The smart-split function split the emacs frame into a maximum number of 80-column windows. A very portable solution.

First, determine what controller you have:

lspci | grep CardBus

If you see something like this:

06:07.0 CardBus bridge: Texas Instruments PCIxx21/x515 Cardbus Controller

congratulations, you have the same controller as I do, and the following procedure might work for you.

Create the file /etc/init.d/tifm with the following content:

#!/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
NAME=tifm
DESC="Texas Instrument Integrated Flash media controller"

# use lsb-base
. /lib/lsb/init-functions

retval=0
case "$1" in
    start)
        sync
        modprobe tifm_core
        modprobe tifm_7xx1
        modprobe tifm_sd
        log_end_msg $retval;
    ;;
    stop)
        modprobe -r tifm_sd
        modprobe -r tifm_7xx1
        modprobe -r tifm_core
        log_end_msg $retval
    ;;
    *)
        N=/etc/init.d/$NAME
        echo "Usage: $N {start|stop}" >&2
        retval=2
    ;;
esac

exit $retval

Make it executable and start at boot time:

sudo chmod +x /etc/init.d/tifm
sudo update-rc.d tifm defaults

To try it right away:

sudo /etc/init.d/tifm start

Plug in a card and it should be auto-mounted.

今天装了compiz (hardware-accelerated desktop)。没做什么特别的设置就好了，对于一个Linux下还处于alpha状态的软件来说，有点让人意外。效果的确很impressive，感觉比Mac OS X还眩一些。Linux向一个能被一般用户接受的桌面系统这个方向已经走了很远。

可惜切换workspace的动画不能截图。

# Disabled for now - the latency tends to be bad enough to make it

But by enabling it and turning of on-demand scaling, you can manually decrease CPU frequency to reduce heat and power-consumption when your laptop is lightly loaded. There’s how:

You need powernowd which is included in a standard Ubuntu installation. To make sure:

sudo apt-get install powernowd

Override the default configuration to enable p4-clockmod:

sudo su
echo "FREQDRIVER=p4-clockmod" >/etc/default/powernowd

To let your non-root account change CPU frequency, set the setuid bit of cpufreq-selector, so that it runs as root:

sudo chmod +s /usr/bin/cpufreq-selector

Now add the CPU frequency scaling monitor to your GNOME panel, you should be able to change the frequency by click on the icon.

用 google 找了个测试字体的 Java 程序试了一下，是一个叫 Rekha 的字体作怪。只要把 ttf-gujarati-fonts 卸掉就可以了：

$ apt-get remove ttf-gujarati-fonts

不过这样也会把 ubuntu-desktop / kubuntu-desktop / xubuntu-desktop 等顶层的包卸掉，不过那些包本身没什么内容，应该不要紧。

另外发现了一个很好用的工具 apt-file ，可以查找某个文件所属的安装包：

$ apt-get install apt-file
$ apt-file update
$ apt-file search Rekha.ttf
ttf-gujarati-fonts: usr/share/fonts/truetype/ttf-gujarati-fonts/Rekha.ttf

Email today has many annoyances. Even though we now seem to have a grip on the spam problem, many users are suffering from email overload: There are just too many emails flooding the inbox. Many are drowning in heaps of emails that aren’t even important – it’s just a colleague at work Cc-ing everyone evenly remotely connected to his project.

Update一下：今天看到 priv 改进的版本 ，觉得改动和我现在的相似并且更加好用，所以我也就没有必要再发布一个版本了。

比较适合不得不用Windows又觉得微软的UI很dull的人。
