阿恆是我近年來一起搞很多 音樂的朋友

我好像試過很少次,
有朋友送上新書(首部作品集)
原來是感覺很暖的。
也加上這書的封面設計及用紙等,
都給我很好的感

放心放心,我唔係要去買Chanel Cartier定Manolo。

Why I like Python's large integer support

The simple explanation of why I like Python's large integer support(somewhat misleadingly called longs for historical reasons) is that theymake it convenient to deal with arbitrarily large binary numbers.These crop up surprisingly often, sometimes because a large bunch ofbits is the natural representation of things like IPv6 addresses, andsometimes because they make algorithms clearer and simpler.

For example, take the job of generating a random password that's drawnfrom a given alphabet. The simple approach to doing this is:

以教育摧毀教育


社會不斷討論教育改革,為的是什麼?是為了讓孩子學更多知識?是為了讓老師教得輕鬆?是希望提高教學質素?抑或是爭取投放更多教育資源?無論是為了什麼目的,教育改革的討論總是沒完沒了,但真正得到改善的事情又往

當一個女人對男人too nice,你只會得到兩種下場 ──

其實,他們第一張專輯的發佈音樂會,我也有幸參與,眨眼已經年多兩年。

堅持全職/兼職做音樂,兩者都絕非易事,所以,對於阿


Random passwords are not necessarily good passwords

I was recently writing a random password generator and in the processit occurred to me that there is an important difference between randompasswords and good passwords, because we mean different things by thoseterms.

A truly random password is one that an attacker can't guess betterthan through random chance even if they know your password generationalgorithm, so that on average they would have to try half of all of thepossible passwords before successfully guessing yours.

(How many possible passwords there are is based on how many bits of


我的新嗜好

我找到了我的新嗜好 ── 美式桌球。

拜託萬千不要問我為甚麼總不找些良家婦女的嗜好。

我不是不愛烹飪編織彈琴,但沒有天份囉。

喂!有冇人想一齊玩呀?

Why SSL and name-based virtual hosts don't get along

Part of validating a SSL certificate is making sure that it is a SSLcertificate for what you are actually connecting to, to avoid thepossibility of a man in the middle attack. SSL certificates for websiteshave a field (the CN portion of the 'Distinguished Name') that names thehost they are for, and so target validation consists of checking thatthe certificate's CN is the same name as the host portion of the URL.

This checking is pretty literally a string compare; the web browserdoes not


iGoogle 飯局之又「呃飯食」

上個星期有關 Google 的晚餐,我是坐在台灣的 Google 工程師 Ray 的那一桌上,所以也要用不太靈光的國語交談,所以話也不多。內容大概如下 (排名不分先後,只是記憶所及):
