Setting the Egg Cache Directory
If you try to start apache right now you will receive an error like this one:
ExtractionError: Can't extract file(s) to egg cache
The following error occurred while trying to extract file(s) to the
Python egg cache:
[Errno 13] Permission denied: '/var/www/.python-eggs'
The Python egg cache directory is currently set to:
/var/www/.python-eggs
Perhaps your account does not have write access to this directory?
You can change the cache directory by setting the PYTHON_EGG_CACHE
environment variable to point to an accessible directory.
The problem comes from the fact thatmod_python needs to unzip the required eggs before your application canuse them, but for this the user under which apache runs needs to havewrite access to the specified directory.
There are diverse solutions to solve this problem. 1. The first would be to give write access to the apache user to this /var/www/.pytho We won't talk about the first solution because it is NOT an option in a production environment. The second option to install all TurboGears dependency by specifying that you want them unzipped can be realised doing so: easy_install -UZ kid tomake sure that kid is installed unzipped intead of inside a zipped egg.Then repeat the operation for each egg that you see in the<Python_Root>/s The third option is a bit different since you will set an environment variable to be picked up by apache: mkdir -p /tmp/turbogears it is your responsibility to correctly secure this /tmp/turbogears
2. The second way is to install all eggs unzipped to avoid the need to have a directory writable by apache.
3. The third way is to specify before running apache were the apache user should unzip the eggs.
export PYTHON_EGG_CACH
apachectl start
I have seen informations about using a PythonOption to set the PYTHON_EGG_CACH

感觉ubuntu的性能还是没debian那么好。今天决定来次清洗，把许多不必要的功能卸掉或者关掉。猴年马月要用到了，再来装吧。
1. Games
在新立得里选games类软件，除了games-common之外，其余小游戏全部卸掉，因为我不玩。
2. Evolution邮件
因为通常都用在线邮箱，出于系统安全的原因，不太喜欢用这类软件。把Evolution卸掉：
evolution
3. Brasero光盘刻录
没有刻录机。
brasero
4. 蓝牙
bluetooth
bluez
bluez-alsa
bluez-cups
bluez-gstreamer
bluez-utils
gnome-bluetooth
5. 系统服务：

需求:
需要把一个字符(ASCII或Unicode)转换为数字编码
讨论:
对于ASCII字符,可以使用内建的ord和chr方法实现需求:
>>> chr(97)
‘a’
>>> ord(’a')
97
对于Unicode字符,需要使用ord和repr
>>> print ord(u’\u2020′)
8224
>>> print repr(unichr(8224))
u’\u2020′
相关说明:
下面是python中对这几个方法的简单说明:
ord(…)
ord(c) -> integer
Return the integer ordinal of a one-character string.
chr(…)
chr(i) -> character
Return a string of one character with ordinal i; 0 <= i < 256.
repr(…)
repr(object) -> string
Return the canonical string representation of the object.
For most object types, eval(repr(object)) == object.
unichr(…)
unichr(i) -> Unicode character
Return a Unicode string of one character with ordinal i; 0 <= i <= 0×10ffff.
