AI Worming through Word — simonwillison.net · 19h ago · 🔒 Security
Håkon Måløy discovered a novel prompt injection variant that enables self-replicating worms in Microsoft Word using Copilot. This attack involves an attacker embedding hidden instructions within a document, which Copilot for Word then misinterprets as part of a user’s request. This allows the malicious instructions to propagate and potentially execute further actions, effectively creating a self-replicating worm. This highlights a significant new vulnerability in AI-powered document processing, demonstrating how prompt injection can escalate to full self-replication. 💡 Why read it: It reveals a critical new security vulnerability in AI-powered document tools like Copilot, demonstrating how prompt injection can evolve into self-replicating worms. 🏷️ AI, Prompt Injection, Worm, Security

- Why do OpenAI’s GPT-2 weights beat mine?
Why do OpenAI’s GPT-2 weights beat mine? — gilesthomas.com · 22h ago · 🤖 AI / ML
The author’s custom-trained LLM models performed worse at instruction-following compared to the original OpenAI GPT-2 small weights. The author used an evaluation based on instruction fine-tuning code from “Build a Large Language Model (from Scratch)” and trained their model on a specific dataset. Despite following established methods, their models did not match the instruction-following capabilities of OpenAI’s pre-trained GPT-2. This article explores the discrepancy in performance, suggesting potential underlying factors beyond basic training methodology that contribute to the superior instruction-following of OpenAI’s models. 💡 Why read it: It investigates a common challenge in LLM development: understanding why custom-trained models may underperform compared to established pre-trained weights, even when following similar architectures. 🏷️ LLM training, GPT-2, Instruction following, Model evaluation —

1. Pluralistic: The stupidest imaginable excuses for surveillance pricing (30 Jul 2026)
Pluralistic: The stupidest imaginable excuses for surveillance pricing (30 Jul 2026) — pluralistic.net · 1h ago · ⭐ 26/30
The article critiques the “stupidest imaginable excuses for surveillance pricing,” linking it to historical corporate practices and broader issues of digital rights. It touches upon themes like “enshittification” and the persistent attempts by corporations, exemplified by San Francisco’s Chamber of Commerce since 1850, to normalize exploitative practices. The author also mentions specific examples of digital vulnerabilities and failures, such as Diebold voting machines and RFID car theft, to underscore the pervasive nature of these issues. The piece argues that justifications for surveillance pricing are fundamentally flawed and part of a larger pattern of corporate overreach and user exploitation in the digital age. 🏷️ Surveillance, Privacy, Digital Rights, Ethics —
2. Apple Says iOS 27 ‘Restricted Mode’ Isn’t for Users Who Miss Payments in New Apple Upgrade Program
Apple Says iOS 27 ‘Restricted Mode’ Isn’t for Users Who Miss Payments in New Apple Upgrade Program — daringfireball.net · 17h ago · ⭐ 24/30 Speculation arose that Apple’s new iOS 27 “Restricted Mode” was designed to limit functionality on leased devices for users who missed payments in the new Apple Upgrade Program. Code in the iOS 27 developer beta revealed a “Restricted Mode” that limits devices to a few core apps (e.g., Accessibility Reader, App Store, Phone, Settings, Wallet, Passwords) and limited access to others like Messages. Apple, however, clarified that this feature is not intended for payment defaults in their new leasing program. Despite initial user speculation, Apple denies that iOS 27’s “Restricted Mode” is linked to payment defaults, suggesting it serves another, as yet unstated, purpose. 🏷️ Apple, iOS, Restricted Mode, Payments —

8. Quoting D. Richard Hipp
Quoting D. Richard Hipp — simonwillison.net · 16h ago · ⭐ 21/30 The article quotes D. Richard Hipp, highlighting the transformative impact of SQL on data querying and software development. Hipp explains that before SQL, specialized COBOL programmers were required to write extensive code for querying large datasets. SQL emerged as a declarative language, enabling users to specify queries simply, which then generated the complex underlying code previously written manually. This shift significantly reduced the need for expensive, specialized programming for data access. SQL democratized data querying by abstracting away low-level implementation details, making complex data operations accessible through simple specifications. 🏷️ SQL, COBOL, Database, Programming History —

12. Why compute might get 10x+ more expensive in coming years
Why compute might get 10x+ more expensive in coming years — dwarkesh.com · 23h ago · ⭐ 26/30 The cost of compute, particularly for advanced AI models, is projected to increase significantly, potentially by over 10x in the coming years. This projection is based on a comparison: if an H100 equivalent could run a human-level software engineer, its annual rental rate should exceed $250,000, which is 15 times today’s spot price. This implies that as AI capabilities advance towards human-level performance, the economic value and thus the cost of the underlying compute infrastructure will skyrocket. The increasing demand for powerful compute to run advanced AI, especially human-level AI, will drive a dramatic surge in compute costs, making it a critical economic factor for future technological development. 🏷️ Compute cost, AI economics, H100, Infrastructure —
