You are standing in a rectangular room and are about to fire a laser toward
the east wall. Inside the room a certain number of prisms have been placed.
They will alter the direction of the laser beam if it hits them. There
are north-facing, east-facing, west-facing, and south-facing prisms. If the
laser beam strikes an east-facing prism, its course will be altered to be
East, regardless of what direction it had been going in before. If it hits
a south-facing prism... 阅读全帖 |

发帖数: 299 | 8 国人对《魔戒》认识的几大误区
作者：凡夜 发表日期：20040315 22:10:39
首先声明，不喜欢《指环王》这个译名，因此按照中文版图书和港台译法《魔戒》
纯粹是 因为最近看到一些国内所谓的著名电影人或记者什么的对《魔戒》的评论，碰巧
偶心情很好，过来给那些小白老白扫扫盲（其实偶知道那种人根本看不进的啦）……郁闷
之作~了解魔戒的人就不用看了，不过也欢迎一起来郁闷啦~
******************************
误区一：这是是最典型的美国本土大片
这是是最典型的小白！说魔戒是美国本土大片恐怕所有的魔戒迷都会笑掉大牙！影片的导
演，制片，编剧等一干主创人员都是新西兰本土人氏，而各位主要演员则来自世界各地。
影片中那些令人敬佩的特技、替身和群众演员全部都是新西兰的普通民众。魔戒的全片在
新西兰，其中后期制作有些部分在伦敦完成。当年PJ导演带着初步完成的魔戒企划去找米
拉麦克斯公司投资时遭到回绝，对方对PJ将这个故事拍两部的计划不抱以信心，只愿意拍
一部；而当PJ找到当时还是小公司的Newline新线时，新线当即拍板要拍就拍3部。尽管这
样，当初魔戒的预算也只有1亿8 |

still, to my best impression, the Hobbit tastes more like a leftover

a dish:)
The Hobbit is the only movie that I watched struggling to fend sleep.
The overture, hmm, intro has been too long and it mixed with too much
piecemeal actions so that after that long hour, we can hardly remember
any solid main characters. Sorry to character-building.

I try to use longtext for the field. However, if the string
that i create contains
new line, the server fails to accept it. For examples, if i
create a simple GUI
for mail composer, if i want to allow user to type in their
message into textarea and then
use a servlet to fetch the content in textarea as a string,
i am not able to insert

发帖数: 62 | 34 I guess you can do it in the following steps, using shell pipes to connect them.
1. use "sed" to convert the text into a stream of words separated by newline
2. use "sort" to sort the words
3. use "uniq" to count the number of unique words. |

The delimiter character is delim for the first function version, and '\n' (
newline character) for the second. The extraction also stops if the end of

发帖数: 6806 | 41 checked standard. if EOF happens in the middle of a line, you see eofbit
alone. if EOF happens immediately after a newline, a sentry object is
constructed at that time and traits::eof() is returned. and sentry object
set eofbit|failbit.
i think usually badbit alone should be the exception condition. failbit can
happen quite easily. |

如果分隔符不是|而是空格,用
