我的GitHub主页上写着加入的时间——``Joined on Nov 8, 2010``，那时才大一，在那之后的那长日子里我都没有过到。也许是因为我学的不是计算机，到了今天——``2015.3.9``，我也发现这其实是程序员的社交网站。

##我与GitHub的故事
|
||||
|
||||
在我大四找工作的时候，试图去寻找一份硬件、物联网相关的工作(ps: 专业是电子信息工程)。尽管简历上写得满满的各种经历、经验，然而并没有卵用。跑了几场校园招聘会后，十份简历(ps: 事先已经有心里准备)一个也没有投出去——因为学校直接被拒。我对霸面什么的一点兴趣都没有，千里马需要伯乐。后来，我加入了Martin Flower所在的公司，当然这是后话了。

这是一个残酷的世界，在学生时代，如果你长得不帅不高的话，那么多数的附加技能都是白搭(ps: 通常富的是看不到这篇文章的)。在工作时期，如果你上家没有名气，那么将会影响你下一份工作的待遇。而，很多东西却会改变这些，GitHub就是其中一个。

注册GitHub的时候大概是大一的时候，我熟悉的时候已经是大四了，现在已经毕业一年了。在过去的近两年里，我试着以几个维度在GitHub上创建项目:

没有测试的项目是很扯淡的，除非你的项目只有一个函数，然后那个函数返回``Hello,World``。
|

如果你的项目代码有上千行，如果你能保证测试覆盖率可以达到95%以的话，那么我想你的项目不会有太复杂的函数。假使有这样的函数，那么他也是被测试覆盖住的。

<p><strong>创造是一种知识的再掌握过程。</strong></p>
|
||||
<p>回顾一下写echoesworks的过程，一开始我需要的是一个网页版的PPT，当然这类的东西已经有很多了，如impress.js、bespoke.js等等。分析一下所需要的功能：markdown解析器、键盘事件处理、Ajax、进度条显示、图片处理、Slide。我们可以在GitHub上找到各式各样的模块，我们所要做的就是将之结合在一样。在那之前，我试着用类似的原理写（组合）了<a href="https://github.com/phodal/lettuce">Lettuce</a>。</p>
|
||||
<p>组合相比于创造过程是一个更有挑战性的过程，我们需要在这过程去设计胶水来粘合这些代码，并在最终可以让他工作。这好比是我们在平时接触到的任务划分，每个人负责相应的模块，最后整合。</p>
|
||||
<p>想似的我在写<a href="https://github.com/phodal/lan">lan</a>的时候，也是类似的，但是不同的是我已经设计了一个清晰的架构图。</p>
