哲學,一個危險的學科

哲學要人自省,卻往往令人自大。

哲學的一個目的是訓練人思考清晰,但很多人讀了哲學後頭腦反而越來越糊塗,而且是越糊塗越不知道自己糊塗到甚麼程度。

其他的學科,即使讀不好、讀不上,讀過幾年後或多或少也會學到一

海港城的best kept secret

一般不會為看煙花而出外和人家迫,但今次例外。

上個月,有朋友為參加我的婚宴,專誠遠道從美國回港,我這位移民廿多年,已有資格自稱老華僑的老友,為了想給他今趟旅程一個美好回憶,我便趁適逢東亞運動會開幕典禮這

Local CAs and an interesting consequence of the SSL security model

Suppose that your organization creates an internal organizationalCertificate Authority, so that it can issue SSL certificates for strictly internal hostnames .

I suspect thatthis is a not uncommon setup in sufficiently large companies.

It's recently struck me that this has an interesting consequence: yourcompany security and firewall


Colic

Preparedness is no laughing matter. It's real. Just when I think I've read up and prepped myself on a subject, the real thing will happen exactly.

To give you a little bit of the idea, I would say it's just like looking into a crystal ball. I believed that I should take a good look at Dr. Spook's Baby and Child Care yesterday; I then read the advice how to nurse and breast-feed a baby when the mother is ill. This

我和神的對話 (之二)

不許人間見白頭

有些事情,年輕人是不會相信自己無法理解的,一個不斷在接受教育,知識每日都在增長的年輕人,到了一個年紀,自會認為已經看透很多事,所以前輩們的那一句「你大個自然會明白」,怎麼聽都是很礙耳,他是不會相信的。

幾個月前在 Facebook 出了一句上聯,看看有沒有朋友對到:
