If you’re an Android user, Google is ubiquitous throughout the operating system. You can access Google Now on Tap from pretty much anywhere by long-pressing the home button, jump into Google Now directly from the launcher, or say “OK Google” to use your voice from pretty much anywhere in the OS. But each time you do one of those things, it creates a new search entry in your Google History.
Ubuntu adopted the new version of the Grub boot manager in version 9.10, getting rid of the old problematic menu.lst. Today we look at how to change the boot menu options in Grub2.
This trick is for Linux and SSH users who often log in to remote systems. Having to type the same info over and over again is mind-numbingly repetitive, but using an SSH config file makes the process much more convenient.
This trick should work on all Debian-based Linux distros, including Ubuntu. To get started, type ifconfig into the terminal and hit Enter, take note of the name of the interface that you want to change the settings for.
Modern PCs ship with a feature called “Secure Boot” enabled. This is a platform feature in UEFI, which replaces the traditional PC BIOS. If a PC manufacturer wants to place a “Windows 10” or “Windows 8” logo sticker to their PC, Microsoft requires they enable Secure Boot and follow some guidelines.
Ubuntu has a lot of GUI-based methods for installing applications, but they take some time to search and find. Since the keyboard is usually faster than the mouse, managing your software via the command-line can be a real time-saver.
When you have multiple applications that do the same thing—like browsers, for example—Android will ask you which one you want to use every time, at least until you set one as the default with the “always” action. In the earlier days of the app picker, you’d have to clear defaults for each one before applying another, but things have changed.
ADB, Android Debug Bridge, is a command-line utility included with Google’s Android SDK. ADB can control your device over USB from a computer, copy files back and forth, install and uninstall apps, run shell commands, and more.
Android phones and tablets can fill up quickly as you download apps, add media files like music and movies, and cache data for use offline. Many lower-end devices may only include a few gigabytes of storage, making this even more of a problem.
Android’s notification system is easily one of its most powerful features. But with great power comes great responsibility, and some apps choose to abuse this. If you’re sick of constant notifications from specific apps, here’s how to completely disable them.
If you’re running Linux, then it’s likely that you’ve needed to change some options for your file systems. Getting acquainted with fstab can make the whole process a lot easier, and it’s much easier than you think.
If you’ve been using Linux for some time (and even OS X) you’ll probably have come across a “permissions” error. But what exactly are they, and why are they necessary or useful? Let’s take an inside look.
Phones get stolen or lost everyday. With a plethora of data ripe for identity-theft on it, a lost phone can easily make your blood run cold. Take a deep breath, How-To Geek will talk you through this.
If you’re a Linux user, you’ve probably seen references to both sudo and su. Articles here on How-To Geek and elsewhere instruct Ubuntu users to use sudo and other Linux distributions’ users to use su, but what’s the difference?
If you’re a Linux user, you’ve probably heard that you don’t need to defragment your Linux file systems. You’ll also notice that Linux distributions don’t come with disk-defragmenting utilities. But why is that?
Installing software on Linux involves package managers and software repositories, not downloading and running .exe files from websites like on Windows. If you’re new to Linux, this can seem like a dramatic culture shift.
One of the defining features of Linux and other UNIX-like operating systems is that “everything is a file.” This is an oversimplification, but understanding what it means will help you understand how Linux works.
AppArmor is an important security feature that’s been included by default with Ubuntu since Ubuntu 7.10. However, it runs silently in the background, so you may not be aware of what it is and what it’s doing.
When a Linux system boots, it enters its default runlevel and runs the startup scripts associated with that runlevel. You can also switch between runlevels – for example, there’s a runlevel designed for recovery and maintenance operations.
If you’re a Linux user, you may have seen zombie processes shambling around your processes list. You can’t kill a zombie process because it’s already dead – like an actual zombie.
On Linux, the Root user is equivalent to the Administrator user on Windows. However, while Windows has long had a culture of average users logging in as Administrator, you shouldn’t log in as root on Linux.
Some people think that task killers are important on Android. By closing apps running in the background, you’ll get improved performance and battery life – that’s the idea, anyway. In reality, task killers can reduce your performance and battery life.
The media is full of reports saying Android malware is exploding and that Android users are at risk. Does this mean you should install an antivirus app on your Android phone or tablet?
Geeks often describe programs as being “open source” or “free software.” If you’re wondering exactly what these terms mean and why they matter, read on. (No, “free software” doesn’t just mean that you can download it for free.)
In a world where you can have 3D scenes rendered in real time as your smartphone’s background, plain black wallpapers aren’t the most eye-catching option. However, they can offer battery life improvements over colored wallpapers…on some displays.
