i made topic on before , got closed , labeled off-topic. tried reading faqs couldn't figure out why pardon me if off-topic had additional questions on issue. i have field contains full name in following format: first, last (mi.) challenges: the middle initial isn't present entries don't have middle initial listed. some middle initials have period @ end. many of names spanish names can have multiple first , last names splitting field space isn't option. the name field may have white spaces @ end. the middle name may contain accented character (i couldn't find spanish middle names did start accent couldn't sure wouldn't have any). what i've done far: the first thing did used trim() remove padding @ end of field. fname.trim() next, i've split name first , last names following: string[] names = fname.split(","); i need split middle name last name, can following: fname = names[0] + " " names [1] + " ...

im using intellij idea 12. can customise code generated using "refactor" functional? for example want change template of setting generation(encapsulate fields) from: public void setfield(string field) { this.field = field; } to public myclass setfield(string field) { this.field = field; return this; } as far know, can't you're suggesting in intellij. there plugins , however, can generation of fluent interfaces.

i'm using drupal bootsrap base theme , i'm building sub theme on top of it. site default 1170 px wide middle of content on same page have browser full width content (max 1400px). since drupal bootsrap theme has container s 1170 wide can somehow make wider middle of div? <div class="main-container container"> <div>normal 1170 wide content</div> <div> full browser width content</div> </div> so container class make whole div 1170 wide. can somehow make wider middle? bootstrap have class stuff? been trying go through documentation haven't find related case this.

i have group objects consist of other group objects, consist of actor objects. now, when groups , actors rotated, offset , scaled, coordinates in "world", or in relation root node change. how world coordinates of point in actor's local space? to illustrate bit more, here's example of want: group parentgroup; actor childingroup; ... parentgroup.addactor(childingroup); childingroup.setposition(10f, 15f); childingroup.setrotation(45f); // childingroup's position in world float childworldposx = ...; // want know float childworldposy = ...; // ... , this. you can either use actor.localtoparentcoordinates() if want go 1 step higher in hierarchy of groups , actors , or directly use actor.localtostagecoordinates() "stage-global" coordinates directly. in case, libgdx recursively apply localtoparentcoordinates until hits root element of stage.

i manual tester , don't of tool need know how can check memory leaks in mobile device itself. or there other method test it? without having knowledge of coding. ios for ios use instruments. see locating memory issues in app . use leaks instrument of instruments analysis tool find objects in app no longer referenced , reachable. android for android use eclipse memory analyzer tool or android debug monitor described in investigating ram usage while using tools described above, should aggressively stress app code , try forcing memory leaks. 1 way provoke memory leaks in app let run while before inspecting heap. leaks trickle top of allocations in heap. however, smaller leak, longer need run app in order see it.

basically, want seperate common functionality existing projects seperate library project, allow project remain cross-platform when include library. i should clarify when "cross-platform" i'm concerned compiling multiple cpu architectures (x86/x86_64/arm). i have few useful functions use across many of software projects. decided bad practice keep copying these source code files between projects, , should create seperate library project them. i decided static library suit needs better shared library. however, occurred me static library plaform dependent, , including projects cause these projects platform dependent. disadvantage on including source code itself. two possible solutions occur me: include static library compiled each platform. continue include source code. i have reservations both of above options. option 1 seems overly complex/wasteful. option 2 seems bad practice, it's possible "library" modified per project , become out-of-syn...

i, many others, looking venture mobile app development. familiar html5, css3, javascript, php, ruby, .net not java or objective-c. honest, i'm unlikely become mobile developer guru , apps develop unlikely push limits of hybrid such extent ought go native anyway. challenge me gain enough knowledge confidentally align myself 1 of mainstream hybrid development platforms - knowing made right decision according requirements. i've been reading similar posts on , researching popular hybrid mobile application development 'solutions' including: xamarin titanium rhomobile phonegap telerik platform i've come conclusion decision on go not simple. in fact, i'm no closer making decision when started. i'm therefore turning community recommend options based on specific criteria (which believe reflects self-employed developers working on small project-by-project basis rather larger corporate development team ability fund licence costs etc.) the apps build need ve...

i've been following several different tutorials official 1 whenever try install postgresql within container following message afterwards psql: not connect server: no such file or directory server running locally , accepting connections on unix domain socket "/var/run/postgresql/.s.pgsql.5432"? i've looked through several questions here on , throughout internet no luck. the problem application/project trying access postgres socket file in host machine (not docker container). to solve 1 either have explicitly ask tcp/ip connection while using -p flag set port postgres container, or share unix socket host maching using -v flag. :note: using -v or --volume= flag means sharing space between host machine , docker container. means if have postgres installed on host machine , running run issues. below demonstrate how run postgres container both accessible tcp/ip , unix socket. naming container postgres . docker run -p 5432:5432 -v /var/run/postgre...

i developing qt application embedded system limited memory. need receive few megabytes of json data , parse fast possible , without using memory. i thinking using streams: json source (http client) ---> zip decompressor ---> yaml parser ----> objects mapped database data arrive network slower can parse it. how memory yaml-cpp need parse 1mb of data? i parsed raw data decompressor , internal memory used data yaml parser released object mapped database created. possible? does yaml-cpp support asynchronous parsing? json object parsed, can store in database without waiting full content http source. since have memory constraints , data in json, should use low-memory json parser instead of yaml parser. try jsoncpp - although i'm not sure support streaming (since json doesn't have concept of documents). yaml-cpp is designed streaming, won't block if there documents parse stream still open; however, there outstanding issue in yaml-cpp reads mo...
