Grady Booch: What should today’s students study more?
I’ll answer that question in two ways. From the lens of software, any good course of study will teach you the basic skills of programming and design. However, I’d recommend three things: learn how to abstract, learn how to work as part of a team, and study the code of others. From a wider lens, I urge students to pursue their passion with abandon, but never forget the value in growing as a whole person.
Study outside your domain (there’s more to the world than software), develop the ability to continuously learn (for this field will continuously change), and fan your spark of curiosity and risk taking (for from such things comes innovation).

软件开发者应该多读代码。
Grady Booch: Speaking of writing, a question I often ask academics is, “How many of you have reading courses in software?” I’ve had two people that have said yes. If you’re an English Lit major, you read the works of the masters. If you want to be an architect in the civil space, then you look at Vitruvius and Frank Lloyd Wright and Christopher Rennin and Frank Gehry and others. We don’t do this in software. We don’t look at the works of the masters. I encourage people to look at the work others have done and learn from them.

程序内部的状态越少越好,集群系统中的分布式状态很难维护,广域网情况下维护在多个节点上的状态更是没什么用。

WiX (Windows Installer XML) 是一个不错的Windows 安装包生成工具,用 XML 文件来控制打包的流程,功能强大,灵活性非常强。MS Office 2007 和 TortoiseSVN 的安装包都是用它做的。只是据说学习曲线比较复杂,我们的 1.0 版本可以用它来打包。

读到一句话:Fonts convey emotion, style and help your writing convey implicit meaning.
作者对比了几种字体的效果,说明了不同的字体表达出不同的内容。初步结论便是:字体(font-family)的选择是很重要的。
