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

Optimise for continuous change, not modernisation or legacy

Published: 2025-11-08 | Origin: /r/programming

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
