很惊讶昨晚写的第一篇学习笔记竟然有个评论了，只是今天还是对基础知识提不起精神，还是先看那三本书了解一下程序开发的大概流程吧。
今天不知道怎么闲逛就找到了这个网站，说是专门用于编程练习的，用google账户就能够登录，简单整理了一下免费版可以直接使用的！如下表：
| 编程语言 | 开源项目 | 代码行数 | 源程序 | |

| C | Redis | 475 lines | Data Structure Server — db.c | |
| C | Linux0.0.1 | 213 lines | Minix-like kernel for i386 — sched.c |
尝试了一下C#的，还真是跟平时打字不同，有点别扭不很适应！这是第一次测试的 Lesson Summary：
| typeable characters | 309 | |||||||||||||
| typed characters | 373 |
|
||||||||||||
| unproductive keystrokes | 21% |
373 typed characters — 309 typeable characters
-----------------------------------------------------
309 typeable characters |
||||||||||||
| elapsed time | 1:50 | |||||||||||||
| wpm | 34 |
309 typeable characters 1
--------------------------- × -------------
5 characters per word 1:50
|
第二次测试，看上去好象是略有提高的样子
| ypeable characters | 376 | |||||||||||||
| typed characters | 438 |
|
||||||||||||
| unproductive keystrokes | 16% |
438 typed characters — 376 typeable characters
-----------------------------------------------------
376 typeable characters |
||||||||||||
| elapsed time | 1:59 | |||||||||||||
| wpm | 38 |
376 typeable characters 1
--------------------------- × -------------
5 characters per word 1:59
|
不过一个486行的文件要打这么久？2次才完成了30行啊：
| 30 | lines typed |
| 456 | lines remaining |
第三次测试，又有所提高，不过呢，厌倦了，就到这吧，看书去：
| typeable characters | 477 | |||||||||||||
| typed characters | 519 |
|
||||||||||||
| unproductive keystrokes | 9% |
519 typed characters — 477 typeable characters
-----------------------------------------------------
477 typeable characters
|
||||||||||||
| elapsed time | 2:14 | |||||||||||||
| wpm | 43 |
477 typeable characters 1
--------------------------- × -------------
