i've standalone raspberry pi shows webpage server. it reloads after 30 minutes via javascript on webpage. in cases, server isn't reachable short time , chromium shows usual this webpage not available message, , stops reloading (because no javascript page triggers reload). in case, how can still reload webpage after few seconds? now had idea fetch website results via ajax , replace in current page if available. rather refreshing webpage every few minutes, can ping server using javascript ( pingjs nice library can that) now, if ping successful, reload page. if not successful, wait 30 more seconds , ping again. doing continuously, make wait until server open again (i.e. can ping it) i think simpler method compared making own java browser , making browser plugin. extra info : should use exponential function or timeout checking avoid unnecessary processing overhead. i.e. first time out find ping fails, wait 30 seconds, second time wait 30*(2^1) sec, 3...

we building app receives push notifications google play services (transferred gcm few days ago). our problem on devices, after sleeping more 15 min push not arriving, if wifi , 3g on. no matter - flags on server(time_to_live, delay on idle etc.), transferring gcm play services, checking right permissions in app manifest. nothing helps. when device not in sleep mode notifications comes fine. this issue disturbs much. will glad or suggestions. thanks, noam since needs rather sporadic, holding wake lock, partial one, bad choice in terms of battery usage. better approach set alarm periodically wake , run small service check messages. suspect if waited long enough, else wake device , you'd message. edit 1: that said, still might need android.permission.wake_lock permission keep device awake long enough process message before going sleep. @ least apparently did gcm. edit 2: might experiencing results of apparent bug heartbeat interval affects users carr...

i have piece of code runs 1 method , runs same method again different parameters. method takes 45 seconds complete minute , half in total. looks like: //start dbinfopackage migrateddata = runfirstqueries(connectsqlserver, log); dbinfopackage nonmigrateddata = runfirstqueries(connectoracle, log); //end is possible run methods @ same time using threading? just since people giving lower-level answers, using system.threading.thread , whatnot, i'd do: task<dbinfopackage> migrateddatatask = task.run<dbinfopackage>(() => runfirstqueries(connectsqlserver, log)); task<dbinfopackage> nonmigrateddatatask = task.run<dbinfopackage>(() => runfirstqueries(connectoracle, log)); task.waitall(migrateddatatask, nonmigrateddatatask); var migrateddata = migrateddatatask.result; var nonmigrateddata = nonmigrateddatatask.result; that'll run them in 2 concurrent tasks, wait them both finish, , grab results. you'll want add in error handling, th...

i need modify gwt code of vaadin table widget. how begin ?. can find gwt code of table widget? thanks vaadin widgetset sources included in .jar file since gwt compiler needs java source code generate javascript. hence can access sources in ide, instance in eclipse pushing f3 on method o class name in code. in vaadin, server components bundled in vaadin-server.jar, , client widget implementations in vaadin-client.jar. have original code available @ https://github.com/vaadin/vaadin/ normally easier option modifying vaadin widget copying code of classes want modify in project, using same namespace, compiler use them because of classpath preference. remember have compile widgetset each time make modifications in client code. but recommended option extends classes involved in widget (server component, client classes) , use own widgetset implementation. have more info in book of vaadin: https://vaadin.com/book/vaadin7/-/page/clientside.widget.html
