假期越来越无聊了，喜欢的人回家了，天天想。
回到家里呆了一个星期，应该还不到，就又回到了学校。满校准备考研的人，我都想加入进去了。
觉得没这个必要，再接着学习的话我就真的长不大了。

Patched libraries are built against freetype 2.3.x (not currently in feisty) and include David Turner's subpixel rendering patches.

deb http://www.telemail.fi/mlind/ubuntu feisty fonts
deb-src http://www.telemail.fi/mlind/ubuntu feisty fonts

• To install the packages
  
  Code:

  sudo aptitude update
  sudo aptitude install libfreetype6 libcairo2 libxft2

• After the install, you may want reconfigure font settings. I'm currently using Feisty defaults (Native, Always, No bitmapped fonts) myself.
  
  Code:

  sudo dpkg-reconfigure fontconfig-config
  sudo dpkg-reconfigure fontconfig

• If you get errors about missing gpg key
  
  Code:

  wget http://www.telemail.fi/mlind/ubuntu/937215FF.gpg -O- | sudo apt-key add -

  (or alternatively)
  
  Code:

  gpg --keyserver subkeys.pgp.net --recv-keys 937215FF
  gpg --export --armor 937215FF | sudo apt-key add -

• GPG key to RAOF's repository (amd64 packages)
  
  Code:

  wget http://ubuntu.moshen.de/2F306651.gpg -O- | sudo apt-key add -

• If you later decide to go back to Ubuntu packages, you must downgrade all three installed packages
• You'll probably need to restart X-server after installing the packages to see the changes apply

Setting up a computer to share its internet connection should be easy.After all, you’ve successfully networked your computers together and even shared files with all your home computers, so why not the Internet? Well if you have a small home network of computers all connected and have tried to open up a browser, you’ve probably found out that things aren’t quite as straight forward as connecting one machine with an Ethernet cable to the computer that has the DSL/cable modem.

The secret is that everything comes down to having a gateway.

A gateway is a computer or device than can route data between different networks. Put it this way, if your computers are on one network and every other computer connected to the Internet is on a different one, to pass information across network boundaries you need a device which is connected to both networks and equipped to decide whether information from one network should go out to the other network, and vice versa.

So, without a gateway there is no way for the other computers in your network to receive or pass information to the other networks, and consequently, they have no Internet access.

The computer in your small network which is directly connected to the cable or DSL modem is provided with a default gateway by the Internet service provider. That allows the computer to connect to the interenet, but unfortunately for us that gateway is not part of your home network - rather it is a separate network formed between the computer connected to the cable/DSL modem and the ISP itself.

In order to enable Internet access on the rest of your small home network, the computer or device that connects with your ISP must become a gateway for the computers in your local home network. Once this has been configured, it will enable all of the other home network computers to access the Internet by sending and receiving information through that gateway.

The easiest way of acquiring a gateway for your home network is to buy a cable/DSL router. Given how cheap they currently are (about a quarter of the price they commanded when they first appeared in the marketplace), there really isn’t much of an excuse not to buy one.

The major advantages of having a hardware router doing your internet sharing include minimal configuration, since they are set up to act as a gateway by default (it’s pretty much all they do), increased reliability (they are not a PC… PCs crash.), and security, since most of these devices incorporate a firewall. Highly recommended!

You’ll also need

a working dial-up Internet account with an Internet Service Provider (ISP) or

a working broadband (cable, DSL, satellite, etc.) Internet connection.

Share your Internet connection using the following Procedure

Note: Type all the following commands in a root terminal

Start by configuring the network card that interfaces to the other computers on you network

# ifconfig ethX ip

where ethX is the network card and ip is your desired server ip address (Usually 192.168.0.1 is used)

Then configure the NAT as follows

# iptables -t nat -A POSTROUTING -o ethX -j MASQUERADE

where ethX is the network card that the Internet is coming from

# echo 1 > /proc/sys/net/ipv4/ip_forward

Install dnsmasq and ipmasq using the following command

# apt-get install dnsmasq ipmasq

Restart dnsmasq using the following command

# /etc/init.d/dnsmasq restart

Reconfigure ipmasq to start after networking has been started

# dpkg-reconfigure ipmasq

Start by configuring the network card that interfaces to the other computers on you network

# ifconfig ethX ip

where ethX is the network card and ip is your desired server ip address (Usually 192.168.0.1 is used)

Then configure the NAT as follows

# iptables -t nat -A POSTROUTING -o ethX -j MASQUERADE

where ethX is the network card that the Internet is coming from

# echo 1 > /proc/sys/net/ipv4/ip_forward

Add the line “net.ipv4.ip_forward = 1″ to /etc/sysctl.conf

# gedit /etc/sysctl.conf

Reboot your system is optional.

说是xmame-x11好像和ATI的fglrx有点问题, 换成xmame-sdl变OK了.不过这个方法我没试过.
又发现一个,管用:
If anyones interested I found the problem with the black screen on Mame - at least, this worked on my machine using KXMame. I believe the problem has to do with the DGA video mode when running an ATI graphics card with the fglrx drivers, which is buggy and/or broken.

I have been tweaking around with my xorg.conf file and made the following changes:

Under Section "Module"
SubSection "extmod"
Option "omit xfree86-dga" #Don't initialize the DGA extension
EndSubSection

And commented out the extmod module with a #, like so
# Load "extmod"

Restarted X with a ctrl+alt+backspace and voila! I no longer get the black screen when launching kxmame/gxmame. It took quite a lot of investigation, I hope someone finds this useful.

克里希那穆提说：“到底有没有成就这样东西？还是它只是人类追求的一个观念而已？因为你即使达到了目标，永远都还有一个更远的目标在前面等待你去完成。只要你追求任何方面的成就，你就不可避免地会陷入奋斗和冲突之中，不是吗？”

人生如果不去追求任何形式的成就是不是就没有动力了呢？这些世俗的所谓成就一方面是肤浅的，另一方面，它也是没有止境的。如果一个人此生的目的就是追求那些用各种各样的世俗标准来衡量的成就，譬如名望、金钱、地位，那他就永远不能停歇，永远没有时间享受此生的快乐。

如果我们的生命不应当用来追求成就，那么应当用来做什么呢？人怎样才能获得快乐的人生呢？克里希那穆提为我们提供的人生方案就是：并不与他人竞争；并不追求世俗的成就；只是去做自己真正想做的事情。只有这样，我们才能成为一个自由的人，拥有快乐的人生。

Customizing Firefox

To Access FireFox's configuration file type about:config into the url

Now let's get Firefox to run faster:
Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.
Set "network.http.pipelining" to "true"
Set "network.http.proxy.pipelining" to "true"
Set "network.http.pipelining.maxrequests" to 15.
Right-click anywhereinside the firefox winodw and select New-> Integer.
Name it "nglayout.initialpaint.delay" and set its value to "0″.

Firefox downloads webpages from links it thinks you may click. This may make the "experience" seem faster but really it just bogs down Firefox and you PC.
Set "network.prefetch-next" to false

Remove some annoying Firefox features:
Turn off chrome tooltips, this causes little pop up winodws to tell you what your mouse is hovering over. If you been using Firefox for as long or longer than I have (before 1.0) you really don't need to be told what the back button does. It also hinders dragging a bookmark into the bookmark toolbar folder, the tool tip gets in the way and prevents the drop from working.
Set "browser.chrome.toolbar_tip" to false

Customize backspace button, the Ubuntu default is set to scroll up when hit. I prefer it to work like it did in Windows and go back in my page history.
Set "browser.backspace_action" to either 0 or 1
0 - Pressing backspace button will go back a page in the session history
1 - Pressing backspace button will scroll up a page in the current document and
[Shift]+[Backspace] will scroll down.

Remove URL GO button. No one over the age of 4 and under the ago of 50 uses it.
Set " browser.urlbar.hideGoButton" to true

使用方法：
mid3iconv -e gbk *.mp3

如果想转换当前目录下的所有 mp3 (包括子目录)：
find . -iname "*.mp3" -execdir mid3iconv -e gbk {} \;

* 相信现在大陆绝大多数能找到的 mp3 标签都是以 GBK/GB18030 编码，使用 -e gbk 来处理就够了，当然你也可以使用 -e gb18030 来处理。
* -e gbk 参数是代表把 GBK 编码的标签转换为 Unicode 编码，本身是 Unicode 编码的就不转换。如果需要转换其他编码的文件可以自行修改，如改为 Big5。
* 经测试，转换后为 2.4 版的 ID3v2，编码格式为 uft-16
* 不过它会同时用 Unicode 编码填满 D3v1, ID3v2, APEv2 标签，但是 ID3v1 又不支持中文的 Unicode 编码，所以转换后的 ID3v1 标签全是问号。所以最好加上 –remove-v1 参数，转换后删除 ID3v1 标签。
