What began as a personal automata theory project evolved into one-more-re-nightmare, a high-performance regex engine hitting 18 GC/s. By leveraging derivatives, Mealy machines for submatching, and SIMD-optimized substring search, it challenges assumptions about regex implementation limits while maintaining a tiny 1,848-line Common Lisp codebase.

Science has retracted a highly contentious 2010 paper claiming a bacterium could replace phosphorus with arsenic in its DNA, a finding that once challenged fundamental biochemistry. The retraction, citing insufficient evidence for its core claims despite no misconduct, marks a shift in the journal's policy and underscores the scientific community's rigorous self-correction process. The decision reignites debate about the paper's legacy and the intense scrutiny faced by its authors.

Project maintainers face endless battles against accidental commits of irrelevant files like .DS_Store and IDE configs. Discover how flipping the traditional .gitignore model to a whitelist strategy can automate cleanup and preserve repository sanity.

IBM's new Power11 processors promise up to 55% faster cores than their 2017-era Power9 predecessors and claim twice the performance per watt of comparable x86 systems. Key innovations include 'resource groups' for optimized utilization, an energy-saver mode, and unique resiliency features like dedicated hot-spare cores for 99.9999% uptime. The chips also integrate on-die AI accelerators, positioning Power11 as a contender in power-conscious data centers.

This comprehensive guide demystifies transformer models from first principles, exploring how attention mechanisms and matrix operations enable breakthroughs in natural language processing. Discover the mathematical foundations and architectural innovations that make transformers indispensable in today's AI landscape.

A new library bridges the Lisp dialect divide by implementing Clojure's collection, sequence, and lazy-seq APIs in Common Lisp. CLJ-COLL enables immutable data structures and functional patterns while maintaining interoperability with native CL types, offering polyglot Lisp developers shared idioms and smoother transitions between ecosystems.
