Waterfox has launched a new website and transitioned to waterfox.com. Unlike Mozilla, which is shifting its focus to AI-driven browsing, Waterfox emphasizes that a browser's role is to serve users rather than think for them. Mozilla's CEO aims to establish the company as a trusted software provider with AI at its core, but the creator of Waterfox argues this approach is fundamentally flawed. He expresses concern over AI's opaque nature, particularly large language models (LLMs), which lack transparency and auditability

Texas Attorney General Ken Paxton is suing five major TV manufacturers—Sony, Samsung, LG, Hisense, and TCL—accusing them of being part of a "mass surveillance system" by secretly recording consumers' viewing habits in their homes. The lawsuits, filed on Tuesday, claim these companies utilize Automatic Content Recognition (ACR) technology to collect personal data for targeted advertising. ACR supposedly identifies content being watched, including that from streaming services and connected devices, and may even capture security camera streams

Terence Tao's blog post discusses the recent resolution of Problem 1026 from the Erdős problem website, achieved through a blend of existing literature, online collaboration, and AI tools. The original problem, posed by Erdős in 1975, revolves around the properties of sequences of distinct real numbers and their subsequences. It involves finding optimal bounds for certain quantities related to sequence decomposition and monotonicity. Though the problem was noted to be somewhat ambiguous when it was added to the website in September

ReScript 12 introduces a new build system called Rewatch, which replaces the previous system, bsb. This new build system offers intelligent dependency tracking, faster incremental builds, and enhanced support for monorepo workflows. While bsb was effective for single-package projects, it struggled with limitations in monorepo setups, particularly in watch mode, where it only tracked changes within a single package, failing to trigger rebuilds for dependent packages. Additionally, bsb built packages sequentially rather than in parallel
