第一个demo还真很有意思的。试了一下,居然真的能突然将阅读速度提高约2倍。眼睛好像不听使唤地在飞呐。
其实这些tool都是基于一个理论,就是不是你读得不够快,而是你的眼睛移动得不够。
这个理论在http://en.wikipedia.org/wiki/Speed_reading。 其中加快扫文用的方法是chunking 和skimming.
但是其实要加强理解的阅读,就没有那么简单。需要在字间扫动的同时,集中思考,因为大脑思考停留的时间越长,就把文字形象化,也就理解越深,在脑子里留下的内容和细节就越多。光是加快扫动的速度并不能有效地提高有理解度的阅读速度。
本人从小阅读很差。连读读中文都读不力气。总是默读出声,还常常按自己的意会去乱理解。>,< 不知道是态度不端正还是脑子哪块没有发育好呢?@,@

Doxygen
Generate documentation from source code
Doxygen is a documentation system for C++, C, Java, Objective-C, Python, IDL (Corba and Microsoft flavors), Fortran, VHDL, PHP, C#, and to some extent D.
http://www.stack.nl/~dimitri/doxygen/download.html#latestsrc
----------------------
Install the Doxygen, add the project path of Visual Studio 2010, then it will generate the documents. great software :)
