#TIL Nature Human Behaviour: 早八影响睡眠并降低绩点
https://www.nature.com/articles/s41562-023-01531-x
Attending classes and sleeping well are important for students’ academic success. Here, we tested whether early morning classes are associated with lower attendance, shorter sleep and poorer academic achievement by analysing university students’ digital traces. Wi-Fi connection logs in 23,391 students revealed that lecture attendance was about ten percentage points lower for classes at 08:00 compared with later start times. Diurnal patterns of Learning Management System logins in 39,458 students and actigraphy data in 181 students demonstrated that nocturnal sleep was an hour shorter for early classes because students woke up earlier than usual. Analyses of grades in 33,818 students showed that the number of days per week they had morning classes was negatively correlated with grade point average. These findings suggest concerning associations between early morning classes and learning outcomes.
上课和良好的睡眠对学生的学业成功非常重要。我们通过分析大学生的数字痕迹测试了早晨早课是否与低出勤率、较短的睡眠时间和较差的学业成就相关联。对23,391名学生的Wi-Fi连接日志分析结果显示,8:00的课程出勤率比较晚开始的课程低约十个百分点。对39,458名学生的学习管理系统登录日志和181名学生的动作记录数据的日节律模式分析显示,早课导致夜间睡眠时间短了一小时,因为学生比平时早起。对33,818名学生成绩的分析显示,每周上早课的天数与平均成绩点数(GPA)呈负相关。这些研究结果表明,早晨早课与学习成果之间存在令人担忧的关联。

Early morning university classes are associated with impaired sleep and academic performance
Nature Human Behaviour - Yeo et al. use digital data on student behaviour (Wi-Fi connections and Learning Management System logins) to examine associations between sleep and academic outcomes.

When ChatGPT summarises, it actually does nothing of the kind.
One of the use cases I thought was reasonable to expect from ChatGPT and Friends (LLMs) was summarising. It turns out I was wrong. What ChatGPT isn’t summarising at all, it only looks like it…

在禁言 11 年之后玩家重续旧话题

Something Awful(SA)是一个神奇的论坛,你需要支付 10 美元才能成为注册用户。它是很多互联网文化的发源地,催生了知名或臭名昭著的 4chan 匿名讨论版,4chan 最初是由 SA 动漫子论坛的异见用户创建的。SA 给了论坛版主相当大的封禁裁量权,如果发帖者被认为违反了礼仪或其它情况,他们会被禁言一段时间,SA 建立了专门的网页展示相关的封禁信息,包括封禁长度和原因。一位叫 Etherwind 的用户在桌游子论坛发帖,开玩笑的说 World of Darkness TTRPG 的一位作者应该去死。他随后被禁言了 10 万个小时——对绝大部分的人而言这意味着永久性封禁。Etherwind 的禁言始于 2013 年 2 月 14 日 10:24 pm BST,终于 2024 年 7 月 13 日。在禁言 100,018 小时后的 7 月 14 日 9:04 BST,Etherwind 再次亮相论坛,继续 11.4 年前的讨论话题。有用户建议应该再禁言他 11 年。他分享了一篇 Google 文档,谈论了他过去几年的心路,承认出于喜剧效果而给自己设定了禁言结束的日期提醒。
