    AI models from OpenAI and Google helped researchers find PHP2Shell, two critical PHP flaws that let attackers take over servers with no login. PHP runs about 70% of websites, so WordPress, Drupal and Magento sites on unpatched PHP are all exposed. The NSA says patch to 8.5.12, 8.4.27, 8.3.36 or 8.2.35 now, or take systems offline.

  • Demystifying Python Asyncio: When to Use Concurrency vs. Multiprocessing in Production.

    This story was originally published on HackerNoon at: https://hackernoon.com/demystifying-python-asyncio-when-to-use-concurrency-vs-multiprocessing-in-production.


    Learn when to use Python asyncio, threading, or multiprocessing to improve API performance, handle I/O efficiently, and scale CPU-intensive workloads.

    Choosing between asyncio and multiprocessing starts with identifying your bottleneck. Asyncio improves throughput for I/O-bound workloads by letting tasks share an event loop while waiting for network or database responses. Multiprocessing runs CPU-intensive work across separate processes, bypassing the traditional CPython GIL constraint. This guide explains when to use each approach, how threads fit into the picture, and which production anti-patterns can undermine performance.
