極端


黑白分明是良好的願望。

小朋友看的卡通片,主角好壞分明,絕不混淆。可是現實世界的人和事,除了黑白兩種色,還有沒有別的顏色?

也許是卡通片看得多了,我們身邊總有一些想法簡單的成年人,誤以為小城的大小事務都是

在森林和原野

是的,上文提及那河流就是山下那條可通往北冰洋的葉尼塞河。

Link: Using colour well in data visualization

Why Should Engineers and Scientists Be Worried About Color? is abouthow straightforward use of colour in data visualizations can mislead youand hide information (and how to do better). Some of their examplesare eye-opening and alarming.

Python, signal handlers, and EINTR

One of the interesting effects of setting a signal handler inyour Python program is, well, let me quote the signal module :

  • When a signal arrives during an I/O operation, it is possiblethat the I/O operation raises an exception after the signal handlerreturns. This is dependent on the underlying Unix system's semanticsregarding interrupted system calls.

By 'an I/O operation' the manual means more than you might think; forexample, select.select() is affected by this.


由香港隊晉級國家隊的老友


今次北京之旅,最開心的,除了參加了這個博客論壇外,更開心的,是有機會和一位認識多年的老友聚舊。

我讀大學的年代(即係八、九十年代囉老友,老餅之唔係我),我邊上課邊幫大量報紙雜誌寫樂評及兼職記者,有些沒稿


北京博客論壇—「除了帽子什麽都可以綠」(二)

我們還是預算錯誤了.

昨晚將Ding Ding抱回家後, 與蜜柑碰個正著. 蜜柑五年來幾乎沒有見過自己的同類, 但貓的本能反應仍在. 蜜柑問候Ding Ding的開場白如下:

「Sii....Sii.... Wellaaaaaaaaaaaaaaaaaaooooooooooooohhhhhhhhhhh!!!!!」

蜜柑忽然大丈夫, 由清純笨貓變

Conformist

Not long ago, my wife and I had a dinner in a Chinese restaurant. It wasn't a particularly big one, but it served great dishes. But when I caught my wife's eye, I could see she was feeling tired. Then I started to notice that we were sitting beneath a noisy television, and right next to a busy corridor. You can't think of better way to make people throw a fit. Plus an epileptic fit - if you happen to be sensitive to the flicker
