    Auto Polo: A Brief History and Overview

    • Auto polo was invented in the United States by Ralph 'Pappy' Hankinson as a publicity stunt to sell Model T cars.
    • The sport featured rules similar to equestrian polo but used automobiles instead of horses.
    • Auto polo was popular from 1911 until the late 1920s, with matches held at fairs and exhibitions in the US and Europe.
    • Safety concerns were significant due to car collisions and falls during games, leading to high costs for vehicle replacements.

    Discussion (9):

    The comment thread discusses various alternative sports that incorporate modern technology, such as Segway polo, motoball, unicycle hockey, and WhirlyBall. The discussion is neutral with a slight positive sentiment towards the potential for these activities. There's also a mention of the high cost associated with replacing vehicles in motoball, which led to its decline.

    • Segways would be ideal for modern recreation of polo
    Counterarguments:
    • Motoball is played in a 5v5 format. There are four players on motorcycles, and one on their feet as the goalkeeper.

  5. New copy of earliest poem in English, written 1,3k years ago, discovered in Rome from tcd.ie
    59 by giuliomagnifico 1d ago | | |

    Article: 12 min

    Researchers from Trinity College Dublin have discovered a new copy of the earliest known poem in English, Caedmon's Hymn, dating back to between 800 and 830 AD. The manuscript was found in Rome's National Central Library and contains the poem in Old English within its main text, making it the third oldest surviving version of the work.

    • This discovery is significant because it contains Caedmon’s Hymn in Old English within its main body of text, unlike two older copies which have the poem in Latin with the Old English text only added marginally or at the end.
    • The poem was composed by a cowherd from Whitby, North Yorkshire, after a divine visitation and is said to be the oldest known poem in Old English.

    Discussion (26): 9 min

    This comment thread discusses the discovery of an Old English poem, its translation, historical context, and connections between languages. It also touches upon cultural influences on the English language, the complexity of 'Englishness', and the evolution of translations.

    • Old English vocabulary mostly predates Viking invasion.
    Counterarguments:
    • The Bible could easily be translated in many different ways, but the 'King James' version is considered the standard within the Anglican churches in the UK (and seems to be the common root for US church bibles too),

    Discussion (389): 1 hr 23 min

    The discussion revolves around the Linux kernel team's responsibility in communicating with downstream distributions about security patches, the necessity of immediate public disclosure to protect users from potential exploitation, and the role of security researchers in following established industry standards. There is a consensus on the importance of transparency but differing opinions on the optimal timeline for disclosure.

    • The Linux kernel team should have communicated more effectively with downstream distributions about the importance of the patch.
    • Immediate public disclosure is necessary to protect users from potential exploitation, even if it means bypassing traditional coordination processes.
    Counterarguments:
    • Security researchers are under no obligation to engage in coordinated disclosure, especially when they follow established industry standards.
    • Immediate public disclosure can lead to a free-for-all where attackers analyze commit logs and exploit vulnerabilities before patches are widely distributed.
