i have application installed in phones cab drivers use track location , distance traveled cab. (the phone rooted , have privileges on phone). in first implementation of our application used locationmanager.requestlocationupdates location updates gps , network providers. since need capture every kilometer traveled cab enabled "high accuracy" mode in location settings. for 2 reasons willing move fused-location-provider for reason (a known bug in android: https://code.google.com/p/android/issues/detail?id=57707 ) network_provider not providing location updates. for reason devices loses gps fix , not gaining again until device reboots. we observed fusedlocationprovider giving better results , planning change our application use fusedlocationprovider. problem - our devices have older version of googleplayservices not have locationservices. 2 options have are use older version of fusedlocationprovider using locationrequest , locationclient. though giving results out

i'm using this method capture screen in libgdx. of time black screen. when though not capture contents of screen. have few scene2d tables not captured , of elements on screen (like fonts) flipped horizontally. i've tried solutions on internet on screen capturing black screen, or, above method, scarcely result. there chance can capture libgdx screens (loaded shaders) properly?

i have following code: function list() { return "blob1<br>blob2<br>blob3"; } when code run, directly displays whole text in return on call of function. is there way make display blob1 , wait 0.5 seconds, display blob2 , after 0.5 more seconds display blob3 ? this how might it: var stack = ["blob1", "blob2", "blob3"]; function nextitem() { document.body.innerhtml += stack.shift() + "<br>"; } nextitem(); settimeout(nextitem, 500); settimeout(nextitem, 1000);

what know i have custom directive isolate scope. "outside", can communicate to directive using declarative bindings (via @ , = bindings). directive can communicate to outside using either declarative bindings ( = ) or imperative callbacks ( & ). what i'd know is there imperative way communicate to directive ? example say have <edit-profile> directive. i'd expose method reset() , owner of directive can reset directive (imperatively). here's i'd it: <edit-profile on-save="..."></edit-profile> <button ng-click="editprofile.reset()"> reset </button> and here's directive: app.directive("editprofile", function() { return { restrict: "e", scope: { onsave: "&" }, template: ` <input type="text"> <button ng-click="onsave()"> submit </button&g

in program below, trying use mockito junit in test case. don't see how mokito helping create objects test? don't see special here seems if mokito instantiating object. public class testcase1{ @mock myclass myclass; public void setup(){ mokitoannotations.initmoks(this); } @test public void testaddition(){ when(myclass.add(2,2)).thenreturn(20); assertequals(4,myclass.add(2,2)); } } my actual class ( myclass.java ) public class myclass{ public int add(int x, int y){ return x+y; } } is mocking object, same injecting(di) object? appreciate help! your test doesn't test of code. tests mockito works fine. when introduce concept of mocking, take example: suppose build detonator, , want test it. of course use detonator real bomb, , see if whole block explodes when use detonator. isn't practical. btw, maybe don't have bomb @ disposal. maybe c

i'd resolve small quirk i've been having. it's not quirk rather behavior i'd change if possible. if use {n:2} stringformat/converterculture, textbox forced having decimal mark always (even during process of inputting text). mean, can't delete dot or comma @ all, must able figure out have move next "field" of number in order edit decimal points either clicking mouse there or pressing "right". since that's uninituitive users, there way avoid without resorting rewriting formatters? hope simple in framework of existing properties. example, xaml textbox bound datagrid's cell, <textbox name="textbox1" height="18" margin="0,0,10,0" text="{binding selecteditem[1], converterculture=en-us, elementname=grid1, stringformat={}{0:n2}, updatesourcetrigger=propertychanged}" width="59" textalignment="right" verticalalignment="center" /> added remarks after answe

i have issue, working in project git. when feature takes time update develop branch(its kind of gitflow) , later merge changes develop feature branch. it works fine , all. but once done this, history of commits merged , commited feature branch appear there. example: did 2 commits, after updated , merged branches, @ branch history appear first 2 commits , other n commits made other users since merged , commited branch... appear there. how can list commits made me? there way in stash well? and dont know if there way without showing type of file? you can use squash concept merge commits single signature. instance if have 5 commits in dev branch merging them squash show 1 commit in feature branch. git merge --squash

i have map<string,list<string>> (say inputmap) , want convert map<string,list<string>> each (k,v) in new map (v.get(0),k) of inputmap. ex. x -> b,c,d y -> b,d,e z -> b,g,h p -> a,b,d q -> a,d,f r -> a,c,b to b->x,y,z a->p,q,r i thought using like inputmap.entryset().stream().collect(collectors.tomap(map.entry::getvalue.get(0),map.entry::getkey)); and converting map multimap, cannot write map.entry::getvalue.get(0) it great if create multimap in .collect() itself. you can collect directly multimap : multimap<string, string> result = inputmap.entryset().stream() .collect( arraylistmultimap::create, (mm,e) -> mm.put(e.getvalue().get(0), e.getkey()), multimap::putall );

i have defined class complex overloads + operator: complex operator+(complex const& x, complex const& y); i want define implicit conversion double complex , such that, example, if write c + d , c complex , d double , call overloaded + defined above , return complex . how can this? you need define constructor it. referred "converting constructor" complex::complex(double x) { // conversion } this allow implicit conversion, long don't use explicit keyword, force have use cast convert. you can define other versions of operator+ complex operator+(complex const& x, double y); complex operator+(double x, complex const& y);

i have created 2 users, , if create bucket 1 user , object inside bucket can share using http api @ moment.. see here https://simperium.com/docs/reference/http/#objectshare however, when sent through "write_access" = true , 200 result, doesnt seem let me write it. if enable sharing other way allows data sync both ways, doing wrong? has collaboration got further yet? can see there long no docs yet? know? after more trial & error, found solution: to edit shared object, target user (ie user object shared with) needs use objectid equal to: <original_user_simperiumid>/<original_objectid> edit object. if use <original_objectid> won't work. so full command editing shared object, using curl: curl -h 'x-simperium-token: {auth_token_of_target_user}' https://api.simperium.com/1/{appid}/{entity}/i/{original_user_simperiumid>/{original_objectid} -d '{"data_key" : "new_data_value"}'

i'm using text box filter entries. have display updating on text box textchanged event, user isn't hitting enter or pressing button begin filtering. want use autocompletestringcollection remember entries typed text box; however, if save every string text box when textchanged event fired store substrings of each filter term. so instance, if typed string "test" display: "t" "te" "tes" "test" recommended strings. want last string added autocompletestringcollection. i've thought 2 separate methods implement. 1) create task waits "x" amount of time after last textchanged event before adds string autocompletestringcollection. if did have use cancellationtoken cancel task every time textchanged event fired. more complicated because i'm using .net 4.0. 2) search through autocompletestringcollection every time string added , remove substrings (that start @ beginning of word). may backfire if user ty

i called splitshard, , see after posting commit: i thought splitshard supposed rid of original shard, shard1, in case. missing something? expecting 2 remaining shards shard1_0 , shard1_1. the rest call used /admin/collections?collection=default-collection&shard=shard1&action=splitshard if helps. response solr mailing list: once splitshard call completes, marks original shard inactive i.e. no longer accepts requests. yes, have use deleteshard ( https://cwiki.apache.org/confluence/display/solr/collections+api#collectionsapi-api7 ) clean up. as far see on admin ui, information wrong i.e. ui not respect state of shard while displaying them. so, though parent shard might inactive, still end seeing active shard. there's open issue one. one way confirm shard state looking @ shard state in clusterstate.json (or state.json, depending upon version of solr you're using).

i think props , (for example, theme ), universal among components makes sense extract handling (to superclass). follows default value belongs there. however, idionatic way achieve in react? class base extends react.component { bgcolor() { switch (this.props.theme) { case 'summer': return 'yellow'; break; case 'autumn': return 'grey'; break; case 'winter': return 'white'; break; } } } base.defaultprops = { theme: 'autumn' }; class sky extends base { render() { return <div style={{backgroundcolor: this.bgcolor()}}>{this.props.clouds}</div>; } } sky.defaultprops = { clouds: [] }; ... defaultprops class property (as opposed instance ), , there no inheritance. by assigning sky.defaultprops hide base ones. if want combine them, you'd need explicitly that, e.g. sky.defaultprops = object.assign({}, base.defaultprops, { clouds: [] });
