install Ubuntu OS in windows 10 with simple steps

How to install Ubuntu OS  in Windows 10 with a new version

                      Ubuntu OS with VirtualBox

BY: DIBYANSHOO PANDEY

Yes, so Let's start with Windows 10 install Ubuntu in virtual box, Before starting the installation of the virtual box and Ubuntu, I want to describe the key points.

• Getting started with Ubuntu 16 in VirtualBox
• VirtualBox installation
• Create an Ubuntu virtual machine
• Install Ubuntu

This article will describe how to install Ubuntu on Windows 10 using VirtualBox.

Getting started with Ubuntu 16 in VirtualBox

Today I will be installing VirtualBox on Windows 10  64-bit/32-bit, then creating a new virtual machine on the virtual box to run Ubuntu 16.04.1 (the guest). For those running Windows 10 edition, this probably works for you.so no need to pressurize work properly and follow all steps 

VirtualBox installation

1. First, we need to download VirtualBox from https://www.virtualbox.org. I’ve downloaded VirtualBox 5.1.14 already on my desktop.
2. Run the Exe file as administrator and follow the prompts to complete the installation. We don’t really need to change anything for our purposes and can accept the defaults. Before completing the wizard you will get a warning that the network connection will temporarily be interrupted, so make sure you’re not doing anything that would be impacted, like being half-way through downloading a 16GB file that can’t be resumed.
   

Create an Ubuntu virtual machine

1. Download the latest Ubuntu release from https://www.ubuntu.com/download/desktop. I’ve downloaded Ubuntu 16.04.1
2. Open VirtualBox and click New
   
3. Type the Name for the virtual machine, like Ubuntu 16. VirtualBox will try to predict the Type and Version based on the name you enter. Otherwise, select:
   
   • Type: Linux
   • Version: Ubuntu (64-bit)
   and click Next.
   
4. Next, we need to specify how much memory to allocate the virtual machine. According to the Ubuntu system requirements we need 2GB, but I’d recommend more if your host can handle it. Basically the higher you can set the memory without severely impacting your host machine, the better the performance of the guest machine. If you’re not sure, stick with 2GB.
   
5. On the Hardware, screen select Create a virtual hard disk now and click Create
6. Accept the default option VDI for Hard disk file type (or change it if you wish…) and click Next
7. Next, we are prompted for Storage on the physical hard disk. The options are Dynamically allocated and Fixed size. We’ll use the default of Dynamically allocated. Click Next
   
8. Choose the hard disk size and storage location. The Ubuntu system requirements recommend 25GB. Remember, we choose Dynamically allocated as our storage option in the last step, so we won’t consume all this disk space immediately. Rather, VirtualBox will allocate it as required, up to the maximum 25GB we specified. Click Create
9. The wizard will finish and we are returned to the main VirtualBox window. Click Settings
   
10. In the left pane select Storage, then in the right select the CD icon with the word Empty beside it.
    
11. Under Attributes click the CD icon (highlighted in the screenshot above) and select Choose Virtual Optical Disk File and browse to the downloaded file ubuntu-16.04.1-desktop-amd64.iso
    
12. Click OK to close the Settings dialog window. The virtual machine should now be ready to start.

Install Ubuntu

In VirtualBox, your VM should be showing as Powered Off, and the optical drive configured to point to the Ubuntu ISO file we downloaded previously.
1. In VirtualBox, select the virtual machine Ubuntu 16 and click Start. VirtualBox will launch a new window with the VM and boot from the iso.
   
2. Click Install Ubuntu
   
3. Select Download updates while installing Ubuntu and click Continue
4. On the next screen accept the default of Erase disk and install Ubuntu and click Install Now
   
5. You will be prompted with a warning saying the changes will be written to disk. Click Continue
   
6. Select your timezone and click Continue
7. Select your keyboard layout. I accepted the default of English (US) and click Continue
8. Enter a username and password, then click Continue
   
9. The Ubuntu installation may take several minutes to run, so have another coffee.
   
10. When the installation is finished you will be prompted to restart. Save and close anything else you may have open and click Restart Now
    
11. Now when the vm reboots you may see this message.
    
    From the menu select Machine > Settings.
    Navigate back into the Storage settings where we previously selected the file. If the Ubuntu iso file is still there, remove it. Otherwise, close the Settings window and in the VM press Enter to proceed.
12. If all went well the VM should boot to the Ubuntu login screen. Enter your password to continue.
    
Ubuntu should run normally in the VirtualBox environment. If everything is far too small, you can adjust the ‘zoom’ by selecting View > Scale Factor > 200%.
I suggest you, If your PC RAM is less than 8GB, so you no need to install Ubuntu in the virtual machine, you can dual boot your PC with Ubuntu.
Have fun!

How to write code of swap two numbers without using third variable in python

How to write code for swap two numbers without using third variable in python

                           

                              Python problem no:1

BY: DIBYANSHOO PANDEY 

              

                  Python is a simple and object-oriented programming language, there is very simple to define the variable of the problem and describe the points of the problem, and easy to write the algorithm of problem.

Given two-variable a1 and a2. The task is to swap the values of both the variable without using the third variable.

Let's take the two variables and swap both numbers.

For Example: 

                        

                    X: 10

                     Y: 20

After swapping X and Y, We get :

                    X: 20

                    Y: 10

3. JavaScript

JavaScript is a mini object-oriented scripting language that is lightweight and cross-platform. JavaScript is not a programming language, it is a framework language, but it is a translated language.which has translated the syntax of the program. The JavaScript Translator of the backend development  (embedded in the browser) is responsible for translating the JavaScript code for the web browser.

JavaScript yes. Know as the backbone of full-stack development that means (Mean stack development ), it's also known for frontend development in web development. It is a feature-rich mini object-oriented scripting language. 

JavaScript started as a simple and client-side scripting language. Now a day major frameworks are useful for both front-end as well as backend and web Scripting. This is the most useful language which is used for frontend and web Scripting.
