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 :

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

第一次洗澡

前天, 也就是10月5日, 宝宝第一次洗澡, 他有点害怕, 腿直挺挺的伸着, 小手用力抓着游泳圈, 一动也不动, 就像蒸了一个桑拿, 坚强的宝宝一直没有哭.

脐带掉了

昨天宝宝的脐带掉了

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 - 6 python operators

结果在这里: http://docs.python.org/library/operator.html

知道这些, 我们就可以像c那样重载操作符了

这应该也算是descriptor的一种吧

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)

... def __sub__(self, t):

... return id(t)

...

>>> c = a()
>>> 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|""

12492856

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?

trac代码阅读3 - upgrade database

重写IEnvironmentSetupParticipant中的三个方法, 然后记得在__init__.py中import 你的IEnvironmentSetupParticipant实现, 此时安装并启用插件之后, 就会出现: trac-admin /path/to/trac upgrade的提示

trac代码阅读2 - yield expressions

例:

def test(value = None):

i = value or 0

while i < 100:

yield i

i += 1

=============>>>>>

>>> s.next()

由外部逻辑控制此generator function的执行, we called it: Semi-Coroutine
