这是谷歌map-reduce的一个插件，不仅是为了它自己，也是谷歌在不可靠的商品机器农场上运行快速、可靠服务的成就的一个代理。这绝对是一项重要的发明，与1980年主导重量级计算的大型主机方法完全不同。

我相信单元测试、TDD和持续集成是1980年之后的重大发明。

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.")

引用艾伦·凯的话:“预测未来最好的方法就是创造未来。”

互联网。

就是这样。

软件:

虚拟化和仿真 P2P数据传输 社区驱动的项目，如维基百科、SETI@home…… 网络爬行和网络搜索引擎，即索引信息分布在世界各地

硬件:

模块化PC 电子纸

有效的并行化和量子计算——我认为这是两个已经取得进展的领域，而且还将取得更大的进展，从而使我们对计算能力的使用发生重大变化。

有效的并行化意味着在不需要特殊编程技术的情况下并行和分布处理，但将其内置到编译器/框架中。
