The article argues that as AI automates data queries, pipelines, and models, the real value shifts to “measurement engineers” who decide if we’re measuring the right things and interpret ambiguous results. It breaks down why judgment—construct validity, reliable metrics, and decision theory—is a teachable skill that organizations must build into hiring, training, and structure.

The article discusses the shifting landscape for data scientists and machine learning engineers in the age of large language models (LLMs). It emphasizes the importance of data science fundamentals in evaluating AI systems, addressing common pitfalls in metrics, experimental design, and data quality. The author argues that the core work of data scientists remains vital, even as their roles evolve.

The article discusses how the rise of AI tools, particularly LLMs, has affected software engineering and data work. While some engineers are concerned about the declining quality of code, data professionals find value in these tools for generating quick, low-maintenance solutions. It emphasizes the need for careful evaluation of the new data generated by these systems.

chDB transforms ClickHouse into a user-friendly Python library for seamless DataFrame operations, eliminating serialization overhead and enabling fast SQL queries directly on Pandas DataFrames. The latest version achieves significant performance improvements, making it 87 times faster than its predecessor by implementing zero-copy data handling and optimized processing.

Livedocs is a collaborative platform that merges the functionality of notebooks with app-building simplicity, ideal for various data tasks such as exploration, analysis, and visualization. It supports powerful AI tools, enabling users to perform advanced analytics, create interactive dashboards, and share insights effortlessly.

The removal of Python's Global Interpreter Lock (GIL) marks a significant shift in the language's ability to handle multithreading and concurrency. With the introduction of PEP 703, developers can now compile Python with or without the GIL, enabling true parallelism and reshaping how systems are designed, particularly in data science and AI. This change presents both opportunities and challenges, requiring developers to adapt to new concurrency patterns.
