WHY USE A VIRTUAL MACHINE SETUP?

Flexible work: Today, a growing application of VMs helps companies arrange flexible and remote work environments. When the software itself is the workspace, then where the computer or device is physically located doesn’t matter nearly as much. This allows everyone to collaborate in similar spaces no matter where they are or what machine they are using — or to switch to a different mode without the need to change computers. Storage space also isn’t very important, because most of the VM activity is managed behind the scenes by central servers.

 Security: Virtual machines are used in two interesting security tactics. First, they are used to study ransomware, viruses, and other types of nasty attacks in a relatively safe environment. In this case, the malware usually thinks that VM is a real computer and starts to attack it, while white hat security experts can study how it operates and find weaknesses without endangering their “real” computers. Second, organizations can use VMs to help protect from device-based attacks, such as attacks using a smartphone OS framework.

 Experiments: One of the oldest uses of virtual machines is to test new apps or coding changes in a safe environment that won’t crash the computer if something goes wrong. This type of VM can be very simple and inexpensive — and is commonly used by developers to to test apps for different operating systems.

 Data management: Virtualization allows organizations to centralize data, change how they use servers or how many servers they use, and refine their hardware purchase strategy.

 Special cases: In some cases, a VM setup can allow people to run software that they would not otherwise be able to run. For example, maybe you want to run an app that only works on an older version of the OS you are using (say a Windows 8 app on Windows 10) — a VM can allow you to do that without removing all your updates. Or you can use a VM to run an entirely different OS as needed for specific apps. This may be particularly useful for students who don’t have the right OS for classwork software, or similar cases.

.NET Core vs .NET Framework: How to Pick a .NET Runtime for an Application

Image
Is  .NET Core  the next big thing? We’ve been toying with it for a while now, and we tend to think that it is. In fact, we predict that there will be a  huge demand  for developers skilled in this technology in 2018-2019. But how does it differ from the .NET Framework, and what do you need to know to use them effectively? In this post, we’ll explain the main differences and offer some guidance on how to make the best use of each. Historically, the .NET Framework has only worked on Windows devices. The Xamarin and Mono projects worked to bring .NET to mobile devices, macOS, and Linux. .NET Core provides a standard base library that can now be used across Windows, Linux, macOS, and mobile devices (via Xamarin). There are four major components of .NET architecture: Common language specification  (CLS) defines how objects are implemented so they work everywhere .NET works. CLS is a subset of Common Type System (CTS) — which sets a common way to describe all types. Framework class

multi color initial(Avatars) if img not available in Angular it's work angular 2,4+ all versions

Today I will show two methods apply background-color in initial Method 1: here I will show dynamic colors using random calls step 1: create a component and define color array list in .ts file public circleColor: string; colors = [ '#6930c3 ', // French Violet '#0096c7', // Blue green '#FFFF5C', // Laser lemon '#FF3366', // Radical red '#F49F0A', // Tagrine '#25a550', // Green '#03312E', // Rich black ]; step 2: ngOnInit() { const randomIndex = Math.floor(Math.random() * Math.floor(this.colors.length)); this.circleColor = this.colors[randomIndex]; } step 3: In .html <div class="circle" [ngStyle]="{'background-color': circleColor }"> // change color // <img *ngIf="!showInitials && showComponent" src="{{photoUrl}}" onerror="showInitials " class="initials">{{ initials }}
