In audio/video parlance, “scrubbing” is the act of fast-forwarding or reversing through the audio track or video to a particular location. Most of the time, the default speed is fine, but if you’re looking for a particular location (especially in a long video), it helps to slow down the scrubbing speed. You can do that easily in Apple apps like Safari and Music, and also in some third-party apps. Here’s how.
When you’re watching a video or listening to a track, you just tap and hold the dot on the location slider, and then drag it left or right to scrub backward or forward.
If you want to change the scrub speed, slide your finger down while holding the dot. The display will change to show the scrub speed. Options include Hi-Speed (the default), Half-Speed, Quarter-Speed, and Fine. You can also slide your finger back up through the options. While still holding the dot, you can then move left and right to scrub at your selected speed.
It takes a bit of practice, since you have to hold the dot the entire time. And, if your thumb is as fat as mine, it will usually obscure the display showing the scrub speed. I find it easier to scrub after pausing, but you can go either way. The implementation is not perfect, but it’s a handy little feature for finding just the spot you’re looking for in that movie.
The command prompt has been around forever, and while it might not be as useful in Windows as one would hope, it’s still a great resource to have at your disposal. Today we’re showing you all of the different ways to open the command prompt. We’re betting you don’t know all of them.
Your Roku can do more than just stream from the web. Use it to watch video files you’ve downloaded or ripped yourself, or even play your personal music collection. You can do this with a USB drive or over the local network.
Cloud storage isn’t just for your own personal files. You can use it to easily share files without any hassle. Share files back-and-forth with your friends and colleagues, or make them available to the entire Internet.
Windows 10’s File Explorer has a new “Quick Access” view. Whenever you open a file browser window, you’ll see a list of “frequent folders” and recent files. This list of folders also replaces the old favorite folders list.
PCs don’t have to be power hogs, but they often are. High-powered desktops with gaming-focused dedicated graphics hardware are the most thirsty for energy, but older PCs are typically less energy-efficient than modern ones.
Windows 10 uses white window title bars by default. This is a big change from Windows 8, which allowed you to pick any color you wanted. But you can give those title bars some color with this quick trick.
A VPN, or Virtual Private Network, allows you to create a secure connection to another network over the Internet. VPNs can be used to access region-restricted websites, shield your browsing activity from prying eyes on public Wi-Fi, and more.
Linux distributions aren’t just the Linux kernel. They all contain other critical software, like the Grub bootloader, Bash shell, GNU shell utilities, daemons, X.org graphical server, a desktop environment, and more.
DOS isn’t widely used anymore, but you wouldn’t know if from reading instructions written by manufacturers for BIOS updates, firmware-updating utilities, and other low-level system tools. They will often require you to boot into DOS and run the utility.
Android has taken huge strides since Android 2.3 Gingerbread, but many devices are still using it. If you can’t upgrade your old device, there are ways to make it feel more modern.
