Bio-Inspired Adaptive Shading: Energy-Autonomous & Sustainable

2025-01-21

Researchers at the Universities of Stuttgart and Freiburg have developed a novel energy-autonomous building facade shading system, "Solar Gate," inspired by pine cones. Using bio-based cellulose materials and 4D printing, the system passively adjusts shading based on humidity and temperature changes, requiring no electricity. It closes in summer to minimize solar radiation and opens in winter to maximize sunlight for natural heating, offering a sustainable and efficient solution for climate control in buildings.

Redis UNLINK vs DEL: A Deep Dive into Internal Mechanics

2025-01-21

Both Redis' UNLINK and DEL commands remove keys, but their internal implementations differ. DEL synchronously deletes keys and frees memory, while UNLINK asynchronously queues the deletion for background processing. UNLINK's 'non-blocking' nature isn't absolute; it calculates the cost of deleting an object: if the cost is less than 64, it deletes synchronously; otherwise, asynchronously. The article delves into the Redis source code, explaining the implementation details of UNLINK and DEL, including key slot calculation, two-phase unlinking, and asynchronous deletion, and discusses the role of LAZYFREE_THRESHOLD.

Python 3.14's Concurrency and Parallelism Improvements: The Future of Async?

2025-09-02

Python 3.14, releasing soon, brings significant improvements in concurrency and parallelism with PEP 779 (officially supported free threading) and PEP 734 (multiple interpreters in the stdlib). However, despite async/await existing for a decade, its adoption remains lower than expected. The article analyzes the reasons: async excels at I/O-bound tasks but is limited in areas like file I/O; the GIL restricts true parallelism in multithreading; maintaining both synchronous and asynchronous APIs increases development and maintenance costs. The author suggests that Python 3.14's new features might reduce reliance on async programming, offering more practical concurrency and parallelism solutions through free threading and multiple interpreters.
