I'd say the biggest trend is an ever increasing lack of location dependence and pervasiveness. An interesting philosophical exercise these days is to count the computers in you immediate area. They're everywhere desktops, keyboards, microwaves, radios, televisions, cell phones etc... My grandmother computer is illiterate however her life is as infested with small computers as everyone else's. She can make a call to me from the middle of an empty field. I can then answer that call zipping down the highway.

个人电脑。

毫无疑问，在过去的30年里，计算最重要的部分是现在每个人都是它的一部分。家用电脑大约从1977年才开始普及，直到80年代才得到广泛应用。现在，幼儿园、老年中心和你的每个邻居都有一台。

基础设施的改变使家庭和办公室都能接入互联网。

记录并接受了从W3C到api的标准

除此之外，我们所认为的大多数新事物都比你想象的要久远得多(例如GUI, OOP)。

Eclipse IDE

将Smalltalk这样的IDE带给大众;)

Ctrl-C + Ctrl-V + Ctrl-X组合:)

我没有资格在一般意义上回答这个问题，但仅限于计算机编程?并不多。

为什么?我思考这个问题已经有一段时间了，我认为我们缺少两样东西:历史感和客观评价我们所创造的一切的方法。并非所有情况都是这样，但大体上是这样。

For history, I think it's just something not emphasized enough in popular writing or computer science programs. Take language features, for example. A canonical source might be HOPL, but it's definitely not common knowledge among programmers to be able to mark the point in time or in which language a feature like GC or closures first appeared. And of course after that there's knowledge of progression over time: how has OOP changed since Simula? Compare and contrast our sense of history with that of other fields like maybe political science or philosophy.

至于判断，这确实是我们寻求成功的客观衡量标准的失败。给定foobar，它以什么可衡量的方式改进了编程行为中的某些方面，其中foobar是任何设计模式，敏捷方法，TDD等等。我们有没有试过测量这个?我们到底想测量什么?正确性，程序员的生产力，代码的易读性等等?如何?软件工程确实应该着手解决这些问题，但我还没有看到。
