Today’s Highlights

The tech world is currently grappling with significant challenges in AI privacy and data security, highlighted by a class-action lawsuit against Perplexity AI for alleged deceptive “Incognito Mode” practices and a reported email leak from BrowserStack. In response, developers are actively building and refining essential tools, such as new versions of scan-for-secrets to prevent sensitive data exposure and major refactors of AI libraries like Simon Willison’s llm for improved functionality. This dual emphasis on robust security tooling and advanced AI development reflects the industry’s commitment to both innovation and safeguarding user data. —

  1. Class Action Lawsuit Says Perplexity’s ‘Incognito Mode’ Is a ‘Sham’ Class Action Lawsuit Says Perplexity’s ‘Incognito Mode’ Is a ‘Sham’ — daringfireball.net · 13h ago · 🔒 Security

    A class-action lawsuit alleges that Perplexity AI’s “Incognito Mode” is deceptive, claiming it fails to protect user privacy. The lawsuit, based on developer tool findings, states that initial prompts and follow-up questions are always shared. For non-subscribed users, initial prompts are allegedly shared via a URL accessible by third parties like Meta and Google. Disturbingly, the complaint also claims chats are shared with other entities, undermining the promise of privacy. 💡 Why read it: This article is worth reading for anyone concerned about AI service privacy, as it highlights potential misrepresentation of ‘incognito’ features and the sharing of user data with third parties. 🏷️ Perplexity AI, privacy, incognito mode, lawsuit

    Simon Willison is undertaking a major refactor of his llm Python library and CLI tool, as detailed in research-llm-apis 2026-04-04. The llm library provides an abstraction layer for hundreds of LLMs from various vendors through its plugin system. This change addresses the challenge of new features introduced by vendors over the past year, which the current abstraction layer struggles to fully support. The refactor aims to create a more adaptable and comprehensive abstraction for evolving LLM API capabilities. 💡 Why read it: It offers insight into the complexities of maintaining a universal abstraction layer for rapidly evolving LLM APIs and the design considerations for future-proofing such tools. 🏷️ LLM, Python library, API design, release

8. Kalman and Bayes average grades

Kalman and Bayes average grades — johndcook.com · 23h ago · ⭐ 22/30 This post simplifies the problem of updating an average grade, presenting it as a special case of both Bayesian statistics and Kalman filtering. It demonstrates how to calculate a new average m_new given an existing average m_old from n tests and a new test score x_new. The article shows that both advanced statistical methods yield the intuitive formula: m_new = (n * m_old + x_new) / (n + 1). This illustrates the fundamental connection between these seemingly complex statistical techniques and a common averaging problem. 🏷️ Kalman filter, Bayesian statistics, Estimation, Statistics —
