VirtualBox

Like I've used a Mac most of my life, not really a Windows user.

But if you ever wanted to get any Windows experience as a developer without having to buy a fully new Windows laptop, you could actually set up a virtualization software such as VMware or VirtualBox and then pull in some type of guest operating system, the Windows guest operating system.

And basically, uh, the idea of a virtual machine is that you can have a operating system running inside of a- another operating system, and then it uses the resources, the hardware that your main operating system uses, as if it were native to it, but it's not really native.

It's going...

Andy helped us build a transcoder, like a virtual machine transcoder, and we used Vagrant to build the VMs on people's computers automatically.

So you'd load up this VM, put it in VirtualBox, and then point it at two folders, and you'd put... one file in one folder, and then it would transcode that.

It would spit out a...

You put a DVD ISO in one folder, and it would spit out an MP4 or an MKV in the other

You should have, at a minimum in your home lab, set up some type of virtualization software.

So if you're in Windows, you can run VirtualBox.

You can run VMware's virtualization capabilities.

I'm running Mac OS on my machine, so I can run also VirtualBox.

I tend to run Parallels, which is a commercial virtualization software, but it's really designed for Mac OS.

Find some type of virtualization software.

And broadly speaking, there are two approaches to this.

You have Hypervisors like VirtualBox, which emulate an entire physical computer, and then you have containers like LXC, which take a much lighter approach.

But before you can build either, you have to get the software onto your system.

Right.

How so?

They connect your system directly to highly curated, cryptographically secure repositories maintained by the developers of your operating system.

When you type apt install VirtualBox, you aren't searching the wild web.

Right.

Now, you could-- If you're in Windows, you may be running, uh, a VMware Workstation hypervisor.

Maybe you're running a VirtualBox.

You're r- able to do virtual systems.

So in here, I have things like Windows and Linux and other Windows configurations.

It's everything it does.

So that's where the value is.

That same virtualization capability, and even with running things in VirtualBox, uh, if I go to the top here, I can bring up...

Take this out of full screen so we can do something with it.

And the methodology is very strict about setting up a sandbox.

It requires utilizing a virtualization suite like VMware Workstation or Oracle VirtualBox to create a nested isolated network on a single machine.

Crucial step.

Yeah.

Yeah, that's not wrong.

I mean, MySQL and VirtualBox.

They have to pay.

And so I'm making them pay $2 a month at a time.

This is the front end that we use.

It's from a third party called Vbox.

And that allows you to follow along with the questions today and answer the questions that we have.

In fact, I have a question for you right now that we can try.
