Multihomed hosts and /etc/hosts

As a side note to looking up hostnames from IP addresses for people who use /etc/hosts , note that /etc/hosts lookups work badly in the presence of hosts with multipleIP address, since most gethostbyname() implementations will onlyreturn the first IP address that they find in /etc/hosts . These daysyou really want a minimal /etc/hosts and a reliable DNS server, unlessyou have special concerns .

(The gethostbyname() behavior is sensible, since otherwise it wouldalways have to


甚麼是鬼?

mad detective

當見到《神探》的神探陳桂彬說他可以見到人們心中的鬼,我即時有這個疑問:甚麼是鬼?

跟據字面的直接解法,我們常說人心中有鬼,似乎想說「鬼」等於是「人的陰暗面」或「心魔」。這符合結尾陳桂彬的自說自話和何家安


Getting a useful persistent VNC session

By a persistent VNC session, I mean a session that you can connect yourVNC viewer to, do stuff, disconnect from, and then later come back toconnect to it again. This makes it the graphical equivalent of screen , at least for me.

(Much like screen , it also gives you a certain amount of immunityagainst network and workstation stability problems for critical tasksthat you don't want interrupted. More and more, systems have to bemanaged graphically instead of through text interfaces, which means that

「泡沫」風波

雖然 Here Comes Another Bubble 在刪除了攝影師 Lane Hartwell 的照片後再上架,但也引來其他攝影師的 質疑 是否應向影片創作者 the Richter Scales 有同樣的要求,刪除相關照片或向他收取費用。

A thought about Solaris 10 x86's boot process

In succinct form:

The problem with Solaris 10 x86's boot process is not so much that itis trying to pretend that it has OpenBoot, the problem is that it isdoing such a clumsy and awkward job of faking it.

I will admit that I am not a fan of the Solaris 10 x86 boot process. Iunderstand why it is trying very hard to pretend that it is just likeSPARC hardware with OpenBoot, and I can even sympathize with Sun'smotivations for

Virtualization does not eliminate security concerns

Here is something that has struck me recently: virtualization andabstraction cannot eliminate security concerns, they can only move themfrom one place to another . In other words, virtualization by itselfdoesn't do anything to prevent security bugs; it just means that theyhappen in a different place.

(By virtualization I mean more than hardware and OS virtualization, Ialso include things like the JVM.)

The advantage of virtualization is that it moves the problem inwards,towards the center of the security onion, where fewer people


無聊計數機玩意

Casio Fx3900Pv

在中學時期,長伴數學課的就是計數機,當時用的型號是 Fx3900Pv,大抵每個人都會用裏面有限的空間來輸入尋二次方程根的數式吧!當時我們有一個玩意,玩法如下:

  1. 兩個或以上人參與, 按數次 AC 清除所有狀態
  2. 1++
