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.
