即时消息已经出现很长时间了(60年中后期)，但是IRC在1988年之前还没有出现。

除此之外，视频通讯(比如，Windows Live Messenger，或Skype，或……)确实改变了我们的沟通方式;)而且是最近才出现的。

请再次查看恩格尔巴特在1968年演示的内容(包括实时视频聊天和屏幕共享)。低，猜测真的没有查东西管用。这就是为什么大多数人对事物的发明时间做不充分的假设。)

把它放在我的脸上;)，这是理所当然的。

注意:那个时代的“网络摄像头”(视频设置)并不是为普通的客厅设计的;)

网络摄像头替代文本http://wpcontent.answers.com/wikipedia/commons/thumb/c/c5/Logitech_Quickcam_Pro_4000.jpg/180px-Logitech_Quickcam_Pro_4000.jpg的推广也有帮助(始于1991年，第一个这样的摄像头，称为CoffeeCam，是针对剑桥大学计算机科学系的特洛伊房间咖啡壶)。

所以:80后:2 / 3:IRC和网络摄像头。

我们需要的是重组，而不是再造。

我们现在拥有所有我们需要的硬件和软件组件，在未来几年里做一些令人惊叹的事情。

我相信科学中有一种疾病，参与者总是试图发明一些新的东西来区别于别人。这与做一些编目或教授旧作品的混乱工作形成了鲜明对比。

建造“新”东西的人通常被认为比重用现有的和几乎古老的作品的人有更高的血统。(对于一个20岁的年轻人来说，Lisp的开发时间是他们生命的两倍还多。1958)

好的旧想法需要复活并广泛传播，我们需要停止试图建立企业或程序员运动，有效地践踏旧的作品和系统，在权力游戏中成为下一个新事物——事实上，大多数“新的闪亮”事物只是旧想法复活的方面。

采用面向对象。

这个想法早前就出现了(例如Simula)，但在20世纪90年代成为主流。(恕我直言，它最大的好处之一是在开发人员之间提供了一个通用的词汇表，所以它的广泛采用使它更有价值。)

更好的用户界面。

今天的用户界面仍然很糟糕。我指的不是小的方面，而是大的、基本的方面。我不禁注意到，即使是最好的程序也仍然有一些接口，这些接口要么极其复杂，要么需要以其他方式进行大量的抽象思考，而且无法达到传统的非软件工具的易用性。

诚然，这是由于软件可以比传统工具做更多的事情。但这不是接受现状的理由。此外，大多数软件都做得不好。

In general, applications still lack a certain “just works” feeling are too much oriented by what can be done, rather than what should be done. One point that has been raised time and again, and that is still not solved, is the point of saving. Applications crash, destroying hours of work. I have the habit of pressing Ctrl+S every few seconds (of course, this no longer works in web applications). Why do I have to do this? It's mind-numbingly stupid. This is clearly a task for automation. Of course, the application also has to save a diff for every modification I make (basically an infinite undo list) in case I make an error.

解决这个问题其实并不难。在每个应用程序中都很难实现它，因为没有好的API可以做到这一点。编程工具和库必须显著改进，才能在所有平台和程序上轻松实现这些工作，适用于所有具有任意备份存储且不需要用户交互的文件格式。但在我们最终开始编写“好的”应用程序而不仅仅是足够的应用程序之前，这是必要的一步。

I believe that Apple currently approximates the “just works” feeling best in some regards. Take for example their newest version of iPhoto which features a face recognition that automatically groups photos by people appearing in them. That is a classical task that the user does not want to do manually and doesn't understand why the computer doesn't do it automatically. And even iPhoto is still a very long way from a good UI, since said feature still requires ultimate confirmation by the user (for each photo!), since the face recognition engine isn't perfect.

上世纪八十年代初，施乐帕洛阿尔托研究中心对计算机蠕虫进行了研究。

摘自John Shoch和Jon Hupp的“蠕虫”程序——分布式计算的早期经验”(ACM通讯，1982年3月，第25卷第3期，172-180页，1982年3月):

In The Shockwave Rider, J. Brunner developed the notion of an omnipotent "tapeworm" program running loose through a network of computers - an idea which may seem rather disturbing, but which is also quite beyond our current capabilities. The basic model, however, remains a very provocative one: a program or a computation that can move from machine to machine, harnessing resources as needed, and replicating itself when necessary. In a similar vein, we once described a computational model based upon the classic science-fiction film, The Blob: a program that started out running in one machine, but as its appetite for computing cycles grew, it could reach out, find unused machines, and grow to encompass those resources. In the middle of the night, such a program could mobilize hundreds of machines in one building; in the morning, as users reclaimed their machines, the "blob" would have to retreat in an orderly manner, gathering up the intermediate results of its computation. Holed up in one or two machines during the day, the program could emerge again later as resources became available, again expanding the computation. (This affinity for nighttime exploration led one researcher to describe these as "vampire programs.")

我还会推荐3D鼠标。从20世纪90年代初开始就有几种变体。对于任何使用3D的人来说，像spacenavator这样的东西让生活变得更容易。(免责声明:我与3Dconnexion没有任何关系，只是一个满意的无rsi用户。)
