in java project i'm using 2 different frameworks (let's a.jar , b.jar) , both of them require 1 common framework (let's log4j.jar) in 2 different versions. how treated java if framework needs log4j v1.1 , b needs log4j v1.2? cause kind of conflict/error or somehow (how?) resolved? if not cause conflict/error (my project can compiled , run) - can use version of log4j myself in project? or forced select lower / higher version number of log4j? update: to more specific... if part of log4j api changed in v1.2 (let's 1 single method doit() signature changed) , both , b call doit. happend? project run? crash on first use of doit? version of log4j must put on classpath - v1.2 or both? java doesn't natively support management of multiple versions of same piece of code, is, can use @ 1 version within same jvm (with default class loader). however, checkout question 1705720 , has several answers pointing out possible ways of achieving (osgi or custom class l...

in several php applications i'm making need maintain long query string filters table. want change 1 or more variables per filter change, while rest of query string stays unchanged. i have few ideas on how this, including using javascript build query string every time filter changed, or maintaining query string in session variable, changing there. i opinions or experience on how best way be. thanks! yes, use associative array store map of keys values. can change 1 easily. these supported in both php , javascript, you're good. you'll need write functions output array query string. i did on lark once (and every time): alphabetize (or otherwise order) parameters in query string. why? convenient if same page has same url/query string. if write tests, it's easier assert query strings match. otherwise, @ mercy of associative array implementation's traversal order.

i'm using postgresql 8.1.17, , have table account numbers. acceptable range account number number between 1 , 1,000,000 (a 6 digit number). column "acctnum" contains account number. selecting numbers in use easy (select acctnum tbl_acct_numbers order acctnum). select numbers in acceptable range not in use, is, aren't found in rows within column acctnum. select new_number generate_series(1, 1000000) new_number left join tbl_acct_numbers on new_number = acctnum acctnum null;

is nasty subversion bug or approaching wrong way? merge branch trunk. ->helloworld.txt updates revert helloworld.txt do same merge again. ->no files update. why doesn't second merge update helloworld again? it's acting if change has been copied over. shouldn't revert reset it? if revert entire folder helloworld in, second merge applies change again. it's if revert file fails. this little scary. if need revert files now. future merge silently fail copy on critical code. subversion 1.6 os x 10.6.4 subversion performs merge tracking, meaning record revisions have been merged. merge info recorded in property called svn:mergeinfo on root of merge (ie whatever entered target after svn merge ). reverted file, didn't revert merge root contains modified or added svn:mergeinfo property.

i want select bunch of data table using group by clause. works great, need order data date created, order by clause. question is, can use both these clauses within same query, or should using 1 in sub-query, or else? the original query (no modification) this: select * table tag_draft=0 , ( (target_id=2 , tag_del_target=0) or (source_id=2 , tag_del_source=0) ) , updated in ( select max(updated) table group thread_id ) order updated desc hopefully question readable enough able answer it. the mysql select syntax is: select [all | distinct | distinctrow ] [high_priority] [straight_join] [sql_small_result] [sql_big_result] [sql_buffer_result] [sql_cache | sql_no_cache] [sql_calc_found_rows] select_expr [, select_expr ...] [from table_references [where where_condition] [group {col_name | expr | position} [asc | desc], ...

for reason onpause method not getting called when app put background. either or mylocationoverlay not disabling. my app uses google maps , mylocationoverlay . when starting app, call mylocationoverlay.enablemylocation() in onresume method. in onpause method call mylocationoverlay.disablemylocation() . however, when hit home key or key go home screen, gps stays running indicated top of status bar gps icon. edit: not work on either emulator or phone. edit2: gps icon goes away when use advanced task killer kill it. edit3: onpause being called put log statement in it, gps icon remains. therefore looks either gps service isn't shutting down, or mylocationoverlay has bug disablemylocation() method. here manifest file , excerpts activity: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" xmlns:myapp="http://schemas.android.com/apk/res/com.tfb" package="c...

i trying find functions in rails api docs. example, in console can type in: activerecord::base.connection.tables activerecord::base.connection.indexes("sometable") and list of tables , list of indexes. in rails api doc http://api.rubyonrails.org/classes/activerecord/base.html cannot find reference either of these. i find connection() trail ends there! little figuring out apis! thanks... activerecord::base#connection internally relies on activerecord::base.connection (class method) return concrete implementation of activerecord::connectionadapters::abstractadapter class. you should search #indexes method in concrete adapter, instance postgresqladapter#indexes . rdoc doesn't provide hint on object type returned method call. should dig source code or have deep understanding of package itself. there alternatives such yard generates more complete api documentation. there's rails searchable api doc project offers searchable rails...

when querying in django people.objects.all(pk=code) , pk=code mean? it's query people object has primary key of whatever value of "code" is. by default, django model instances have primary key uniquely identifies object. it's auto-incrementing integer, define whatever want, long it's unique. http://docs.djangoproject.com/en/dev/topics/db/models/#id1 edit: @ code snippet little closer, rather assuming said, doesn't make sense. all() method should get(). doesn't make sense give pk all() since returns objects of type. http://docs.djangoproject.com/en/dev/ref/models/querysets/#all http://docs.djangoproject.com/en/dev/ref/models/querysets/#id5

i kind of new triggers , cant figure out how resolve this. after insert new row on specicfic table should influence other tables aswell. so if add(insert) order on table includes 3 quantity, want 3 less in_stock in table(column)... in advance assuming column , table names (order table column name : quantity , product_id key uniquely used identify order) .. should job create or replace trigger trg_update_available after insert on orders each row begin update in_stock set quantity = quantity - :new.quantity product_id = :new.product_id; end; / note : commit; still present in code insert order.

i have strings such as ["tabula rasa", "façade", "dj tiësto"] i'm accessing google ajax api in python using base url: base = 'http://ajax.googleapis.com/ajax/services/search/web' '?v=1.0&q=%s' i'm having issues using these strings plain , noticed have transform characters, eg. "tabula rasa" --> "tabula%20rasa" but have huge list of these strings , not know of way can automatically prepare these string url query. any appreciated. what you're looking urllib.quote(): >>> urllib.quote("tabula rasa") 'tabula%20rasa' the non-ascii strings may need recoded encoding expected google ajax api, if don't have them in same encoding already.
