Summary:

It had automatic updates in the App Store, the XCode update has been given and it has broken, it stays "Installing" and nothing happens from there. I've tried canceling the update, restarting the MacBook and nothing.

Photos:

They are not from my team and perfectly exemplify the scenario I have.

From here it does not advance, it remained static.

I tried:

1. Canceling the update didn't work.
2. Rebooting the computer didn't work.
3. Uninstalling and reinstalling XCode didn't work either.

Analysis:

1. I opened the Console Application, not the Terminal.
2. In the search bar, I checked for the "App Store".
3. I pressed the Start button.

In the Log lines, it said how the installation process was going, something like: "... Completed: 933 of 1000", After a while, I kept seeing the same "... Completed: 933 to 1000", and from there it didn't go any further. Considering that I left it for about a half hour and nothing.

Any idea how to fix it?

Aloha~ Good afternoon, I have a curious situation, in an Apache I have a system made in ASP.net Core and when I try to use _httpContextAccessor.HttpContext.Connection.RemoteIpAddress.ToString();the IP that returns me it is 127.0.0.1having been published on the server, where, in theory, requests are received with its remote Client IP, any idea what is missing? In theory it should work.

Is there a way to apply the concept of "Hot Reloading" in the development process using Blazor? That is, instead of giving F5 on each change made, can it be done automatically?

A moment ago I saw a very interesting question about how to generate a DataSet based on a generic list that comes from a JSON , since the question was deleted and I managed to copy the JSON structure , here is a collaboration with the community:

[
  {
    "CO_EMPR": "18",
    "TI_REQI": "RAL",
    "NU_REQI": "0001-0000000049",
    "SECUENCIA": "4",
    "CODIGO_ITEM": "600101008",
    "CANTIDAD_SOLICITADA": "5"
  },

I have a mobile app in Xamarin Forms 3.2, which works fine on Android, however when I run the build for iOS, it compiles without errors, loads the iOS emulator, and throws the following exception:

Objective-C exception thrown.  Name: NSInternalInconsistencyException Reason: -[UISearchBar sizeThatFits:] does not support passing non-finite values ({inf, 56})

Within the properties, I have the following:

-[UISearchBar sizeThatFits:] does not support passing non-finite values ​​({inf, 56})

It strikes me that it works well on Android and that it breaks on iOS; Anyway, effects of the learning curve, by the way, this is the XAML that I am using:

<SearchBar Grid.Row="0" Margin="0,20,0,0" Placeholder="Search" SearchCommand="{Binding Path=SearchingCommand}" Text="{Binding Path=SearchQuery}"></SearchBar>

There is a tool called ngrok ( http://ngrok.io ) that basically makes your localhost viewable from anywhere thanks to the magic of the internet. It is one of those tools that will make your life easier as a developer.

Once I downloaded the app and ran it, it gave me the link to view, so far so good, I go to the iPad to try and...

Invalid Host Header 

I tried to open any other page that I have on localhost and they all gave me the same, what do we do? we cry?

I have an interesting case to analyze, the web application I developed works great in mobile browsers: Firefox, Google Chrome, however when viewing the application in Safari on an iPhone, for some reason it takes too long. I have to go into Sherlock Holmes mode, debug and solve the case; I am surprised that Safari does not have the legendary F12. Maybe he's in ninja mode and has it hidden somewhere. Do they know how to display it or if you have to pay for an app from the AppStore to access it?

I have a somewhat strange situation, where the documentation that mentions the error: https://v2.vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties is not being useful to me or I am not understanding it as it is supposes.

With no further details to add at the moment, let's get to the code:

Component:

Vue.component("product-card", {
  props: ["title", "price", "url", "sku", "retina", "image", "cssclass"],
    template: `<a v-bind:class="cssclass" v-bind:href= "url">
            <img
                v-bind:alt = "title"
                v-bind:src = "image"
                v-bind:srcset = "retina"
            />
            <h3 class = "fx-product-carousel-cell__title"> 
            {{title}}
            </h3>
            <div class = "fx-price" > {{price}} </div>
            </a>`
}); 

Component Usage:

 <product-card v-for="product in introductionProducts"
      v-bind:key="product.ProductCode"
      v-bind:title="product.Name"
      v-bind:url="getURL(product.ProductCode)"
      v-bind:image="getSrc(product.ProductCode)"
      v-bind:retina="getRetina(product.ProductCode)"
      v-bind:cssclass="fx-display-board__item"
      v-bind:price="product.Price"
 ></product-card>

And it gives me the error:

Solution attempts:

It occurred to me that maybe the problem comes with the name of the class, yes, because of the hyphens, so I replaced the name of the class with

v-bind:cssclass="fxdisplayboarditem"

No, it didn't work.

If I move the cssclass property statically to the component template, it remains:

<a class="fx-display-board__item" v-bind:href= "url">

Previously being:

<a v-bind:class="cssclass" v-bind:href= "url">

It works, however what is the point of creating a component? Make it reusable... Any ideas?

I have followed the official Microsoft documentation to install Dot Net Core on the server, it says to run the following commands:

wget -qO- https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.asc.gpg
sudo mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/
wget -q https://packages.microsoft.com/config/debian/9/prod.list
sudo mv prod.list /etc/apt/sources.list.d/microsoft-prod.list
sudo chown root:root /etc/apt/trusted.gpg.d/microsoft.asc.gpg
sudo chown root:root /etc/apt/sources.list.d/microsoft-prod.list

So far so good, the problem comes when executing the command:

sudo apt-get update

Resulting in the following error:

Fetched 91.8 kB in 0s (103 kB/s)
Reading package lists... Done
E: The method driver /usr/lib/apt/methods/https could not be found.
N: Is the package apt-transport-https installed?
E: Failed to fetch https://packages.microsoft.com/debian/9/prod/dists/stretch/InRelease
E: Some index files failed to download. They have been ignored, or old ones used instead.

What do we do, cry?

Good morning SOes brothers, I have this situation:

I need a dictionary with data previously defined, this dictionary is supposed to be read-only so the million dollar question is:

How can I define a static dictionary with initialized elements?

This way when you have to work some clave, the valorwill be obtained from the dictionary.

I have AngularJS (1.5.5) and while testing, the arrow functions don't work in Internet Explorer 11, I have the following code:

return availability.price && availability.options.filter(x => x.leadTime >= 0).length > 0;

And also in this other block it generates an error:

.then(result => { console.log(result); })
.finally(() => { $window.location.reload();});

What do I do, start crying?

Good day community, there is a common scenario and I haven't seen any similar questions, so I'll share the solution right away.

Basically, we have a list of items and we want to update a particular property using Linq.

using System;
using System.Linq;
using System.Collections.Generic;                   
public class Program
{
    public static void Main()
    {
        Console.WriteLine("¡Saludos Hermandad de SOes!");

        List<Movil> lista = new List<Movil>(){
        new Movil(){
            Id = 1, Marca = "iPhone", Conexion = "LTE"},
        new Movil(){
            Id = 2, Marca = "Samsung", Conexion = "4G"},
            new Movil(){
            Id = 3, Marca = "Xiaomi", Conexion = "4G"}
        };

        Console.WriteLine("Seleccionar todos los 4G");

        var listaFiltrada = lista.Where(elemento=>elemento.Conexion.Equals("4G", StringComparison.InvariantCultureIgnoreCase));
        foreach(var item in listaFiltrada){
            Console.WriteLine("{0} - {1} - {2}", item.Id, item.Marca, item.Conexion);
        }

        Console.WriteLine("Actualizando de 4G a LTE");
        //Aqui quiero hacer uso de Linq en vez de usar un bucle for, foreach
    }

    public class Movil{
        public int Id {get;set;}
        public string Marca {get;set;}
        public string Conexion {get;set;}
    }
}

In the backend I have a method that returns a PDF file using the GET method, HttpGetto be exact. To access this file I have a function location.href = "Url";where I specify the URL and everything is fine, the file is launched to the user.

The problem is that the user has a nice modal that says to wait and his wait can be longer or shorter, regardless of this the modal is still there. The rendering time varies a lot, it can be 3 seconds or it can be 30.

The following code has a default behavior so that the modal closes in 17500 milliseconds, in other words: 17.5 seconds.

HTML:

<a href="#" onclick="ExportarPDF();" id="PDFdoc">
    <input type="button" id="btnFullPDF" value="Ejecutar Reporte" class="btn btn-info mostrarLoadingModal" />
</a>

JavaScript:

function ExportarPDF(){           
    var url = $("#magicButton").attr("href");
    console.log("url");
    console.log(url);
    location.href= url;
    setTimeout(function(){
        $("#modalLoading").modal('hide');
    },17500);
}

How do I know when that location.hrefhas finished loading successfully? Is there any other way? Knowing this I can close the modal just at the time that the user has the "Save file" window and holy remedy.

I have the following scenario:

/Views/Shared/_Layout;
/Areas/Area1/Views/ControllerName/Index
/Areas/Area2/Views/ControllerName/Index
/Areas/Area3/Views/ControllerName/Index
...
/Areas/AreaN/Views/ControllerName/Index

Is there a way to force all areas to use the general Layout defined in the first line of the sample code above as a base?

I have the following scenario:

1. Receive variables from the server.
2. Select in a dropdown one of the values ​​of a variable from the previous point.
3. This dropdown has an "onchange" event that generates the elements of the next dropdown (cascading data load).
4. The second dropdown must have another value of one of the variables (point 1) selected.
5. Run a submit.

HTML

<select id="SelectID" name="SelectName" onchange="LlamarFuncion()">
  <option value='Los Angeles'>Los Angeles</option>
  <option value='San Bernardino'>San Bernardino</option>  
  <option value='Riverside'>Riverside</option>
  <option value='Orange'>Orange</option>  
</select>
<select id="SelectID2" name="SelectDetail">
</select>

javascript

<script>
function LlamarFuncion(){
   //Esto demora
}
</script>

I tried to make a bind, a trigger and it didn't work. It happens to LlamarFunciontake a while, so putting a setTimeout() would not be a good option either.

It is worth mentioning that the code is in a document readyso it will run at a good pace.

I have the following situation:

1. I have NHibernate 2.1.2.4000 which yes or yes requires Antlr 3.1.1

2. I did an optimization of the entire web application using minification and bundling techniques with WebGrase using Antlr (>= 3.4.1.9004) The performance increased up to 38.8%. For those who want to learn, here are a couple of links: https://docs.microsoft.com/en-us/aspnet/mvc/overview/performance/bundling-and-minification and https://docs.microsoft.com /en-us/aspnet/core/client-side/bundling-and-minification

3. I have both Antlr Dlls in parallel.

4. When accessing a controller that uses NHibernate , I get the following exception:

An exception of type 'System.IO.FileLoadException' occurred in NHibernate.dll but was not handled in user code

Additional information: Could not load file or assembly 'Antlr3.Runtime, Version=3.1.0.39271, Culture=neutral, PublicKeyToken=3a9cab8f8d22bfb7' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

This error happens because it is referencing the new ANTLR library and what I need is to travel back in time and make use of the old library.

5. I've done binding redirects on it web.configwith no success so far.

Data:

 <Reference Include="antlr.runtime, Version=2.7.7.3, Culture=neutral, PublicKeyToken=d7701e059243744f">
      <SpecificVersion>False</SpecificVersion>
      <HintPath>..\Dependencies\Antlr.3.1.1\lib\antlr.runtime.dll</HintPath>
</Reference>
<Reference Include="Antlr3.Runtime, Version=3.4.1.9004, Culture=neutral, PublicKeyToken=eb42632606e9261f, processorArchitecture=MSIL">
      <HintPath>..\packages\Antlr.3.4.1.9004\lib\Antlr3.Runtime.dll</HintPath>
      <Private>True</Private>
</Reference>
<Reference Include="Antlr3.Utility, Version=0.1.0.39272, Culture=neutral, PublicKeyToken=3a9cab8f8d22bfb7, processorArchitecture=MSIL">
      <SpecificVersion>False</SpecificVersion>
      <HintPath>..\Dependencies\Antlr.3.1.1\lib\Antlr3.Utility.dll</HintPath>
</Reference>
<Reference Include="NHibernate, Version=2.1.2.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4, processorArchitecture=MSIL">
      <SpecificVersion>False</SpecificVersion>
      <HintPath>..\Dependencies\NHibernate.dll</HintPath>
</Reference>

Some of the bindings I tried were:

Using the NHibernate token:

 <dependentAssembly>        
        <assemblyIdentity name="antlr.runtime" publicKeyToken="aa95f207798dfdb4" Culture="neutral" />
        <bindingRedirect oldVersion="3.1.0.39271" newVersion="3.4.1.9004" />
</dependentAssembly>

<dependentAssembly>        
        <assemblyIdentity name="NHibernate" publicKeyToken="aa95f207798dfdb4" Culture="neutral" />
        <bindingRedirect oldVersion="3.1.0.39271" newVersion="3.4.1.9004" />
</dependentAssembly>

Using Antlr's token (and traveling back in time):

<dependentAssembly>        
        <assemblyIdentity name="NHibernate" publicKeyToken="d7701e059243744f" Culture="neutral" />
        <bindingRedirect oldVersion="3.4.1.9004" newVersion="3.1.1.0" />
</dependentAssembly>

I will continue looking for a solution in the meantime, when I find it I share it :D

I've recently been looking for a way to POST a URL using RestSharp and read the result, does anyone have an idea how to achieve this?

Recently I was curious and I would like your support to solve this question: ReactJSComponents are created in components, and so far, everything is fine, however when the logic to be developed is added... How to make a good depuración? And when it needs to be done pruebas unitarias, how to test it?

Here an example ofReactJS

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8" />
    <title>Hello React!</title>
    <script src="build/react.js"></script>
    <script src="build/react-dom.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/babel-core/5.8.23/browser.min.js"></script>
  </head>
  <body>
  <div id="example"></div>
  <script type="text/babel">
  ReactDOM.render(
    <h1>Hello, world!</h1>,
    document.getElementById('example')
  );
  </script>
  </body>
</html>

I have the following HTML structure with Bootstrap

<div class="row">
    <div class="col-md-9">
     Aqui hay tanto contenido que el scrollbar se va hasta China
    </div>
    <div class="col-md-3">
        <div> 
            Este debe mantenerse flotando a la derecha de manera fija, asi el scroll llegue al piso.
        </div>  
    </div>
</div>

When using position:fixedin divwith the class col-md-3, it goes to the left and is placed on the content of the div col-md-9. I used the Bootstrap affix and it didn't work for me.

good morning, I would like your help to solve this question I have about deploying ASPnet 5 (Core1, CoreCLR) on a subdomain. I have the following:

1. Environment: GNU/Linux Apache MySQL PHP.
2. DNV installed (.net core and mono)
3. Yeoman generator.

By giving it "dnx web", it works for me at http://localhost:5000 I have this app under a folder in a subdomain: http://subdomain.domain.com/aspnet5/fx

How do I make the app work in that production environment? I have been recommended to make a docker container with nginx (+reverse proxy) and this weekend I will see this topic.
