Teaching NumPy's ufuncs new tricks The post explains how NumPy’s universal functions (ufuncs) work in C and how their internals were upgraded to support multi-output reductions, enabling the long-requested np.minmax function. It also covers ongoing work on segmented reductions for ragged data and converting existing functions into generalized ufuncs (gufuncs) for subarray processing. https://labs.quansight.org/blog/teaching-numpys-ufuncs-new-tricks

Reading __dict__ once permanently deoptimizes attribute access Since 3.11 attribute access has not been a dict lookup, and reading dict once takes the specialized path away for good https://deadlovelll.github.io/2026-09-05-reading-dict-deoptimizes-attribute-access/

TPU Inference Externalization Full Steam Ahead The article examines Google’s push to make TPUs a first-class platform for external LLM inference, including TorchTPU, vLLM, SGLang, and a rapidly maturing open software stack. Benchmarks TPUv7 Ironwood against NVIDIA B200/B300 and dives into the kernel, memory, networking, and serving optimizations behind its performance-per-dollar gains. https://inferencex.semianalysis.com/blog/tpu-inferencex-full-steam

Building AI Agents in Pure Python - Beginner Course Build a fully functioning AI agent from scratch in pure Python, without frameworks, third-party tools, or vibe coding. The course focuses on the core mechanics behind agents so you understand how they work under the hood, not just how to prompt existing tools. https://www.youtube.com/watch?v=c9AnqCeyxbI

KV, Prefix, Prompt and Semantic Caching in LLMs, clearly explained The post explains the four caching layers in LLM stacks: KV cache, prefix caching, prompt caching, and semantic caching, covering what each stores, their trade-offs, interactions, and the most common issues that prevent reuse. It includes first-principles explanations, code demos (with transformers and vLLM-style logic), production pitfalls, and practical takeaways for reducing recomputa... https://x.com/_avichawla/status/2093265776266637739

Tracing np.add, all the way down The author traces a simple np.add(a, b) call through NumPy’s internals, from Python argument handling and dtype dispatch to iteration strategy and the final SIMD-optimized C loop. Along the way, the post explores ufunc overrides, type promotion, dispatch caching, memory layout, GIL release, and CPU-specific optimizations that determine how NumPy actually performs an addition. https://blog.veitheller.de/numpy.html
