upgrade to Ubuntu 10.10

There is a lot of time so I upgraded my Ubuntu to 10.10 even though it didn’t come to last release.

The biggest change is now it has a new theme: Ambiance-maverick-beta. Looks nice. Some called it “Light theme”.

And the nvidia driver looks not work with new kernel. You have edit /etc/X11/x.conf to change “nvidia” to “nv”, then you can login into X window, otherwise you will get a “no screen found” or “can’t load module nvidia” exception.

Freetype has been upgraded to version 2.4. This version turn on “Turetype bytecode” by default since this patent has expired. But I didn’t find big changes at font rendering of this version.

Ubuntu 8.04 使用感受

前些天试了下Ubuntu 8.04，有些感触。
首先，安装。我用的是硬盘安装的方式，可以参考这里。主要是在ubuntu.com找到对应的内核文件。最后MBR要装在linux的主分区上。由于vista sp1采用了新的启动方式，没有了boot.ini文件，要多重启动，需要额外的程序：EasyBCD，这个小工具可以重写MBR来引导多个OS，使用起来还是很方便的。

启动后，主题上，ubuntu变化不大，还是老样子。接上我的ipod，系统可以自动认出，可以关联到相应的程序，运行，提示缺少mp3 plug，然后自动安装，这样就可以播放MP3了，而且mp3 tag中的中文可以正常的显示，这在我的系统的语言是en的前提下，较之以前，是一个很大的进步了。

对于字体，现在相对于以前，有所改进。但是跟vista下的cleartype相比，差距还是蛮明显的。

系统自带Firefox 3.0 beta，所有功能跟vista下的一致。我常用的插件也是可以无碍的使用，可以看出firefox大大的提高了linux的接受程度。和java一样，一个容器就是一个平台，催生了一系列的相关软件。

Cygwin tips

1.if the os is windows, the file type will be dos by default. So if you new a shell script, then run it in cygwin, the error like “who/r command not found” will happen. The solution is changing the file type to unix. A approch is using vi. In vi, use “:set ff?” to inquiry file type. Then use “:set fileformat=unix” or “:set ff=unix”.

2.In my machine, cygwin.bat is:bash –login -i. This will let shell be a login shell. But only an interactive shell that is not a login shell will read and execute ~/.bashrc. If we want our personal bash, we should create a .profile file in home directory instead of of .bashrc. One example is:

alias h=”history”
alias hg=”h|grep”

#alias ls=’ls –color=auto’
alias la=’ls -A’
alias lf=’ls -F’
alias ll=’ls -l’

3.use wget with proxy. create a .wgetrc in home directory.

http_proxy = proxy.com:81
no_proxy = localhost

This will make wget to fetch data with proxy by default and you didn’t need to swith to proxy model by ” -Y on”.
