in recent conversation fellow programmer, asserted "if you're writing same code more once, it's idea refactor functionality such can called once each of places." my fellow programmer buddy instead insisted performance impact of making these function calls not acceptable. now, i'm not looking validation of right. i'm curious know if there situations or patterns should consider performance impact of function call before refactoring. "my fellow programmer buddy instead insisted performance impact of making these function calls not acceptable." ...to proper answer " prove it. " the old saw premature optimization applies here. isn't familiar needs educated before more harm. imho, if don't have attitude you'd rather spend couple hours writing routine can used both 10 seconds cutting , pasting code, don't deserve call coder.

i've been working weka couple of months now. currently, i'm working on machine learning course here in ostfold university college. need better way construct decision tree based on separated training , test sets. come idea can of great relief. thanx in advance. -neo you might asking more specific, in general: you build decision tree training set, , evaluate performance of tree using test set. in other words, on test data, call function named c*lassify*, passing in newly-built tree , data point (within test set) wish classify. this function returns leaf (terminal) node tree data point belongs--and assuming contents of leaf homogeneous (populated data single class, not mixture) have in essence assigned class label data point. when compare class label assigned tree data point's actual class label, , repeat instances in test set, have metric evaluate performance of tree. a rule of thumb: shuffle data, assign 90% training set , other 10% test set.

for project company i'm working on setting up, in need of auditing (storing logs) various of tasks (changes made tables in system) users perform. currently, there 3 different types of tasks. may grow in future. my suggestion following schema table's , relationships (example): table auditlog ------------------------------ id | pk description created and every task: table exampletaskauditlog ------------------------------ exampletaskid | fk pk auditlogid | fk pk and: table anotherexampletaskauditlog ------------------------------ anotherexampletaskid | fk pk auditlogid | fk pk basically, every kind of task need audit, have new table holding relationship. what developer suggested, following: table auditlog ------------------------------ id (pk) description created exampletaskid | nullable anotherexampletaskid | nullable type | (an integer id indicates whether "example task" or "another example task"). basically, if create log "examp...

std::hash_map not part of c++ standard part of extensions standard library. example defined vs2005 . std::hash_map.erase invalidate iterators std::hash_map ? presumably, memory can reallocated smaller array when elements removed optimize memory usage. so hash_map.erase invalidate iterators? it looks specified in vs2005 example in documentation: each element contains separate key , mapped value. sequence represented in way permits lookup, insertion, , removal of arbitrary element number of operations independent of number of elements in sequence (constant time) -- @ least in best of cases. moreover, inserting element invalidates no iterators, , removing element invalidates iterators point @ removed element.

i have job postings board i'm running in php/mysql , thinking of trying run in yql , google docs instead. have line of mysql fetches job postings have been posted in last 60 days only: $sql = "select * `job` curdate( ) <= date_add( `postdate` , interval 60 day ) order `postdate` desc;"; is there yql equivalent of this? (the format of timestamp column in spreadsheet of form submissions in google docs is: 2/11/2011 10:23:37 yql doesn't have option of custom functions within queries, curdate() , date_add() , etc. out of question. however, there no reason why not craft queries like: select * job postdate > $date order postdate desc; where $date integer timestamp (if available in google doc?). or, select * job interval = 60; this latter query need bespoke data table interpret query parameter(s) , format query against google doc. advantage of crafting own table able use javascript (in <execute> block) perform server-side processi...

it's small annoying issue. i'm using navigation controller , not rotate. using code before without navigation controller , rotating beautifully. isn't calling "-(bool)shouldautororatetointerfaceorientation..." i'm @ bit of loss. thanks in advance. edit: , yes have "-(bool)canbecomefirstresponder" set. edit2: have calling "-(bool)shouldautororatetointerfaceorientation..." when app first runs , @ point screen rotated when shows navcontroller sets portrait mode... there's problem uiwindow propagating these events view controllers other root one. if you're adding controller directly uiwindow , isn't first 1 you've added, add root view instead. otherwise, you'll need take @ implementing own rotation transformations. i've got uiviewcontroller subclass heavy lifting on github here .

i have 2 classes implement isomebehavior. want them share functionality. replace isomebehavior abstract class, somebehaviorbase. problem 1 of subclasses derives class, , other class isn’t software own. (this c#, multiple inheritance isn't option.) subclass, derives 3rd party class, has no implementation. derives 3rd party class, , implements isomebehavior, 3rd party class can treated same way other subclasses implement isomebehavior. what i've done, moment, implement extension method on isomebehavior. consuming code can call method. problem approach want force calling code use extension method. can't remove somemethod() interface, because extension method has call it. any ideas on how let 2 classes elegantly share same behavior, when 1 of them derives another, third party, class? note: strategy design pattern sounds makes sense here, pattern used when behavior varies among subclasses. behavior here doesn't vary; needs shared. is there reason can't...

after adding resource, database file in project root. i've been able open specifying full path os x sees it, i.e., "/users/louis/documents/test project/test.db". but of course there no such path on iphone. i think should define path "application root/test.db" don't know how, or if work anywhere else besides development machine. thanks ideas. to path of file you've added in xcode use pathforresource:oftype: mainbundle. nsstring *path = [[nsbundle mainbundle] pathforresource:@"yourdb" oftype:@"sqlite"]; but can't change files in mainbundle. have copy location. example library of app. you this: nsstring *librarypath = [nssearchpathfordirectoriesindomains(nslibrarydirectory, nsuserdomainmask, yes) lastobject]; nsstring *targetpath = [librarypath stringbyappendingpathcomponent:@"yourdb.sqlite"]; if (![[nsfilemanager defaultmanager] fileexistsatpath:targetpath]) { // database doesn't exist...

i need ascender / descender , x-height .. by using following code can find descender , total height: descender_height = paint.descent(); total_height = descender_height - paint.ascent(); //ascender = ?; equal descender height? //x_height = ?; total_height - 2*descender_height ? thanks i think ascender , descender height typically same, wouldn't depend on every font. don't see direct way x-height, trick use below. also, total height, talking absolute distance highest ascender lowest descender? i've included below. haven't tested these myself, should work (but let me know if i'm misinterpreting you've said): // assuming textpaint/paint tp; rect bounds; // retrieve bounding rect 'x' tp.gettextbounds("x", 0, 1, bounds); int xheight = bounds.height(); paint.fontmetrics metrics = tp.getfontmetrics(); int totalheight = metrics.top - metrics.bottom;

i'm not sure converttoworldspace works. i have spritea parent. i set position 40,40 example , add scene. i have second spriteb set @ position 80,80. i add spriteb spritea. i print out position of spriteb: 80,80. i print [self converttoworldspace:spriteb.position]. and, still 80,80. shouldn't spriteb position different here? in case if want know position of spriteb in current world must call "converttoworldspace" methods parent (the spritea) : [spritea converttoworldspace:spriteb.position]; the "converttoworldspace:" method applies node's transformation given position. should call methods parent's sprite.
