools
- Popular business books often prioritize emotional appeal over intellectual depth, offering simplified narratives and generic advice rather than practical insights. True business success comes from understanding complex realities, making informed decisions, and focusing on operational mastery rather than motivational mantras.
Business books as entertainment
Most business books stretch simple ideas into lengthy narratives for entertainment value. While they may contain useful insights, they primarily serve as entertainment rather than practical guides, with key concepts often reducible to a few pages.Value of learning through stories
Stories and narratives help concepts stick better than pure theory. While core ideas can be simple, narratives provide context and help readers internalize lessons through examples and repetition.Reading recommendations
Many suggest reading narrative non-fiction and shareholder letters over traditional business books. Books like Barbarians at the Gate, When Genius Failed, and Bad Blood offer both entertainment and business insights.

721 GB/s CSV Parsing Using SIMD on AMD 9950X
- The article discusses the release of Sep 0.10.0 in April 2025, which achieved significant performance improvements for CSV parsing, reaching 21 GB/s on AMD 9950X CPUs with AVX-512 support. The update reflects ongoing optimization efforts that have resulted in a 3x performance boost since the software's introduction in June 2023, demonstrating how software and hardware improvements can work together to enhance processing speeds.
Intel's AVX-512 removal
