在主流计算中，有一件事没有改变，那就是分级文件系统。在我看来，这是一种耻辱，因为在20世纪80年代末和90年代，一些工作已经完成，以设计更适合现代面向对象操作系统的新型文件系统——那些从头开始就是面向对象的操作系统。

OO操作系统倾向于具有可扩展且灵活的平面对象存储。我认为EROS项目就是围绕这个想法建立的;PenPoint操作系统是20世纪90年代的面向对象操作系统;Amazon S3当然是当代的平面对象存储。

在面向对象的平面文件系统中，至少有两个想法是我特别喜欢的:

The entire disk was essentially swap space. Objects exist in memory, get paged out when they are not needed, and brought back in when they are. There's no need for a hierarchical filesystem that's separate from virtual memory. Programs are "always running," in a sense. A flat file/object store allows content to be indexed and searched, rather than forcing the user to decide -- ahead of time -- where the content will live in relation to other content and what its name shall be. A hierarchical system could be built on top of the flat storage, but it's not required.

正如Alan Cooper在他的书《About Face》中所述，分层文件系统是一个拼凑物，是为20世纪60年代和70年代内存和磁盘存储有限的计算机设计的。可悲的是，Windows和Unix的流行保证了分层文件系统的主导地位。

“奇点”，以及所有类似的项目，即用托管代码开发操作系统。

有目的的游戏——像Luis von Ahn和他的团队正在开发的集体智慧工具在1980年之前可能是一个梦想，但当时没有一个广泛部署的网络，可以容纳数百万人，并且需要(例如reCAPTCHA)来实现它。

Eclipse IDE

将Smalltalk这样的IDE带给大众;)

标签，信息分类的方式。是的，就是每个问题下面的小方框。

令人惊讶的是，标签发明花了大约30年的时间。我们使用了目录和目录;我们使用了为印刷书籍优化的东西。

然而，30年比人们意识到印刷书籍可以用更小的格式的时间短得多。人们可以把书放在手里。

我认为核心CS玩家低估了标签概念。所有的研究都集中在自然语言处理(自顶向下的方法)。但是标签是第一种计算机和人类都能很好理解的语言。这是一种自底向上的方法，使计算机使用自然语言。

我认为没有什么重要的东西被发明出来。但自80年代以来，人们对软件的看法发生了很大变化。那时有更多的理论家参与其中，现在你在一个程序员论坛上问这个问题。

当时的大多数想法都没有得到实施，或者即使实施了，它们也没有任何真正的重要性，因为当时的软件行业还不存在，市场营销、人力资源、开发阶段或alpha版本也不存在:)。

Another reason for this lack of inventions is the fact that most people use Windows:) dont get me wrong, i do hate M$, but look at it this way: you have a perfectly working interface, with nothing new to add to it, maybe just some new colored buttons. Its also closed enough so you wont be able to to anything with it without breaking it. Thats why i prefer open apps, this way you get more "open" people, to whom yo can actually talk, ask then questions, propose new ideeas that actually gets implemented, or at least put on an open todo-list, thus you get some kind of "evolution". You dont really see anything new because you are stuck with the same basic interface "invented" lots of years ago... did anyone actually tried ION window-manager in a production environment? It has a new kind of interface, and actually lets you do things faster, event it it looks quirky

M$, Adobe..you name it,holds lots of patents so you wont be able to base your work on them, or derivatives(you also wont know what kind of undeveloped tehnologies they hold). Look at MP3 and GIF as examples( i belive that they are both free formats now, but they are also kinda dead..) MP3 is the 'king' of audio evend if there are few algorithms out there much better that it..but didnt get enough traction because they weren't pushed on the consumer market. The GIF... come on, 256 colors??? From this point of voew i'm curios how many people from this thread are working on something "open" that will get to be reused in some other projects, and how many on "closed", protected by NDA's projects?

即使这听起来有点像“免费的威利”，但在80年代，软件是免费的，所有东西都有文档，所有硬件都更简单，更容易使用……同时也更加有限，所以人们并没有浪费时间去执行3d游戏或网页，而是致力于真正的算法。
