for example, need query last 6 months earliest instance each day (and last day earliest instances in each hours, , last day minutes). thinking of using mongodb , having nested structure like year:{ month:{ day: { hour: { minute: [array of seconds] but first instance have sort array costly. there easier way? would better have date field. and query like: find(date: {$gt : 'starting_date', $lt : 'ending_date'})

in robot framework user guide there section describes how pass variable files , possible variables if needed. example: pybot --variablefile taking_arguments.py:arg1:arg2 my question can use these possible variables arg1 , arg2 in taking_arguments.py file afterwards , if can how? right have this: pybot --variablefile taking_arguments.py:arg1:arg2 taking_arguments.py contents: ip_prefix = arg1 but results in nameerror: name 'arg1' not defined the way use variables in argument file using --variablefile filename.py:arg1:arg2 syntax have variable file implement function get_variables . function passed arguments specify on command line, , must return dictionary of variable names , values. for example, consider following variable file, named "variables.py": def get_variables(arg1, arg2): variables = {"argument 1": arg1, "argument 2": arg2, } return variables this file creates 2 r

i curious if following code thread-safe: public static void methoda () { // given mutableobject not thread-safe (no lock/synchronization used) mutableobject mo = new mutableobject(); mo.setsomevalue(100); // set int value // mutablelist variable must final in order pass thread block final list<mutableobject> mutablelist = new arraylist<mutableobject>(); mutablelist.add(mo); thread t = new thread() { @override public void run() { (mutableobject e : mutablelist) { e.printintvalue(); // print 100 or 0? } } } t.start(); } so, here question. not sure whether contents reachable* "mutablelist" reference visible new thread though there no explicit synchronization/locking used. (visibility issue) in other words, new thread print 0 or 100? print 0 if not see value 100

i doing math game, , have 25 question user answer. so, want mesaure how time user needed solving that? so need timer, stopwatch ability pause time when user click on button. i saw few implementations chronometer, task? if looking figure out how long user took don't need use special object honestly. just make long variable , store starttime system.getcurrenttimeinmillis(); long starttime = system.currenttimemillis(); //do problems here long endtime = system.currenttimemillis(); long totaltime = endtime - starttime; log.i("tag", "it took "+ totaltime / 1000 + " seconds complete problems"); to pausing you'll need long tracks how long paused , subtract totaltime.

is bug or not possible release, stop or kill mediaplayer while it's preparing? i have instance of mediaplayer running in service , stops fine if stop, release, set null, while mediaplayer in prepared state . doesn't if stop, release, set null if it's in preparing state . onprepared() called after stop, release, setting null. workaround this? i think it's common use case when user wants stop mediaplayer before has finished preparing. by looking @ mediaplayer documentation , you're not allowed call stop() on uninitialized object; makes sense because can't stop not running/ready yet. on other hand, release() seems trick after looking @ the source code of mediaplayer . but doesn't harm add boolean flag indicate there no need mediaplayer object anymore , use flag release object if onprepared() gets called. a pseudocode this: public void cancel(){ mcancel = true; } public void onprepared(mediaplayer player){ if(mcancel){

i don't understand going wrong here, hope may spot missed. i'm writing user daemon accepting client develop in java. client connects , sends username password. developed code under cygwin , there works. daemon sends introduction, client sends username , password , daemon responds either disconnecting client or sending ok (not yet done). when test using cygwin works on localhost. ported code hpux , client can connect , receives introduction daemon. when client sends it's username , password doesn't work anymore. daemon receives 1 byte , when tries read again -1 result eagain , nothing else. client doesn't show error , on daemon side there none. when step through code gdb messages revceived completely. :( the code use this, if more info needed can add it: int tcpsocket::receive(socketmessage &omessage, int nbytes) { int max = getsendbuffersize(); if(nbytes != -1 && nbytes < max) max = nbytes; socketmessage sb(max);

i have .net winforms app wherein laptop connected both scale , gps antenna via usb. crazy think have instead web app , on tablet? we're looking make things thinner , smaller (this goes in truck.. driver doesn't need bulk of keyboard either). obviously tablet have have usb port (some do, don't). "stickiness" usb devices, i'd have have, what, silverlight control on asp.net page? more trouble worth? thanks thoughts/advice. you write activex control or browser plugin use usb port (silverlight might not able need). unfortunately these controls have installed on machine manually (unless want lower security settings browser). might better off using clickonce winforms application simplify deployment of new versions , keep using existing codebase. if need read gps data, should use html5 geolocation api: demo , specification

let me describe problem - have struct wraps unmanaged handle (let's call mem). need handle call particular method (say "retain" or alternatively, maintain reference count) whenever copied. in other words, need struct maintains reference count internally (i have mechanism externally well, need way invoke mechanism). unfortunately, c# doesn't let me in way. i cannot make mem class because pass array of these structs unmanaged code , not want convert them 1 one before passing them in (just pin , pass). does know of workaround (il weaving, etc) can applied add behavior in? believe il doesn't prevent me doing this, c#, correct? i happy answer questions framework , restrictions have, not looking - "please change design" or "don't use c# this" answers, much. edit: hosted work answer on github: nopencl library . based on comment, determined following appropriate long-term course of action problems being discussed here. ap
