I am trying to use the ASP.NET signal for the first time - here's what I did: created a new web Has been added to the project and the following signal R packages: I have created the following category: [Hub-name ("chat")] Public class ChatHub: Hub {Public Zero Halo () {Clients.All.hello ( ); }} and the following startup configuration: public partial class startup {public zero configuration (IAppBuilder app) {configure (app); App.MapSignalR (); }} However, whenever I navigate localhost: (port) / api / signalr / chat I get the following error: Protocol error: Unknown transport.

Camel ProducerTemplate possible memory leak -

-
To some degree, this is a bit of a shot in the dark, but we have a process that is dramatically slow One day's course we have found that all the things running on the fuses begin to draw, but when we are running a specific process, JPPropellers are going on, I have found that the increase in magnetic usage increases over time. . Org.apache.camel.ProductTemplate.Send So my main question is, is the way in which the manufacturer product is being used here which is wrong / can this be a problem? exchange foo = new DefaultExchange (getCamelContext (), ExchangePattern.InOnly); Foo.getIn () setBody (obj). Root R = Exchange .getContext (). GetRoute ("do_something_fun"); Creator Template Template = exchange.getContext () CreateProducerTemplate (); Template.send (r.getEndpoint (), foo); Generally, you should not create a productive template on each request as described here: / P> However, because I do not have a complete picture of your application, so you can cr...

javascript - Adhering to a max length setting with jshint -

-
I get several recommendations to compile a maximum of 80 characters when writing javascript, e.g. Google, NPM, Node. JS, Crockford In some cases, though, I do not think how best to do this. MongoClient.connect ('mongodb: // localhost: 27017 / sampleDatabase', function (mistake, database) {if (err)} {throw error;} db = database;}); This will throw a jshint warning because it exceeds 80 characters. Now, do you choose to ignore the warning in this example, or instead choose an option for a solution like MongoClient.connect ('mongodb: // localhost: 27017 / sampleDatabase' , Function (err, database) {if (err) {throw error;} db = database;}); If you can reuse the url variable So, great option if this is a shot, as is often such a call, I would probably do something like this ... / * jslint sloppy: true, white: true, browser: True, maxlen: 80 * / / * global mongo client * / var dbarhh, db; DbErrHand = function (mistake, database) {if (err) {throw error; } ...
