Agile methodologies prioritize speed and flexibility in software development but often neglect security, increasing risks to software integrity. To counter this, it is vital to integrate secure coding practices throughout the software development lifecycle (SDLC), ensuring security is a core element rather than an afterthought. Research from Secure Code Warrior shows that 67% of developers acknowledge shipping code with vulnerabilities. By embedding security into each development sprint, organizations can proactively tackle risks and potentially reduce vulnerabilities by up to 53%. This proactive approach aligns with

In 1980, biologist Paul Ehrlich and economist Julian Simon entered a bet regarding the future prices of five materials—chromium, copper, nickel, tin, and tungsten—over the next decade. Ehrlich anticipated that population growth would deplete resources, causing prices to rise. In contrast, Simon believed that human innovation would counteract shortages, leading to declining prices. They agreed on a wager of $1,000, with Ehrlich betting that prices would increase and Simon betting they would

Vector graphics are crucial in design due to their resolution independence and flexibility. Recent advancements in vision-language and diffusion models have led to increased interest in generating vector graphics from text. However, many current methods produce over-parameterized outputs and neglect the layered structure that is essential to vector graphics, limiting their usability. To address these issues, the authors propose NeuralSVG, a neural approach that generates vector graphics in layered SVG format from text prompts. Inspired by Neural Radiance Fields, NeuralSVG encodes scenes into

Fidget is a library designed for handling large-scale mathematical expressions, primarily intended as a backend for implicit surfaces. It can represent, compile, and evaluate complex arithmetic clauses for various applications. Implicit surfaces are mathematical functions that provide a distance value for points in 3D space, allowing the determination of whether these points lie inside or outside a model (e.g., a sphere). The library specializes in closed-form implicit surfaces that use basic arithmetic operations, contrasting with flexible representations like GLSL, which can
