i have 2 dataframes, each having 100,000 rows. trying following: new = dataframea['mykey']/dataframeb['mykey'] and 'out of memory' error. same error if try: new = dataframea['mykey'].divide(dataframeb['mykey']) but if loop through each element, this, works: result = [] idx in range(0,dataframea.shape[0]): result.append(dataframea.ix[idx,'mykey']/dataframeb.ix[idx,'mykey']) what's going on here? i'd think built-in pandas functions more memory efficient. @ayhan got right off bat. my 2 dataframes not using same indices. resetting them worked.

how can make sure load data via view composer select views , exclude few, 2 views specific? can use regex instead of '*'? public function boot() { view()->composer( '*', 'app\http\viewcomposers\profilecomposer' ); } there 2 views i'd avoid, extend same blade used others, not sure declaring 99 others best - if can define ones left out that'd great. perhaps not best way doing can done this in services provider register view composer public function boot() { view()->composer( '*', 'app\http\viewcomposers\profilecomposer' ); } in profilecomposer compose method view class repository type hinted. use name of current name of view , make condition excluded view name. class profilecomposer { public function __construct() { // dependencies automatically resolved service container... } /** * bind data view. * * @param view $vie...

i've asked several developers, , gotten different answers every time. let's i'm working in mvc framework , have class called validator . object has bunch of methods can used tell if email or phone number valid, or if given value has content in it. say want make service property of model i'm creating. can inject construction method of model class. however, service fit in in mvc? model? where should file stored? models? in it's own directory, perhaps called services ? i think have different view [sadly no pun intended] of model in mvc, services should go in model layer. first, model shouldn't class. model a model, of one application. application modelized in different things (contained in model layer): entities, mappers, services. for exemple, file hierarchy representing concept: application controller model entities mappers services view say want make service property of model i'm creating....

as see it, both 'mars%22%3a%22' , "mars%22%3a%22" equivalent, nothing being escaped. i have been creating javscript bookmarklet time now. @ 1 point, stopped working when pasted as-is bookmark in chrome. i discovered solution after guess-and-check: a pair of double quotes needed single quotes. why? the following line single-quotes inside split() causes no problems in bookmarklet: loaddoc("/page1/" + aarray[i].href.split('mars%22%3a%22')[1].slice(0,7),i); the line below double quotes cause bookmarklet not run @ all: loaddoc("/page1/" + aarray[i].href.split("mars%22%3a%22")[1].slice(0,7),i); no error shown in console. note double-quote version run fine if pasted javascript console directly! what not understanding? javascript not distinguish between single , double quotes in way language ruby (where string interpolation , backslash escape sequences work in double-quoted string). both types of quote ha...
