i have table in pandas/python , doing following: grouped_data = df_comments_cols['article_id'].groupby(df_comments_cols['user_id']) now count number of articles per user following: ct_grouped_data = grouped_data.count() the above counts number of article ids per user. however, there multiple of same article ids per user (in sense user has interacted article more once) , wish count unique article ids per user - there quick way this? thanks in advance. i think might looking nunique , can call on groupby objects so: in [63]: df = dataframe({'a': randn(1000, 1)}) in [64]: df['user_id'] = randint(100, 1000, size=len(df)) in [65]: df['article_id'] = randint(100, size=len(df)) in [66]: gb = df.article_id.groupby(df.user_id) in [67]: gb.nunique() out[67]: user_id 100 2 101 1 102 1 104 2 105 1 106 2 107 1 110 1 111 4 112 2 113 1 114 2

i have sql query want retrieve timestamp records table. the query must return time without time zone if todays date = timestamp in record. if record's timestamp::date not equals todays date return timestamp. examples: 2013-08-07 18:00:18.692+01 2013-08-09 20:13:09.927+01 expected result: 18:00:18.692 2013-08-09 20:13:09.927+01 from 2 timestamps able retrieve time 1st todays date retrieve both date , time second not todays date this formatting issue, might better handle in application code. can in sql. create table t ( ts timestamp not null ); insert t values ('2013-01-01 08:00'); insert t values (current_timestamp); the time , timestamp data types aren't compatible in way want return them, casting text makes sense. select case when ts::date = current_date ts::time::text else ts::text end t; ts -- 2013-01-01 08:00:00 16:34:52.339

so ran issue goes follows: - have table a. - have table b has foreign key table a. - have trigger on table ensures every item in table has @ least 1 row in table b pointing (through foreign key). - trigger runs "insert" commands. issue when insert table a, trigger raises error because table b doesn't have row foreign key new row in table yet. row on table b inserted end of transaction trigger not give me chance. solution problem? there way tell trigger run after last command in transaction executed? if need trigger fire on table a, not know if there corresponding rows in table b, should use "instead of" trigger. allow check table b before inserting rows table a. if there match in table b, proceed insert a, otherwise, add row b , a, or skip data doesnt match , return error application. http://msdn.microsoft.com/en-us/library/ms175521(v=sql.105).aspx

i can't seem wix cabinet caching work. i have <propertygroup> <cabinetcreationthreadcount>3</cabinetcreationthreadcount> <cabinetcachepath>cabs</cabinetcachepath> <reusecabinetcache>true</reusecabinetcache> </propertygroup> in wixproj. <media id="1" cabinet="contents.cab" embedcab="yes" compressionlevel="mszip"/> <media id="2" cabinet="static.cab" embedcab="yes" compressionlevel="mszip"/> in wxs and component know 100% never ever changes marked <component diskid="2" ... i see cab files generated in cabs directory, each time build, see modified time of cab file change, suggests it's regenerated cabinet instead of reusing 1 cache. using wix 3.6 how can working or debug problem further? are building or rebuilding (i.e. /t:build or /t:rebuild )? wix import remove generated fil

my last question got me thinking. 1) select count(*) count foo bar = 123; if count > 0 select var foo bar = 123; -- stuff else -- other stuff end if; 2) begin select var foo bar = 123; -- stuff exception when no_data_found --do other stuff end ; i assume number 2 faster because requires 1 less trip database. is there situation 1 superior, not considering? edit: i'm going let question hang few more days, gather more votes on answers, before answering it. if use exact queries question 1st variant of course slower because must count records in table satisfies criteria. it must writed select count(*) row_count foo bar = 123 , rownum = 1; or select 1 row_count dual exists (select 1 foo bar = 123); because checking record existence enough purpose. of course, both variants don't guarantee else don't change in foo between 2 statements, it's not issue if check part of more complex scenario. think situati

i'm having trouble scipy.optimize.fmin , scipy.optimize.minimize functions. i've checked , confirmed arguments passed function of type numpy.array, return value of error function. also, carreau function returns scalar value. the reason of arguments, such size, this: need fit data given model (carreau). data taken @ different temperatures, corrected shift factor (which fitted model), end several sets of data should used calculate same 4 constants (parameters p). i read can't pass fmin function list of arrays, had concatenate data x_data_lin, keeping track of different sets size parameter. t holds different test temperatures, while t_0 one-element array holds reference temperature. i positive (triple checked) arguments passed function, result, one-dimensional arrays. here's code aside that: import numpy np import scipy.optimize scipy.optimize import fmin simplex def err_func2(p, x, y, t, t_0, size): result = array([]) temp = 0 in range(0, int(len
