i going use google play services in android application. have no problem there, have theoretical question... in google docs api says must import project source sdk, , not *.jar file lib ( google play services setup docs ). this fine, find more natural add reference *.jar file in there. my question therefore is: there reason google says must this? if not i'd rather reference *.jar file. thanks, jason google play service contains resources (layout, images, etc.) cannot included in jar file. linked way framework compute xml resources of project give them unique ids. this why have import library project instead of including jar dependency.

i have found strange bug in ios. when use uinavigationcontroller , push other controllers, titleview shifted right how many controllers pushed it's looks this: my code simple: self.navigationitem.title = @"test title"; in second case, controller has 5th in viewcontrollers stack. controller in cases same. i using appearance uibarbuttonitem , in appdelegate. [[uibarbuttonitem appearance] setbackbuttontitlepositionadjustment:uioffsetmake(-1000, 0) forbarmetrics:uibarmetricsdefault]; i fix trick =) [[uibarbuttonitem appearancewhencontainedin:[uinavigationbar class], nil] settitletextattributes:@{uitextattributefont: [uifont systemfontofsize:0.1]} forstate:uicontrolstatenormal];

i'm using jeuclid library rendering mathml script. want display data tables using mathml . i googled results describe mtable examples showing describing matrices. so, i'm puzzled whether possible. in our current framework, it's not possible use other resources except graphics object of jpanel or mathml script. so, please point me in right direction. links examples highly appreciated. mtable not matrices (in particular not add parenthesis around data) used vertical alignment layouts such tables , aligned equations.

i making pacman game , working on ghosts ai. planning on using dijkstra's algorithm pathfinding. problem when game loaded vertexes graph stored in matrix. trying assign each vertex of edges this for(int x = 0; x<40; x++) { for(int y = 0; y<40; y++) { vertex vertex = map[x][y]; vertex.adjacencies = new edge[]{new edge(map[x-1][y], 1), new edge(map[x+1][y], 1), new edge(map[x][y-1], 1), new edge(map[x][y+1], 1)}; } } the problem throws array out of bounds exception. how fix without putting in tons of if statements check if current vertex on edge of graph. one easy way include non-traversable border around edges. for example, if actual map 40x40, can declare 42x42 array. rows 0 , n non-traversable, columns 0 , n. you'd still need handle cylindrical travel of pacman between left , right sides.

the whole idea authenticate app , app lite , app iphone , app iphone lite single box.com app id , return user right app redirected user authorization/authentication web site. my conclusion till leads using different app id, because of lack of option add different redirect url's , respectively possibility [box-api] recognize right caller application. will work if try embed auth url in uiwebview , handle response webview? we don't support use case, , you'll need separate app ids

this question has answer here: in python, why can function modify arguments perceived caller, not others? 8 answers here 2 methods. 1 modifies variable x, other not. can please explain me why is? x = [1,2,3,4] def switch(a,b,x): x[a], x[b] = x[b], x[a] switch(0,1,x) print(x) [2,1,3,4] def swatch(x): x = [0,0,0,0] swatch(x) print(x) [2,1,3,4] the function definition def swatch(x): defines x local variable. x = [0, 0, 0, 0] reassigns local variable x new list. not affect global variable x of same name. you remove x arguments of swatch : def swatch(): x = [0, 0, 0, 0] but when python encounters assignment inside function definition like x = [0, 0, 0, 0] python consider x local variable default. assigning values x not affect global variable, x . to tell python wish x global variable, need use global declaration:

how jquery text() preserve blanks? want $("#ele").text("a a"); to show spaces in between. i have created jsfiddle illustrate problem. http://jsfiddle.net/zx4x9/ .html() works, i'd have convert other entities first ( <, >, " etc.). and, seems text() should able this. the problem not .text() . if want consecutive , other stray spaces show up, can use white-space: pre <li> s: ul li { white-space: pre; } see this

i'm learning c , sense how faster of c code python equivalent. i'm running ubuntu 12.04 from command line can use "time" command. give execution time of program in 3 separate mode (by default) - a. real time; b. user time; c. system time. a. real time indicates how time took overall; b. user time indicates how time took executing @ userspace c. system time indicates how time took executing @ kernel space. above way measure time commnad line. can measure program execution time in program - using system call gettimeofday().

hi guys iam new here.i able detect hand , finger tips using opencv.. iam stuck in getting center of palm of hand..need guidance.. thanx in advance. you gap between middle finger , ring finger. than, assuming know inclination of hand (if not should method determine it, example tracing line between index finger , medium finger gap between middle finger , little finger), trace line perpendicular hand's inclination. gap between thumb , index , trace line parallel hand's inclination. intersection between 2 lines reasonably near center of hand.

we delve infinite series in calculus , being said, i'm having fun it. derived own inverse tan infinte series in python , set 1 pi/4*4 pi. know it's not fastest algorithm, please let's not discuss algorithm. discuss how represent very small numbers in python. notice programs iterate series, stops somewhere @ 20 decimal places (give or take). tried using decimal module , pushed 509. want infinite (almost) representation. is there way such thing? reckon no data type able handle such immensity, if can show me way around that, appreciate much. python's decimal module requires specify "context," affects how precise representation be. i might recommend gmpy2 type of thing - can calculation on rational numbers (arbitrary precision) , convert decimal @ last step. here's example - substitute own algorithm needed: import gmpy2 # see https://gmpy2.readthedocs.org/en/latest/mpfr.html gmpy2.get_context().precision = 10000 pi = 0 n in range(10000

after finish developing app using google app engine, how easy distribute if ever need without app engine? thing i've thought of gae has proprietary api using datastore. so, if need deliver app .war file (for example) not deployed app engine, need first refactor code getting/storing data, before building .war, right? i don't know standard way deliver finished web app product - i've ever used gae, i'm starting project requirements final deliverables unsure @ time. so i'm wondering, if develop gae, how easy convert? also, there can or consider while writing gae optimize project whatever packaging options may have in end? so long app not have elements dependent of google app engines should able deploy anywhere long location can support tomcat or glassfish server. requires manually install server must read on that. there lots of youtubes on subject try break down issue lowest steps possible. i suggest using framework spring , hibernate lessen headac

some details first: i have 4 image place holders. have several checkboxes. each checkbox associated image. user allowed check off 4 boxes. when user clicks on checkbox replaces 1 of image place holders image assoicated checkbox. after user checks off 4 of check boxes, rest of chexkboxes become disabled. so have 4 image place holders populated images checked check boxes. here issue comes play. if user decides uncheck box, need correct place holder image go it's generic place holder image. so if 4 checkboxes user checked 1: hammer 2: screwdriver 3: nails 4: saw. 4 place holder images populated hammer, screwdrive, nails , saw. if decide uncheck screwdriver checkbox placeholder image screwdrive should switch generic place holder image. i'm having hard time figuring out how that. thanks in advance! function countchecked() { var radiocandycount = document.getelementsbyname('howmanycandies'); (var = 0, length = radiocandycount.leng

i have following string: [a] [abc] test [zzzz] i'm trying array so: [0] => [1] => abc [2] => zzzz i've tried following code: var string = '[a] [abc] test [zzzz]'; var matches = string.match(/\[(.*?)\]/g); for(var = 0; < matches.length; i++) console.log(matches[i]); but console output shows: [a] [abc] [zzzz] i tried adding 2 non-capturing groups ( ?: ), so: var matches = string.match(/(?:\[)(.*?)(?:\])/g); but see same matches, unchanged. what's going wrong, , how can array want? match doesn't capture groups in global matches. made little helper purpose. string.prototype.gmatch = function(regex) { var result = []; this.replace(regex, function() { var matches = [].slice.call(arguments,1,-2); result.push.apply(result, matches); }); return result; }; and use like: var matches = string.gmatch(/\[(.*?)\])/g);

i need load different functions different ajaxsuccess in 1 page. i have multiple ajax in 1 page , cannot figure away more specific on ajaxsuccess happen. at moment using: $(document).ajaxsuccess(function(){ func1(); }); // ajax1 success => load func1() // ajax 2 success => load func2() // ajax 3 success => load func3() you can attach separate successs methods each call using $.ajax({ type : "post", url : "url", data:"{}", contenttype : "application/json; charset=utf-8;", datatype: "json", success : function(response){}, error : function(response){} }); using approach can call specific success method attached each ajax call. don't need bind every call 1 common ajaxsuccess. , if want so, need send kind of id in response call specific function. e.g $(document).ajaxsuccess(function(response){ if (response.id==1) func1(); else if (response.id==2)

i have 40 categories , each category has 10-100 subcategories. default, user listens categories , subcategories. want give each user ablity select unbind whole category or specific subcategory. so, right have each category channel, , each subcategory event. now, have each user bound 2000-3000 events, , know wrong, right way let user filter between 3000 events? okay bind many events? it's important remember when subscribe channel events channel sent client (pusher - clients), if have not bound event. with information above in mind, i'd recommend using channels filter data. overhead when subscribing channels isn't great. example, subscribing 40 channels wouldn't represent significant resource usage. need consider if channels public (anybody can subscribe) or private each call pusher.subscribe( 'private-channel-x' ); result in authentication request server. there multi-auth plugin allows batching of authentication requests take place. one sol

i found interesting case while testing string creation , checking hashcode. in first case created string using copy constructor: public class test { /** * @param args */ public static void main(string[] args) { string s1 = new string("myteststring"); string s3 = s1.intern(); system.out.println("s1: " + system.identityhashcode(s1) + " s3:" + system.identityhashcode(s3)); } } output of above code is: s1: 816115710 s3:478684581 this expected output interned string picks reference string pool whereas s1 picks reference of new object. identity hash code different. now if create string using char array see strange behavior: public class test { /** * @param args */ public static void main(string[] args) { char[] c1 = { 'm', 'y', 't', 'e', 's', 't', 's', 't', 'r', 'i'
