Distributed computing shares computational tasks among multiple machines, making it possible to process large volumes of data and perform complex calculations by dividing the workload across networks. This approach has evolved from early local area networks to the internet and cloud computing, enabling efficient and secure data handling.
Archaeologists have discovered an ancient human settlement in Tajikistan that dates back approximately 150,000 years.
Archaeologists from the Hebrew University of Jerusalem and the National Academy of Sciences of Tajikistan have discovered a multi-layered archaeological site in the Zeravshan Valley of Tajikistan. The site, named Soii Havzak, contains artifacts dating back as far as 150,000 years, making it a significant find for understanding early human settlements and migrations in Central Asia.
The discovery suggests that the Zeravshan Valley, known historically as a Silk Road route, was an important migration corridor for human species like Homo sapiens, Neanderthals, and Denisovans.

This paper describes the background and history of Multics Emacs, including the previous developments and the climate in which it was created. It also details the design and implementation experience, and important algorithms such as the redisplay algorithm.
The 'Books' page of FelsenSigns presents a book titled 'Me and My Big Ideas – Counterculture, Social Media, and the Future'. The book chronicles the author's journey through the evolution of social media from the 1960s to the 1980s, exploring its origins, politics, and the need for better information exchange. The author hopes to educate readers on how social media was structured for corporate benefit and how it can be reimagined for societal good.
Lee Felsenstein, a key figure in the evolution of personal computers, explores the rise of social media, AI’s shortcomings, and the golden age of engineering in his new book.

A study published by a multidisciplinary team of researchers proposes that the wheel originated in Neolithic mines of the Carpathian Mountains around 3900 B.C. The study, based on computational mechanical analysis, outlines a three-phase technological evolution of the wheel from free rollers to fixed-axle wheel design.
A new study suggests that the wheel may have been invented by copper miners in the Carpathian Mountains around 3900 B.C., using techniques from structural mechanics to trace the evolution of the wheel and axle.
Online archives are vanishing, taking our history with them.
The article discusses the looming threat of a "Digital Dark Age" as online archives, including Google's URL shortener service, are disappearing. This phenomenon is exacerbated by social networks shutting down, digital journalism sites closing, and companies removing their online products, leading to a significant portion of the web becoming inaccessible. The degradation of links and the shift towards digital storage without proper preservation mechanisms are causing concern. Efforts such as the Wayback Machine are vital for preserving digital content, but they face challenges like paywalls and AI blocking. The article highlights the importance of digital archives in maintaining our collective history and memory, and warns against the risks of self-inflicted cultural amnesia.
