    1. This problem was no secret. Computer scientists had been working on ways to network computers as early as 1962. Then on October 29, 1969—only a few months after Apollo 11 landed on the moon—grad student, Charley Kline, sent a message from his computer at UCLA to a computer some 350 miles north at the Stanford Research Institute (SRI). To Kline and his co-conspirator, Bill Duvall, it was no big deal. “It was just engineers working,” said Leonard Kleinrock, a pioneer of computer networking and a leader of the project.

      这个问题并不是什么秘密。早在1962年,计算机科学家们就已经开始研究计算机联网的方法。然后在1969年10月29日,也就是阿波罗11号登陆月球几个月后,研究生查理 · 克莱恩(Charley Kline)从加州大学洛杉矶分校的计算机向北边大约350英里的斯坦福研究所(SRI)的一台计算机发送了一条信息。对克莱恩和他的同谋比尔 · 杜瓦尔(Bill Duvall)来说,这没什么大不了的。"这只是工程师们的工作,"计算机网络的先驱和项目的领导者伦纳德·克兰罗克(Leonard Kleinrock)说。

    1. The show was part of a larger Computer Literacy Project started by the British government and the BBC as a response to fears that the UK was deeply and alarmingly unprepared for the new revolution in personal computing that was happening in America. Unlike most TV shows, the BBC wanted to feature a computer on the show that would be used to explain fundamental computing concepts and teach a bit of BASIC programming. The concepts included graphics and sound, the ability to connect to teletext networks, speech synthesis, and even some rudimentary AI. As a result, the computer needed for the show would have to be pretty good—in fact, the producers' demands were initially so high that nothing on the market really satisfied the BBC's aspirations.

      这档节目是英国政府和 BBC 共同发起的「计算机素养项目(Computer Literacy Project)」的一部分,它们担心英国对当时正在美国发生的个人计算革命毫无警觉和准备。不同于大多数电视节目,BBC 希望在节目中配备一台计算机,该计算机将用于解释基本的计算概念并教授一些 BASIC 编程。这些计算概念包括图形和声音、连接到图文网络的能力、语音合成乃至一些基础的人工智能。也因此,该节目所需的计算机必须相当好才行,以致于市面上根本就没有能实现 BBC 的愿望的产品,无法满足制片人的要求。

    1. 被誉为“笔记本电脑之父”的约翰·埃伦比 (John Ellenby) 在新西兰家中去世,享年 75 岁。《纽约时报》是这么评价 John Ellenby 的:John Ellenby 是一位值得尊敬的科学家,因为他善于把科技产品化。

      埃伦比是一名英国计算机工程师,在著名的施乐帕洛阿尔托研究中心工作期间,他参与研发了 Alto 电脑,之后又开发了一款更具商业竞争力的产品 Alto II。

      离开施乐后,埃伦比创业成立 Grid Systems 公司,与 William Moggridge 合作,研发了全球第一款“翻盖”电脑——“罗盘电脑”(Compass Computer)。这台电脑现在依然被视为是“超越时代”的产品。

      1988 年 3 月份,埃伦比将 Grid Systems 公司卖掉,与儿子创建了手持式平板电脑制造商 Agilis,后来又创建导航与增强现实应用公司 GeoVector。除此之外,埃伦比也在做地理测绘数据,为现在的手机地图积累了大量数据。

      创立 Agilis 公司期间,埃伦比研发了全球第一台小尺寸手持式移动电话。

      笔记本电脑之父 John Ellenby 去世,连苹果和微软都曾“抄”他的产品

    1. Almost every major technological advance of the last two hundred years has taken place with the aid of large amounts of public money and under a good deal of government influence. The technologies of the computer and the Net were invented with the aid of massive state subsidies. For example, the first Difference Engine project received a British Government grant of £517,470 - a small fortune in 1834. From Colossus to EDVAC, from flight simulators to virtual reality, the development of- computing has depended at key moments on public research handouts or fat contracts with public agencies. The IBM corporation built the first programmable digital computer only after it was requested to do so by the US Defense Department during the Korean War. The result of a lack of state intervention meant that Nazi Germany lost the opportunity to build the first electronic computer in the late '30s when the Wehrmacht refused to fund Konrad Zuze, who had pioneered the use of binary code, stored programs and electronic logic gates.

      近两百年来,几乎所有重大的技术进步都是借助于大量公共资金的资助,并在很大程度上受到政府影响。计算机和网络技术是在国家的大量补贴下发明的。例如,第一个差分机项目获得了英国政府 £517,470 的拨款——在1834年这已经是一笔巨款。从 Colossus 到 EDVAC,从飞行模拟器到虚拟现实,计算的发展都依赖于关键时刻的公共研究捐款或政府机构的巨额合同。IBM 在朝鲜战争期间应美国国防部的要求,才建造了第一台可编程的数字计算机。缺乏国家干预导致了纳粹德国在 30 年代后期失去了建造第一台电子计算机的机会,当时德国国防军拒绝资助开创了二进制编码、存储程序和电子逻辑门的使用的 Konrad Zuze。

    1. Smalltalk was a revolutionary system developed by the Learning Research Group (LRG) at Xerox PARC in the 1970s, led by Alan Kay. Smalltalk was comprised of a programming language, a development environment, and a graphical user interface (GUI), running on PARC’s groundbreaking Alto computer. In fact, it is most famous for being the GUI that inspired Steve Jobs when he and a group of Apple engineers visited PARC in 1979. Smalltalk pioneered overlapping windows, popup menus, and paned browsers, all controlled by a mouse. All of these UI elements have come down to us today through systems like the Macintosh and Microsoft Windows. Smalltalk was also one of the earliest, and most influential, object-oriented programming languages, which make up the most dominant type of programming languages today. Object-oriented languages are designed to make it easy to reuse existing pieces of code, but in a flexible way. Python, Java, Ruby, and Objective-C, among others, all owe debts to ideas originally developed in Smalltalk.

      Smalltalk是70年代由Alan Kay领导的施乐公司PARC学习研究小组(LRG)开发的一个革命性系统。Smalltalk由一门编程语言、一个开发环境和一个图形用户界面(GUI)组成,运行在PARC开创性的Alto计算机上。事实上,它最出名的地方是它的图形用户界面,当史蒂夫 · 乔布斯和一群苹果工程师在1979年访问帕洛阿尔托研究中心时,这个图形界面给了他灵感。Smalltalk开创了重叠窗口、弹出式菜单和窗格浏览器,所有这些都由鼠标控制。今天,所有这些UI元素都通过Macintosh和微软Windows等系统传递给我们。Smalltalk也是最早、最有影响力的面向对象编程语言之一,它构成了今天最主要的编程语言类型。面向对象语言的设计是为了使现有的代码易于重用,但方式灵活。Python、Java、Ruby和Objective-C等,都要归功于 Smalltalk 中最初开发的思想。

    2. The Smalltalk Zoo is a collection of historical versions of the revolutionary graphical programming and user environment Smalltalk, originally developed at Xerox PARC, ranging from the 1972 version all the way to the modern “Squeak” version whose development began in 1995. These emulated Smalltalk environments run in your web browser and are hosted by CHM at smalltalkzoo.thechm.org.

    1. A 1971 issue of the radical feminist journal off our backs includes an announcement for a May meeting in Atlantic City “against the misuse of technology.” An announcement for that meeting also appears in a 1971 issue of alternative publication The Realist. There, CPP placed a call for activists to appear at that year’s Spring Joint Computer Conference, an event that the ad points out is “overwhelmingly dominated by white males,” so as to call attention to issues that are critical today — namely, “the use of computer information systems as a means of social control,” “corporate racism,” and “the role of automation on rising unemployment.”

      1971年出版的激进女权主义杂志《远离我们》(off our backs)中有一则公告,宣布5月在大西洋城举行一次 "反对滥用技术"(against the misuse of technology)的会议。那次会议的公告也出现在1971年的另类出版物《现实主义者》(The Realist)中。在那里,CPP号召积极分子出席当年的春季联合计算机会议,公告指出,这一活动 "绝大多数由白人男性主导",以此呼吁人们关注当今至关重要的问题——即 "利用计算机信息系统作为社会控制的手段"、"公司种族主义 "和 "自动化对失业率上升的作用"。
