Is trial-and-error needed to solve Sudoku puzzles ...

... or are you just dumb?

The truth is, most of the time, the latter is true. The vast majority of Sudoku puzzles can be solved by logic, and logic only. When someone claims that a certain Sudoku puzzle cannot be solved unless trial-and-error is used, you can almost be certain that he/she has not tried hard enough (or he/she is just plain dumb).

But there are indeed a small number of existing Soduku puzzles which do require trial-and-error. Read Michael Mepham's Farewell to Ariadne's thread?.

----------

"Ariadne's thread" comes from a Greek mythology in which Ariadne gives a thread to her lover to help him find his way out of a labyrinth.

I only write about Sudoku as a phenomenon. Personally I don't like this game since I hate spending so much time and enduring so much frustration trying to solve the puzzle. I am just too dumb to play this game of logic.

Big laptop for a small lap

Remember the Mini-Me/Yao Ming commerical for Apple's 17"/12" Powerbooks?



Cindy's 15.4" screen Dell laptop arrived yesterday. That commerical immediately came to mind when I put it side by side with my Sony, which has a 10" screen.

鬱金香出土

據聯合報報導,張愛玲散佚小說《鬱金香》出土

小說故事主要圍繞一個大家庭中的女傭金香和富家少爺寶初、寶餘之間的情感糾葛,並貫穿著家族中正房、側室的明爭暗鬥,充滿張愛玲式的「蒼涼」。金香這個名字令人聯想到《秧歌》中在大都市幫傭的月香。參與這篇小說鑒定的上海學者陳子善表示寶初雖然著墨不多,卻有著張愛玲一九五一年離開上海前發表的《十八春》(張愛玲後來改寫為《半生緣》)中主人公沈世鈞的雛形;而《鬱金香》悲劇性的結尾,同樣令人聯想到《十八春》。

《鬱金香》連載於一九四七年五月十六日至三十一日。之前張愛玲才完成電影《不了情》劇本並改寫為小說《不了情》,接著在四月發表短篇小說〈華麗緣〉。當時張愛玲人在上海,如果是冒名之作,張愛玲豈會不抗議。但《小日報》的影響力小,銷量小,這也是大家對這篇作品沒有印象的主要原因之一。但較讓人不解的是,《鬱金香》在一九四八年十一月三日復刊的文藝周刊第一期《海光》上連載重刊,拿《鬱金香》到《海光》重刊的不是別人,即《小日報》的編者黃轉陶。遺憾的是《鬱金香》十一月十日第二期續刊,還未及刊完,《海光》便再度停刊。但《海光》上的作者不乏名人,豐子愷便曾在《海光》發表作品,仍未引起注意,只能說是陰錯陽差,所幸在五十八年後,這篇小說在張愛玲逝世十周年的月份,重見天日。
