i want write simple diff application in python using google's diff match patch apis . i'm quite new python, want example of how use diff match patch api semantically comparing 2 paragraphs of text. i'm not sure of how go using diff_match_patch.py file , import it. appreciated! additionally, i've tried using difflib , found ineffective comparing largely varied sentences. i'm using ubuntu 12.04 x64. google's diff-match-patch api same languages implemented in (java, javascript, dart, c++, c#, objective c, lua , python 2.x or python 3.x). therefore 1 can typically use sample snippets in languages other one's target language figure out particular api calls needed various diff/match/patch tasks . in case of simple "semantic" comparison need import diff_match_patch texta = "the cat in red hat" textb = "the feline in blue hat" #create diff_match_patch object dmp = diff_match_patch.diff_match_patch() # depending...

came across question, similar not @ same since talks java, has different implementation of hash-tables, virtue of having synchronized accessor /mutators differences between hashmap , hashtable? so difference in c++ implementation of set , unordered_set ? question can ofcourse extended map vs unordered_map , on other c++ containers. here initial assessment set : while standard doesnt explicitly asks implemented trees, time-complexity constraint asked operations find/insert, means implemented tree. rb tree (as seen in gcc 4.8), height-balanced. since height balanced, have predictable time-complexity find() pros : compact (compared other ds in comparison) con : access time complexity o(lg n) unordered_set : while standard doesnt explicitly asks implemented trees, time-complexity constraint asked operations find/insert, means implemented hash-table. pros : faster (promises amortized o(1) search) easy convert basic primitives thread-safe, compared tree-ds co...

eclipse juno regularly resets of settings (.metadata). starts clear desktop if installed. need restore .metadata once week or two. why happen? known eclipse problem? updated this happens every time when switch off second display. do not put .metadata under version control. put contents of workspace (i.e. projects) under version control. manipulating .metadata directory during checkouts, breaking workspace yourself. the metadata directory cannot shared design , lead trouble. see what of eclipse project .metadata can safely ignore in git/mercurial? or which eclipse files belong under version control? more pointers that.

i want implement client application information of weblogic server. communication has secure because weblogic server configure secure. now i'm able establish ssl communication. following settings: system.setproperty("weblogic.security.trustkeystore", "customtrust"); system.setproperty("weblogic.security.customtrustkeystorefilename", tmptruststore.getabsolutepath()); system.setproperty("weblogic.security.customtrustkeystorepassphrase", "somepw"); system.setproperty("weblogic.security.customtrustkeystoretype", "jks"); it possible weblogic ssl communication accept certificates? make application more convenient in handling. think of solution similar override of x509trustmanager. if so, can give me example? otherwise can give me answer reasons? no not possible. having ssl connection between 2 entities in 1 accepts data defeats purpose of having secure connection. either use non-ssl port convenience...

i have web application reads contents of web page , parses sentences using nlp algorithm. have been using regex split contents single sentences , parsing them. i remove characters  sentences. these characters, imagine, because of html encoding. i cannot use regex [^\w\d]+ or variations because need punctuations intact. of course add individual exceptions each of punctuation [^\w\d\.,:]+ , on, if there easier way this, character class knows a... funny character? any appreciated. thanks. edit: app built php , using simple file_get_contents() fetch html data site , reading contents inside <p> tags. this mentioned in comments @thegreatco able create character class of "special" characters. can use hex code values create range in character class. special character on ascii 127 this.

i using networkx , matplotlib now want set color of nodes,and read graph text file g=nx.read_edgelist("edge.txt") nx.draw(g) plt.show() here edge file of example 0 1 0 2 3 4 here did,and failed import networkx nx import matplotlib.pyplot plt g = nx.read_edgelist("edge.txt") pos = nx.spring_layout(g) nx.draw_networkx_nodes(g,pos,node_list=[0,1,2],node_color='b') nx.draw_networkx_nodes(g,pos,node_list=[3,4],node_color='r') plt.show() the result lot of blue nodes without edges so if want set nodelista=[0,1,2] blue, nodelistb=[3,4] red how can that? draw nodes explicitly calling top-level function, draw_networkx_nodes and pass in node list value parameter node_list , , value parameter node_color , so nx.draw_network_nodes(g, pos, node_list=nodelista, node_color="#5072a7") the argument pos python dictionary keys nodes of graph , values x, y positions; easy to supply pos pass graph object spring_layout retu...

using spring jndi look-up our data access requirements. making calls multiple stored procedures (in sybase). wanted way control auto-commit property of transactions while calling these stored procs. able achieve basicdatasource (property name="defaultautocommit"). got stuck when moved doing jndi look-up (from weblogic). <jee:jndi-lookup jndi-name="wl_data_source" id="datasource" /> <bean id="procedurehandlerbean" class="myclass"> <property name="procdatasource" ref="datasource"/> </bean> after researching few days, appears me can use jtatransactionmanager. however, not sure if can use transaction manager configure auto-commit on per procedure call basis (due different chained/unchained mode requirements of different procs). there clean way achieve this?

i have problem access network share drives mapped in explorer software if runs administrator rights. if disable uac runs well, can enumerate network drives mapped in explorer. my question is: how can accesss network drives or enumerate them when uac on? i tried change: localaccounttokenfilterpolicy in registry, doesnt work. any solutions? with kind regards xen the problem not uac per se, nor running administrator rights . problem you're running under different user account . "run administrator" that. each user account has own network shares. when you're running different user, therefore enumerate different shares. try running explorer.exe different user; you'll see explorer.exe find same shares do. this not worked around, design. it's harder malware spread when each user account can access drives , shares needs. the correct solution not run uac/administrator rights. if really, need to, it's 1 single administrative task. tas...

i'm doing simple test (attempting null check value) , kicks decided null check make believe / nonexistant value: "striiing" not exist anywhere in source code. checked logcat , realized non existent value appears as: 04-18 04:40:22.197: d/com.game.demo.level1(15800): broken value! debug! debug! when executing following: if ("striiing" != null) { log.d(tag, "broken value! debug! debug!"); prefs.getboolean("name", true); prefs.getboolean("player", true); prefs.getboolean("points", true); prefs.getboolean("level", true); prefs.getboolean("gear", true); can explain why non existent value could/would show being not null? it's quite bizarre. "striiing" string literal, non null object in java. try instead: string s = null; if (s == null) ... and should work expected.
