Firefox: 1.5 – 3.0a1 
今天听说Pidgin 2的正式版发布了，但是没有Deb包可供下载。本来打算自己根据源码包编译一个Deb包给大家，可惜水平有限，错误不断，没有成功。只能留给以后了。
但是，天底下就有这么巧的事。无聊之下，上Gnome-look逛逛，居然发现了Pidgin 2 For Feisty的Deb包！这个网站，居然还放这个东西……哈哈，废话不多说了，大家一定要想了。
注意：这个版本是For Ubuntu 7.04 Feisty Fawn i386，并且不能与Gaim共存，安装前先请删除Gaim（删除Gaim的同时，会把ubuntu-desktop和nautilus-sendto也 删除掉，这样可能会丧失右键“发送到…”功能）。
首先进入：http://rapidshare.com/files/29542172/pidgin_2.0.0-1_i386.deb
注意这不是Deb包，而是一个网站，网址具有迷惑性 。
然后点击右侧下面“Free”按钮，然后可以选择任意下载点，输入完验证码，就可以下载了。
下载完后，直接：
sudo dpkg -i pidgin_2.0.0-1_i386.deb
安装吧！
哈哈。看我的Pidgin和Avant工具条，图标都变好看了~

This guide is for tweak geeks, just like myself 
There is absolutely no need to tweak Feisty since it runs very well with the default installation. BUT there are some things that can be done to make it run just a little bit faster and smoother.
So that’s why. And since it works so great for me why not share my setup with others just like me and hopefully help you get a greater experience out of your computer and Feisty installation.
This is in no way a default set of tweaks that will give the same kind of improvements for everyone and you use them at your own risk.
For some one tweak might work better than for others. It all depends on the hardware and the way you use your system…
Some basic knowledge in Linux is a plus so that you have a basic understanding in what you are doing.
And remember, these tweaks are what I use to get the most out of my Kubuntu Feisty experience. To me it speeds up the boot process and gives me a snappier desktop and applications then the default installation of Feisty.
In general it seems that these tweaks works better on newer hardware and if you got lot’s of RAM (at least 512 MB) and SATA disks.
In my examples I use kate as my editor, if you are using gnome replace kate with gedit. Or if you are a “Uber geek” vi, emacs or whatever your choice of editor is…
And if you are not an daredevil, copy/backup the files you modify before editing them.
Ok then, enough blabbering, lets get to it…
! YOU DON’T NEED TO DOWNLOAD AND RUN THIS SCRIPT TO APPLY THE FOLLOWING !
Before downloading and running this script you need to comment out the line in /etc/apt/sources.list that starts with:
deb cdrom:[Kubuntu 7.04 _Feisty Fawn…
With a # sign at the beginning of that line
And do I need to remind you of that I run Kubuntu. So obviously some of the apps are KDE apps…
Here is my Fly Like A Butterfly setup script:
flb.script.sh
Download it and run chmod +x on the file. then run:
sudo ./flb-script.sh
From a console
It will make a copy of your original sources.list file to /etc/apt/sources.list.flb-backup.
This script enables the medibuntu and automatix repos for feisty and installs the most common media codecs needed and some applications that I use.
yakuake
rdesktop
sysv-rc-conf
preload
libxine-extracodecs
libmad0
mplayer
mplayer-fonts
libdvdcss2
w32codecs
skype
sun-java6-plugin
sun-java6-fonts
gsfonts-x11
And some other additional packages that are required by those.
I’m no script kid so it is a very simple script. It could probably use a lot of touch ups…
Disable IPv6
At least I dont need ipv6 yet so this is what I do to disable it. In the future there might be some use of ipv6 but until then I’ll keep disabling it.
sudo kate /etc/modprobe.d/aliases
And change the line:
alias net-pf-10 ipv6
to:
alias net-pf-10 off #ipv6
Now comment out all the lines that has to do with Ipv6 in your hosts file.
sudo kate /etc/hosts
This will disable IPv6 on all network interfaces. You need to reboot.
Run boot processes in parallel
This will make upstart to run the boot processes in parallel and speed up the boot process.
sudo kate /etc/init.d/rc
Find and change the line:
CONCURRENCY=none
to:
CONCURRENCY=shell
Make sure to check your spelling, one little mistype here and you won’t be able to boot!!!
This one seems to do best if you are using SATA or SCSI but even on my old computer with the old ATA it does make the KDM login screen show up a little bit faster.
There could actually be that this tweak slows down your boot if you are using old hardware…
Aliasing hostname to localhost
Right or wrong, you decide. But I picked this up in the Ubuntu forums some time ago and it does improve the startup of some apps.
sudo kate /etc/hosts
and add you hostname to the first line after localhost like this:
127.0.0.1 localhost yourhost
127.0.1.1 yourhost
Disable pango
I know that this is already taken care of in firefox but it still makes a good performance boost to thunderbird and some other apps.
sudo kate /etc/environment
and add:
MOZ_DISABLE_PANGO=”1″
Disable gettys
Thank’s to some anonymous user for the tip.
sudo kate /etc/event.d/tty3
and comment out the lines starting with start and respawn with a number sign (#).
This does not improve my performance at all but it saves a little resources so why not
Preload
It does what you think. It preloads most common used libs and application = faster startup times on your applications (this does not increase your boot speed as some might think).
sudo apt-get install preload
What about prelink?
Prelink is no longer necessary in feisty. Feisty uses a new linking mechanism called DT_GNU_HASH which speeds up the linking process without the need for continuously running prelink.
Swappiness
The default value for vm.swappiness is 60 in Ubuntu Feisty whic is a good default value but if you want to tweak the performance a little bit more you can change this value to a lower value to reduce the load of the swap. If you run the follwing command:
sysctl -q vm.swappiness
You will se that the value is set to 60. And by running:
sudo sysctl vm.swappiness=10
You will change the value from 60 to 10 which will make your system write to swap a lot less and I would recommend this to everyone that has 512 MB of memory or more. If you find that you have very little use of swap set the value to 0. This will not disable the swap but it will make your system write to the swap as little as possible and keep as much as possible in memory. This makes a huge improvement when switching between applications since they are now likely to be in physical ram instead of on the swap partition.
To set your value permanent you need to change the sysctl.conf file:
sudo kate /etc/sysctl.conf
Add the line
vm.swappiness=10
To the end of the file. This way it will be set upon boot.
I’ve found that the value of 5 works very good for my use and I have 1 GB of memory.
Grub option profile
There is a option to grub called profile which will profile your startup. What it does is that it kind of indexing all the files read during boot/startup and later on it will find and read those files quicker.
Hit the escape button when booting to get to the grub menu.
Select your default boot kernel and hit the e button.
Go down to the second line and hit the e button again.
Add profile to the end of the line and press enter.
Hit the b button to boot with your new option.
The first time it will take a little bit longer to boot because it has to build the index (or whatever they want to call it) but every boot after this will be a lot smoother.
You need to do this every time you update your kernel or have made other huge changes to your system that might affect the files needed during boot.
sysv-rc-conf
Install sysv-rc-conf and disable the services you don’t need at startup.
As an example. On my computer I don’t have bluetooth or PCMCIA so I don’t need to start it at boot time.
So simply disable what ever you don’t have or use.
sudo apt-get install sysv-rc-conf
and then run:
sudo sysv-rc-conf
Xorg
This is just a general tip. I will not tell you what to remove. You know best what you need…
If you strip down the xorg.conf you can decrease the amount of resources that xorg will use.
sudo kate /etc/X11/xorg.conf
Remove any unnessesary fontpaths, modules and the wacom devices (unless you need them).
By removing the wacom devices you will also get rid of those anoying errors that usually prints out in the console whenever you run an application.
Kernel hacking
Even thought the new kernel in feisty is very good and already tuned a bit there still are some things you can do to the kernel that will make your system snappier and boot up even faster.
Use this thread from the ubuntu forums as a guide on how to compile your own kernel.
master kernel thread
What I do is that I make sure to add the file systems and drivers I use to the kernel instead of loading them as modules. Take out whatever I don’t have or use and then compile my new and hopefully improved kernel 
If you don’t want to compile your own kernel there is now a low-latency kernel in the universe repos that you could try.
Disk and file system setup
This is probably the most important thing to think about when you are about to install your computer. The choice and use of the disks and file system is a huge issue when dealing with performance. Depending on your usage of your system you might need to configure your file system different.
For my usage I like to use the following setup (which I think is a good desktop setup).
| Mountpoint | File system | Size |
|---|---|---|
| /boot | ext2 | 100 MB |
| / | LVM, VG=system, XFS | 6 GB |
| /swap | LVM, VG=system, swap | The size of RAM in your computer. Making it smaller and you will not be able to hibernate. |
| /home | LVM, VG=system, XFS | 1 GB, or the rest of the space in that VG |
| /data | LVM, VG=data, XFS | The rest of the free space |
I’m using the following options in fstab for all my xfs partitions:
noatime,nodiratime,logbufs=8
Using LVM can really speed up the disk performance. And you get a lot of other good stuff with it as well. Read more about LVM here.
I choose to have /root and /home on one VolumeGroup and /data on another simply because I can then split them up on different physical disks and have them spanning over multiple physical disks witch really speeds up the reads and writes.
What about hdparm?
I have not found any use for hdparm on SATA disks (seems to lack support for SATA). But on older disks there are some things you could tune with hdparm.
Anyhow, since I don’t use it I won’t give you any example on how to use it. Simply search for hdparm on the net and you will find plenty
At the moment this is pretty much it but I will update this guide as soon as I discover more performance tunings…
At the moment there is not so much to add here but this what I like to do.
Firefox
Use swiftfox instead. It’s optimized for your CPU.
If it’s not already set, disable ipv6. In the url enter about:config and find the ipv6 entry and disable it. And while you are at it change the ui.allow_platform_file_picker to false to change the file dialogs to look a little bit better (if you are a KDE user like me).
Addons I use:
MediaPlayerConnectivity
Opens video stream directly in an external video player
fasterfox
A nice gui to tweak the performance of the browser
adblock plus
to disable ad’s it helps a lot
Mouse gestures
Cause it makes the surfing a lot easier…
Theme:
KDEFF
Gives it a little bit more of a KDE look and feel…
Openoffice
If you don’t need that extras that java JRE provides then simply disable it openoffice. That’s what I do.
I followed this guide and managed to screw up, now I can’t boot…
Hey, what can I say. Life’s a bitch…
Well ok then. Here’s something that might help.
Boot up your computer with the Feisty desktop cd
mount your root file system and change/restore your files again.
If you are using LVM then apt-get install lvm and then run vgchange -ay to activate your LVM volumes before you can mount them.

Gmail 受到许多人的追捧，其中很大一部分原因就在于它为用户提供了海量的邮箱空间。事实上，对于普通用户而言，仅会占用其很少的容量。或许我们可以将 Gmail 变成自己的网络硬盘以便随处使用。
要实现上述设想，有一个 Firefox 扩展就可以办到，它的名字是 Gspace。这是一个充满创意，并且非常实用的 Firefox 扩展。我在试用之后很快便喜欢上了它，并成为了我以后必装的 Firefox 扩展之一。
Gspace 可以将 Gmail 变成一个在线存贮空间，方便我们将文件、资料、音乐、图片等存入其中。除了存贮功能之外，使用 Gspace 你也能够直接播放所存贮的音乐，查看所存贮的图片。利用 Gspace，我们就可以把重要的东西存入 Gmail 空间，以做到有备无患。
安装 Gsapce
Gspace 的安装过程与其他的 Firefox 扩展并无二致，从 Gspace 的下载页面上点击适用于 Linux 系统的链接，之后按照提示即可完成安装。在安装完成后，需要重新启动 Firefox 方能开始使用。
建立 Gspace 帐户
在使用 Gspace 存贮文件之前，你需要将有效的 Gmail 帐号信息提供给 Gspace。点击“Tools -> Gspace”菜单命令可以打开 Gspace 控制窗口。然后，单击左上角的“Manage Accounts”按钮可以添加一个新的 Gspace 帐号。在建立帐号时，需要输入你的 Gmail 帐号及密码。
上传文件
如果你有使用 FTP 客户端的经历，那么在 Gsapce 中上传文件将不在话下。先选择左边的本地文件，再按中间的上传按钮即可将文件上传到 Gmail 空间中。如果是下载文件，其过程与此类似。
听音乐，看图片
这个首先要保证你的 Gmail 空间中存贮有音乐、图片这些东西。然后只需将 Gspace 的文件传输模式切换成相应的 Player Mode 和 Photo Mode 即可。另外，还有一个 Gmail Drive Mode，不过我在试用时发现存在不小的问题，要慎用。
Gspace 还有一个迷你窗口，可从状态栏中的图标处打开。
