这是一个消极的结果，作为一个“基础创新”很奇怪，但我认为适用，因为它开辟了新的研究领域，关闭了无用的领域。

分配共识的不可能性:2001年PODC影响力论文奖

We assumed that the main value of our impossibility result was to close off unproductive lines of research on trying to find fault-tolerant consensus algorithms. But much to our surprise, it opened up entirely new lines of research. There has been analysis of exactly what assumptions about the distributed system model are needed for the impossibility proof. Many related distributed problems to which the proof also applies have been found, together with seemingly similar problems which do have solutions. Eventually a long line of research developed in which primitives were classified based on their ability to implement wait-free fault-tolerant consensus.

The mouse - There have been posts about human interaction. To me, the mouse was the gateway to human interaction. Without it, we'd still be typing and not clicking in dragging, even with our fingers. GUI - Complimented the mouse perfectly. I work in an environment where an as400 is the backend of one of our major apps. Yeah.. Interesting stuff but it just reminds me of the screens 'Bill Gates' is working in in the movie 'Pirates of Silicon Valley' even though that's not what it was. To me, 1 and 2 are the reason anybody, including grandpas and grandmas can use a computer. Excel / spreadsheets - Someone mentioned this before but it's work mentioning again. It's so user friendly and is a great entry point for non-technical users to try their hand at simple programming concepts when performing calculations on cells. Granted it came out before 1980, but the versions post 1980 are when the technology in spreadsheets evolved. Internet (of course) - Not sure how people wrote code without it! Don't flame me for repeating because this belongs on every list. INTELLISENSE - LOVE IT LOVE IT LOVE IT!!!!

几乎是现代3D计算机图形学中所有重要的东西。射线追踪(在计算图形意义上)是从Whitted 1980年的论文开始的。行军立方体('87)是从3D数据中提取等值面的标准方法。

1980年1月2日我开始编程。我试着思考在我的职业生涯中有哪些重大的新发明。我很难想出一个。大多数我认为重要的东西实际上是在1980年之前发明的，但直到1980年之后才被广泛采用或改进。

Graphical User Interface. Fast processing. Large memory (I paid $200.00 for 16k in 1980). Small sizes - cell phones, pocket pc's, iPhones, Netbooks. Large storage capacities. (I've gone from carrying a large 90k floppy to an 8 gig usb thumb drive. Multiple processors. (Almost all my computers have more than one now, software struggles to keep them busy). Standard interfaces (like USB) to easily attach hardware peripherals. Multiple Touch displays. Network connectivity - leading to the mid 90's internet explosion. IDE's with Intellisense and incremental compiling.

虽然硬件有了巨大的进步，但软件行业一直在努力跟上。我们比1980年领先了几光年，但大多数改进都是改进，而不是发明。自1980年以来，我们一直忙于应用技术进步，而不是发明创造。就其本身而言，这些渐进式的发明大多不重要或不强大，但当你回顾过去29年，它们相当强大。

我们可能需要接受渐进式的改进并引导它们。我相信真正原创的想法可能会来自很少接触计算机的人，而且他们越来越难找到。

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。

万维网已经被告知了，但更基本的，我会说“DNS”。 似乎它是在1983年发明的(http://en.wikipedia.org/wiki/Domain_Name_System)，恕我直言，我们可以认为它是互联网协议的发明和传播到世界各地的能力之间的强制性联系，现在被称为网络。

还是在“网络”部分，我要加上WIFI。它是在90年代发明的(但我同意它不完全是“计算”，而更多地与硬件有关)。

在更严格的“算法”部分，我想到了turbocodes(1993年);有人说它只是接近了香农信号理论所定义的极限，但这种论点难道不会否定所有其他对“一切都已经在洛夫莱斯、巴贝奇和图灵的作品中萌芽”的回答吗?

在密码学领域，我想加上P.Zimmermann(1991年)的PGP程序，它为公民带来了一个相当健壮的(当时)免费加密程序，并有助于动摇政府对加密的立场。事实上，我认为这是密码学“自由化”的因素之一，这是发展电子商务的前提。
