When Zig Outshines Rust – Memory Efficient Enum Arrays
Summary: In Rust, enums with varying-sized variants can cause significant memory fragmentation. Reducing this fragmentation is challenging in Rust, but Zig allows for more efficient and concise data structure transformations. Efficient enum arrays are particularly useful in compilers, where large abstract syntax trees (ASTs) can impact performance. Zig's staged compilation enables generic container types that perform struct-of-arrays (SoA) transformations for any type, while Rust is limited to proc-macros. Zig also allows for composable memory efficiency and fine-grained control over data structure selection, making it a powerful tool for high-performance systems software.

38TB of data accidentally exposed by Microsoft AI researchers
Summary: Microsoft AI researchers accidentally exposed 38TB of data, including private keys, passwords, and over 30,000 internal Microsoft Teams messages, due to a misconfigured SAS token. The data exposure occurred while publishing open-source training data on GitHub. The incident highlights the risks organizations face when handling massive amounts of data for AI development and the need for additional security checks and safeguards.
