Meta Whistleblower Accuses Zuckerberg of Prioritizing Power Over US National Security

Former Meta employee Sarah Wynn-Williams testified before a Senate Judiciary subcommittee, accusing Mark Zuckerberg of prioritizing power over US national security. She alleges that Zuckerberg, in an effort to curry favor with the Chinese government, compromised American interests by assisting in censorship and providing user data to the CCP. Wynn-Williams' testimony also details Meta's attempts to silence her and suppress her book, "Careless People," which details alleged dealings with the Chinese government and accusations of sexual harassment. Meta denies the accusations, calling them "divorced from reality and riddled with false claims." Lawmakers are demanding Zuckerberg testify before the committee.

AI Writes Code, AI Reviews It? Is That Silly?

Daksh, co-founder of Greptile, discovered that an AI code generation tool, Devin, was submitting more pull requests than any human engineer. This raises the intriguing question: should AI-generated code be reviewed by AI itself? While LLMs are stateless, each call is independent, this doesn't mean AI perfectly reviews its own code. AI-generated code, while boosting efficiency, may introduce bugs humans struggle to find. Research shows AI is more effective than humans at finding certain types of bugs, although its accuracy still needs improvement. Ultimately, the article argues that while not perfect, AI code review is more effective than humans at finding specific bug types introduced by AI itself.

Why Frameworks Are Evil: A Case for Libraries

This article delves into functional library design principles, focusing on composability and avoiding callbacks. The author argues that frameworks are difficult to compose, explore, and test, and restrict code structure. In contrast, libraries offer greater developer control, encourage interactive exploration, and support multiple layers of abstraction. Using a game engine example, the article demonstrates how asynchronous workflows and event-based programming can mitigate the drawbacks of callbacks. Examples like FsLab illustrate the composability of libraries. Ultimately, the author advocates for building composable, easily explorable libraries instead of rigid frameworks.
