this code works fine. question happens within net.connectionstream when use copyto() method? system.net.httpwebrequest request using (filestream filestream = new filestream("c:\\myfile.txt") { using (stream str = request.getrequeststream()) { filestream.copyto(str); } } more specific: happens data? 1. write memory , upload then? (what's big files?) 2. write network directly? (how work?) thanks answers it creates byte[] buffer , calls read on source , write on destination until source doesn't have anymore data. so when doing big files don't need concerned running out of memory because you'll allocate as buffer size, 81920 bytes default. here's actual implementation - public void copyto(stream destination) { // ... bunch of argument validation stuff (omitted) this.internalcopyto(destination, 81920); } private void internalcopyto(stream destination, int buff

besides obvious language architecture differences (respectively ruby vs. nodejs) there differences between rubygem guard , grunt.js ? or wrong comparing two. dissimilar? also, project has larger development community? guard , grunt perform similar functions, differ in ways triggered. guard based on watching files events, while grunt based on running 'tasks' based on if events occur. real differences language, , how run code based on file events , such. as guard/grunt communities, virtually equal utilize different ruby/node.js tools. both great tools. use guard if use ruby/rails, , grunt if use node.

( focus of radio button changes source images change radio button focus highlighted other image). problem: when interact mouse (see source code) source (image) not change more…..no idea… while source changing before mouse interaction. checked in debugger source line never reached after mouse interaction. i guess not right way change source image…please me solve or give me suggestion alternative rectangle { //main container id: rectangle1 x: 0 y: 0 width: 480 height: 620 color: "#ffffff" item { // focus scope container id: focus_object focus : true image { // radio button 1 id: rock x: 5 y: 6 fillmode: image.preserveaspectfit smooth: true focus:true

i writing small bash script find mx records of given domain, print out hostname, ip address, , reverse address ip address. able store each hostname, ip, , reverse address 3 arrays: $mxhosts[@] $mxips[@] $mxrhost[@] each contains same number of values, , depend on how many mx records domain has. want do, print out line data 3 arrays, number of values in arrays. how able either a. create new array condenses 3 arrays 1 data or b. print out data 3 arrays using echo? examples: $mxhosts[0] = aspmx.l.google.com. $mxips[0] = 74.125.129.27 $mxrhost[0] = ia-in-f27.1e100.net. from that, i'd print out this: aspmx.l.google.com. :: 74.125.129.27 :: ia-in-f27.1e100.net. for each mx record, run this: [~/scripts]# ./whomails google.com aspmx.l.google.com. :: 74.125.129.27 :: ia-in-f27.1e100.net. alt1.aspmx.l.google.com. :: 74.125.129.27 :: qe-in-f27.1e100.net. etc.. so far i've tried few different methods, using loops, if domain has multiple mx records print out possib

i have method more or less calls 3 different async methods , returns "result" object containing success message. of 3 async methods may throw sshexception , i've placed 3 within try{}catch{} traps aggregateexception , handles sshexception , , returns failure result object. since i'm on .net 4.0, can't use async/await (which believe solve problem easily), turn method 1 returns task containing 1 of 2 results: "success" if 3 previous tasks completed successfully. "failure" if any of previous tasks faulted. ideally, task execution stop @ first canceled task (e.g. taskcontinuationoptions.notonfaulted 3 work tasks). here's sample code: public uploadresult uploadfiletodir(string dir, string text) { try { sftpclient.cd(dir).wait(); // task var filename = this.getfilename().result; // task sftpclient.writefile(filename, text).result; // last task return uploadresult.success; } catc

i'm trying implement plugin system in angularjs allow users configure "widgets" see on page. each widget defined controller , template(url). possible create directive instantiates controller, invokes template , transcludes resulting content? the goal this: <div class="widget" ng-repeat="widget in widgets"> <widget controller="widget.controller" templateurl="widget.templateurl"></widget> </div> there 2 ways this; 1 uses helper directives available (like nginclude , ngcontroller ) , second manual; manual version might faster, cannot sure. the easy way: the easy method simple create new element ngcontroller , nginclude attributes, append directive's element, , $compile it: var html = '<div ng-controller="'+ctrl+'" ng-include="'+tpl+'"></div>'; element.append(html); $compile( element.contents() )( scope ); the manual wa

i iterating through list of objects of type "prvemployeeincident". the object has following properties: public datetime dateofincident { get; set; } public bool iscountedasapoint; public decimal originalpointvalue; public bool isfirstincollection { get; set; } public bool islastincollection { get; set; } public int positionincollection { get; set; } public int daysuntilnextpoint { get; set; } public datetime datedroppedbysystem { get; set; } public bool isgoodbehaviorobject { get; set; } my list sorted dateofincident property. find next object up list iscounted == true , change iscounted = false. one question: 1) how find object list ? if understand question correctly, can use linq firstordefault : var nextobject = list.firstordefault(x => x.iscountedasapoint); if (nextobject != null) nextobject.iscountedasapoint = false;

i trying compare various classifiers on data, such lda , svm etc, visually investigate separation hyperplane. currently using classificationdiscriminant lda classifier, unlike svm can draw hyperplane on graph, not find way plot hyperplane of lda classifier. the following script how produce sample data , been classified using classificationdiscriminant: %% data & label x = [randn(100,2); randn(150,2) + 1.5]; y = [zeros(100,1); ones(150,1)]; %% plot gscatter(x(:,1),x(:,2),y); %% train lda classifier c = classificationdiscriminant.fit(x,y); can please me plot hyperplane of separation c ? suggestion great help. furthermore, sample above in 2d, however, i'm interested in plotting them in 3d (i.e. sample data x has 3 columns). more great if can help. borrowing example in matlab's classify() documentation: class1 = 1; class2 = 2; k = c.coeffs(class1,class2).const; l = c.coeffs(class1,class2).linear; f = @(x,y) k + [x y]*l; hold on; ezplot(f, [min(x(:,1)

i have been working on new project work , have been running weird issue application takes long time return response both in dev , prod. returns response fast. read few posts on here possible reasons why none of them have solved issues. at first thought because had few sub requests made removed still had same issues. my average request between 20-30mb in dev. trying use profiler me figure out may coming from, every request shows longest part of request different area. example, in 1 request longest section controller, in request same page template listener, on security/firewall listener. for example, fast request on homepage takes 116ms. wait min, refresh , takes 9467ms, or have seen take 30,000+ms. while can live little slowness in dev mode, prod doing same things. fast, slow. apc cache enabled. doctrine queries take 4-20ms complete depending on page. i running php 5.3 decided upgrade 5.4 see if helped, still same issues. using latest stable build of nginx. php in fpm. ser
