    无题

      酝酿了两个多月,终于买了辆电瓶车。
      闲聊间,店老板问我是不是做房地产的,我说是写程序的,老板说高科技啊,我说写程序的工作能算得上高科技的只占一小部分...
      在这个急功近利的时代,程序员更多时候东张张西望望,到处找些开源代码拼拼凑凑。"君子善假于物"本是好事,不过大部分时候仅仅只能做到"假于物"而不能做到"善",最终为物所"假",成了没有思想的行尸走肉。而缺乏思考的工作,意义也就只在于混口饭吃。
      前段时间面试了两个人,教育背景都还不错,不过竟然连快速排序的复杂度都答不上来,递归也不会写。不过貌似这样的程序员占绝大多数,也难怪当初奥运的网站如此轻易地挂掉。
      最近一段时间把公司一部分程序进行了优化,这是一项快乐的工作。通过思考和尝试,看到部分程序的效率比原来快了几倍几十倍,让人颇有成就感,也让我回味了当初为ACM疯狂的那段岁月。
      过年的时候为了做一个求导工具用java写过一段解析表达式的代码,写得很急,也就用了2天时间,没有刻意做优化,不过最近找了个开源的比较了一下,自己写的虽然功能稍微弱一点,但解析同样的表达式,在大多数情况下能快5倍多。看来要做适合自己应用的东西,很多时候还是应该自己动手。

    宇平,你写得很有道理。。。。这个世界的人呐

    有那段acm的疯狂岁月应该 是一生难忘的吧,时常想想,鞭策一下自己也很好的!

    我也会经常去回忆以前的疯狂的

    呵呵,我也不懂

    看来我还是应该回去烧煤去

    看始面试别人了,混得不错:)
