My Little Nerdy: Why do I use Linux?

Sun, 20 May 2012 15:35:29 +0800

I use Linux to make a statement.

I make a statement to appreciate the beauty of open-source software. I make a statement about my love of lifelong learning. I make a statement about frugality. I make more than just a statement. I make an invitation.

Open-source software makes the world go…

Install RPM Packages on Ubuntu

Wed, 16 May 2012 15:12:00 +0800

In Ubuntu/Linux Mint you can  install softwares from Software Centers or via PPA/Synaptic . 
If any software is not available in deb/software center/ppa and it’s only available in rpm,
 than you can  convert that rpm file to deb package with one command using terminal.



First install packages that will convert rpm packages to Debian

$ sudo apt-get install alien dpkg-dev debhelper build-essential

Now convert package from RPM format to Deb format, use the following command. 
Change your packagename in command:

$sudo alien packagename.rpm

To install the deb package

$sudo dpkg -i packagename.deb

linux 中重啓 ibus 輸入法框架，只需要一行命令：

$ ibus-daemon -d -x -r

可以縮寫成：

暴力版的，不推薦使用：

$ killall ibus-daemon && ibus-daemon -d

ubuntu/debian 修改默认shell

Fri, 11 May 2012 09:03:00 +0800

ubuntu 从 6.10 Edgy 开始，将/bin/sh链接到了/bin/dash而不是传统的/bin/bash

dash是不同于bash的shell，它的速度更快，但功能要比bash少很多，语法严格遵守POSIX标准。dash更适合执行脚本，而不是交互操作。

（dash和bash的区别可以看这一篇博客：http://www.igigo.net/page/2）

但是很多脚本都不是完全兼容POSIX标准的，而且执行某些操作（例如安装配置OpenVZ）会需要将默认的shell由dash改成bash。

方法一：

$ sudo ln -sf /bin/bash /bin/sh

方法二：

$ sudo dpkg-reconfigure dash 然后选NO

将dash恢复成默认shell，同样执行这个命令，然后选YES

https://www.accessnow.org/:

Access is a global movement premised on the belief that political participation and the realization of human rights in the 21st century is increasingly dependent on access to the internet and other forms of technology. Founded in the wake of the 2009 Iranian post-election crackdown, Access teams with digital activists and civil society groups internationally to build their technical capacity and to help them advocate globally for their digital rights. Access provides thought leadership and practical policy recommendations in the broader field of internet freedom, and based on that expertise mobilizes its global movement of citizens to campaign for an open internet accessible to all.

vim 大小寫轉換

Thu, 10 May 2012 10:32:00 +0800

大小寫轉換：gu/gU

很形象：gu轉小寫，gU轉大寫

例如，全文轉小寫只需要三個步驟：gg gu G

三個步驟的含義是：

gg => 光標移動到第一行

gu => 轉小寫的命令，gu需要指定范圍

G => 到文件結束

FreeBSD 安裝 sudo

Thu, 10 May 2012 10:24:00 +0800

# cd /usr/ports/security/sudo

# make install clean

# visudo（用visudo命令，不要直接編輯/usr/local/etc/sudoers這個文件）

%wheel ALL=(ALL) ALL （允許wheel組的用戶使用sudo）

或 %wheel ALL=(ALL) NOPASSWD: ALL（允許wheel組的用戶使用sudo而不需要輸入密碼）

或 tux ALL=(ALL) NOPASSWD:ALL（允許用戶tux使用sudo且不需要輸入密碼）

保存并退出。

FreeBSD 安装 VIM

cd /usr/ports/editors/vim

Red Hat 和 ubuntu 服务操作对比

Wed, 09 May 2012 14:26:00 +0800

启动服务：service httpd start => /etc/init.d/apache start

停止服务：service httpd stop => /etc/init.d/apache stop

让服务随系统启动自动运行：chkconfig httpd on => update-rc.d apache defaults

取消服务随系统启动自动运行：chkconfig httpd off => update-rc.d apache purge(有点问题，请查看man手册)

Linux安装完成之后要做的事

Wed, 09 May 2012 14:16:00 +0800

1. 安装vim，修改.vimrc

2. 更新系统，重启，安装驱动程序，再重启

3. 安装字体，中文字体DejaVuSansYuanTi。地址：http://forum.ubuntu.org.cn/viewtopic.php?f=8&t=110509 && http://code.google.com/p/qinsdisk/downloads/list

4. （ubuntu）安装版权受限软体包。

5. ubuntu官方源速度不错，ping了一下显示师sohu的镜像，喜欢163源的朋友可以换成163的。方法很简单：在Ubuntu Software Center的菜单里找到Software Sources……以前在系统设置里有的，12.04之后需要在软体中心里找。

Fedora和CentOS默认的源速度都不理想，参考http://mirrors.163.com的帮助，设置很简单，不赘述。

6. 源设置好之后安装常用的软件：

命令行工具：nmap, whois, hping, fping, iftop, nikto, powertop, vmstat…

图形工具：GIMP,PAC Manager(http://sourceforge.net/projects/pacmanager/)

下载工具：aMule

游戏：2D游戏引擎(https://love2d.org/)，超级玛丽(http://stabyourself.net/mari0/)
