Wandering Thoughts | Jan. 25, 2009, 12:18 a.m. | Original

In thinking more about undo issues , I think that thefundamental misconception of designing an undo system is to think of itas purely operation based, instead of something more complex (I don'tthink that it's purely time based either).

酒店和大巴的暖氣把我的臉烘乾至皺皮，敷mask都唔掂，嚇死。後來放棄了搽粉底，每半個小時補保濕gel，情況才好轉

是咁的。

Standby是工作的一部分。

被call了一班我最喜愛的爛機。

提早二十分鐘入briefing room。

"Hi, Im Elaine" "Hi, Im Elaine" 然後坐在一位同事旁邊。

在地獄打了個白鴿轉，

Towards a better undo

Here is my growing theory: current versions of 'undo' functionalitygenerally aren't all that good.
