Increasing the screen size of Ubuntu on the Oracle VirtualBox


When you install the Ubuntu on Virtualbox and if it doesn't fit the full screen, you can run below commands on the terminal to fix the issue:


Open the terminal (Ctrl+Alt+T) and type below and enter :


1) $ sudo apt-get install virtualbox-guest-dkms
2) $ sudo apt-get install virtualbox-guest-utils
3) $ sudo apt-get install virtualbox-guest-x11



This will increase the Ubuntu screen size on the Virtualbox.



If the third one i.e. "virtualbox-guest-x11" does not get installed due to some dependency reasons like libcheese-gtk23 or libcheese7, you can run following commands alternatively on the terminal :



$ sudo apt-get remove libcheese-gtk23
$ sudo apt-get install xserver-xorg-core
$ sudo apt-get install -f virtualbox-guest-x11



These command will increase the Ubuntu screen resolutions on the Virtualbox. 

It works, cheers !!

Spring Cloud vs AWS/GCP/Azure Cloud - In the realm of Distributed Systems Development

The Scalability and High-Availability have become defacto standards for Distributed Systems development. The traditional applications are moving fast from the On-Prem model to the Cloud. With such requirements, it has become imperative to build an application with robust APIs or Cloud Services having fault-tolerant and graceful fallback functionality. Spring framework has emerged as a full-fledged, robust, feature-rich and mature ecosystem over time. It has been equipped with lots of features for rapid development. Spring Boot dominates the Cloud Native Software development. With the introduction of Spring Boot, the Microservices development has catapulted to a whole new level as it brings all sorts of dependencies in one place. Spring Cloud is an umbrella project under the Spring ecosystem. It consists of many sub-projects to build a robust distributed system. It was primarily developed by Netflix and open-sourced as part of Netflix OSS to create resilient, fault-tolerant and s...

In order to fix the error "Program "make" not found in PATH in Eclipse", follow below steps: Right Click on the Project -> Properties -> C/C++ Build ->Environment Check PATH, if it has C:\cygwin64\bin in the path or not.

Create the Vsix package from a class library

A project that was created as a class library that contains numerous controls that can be used in windows forms applications. In order to create an installation package (*.vsix) that will embed these controls into the visual studio toolbox window. The controls are visible in the toolbox window when being in the solution that has this project within itself. I have created a vsix project and referenced the component project's dll as a Microsoft.VisualStudio.Assembly asset. The VS2017 build process creates the vsix file that I need. When I run it on a system with a fresh VS installation, it goes through the install process with no problems, but the components don't show up in the toolbox. When I try to register the asset as a Microsoft.VisualStudio.ToolboxControl, I get the error 'The target "PkgdefProjectOutputGroup" does not exist in the project.  To reslolve the below error which comes while adding reference of DLL application to VSIX project for Visual ...
