Why I hate firewalls, especially stateful firewalls

I hate firewalls because every firewall between two machines trying totalk to each other is another place for things to go wrong, which meansanother place to check (somehow) when things do go wrong.

評遊戲評

今期 e-zone 的遊戲介紹:

(一) Bioharzard Wi 版評論

優點:遊戲內經常要開槍射擊敵人,玩家雙手休息的時間並不多,久而久之,必定可以鍛練出強壯的手臂。

簡直是任何 Wii 遊戲都適用的評語,而且這是優點?

(二) Tomb Raider Anniversary 評論

然而,錯


Why you want a filesystem consistency checker

Filesystem consistency checkers have historically had three overlappingpurposes:

  1. to patch up the damage done when a machine was shut down partway through modifications to the filesystem.

  2. to find and fix up problems caused by corrupted disk blocks(whether they're caused by a dying disk, a controller error thatscribbled random data on a track, or whatever).

澳門不再悶,可以嗎?

在生活中,看到了弔詭。

這十多個星期以“點解澳門咁Q悶”為題,思考生活在這小城的根本概念。這一系列的文章,每寫一篇都有若干遺憾,我試圖以一個土生土長澳門人的角度去點出同代人可能遇到的問題,卻找不到答案。

為六四寫了詩,編輯的意思是寫給天安門母親。到後來,我終於恍悟,在這種情況下,我不可能寫出獨當一面的詩、在處理某個題材上達到某個高度的詩。要看好詩,看看後面引的廖偉棠和多多吧。我想有了歷史背景,應該可以

RPM's multi-architecture file ownership problem

An increasing number of Red Hat/Fedora machines are dual architecture:they run both 64-bit and 32-bit x86 programs, and thus need to haveshared libraries and RPMs and so on for both of them. This canexpose some interesting issues when installing and upgrading RPMs;one of them is the dual architecture file ownership problem.

There are a lot of RPMs that install both architecture-dependent fileslike binaries and shared libraries and architecture-independent fileslike header files and manpages. The

給星期日明報趕六四稿,從來沒有趕到這個地步,擬不了題連看從頭至尾一次也沒時間、自己也心驚。之前起筆時很順,卻一瀉千里無可收束,馬上就超字了,要刪也不知怎麼刪起—

生活誌


最近“寂然世界”更新慢了,一來是因為家中電腦壞了,二來是我工作忙得要死,三來是我有時間即用來陪家人,於是,生活似乎又“正常”了不少。

寫blog是很自由的事,有話則長無話則短,如果連這個私人空間都有太多硬性規
