Sometimes it’s necessary to grab a still image of what’s happening on your device’s screen—that’s called a screenshot. While this used to be a hassle on Android (many moons ago), all modern handsets include the capability. Here’s how to do it.
Android is very customizable–many of its features are just defaults, and can be swapped out for third-party alternatives without any rooting required. When it comes to iOS, well…not so much.
At this point, smartphones are prolific. We use them for calls, text messages, social networking, photos, quick searches, streaming music, watching videos…the list goes on. But each thing you do drains your battery life, and some apps will even continue to drain your battery in the background when you aren’t using them. A free app called Greenify can fix that.
If there’s an Android application you really love and wish you could run on your computer, now you can: there’s a dead simple way to run Android apps on your PC or Mac without the fuss of moonlighting as an Android developer.
If you’re dual booting Windows and Linux, you’ll probably want to access files on your Linux system from Windows at some point. Linux has built-in support for Windows NTFS partitions, but Windows can’t read Linux partitions without third-party software.
Most people use a graphical file manager to find files in Linux, such as Nautilus in Gnome, Dolphin in KDE, and Thunar in Xfce. However, there are several ways to use the command line to find files in Linux, no matter what desktop manager you use.
Ubuntu and many other Linux distributions use the GRUB2 boot loader. If GRUB2 breaks—for example, if you install Windows after installing Ubuntu, or overwrite your MBR—you won’t be able to boot into Ubuntu.
Virtual machines are demanding beasts, providing virtual hardware and running multiple operating systems on your computer at once. As a result, they can sometimes be a little slow. Here are some tips to help you squeeze every last drop of performance out of your virtual machine, whether you’re using VirtualBox, VMware, Parallels, or something else.
Web browsers you use on your mobile phone or tablet remember your browsing history, just like browsers on your PC or Mac. Anyone who borrows your phone or gets access to it somehow can see which webpages you’ve visited. However, it’s easy to protect yourself.
On occasion you will need to edit the hosts file on your machine. Sometimes because of an attack or prank, and others so that you can simply and freely control access to websites and network traffic.
The bash shell is the standard terminal environment included with most Linux distributions, included with macOS, and available for installation on Windows 10. It remembers the commands you type and stores them in a history file. You probably know a few basics of the bash history, but it’s a lot more powerful than you might realize.
Manufacturers and carriers often load Android phones with their own apps. If you don’t use them, they just clutter your system, or–even worse–drain your battery in the background. Take control of your device and stop the bloatware.
Bash is the default command-line shell on most Linux distributions, from Ubuntu and Debian to Red Hat and Fedora. Bash is also the default shell included with macOS, and you can install a Linux-based bash environment on Windows 10.
When you delete sensitive files from your Dropbox account, you may think you’ve deleted them permanently. However, the files remain in a hidden cache folder on your hard drive for efficiency and emergency purposes that is cleared automatically every three days.
If you’ve tried to install Google Chrome in Ubuntu Linux, you may have noticed that it’s not available in the Ubuntu Software Center. However, it’s easy to download a package file for Google Chrome and install it on your system, and we’ll show you how.
Most Linux distributions include the bash shell by default, but you could also switch to another shell environment. Zsh is a particularly popular alternative, and there are other shells, like ash, dash, fish, and tcsh. But what’s the difference, and why are there so many?
When formatting partitions on a Linux PC, you’ll see a wide variety of file system options. These options don’t need to be overwhelming. If you’re not sure which Linux file system to use, there’s a simple answer.
Android isn’t largely thought of as a desktop operating system, but if you’re curious about how Google’s mobile OS works, running it on a device you already have isn’t a bad idea. This will give you an idea of what to expect on a phone or tablet, all without making a single change to your laptop or desktop since you can easily do this from a flash drive or memory card.
If you need to install Windows or Linux and you don’t have access to a CD/DVD drive, a bootable USB drive is the solution. You can boot to the USB drive, using it to run the OS setup program, just like a CD or DVD.
Want to try out Ubuntu, but not sure where to start? There are lots of ways to try out Ubuntu – you can even install it on Windows and uninstall it from your Control Panel if you don’t like it.
Ubuntu has a number of terminal emulators that you can use, including xterm and the gnome terminal. If you install the kubuntu desktop package you can also use konsole under ubuntu.
Windows 10, 8, 7, and Vista all support symbolic links—also known as symlinks—that point to a file or folder on your system. You can create them using the Command Prompt or a third-party tool called Link Shell Extension.
If you want to download an app not available in your country, connect to a company network on the road, or just stay safe on public Wi-Fi, you’ll need a VPN. Here’s how to connect to a VPN on your Android phone.
A Linux live USB drive is normally a blank slate each time you boot it. You can boot it up, install programs, save files, and change settings. But, as soon as you reboot, all your changes are wiped away and you’re back to a fresh system. This can be useful, but if you want a system that picks up where you left off, you can create a live USB with persistent storage.
A bootable USB drive is the best way to install or try Linux. But most Linux distributions—like Ubuntu—only offer an ISO disc image file for download. You’ll need a third-party tool to turn that ISO file into a bootable USB drive.
