After installing Rocky Linux 8 on VirtualBox, It could be observed that networking is not coming up automatically. You can verify that once you click on the right corner of the screen where it shows the battery and sound icon. It should display wired off something like the below picture.

Updates and releases of CentOS Linux 8 were discontinued on December 31, 2021, and will be discontinued for CentOS Linux 7 on June 30, 2024, and if you are working on a CentOs-based system and exploring other RedHat family-based OS then you have one of the options to try Rocky
hyper-v
You created a virtual machine on Hyper-V but due to some reason, you want to move to VirtualBox. Hyper-V supports VHDX file format whereas VirtualBox supports VDI and VHD. So the first thing we have to export the Virtual Machine on Hyper-V which will be in VHDX format then convert

Linux is widely popular in the developer or sysadmin community. These are a few commands which are quite famous among developers and admins. Whenever in doubt, always try to use ‘–help’ command option of the command. grep – grep command is used when you want to search a string in a

What is the callback function? A callback function is a function you provide to another function, allowing it to be called by another function. Callbacks are most easily described in terms of the telephone system. A function call is analogous to calling someone on a telephone, asking her a question,

The Array is a contiguous data structure. It enables you to store data in contiguous form. It is an indexed collection of a fixed number of homogenous type data. Let’s assume, you want to store 5 numbers of colors in variables. Instead of storing them in each variable, you
C
List data structure brings the non-contiguous implementation of data, unlike array which is contiguous in nature. Usually, Array’s size is static in nature which will wastage of memory if it is not being used by the program. In the case of List, one can store the data in a
C
A circular Queue is the optimized solution of a normal queue. In this particular approach, we can make sure all the memory space of the queue is being utilized. Once the rear reaches the last position and the dequeue operation is performed, updating the rear value will allow us to
C
Queue data structure enables you to use FIFO [ First IN First OUT ] approach. Whatever data comes first goes first. It is also called LILO [ Last IN Last OUT ]. For I/O, it provides you two functions. 1. Enqueue [ To insert data into queue ] 2. Dequeue [ To delete the data from
C
Stack data structure enables you to use LIFO [ Last IN first OUT ] approach. Whatever data comes first goes last. It also called FILO [ First IN Last OUT ]. For I/O, it provides you two functions. 1. Push [ To insert data into stack ] 2. Pop [ To delete the data from the
C
For every programmer, it is really important to understand the data structure and which one is more suitable for a solution. There could be multiple ways to solve the problem but once you look into the larger scale one can start finding which solution is most suitable for the problem.
JIRA
Agile is getting popular so as JIRA and other Atlassian tools. One should know JIRA has its flaws and to be honest there are many. This post is for JIRA Server. JIRA cloud does provide some of the features as inbuild. Basic: 1. JIRA is good but there are things
