i building website need retrieve facebook shares , likes of numerous links , urls different sites. the problem is, urls impossible wanted. example, when data links http://www.example.com/?a=1&b=2&c=3 wrong data http://www.example.com/?a=1 , rest of url ( &b=2&c=3 ) ignored facebook. here @ stackoverflow, lot of people looking answer , many questions unanswered. so, once did right, i'm tell how did it. p.s. : works non-facebook urls. if you're looking shares , likes counts of internal facebook link (image, video ...), won't work you. i'll using php answer question. to likes , shares counts, use fql instead of graph api (even though using graph api send query). but not enough : able so, had call rawurlencode() function on url want data about. otherwise, i'll keep getting errors. so, likes() , function using have counts : function likes($url) { $url = rawurlencode($url); $json_string = file_get_contents("http://

i'm running small number of game servers (one per cpu core). despite hardware quite powerful , no other tasks running on cores, i'm facing problems related stability of frames per second indicator. causes game server processes waiting long (sometimes 3-4 ms, unacceptable in case). strace utility shows like: 17:56:27.683580 gettimeofday({1374414987, 683587}, null) = 0 <0.000003> 17:56:27.683599 gettimeofday({1374414987, 683606}, null) = 0 <0.000003> 17:56:27.683619 gettimeofday({1374414987, 683626}, null) = 0 <0.001693> 17:56:27.685387 gettimeofday({1374414987, 685437}, null) = 0 <0.000034> 17:56:27.685492 gettimeofday({1374414987, 685550}, null) = 0 <0.000025> perhaps reason why lags (taking account gameserver process single-threaded) happen. however, question why of system calls take time? i've tried kernels various types of kernel preemtion, result still same. looking forward help. p.s. os - debian 7 64 bit linux kernel ver

when try create thread this somefunc(void* param){ char currfile[500000]; char currkeyboard[24576]; char currimage[500000]; char curraddinfo[12000]; } _beginthread( somefunc, 0,null ); the program crash whith stackoverflow exception.but when this somefunc(void* param){ char currfile[500000]; char currkeyboard[24576]; char currimage[500000]; } _beginthread( somefunc, 0,null ); the program don`t crash.why? the reason second function allocates less memory on stack first. way stuff allocate. use vectors instead, they'll allocate on heap, , since manage own memory won't have to.

i orderby evaluate expression currently have: ng_repeat: "post in posts | orderby:"up_votes" i instead order {{up_votes - down_votes}} ng_repeat: "post in posts | orderby:'down_votes - up_votes'" just use single quotes wrap expression orderby or add votediff function controller , orderby:votediff

i'm starting lua scripting , seem stuck @ simple problem. i'm trying implement floyd-warschall algorithm compute shortest paths between each vertices of graph ( http://en.wikipedia.org/wiki/floyd –warshall_algorithm short explanation of algorithm). written in python (here's code https://gist.github.com/davidcain/4032399 ). version little different, in order make fit main code, same thing. here's commented code. every time run it, "attempt index field '?' (a nil value)" (i feel solution simple enough, can't seem put finger on it. appreciated): function adj(bodies) --returns, 1d array of vertices called "bodies", square adjacency matrix (a matrix of size number_of_vertices x number_of_vertices tells, ones, if vertices connected, or 'infs' if not connected) n = table.getn(bodies) dist = {} _,i in pairs(bodies) dist[i] = {} _,j in pairs(bodies) if == j dist[i][j] = 0

how align 2 text elements, 1 left , other right, on same line. i'm aware can done using floats float less solution. i'm looking way using display:inline . html: <div class="contailner"> <div class="inlineleft">item 1</div> <div class="inlineright">item 2</div> </div> css: .container { width: 600px; border: 1px solid blue; } .inlineleft, .inlineright { display: inline; } .inlineright { ...align right... } you use position:absolute on inline elements , position:relative on container. can align inline elements way want relative container. this: .container { position: relative; width: 600px; border: 1px solid blue; } .inlineleft, .inlineright { position: absolute; display: inline; } .inlineright { right: 0; } demo

i have app 2 activities. main activity start secondary activity using startactivityforresult() . secondary activity returns data (in form of intent object) main activity. on main activity have method onactivityresult() handle come secondary activity. within onactivityresult() method, need update view on main activity (to reflect new data values). not explicitly spawn threads. question is: can directly modify view within onactivityresult() method, or need put event on ui queue it? more explicit: can sure onactivityresult() method on ui thread, , in case can forget ui queue? yes, can modify view in onactivityresult() . can modify activity 's views anytime after call setcontentview() in oncreate() , long running on ui thread. yes, onactivityresult() called on ui thread. true life cycle methods ( oncreate() , onresume() , etc).

i searched on internet implementation in converting not numbers expressions variable expressions infix notation prefix , postfix. searches did weren't successful. want see if there implementation yet in php modify support more operators not (-,*,+,=). for example convert: a+b/c*(p/c) while keeping variable names, , not having enter numbers evaluate them. i have found implementation in evalmath class provided miles kaufmann here : http://www.phpclasses.org/package/2695-php-safely-evaluate-mathematical-expressions.html infix postfix code : // convert infix postfix notation function nfx($expr) { $index = 0; $stack = new evalmathstack; $output = array(); // postfix form of expression, passed pfx() $expr = trim(strtolower($expr)); $ops = array('+', '-', '*', '/', '^', '_'); $ops_r = array('+'=>0,'-'=>0,'*'=>0,'/'=>0,&

i've got handlebars template displaying list of articles. each article has 2 prompts associated through belongsto relationship. information correctly coming server json: {"article":[{"id":7,"prompt_one":{"content":"thing1"},"prompt_two":{"content":"thing2"}]} now i'm able render other data article okay, haven't been able data 1 of prompts render in handlebars template. thought simple as: <p>{{prompt_one.content}}</p> but nothing shows , no errors displayed. what's proper way render associated models content? you can 2 things: embedded records. if prompt objects embedded article's json need define them embedded ( ember-data not support embedded objects ). ds.restadapter.map('app.article',{ prompt:{ embedded:'always' } }) app.article = ds.model.extend({ prompt: ds.belongsto(app.prompt,{embedded:'always'}), }

ok, know can limit size of characters of table field while fetching, of times split comes in middle of word: select id, title, left(contents, 300) contents posts now, possible make split come after word (at space)? thank you if using sql server, can like: select id, title, left(contents, (case when charindex(contents, ' ', 300) > 0 charindex(contents, ' ', 300) else 300 end) ) contents posts; in mysql: select id, title, left(contents, (case when locate(' ', contents, 300) > 0 locate(' ', contents, 300) else 300 end) ) contents posts; other databases have similar functions.

i have structure this, string[] variable1= new string["abc", "fss" , "fsfs", "gdgdds"]; string[] variable2= new string["sa", "gs" , "qe", "hf"]; static list<string[]> alllist = new list<string[]>();; alllist .add(variable1); alllist .add(variable2); when string provided want search alllist , provide result array if found . any archiving in efficient way? both provided solutions run in linear time, way slow if have lots of words , make lots of queries. you can use dictionary. dictionary uses hash table internally , much, faster. to put strings in dictionary, can do: dictionary<string, string[]> dict = new dictionary<string, string[]>(); foreach(string[] arr in alllist) foreach(string str in arr) dict[str] = arr; and can search it: string s = "abc"; if(dict.containskey(s)) // result dict[s] else // string not in array h

in application, using xml mapping metadata alternative annotation. worked fine jpa annotations far. auditing, using hibernate envers. declaring @audited @audittable("loan_applicant_audit") problem how put these annotations in xml mapping metadata form. there requirement user should specify list of tables, needs audited. plus should able configure name of audit tables according needs. last step particular column names inside table needs audited should configurable. currently that's not possible. envers works annotating pojos only. there jira ticket enable xml config, doesn't feature come anytime soon: https://hibernate.atlassian.net/browse/hhh-3887 anyway, if want use envers, you'll have go annotations.

can explain java when _java_options environment variable defined & when application launched on windows machine? you can use _java_options pass default options any jvm process started on system. for example, set _java_options=-dsun.java2d.noddraw=true when jvm starts, parses value of _java_options if parameters @ command line of java. can see passed parameters via jvisualvm. for more information, read blog post: what discovered while trying pass default jvm parameters

in ruby api, examples has_many associations example: firm class declares has_many :clients, add: firm#clients (similar clients.find :all, :conditions => ["firm_id = ?", id]) firm#clients<< firm#clients.delete firm#clients= firm#client_ids why arn't methods firm.clients, firm.clients<< etc.. # sign mean? if written firm.clients , mean it's method call on firm , not on instances of it. if there particular instance firm on want call method, can write firm.clients . 1 purpose of api show methods available on instance of class. firm#clients means method call of clients on arbitrary instance of firm . # used in way not part of ruby syntax, established convention.

i have issue , need help. have realtime graph vertical bar moves cursor , want show value of graph (d.time , d.value) when cursor points to. http://jsfiddle.net/qbdgb/54/ have 2 series of data (data1s , data2s) generated randomly , put time in data generated in "time" variable can see: now = new date(date.now() - duration); var data1 = initialise(); var data2 = initialise(); //make stacked data var data1s = data1; var data2s = []; for(var = 0; < data1s.length; i++){ data2s.push({ value: data1s[i].value + data2[i].value, time: data2[i].time } )}; function initialise() { var arr = []; (var = 0; < n; i++) { var obj = { time: date.now(), value: math.floor(math.random() * 100) }; arr.push(obj); } return arr; } when hover around graph want tooltip show time , value not recognize , show "undefined" since not know how pass datasets (data1s , data2s) "mouseover function can recognize data show! how tooltip functions made , c

here's fiddle . can see i've defined simple click event handler: $('#traveller > a').click(function(e) { e.preventdefault(); var $ul = $('#traveller ul'); if($(this).hasclass('handle-next')) { if(math.abs($ul.position().top - parentpadding) < totalheight - itemheight) { $ul.animate({top: '-=' + itemheight}); } } else { if($ul.position().top - parentpadding < 0) { $ul.animate({top: '+=' + itemheight}); } } }); i've noticed when make few double clicks quickly, pressing a.handle-next / a.handle-prev , ul position changes unexpectedly. howcome avoid behavior? just check if $ul animated: if($ul.is(':animated')) return; demo

i find out differences in drawcontour behaviour between windows , linux : following code prints filled contour on windows expect : drawcontours( imin, contours, -1, color, cv_filled, 8 ); however on linux, contour drawn not filled. not using same version of opencv ( 2.4.5 on windows, 2.4.0 on linux), has seen similar ? thank you. actually, list of points in countours differents : repeated 1 time (why don't know). same inputs, drawcontours results indeed same.

i'm analyzing few vb.net applications connect mysql database, since i'm not person programmed them, there few doubts in analysis in terms of when db connection opened or closed. by looking @ administration panel mysql appears not opened connections closed i'd know if there tool capable of analyzing source-code , detect when connection opened , if/when it's closed. does know of such tool?

i've data processing algorithm apply 1 of android application. algorithm can implemented via java or native code c. safer algorithm implementation java or c far know android dex file can reversed engineered. applicable c? code safety maximum when in c(native) java. "so far know android dex file can reversed engineered. applicable c?" doing in java by making code-pakages library can make java codes safe. if reverse engineerd or apk breaked code not visible, encrypted format. change algorithm package library , add project assets folder , buildpath. doing in c and if doing in c sure 1 breaks apk cant see c code. sometime visible not in readble format. if implementing via c, make process more faster in java , allocated more memory process. heap memory not limitation code. thing is, because of using jni chances of getting errors more , difficult trackdown errors in runtime. note :since hacking can done in many ways.. cant give compleate assuranc
