Spend all night play ancient art of war game and surf some photo blog, nothing interesting. I though I am going back to the office tonight, but is raining, so lazy, better go to sleep early.
Ancient art of war is a very old war simulation game, written by Murry Brother (Dave and Barry) from Evryware, release by Broderbund in 1984, yes 20 year ago. I still like it.
The fan page is here.

Try to setup my housemate's PC. I have install the Windows XP operating system (he prefer to use windows). The next thing should setup the broadband network.
I plugin a 3Com etherlink 3 network card, everything just work fine. Yesterday my housemate bought a D-Link wireless network card (model DWL-G520+), I just plug it in, though it will just plug and play like other network card, but it doesn't. I install the driver which came with the D-Link network card, is not working too.
Finally I pick up the manual and read. I am a lazy person, I should have read the manual first. I just find out from the manual, it stated "Warning! Do NOT install the Wireless card into your computer before installing the driver".
The nightmare has just begin, for the next 10 hours, I try to download every wireless driver that I can try on the d-link website, searching the FAQ for the problem, try install the driver with plug and unplug the network card, it just not working.
I though I am going to give out, until someone says something here, he read from some forum, suggest to use a US Robotic driver, since both of them using a TI chipset.
Finally it works, the USR driver working for D-Link wireless card! I have spend more than 10 hours try a broken driver from D-Link.

Many bad things happen today, four bombs exploded in London, 33 killed, many people injured. British prime minister Tony Blair confirm hit by terrorists, rush back from G8 summit.
About 26 people attend today's meetup, I gave a presentation on Postgresql, I overshoot the time. I really need someone do timing for me. Molly bring 2 gentleman--Bhaskar talk on open source database as well, finally Chin Fah talk on iSCSI.
Today I feel very tired and restless, too many bad things happen.

I use vi a lot for my software development, both unix and java program. I am not an vi expert, just enough for my normal use, but search and replace in vi is troublesome for me, I get a 2 different answer from experience vi user, it work well for me, but when I ask them why there is 2 different format, they don't give me a well explain, so I just copy down and follow...
I try to use other format, it just don't work.
Finally I read the O'Reilly's 'sed and awk' book, and figure out what is the format:
(this pattern works in sed, and ed too)
address is optional ( shown by [ ] )
g, global, all the lines
n,m, line n to line m, $ stand for last line. eg. 1,$ is same as global
filter out the pattern line by line, pattern is optional, if pattern is provided only those lines with filter pattern, will be search and replace
the 2nd [pattern] after s/ is the search pattern
if the search pattern is not provided, the pattern will follow the (1st) filter pattern, but the search pattern could be different from the filter pattern. eg. :g/hello world/hello/Hello/
the target pattern that you want.
the final [c,g]
c, confirm 1 by 1
g, global, all, (for the line only), if replace all line must specified in address. if nothing is provided, only the 1st exist pattern will be replace. eg. the there is 2 'hello world' exist in each line, only the 1st 'hello world' will change to 'Hello world', with capital 'H'.
