The reason was that people were thought to sneeze out their souls, and before their souls could get back lurking demons were apt to enter the unsouled body; but if any one said “God bless you,” the demons were frightened off.’ text/html 2008-04-13T10:55:28+08:00 Adrian Tam http://aipl.ie.cuhk.edu.hk/~adrian/doku.php/blog/choileefaat?rev=1208055328&do=diff1208055328 近日在網上找到的片段： <http://www.56.com/w17/play_album-aid-420709_vid-MTM0NDk3MDc.html> 這是一堆蔡李佛拳的演示，都是我之前學過的鴻勝（李冠雄師公流傳下來的）那種。看來像是師公傳到美國去的武館所拍的，不然都不會用英文和廣東話解說。穿拋掛捎插我還記得，但是可惜好像再不能在網上找到拳譜了，勉強只有在大陸見過雄勝門的小梅花拳譜，跟師公的版本有點兒出入。 text/html 2008-04-12T07:58:20+08:00 Adrian Tam http://aipl.ie.cuhk.edu.hk/~adrian/doku.php/notepad/nyc?rev=1207958300&do=diff1207958300 * 紐約有五個區: Manhanttan, Brooklyn, Queens, Bronx, Staten Island * 銷售稅率：8.375%，衣服鞋襪4.375%免稅，bottles/cans再有USD 0.05按樽費 * Skype收費: 每分鐘 HKD 0.166 或 USD 0.021 (等價)，再加connection fee HKD 0.39 或 USD 0.039 (USD較平) * 時區: GMT-4 (三月至十月) 或 GMT-5 (十一月至二月) * 冬令時間(GMT-5)由十一月第一個星期日的2:00am開始 * 夏令時間(GMT-4)由三月第二個星期日的2:00am開始 text/html 2008-04-12T03:31:26+08:00 Adrian Tam http://aipl.ie.cuhk.edu.hk/~adrian/doku.php/blog/zhrecode?rev=1207942286&do=diff1207942286 最近時間分配好像好了一點，所以可以多點做自己的事。其中一件事就是完成zhrecode。 zhrecode是我在CSE時想出來的小工具，但是難度不少。雖然它的作為是替中文作內碼轉換，也就是說GNU iconv和recode都可以做到的東西，但是因為某個笨蛋想出來的漢字簡化計劃，導致iconv和recode都不能完美地作轉換，例如說，把某UTF8內碼的文章，全是簡體字，轉為只支援正體中文的BIG5內碼就有�… text/html 2008-03-28T04:09:40+08:00 Adrian Tam http://aipl.ie.cuhk.edu.hk/~adrian/doku.php/research/graph?rev=1206648580&do=diff1206648580 Jargons * Loop: An edge connecting a vertex to itself * Clique: A loop-free graph with every vertex connect to every other vertex * Vertices of attachment: For a subgraph H of a graph G, the v.o.a. are those vertices in H that have some incident edges in G not included in the subgraph H * Isthmus: An edge in a graph that has one of its ends of degree-1 * Cutvertex: A vertex that its removal will make a connected graph/subgraph disconnected * Bridge: An edge that its removal will mak… text/html 2008-03-15T02:48:23+08:00 Adrian Tam http://aipl.ie.cuhk.edu.hk/~adrian/doku.php/notepad/latex/tricks?rev=1205520503&do=diff1205520503 Text, style and Grammar Grammar check Try Queequeg, <http://queequeg.sourceforge.net/index-e.html> Prevent hyphenation at once \hyphenpenalty=5000 \tolerance=1000 Using limit-mode in summation Force limits to place at above and below (useful for inline equation): text/html 2008-03-14T02:00:29+08:00 Adrian Tam http://aipl.ie.cuhk.edu.hk/~adrian/doku.php/notepad/system/perloneliner?rev=1205431229&do=diff1205431229 Indenting here documents ($blah = <<' ENDHEREDOC') =~ s/^ {8}//gm; blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah ENDHEREDOCalso, it is better to quote the here document tags, so that you can have a semicolon:$blah = <<'ENDHEREDOC'; blah blah blah ENDHEREDOC In other words, get something from a pattern without using substitution: text/html 2008-03-12T23:56:15+08:00 Adrian Tam http://aipl.ie.cuhk.edu.hk/~adrian/doku.php/bookmark/academic?rev=1205337375&do=diff1205337375 * Making an Academic Poster Display Effective Bandwidth and Large Deviation Techniques * The page by Frank P.

He is the greatest Governor ever in the history of Hong Kong, and established a model for a well-performed government. It is a pity that he cannot continue to manage the city and we never have one that can replace him so far (may be due to the sovereignty reason --- you know, all clever people in the communist party are dead!)
