Linux System Call `fork()` in Rust

As we know, System calls provide an interface to the services that are available by the operating system. It is a mechanism in which a computer program requests a service from the kernel of the OS.

In this blog, I will cover fork() system call. fork() is used to create a new process by duplicating the calling process. The new process is referred to as the child process. The calling process is referred to as the parent process. Both child and parent process have their unique process id. The child’s parent process id is same as parent process id.

In this blog, I will show how we can use fork() in Rust. Add [nix](https://crates.io/crates/nix) in cargo.toml. This dependency provides Rust friendly bindings to *nix APIs.

System Databases in SQL Server

Introduction

In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

System Database

Fig. 1 System Databases

There are five system databases, these databases are created while installing SQL Server.

  • Master
  • Model
  • MSDB
  • Tempdb
  • Resource
Master
  • This database contains all the System level Information in SQL Server. The Information in form of Meta data.
  • Because of this master database, we are able to access the SQL Server (On premise SQL Server)
Model
  • This database is used as a template for new databases.
  • Whenever a new database is created, initially a copy of model database is what created as new database.
MSDB
  • This database is where a service called SQL Server Agent stores its data.
  • SQL server Agent is in charge of automation, which includes entities such as jobs, schedules, and alerts.
TempDB
  • The Tempdb is where SQL Server stores temporary data such as work tables, sort space, row versioning information and etc.
  • User can create their own version of temporary tables and those are stored in Tempdb.
  • But this database is destroyed and recreated every time when we restart the instance of SQL Server.
Resource
  • The resource database is a hidden, read only database that holds the definitions of all system objects.
  • When we query system object in a database, they appear to reside in the sys schema of the local database, but in actually their definitions reside in the resource db.

How I Switched from Windows 10 to Linux Mint

This article is all about my journey on switching from Windows 10 to Linux Mint 20, how I got easily adapted to the Linux environment, and some resources that helped me to set up a perfect Desktop environment.

Uncertainty

Ok, now I have decided to switch to Linux but here comes the first question. Which distro will satisfy my needs both in terms of GUI and other aspects? Linux is not something new to me since I have been working with RHEL based distros in my work for the past 4 years with the command-line.

I know RHEL based distros are good for enterprises but not for personalized desktop environments, at least that’s what I am thinking till now. So I started my research to find the distro that should be easy for me to use and at the same time should have good community support if in case I ran into some problem. Among many Linux distros, I drilled down my list to 4 flavors.

Before deciding the Distro it is necessary you formulate the list of tools/programs or packages needed and check if the distro you choose provides all those features.

For me, I use Linux for two main purposes: one is for my professional development work, writing articles, and second for my personal use like Video editing and Movies. Most of the popular software are created to be compatible with Windows, macOS, and Linux like Sublime TextVSCodeVLC Media PlayerFirefox/Chromium browser. Other than these software, cloud-based services make our life easy Like Microsoft Office 365 or G Suite.
