http://dev.mysql.com/doc/refman/5.0/en/server-parameters.html
http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html
On mac, copy macport mysql config file my.cnf to right location

cp /opt/local/share/mysql5/mysql/my-large.cnf /opt/local/etc/mysql5/my.cnf

and add following changes

innodb_buffer_pool_size = 256M
innodb_additional_mem_pool_size = 20M
# Set .._log_file_size to 25 % of buffer pool size
innodb_log_file_size = 64M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 0
#innodb_lock_wait_timeout = 50
innodb_doublewrite=0
innodb_support_xa=0

in /opt/local/var/db/mysql5, delete ib_logfile0 & ib_logfile1, since we changed log file size to 64M.

sudo /opt/local/share/mysql5/mysql/mysql.server start
sudo /opt/local/share/mysql5/mysql/mysql.server stop

Key bindings

Annoying part of mac keyboard is that it's missing whole bunch of keys, namely "home", "end", "Page Up", "Page Down", etc. According to apple's support page. You just have to push combination of buttons to accomplish that.

Home: Cmd-<
End: Cmd->
Page Up: Fn-^, in Terminal, Shift-Fn-^
Page Down: Fn-v, in Terminal, Shift-Fn-v

Terminal

Home: Shift-Fn-<
End: Shift-Fn->
Page Up: Shift-Fn-^
Page Down: Shift-Fn-v
Switch tab: Shift-Cmd-<, Shift-Cmd->

Ruby

Do not attempt to install Ruby 1.8.6 from macport. Even if you did, as some dude did, you won't be able to install gems afterwards, which requires ruby 1.8.7

Mysql

sudo port install mysql5 +server
sudo -u mysql mysql_install_db5
sudo launchctl load -w /Library/LaunchDaemons/org.macports.mysql5.plist

When install mysql ruby gems, use this

sudo gem install mysql -- --with-mysql-include=/opt/local/include/mysql5 --with-mysql-lib=/opt/local/lib/mysql5 --with-mysql-config=/opt/local/lib/mysql5/bin/mysql_config

Gnome-Terminal

sudo port install gnome-terminal
sudo launchctl load -w /Library/LaunchDaemons/org.macports.dbus.plist
launchctl load /Library/LaunchAgents/org.freedesktop.dbus-session.plist

wired article about window history.

At the public unveiling of Microsoft Windows, Bill Gates predicted it would be running on 90 percent of all IBM-compatible computers by the end of 1984. He was off by 90 percent.

Amazing window is 24 years old.

Isn't necessarily
The way you see it
Or the way it is
Or ought to be
What's more important
Is that we're all
Looking for it
And a way to see it.

gmail awesomeness

Mon, 22 Sep 2008 03:26:01 -0000

Gmail surprise me all the time, in a good way. I mean they have all these hidden features that you never known until you stumbled upon.

Today while i was replying a message, of which sender CCed another person. Initially I just clicked reply, and start writing the response, then halfway, i realized my response needs CCed person's attention also. So I copied my text, and then click "reply all", ready to paste. Out of my surprise, it show's new reply area with my halfway done response text already. How nice!

what's better than Segway?

Sun, 03 Aug 2008 01:14:24 -0000

In wired story, Toyota announced Winglet, similar to Segway, but only slower, 3.7mph, compared to Segway's 12.5 mph. and that handle stick up between the knees just looks wierd.

What's better than Segway, and Winglet? a stool you can sit on and moved like a segway, so you just need to tilt your ass to maneuver.

Install gentoo on thinkpad T61

Thu, 12 Jun 2008 05:12:50 -0000

Backup

use gparted-clonezilla to backup existing hard drive. It took about 20 minutes to backup the 6.3GB recovery partition, and another 20 minutes to backup 18GB vista partition.

Do not try to shrink vista partition in gparted, it doesn't work. won't boot. Shrink volume in vista instead.

For the longest time, I couldn't get the nvidia 140m card to work, and can only use default nv driver, then I found in the /var/log/Xorg.0.log, libwfb.so is missing. That's because the package I installed, nvidia-drivers-169.09-r1 is missing that required file. Following this direction, finally i got glxgears to run at 4183FPS.

so just unpack the older version of nvidia-drivers, and copy that file to right location.


ebuild /usr/portage/x11-drivers/nvidia-drivers/nvidia-drivers-100.14.11.ebuild unpack
cp /var/tmp/portage/x11-drivers/nvidia-drivers-100.14.11/work/NVIDIA-Linux-x86_64-100.14.11-pkg2/usr/X11R6/lib/modules/libnvidia-wfb.so.100.14.11 /usr/lib/xorg/modules/libwfb.so

Chinese Input

emerge scim # with gtk and qt3 flag

# whem scim finish emerging, it has some additional instructions.
 * 
 * To use SCIM with both GTK2 and XIM, you should use the following
 * in your user startup scripts such as .gnomerc or .xinitrc:
 * 
 * LANG='your_language' scim -d
 * export XMODIFIERS=@im=SCIM
 * export GTK_IM_MODULE="scim"
 * export QT_IM_MODULE="scim"
 * 
 * where 'your_language' can be zh_CN, zh_TW, ja_JP.eucJP or any other
 * UTF-8 locale such as en_US.UTF-8 or ja_JP.UTF-8
 * 
 * If you prefer KDE/Qt interface, try emerge app-i18n/skim.
 * 
 * To use Chinese input methods:
 * 	# emerge app-i18n/scim-tables app-i18n/scim-pinyin
 * To use Korean input methods:
 * 	# emerge app-i18n/scim-hangul
 * To use Japanese input methods:
 * 	# emerge app-i18n/scim-anthy
 * To use various input methods (more than 30 languages):
 * 	# emerge app-i18n/scim-m17n

vim ~/.xinitrc

emerge app-i18n/scim-tables app-i18n/scim-pinyin

ctrl-alt-backspace to exit X window, then restart x, then it should work.

Think finger

yes it works.
Follow the guide on Thinkwiki.

But to enable it, kernel has to has "CONFIG_INPUT_UINPUT=y", which you can find in
