A study conducted by the Oxford Internet Institute, involving 42 researchers from various prestigious institutions, has revealed that many benchmarks used to evaluate large language models (LLMs) lack scientific rigor. The study, titled "Measuring What Matters: Construct Validity in Large Language Model Benchmarks," reviewed 445 AI benchmarks and found many of them are based on unclear definitions and weak analytical methods, complicating the assessment of AI progress, capabilities, and safety. Lead author Andrew Bean emphasized the importance of sound

During The Big Tech Debate on June 12th, Jacob Clark, Director of Engineering, argued against the motion that “Modernisation is overrated – legacy applications still deliver.” He emphasized that the concept of legacy systems lacks a clear definition, with interpretations varying among different roles in an organization. Clark suggested that legacy systems are typically those that are difficult or costly to change, or where the personnel capable of implementing changes are unwilling. He provided three perspectives on legacy: engineers may see it as code written

In this tutorial, you will learn to create an animated plasma effect using Ruby2D, a classic visual effect from the demoscene that produces flowing, colorful patterns resembling liquid plasma. The effect is achieved by combining multiple sine waves that fluctuate over space and time, resulting in smooth and organic animations. The tutorial starts by setting up a 640x480 window with a black background in Ruby2D. Instead of processing colors for each pixel, it divides the window into an 80x60 grid

The blog post discusses the adaptation of Conway's Game of Life into a playable single-player version. Traditionally a "zero-player game," it evolves automatically based on initial patterns and four simple rules, making it more of a simulation. The author created a new interactive format where players can influence the game by altering the bottom row of an 8x8 grid, known as the activation zone, while the sides of the grid wrap around. In this version, players aim to activate specific goal cells while minimizing
