IBM's Executive Terminal: A Forgotten Chapter in Computing History

A recently discovered 1968 videotape reveals IBM's previously unknown "Executive Terminal" system. Unlike Engelbart's "Mother of All Demos," which emphasized collaboration, this system created an information "war room" for top IBM executives. Executives used modified television sets to query information specialists, who then compiled information from various terminals and resources, presenting it visually to the executives. This showcases an alternative application of early computing technology within a hierarchical organization, contrasting sharply with the collaborative approach of the "Mother of All Demos." Together, they offer a fascinating glimpse into the early development of computing.

New Study Pinpoints Neanderthal Interbreeding with Modern Humans

A new analysis of ancient DNA from modern humans in Europe and Asia has precisely determined the timeframe of Neanderthal interbreeding with Homo sapiens. The interbreeding began approximately 50,500 years ago and lasted for about 7,000 years, until Neanderthals began to disappear. This research, using 58 ancient genomes and present-day human genomes, revealed an average interbreeding date of around 47,000 years ago, consistent with archeological evidence. The study also found that East Asians possess about 20% more Neanderthal genes than Europeans and West Asians, potentially due to the presence of mixed genes when modern humans migrated eastward around 47,000 years ago. The findings offer a more complete picture of past human migrations and gene flow, and shed light on the impact of Neanderthal genes on modern human health.

Study Reveals Misperception of Opposite-Sex Facial Preferences

Study Reveals Misperception of Opposite-Sex Facial Preferences

A PLOS ONE study reveals that both men and women overestimate the opposite sex's preference for sexually dimorphic facial features (masculine or feminine traits). Using interactive 3D head models, participants chose their own ideal face shape and the face shape they believed the opposite sex would find most attractive. Women overestimated men's preference for feminine faces, while men overestimated women's preference for masculine faces. This misperception correlated with the discrepancy between participants' own and ideal facial dimorphism (an index of appearance dissatisfaction). The study suggests that misperceiving opposite-sex preferences contributes to appearance dissatisfaction.

The World of Tomorrow: Why Did Progress Lose Its Glamour?

This article explores the allure and subsequent fading of the 'World of Tomorrow' vision prevalent in the mid-20th century. It traces the evolution of societal yearnings for a better future, from the pursuit of efficiency, order, and speed to desires for exploration, adventure, and achievement, and finally, the longing for security, comfort, and ease. However, as technological advancements became reality, their flaws emerged, such as the blandness of industrialized food and the destructive nature of urban renewal projects. The author argues that disillusionment with progress stems from a misunderstanding of progress itself – the pursuit of 'one best way' rather than acknowledging diversity and individual preferences. To regain progress's charm, understanding contemporary aspirations and providing possibilities for various lifestyles, rather than a single future blueprint, is crucial.

The Humble For Loop in Rust: Performance and Readability

2024-12-12

This article explores the trade-offs between the humble `for` loop and functional programming approaches like `map` and `fold` in Rust, considering both performance and readability. Through benchmarks comparing different methods on vector and nested vector operations, the author finds that `map` often outperforms `for` loops in simple transformations, offering better declarative style. However, for more complex scenarios such as flattening nested vectors or handling errors, `for` loops demonstrate a significant performance advantage and maintain greater code clarity. The author advocates for a pragmatic approach, choosing the best tool for the job rather than blindly favoring functional programming.
