i have impression question asked hundred times, never answered. i working on smallish project, @ point should released big 3 pc platforms (windows, mac & gnu/linux), locking technology bad idea. luckily unfortunately, now, during development, target 32-bit windows. on code level, cross platform development relatively easy, if pick right libraries. building software on multiple platforms relatively straight forward, looking using either gyp or cmake. the problem dependencies. build project need: sdl, sdl_image, sdl_ttf, iconv, libxml2, libxmlmm, sigc++, wxwidgets, glew, bullet, openalsoft , maybe more added later. so far have found 3 options: check in sources , build them part of project check in binaries manage dependencies outside of source tree the first seems overkill, since need maintain fork of library , custom build system. the second option sounds thing when target 1 or maybe 2 platforms. if count different targets, including 32/64 bit variants, starts

i not want have $http mocked. main reason writing integration tests want have ajax requests executed. in tests none gets triggered. suggestion more welcomed. the angular mocks provide mocked $httpbackend when using jasmine tests, actual $httpbackend still exists. need tell provider use original when inject service. in test: var original_http_backend = null; angular.module('ng').config(['$httpbackendprovider', function($httpbackendprovider) { original_http_backend = $httpbackendprovider; }]); beforeeach(module(function($provide) { $provide.provider('$httpbackend', original_http_backend) })); it's worth pointing out approach, in general, bad way test front end code. because adds backend dependency, cannot isolate front end behavior. preferred mock out response , test that. i did end using feature though, since our mock responses developed on end testing there, , didn't want repeat objects. method allowed me use them.

assume have read/write monitor implementation in java. several readers or 1 writer can access database @ 1 time (not both) class rwmonitor{ private int readers = 0; private boolean writing = false; public synchronized void startread(){ ..} public synchronized void endread(){ notifyall(); readers--; } public synchronized void startwrite(){ ..} public synchronized void endwrite(){ notifyall(); writing = false; } } now, matter if notifyall() not last statement in synchronized method? assume: 1) endread() executes 2) notifyall() notifies waiting threads 3) reduces reader count. when executes notifyall() , more costly since woken threads waiting lock on rwmonitor released? (assuming thread has lock on rwmonitor still @ readers--; ) it not matter if last statement. to quote javadoc notifyall() : the awakened threads not able proceed until current thread relinquishes lock on object.

hello have query returns computer names corresponding ip adress follows: select distinct top (100) percent dbo.inv_aex_ac_tcpip.[ip address], dbo.inv_aex_ac_tcpip.[host name] dbo.inv_aex_ac_identification inner join dbo.inv_aex_ac_tcpip on dbo.inv_aex_ac_identification._resourceguid = dbo.inv_aex_ac_tcpip._resourceguid this returning results such as: computer: ip: frank's computer 10.0.0.1 frank's computer 10.0.0.3 nick's computer 10.0.1.0 is possible return first "frank's computer" row, , exclude other one? thanks! yes, possible, how depends on dbms of choice. functionality looking group by , puts similar results in same column, need know non-aggregated values, putting them in aggregate function max , min or avg . your results fine this: select min(dbo.inv_aex_ac_tcpip.[ip address]) ip, dbo.inv_aex_ac_tcpip.[host name] name dbo.inv_aex_ac_identification inn

i trying figure out how use extendedlog4netlogger.cs change log file path dynamically @ runtime or using loggingfacility? this should similar using log4net directly this: log4net.globalcontext.properties["logname"] = logname; how access extendedlogger if register log4net integration this: container.addfacility<loggingfacility>(f => f.uselog4net()); update: use following code register extended logger container.addfacility<loggingfacility>(loggerimplementation.extendedlog4net).withconfig(configfile).tolog(lo‌gger)); i no runtime exceptions , logger not null instance don't see log file created @ using global properties, set config value appender: <file type="log4net.util.patternstring" value="%property{logname}" /> if set file property in config file full path work. wondering if not working because configuration done before setting global variable. extendedlogger.globalproperties["logname"] =

i have made simple listview demo in android. want when item list selected should displayed on next activity,i have tried following code: act1.java package com.example.listview; import java.util.arraylist; import android.os.bundle; import android.app.activity; import android.content.intent; import android.view.menu; import android.view.view; import android.widget.adapterview; import android.widget.adapterview.onitemclicklistener; import android.widget.arrayadapter; import android.widget.listview; import android.widget.simpleadapter; public class mainactivity extends activity { listview ls; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); ls=(listview)findviewbyid(r.id.lv); string[] s = {"ahmedabad","baroda","chndigarh","delhi","jharkhand","hariyana","ilahabad","jammu",&

how query collection matches exact fields of objects in array? since test case more explicit, here test pass. a = invitation.create(guests: [ guest.new(player: 'bbb'), guest.new(player: 'ccc') ]) b = invitation.create(guests: [ guest.new(player: 'ccc'), guest.new(player: 'bbb') ]) c = invitation.create(guests: [ guest.new(player: 'bbb'), guest.new(player: 'ccc'), guest.new(player: 'ddd') ]) # request find invitation bbb , ccc player_id of guests, regardless order. result = invitation.collection.find(...) assert_equal result, [ a, b ] my use case invitation system same combination of guests can't exist, when new invitation sent, need check if 1 exact same guests (regardless order). note: use array of guest objects since carry additional data. here example data set ( https://gist.github.com/anonymous/5507735 ). based on answer nyde1319; feels hackish, since there's no other answers yet here goes: db.i

i have function fills pointer struct. fill gtk callback, use global pointer current "nivel" i'm using accesible other functions. i'm afraid may have memory problems. the point is, believe memory being "filled" alright. but, program gets out of function calls function make struct, 1 of several outcomes: 1 - error: glibc detected corrupted double linked list 2 - error: glibc detected 3 - segmentation fault. 4 - no error @ all. the error changes execution execution, tells me it's gotta memory, perhaps i'm not handling scope of struct correctly, can't find solution it. i'm pretty sure struct being made correctly, though. appreciated. code bellow, has parts ins spanish i've commented important bits. help! //struct, consists of 2d array , size info. struct nivel { size_t filas; size_t columnas; int **mapa; }; //global current level pointer, fill call function within function. struct nivel *nivel_actual; //fun

i have vb.net application run in debug mode. have 3 lines dim svalue$ svalue = "test" debug.print svalue when not running, set breakpoint on lines svalue = "test", , on line debug.print svalue. now when start debugging, breakpoint on line debug.print svalue disappears, , debug.print not performed. however, breakpoint on line svalue = "test" stays there. does know might go wrong here? switching x86 anycpu helped. strange.

i trying build , run complicated code written else, don't know , can't ask them help. code reads bpf (brain potential file) , converts readable ascii format. has 3 c files, , 2 corresponding header files. got build minor changes, crashes segmentation fault. i narrowed problem down findsectionend() (in readbpfheader.c) , find error occurs when sscanfline() (in file sscanfline.c) called (code both below). ui1 defined unsigned char. si1 defined char. just before returning sscanfline(), address pointed dp 0x7e5191, or similar ending 191. however, on returning findsectionend(), dp points 0x20303035 , says 'address 0x20303035 out of bounds', causes fault @ strstr(). loop in findsectionend() runs without problem 14 iterations before fault occurs. have no idea going wrong. hope information have given here adequate. ui1 *findsectionend(ui1 *dp) { si1 line[256], string[256]; int cnt=0; while (sscanfline(dp, line) != eof){ dp = (ui1 *)strstr(dp,

if run gcc -o0 , , hand-optimize code using techniques such ones mentioned here , case optimized code run faster unoptimized code when run gcc -o3 ? that is, if hand-optimize code under particular compiler optimization level, true these optimizations still productive (rather counterproductive) under different (higher or lower) compiler optimization level? it might not same in different compiler. compiler can away hand optimization, mean ignore them. heavily depends implementation , behavior of compiler itself. of optimizations request compiler, can dropped @ time, (mostly without notification)

on www.onsitebac.com/viewmyblows google site i've inserted apps script gadget (by pasting url of apps script published service). apps script gadget allows user enter value (their 'blow number') , view corresponding data (based on api calls google fusion tables). the problem apps script gadget not load expected. not load @ in ie8 , loads 'this application created user, not google' message in chrome , firefox. want application load part of web page (with no messages or errors). please advise...thanks! the google message appear no matter, long user hasn't disabled message in past. not see either, it's policy. as not displaying in ie8. couple things, google doesn't ie, , not older versions. google fond of saying "gas works in modern browser." and, don't count ie 1 of those. but haven't provided code... i'm going take guess due styling. i'd used answer offered in applying dry principle in google apps scr

in c++ programming, when need worry precision issue? take small example (it might not perfect 1 though), std::vector<double> first (50000, 0.0); std::vector<double> second (first); could possible second[619] = 0.00000000000000000000000000001234 (i mean small value). or sum = second[0]+second[1]+...+second[49999] => 1e-31 ? or sum = second[0]-second[1]-...-second[49999] => -7.987654321e-12 ? my questions: could small disturbances in working double type numbers? what may cause these kind of small disturbances? i.e. rounding errors become large? please list them? how take precautions? if there small disturbance in operations, mean after these operations, using if (sum == 0) dangerous ? 1 should use if (sum < small) instead, small defined small value, such 1e-30 ? lastly, small disturbances result negative value? because if possible, should better use if (abs(sum) < small) instead. any experiences? this reference document floating p

i storing datetime fields utc time. when user requests web page, take preferred local timezone (and not local timezone of server machine) , automatically display datetime fields in web forms local dates. of course, apply conversion on every datetime.tostring() call in every form or implement helper utility time consuming task, , there 3rd party components tricky configure custom datetime display templates. essentially, make datetime class behave follows: from moment on web request, whenever code calls datetime.tostring(), convert local time using timezone offset given @ beginning of web request, if possible, please keep .net core library datetime.tostring() calls intact (i don't want mess event logging timestamps etc.) is there way it? btw, using asp.net mvc 4, if matters. you can't directly asked for, suggest alternatives. nicholas pointed out, there nothing in http give time zone directly. option 1 first, decide type of time zon
