is there difference between following code, speed wise or preference? $sql = "select * users username=?"; $user = $database->prepare($sql); $user->execute(array(request::post('username'))); vs $user = $database->prepare("select * users username=?"); $user->execute(array(request::post('username'))); i have not tried benchmarking, visual difference less amount of code, why should 1 rather other, or should both? $sql = "select * users username=?"; $user = $database->prepare($sql); $user->execute(array(request::post('username'))); vs $user = $database->prepare("select * users username=?"); $user->execute(array(request::post('username'))); if using select statement once, don't put in variable, lessen memory , process used in creating variable , storing value. $sql = "select * users username=?"; if using more once, can use variables avoid repetitive in

unlike previous question , want on commandline (just grep). how can grep every number text file , display results? sample text: this sentence 1 number, while number 2 appears here, too. i expect able extract "1" , "2" text (my actual text substantially longer, of course). i think want this, $ echo 'this sentence 1 number, while number 2 appears here, too.' | grep -o '[0-9]\+' 1 2 since basic sed uses bre ( basic regular expression ), need escape + symbol repeat previous character 1 or more times.

i've inherited system has several tables of form this: create table notes ( id int primary key, note text, parent_id int, parent_type varchar ); basically, idea have several other types, "tickets" , "widgets", , if want add note ticket 123, you'd do: insert notes (note, parent_id, parent_type) values ('blah blah', 123, 'ticket'); is there sensible way have jpa create @onetomany relationships from, say, ticket note schema? or need split notes table out separate ticket_notes, widgets_notes, etc tables? would possible create separate ticketnotes, widgetnotes, etc entities in java using @discriminatorcolumn , perhaps? it seems taking advantage of discriminators , inheritance gets me want. for example: @entity class ticket { @id private integer id; // ... @onetomany(mappedby="ticket", fetch=fetchtype.lazy) private list<ticketnotes> notes; } @entity @inheriten

hi i'm trying create single image multiple images in opencv. images use same size. what reshaping them single line , try merge them new image. i create new image size of 2 images , pass array recieve error exc_bad_access(code=1, address = ..) note: sizes of images correct size of single image : [170569 x 1] size of new_image : [170569 x 2] my code below. thank you int main(){ mat image[2]; image[0]= imread("image1.jpg",0); image[1]= imread("image2.jpg",0); image[0] = image[0].reshape(0, 1); //single line image[1] = image[1].reshape(0, 1); //single line int size = sizeof(image)/sizeof(mat); mat new_image(image[0].cols,size,cv_32fc1,image); } if understand need concatenate 2 image of same size 1 mat. wrote quick code perform task. u can change argument function pointer , add other handlers care variant size image. #include <iostream> #include <opencv2/opencv.hpp> #include <opencv2/hi

during course of regular agile programming technique, lot of refactoring. if find common things candidates base class. assume code pattern: public subclass : baseclass{ private dynamic somevalue = null; public subclass(){ somevalue = baseclass.method<t>(); } } everything works fine until tired of continually injecting type method. why not inject type base class instead? wait second, don't want have redo 20 classes using pattern above. have 2 potential patterns can use, being second. public subclass : baseclass<t>{ private t somevalue = null; public subclass(){ somevalue = baseclass.method(); } } this second pattern logical derivation of first example whereby merely moving type class ctor instead of using generic type in each method. i ask community thoughts on how accomplish both constructs without changing current code adding in support of generic type baseclass pattern. i have read other posts on "optional generic

i want use gsa serve search results google groups. i lot of research in web did not found information gsa , google groups. understood google groups use #! (hashbang) in url , gsa doesn't support crawling ajax applications. i think solutions use integrating google apps method on this, , other similar, article talk google sites , google docs , not google groups. because try solution have involve various departments in company know if used method that. or if give me advices achieve that. since there no api nor existing oob stuff on gsa crawl google groups, best way use google adaptor framework , create on own. should easy tbh.
