问题 Im using <PackageReference Include="Microsoft.AspNetCore.SignalR.Core" Version="1.1.0" /> in an asp.net core web api. I can see by default that if I want to send a specific user a message I can call a method such as _hub.Clients.User("c5MOTEmXsEZjoVf-y_sVQD_g-yBis9fvLMbyNJX3M31").SendAsync("MessageUpdated", "ee"); However, I would like to know, is there any way to change this such that I can instead pass in a different value for the userId? For example, users email address instead? Is this

The issue is discussed in

I tried to use margin but it didnt worked. This is my code for card-deck <div class="card-deck"> @foreach ($animes as $anime) <div class="col-sm

问题 I’ve been having some fun setting up GitLab and after spending quite a while hacking away at it, I’ve become relatively used to setting it up, now having done that on two machines, the second time around with much more ease than originally… However, I am faced with a rather large problem, on both machines: My CI pipeline is broken. Somehow, somewhere, my setup is providing a 403 to artifacts once builds are completed, meaning that each and every job that ever technically succeeds will only be
