硬盘多了, 分区多了, 想获得每个分区的uuid来统一管理一下:
$# blkid /dev/hdb5
/dev/hdb5: UUID="6fa9e80b-5eba-42b1-994b-6fd76158335e" SEC_TYPE="ext2" TYPE="ext3"

赤壁怀古
赤壁怀古
苏 轼
大江东去，浪淘尽、千古风流人物。故垒西边，人道是、三国周郎赤壁。乱石崩云，惊涛裂岸，卷起千堆雪。江山如画，一时多少豪杰！
遥想公瑾当年，小乔初嫁了，雄姿英发。羽扇纶巾，谈笑间、樯橹灰飞烟灭。故国神游，多情应笑我、早生华发，人生如梦，一尊还酹江月。

解决linux下firefox中flash插件乱码问题
解决linux下firefox中flash插件乱码问题, 转自: http://roclinux.cn/?p=1189
在Linux下用Firefox浏览有Flash的网页时，经常碰到有些文字不能正常显示，有些还可能显示乱码，比如Google 的在线音乐播放音乐时，完全显示不了文字。
解决方法很简单，操作如下：
修改/etc/fonts/conf.d/49-sansserif.conf
<?xml version="1.0"?> <!DOCTYPE fontconfig SYSTEM "fonts.dtd"> <fontconfig> <!-- If the font still has no generic name, add sans-serif --> <match target="pattern"> <test qual="all" name="family" compare="not_eq"> <string>sans-serif</string> </test> <test qual="all" name="family" compare="not_eq"> <string>serif</string> </test> <test qual="all" name="family" compare="not_eq"> <string>monospace</string> </test> <edit name="family" mode="append_last"> <string>sans-serif</string> </edit> </match> </fontconfig>将上面的红色的内容改为：
<string>sans</string> 保存一下，在firefox里刷新一下，问题就解决了。

雪
| 《沁园春•雪》（1936年2月） | |
北国风光，千里冰封，万里雪飘。 江山如此多娇，引无数英雄竞折腰。 |

自动构建java jar library path命令
在指定目录运行此命令:
find ./ -name '*.jar'|paste -s -d :
find ./ -name '*.jar'|paste -s -d :
输出:
./spider.jar:./lib/nekohtml.jar:./lib/poi-scratchpad-3.0.1-FINAL.jar:./lib/jdom.jar:./lib/hessian-3.1.5.jar:./lib/hibernate3.jar:./lib/dom4j-1.6.1.jar:./lib/htmlparser.jar:./lib/jetty-6.1.9.jar:./lib/jstl.jar:./lib/log4j-1.2.11.jar:./lib/commons-pool-1.3.jar:./lib/cglib-2.1.3.jar:./lib/mysql-connector-java-5.0.5.jar:./lib/jaas.jar:./lib/chardet.jar:./lib/commons-validator.jar:./lib/standard.jar:./lib/FontBox-0.1.0.jar:./lib/jakarta-oro.jar:./lib/commons-fileupload.jar:./lib/jboss-common.jar:./lib/PDFBox-0.7.3.jar:./lib/commons-httpclient-3.1-rc1.jar:./lib/antlr-2.7.5H3.jar:./lib/antlr.jar:./lib/jboss-cache.jar:./lib/struts.jar:./lib/asm.jar:./lib/connector.jar:./lib/xml-apis.jar:./lib/asm-attrs.jar:./lib/jboss-jmx.jar:./lib/rome-0.9.jar:./lib/c3p0-0.9.0.jar:./lib/jetty-util-6.1.9.jar:./lib/ehcache-1.1.jar:./lib/servlet-api-2.5-6.1.9.jar:./lib/commons-digester.jar:./lib/commons-logging.jar:./lib/cpdet.jar:./lib/bcprov-jdk14-132.jar:./lib/ibatis-2.3.0.677.jar:./lib/jacc-1_0-fr.jar:./lib/eucita-common-0.7.1.jar:./lib/lucene-core-2.3.0.jar:./lib/commons-collections-2.1.1.jar:./lib/xerces-2.6.2.jar:./lib/commons-dbcp-1.2.2.jar:./lib/commons-lang-2.3.jar:./lib/poi-3.0.1-FINAL.jar:./lib/icu4j-3_8.jar:./lib/proxool-0.8.3.jar:./lib/jboss-system.jar:./lib/oscache-2.1.jar:./lib/db4o-6.3-java5.jar:./lib/concurrent-1.3.2.jar:./lib/commons-logging-1.0.4.jar:./lib/jgroups-2.2.8.jar:./lib/mail-1.4.jar:./lib/commons-beanutils.jar:./lib/swarmcache-1.0rc2.jar:./lib/jdbc2_0-stdext.jar:./lib/log4j-1.2.9.jar:./lib/jaxen-1.1-beta-7.jar:./lib/commons-codec-1.3.jar:./lib/bcmail-jdk14-132.jar:./lib/jta.jar
这样就可以自动构建java 的library path

shelve
import shelve d = shelve.open(filename) # open -- file may get suffix added by low-level # library d[key] = data # store data at key (overwrites old data if # using an existing key) data = d[key] # retrieve a COPY of data at key (raise KeyError if no # such key) del d[key] # delete data stored at key (raises KeyError # if no such key) flag = d.has_key(key) # true if the key exists klist = d.keys() # a list of all existing keys (slow!) # as d was opened WITHOUT writeback=True, beware: d['xx'] = range(4) # this works as expected, but... d['xx'].append(5) # *this doesn't!* -- d['xx'] is STILL range(4)! # having opened d without writeback=True, you need to code carefully: temp = d['xx'] # extracts the copy temp.append(5) # mutates the copy d['xx'] = temp # stores the copy right back, to persist it # or, d=shelve.open(filename,writeback=True) would let you just code # d['xx'].append(5) and have it work as expected, BUT it would also # consume more memory and make the d.close() operation slower. d.close() # close it

trac源代码阅读 - 5 python operators
__add__ == +
>>> class a(object):
... def __or__(self, t):
... return id(t)
... def __add__(self, t):
... return id(t)
...
>>> c = a()
>>> a()+c
13041552
>>> id(c)
13041552
__sub__ == -
>>> class a(object):
... def __or__(self, t):
... return id(t)
... def __add__(self, t):
... return id(t)
...
>>> c = a()
>>> a()+c
13041552
>>> id(c)
13041552
__sub__ == -
>>> class a(object):
... def __or__(self, t):
... return id(t)
... def __add__(self, t):
... return id(t)
... def __sub__(self, t):
... return id(t)
...
>>> c = a()
>>> a()-c
13041552
>>> id(c)
13041552
>>> a()-c
13041552
>>> id(c)
13041552
why? will continue in next post.
trac源代码阅读 - 4 ("|" or operator)
__or__ == |
Error:
>>> a={'a':1, }
>>> b = lambda x: x*2
>>> a | b
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for |: 'dict' and 'function'
the first object must has "__or__" method
Right:
>>> class a(object):
... def __or__(self, t):
... return id(t)
...
>>> c = a()
>>> d = a()
>>> c|d
13041232
>>> id(c)
13041264
>>> id(d)
13041232
>>> c|""

innerHTML中, p包含ul的问题
一个dom节点给他innerHTML="<p class='temp'><ul><li>test</li></ul></p>", 其中temp的样式为: .temp {display:none;}, 此时ul元素会被解析到p标签之外, IE, FF, Chrome都是如此, BUG or Standard?
