Prior to WWII the U.S was a distant second in science and engineering. By the time the war was over, U.S. science and engineering had blown past the British, and led the world for 85 years. It happened because two very different people were the science advisors to their nation’s leaders. Each had radically different…

20. What Is Entropy? (jasonfantl.com)

People say many things about entropy: entropy increases with time, entropy is disorder, entropy increases with energy, entropy determines the arrow of time, etc.. But I have no idea what entropy is, and from what I find, neither do most other people. This is the introduction I wish I had when first told about entropy, so hopefully you find it helpful. My goal is that by the end of this long post we will have a rigorous and intuitive understanding of those statements, and in particular, why the universe looks different when moving forward through time versus when traveling backward…

24. Philosophy Major Snatched by ICE During Citizenship Interview (dailynous.com)

Mohsen Mahdawi, a philosophy major at Columbia University who is due to graduate later this semester, was attending a US citizenship application interview in Vermont on Monday when Immigration and Customs Enforcement (ICE) agents wearing hoods and masks took him from the building, put him into an unmarked car, and drove off. His current whereabouts are “unknown”, said his lawyer, according to the BBC. Mahdawi is a green card holder. According to the BBC: His lawyer, Luna Droubi, said: “The Trump administration detained Mohsen Mahdawi in direct retaliation for his advocacy on behalf of Palestinians and because of his identity as a Palestinian. “His detention is an attempt to silence those who speak out against the atrocities in Gaza. It is also unconstitutional.” The attorney applied to a federal court for a temporary restraining order to prevent US immigration authorities moving Mr Mahdawi out of Vermont or expelling him from the US. Judge William Sessions, an Obama appointee, quickly granted that order. The court filing says Mr Mahdawi was born in a refugee camp in the West Bank and moved to the US in 2014. It describes the philosophy major as a committed Buddhist who believes in “non-violence and empathy as a central tenet of his religion”. Mahdawi was interviewed last year by 60 Minutes about the student protests at Columbia regarding Israel’s response to Hamas’s attack on October 7th, 2023. In the interview he says: To be anti-Semitic is unjust. And the fight for the freedom of Palestine and the fight against anti-Semitism go hand in hand, because injustice anywhere is a threat to justice everywhere. A clip of the interview is below. (via Shen-Yi Liao) UPDATE: Via Deborah Achtenberg, I learned about a public Facebook post by David Myers, professor of history, holder of the Sady and Ludwig Kahn Chair in Jewish History, and former director of the Center for Jewish Studies at UCLA: Coming off of two days of Passover, I was horrified to discover that my friend, Columbia student Mohsen Mahdawi, was arrested. I met Mohsen at a meeting in late spring 2024 and have been in touch with him ever since. He is a remarkable and humane person who experienced the worst of Israel’s occupation as a young..

36. Understanding the Origins and the Evolution of Vi and Vim (pikuma.com)

Vi与Vim的起源与演变

Vi和Vim的历史与开源软件的发展紧密相连。文章追溯了UNIX文本编辑器的起源,探讨了塑造其发展的关键人物与事件。

早期编辑器:从Ed到Em

  • Ed:由Ken Thompson创建的行编辑器,最初为电传打字机设计,而非显示终端。其命令晦涩,用户体验不佳。
  • Em:1976年,伦敦玛丽王后大学的讲师George Coulouris对Ed感到不满,基于其源码开发了Em(Ed for Mortals)。Em是首个在UNIX上广泛使用“原始终端输入模式”的程序,专为显示终端优化。

Vi的诞生

  • 1976年,Thompson访问加州大学伯克利分校时,学生Bill Joy在修复一个Pascal编译器时深感Ed的局限。
  • 同年夏,Coulouris访问伯克利,展示了Em。Joy和Chuck Haley受Em启发,在改进的Ed基础上开发了en编辑器,随后扩展为ex
  • 1977年10月,Joy为ex添加了全屏视觉模式,形成了vi。vi本质上是ex的视觉模式。
  • vi的命令设计深受当时使用的ADM-3A终端键盘布局(如Esc键位置)和300波特调制解调器的低速连接影响,强调命令简洁高效。
  • 1978年,vi随首个BSD UNIX版本发布而广泛传播。

Vi克隆的兴起与Vim的崛起

  • 因vi源码基于AT&T的Ed,受许可证限制,催生了众多vi克隆版本。
  • Stevie:1987年发布的首个vi克隆,为Atari ST编写,未使用原始vi代码,成为后续克隆的重要参考。
  • Elvis:因Stevie不稳定而创建,首创语法高亮功能,并被MINIX系统采纳为默认编辑器。
  • Vim:由Bram Moolenaar于1988年为Commodore Amiga开发,最初基于Stevie的源码(避免许可证问题),名称意为“Vi IMitation”。1991年首个公开版本发布,1993年更名为“Vi iMproved”。
  • Vim在继承vi模式的同时,增加了Unicode支持、扩展正则表达式、自动补全、语法高亮、图形界面、多窗口、标签页、插件系统等功能,逐渐发展为功能强大的编辑器。

Vim的现状与影响

  • Vim仍是活跃开发的项目,拥有庞大社区,是许多Linux发行版的默认编辑器。
  • 通过VimScript和第三方插件,Vim可扩展为高度定制的编程环境。
  • Bram Moolenaar持续维护Vim直至去世,其工作以及之前的开发者共同奠定了现代计算工具的基础。
