When ever a user connects to your hub, the OnConnected() is called. You can over ride this function and implement your own logic if you need to keep track of or limit the number of connections public override Task OnConnected() { //you logic here return base.OnConnected()...

Overloading the disconnect function allows you to handle what to do when a user disconnects. public override Task OnDisconnected(bool stopCalled) { //Your disconnect logic here return base.OnDisconnected(stopCalled); }

/// <summary> /// Overrides the onDisconnected function and sets the user object to offline, this can be checked when other players interacts with them... /// </summary> /// <param name="stopCalled"></param> /// <returns></returns&gt...

Here's how to create an Express server and serve index.html by default (empty path /), and page1.html for /page1 path. Folder structure project root | server.js |____views | index.html | page1.html server.js var express = require('express'); var path = require('path')...

Say you have a table named table or you want to create a table with name which is also a keyword, You have to include the name table in pair of double quotes "table" Select * from table; Above query will fail with syntax error, where as below query will run fine. Select * from "tab...

Usually, J and K move up and down file lines. But when you have wrapping on, you may want them to move up and down the displayed lines instead. set wrap " if you haven't already set it nmap j gj nmap k gk

Monkey patching's main issue is that it pollutes the global scope. Your code working is at the mercy of all the modules you use not stepping on each others toes. The Ruby solution to this is refinements, which are basically monkey patches in a limited scope. module Patches refine Fixnum do ...

drop table table01; drop table table02; create table table01 ( code int, name varchar(50), old int ); create table table02 ( code int, name varchar(50), old int ); truncate table table01; insert into table01 values (1, 'A', 10); insert in...

The simplest approach to parallel reduction in CUDA is to assign a single block to perform the task: static const int arraySize = 10000; static const int blockSize = 1024; __global__ void sumCommSingleBlock(const int *a, int *out) { int idx = threadIdx.x; int sum = 0; for (int i ...

Doing parallel reduction for a non-commutative operator is a bit more involved, compared to commutative version. In the example we still use a addition over integers for the simplicity sake. It could be replaced, for example, with matrix multiplication which really is non-commutative. Note, when ...

Multi-block approach to parallel reduction in CUDA poses an additional challenge, compared to single-block approach, because blocks are limited in communication. The idea is to let each block compute a part of the input array, and then have one final block to merge all the partial results. To do t...

Multi-block approach to parallel reduction is very similar to the single-block approach. The global input array must be split into sections, each reduced by a single block. When a partial result from each block is obtained, one final block reduces these to obtain the final result. sumNoncommSin...

Sometimes the reduction has to be performed on a very small scale, as a part of a bigger CUDA kernel. Suppose for example, that the input data has exactly 32 elements - the number of threads in a warp. In such scenario a single warp can be assigned to perform the reduction. Given that warp execut...

Typically, reduction is performed on global or shared array. However, when the reduction is performed on a very small scale, as a part of a bigger CUDA kernel, it can be performed with a single warp. When that happens, on Keppler or higher architectures (CC>=3.0), it is possible to use warp-shu...

ASP.NET Core provides the status code pages middleware, that supports several different extension methods, but we are interesting in UseStatusCodePages and UseStatusCodePagesWithRedirects: UseStatusCodePages adds a StatusCodePages middleware with the given options that checks for responses with...
