The PIPE in python is used to send or receive data from a program that is running as a subprocess in python. To do this, we can use a combination of pipe which is basically creating the pipe, a fork is used to create the subprocess in the program, dup2 is used to force the subprocess to use the pipe as a standard input and output channel, and lastly, exec is used to execute or run the new program. How to use Python Subprocess with Pipes is explained in this article.

Subprocess is a python module that is used to run new codes by creating new processes. It allows the user to create a new application within the currently executing python program. When the user wants to execute an external program from a C or C++ program or any external program from a git repository, the python subprocess can merge those programs. How to use Python Subprocess Check_output method is explained in this article.

S3 (simple storage service) is the storage service provided by AWS and stores data in S3 buckets. By default, all the S3 buckets are private and can not be accessed publicly over the internet. Only the AWS user with specific permissions can access the objects inside the bucket. There are two types of permissions in an S3 bucket. How to configure S3 bucket permissions on AWS is explained in this article.

fcntl is abbreviated as 'file' control. It means it is based on the file handling process. The fcntl is a system call. It allows the program to place a read or a write lock. This function can be used to amend the file properties that are either opened already or can be opened through any action applied to it. It is a versatile function and is used to modify files in many ways like open, read and write, etc. How to use the fcntl function in C is explained in this article.

C language comes up with many libraries used for specific purposes. One of those libraries is the “POSIX” library of C that is specifically for POSIX systems. The POSIX library can let you make threads, get their IDs, and do many things. One of those functions is the “pthread_self()” function that is specially designed to get the ID of the created new thread. How to use the Pthread_self function in C is explained in this article.

Threading is a concept used in programming as well. C language comes up with an API named “POSIX” to allow using threads of different purposes used within our piece of code. One of these threads is the “pthread_detach()” function used to identify or specify a thread as disconnected completely. Also, it will make sure to release all the resources used by that particular thread. How to use Pthread_detach function in C is explained in this article.

The C language comes up with the concept of threads and utilizes the POSIX thread library to do multi-threading, create multiple threads, and use them simultaneously. One of these threads is “pthread_create” which creates a new thread or function to perform some specific task. How to use pthread_create function in C is explained in this article.

If we start using many arguments and try to maintain the correct order and number of arguments, it will do a jumble puzzle for the user. To avoid such a hurdle, we will use different “options”. We can use multiple arguments and use them as options in multiple orders. The usage of the getopt function is discussed in this article.

AWS EC2 can be divided into different types based on launch methods. Different launch types can be used to launch the EC2 instance based on workload. Most AWS Architects use on-demand instances, the costliest launch type of EC2 instances. Depending upon the usage, by choosing the correct launch type, the cost on EC2 instances can be reduced up to 90%. Different EC2 instance launch types on AWS are explained in this article.

The malloc function is used in the dynamic memory allocation and it can also be used to store values in the array. The array is used to store multiple values of the same data type in a single array. In this article, we have learned how to declare and use the array using the malloc() function. The dynamic memory allocation approach is recommended when you want to change the size of an array during the execution of the program.

The COPY statement in Postgres allows you to copy the data from any file in your local system to the table or from table to any file. This article guides you to copy the content from a file in your local drive to a Postgres table. A CSV file is created and appended with some data separated by comma (,). These comma's separate one column from another and thus can be imported to the table of a Postgres. You can copy the whole CSV file at once or you have the option to import only a few columns to the table.

The selection sort algorithm sorts the list of numbers by finding the smallest number from the unsorted list and moving it in the sorted list. Selection sort divides the actual list into two lists, one for sorted numbers while the second list is for the remaining unsorted numbers. This article is a detailed guide on Selection Sort in JavaScript. A comprehensive explanation of selection sort and implementation of it in JavaScript are also provided.
