// Video can be scaled down using `-vf scale=-1:720`, where 720 is the desired

				I have <em>very</em> fond memories of this computer. This was the computer I used for <i>FIRST</i> Robotics back in high school, and the computer we used to drive the robot at the world championships in 2013 and 2014.
			</p>
			<p>
				That doesn't mean it's fast, of course. You can see that it is very sluggish to do many normal tasks, like typing into a Word document.
			</p>
			<p>
				Still, exploring this computer brings back a lot of memories, and funny enough, allows me to show off a lot of different applications. I found old Blender models on here, an old platforming game in Unity that I barely remember, a video called "OBS Test.mp4" on the desktop, and even a definitely legal copy of Counter-Strike 1.6.
			</p>
			<p>
				Naturally, because it's running Windows 7, I was unable to shut it down without running Windows Update. I had to forcibly kill it.

				This machine was originally used as a workstation at Rutgers University, where it was connected to a NetWare network and used as a fax server at some point. It's hard drive was replaced from one of the stock Maxtor drives to a DEC harddrive that appears to have been pulled out of a VAX.

				It then made its way to an observatory out on Long Island, and was then used to process radio telemetry data as well as light web surfing throughout the 90s before being retired. It was powered on in 2004 and 2005.

				This is the iPod Touch I got when I was 13. It was my first major
				tech purchase and an early device in the iOS lineup. When I
				purchased this I think it was running iOS 3; at this point it has
				iOS 5. I was pleased to see that the battery still holds a charge
				quite well, and it consistently runs at about 30 to 60 frames per
				second.
			</p>
			<p>
				In the video you can see several built-in apps. Media playback
				still works great, and scrubbing around in songs is instantaneous.
				App switching works well. The calculator launches instantly (as
				you would hope). I was shocked to see that the old Google Maps app
				still works - apparently they have kept their old tile-based map
				servers online. It even gave me public transit directions.
			</p>
			<p>
				Overall, I would say this device feels only a hair slower than my
				current iPhone.
