i have following recursive method in class called imagenode passed head( this - start of linked list) class called image. thought code recursively go through each node, increase count when @ end return count, unfortunatly not. going wrong? private int countrec() { int count = 1; imagenode node = this; if (node.next != null ){ node = node.next; count++; countrec(); } return count; } you're ignoring result of countrec() - , you're iterating within recursive call, defeating purpose. (you're making recursive call on same object, no parameters , no change in state... can't good.) recursive approach based on design of: if next node null, size of list 1 otherwise, size 1 + size next node onwards. so: private int countrec() { return next == null ? 1 : 1 + next.countrec(); } now doesn't allow list of length 0 of course... want separate idea of list node, in case list class have like: public int

i integrating facebook login , publish feed in application. , using android simple facebook i implemented login flow, , working on publish flow. want following: when user clicks on share facebook button in app, don't want publish directly want publish permission can publish later (similar instagram, permission @ first , publish when add photo). for have done this: if (msimplefacebook.islogin()) { //the user logged in proceed if (msimplefacebook.getgrantedpermissions().contains( permission.publish_action.getvalue())) { haspermission = true; } else { //we don't have permission request it. msimplefacebook.requestnewpermissions( socialutilities.getfacebookpublishpermissions(), true, newpermissionlistener); } } however if logged in , have session prompted login again before getting permission. have looked in code of simple facebook library , appears logging out , logging in again, , after login req

i have couple of functions in draw method right activated key presses. basically, there's complex grid of squares , each square's color filled in based upon key user presses ('a' makes red, 'b' makes green, etc), method assigned each square. however, each time first key pressed, fill in of squares based upon key (for example, if first key user presses 'a', squares red instead of first one). how make first key pressed applies first method, second key applies second method, , on, when it's in looping draw() method. here's overly-simplified version below: void draw(){ boxone(); boxtwo(); } void boxone(){ if(keypressed){ if(key == 'a'){ fill(red); } if(key == 'b'){ fill(green); } rect(10, 10, 10, 10); } } void boxtwo(){ if(keypressed){ if(key == 'a'){ fill(red); } if(key == 'b'){ fill(green);

i've got passwords on datastore hashed using method securesocialpasswordhasher.passwordhash package securesocial.utils.securesocialpasswordhasher of securesocial , , have validate them through python. therefore, use of securesocial (or whole play framework) out of question. question is: use hashing when calling method? documentation seems bcrypt , wasn't clear enough me sure. ---------edit--------- i've been told on securesocial forums indeed uses bcrypt work factor 10 default. doens't reflect see on datastore. there 2 columns there, 1 salt, , 1 fro hashed password. neither of them have bcrypt header (such $2a$10$ ). also, salt size 11 characters long, , hashed password 22 characters long (and no signs of having salt inside string). found out default hashing passwords on securesocial indeed bcrypt . the default implementation it's hash method is: def hash(plainpassword: string): passwordinfo = { passwordinfo(id, bcrypt.hashp

i'd set proper docker host when running daemon on boot. is there way can pass runtime flags? ideally i'd reproduce: docker -h 0.0.0.0:2375 -d & i've been looking @ same , seems "right" way depends on system using. ubuntu-based systems the official docs explain ubuntu under networking section . update docker_host variable in /etc/default/docker , restart docker daemon. beanstalk docker ami the file in different location: /etc/sysconfig/docker , contains setting other_arg"-r=false" . add options want pass docker daemon @ startup. restarting docker daemon as not familiar internal workings of eb , how docker daemon run, i'd suggest rebooting ec2 instance afterwards. start docker modified settings in appropriate file. i hope helps.

even though objects passed functions means of normal call-by-value parameter passing mechanism, which, in theory, protects , insulates calling argument, still possible side effect occur may affect, or damage, object used argument. example, if object used argument allocates memory , frees memory when destroyed, local copy inside function free same memory when destructor called. leave original object damaged , useless. this written in c++: complete reference in program here #include<iostream> using namespace std; class sample { public: int *ptr; sample(int i) { ptr = new int(i); } ~sample() { cout<<"destroyed"; delete ptr; } void printval() { cout << "the value " << *ptr; } }; void somefunc(sample x) { cout << "say in somefunc " << endl; } int main() {

the windows api provides ways set security descriptors on objects (allowing setup of access control lists , instance). security descriptors of cryptographic keys hosted key storage provider (ksp) can valued using ncryptsetproperty (and proper set of flags , parameters). the cryptography provider development kit (cpdk) doesn't require mandatory support of security descriptors though (and on dedicated servers no user account created, might not useful set access control list indeed). does know if security descriptors support ksp expected microsoft applications despite everything? (like active directory certificate services, instance)

i've seen similar posts, however, no conclusive answers. i using geolite (free database) lookup ip block geo ip, , in bulk- the respective ip's converted ipblocks, , sit table ( l ). every ipblock falls within range (between startipnum , endipnum), sits in table ( g ). the query below works, however, extremely inefficient since need perform on large time period - select l.ipaddress, g.locid l inner join g on l.ipblock between g.startipnum , g.endipnum both tables indexed (g compound indexed), a hash join cannot performed since join made on between operator. is feasible option restructure table g ? or there way? the best index a single query 1 has columns in where / join clause in nodes, , columns in select clause in leaf (if not in node already). try putting index on table l , see if performance improves: create index idx_l_ipblock on l (ipblock) include (ipaddress)

suppose have 1d array = [0...n-1]. define "hole" position in adjacent positions greater it. 1d means [i] < [i-1] < [i+1] (if 0 check i+1 , if n-1 check n-2). divide , conquer method solve in 1d case, or in case of square matrix? in square matrix, (0,0) hole if it's less (0,1) , (1,0) (so corners corners). i feel understand divide , conquer, when comes applying problems stumped. asked 1d question in interview , failed solve it. interviewer told me 2d square case challenging extension practice (that hardly able solve in full). i'm happy psuedocode, want idea of what's going on.

i use antlr parse programming language. according antlr book (chapter 9.4) implemented "error alternatives". easy implementation described in book notifying error listener: ..... | id '{' expr '}' '}' {notifyerrorlisteners("too many braces");} ..... after reading book thought easier implement notifications listeners wrote in baselistener: public void exitexprerror(@notnull myparser.exprerrorcontext ctx) { parser.notifyerrorlisteners(ctx.start, "too many braces", null); } in listener can extract start , stop token context gives me finer grained control mark error (ctx.start). however listener in grammar file simplier , faster implement listener. my question is: is possible add arguments listener in grammar file? something like: ..... | id '{' expr '}' '}' {notifyerrorlisteners(ctx.start,"too many braces");} .....

the main difference between built-in data types , user defined data types that: built-in data types can accept literal values(values inserted code directly,this process know hard-codding). so possible create custom data type same boolean accepts 3 values: yes/no/maybe without using enums. such following code: mycustomboolean = maybe; i asked above question because want understand built-in data types in c# instructed in core language(such c++ int,char...) or no? ---update--- for second question,let me ask question make 2nd question more clear: i know example string alias of system.string pure string in c# works without system.string? there no ways you've requested. can create constant fields in c# can accomplish result (named values) integral types or strings - in other words, things can use compile-time constants. can particularly useful otherwise magic values . public const string maybe = "maybe"; public const int maybe = 0; one way aroun

this first project using bootstrap , i'm pretty new jquery also, hope question not simple of you. have drop-down have created pulling data sharepoint using rest , ajax. part works great. js: $(document).ready(function () { var requesturi = "blah-blah/_api/web/lists/getbytitle('ad_db')/items?select=title,state"; var requestheaders = { "accept": "application/json;odata=verbose" } $.ajax({ url: requesturi, type: 'get', datatype: 'json', async: false, headers: requestheaders, success: function (data) { $.each(data.d.results, function (i, result) { var itemcasenumber = result.title; var itemstate = result.state; $('#mylist').append('<li role="presentation"><a role="menuitem" tabindex="-1" href="#">' + itemcasenumber + '</a></li>'); }); }, error: functi
