那些年我们赚过的外快
可能童鞋们都看到园子里有很多大神，赚钱快又轻松。这里我们讨论下苦逼程序员如何增加自己的收入。像xiaotie啊、吉日啊这些个前辈是怎么做到的呢？你们想过没有！当然我也是苦逼大众之一，还没到达那境界，我作个简单分析。然后分享一下最近5、1期间一次技术救急的经历，分享一下自己做私活的心得。
成功没有捷径，因为专业，所以出色！
1、做软件多年明白一个道理：需求很值钱，业务很值钱。
比如我以前是做酒店管理系统、餐饮管理系统、桑拿收银系统等等，这些国内信息化比较早的传统管理软件。这些软件能够成就北京中软、泰能、杭州西湖软件等上市公司，还有无数的中小软件作坊。所以专业的管理软件必须体现那个行业的先进的管理理念、实现先进的管理方法，能够提高客户的收益，提升客户的管理水平。所以说需求很值钱，业务很值钱。悲剧的是，我没进到做这些系统的大公司，我入行时那公司只是作坊的规模。所以就悲催了。但是因为在这个行业做了几年，积累了些人脉，后面换工作因为熟悉这个行业的一些需求、业务，找到了项目经理、产品经理的职位。所以大家不必死死盯着最新的技术，术业有专攻。当你在某一领域做到最专业最有名就成功了。xiaotie是图像界泰斗，吉日是权限方面的专家，还有像老魏啊医疗HIS方面的、企业级快速开发平台等领域...
一个有趣的现象，同样是程序员：
一些人累得半死，一个月赚不了多少。有些人很轻松依靠自己的独门绝技，闷声发财,关键还有时间找妹纸。
对于这现象我也是只有惊叹，人和人怎么就那么大区别啊！不科学啊！%……&%￥###
2、机遇很重要，人脉很重要。苦逼码农你要写博客，多看牛人的博客。
订阅园子优秀博客的rss以来这几年逛园子的习惯让我增长了知识，拓宽了眼界，还有幸结识了一些大牛。苦逼码农要想发展好，必须注重建立自己的圈子。对，圈子！君不见牛人换工作都是猎头自己找上门来，成功的码农跳槽都是朋友推荐，同样做外快也大都是自己圈子里朋友介绍，或者是人家看了你博客找到你。精明的商家已经学会了微博营销，码农你要写博客，你也可以实现博客营销。吉日大哥一句话惊醒梦中人：这几年一写博客，每年就增加10万收入！当然我不是在这里找抽，拜金。一个码农不能养家糊口，算什么英雄。在天朝你没买房买车，你得不到尊重！
3、个人一次技术援助的分享。
五一前，有位帅哥：山东日照做计生软件的李哥。通过看我的博客，认为我能解决他遇到的条形码打印的问题，通过QQ要求我加他。他说可以付费请我帮忙。先是加了他，然后远程协助了一下，写了一段代码那条形码打印机有反应了，但是打出来东西是空白。无奈那东西需要大量调试，那厂家提供的SDK也只有VB和Delphi、VFP等的。没有C#的。我使用的是GDI+进行测试，跳开了使用厂家SDK的办法。但是证明不行，那么只有把Delphi的DEMO转成C#的一条路了。我说必须多次调试，没有打印机。李哥二话不说，网上订了打印机，第二天就到了。李哥老问多少钱，我出于有研究的兴趣一直没答复他，我说简单的话就免费了。刚好放假有时间花了一天时间搞定了。在通知李哥前，他QQ上留言给我寄了点心意，我擦，山东李哥真豪爽！李哥的答谢礼是一台台电4核的平板电脑！价值1300多！估计李哥是看我说说你们照片发现最近在学安卓开发吧。无图无真相，上图得瑟下！
