## Context mapping between contexts that publish and consume events

A Open the host service In domain driven design, this is a great way to represent access to a context through a number of APIs. What is a good way to represent an upstream-downstream relationship where the downstream context consumes events published by upstream?

## onepage checkout – magento 1.9 does not redirect the customer to the success page after a successful order

I have a strange problem with Magento 1.9.
Sometimes after a successful order the customer is not redirected to the success page, this does not happen in all orders, possibly 1 out of 5.
After diagnosing the problem, I found that in

core/Mage/Checkout/controllers/OnepageController.php

It seems that there is no getLastSuccessQuoteId () as shown in the pictures below

I thought it could be because of Redis, but I'm not sure. Has anyone previously had a similar problem or idea how to solve this problem? Thanks a lot 🙂

## Flutterpfeil – Problems with special characters

I get a JSON with the data and set up the screen. I have problems with accents and ç that are not configured. How do I let the application understand the signs?

Text (& # 39; Name: & # 39 ;, Style: Headings),
Text (& # 39; \$ {name_name} & # 39;),
In this case the stage is out of shape

## Exercise: Design a stack

Exercise: Design a stack

A stack is a data structure for storing a list of items in a LIFO
(last in, first out) fashion. Design a class called Stack of Three
Methods.

void Push(object obj)
object Pop()
void Clear()

The Push() The method saves the specified object at the top of the stack. We use
The type "object" here so we can save all objects in the batch.
Remember that the object class is the basis of all classes in .NET
Frame. In this way, all types can be automatically transferred to the object.
Make sure that you consider the scenario to which null is passed
this object. We shouldn't store zero references in the stack. So if
If null is passed to this method, you should throw one
InvalidOperationException. Remember when you code each method, you
should think about all the options and make sure that the method behaves
right in all these marginal cases. That differentiates you from
an "average" programmer.

The Pop() Method removes and returns the object on top of the stack
it. Make sure you consider the scenario we call Pop ().
Method on an empty stack. In this case, this method should trigger one
InvalidOperationException. Remember your classes should always be in
a valid condition and used correctly. If they are abused, they should
Throw exceptions. Here too, thinking of all these marginal cases separates
From an average programmer. The code so written will be more
robust and with fewer errors.

The Clear() Method removes all objects from the stack.

We should be able to use this batch class as follows:

var stack = new Stack();

stack.Push(1);
stack.Push(2);
stack.Push(3);

Console.WriteLine(stack.Pop());
Console.WriteLine(stack.Pop());
Console.WriteLine(stack.Pop());

The edition of this program will be

3
2
1

That was the task assigned to me. My code follows.

using System;

namespace Exercise
{
class Program
{
static void Main()
{
var stack = new Stack();

stack.Push(1);
stack.Push(2);
stack.Push(3);

Console.WriteLine(stack.Pop());
Console.WriteLine(stack.Pop());
Console.WriteLine(stack.Pop());
}
}
}
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;

namespace Exercise
{
internal class Stack : IEnumerable
{
private object _object;
private List
