🥇 商业智能的垃圾
Investigating three real-world incidents in our cybersecurity evaluations — simonwillison.net · 07-30 23:41 · 🤖 AI / ML
许多公司在未明确问题前就购买昂贵的商业智能（BI）工具，之后为了证明预算合理性而强行使用，导致工具实际使用率极低。财务团队会轻易砍掉不流行的工具，但那些高价工具却因沉没成本而难以舍弃。这种“为用而用”的做法不仅浪费资源，还掩盖了真正的业务需求。作者指出，工具的价值应基于解决实际问题，而非证明采购决策正确。
💡 为什么值得读: 直击企业软件采购中的常见误区，提醒读者避免陷入“先买工具再找问题”的陷阱。
🏷️ GPT-2, weights, bugfix, training

llm 0.32rc2 — simonwillison.net · 07-30 22:52 · 🤖 AI / ML
本系列探讨如何在C++/WinRT中实现支持跨线程调用的敏捷（agile）Windows Runtime委托。前几部分介绍了多种实现方案及其权衡，本部分作为系列终章，指出某些细节可能并不重要。作者强调，在特定场景下，过度追求完美敏捷性反而增加复杂性，开发者应根据实际需求选择合适方案。
💡 为什么值得读: 为C++/WinRT开发者提供敏捷委托实现的完整指南，并给出实用的简化建议。

Pluralistic: The stupidest imaginable excuses for surveillance pricing (30 Jul 2026) — pluralistic.net · 07-30 12:51 · 🔒 安全
作者发现自己的GPT-2风格模型在指令遵循评估上显著落后于OpenAI的原始权重，为此展开系统性排查。在第一部分分析可能原因后，本部分揭示了一个关键bug：训练数据预处理中的错误导致模型无法正确理解指令。修复该bug后，模型性能大幅提升，接近OpenAI的基线。作者还分享了使用AI辅助检查文章的技术细节。
💡 为什么值得读: 通过真实案例展示GPT-2模型复现中的常见陷阱及调试方法，对训练类似模型的研究者极具参考价值。
