我的联想U150的本本的BCM4315网卡一直没有得到BT4和BT3的完美支持，就连Ubuntu 9.10装好后也需要自己再装Restricted Driver。这个驱动装好后好像不能被aircrack系列支持。我认为只要把4315驱动搞定了，就能在任何Linux系统下应用aircrack。那么第一步就是把b43驱动驱动起来。
寻找了很久以后找到了这个帖子：http://ubuntuforums.org/showthread.php?t=1266620
使用2.6.32.12的kernel加上b43的驱动就可以完全搞定它。
1、32位系统的内核：
http://mirrors.kernel.org/ubuntu/pool/main/l/linux/linux-image-2.6.32-12-generic_2.6.32-12.17_i386.deb
http://mirrors.kernel.org/ubuntu/pool/main/l/linux/linux-headers-2.6.32-12-generic_2.6.32-12.17_i386.deb
http://mirrors.kernel.org/ubuntu/pool/main/l/linux/linux-headers-2.6.32-12_2.6.32-12.17_all.deb
2、安装内核：
sudo dpkg -i linux*2.6.*.deb
3、下载compat-wireless驱动（http://linuxwireless.org/download/compat-wireless-2.6/），照着它的说明，我用最新的编辑无法成功，用compat-wireless-2010-01-26.tar.bz2即可。
4、编译：
make
sudo make install
5、卸载老的驱动
sudo make unload
6、刷新驱动
sudo depmod
sudo depmod -a
7、打开PIO模式：
echo "options b43 pio=1" | sudo tee -a "/etc/modprobe.d/b43-thingy.conf"
8、屏蔽STA驱动：
echo "blacklist wl" | sudo tee "/etc/modprobe.d/wedontneednonossdrivers.conf"
9、启动时打开B43驱动：
echo "b43" | sudo tee -a "/etc/modules"
10、打开/etc/rc.local， 在exit(0)之前加入
modprobe -r b43
sleep 3
modprobe b43
然后就可以用aircrack的工具进行破解了。
spoonwap在ubuntu的sudo环境下回提示表达式不正确，解决方法是
sudo ln -sf bash /bin/sh
然后享受吧，我用了1分多的时间把自己的无线网络破解了，隔壁的网络没有活动的客户端破解相对繁琐，改日再研究。

由于6.5版本的vmware的vmtools的默认安装存在一些问题，貌似是和新的kernel不怎么兼容，所以无法实现屏幕自动缩放、拖拽等功能。在国外网站上搜索了一下，经过实践，发现这样可以解决问题：
sudo aptitude update
sudo aptitude install build-essential linux-headers-$(uname -r)
cd /cdrom
cp -a /media/cdrom/VMwareTools* /tmp/
cd /tmp/
tar -vxzf VMwareTools*.gz
cd vmware-tools-distrib/
sudo ./vmware-install.pl

do

sudo umount "$I" && zenity --info --text "Successfully unmounted /media/$I/" && sudo rmdir "/media/$I/"
done
done
exit 0
sudo chmod 755 ~/.gnome2/nautilus-scripts/*_iso
然后重启x: ctrl+alt+backspace

I have experienced a bridged networking issue in VirutalBox 3.0.4 with Vista as host and Ubuntu 8.10 as guest.
My networking is installed as following:
A TP-LINK WR340G router configured with DHCP on; Vista Host system linked to this router and can get IP automatically; Ubuntu 8.04 refreshly installed in VirtulBox 3.0.4.
After I installed VirtualBox Addition, guest networking seemed hard to get IP from router. Somestimes it could get a IP. In most time, the networking configuration said that "the link was disconnected".
I searched and someone said that change guest's network card to "Intel PRO/1000 MT Desktop" might solve the problem. I tried it and successed.
If you have this problem, try to change your guest's card type.

Have you ever tried downloading things from Internet using mobile phone? I guess you probably have experienced fetching some pictures and text, or something bigger like short movies or musics.
On Friday morning, when I was listening to ERC conference which was held by Sun at Shangri-La in Chengdu, I felt a little boring when a professor talking about eduction in Russian because I didn't quite catch him. Russian English and Indian English is a little hard to understand.
I have nothing to do, so I take out my phone to play. I searched WiFi singal and found hotspot of Shangri-La. April 23th was my birthday and also the release of Ubuntu 9.04. I found the download link and started to download using UCWEB which can do multi-threaded downloading. The download speed grew up to and keep stable at almost 200kb/s. At this speed, one times faster than I had in my dormitory, I could get Ubuntu cdimage in only one hour.
How much enegery it cost? I opened the Nokia Engery Profiler and it showed me the real-time current and power consumption of the phone. In average, the phone ate up about 400mA or equally 1.3Watt. So my battery could keep up at least 3 hours downloading. That is to say, I could download 2GB of data from the air before my battery run out. But I'm a little afriad of the battery, it was getting a little warmer.
Downloading by a phone is quite "green". Compare to a normal computer, it uses 0.1KWh every hour and my phone only uses 1% of the energy. So it could be the most energy-saving downloading method I ever seen. I'm wondering if there is some Bittorrent or Emule software I can use on the phone, so I could do my best to saving the earth! Besides, without a WiFi, I could do nothing.
