The content discusses a recurring issue faced by engineering teams regarding the notion of rewriting software. Despite varying technologies and companies, many teams reach a critical juncture where they contemplate rewriting essential software systems that still operate their businesses. This conversation often arises informally, leading to a shared sentiment that the rewrite is a distant possibility rather than an actionable plan. As the idea of a rewrite lingers, it affects team dynamics and responsibility. Engineers begin to disengage from the current system, seeing it as temporary, which

On February 3, 2026, Apple announced the release of Xcode 26.3, which introduces "agentic coding." This feature allows developers to utilize coding agents like Anthropic’s Claude Agent and OpenAI’s Codex directly within Xcode, enabling greater autonomy in app development. The new tools assist developers in automating complex tasks, making decisions based on project architecture, and streamlining workflows throughout the development lifecycle. This update builds on prior enhancements in Xcode 26, which

A new API has been introduced by Deno to securely run untrusted code in lightweight Linux microVMs, addressing the rise in LLM-generated code that calls external APIs without human review. The key challenges include safeguarding API keys and controlling network access. Deno Sandbox addresses these issues by allowing immediate deployment without rebuilding, isolating untrusted code execution, and ensuring that sensitive information doesn’t enter the environment. Secrets are only revealed during approved outbound requests, and attempts to exfiltrate credentials are thwarted

The content discusses the evolving role of LLM (Large Language Model) agents in software development, suggesting that they may significantly enhance developer productivity, enabling humans to build software at a scale 10 times greater than before. The hypothesis being considered is whether LLMs can truly improve software development efficiency. There are common objections to this idea, particularly regarding quality and understandability in programming frameworks. While the author acknowledges the importance of quality as an essential goal, they view understandability as a subjective aspiration.

The Environmental Protection Agency (EPA) effectively reduced lead levels in the environment in the 1970s by regulating lead-based products like lead paint and leaded gasoline, resulting in a 100-fold decrease in lead concentrations in human hair over nearly a century, according to researchers from the University of Utah. Their findings, published in the Proceedings of the National Academy of Sciences, underscore the importance of these regulations, especially in light of recent attempts by the Trump administration to deregulate parts of the EPA’s mission

The article discusses the challenges of using AI in software development, particularly regarding its effectiveness in production. It highlights two critical points: coding assistants require clearly defined requirements to be effective, and edge cases often arise during implementation that can lead to gaps in understanding. Unlike human developers, who can escalate issues regarding unclear requirements, AI coding assistants may obscure these gaps within complex code, resulting in breaking changes and unmaintainable code. This leads to more time spent on code reviews and fixing vulnerabilities. While some engineers

The research conducted during the first Anthropic Fellows Program in Summer 2025 investigates how AI systems fail, focusing on whether these failures are due to systematic goal misalignment or incoherent behavior. The study finds that as tasks become more complex and reasoning lengthens, failures of AI models are increasingly characterized by incoherence rather than systematic errors. This challenges the traditional alignment concern, highlighting the possibility that advanced AI might fail in unpredictable ways, similar to the chaotic behavior observed in humans—termed the "hot
