i'm working on libgdx game uses smaller viewport. public static float box_scale = 10; public static final float virtual_width = (int) (320 / box_scale); public static final float virtual_height = (int) (480 / box_scale); float viewportheight = myconstants.screen.virtual_height; float viewportwidth = myconstants.screen.virtual_height * gdx.graphics.getwidth() / gdx.graphics.getheight(); example viewport can have size (32, 48). use scene2d rendering. reason whenever create textbutton text never centered. bitmapfont used button. freetypefontparameter fontparam = new freetypefontparameter(); fontparam.size = 14; freetypefontgenerator generator2 = new freetypefontgenerator(gdx.files.internal("data/font.ttf")); labelfont = generator2.generatefont(fontparam); labelfont.setscale(1f / box_scale); labelfont.setcolor(color.black); if set box_scale value 1 textbutton acts normal need simulating box2d world. guess create separate labels each button , positio

i've written background task in win 8 app i'm working on periodically check new items in feeds. task works , if app runs, fires off it's completion handler. however, cannot progression event handler fire. i'm using helper class register event/re-attach handlers public static async void registerbackgroundtask(string taskname, string entrypoint, uint checktime, backgroundtaskcompletedeventhandler completionmethod, backgroundtaskprogresseventhandler progresshandler = null) { var backgroundaccessstatus = await backgroundexecutionmanager.requestaccessasync(); if (backgroundaccessstatus == backgroundaccessstatus.allowedmayuseactiverealtimeconnectivity || backgroundaccessstatus == backgroundaccessstatus.allowedwithalwaysonrealtimeconnectivity) { foreach (var task in backgroundtaskregistration.alltasks) { if (task.value.name == taskname)

i need develop maven plugin can start apache ftp-server, run daemon (does not halt build process) , stop goal. unfortunately first attempt daemon threads fails: public class ftpserverdaemon { public static void main(final string[] args) throws exception { thread thread = new thread(new runnable() { @override public void run() { org.apache.ftpserver.main.daemon.main(args); } }); thread.setdaemon(true); thread.start(); thread.sleep(10000); } } the bad thing here jvm not terminate after 10 seconds runs indefinitely. if daemon.main black-box code (however source available ), can prevent jvm terminating in daemon thread? agree assylias , chrylis comments. instead of org.apache.ftpserver.main.daemon.main(args); can try other code there? loop lasts more time main thread sleeps should do, printing number every n se

i'm trying install program called mgiza. compiles cmake , requires boost libraries. used commands cmake . make when run 'make' following errors: d4norm.cxx:(.text+0x95b): undefined reference `boost::system::generic_category()' and likes. inserted following line in cmakelists.txt: find_package( boost 1.41 components system) it worked because more files compiled , warning above disappeared, got warnings: main.cpp:(.text+0x7174): undefined reference `boost::thread::hardware_concurrency()' although have find_package( boost 1.41 components thread) in cmakelists. doing wrong? you need search thread component: find_package(boost 1.41 components thread system) in newer versions of boost.thread should link against boost.chrono find_package(boost components thread chrono system) then need link executable against , add includes: # check if worked out if(boost_found) add_executable(main main.cpp) # executable or library or whatever tar
