[原]无题
年底了，很多地方都要写份年终总结，似乎我也脱不了俗，除了要应付单位那一份外，自己还得整一份，真是把贱骨头。本想把题目定为类似于“2009年终总结”比较正式或者“不是总结的总结”一类比较标新立异的，但是想想还是算了吧，毕竟这是个人的Blog，没必要整的太官样化了，最后，实在没想到更好的标题，于是用了一个万能的标题：“无题”。
前几天我妈跟我MM聊天的时候说了一句精辟的话：“又怕死，又想当官”，用在某些在其位不谋其职的人来说，实在是太精辟了。
今年最大的成绩我估计就是考取了 OCP ，虽然还差一门培训，在整个备考的过程中，我MM给予了我很大的支持，太激动了，这样的MM，实在找不出什么词来形容了。
12月27号通过OCP考试之后，发现变得迷茫了，可能是一下从紧张的状态转入放松的状态吧，非常不适应，真是贱骨头啊，于是乎找来OCM的考点，作为今后自己研究的一个大纲：

也许这辈子都没有机会考取OCM，但是，目标和希望是不应放弃的。
考完试后有点闲，于是乎又在构建我心目中的数据仓库，于是捣鼓起SSIS，希望以此作为ETL工具来使用，希望在2010年中，SSIS能成为我的好帮手吧。
Perl这个被人称为巫师语言的东西，终于入门了，虽然现在写出来的程序C味道很浓，不像一个酷毙了的Perler，但是它的确成为了我的好帮手。
2009年工作中遇到挺多不顺心的事情，特别是负责邮件系统之后，用户迁移，RHCS的集群，乱七八糟的事情一大堆，维护一套邮件系统比起维护5套数据库系统还要头痛，对于这种核心的系统来说，选用第三的产品真的很头痛，第一几乎没有文档可以像Oracle那样研究内部运行机制，第二，出了问题只能找开发商，如果开发商因为这样那样的问题拖着的话，基本上就只能拖着了，第三，日后维护只能找同一家开发商了。其实 MS 的 Exchange 挺不错的，第一，有文档，哪怕不能研究内部运行机理，最起码也能借助Google和baidu解决，第二，服务可以外包，这家不行，可以找另一家。
老家起房子了，加上考OCP，基本上把我的积蓄挖光了，基本上整个下半年，工资卡里的钱都没几天是上千的，有可能是这个原因吧，终于激发了我对现在薪酬的不满，其实不满一直都有了，只不过没有这段时间这么强烈，也许跳槽的时间快到了。还记得第一份“工作”，是在电信实习，由于电信不跟我签约，我不得不跳槽，这是我第二份工作，我自问我做到了“忠诚”，但是现在体会到“忠诚不能当饭吃”那份无奈。
