Many distinctive Linux adaptations, otherwise called appropriations, are accessible today. Each is normally customized for particular target frameworks, for example, servers, work areas, cell phones or implanted gadgets.

System Databases in SQL Server


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
  • 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)
  • 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.
  • 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.
  • 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.
  • 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.

An Overview of Operating Systems: Mac vs. GNU/Linux vs. Windows

1 - Windows
Usually when we buy a system, the default OS is Windows. Many times I saw many people who say that Windows is easy. Let me better understand what they mean!
2 - GNU/Linux
There is a big thing in the GNU/Linux world called freedom and diversity. Torvalds first wrote Linux and then merged with GNU kernels, something Stallman was working on, and later became GNU/Linux. It can be said that everything runs on GNU/Linux! From car, etc. to computers and… 
3 - Mac
But the phrase “Expensive and limited” does not necessarily mean bad… A Gmail app, a web app, a terminal, and other apps, and a fairly clean desktop (which Apple found works for people). For example, if you want a flower to be on top of the desktop, there is one way: you go to Mac and beg them to put flowers on the desktop.

Ternary operator in Python?

  1. Ternary Operator in Python

What is a ternary operator: The ternary operator is a conditional expression that means this is a comparison operator and results come on a true or false condition and it is the shortest way to writing an if-else statement. It is a condition in a single line replacing the multiline if-else code.

syntax : condition ? value_if_true : value_if_false

condition: A boolean expression evaluates true or false

value_if_true: a value to be assigned if the expression is evaluated to true.

value_if_false: A value to be assigned if the expression is evaluated to false.

How to use ternary operator in python here are some examples of Python ternary operator if-else.

Brief description of examples we have to take two variables a and b. The value of a is 10 and b is 20. find the minimum number using a ternary operator with one line of code. ( **min = a if a < b else b ) **. if a less than b then print a otherwise print b and second examples are the same as first and the third example is check number is even or odd.

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.


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.
