• Where Does SIMD Help Post-Quantum Cryptography? A Micro-Architectural Study of ML-KEM on x86 AVX2 4 April 2026

  We systematically decompose the sources of SIMD speedup for ML-KEM (Kyber) on Intel x86-64 AVX2. By benchmarking four compilation variants, we demonstrate that GCC’s auto-vectorizer provides negligible benefit, and that hand-written AVX2 assembly delivers a $35\times$–$56\times$ performance increase for core arithmetic operations. This drives an end-to-end KEM speedup of $5.4\times$–$7.1\times$.

• The Philosophical Legacy of Dostoevsky's Implicit Rejection of Logic and Science in Part I of Notes from Underground 24 October 2025

  Notes from Underground is widely admired as a cornerstone of literature, culture, and philosophy. This paper develops the argument that the primary philosophical undercurrent is a rejection of logic and science as end-alls in modern life, traced through comparison with the more explicitly articulated works of Dostoevsky’s contemporaries and successors: Nietzsche, Heidegger, Shestov, Ellul, Sartre, Camus, Husserl, and Arendt.
