大机学习进行到第二周，只有我，tdy还有lw三个人还在继续学习大机了。李博博突然人间蒸发，julyforce那边杨博和lyf都没有来了。
我不喜欢喊口号，因为喊口号虚张声势居多，对于说的话，立的言，敢不敢较真呢？
学到第二周，每天的联系逐步加难，但模式都是一样的，一个数据集输入进来，他的布局是怎样的，读入以后进行一定的处理，然后打印到新的数据集里面去。
我们继续上大机课的几个人中，lw是最勤勉的，每天都去听课，我是第一周基本都去了全天，这一周上午都没去，下午直接上机，tdy则相反，上周几乎没去，这周一两次全天。不过到下午上机，基本上学的也就搞清楚了。下面贴一个这几天作业中的一个：

不得不提的是有次我提交了个死循环，害得大家甚至彭老师堵了半天不能提交作业，我费了好大劲才把这个死循环给p掉。
那程序基本上参考lw的，不同的是他打到log躲过一劫，我直接打到文件了。。。。。。
用多了大机终端会产生一个毛病，喜欢按F7,F8来翻屏幕，喜欢按f3来退出。。。比如刚才我就是如此。。。
