An unsurprising discovery about spammer behavior

Here's a recent, not entirely surprising discovery about spammerbehavior: some spammers are really slow to pick up DNS updates.

We changed MX entries to point to our new SMTP frontend on late Monday afternoon. Our MXentries had the standard 24 hour timeout and our secondary servers hadupdated to the new zones by Tuesday morning at the latest, so by nowit is more than two days after our old MX entries were required tohave been purged from caches, even if they were gotten from asecondary using

尊重歷史文化 從保留天星開始 立即停工

民主參與規劃 不容拘捕打壓 立即撤銷控罪


我們是一群關注香港政治、文化和歷史的普通市民。這兩天在天星碼頭堅持不走並獲得一般市民的支持,並非只為保存一件建築物,

心淡

在outport永遠睡不好,在香港永遠不夠時間睡。難得地,今天結結實實的睡了12小時。

然後替友人提早慶祝生日,晚飯後回家。

今夜,被友人責罵,寧願看到我跌跌碰碰但總相信愛情,勝過如今甚麼都放棄還打算掛上價目牌,演活

Fedora Core's memory problem

; chkconfig --list autofs
service autofs supports chkconfig, but is not referenced in any runlevel (run 'chkconfig --add autofs')
; rpm -U autofs*.rpm
[...]
; chkconfig --list autofs
autofs 0:off 1:off 2:off 3:on 4:on 5:on 6:off

到達依靠走動
到達的意義

這改變了衣衫的物料
不再安於表面。

A SMTP implementor's conundrum

Today I ran across a good example of the sort of engineering conundrumthat bedevils people who implement things like SMTP clients:

In a multiline SMTP reply , which replycode should you use if different lines of the reply have differentcodes?

That is, in a regrettably non-hypothetical example, if you send aserver ' MAIL FROM: ' and get back:

250-There's a problem.454 please try later

Should your client go on and send a RCPT TO ,


An example of Unix's slow fossilization

If you walk up to the console of some Linux machines that have theircapslock turned on and try to log in, an interesting thing happens:

keyx login: CKSPASSWORD:[...]CKS@KEYX:~$

(This works with Ubuntu 6.06, but not with Fedora Core 6.)

Why does this happen?

Once, long ago, there were terminals that only did upper case, and therewere people who wanted to connect them to Unix systems. So Bell Labs puta


誠徵 X'mas partner (revised version)

如題。

公司安排了我這顆寂寞芳心23-27號留在香港,那唯一可以做的,就是寫下這篇你正在看的blog。

總覺得傷心就像感冒一樣,吃藥過後,三兩天便會康復。當然,一星期後又可以被人惹病了。

然而,寂寞呢,就像咳嗽。
