十二星座撰（转摘）
31/12/2007 20:32白羊座
妈妈经常叮嘱羊羊：“穿裙子时不可以荡秋千；不然，会被小男生看到里面的小内裤哦！”
有一天，羊羊高兴地对妈妈说：“今天我和小明比赛荡秋千，我赢了！”
妈妈生气地说：“不是告诉过你吗？穿裙子时不要荡秋千！”
羊羊骄傲地说：“可是我好聪明哦！我把里面的小内裤脱掉了，这样他就看不到我的小内裤了！”
(勇敢直率、敢做敢为的白羊）
金牛座
卖瓜小贩：“快来吃西瓜，不甜不要钱！”
饥渴的牛牛：“哇！太好了，老板，来个不甜的！”
(持家、想出轨又顾全自己的金牛）
双子座
妈妈叫双双起床：“快点起来！公鸡都叫好几遍了！”
双双说：“公鸡叫和我有什么关系？我又不是母鸡！”
(自我意识强烈、自行思维的双子）
巨蟹座
公车上，蟹蟹说：“今晚我要和妈妈睡！”
妈妈问道：“你将来娶了媳妇也和妈妈睡阿？”
蟹蟹不假思索：“嗯！”
妈妈又问：“那你媳妇怎么办？”
蟹蟹想了半天，说：“好办，让她跟爸爸睡！”
妈妈：“！＠＃＄％＾＆＊（……—”
再看爸爸，已经热泪盈眶啦！
(恋母情结、依恋的巨蟹）
狮子座
狮狮去参加奶奶的寿宴。到了吃寿包的时候，狮狮问：“我们为什么要吃这种像屁股的寿包？”
众人听了脸色大变。
接著狮狮拨开寿包，看看里面的豆沙，说：“奶奶，快看！里面还有大便！”
众人晕的晕，吐的吐。
(以自我感受、不怕旁人眼光的骄傲的狮子）
处女座
处处对肚脐很好奇，就问爸爸。
爸爸把脐带连著胎儿与母体的道理简单地讲了一下，说：
“婴儿离开母体之后，医生把脐带减断，并打了一结，後来就成了肚脐。”
处处：“那医生为什么不打个蝴蝶结？”
好奇心强又追求完美的处女）
天秤座
父亲对天天说：“今天不要上学了，昨晚．．．你妈给你生了两个弟弟。你给老师说一下就行了。”
天天却回答：“爸爸，我只说生了一个；另一个，我想留著下星期不想上时再说！”
(聪明、权衡利弊的天平）
天蝎座
蝎蝎刚睡著，就叫蚊子叮了一口。
他起来赶蚊子，却怎么也赶不出去。
没法，便指著蚊子说：“好吧，你不出去我出去！”边说边出了房间
把门使劲关严得意地说：“哼！我今晚不进屋，非把你饿死不可！”
(搞不懂、不按常理出牌的天蝎）
射手座
射射：“爸爸，为什么你有那么多白头发？”
爸爸：“因为你不乖，所以爸爸有好多白头发阿。”
射射：……（疑惑中）
射射：“那为什么爷爷全部都是白头发？”
爸爸：！＠＃＄％＾＆＊（……
(喜欢思考的射手）
摩羯座
一天，羯羯跟妈妈上街；走在路上，突然下起雨来。
妈妈拉过羯羯的小手，说：“下雨了，快往前跑阿！”
羯羯慢条斯理地问：“那前面就不下雨喽！？”
(明白现实懒得改变的摩羯）
水瓶座
瓶瓶问妈妈：“问什么称蒋先生为『先人』？”
妈妈说：“因为‘先人’是对死去的人的称呼。”
瓶瓶说：“那去世的奶奶是不是要叫『鲜奶』？”
(天生的另类、脑筋思考永远和常人不一样的水瓶）)
双鱼座
爸爸给鱼鱼讲小时候经常挨饿的事。
听完後，鱼鱼两眼含泪，十分同情地问：
“哦，爸爸，你是因为没饭吃才来我们家的吗？”
(富含丰富同情心、不分情况对象的双鱼）

Compile FreeBSD Kernel
14:11First of all, you need to have full FreeBSD source tree to build the kernel. If you dont, download them now.
* COPY /usr/src/sys/i386/conf/GENERIC /root/sys/TAO and ln -s /root/sys/TAO /usr/src/sys/i386/conf/TAO
* vi /root/sys/TAO, comment all the device you dont need
* Change scheduler to ULE if you are using FreeBSD 7 (experimental), as mention by Kris, new ULE scheduler has better performance than tranditional 4BSD
http://www.elian.co.uk/2007/12/22/does-freebsd-7-solve-its-mysql-problem/
* Change /etc/make.conf. As V7 support core2 CPUTYPE, so
CPUTYPE?=core2
CFLAGS=-O2 -fno-strict-aliasing -pipe
For pre 7 users, see
http://gentoo-wiki.com/Safe_Cflags#Intel_Core_2_Duo.2FQuad_.2F_Xeon_51xx.2F53xx
*Go to /usr/src/sys/i386/conf directory, and run config TAO to create a compile directory. It is very helpful if you want to keep serveral version of kernel
* Go to ../compile/Tao and run make cleandepend && make depend
* and “make”, it will take very long time and depending on the speed of your machine and your configure file
* make install and reboot your machine. If the new kernel cannot be load correctly or some devices do not function, you can use load kernel.old or kernel.GENERIC to go back to old kernel or generic kernel
N.B. here is my kernel configure file
http://www.elian.co.uk/2007/12/23/taos-kernel/
* After installing new kernel, you have to rebuild your world, otherwise, many program cannot run correctly(To me, sockstat -cl cannot should TCP ports listening)
cd /usr/src
make buildworld (took about two hours)
reboot into single user mode
mergemaster -p
make installworld
mergemaster
reboot

My FreeBSD installation
13:03* Minimal installation(very simply, google it or follow the manual book on FreeBSD website). enable softupdate for non-root slice
* Install man package
* Install cvsup by pkg_add -r cvsup-without-gui (run rehash or re-login)
* Install vim “pkg_add -r vim-lite”
* Using vim instead of vi(may have security issue, careful!). ln -s /usr/local/bin/vim /bin/vi
* Copy /usr/local/share/vim71/vimrc_example.vim to /usr/local/share/vim71/vimrc (gramma hightlight)
* I prefer to use stable-supfile, so copy it to /root and change host address
* Copy /var/share/examples/cvsup/refuse to /var/db/sup. Dont download source code other language, english only.
* Update source code tree now, by cvsup stable-supfile.
* It will take some time, so sit back and have a cup of coffe ^_^
* I personally like to use portsnap to update port tree, so “portsnap fetch extract”
* Copy and edit /etc/make.conf. Change CFLAG and disable GUI by
NO_X= true
NO_GUI= true
WITHOUT_X11= yes
WITHOUT_XPM= yes
* Edit /etc/rc.conf
* To compile kernel, you can follow my another post on
http://www.elian.co.uk/2007/12/23/compile-freebsd-kernel/
* Email system:
I prefer postfix, and you can find many webpage in google on how to replace sendmail with postfix. and it is easy to do so
cd /usr/src/mail/postfix
make install
select SASL2 and TLS, if you need MySQL support, simply add MySQL
add sendmail_enable=”NONE” to /etc/rc.conf
cp /etc/default/periodic.conf /etc/periodic.conf and change following directive (Disable sendmail dail)
daily_clean_hoststat_enable="NO" daily_status_mail_rejects_enable="NO" daily_status_include_submit_mailq="NO" daily_submit_queuerun="NO"
* Config postfix by editing /usr/local/etc/postfix/main.cf
* Install other services

Does FreeBSD 7 solve its MySQL problem?
22/12/2007 19:19A very famous article by Jeremy pointed out the reason mysql database had lower performance on BSD system which is my most preferred OS (http://jeremy.zawodny.com/blog/archives/000203.html). Although, there is a work-around by using LinuxThread (http://pauillac.inria.fr/~xleroy/linuxthreads/), it cannot satisfy all the pure BSDers.
Since the annoucement of V7, many people are exciting for its new features. Especially, the improvement of scheduler, both 4BSD and ULE. But the question is does V7 really solve the MySQL problem? what is the performance of MySQL on FreeBSD 7. I read Kris’ “7.0 Preview” today, it really makes believe so.
