i'd have single maven build produce artifact can used on local machine, our dev environment, staging environment, or production. since we're talking production, means db credentials can't in artifact anywhere. this spring app we're using maven resource filtering , profiles ( local , dev , stage , prod ) filter properties in application.properties file , other files (email templates, etc). have build separate artifact each environment. we have been able db passwords out of pom using @propertysource annotation still seems we're missing must common problem. i've been able find similar questions answers seem have problem or 2 - common of having sensitive properties production in artifact.

i'm measuring performance of various components of app , i'd statistics using locust load testing framework. currently, there's way measure average response time using built-in locust method . is possible statistics on custom parameter (which part of server response) , add reports without forking locust? perhaps monkey-patching options available?

i looking solution problem on stackoverflow since couldn't find accurate solution ended solving myself , post here, hope help. google maps provides polyline feature, based on list of coordinates can draw series of lines joining of them. you can draw polyline single arrow following code: var allcoordinates = [ new google.maps.latlng(26.291, 148.027), new google.maps.latlng(26.291, 150.027), new google.maps.latlng(22.291, 153.027), new google.maps.latlng(18.291, 153.027) ]; var polyline = new google.maps.polyline({ path: allcoordinates, strokecolor: color, strokeopacity: 1.0, strokeweight: 2, geodesic: true, icons: [{ icon: {path: google.maps.symbolpath.forward_closed_arrow}, offset: '100%' }] }); the problem here arrow drawn in last segment shown in next picture, route not straightforward , need...

i'm updating old, large piece of software written in c sends struct through socket server. updated software written in python, means need send same information in same byte layout c struct in python. i'm aware of python package struct, , use it. problem is, struct absolutely huge. give idea, here's snipet: // struct wish send typedef struct { struct st_command_header header; union { char buffer[32]; struct set_360_camera_message camera_msg; struct u_olcd_msg olcd_msg; }; } struct_to_be_set stc; // supporting structs struct st_command_header { union u_all_types len; union u_all_types cmd; union u_all_types cmd_counter; union u_all_types items; } __attribute__((packed)); struct u_olcd_msg { // on 100 lines of fields fill } // other structs necessary as understand it, struct python package requires manually pack struct, difficult given size of struct , number of union statements. ideally, i'd way u...

my question how store data once received online , still can processed after mobile device got offline and/or restarted. i'm using angularjs ionic (phonegap) building apps. question not explicitly adressing these technologies. best practices, patterns or algorythms helpful me or useful articles or key words. 1) simple challenge make app more user-friendly making functionality usable not if device online in offline mode. in case implies have make last fetched online data available later use (while device offline , after restarting device!). 2) bit more difficult reduce communication costs synchronizing server side changed data when device reconnects internet. 3) entities can produced on client side while device offline , must synchronized server too. there no potential risks of conflicts because users don't share entities write access. 4) use googles , apples push services inform devices newer entity versions, should updated on client side. polling isn't neede...

suppose had basic moving average function keeping track of sum. example: queue values; double sum; double calcsma(double next) { values.push(next); sum -= values.pop(); sum += next; return sum / sma_length; } one example of how break down if our window 5 wide fed like: 2, 2, 2, 2, 2, 2, 2, 1e100, 2, 2, 2, 2, 2, 2, 2, 2 . output 2, 2, 2, 2e99, 2e99, 2e99, 2e99, 2e99, 0, 0, 0 . even if sum isn't quite dramatically off, there still quite reasonable instances small loss in precision make sum artificially increase tiny amount. on long period of time, add , become issue. does have ideas of how work around loss in precision? edit: note function designed work o(1). necessary. so, recalculating each time won't work: window large. you recalculate fresh sum on every sma_length values stop errors accumulating: queue values; double sum = 0.0; double freshsum = 0.0; int count = 0; double calcsma(double next) { values.push(next); sum -= value...

i have a datagridview in have a datagridviewcomboboxcolumn as 1 of column. this column's columntype = datagridviewcomboboxcolumn. in combo box have items admin,user,animal,human , birds. first item displayed when grid view loads admin (notice lowercase letter.). everything working fine problem arises - whenever user changing name admin admin/admin/admin etc. , clicking anywhere else in gridview column again showing admin in column when same scenario done time user presses enter or tab button , value changed. i not understanding why happened? what difference between click , enter/tab combo box? one more thing if user typing other word except "admin" , value changed on click. i think problem arises when typing uppercase letter or mixture of upper , lower case letters. same thing happened other items of combo box such animal/birds etc.

i totally exhausted @ drag , drop components in inspector. what want find every object have component had chosen t void getallgameobjectwhichhave<t>(ref int cnt, gameobject[] f_array, gameobject transformforsearch) { foreach (transform trans in transformforsearch.transform) { getallgameobjectwhichhave<t>(ref cnt, f_array, trans.gameobject); t temp = trans.gameobject.getcomponent<t>(); if (temp != null && cnt < f_array.length) { f_array[cnt++] = trans.gameobject; } } } and used this //onawake() getallgameobjectwhichhave<rigidbody2d>(ref zeroint, enougharray, tophierarchyobj); this recursive function gets every gameobject , save them @ f_array. cannot filter , 'temp' not null. t temp = trans.gameobject.getcomponent() doesn't seem working meant. did misunderstand something? just use findobjectsoftype<t>() . (yep, generic variant exists) array ...

i use c++ rtti. have type_info of class. how can tell whether class subclass of first one, if have type_info ? #include <typeinfo> class foo { public: virtual ~foo() {} }; class boo: public foo { public: virtual ~boo() {} }; class bar { public: virtual ~bar() {} }; template<class t> bool instanceof(const type_info& info) { // answer comes here!! } int main(int argc, const char* argv[]) { const type_info& fooinfo = typeid(foo); const type_info& barinfo = typeid(bar); bool booisfoo = instanceof<boo>(fooinfo); // should true bool booisbar = instanceof<boo>(barinfo); // should false return 0; } if have 2 typeinfo , b. there no general way determine if subclass of b. you may: store information (static structure filled @ runtime?) make educated guesses using type name (i.e. parsing type info string , name types accordingly). previous answers. require instantiate type somehow: type_info no...
