when click button, cycle starts read database , send each row of query server. when response - cycle continues. code implemented follows private manualresetevent _mre = new manualresetevent(true); and thread startupload = new thread(() => { //read database foreach (datarow dr in dt.rows) { //send request _mre.waitone(); } }); startupload.start(); the problem when requests sent may not answer. in case normal. if not, answer comes, cycle stops. need inside loop timer, in case of stopping cycle due lack of response continue cycle in 30 seconds. the timer have do _mre.set(); important: you're setting manualresetevent initial state true , set false if you're willing stop current process , wait signal. edit: example private manualresetevent _mre = new manualresetevent(false); private void readthedatabase() { thread startupload = new thread(() => { // read data foreach (datarow

what should best of generating nodes csv file in nightly cron job? there module doing or better programatically create content using node_save in hook_cron() function? you can use drupal feeds module achieve this. feeds can periodically import entities data source (eg. csv or rss feed). if node-processor of feeds module not fit requirements, should try create custom module suggested.

my requirement remove arraylist this: arraylist<user> user = new arraylist<user>(); listiterator<user> outeriterator = null; listiterator<user> inneriterator = null; user outer = null; user inner = null; for(outeriterator = user.listiterator(); outeriterator.hasnext();) { outer = outeriterator.next(); for(inneriterator = user.listiterator(); inneriterator.hasnext();) { inner = inneriterator.next(); if(someoperationon(outer,inner)) { inneriterator.remove(); } } } above code giving exception exception in thread "main" java.util.concurrentmodificationexception as expected, because trying remove inneriterator while outeriterator iterator on same object(user). is there way remove element arraylist using listiterator in loop inside loop? in isolation, calling remove() on iterator proper way avoid concurrentmodificationexception when removing item collection you're iterating. ho

i have large xml document iterating through. xml's use attributes rather node values. may need find numerous nodes in file piece 1 grouping of information. tied via different ref tag values. each time need locate 1 of nodes extract data looping through entire xml , doing match on attribute find correct node. there more efficient way select node of given attribute value instead of looping , compare? current code slow useless. currently doing numerous times in same file numerous different nodes , attribute combinations. my $searchid = "1234"; foreach $nodes ($xc->findnodes('/plm:plmxml/plm:externalfile')) { $id = $nodes->findvalue('@id'); $file = $nodes->findvalue('@locationref'); if ( $searchid eq $id ) { print "the file name = $file\n"; } } in above example looping , using "if" compare id match. hoping below match node attribute instead... , more efficient looping? my

rather doing (which dozens of times across site): $posts = post::with('user') ->with('image') ->get(); is possible automatically call with('image') whenever with('user') called? in end, just: $posts = post::with('user') ->get(); and still eager load image ? add following in model: protected $with = array('image'); and should trick. the $ with attribute lists relations should eagerly loaded every query.

what simplest way delete object list based on value of property? i'm looking equivalent of $pull in mongodb. my list looks simple this: [{a: '1' , b: '1'},{a: '2' , b: '2'}] and i'd remove array object property a set '1'. in mongodb, i'd this: model.update({_id: getcorrectparentobj},{ $pull: {listideletefrom: { a: '1' } } },(err, result)=>{}); how can same result immutablejs? you filter immutable list: var test = immutable.list.of(immutable.map({a: '1'}), immutable.map({a: '2'})); test = test.filter(function(item) { return item.get('a') !== '1' }); however, filter on non-empty list result different immutable list, may want check occurrence of {a: 1} first: if (test.some(function(item) { return item.get('a') === '1'; })) { test = test.filter(function(item) { return item.get('a') !== '1' }); }

i'm writing idisposable class, intended used in multi-threaded environment. want make sure dispose() called once. far came with: int _isdisposingasint = 0; public void dispose() { if (interlocked.exchange(ref _isdisposingasint , 1) == 0) return; // dispose code .... } is there more elegant way of achieving this? edit important addition - not intend call dispose() multiple threads. intend use _isdisposingasint signal background thread, listens serial port, , may terminate ungracefully, should not re-throw exception. firstly, declare _isdisposingasint volatile because want updated in threads. secondly, need declare object , lock it/exchange it's value in order know have been @ dispose. did in 1 line, there no shorter that. can in efficient way: if(interlocked.compareexchange(ref _isdisposingasint , 1 , 0) == 0) this way check before exchange if value 0, , u save bus , blocking threads.

in scala can use global executioncontext if don't need define own importing scala.concurrent.executioncontext.implicits.global . my question why forkjoinpool chosen executor instead of threadpoolexecutor . my understanding fork-join framework excellent @ recursively decomposing problems. you're supposed write code breaks task halves, half can executed in-thread , other half can executed thread. seems particular programming model , not 1 applicable handling execution of general asynchronous tasks across wide range of possible applications. so why forkjoinpool chosen default execution context people use? work-stealing design result in improved performance if don't use full fork-join paradigm? i can't speak scala designers, idiomatic use of scala future s involves creation of lot of small, short-lived tasks (e.g. every map call creates new task) , work-stealing design appropriate. if care these kind of precise details might prefer use scalaz-concur

the naive way linearly iterate range , multiply each number in range. example: array: {1,2,3,4,5,6,7,8,9,10}; multiply index 3 index 8 2. assuming 1 based index. result array should : {1,2,6,8,10,12,14,16,9,10}; i know binary indexed tree can used 'sum' part. how can efficiently multiply given range number? if want modify array, can't better naive linear algorithm: have iterate entire range , modify each index accordingly. if mean like, have update operations described , query operation find sum in range x y , segment tree can so. for each update operation left, right, value , each node associated range included in [left, right] , sum gets multiplied value , update accordingly , stop proceeding recursion. apply intervals not recurse on, instead of updating sum, store in each node how associated interval multiplied by. when returning recursion, can recompute actual sums according info. pseudocode : update(node, left, right, value): if [left, ri
