蠕虫与橡皮绳

kaikai摘引的难题,这个爱思考的家伙,可能学生很喜欢。

“一条蠕虫在橡皮绳的一端。橡皮绳长一公里。蠕虫以每秒1厘米的稳定速度沿橡皮绳爬行。在1秒钟之后,橡皮绳就像橡皮筋一样拉长为2公里。再过一秒钟后,它又拉长为3公里,如此下去。蠕虫最后究竟会不会达到终点呢?”—-[从不轻信]

名字和外衣

朋友来信问
为什么中国人那么多名字
我一头雾水
原来他在写网络发展报告
面对真名和网名迟疑

我告诉他中国文化深厚
名讳习惯久已
名字反映素养水平
如“伊人旧相机”多有诗意
从“酱子”到“木子美”到李丽
概念转换还甚为锻炼智力
哪像你们的名字
David, John用的翻来覆去

小论坛时代已经过去
不知是否社会性软件
会让真名实姓更有意义
更盼诚信社会
欺骗、冷箭和焦虑渐息

那夜彩色长梦
梦见身着华丽名字外衣
忽然名字纷纷破碎
剩下尴尬身体 //

More implementations ahead on Grasshopper:
Grasshopper is the codename for RSS spider in Grassland project. It now can manually crawl and fetch a list of RSSs and remotely update Grassland database. However, there are more works ahead to be implemented: 1. Distribute the spider to support multi-point crawling; 2. Timer-control crawling and increamental updating database; 3. Analyze the linked between blogs; 4. Automatically lock database temporarily when updating database; 5. Auto classifying and ranking RSS feeds. I didn’t set priorities in this to-do list, since they seems all important. :)
