7 年 pb

会点c++ pb搞不定的用他来写动态库（主要这用途）

数据库主要用sqlserver，设计用powerdesigner

其他的语言 java ，net ,delphi 都会点这些主要做些周边的产品，不算精通

发觉深圳呆的很不习惯，没热干面吃嘿嘿，好久没见过雪怪想滴

兄弟门说说武汉滴 pb咋样？

pb现在是不行了大都是小公司用，换其他的语言把舍不的，想想用pb很快就搞定了还费那劲干吗呵呵惰性

看看武汉有大点的公司用pb的没？福利如何调查调查

对于武汉，那是我的家。我工作算来也十年了，外地工作了近八年，工作己经稳定下来。经常在心里对自己说“好想回武汉！”，钱真的是赚不完的，可是家只有一个，要是回武汉我还能做什么呢？想改行自己创业，有这种想法的武汉的兄弟们，大家交个朋友，为我们回武汉谋个出路吧，

主要想回去，对深圳的灯红酒绿高节奏厌烦了还是比较喜欢大热天晚上光膀子座马路边边吃火锅边吹牛
呵呵

上周去深圳，又热又闷，赶上修地铁，路况很差。

出租车挑活，难道不怕投诉么？
