The narrative discusses the complexities of interpreting performance metrics in production environments. Despite seemingly healthy metrics like 60% CPU utilization and 40% free memory, issues can arise, leading to user complaints and high latency, highlighting the need for deeper analysis. Basic metrics often lack context, and the guide aims to improve understanding of Linux performance metrics and troubleshooting. It emphasizes the importance of assessing load average in relation to the run queue depth rather than CPU core count, as this can reveal performance issues. A situation where

The content discusses rendering techniques for a voxel game involving cubes in a grid. Initially, every cube is rendered with twelve triangles, but many faces are naturally hidden by adjacent cubes, allowing for some triangles to be discarded. To optimize rendering, visible triangles within a 16×16×16 section are combined into a buffer for more efficient rendering. Basic occlusion culling checks if each section intersects with the camera's view to avoid rendering invisible sections. Despite this, hidden sections can still be rendered,

pgEdge has announced the release of pgEdge Enterprise Postgres, highlighting the rewarding yet challenging experience of creating extensions for Postgres. Building upon a previous article about a simple extension that blocked DDL, this new discussion focuses on developing a more comprehensive extension that allows users to track memory usage in Postgres. Traditional tools provide vague memory metrics, but by utilizing the Linux /proc filesystem, particularly the smaps file, developers can create a table that details memory usage per Postgres backend process. This would

In 1988, Cornell graduate student Robert Tappan Morris released the Morris worm, one of the first significant pieces of malware, onto the Internet, which had not yet fully developed into the World Wide Web. Intended to measure the size of the Internet, the worm quickly infected about 10% of all Internet-connected systems, causing extensive damage. Although not maliciously created, it exploited vulnerabilities in BSD UNIX systems and spread autonomously without needing a host program. The resulting issues included significant slowdowns

The document discusses **SlopGuard**, a tool designed for detecting AI-hallucinated package dependencies, typosquatting, and supply chain attacks through automated trust scoring. Traditional software composition analysis (SCA) tools often fail to validate package existence during dependency resolution, which leaves developers vulnerable to attacks like slopsquatting. SlopGuard features a three-stage lazy-loading trust scoring system that effectively learns from package ecosystem patterns, leading to a significant reduction in API calls (70% fewer) compared

The content discusses the economic implications of productivity bursts in specific industries, particularly relating to the impact of AI. It highlights how such productivity increases lead to lower costs and higher consumption in affected sectors while simultaneously affecting wages across different industries as more jobs and opportunities emerge. This phenomenon is described through Jevons Paradox, where increased productivity leads to higher consumption, and the Baumol Effect, where services that do not experience similar productivity gains become more expensive. As the AI supercycle unfolds, it is anticipated that
