Simple mailing lists: an illustration of Exim's flexibility

In PostfixVsExim I wrote that Exim is the better mailer if you want todo complex (even crazy) things, because it is more a mailer constructionkit than a mailer (with fixed, pre-existing features). For the benefitof people who haven't been exposed to Exim, I thought I'd illustratethis with one of the things we did in our local Exim configuration.

We have a long-standing system of simplemailing lists. These lists are nothing more than user-owned filesin


更換兒童拍攝模式的動畫—Samsung ST-550

有網友問我,啟動這部Samsung ST-550 DC仔的兒童拍攝模式時,在前面屏幕出現的動畫可否更換,當時我說不可以,我仲寸人細蚊仔同小動物邊識嫌悶?

後來,我發覺我錯了,查實第一個睇厭了同一條動畫轉來轉去的,是我自己。

Touring Roma (Day 2)

Photos : View a gallery of photos from my 2nd day touring Roma .

These crazy little buggers are everywhere. It's always an ordeal to tell which way is on, and which is off, because in Italy, I don't know if


面對歷史的時候


看龍應台的《大江大海一九四九》,沒有理由不問一問自己及家人:六十年前,我們家中的先輩,在做著什麼?

那天我們在讀書會談這本書,我問與我們分享此書的朋友:這本書對澳門有什麼意義?有沒有想過六十年前的澳門是

The case against backup MXes

The usual case against backup MXes isthat they cause backscatter and they have less or no anti-spamprecautions. But these aren't inherent problems with the idea of backupMXes, just bad implementations; it's not particularly difficult to dobetter, and anything can be implemented badly.

Of all teachings given by the emotion intelligence guru Daniel Goleman, none is more important than that of the almond-shaped amygdala in an area of the human brain called the limbic system. Disgust, fear and anger, it is said time and again, come from the amygdala which acts like a central alarm system calling for a full-fledged "fight or flight" response.

My recent lectures in Beijing brought back the nineteen-year-old memory of my first (this is my second) visit of Beijing.

我病了

一個人生病的時候,肉體很軟弱,想的盡都是情緒,盡都是低落,不想去思考,只感覺到內心的空洞。

甚麼是內心的空洞?空洞不是無物,不是甚麼都失去,正好相反,空洞是有物,甚至把整個內心都填得滿滿,但卻竟然沒有一
