To login to the Azure account using Azure CLI, we need to use the az login command. Once you type the az login command, it will prompt for the Azure portal login console.If you need to log in with the device authentication code in the browser, you need to use the parameter –use-device-code.PS C:\> az login --use-device-code To sign in, use a web browser to open the page https://microsoft.com/devicelogin and enter the code ‘DeviceCode’ to authenticate.You need to open a website https://microsoft.com/devicelogin/ and have to enter a code. If you are not already connected with the Microsoft Azure portal, you ...
Read MoreHow to get the Application security groups of the Azure VM using PowerShell?
To get the Application security groups of the Azure VM using PowerShell, we need to first get the Network Interface of the Azure VM.The below command will retrieve the NIC name of the Azure VM.PS C:\> $vm = Get-AzVM -Name TestVM $nic = (($vm.NetworkProfile.NetworkInterfaces.id).Split('/'))[-1]Once we have the NIC name, we can use the Get-AzNetworkInterface command to retrieve the NIC information and the Security group.The below command will retrieve the application security group names using PowerShell.PS C:\> $nicsettings = Get-AzNetworkInterface -Name $nic $nicsettings.IpConfigurations.ApplicationSecurityGroups

For example, we need all the files that are ...
Read MoreElectric Power and Efficiency of Electric Device
Power or Electric PowerThe rate at which work is done in an electric circuit is called as electric power. In other word, the work done per unit time is termed as electric power. It is denoted p or P.Formula and Unit of PowerWhen voltage is applied across a resistor, it causes current to flow through it. Therefore, work is being done in moving the electrons through the resistor in a unit time is called the electric power.Referring the above figure, $$\mathrm{V=\frac{work}{Q}}$$$$\mathrm{\Rightarrow work(W)=VQ=VIt}$$As, the power is defined as work done per unit time i.e.$$\mathrm{Power(P)=\frac{work\:done\:in\:electric\:circuit(W)}{Time(t)}=\frac{VIt}{t}}$$$$\mathrm{(∵V=IR\:or\:I=\frac{V}{R})}$$$$\mathrm{∴P=VI=I^2R=\frac{V^2}{R}}$$The above three formulae are equally valid for ...
Read MoreWhat is Requirement Traceability Matrix?
Introduction to Requirement Traceability MatrixA traceability matrix is a table-style document that is used to track requirements in the development of software applications. It can be used to trace backwards (from Coding to requirement) as well as forwards (from Requirements to Design or Coding). Requirement Traceability Matrix (RTM) or Cross Reference Matrix are other names for it (CRM).It is produced prior to the test execution process to ensure that all requirements are addressed in the form of a Test case, ensuring that no testing is missed. We connect all of the requirements to their associated test cases in the RTM ...
Read MoreGet contents of a Tkinter Entry widget
An Entry widget is a basic one-line character widget that supports only single-line text input. An Entry widget can be defined by initializing the Entry(parent, width) constructor.To validate the Entry widget, we can use the get() method which results in the character entered in the Entry widget.Let us define an Entry widget that accepts single-line text input, and we will print the character that is input in the Entry widget.Example#Import the required Libraries from tkinter import * from tkinter import ttk #Create an instance of Tkinter frame win = Tk() #Set the geometry of Tkinter frame win.geometry("750x250") def get_content(): ...
Read MoreSave File Dialog Box in Tkinter
We often use Open and Save Dialog. They are common across many applications and we already know how these dialogs work and behave. For instance, if we click on open, it will open a dialog to traverse the location of the file. Similarly, we have the Save Dialog.We can create these dialogs using Python tkFileDialog package. In order to work with the package, we have to import this in our environment.Type the following command to import the tkFileDialog package in the notebook, from tkinter.filedialog import asksaveasfileExampleIn this example, we will create an application that will save the file using the ...
