i'm unclear "shared" in openmp. see spec states shared "declares 1 or more list items shared tasks..." seems unclear me. for example, if have following code: #pragma omp parallel shared(num1) for(i=0; i<m; i++) { for(j=0; j < n; j++) { if(myfunc(i,j) < 0) { num1 += 256*u(i,j); } } } will stop race conditions num1 , give accurate result @ end of loop? if not, do? will stop race conditions? no, won't : it programmer's responsibility ensure multiple threads access shared variables (such via critical sections) shared section make same variable visible multiple threads. you can use critical sections or atomic access syncronization, in this case you'd better use reduction clause: #pragma omp parallel reduction(+:num1)

i'm trying make filter on screen, hiding doesn't meet requirements. this i've come far. im not sure doing wrong jquery : jquery('#searchbox').on('keyup change', function() { var search = $('#searchbox').val(); //for each h4 $('h4').each(function(){ var h4id = $(this).attr('id'); if ($(h4id).contains(search)) $(this).show(); else $(this).hide }); html : <input type="search" name="search" id="searchbox"/> <h4 id="adminstrator">administrator</h4> <h4 id="john,smith">john smith</h4> <h4 id="jane,smith">jane smith</h4> (i'm using jquery 1.9.1) (so, if start typing smith, "administrator" h4 should disappear. .contains not give text content of selector. search elements inside selector. try approach .. can lot more optimized

i've noticed small inconsistency i'm hoping verify either quirk of html5, or specific video.js . it seems if call video.js' currenttime() function whilst providing new time, further calls currenttime() (to current time) not return correct time (it return previous time), until timeupdate event fires. after timeupdate event, currenttime() return correct time. for example, assuming video hasn't started playing yet, video.js has loaded, along video meta etc: videoplayer.addevent('timeupdate', function() { console.log('event callback: ' + player.currenttime); }); console.log('original time: ' + player.currenttime); player.currenttime(100); console.log('new time: ' + player.currenttime); the output expecting like: original time: 0 new time: 100 event callback: 100 however i've receiving is: original time: 0 new time: 0 event callback: 100 any insight fantastic! edit: can reproduce in chrome , s

assuming have following array of file names wish zip my @files = ("c:\windows\perl\test1.txt", "c:\windows\perl\test2.txt", "c:\windows\perl\test3.txt"); if $obj = archive::zip->new(); foreach (@files) { $obj->addfile($_); } $obj->writetofilenamed("zippedfolders.zip"); when open zippedfolders.zip see contains subfolders, namely windows , perl , latter contains test1 , test2 , , test3 . reason, folders getting zipped up. how can make files zipped , not have click windows perl folders access zipped files? as have see, if use addfile add disk file archive, archive::zip adds archive member same path file had originally. if want stored different can pass second parameter used name , path of archive member created. for purposes suggest use core file::basename module remove path filename , pass basename second parameter. the code below demonstrates. something else need aware of can't use single ba

i have main report runs multiple sub-reports. 1 of sub reports runs fine in preview, when deploy report , run browser, get: error: subreport not shown. i've done research , still not sure issue is. i've tried in different browsers, data sources both main report , sub report use same shared data sources. , main report , parameters seem pass fine (since works in preview, assuming). the error doesn't tell me - has else had issue? or ideas how debug? many thanks! issue resolved. needed deploy subreport well, not build.

our application has several dependencies not available pcl libraries (e.g. restsharp, websocket4net, reactive extensions), available each platform plan target. what's best approach handling scenario in mvvmcross? simplest? there various ways approach this. if problem large, can abandon pcl approach, , use multiple platforms specific class libraries. these libraries can reference mvvmcross pcls , platform specific versions of restsharp, etc. discussions on pro's , con's of see - what advantage of using portable class libraries instead of using "add link"? in general, take file-linking approach if i've got include large legacy library (e.g. 1 customer had large business logic library talked 3 separate wcf services...) some of libraries mention may have pcl ports and/or alternatives - e.g. reactive extensions has official pcl port - see http://blogs.msdn.com/b/rxteam/archive/2013/02/06/rx-2-1-is-here.aspx for simple rest calls, we've
