8 min readUnit testing in Erlang is a crucial aspect of software development. It involves testing each individual component or unit of code in isolation to ensure that it functions correctly. Here are the key steps involved in performing unit testing in Erlang:Start by creating a separate module for each unit of code that needs to be tested. These modules should contain the functions or logic that need to be tested.

9 min readImplementing distributed systems in Erlang involves designing and structuring the application to run on multiple nodes, enabling the system to handle large-scale computational tasks with fault tolerance. Erlang provides built-in primitives and libraries for creating distributed systems efficiently. Here are the key aspects of implementing distributed systems in Erlang:Node Communication: Erlang nodes can communicate with each other using a unique node name.

4 min readETS (Erlang Term Storage) is a mechanism in the Erlang programming language that allows for efficient storage and retrieval of data. It is primarily used for in-memory storage within an Erlang application.To use ETS for data storage, you first need to create a table using the ets:new/2 function. This function takes two arguments: a table name (an atom) and a set of options (a list of key-value pairs).

8 min readTo merge XML files into one, you can follow these steps:Understand the XML structure: Familiarize yourself with the XML structure of the files you want to merge. Identify common elements that need to be merged or combined. Open the XML files: Use a text editor or an XML editor to open the XML files you want to merge. Create a new XML file: Create a new XML file that will contain the merged content. This file will be the final result of the merge.

5 min readIn Erlang, file input/output (I/O) operations are handled using built-in functions and modules that provide convenient and efficient ways to read from and write to files. Here's an overview of how to handle file I/O in Erlang:Reading from a File:To read from a file, first, open the file using the file:open/2 function. This function takes two arguments: the file name and the read mode.Once the file is open, you can use various functions to read data from it.

7 min readTo implement a simple server in Erlang, you can follow the steps below:Start by creating a new Erlang module. In the module, define the server behavior using the gen_server behavior provided by the OTP (Open Telecom Platform) library. This behavior abstracts away the complexities of writing a server and provides a structured way to handle server events and requests. Implement the callback functions required by the gen_server behavior.

7 min readIn Erlang, modules are used to organize and encapsulate related functions, types, and other code entities. Here is some information on creating and using modules in Erlang:Creating a Module: A module is defined in a file with the same name as the module and the ".erl" file extension. For example, a module named "my_module" should be defined in a file named "my_module.erl". At the beginning of the module file, use the "-module(ModuleName).
