i have powershell code invoking .net method expects class passed parameter. the method accepts null value parameter, , in c# you'd call follows: var t = new foo(null) if translating powershell, 1 try: $t = new-object foo($null) but returns following error new-object : constructor not found. cannot find appropriate constructor type foo funilly enough, exact same error returned if call as: $t = new-object foo so first question why? .net see $null absence of something, oppose type null .net? why 2 instructions above return same error? now, found way around problem follows: $t = new-object foo(@($null)) this works fine, but... why? (@($null)).gettype() returns object[] (@()).gettype() return object[] , if run: $t = new-object foo(@()) i still get: new-object : constructor not found. cannot find appropriate constructor type foo so, second question: difference between @(), @($null) , $null? also, , last question, else don't understand. ...

i created class can use random number generator works better standard rand(). below i've included .cpp file class contains class variables std::mt19937 gen , std::uniform_real_distribution distr. my question whether it's necessary create multiple instances of number generator. instance if have classes , b , each class needs sample random numbers both within range [0,1] better if , b each had own instance of uniformnumbergenerator or should take singleton approach , use 1 instance both classes? uniformnumbergenerator::uniformnumbergenerator(double min, double max) { gen = creategenerator(); distr = std::uniform_real_distribution<double>(min, max); } std::mt19937 uniformnumbergenerator::creategenerator() { std::random_device rd; std::mt19937 result(rd()); return result; } //take sample double uniformnumbergenerator::operator()() { return distr(gen); } one legitimate reason have multiple instances of pseudo-random number generator (...

i using model.create(array) in mongoose. want provide user feedback how many documents have been created , how many of them haven't (i.e. didn't validate). created callback user.create(userstoimport, function(err, docs) { console.log(err); console.log(docs); } the problem if document not validate, receive validation error on single non-valid document, while cannot retrieve information inserted documents. there way information? i think, need .settle() method when.js module . here example of doing using when.js mongoose 3.8.x : when = require('when'); promises = userstoimport.map(function(user) { return user.create(user); // returns promise }); when.settle(promises).then(function(results) { // results array, containing following elements: // { state: 'fulfilled', value: <document> } // { state: 'rejected', value: <error> } }); it's possible without promises (e.g. using async module ), c...

i'm starting multiple threads different things. threads have "endme" boolean variable. when try end threads setting variable , end debugger screams not end processes. after debugging bit found out processes go "ending" part of code when "end me" variable set accordingly. exception happens , thrown. now question is: can exception causes thread not able ended longer? promoting comment answer since correct , might relevant. in absence of code reproduce problem, note if communicating between threads setting boolean variable "endme", need use volatile reads , writes access variable, instance (in .net 4.5): public class threadedworker { bool endme = false; public bool endsignalled { { return volatile.read(ref endme); } } public void signalend() { volatile.write(ref isended, true); } } or in c# versions can use volatile keyword public class threadedworker { volatile bool endme = false; ...
