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 author experimented with a new method for decompiling Java class files that improves on traditional tools like Vineflower, particularly focusing on decompiling control flow, which enhanced performance for their prototype. Initially, they thought extending this method to handle exceptional control flow, such as try...catch blocks, would be simple, but they encountered many complexities. The intricacies stem from various factors including odd behaviors from the Java compiler (javac), the design of the Java Virtual Machine (JVM), and the

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

The author, a software developer, discusses the significance of terminal emulators like iTerm2, PuTTY, and GNOME Terminal, which interpret text and formatting for display on screens. While commonly referred to as "terminals," these tools are actually "terminal emulators" that mimic older hardware terminals, primarily the xterm, which emulates the DEC VT102 terminal. The VT100 was the most popular model developed by Digital Equipment Corporation (DEC) and set a standard for compatibility in subsequent models

The author reflects on a significant lesson learned from Drew DeVault at Linode a decade ago. Despite being one of the youngest developers, Drew passionately advocated for thoughtful architecture and coding decisions in a culture that often prioritized expediency. His ability to persuasively challenge the status quo led to a transformation within the engineering organization, demonstrating that one doesn't need to wait for seniority to enact meaningful change. Key takeaways include valuing debate, being prepared with facts, being persistent in advocating for change, and

The content critiques advice from Better Specs on using RSpec's shared examples feature to make test code DRY (Don't Repeat Yourself). The author questions whether making test code DRY is beneficial, highlighting the confusion caused by the examples provided by Better Specs. The examples demonstrate both "good" and "bad" testing approaches, but the author finds them technically and pedagogically flawed. They argue against the notion that reducing redundancy in test code is inherently good and suggest the need for a deeper understanding of shared examples

The content provides an overview of how memory management works in Linux on x86-64 systems, explaining the illusion of a continuous block of memory utilized by programs. In reality, this memory is managed using a paged approach. Key points include: 1. **Virtual vs. Physical Memory**: Programs see a virtual view of memory that doesn't match the actual physical layout of RAM, which is made up of scattered frames. 2. **Page Tables**: The system uses a page table to map virtual
