很久以來，看 yahoo blog 都沒法留言(包括對讀者的意見)。就算登入了 yahoo 帳號也做不到，因為我沒有開 yahoo blog。既然上堂要開 blog，也就當順水推舟好了。

A suggestion for HMAC signature construction
Here is a useful safety tip if you are constructing HMAC signatures for structured messages,things that you want to parse later: put a format version number intoeither the key or the message.
If you want messages in the old format to fail signature checks so thatthe rest of your code doesn't have to deal with them, put the versionnumber into the key.

著名導演楊德昌病逝
這對我來說是一件大事
很喜歡他的電影

香檳氣泡
生命總算是美好的。
午夜，坐在no.9室外的藤椅上。
大雨過後的空氣有點濕潤。
抬頭看著中環的夜景，抬頭看著流動的雲。
這不是墮落，不是浪擲，不是昂貴。
只是奢侈。
呷了一口Moet，氣泡在喉嚨滑過。
我伸一伸腰，對著天空

父權徵兆測試：
此名男子有否事先毫無徵兆地周全照顧地突然打開計程車車門，把你送走。
以上測試可不是我提出的。我只是剛好近來曾經被送過上車而已。

aa | The server is authoritative for the domain. |

ra | The server is willing to do recursive queries foryou. |
tc | The response was truncated because it was toobig to |
How not to set up your DNS (part 15)
This is one of those interesting little DNS glitches:
- the nameservers for the pk country domain say that gem.net.pk lists asnameservers sooraj.gem.net.pk and chand.gem.net.pk.
- if you ask sooraj what gem.net.pk's nameservers are, it gives you anon-authoritative reply saying that they are sooraj, chand, andns1.gem.net.pk.
- ns1.gem.net.pk doesn't respond.
- if you ask
