Things to know: Upgrade RAM in your Desktop

Today, I have tried to upgrade RAM on my server and faced some challenges as the server is not recognizing the new RAM, I have added. So I did some googling and found some important and crisp information. So would like to share the same for everyone's convenience. 

The below youtube links are all what you need in order to understand what and how you need to do a RAM upgrade in your desktop machine or a laptop. 

1. Introduction to RAM (Memory) - Video link 
2. Features and types of Memory - Video link
3. Upgrading Memory in your Desktop - Video link 
4. Upgrading Memory to Desktop and a Laptop - Video link

Like mentioned in the video links, the sites and tools you must use before you make the decision of either buying or upgrading your RAM are:

Hope this helps. Good luck. 

What are Containers in AX 2012?

In X++, container is one of the primitive (value) types. A container can contain an ordered sequence of primitive values or other containers.

A container can be used as one of the column types that you can select when you add a new column to a table in AOT. Thereby, it can be stored in the database. Container is not a class. Containers can be said to be similar to an arary or List/stack classes. But with Containers you can never change size or content of an existing container.

Another interesting thing about containers is that they are immutable. Even though few X++ statements in the System code appear to modify a container, they are actually internally building a new container and copying values as necessary. Even an assignment of a container to another container variable creates a new copy of the container. Because of all this, usage of containers are said to have performance implications.

The X++ function conPeek returns an anytype type. The flexibility of anytype makes container a good way to store values of different types together. This makes it easier to read the values from a container when you do not know what type each value is. An anytype can be assigned to any X++ value type, as long as the value can be converted.

Quick summary:
A container is best suited for processes that do not involve excessive modification to the size or contents of the container.
A container is helpful when you must pass a variety of value types between the client and server tiers.
A container is a poor choice when you intend to repeatedly add to a list in a loop.
