幪面超人劇集內經常行先死先果班二打六壞人，究竟點稱呼？
問過幪面超人專家肥倫，佢好正經咁答我話：「佢地一般被統稱為戰鬥員」，而坊間就向來慣稱他們為Geek Geek，因為佢地出親場，都係Geek Geek聲咁叫。
無諗過呢班Geek Geek都有

有一次在酒樓，旁邊有個女人訂了酒席要擺滿月酒，覺得酒樓沒在原有酒席之外把更多地方空出來（比如訂了十圍，應該另外再空出三四圍的空位去讓地方顯得闊落），大吵大鬧近一小時。聽得裡面有一個說法是「咁出面咁多間
Why high availability NFS requires shared storage
Suppose that you have a situation where you need transparent highavailability NFS for something that is read-only and updated onlyinfrequently. Instead of going to the expense and bother of settingup real shared storage, it's tempting to try to implement this bysetting up a number of fileservers with local copies of the filesystem,synchronizing it from a master machine with rsync , and then using aslight variant of the basic HA NFS setup .
Unfortunately, the tempting easy way doesn't work; you can't
The inner life of NFS filehandles
The NFS protocol uses something called a 'file handle' to identifywhat file a given operation applies to; this is sort of analogous tohow a traditional Unix system internally identifies files by theirinode number (well, their device plus their inode number).
In theory a NFS filehandle is opaque and an NFS server can use anyscheme it wants in order to uniquely identify files. In practice thereare a number of constraints on how a NFS server can form filehandles,based on preserving as many Unix semantics as possible
Walk the Talk
When we fall in love with arguing with people, it is a good feeling that will lead to a darn bad effect. Dale Carnegie claimed that we can't win an argument. We can't because if we lose it, we lose it; and if we win it, we lose it. Why? As often happens, the moment we triumph over the other man and shoot his argument full of holes in an apparently landslide victory, we feel good. But that particular person gets hurt and resents our

Using iptables to get around the policy based routing limitation
A while back I discovered a limitation in Linux's policy basedrouting, where you couldn't use the straightforward means to flexibly route outgoing traffic ona dual identity machine over differentinterfaces (for example, to force all SSH traffic to flow over one link,regardless of the destination). At the time I wrote:
To fix this situation up, you need to change the source IP address ofthe packets to fix them up. Unfortunately the only way I know of doingthis is to use source-
The basic implementation of relatively high-availability NFS
There's a lot of complicated approaches for high availability servicesin general. Fortunately, NFS's statelessness makes it easy to do arelatively simple, low-rent version of this.
First, make your fileserver names point to virtual IP addresses. Embodythese virtual IPs on the physical machines of your choice that have someform of shared storage. To fail over a (virtual) fileserver, take downthe IP address on the original machine, unshare and unmount everything,mount and share it on the new machine
