蘇格拉底名言︰「智慧意味著自知無知。」除了無知，還有什麼能促使我們進行探索？
傑斐遜
（Thomas Jefferson）︰無知和自由兼具者，過去沒有，將來也不可能有
If a Nation expects to be ignorant and free in a state of civilization, it expects what never was and never will be... if we are to guard against ignorance and remain free, it is the responsibility of every American to be informed."

linux note
Open Office is pretty slow and painful to use out of the box. This simple step by step procedure speeds up the software, making it much more pleasant to use.
Open OOo (I use writer for this process). Select Tools -> Options. Select Memory.
Number Of Steps: 20
Use for OpenOffice.org: 128
Memory Per Object: 20
Number Of Objects: 20
Enable Quickstarter: Checked
Select Java.
Use a JRE: Checked (Alternately, Uncheck if you do not have Sun Java installed)
Select the radio button of the appropriate Java Engine if needed.
Click OK
Close OOo

with 11.2: Found out that ipv6 is no longer a module, it is in the
kernel, so you can administratively disable with a kernel option in
grub's menu.lst of ipv6.disable=1 but individual applications can
still send out v4 and v6 queries. In my case yast2 -> software ->
online update still sends out both, until I find out how to disable.

ALSA Driver
I got a simple solution for this compile problem.
Just open the ”./include/adriver.h” file in a text editor, go to line 100 and do one of the following :
Comment out the typedef : //typedef unsigned int fmode_t;
Change the kernel number : #if LINUX_VERSION_CODE < KERNEL_VERSION(2, 6, 27)
(I've got the 2.6.27-xxxx so this effectively cancels the typedef without breaking compat with older kernels)
No if only I could get this laptop to make some noise … :(
VMWARE E1000 NIC QUICK HOW TO:
The steps are for VMWare Server 1.0, but may be similar
for other versions of VMWare. Use at your own risk.
No warranty is expressed or implied.
Some users have reported problems with the Lance (default)
and VMXNet network card drivers with FreeBSD 6.x. If these
occur, it is recommended to use the E1000 driver in their place.
1. In /etc/rc.conf, change ifconfig_lnc0 to ifconfig_em0
2. Make the same change in /usr/local/etc/conftemplates/rc.conf
3. shutdown -h now
4. (On host) Edit the/FreeBSD.vmx
5. Add a line:
ethernet0.virtualDev = "e1000"
Just below:
ethernet0.present = "TRUE"
6. Boot the VM
ffmpeg -f x11grab -s wxga -r 25 -i :0.0 -sameq /tmp/out.mpg

生生死死，昨日今日明日很難分！
歌名：Hallejujah 原唱：Leonard Cohen
John Cale - Hallelujah Lyrics
I've heard there was a secret chord
That David played and it pleased the Lord
But you don't really care for music, do you?
It goes like this
The fourth, the fifth
The minor fall, the major lift
The baffled king composing Hallelujah
Hallelujah
Your faith was strong, but you needed proof
You saw her bathing on the roof
Her beauty and the moonlight overthrew you
She tied you
To a kitchen chair
She broke your throne, she cut your hair
And from your lips she drew the Hallelujah
Hallelujah
Baby I've been here before, I know this room
I've walked this floor
I used to live alone before I knew you
I've seen your flag on the Marble Arch
Love is not a victory march
It's a cold and it's a broken Hallelujah
Hallelujah
There was a time you let me know
What's really going on below
But now you never show it to me, do you?
I remember when I moved in you
And the holy dove was moving too
And every breath we drew was Hallelujah
Hallelujah
Maybe there's a God above, all I ever learned from love
Was how to shoot at someone who out drew you
And it's not a cry you can hear at night
It's not somebody who's seen the light
It's a cold and it's a broken Hallelujah
Hallelujah
Hallelujah
生生死死，昨日今日明日很難分！
