20 Pandas One-Liners That Can Save You Hours of Work
A curated set of 20 concise Pandas one-liners that leverage advanced features—like Arrow-backed dtypes, vectorized eval, and efficient group-by transforms—to optimize common data preprocessing, filtering, and aggregation tasks. These snippets are designed to streamline data analysis workflows on large datasets by reducing memory usage, speeding up computations, and minimizing boilerplate...
Traffic meter per ASN without logs
The author introduces asncounter, a Python tool that analyzes logs or network traffic to count and group incoming IPs by their Autonomous System Number (ASN), helping identify which organizations are generating the most traffic. It’s designed for quick deployment and practical insight—especially when logs are anonymized or attackers use distributed IPs—making it easier to spot patterns, ...

How local variables work in Python bytecode
The post explains how local variables are managed in Python bytecode: they’re stored in reserved slots at the bottom of each function’s stack frame, with the stack holding references to objects on the heap. By walking through a custom Python interpreter in Rust, the author illustrates how compiled bytecode uses indices (not names) to access these slots, demystifying the stack-based stora...

Surprisingly Fast AI-Generated Kernels We Didn’t Mean to Publish (Yet)
Stanford researchers show that AI-generated CUDA kernels—created without relying on standard libraries—can now match or even outperform expert-optimized PyTorch kernels on specific tasks, thanks to parallel search and synthetic data generation. Their approach demonstrates that combining strong reasoning with broad exploratory search yields rapid performance gains, highlighting a promisin...

Should You Replace Every For Loop With Map and Filter?
Think map() and filter() are always better than for loops? Not so fast. This video walks you through four situations where functional code actually makes things worse—and explain why the classic for loop still deserves a place in your toolbox.
Create your customized running plan: A step-by-step guide using Python, Elasticsearch, and Agno
The article provides a step-by-step guide to building a personalized, AI-powered running plan using Python, Elasticsearch, and Agno, leveraging your workout history to generate a four-week training schedule. It walks through extracting fitness data, storing it in Elasticsearch, using agentic AI to create a tailored plan, and exporting the results to Notion for easy tracking and progress ...
Python Tutorial: Type Hinting vs Type Checking vs Data Validation - What’s the Difference?
In this video, we'll be learning about the differences between type hinting, type checking, and data validation in Python. These are three concepts that many developers get confused about, so we'll cover what each one does, when to use them, and how they work together. We'll also look at practical examples using tools like mypy for type checking and Pydantic for data validation. By the e...
No GPU left behind: Unlocking Efficiency with Co-located vLLM in TRL
Hugging Face’s new co-location feature lets vLLM inference and model training share the same GPUs and process group, eliminating idle GPU time and costly hardware overhead that plagued the old server-based setup. This integrated approach delivers up to 1.73X faster throughput for large language models, maintains model quality, and simplifies scaling—though it requires careful GPU memory ...
