Today’s Tech News: Massive Credential Breach, Meta’s Rust-Powered Type Checker, and the End of an Era

Troy Hunt has processed the largest data breach corpus in Have I Been Pwned's history—nearly 2 billion unique email addresses and 1.3 billion passwords, with 625 million passwords never seen before. This isn't a single breach but rather credential stuffing data that criminals use to attempt logins across the internet. The scale is staggering: 32 million different email domains affected, requiring two weeks on maxed-out Azure infrastructure just to process. If you're reusing passwords anywhere, this is your wake-up call to get a password manager.

Meta just open-sourced Pyrefly, a Python type checker rewritten in Rust that's up to 40x faster than mypy on large codebases. This is what's replacing their OCaml-based Pyre for Instagram's massive Python infrastructure. By leveraging Rust's memory safety and parallelism, Pyrefly can analyze multiple files simultaneously without Python's Global Interpreter Lock—and it's fully compatible with existing type annotations. This represents a paradigm shift for Python at scale, making the language viable for even larger enterprise applications.

After more than 200 years of weather predictions and folksy wisdom, the Farmers' Almanac announced it's closing. The 2026 edition will be their last. While scientific studies have shown their long-range forecasts perform no better than random chance, the Almanac endured as a cultural institution for its planting calendars, fishing tables, and comforting rituals.

We also cover AMD's confirmation of a critical vulnerability in all Zen 5 processors affecting the RDSEED cryptographic random number generator, and Nvidia's B300 Blackwell platform delivering 144 petaflops of FP4 performance with 11x faster LLM inference than the previous generation—making massive AI models practically deployable at scale.
