那些年我們賺過的外快

可能童鞋們都看到園子里有很多大神，賺錢快又輕松。這里我們討論下苦逼程序員如何增加自己的收入。像xiaotie啊、吉日啊這些個前輩是怎么做到的呢？你們想過沒有！當然我也是苦逼大眾之一，還沒到達那境界，我作個簡單分析。然后分享一下最近5、1期間一次技術救急的經歷，分享一下自己做私活的心得。

成功沒有捷徑，因為專業，所以出色！

1、做軟件多年明白一個道理：需求很值錢，業務很值錢。

比如我以前是做酒店管理系統、餐飲管理系統、桑拿收銀系統等等，這些國內信息化比較早的傳統管理軟件。這些軟件能夠成就北京中軟、泰能、杭州西湖軟件等上市公司，還有無數的中小軟件作坊。所以專業的管理軟件必須體現那個行業的先進的管理理念、實現先進的管理方法，能夠提高客戶的收益，提升客戶的管理水平。所以說需求很值錢，業務很值錢。悲劇的是，我沒進到做這些系統的大公司，我入行時那公司只是作坊的規模。所以就悲催了。但是因為在這個行業做了幾年，積累了些人脈，后面換工作因為熟悉這個行業的一些需求、業務，找到了項目經理、產品經理的職位。所以大家不必死死盯着最新的技術，術業有專攻。當你在某一領域做到最專業最有名就成功了。xiaotie是圖像界泰斗，吉日是權限方面的專家，還有像老魏啊醫療HIS方面的、企業級快速開發平台等領域...

一個有趣的現象，同樣是程序員：

一些人累得半死，一個月賺不了多少。有些人很輕松依靠自己的獨門絕技，悶聲發財,關鍵還有時間找妹紙。

對於這現象我也是只有驚嘆，人和人怎么就那么大區別啊！不科學啊！%……&%￥###

2、機遇很重要，人脈很重要。苦逼碼農你要寫博客，多看牛人的博客。

訂閱園子優秀博客的rss以來這幾年逛園子的習慣讓我增長了知識，拓寬了眼界，還有幸結識了一些大牛。苦逼碼農要想發展好，必須注重建立自己的圈子。對，圈子！君不見牛人換工作都是獵頭自己找上門來，成功的碼農跳槽都是朋友推薦，同樣做外快也大都是自己圈子里朋友介紹，或者是人家看了你博客找到你。精明的商家已經學會了微博營銷，碼農你要寫博客，你也可以實現博客營銷。吉日大哥一句話驚醒夢中人：這幾年一寫博客，每年就增加10萬收入！當然我不是在這里找抽，拜金。一個碼農不能養家糊口，算什么英雄。在天朝你沒買房買車，你得不到尊重！

3、個人一次技術援助的分享。

五一前，有位帥哥：山東日照做計生軟件的李哥。通過看我的博客，認為我能解決他遇到的條形碼打印的問題，通過QQ要求我加他。他說可以付費請我幫忙。先是加了他，然后遠程協助了一下，寫了一段代碼那條形碼打印機有反應了，但是打出來東西是空白。無奈那東西需要大量調試，那廠家提供的SDK也只有VB和Delphi、VFP等的。沒有C#的。我使用的是GDI+進行測試，跳開了使用廠家SDK的辦法。但是證明不行，那么只有把Delphi的DEMO轉成C#的一條路了。我說必須多次調試，沒有打印機。李哥二話不說，網上訂了打印機，第二天就到了。李哥老問多少錢，我出於有研究的興趣一直沒答復他，我說簡單的話就免費了。剛好放假有時間花了一天時間搞定了。在通知李哥前，他QQ上留言給我寄了點心意，我擦，山東李哥真豪爽！李哥的答謝禮是一台台電4核的平板電腦！價值1300多！估計李哥是看我說說你們照片發現最近在學安卓開發吧。無圖無真相，上圖得瑟下！
