这个问题来自于对过去50年左右计算领域各种进展的评论。

其他一些与会者请我把这个问题作为一个问题向整个论坛提出。

这里的基本思想不是抨击事物的现状,而是试图理解提出基本新思想和原则的过程。

我认为我们在大多数计算领域都需要真正的新想法,我想知道最近已经完成的任何重要而有力的想法。如果我们真的找不到他们,那么我们应该问“为什么?”和“我们应该做什么?”

我想说的是,CDMA是1980年以后产生的一个重要而强大的新概念。

其他回答

过去30年里处理器速度的大幅提升不容忽视。各种聪明的想法,如流水线和抢占式分支,以及处理器设计电子方面的改进,意味着今天的程序员可以更多地担心程序的设计和可维护性,而不必担心计算时钟周期。

有一件事让我吃惊,那就是简陋的电子表格。非程序员的人用一个简单的公式网格就可以为现实世界的问题构建狂野而奇妙的解决方案。在桌面应用程序中复制他们的努力通常需要比编写电子表格多10到100倍的时间,最终的应用程序通常更难使用,充满bug !

我相信电子表格成功的关键是自动依赖分析。如果电子表格的用户被迫使用观察者模式,他们就没有机会得到正确的结果。

因此,最大的进步是自动依赖分析。现在,为什么没有任何现代平台(Java, .Net, Web Services)将其构建到系统的核心中呢?特别是在一个通过并行化扩展的时代——依赖关系图导致并行重新计算变得微不足道。

编辑:我刚查过。VisiCalc发布于1979年——让我们假设它是1980年后的发明。

Edit2:似乎艾伦已经注意到了电子表格——如果让他来这个论坛的问题是正确的!

除了硬件创新之外,我倾向于发现太阳底下几乎没有新的东西。大多数真正伟大的想法都可以追溯到冯·诺依曼和艾伦·图灵这样的人。

如今,许多被贴上“技术”标签的东西实际上只是某人编写的程序或库,或者是用新的隐喻、首字母缩写或品牌名称对旧思想进行翻新。

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。

我认为,在1980年,如果你在使用一台电脑,你要么是在赚钱,要么就是一个极客……那么发生了什么变化呢?

Printers and consumer-level desktop publishing. Meant you didn't need a printing press to make high-volume, high-quality printed material. That was big - of course, nowadays we completely take it for granted, and mostly we don't even bother with the printing part because everyone's online anyway. Colour. Seriously. Colour screens made a huge difference to non-geeks' perception of games & applications. Suddenly games seemed less like hard work and more like watching TV, which opened the doors for Sega, Nintendo, Atari et al to bring consumer gaming into the home. Media compression (MP3s and video files). And a whole bunch of things - like TiVO and iPods - that we don't really think of as computers any more because they're so ubiquitous and so user-friendly. But they are.

我认为,这里的共同点是曾经不可能的事情(制作打印文档;准确再现彩色图像;实时向世界各地发送消息;分发音频和视频材料),当时因为设备和物流成本昂贵,现在是消费者水平。那么,大公司现在在做什么过去是不可能的,但如果我们能想出如何做小而便宜的事情,可能会很酷?

任何涉及物理运输的东西都是有趣的。视频会议(目前)还没有取代真实的会议,但如果技术合适,它仍有可能取代真实的会议。一些休闲旅行可以被全感官沉浸式环境所取代——家庭影院就是一个微不足道的例子;另一个是位于Soho区一栋写字楼内的“虚拟高尔夫球场”,在这里,你可以在模拟球场上打18洞真正的高尔夫球。

不过,对我来说,下一个真正重要的事情将是制造。做的事情。勺子,吉他,椅子,衣服,汽车,瓷砖什么的。这些仍然依赖于生产和分销基础设施。我再也不用去商店买电影或专辑了——什么时候我就不用去商店买衣服和厨具了?

Sure, there are interesting developments going on with OLED displays and GPS and mobile broadband and IoC containers and scripting and "the cloud" - but it's all still just new-fangled ways of putting pictures on a screen. I can print my own photos and write my own web pages, but I want to be able to fabricate a linen basket that fits exactly into that nook beside my desk, and a mounting bracket for sticking my guitar FX unit to my desk, and something for clipping my cellphone to my bike handlebars.

与编程无关?不…但在1980年,声音制作也不是。或者视频分发。或者给赞比亚的亲戚发信息。大处着眼,伙计们……:)
