    150 by chmaynard 10h ago | | |

    Article: 25 min

    The article discusses the ongoing issue of web scraping by AI scraper bots and residential proxy networks, which overwhelm websites with traffic in search of training data for large language models. The problem has persisted despite efforts from website operators to defend against such attacks, including implementing measures like proof-of-work systems and commercial services. The article also mentions the recent takedown of a bot network called NetNut by Google, but notes that this action is likely temporary as similar networks will re-emerge.

    The Internet as a whole is caught in the crossfire of this arms race between website operators and scraper networks, potentially leading to a loss of content indexing and fragmentation of the open web.
    • Scraper traffic predominantly comes from residential and mobile networks directed by central command-and-control nodes.
    • There are different types of operators running residential-proxy networks, including criminal ones and those offering 'ethically sourced' IP addresses.
    • Web-site operators have been scrambling to defend their sites while minimizing the effect on actual users.
    • LWN was subjected to a heavy scraper attack recently but managed to bear the traffic well enough that most readers did not notice.

  10. Late Bronze Age Collapse from acoup.blog
    347 by dmonay 18h ago | | |

    Article: 1 hr 2 min

    The article discusses the Late Bronze Age Collapse, an event in which major states across the Eastern Mediterranean and Middle East collapsed around 1200 BC. The collapse is characterized by site destructions visible archaeologically from c. 1220 to c. 1170 BC, with uneven impacts on different regions. The article provides a brief overview of the period's political landscape, focusing on the interconnected states in Mesopotamia, Syria, Anatolia, and Egypt, and their economic complexity, including trade networks for resources like bronze. It then delves into the causes and effects of the collapse, with climate change being identified as one significant factor contributing to crop failures that destabilized these states. The article also discusses theories about migrations and natural calamities but ultimately dismisses them in favor of a more nuanced understanding involving political instability, warfare, and resource strain. The effects of the collapse are unevenly distributed across regions, leading to prolonged fragmentation in Anatolia and the Levant while other areas like Egypt and Mesopotamia experience declines rather than complete collapses. The article concludes with an exploration of how the collapse influenced the development of new political institutions, such as the Greek polis, and cultural advancements like the Phoenician alphabet.
