Python 3.15’s interpreter for Windows x86-64 should hopefully be 15% faster
24 December 2025 Some time ago I posted an apology peice for Python’s tail caling results. I apologized for communicating performance results without noticing a compiler bug had occured. I can proudly say today that I am partially retracting that apology, but only for two platforms—MacOs AArch64 (XCode Clang) and Windows x86-64 (MSVC). In our […]

This is not criticism. It is an observation—one repeatedly confirmed in the field. Phrases like “the Asian market,” “the […]
Quantum Error Correction Goes FOOM
In this post: why I expect the maximum achievable qubit quality to increase drastically in the next few years. In 2014, the John Martinis group at UCSB performed an experiment where they stored a classical bit using their quantum computer. They protected the bit with a 9 qubit quantum repetition code. The protected bit had […]
