Mac OS X 10.11 El Capitan protects system files and processes with a new feature named System Integrity Protection. SIP is a kernel-level feature that limits what the “root” account can do.
User accounts can be assigned to one or more groups on Linux. You can configure file permissions and other privileges by group. For example, on Ubuntu, only users in the sudo group can use the sudo command to gain elevated permissions.
Parallels is easily the best virtualization software on the Mac, and earlier this year, they quietly added a new app called Parallels Desktop Lite to the Mac App Store—and unlike its cousin, it’s free to download. The catch: if you want to use Windows virtual machines, you’re going to have to pay for a $60 a year for a subscription.
Modern operating systems offer weather information out-of-the-box. There’s Windows 10’s weather app, and the Notification Center on macOS. But Ubuntu doesn’t come with anything like this.
All web browsers remember a list of the web pages you’ve visited. You can delete this list at any time, clearing your browsing history and erasing the tracks stored on your computer, smartphone, or tablet. Each browser has its own separate history, so you’ll need to clear the history in multiple places if you’ve used more than one browser.
Nintendo is apparently allergic to money. After creating an instant and profitable hit with the NES Classic, the company decided to end production of the cheap little emulation machine just a few months after its introduction. No matter: tech savvy Nintendo fans who couldn’t get a hold of one (or didn’t want to line the pockets of scalpers) have other options.
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.

Google released an Android version of Chrome in 2012, and have never bothered to give it a fullscreen mode. If you’re tired of waiting on your favorite Android app to offer fullscreen, there’s a way to do it yourself with Immersive Mode.
The Windows 10 Creators Update—codenamed Redstone 2—will begin rolling out on April 11, 2017. Like other updates to Windows 10, it’s free, and includes a host of new features. It will be rolled out slowly like the Anniversary Update, so it will be a few months before Microsoft offers it to everyone.
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.
Some PDFs are encrypted with a password, which you’ll need to enter each time you want to view the document. You can remove the password to save yourself some inconvenience if you’re keeping the PDF in a secure location.
The vim text editor, a standard tool included on Linux and macOS, can quickly encrypt text files with a password. It’s faster and more convenient than encrypting a text file with a separate utility. Here’s how to set it up.
When you hook a game controller up to your PC—whether it’s an Xbox controller, PlayStation controller, Steam controller, or something else—you can remap the buttons for individual Steam games however you want. Here’s how.
Plex Media Server is renowned for smooth and intuitive user experience, so you might be a bit surprised if you find yourself puzzled over exactly how to restart your server. Don’t worry, we’ve got you covered.
When you run a command at the bash prompt, it normally prints the output of that command directly to the terminal so you can read it immediately. But bash also allows you to “redirect” the output of any command, saving it to a text file so you can review the output later.
Google Chrome is based on Chromium, an open-source browser project. Anyone can take the Chromium source code and use it to build their own browser, renaming it and changing whatever they like. That’s why there are so many alternative browsers based on Google Chrome—but you don’t necessarily want to use most of them.
Chrome is Chrome, right? You download Google’s browser—now the most popular in the world—and you’d think you have the same experience as everyone else. But like most large software vendors, Google releases Chrome in differing “channels,” testing out features in more unstable versions before they get to the release build that hundreds of millions of people use every day.
It’s ideal to have a dedicated machine for your BitTorrent client, so you can seed 24/7. But it’s energy intensive to leave a full rig powered up and online that often. Enter the Raspberry Pi.
Symbolic links, also known as symlinks, are special files that point to files or directories in other locations on your system. You can think of them like advanced aliases and here’s how to use them in MacOS.
If you live in an apartment complex, you’ve probably noticed more than just the passive-aggressive network IDs that your neighbors use—very likely you’ve had problems with your wireless connections dropping out, or just not being as fast as you’d like. This often has to do with the Wi-Fi channels in your area.
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.
Web Proxy Auto-Discovery (WPAD) gives organizations a way to automatically configure a proxy server on your system. Windows enables this setting by default. Here’s why that’s a problem.
The Windows Command Prompt has a built-in history feature, allowing you to quickly view commands you’ve run in the current session. Even better, the Command Prompt offers quite a few keyboard shortcuts and other tricks for working with your command history.
Whether you’re formatting an internal drive, external drive, or removable drive, Windows gives you the choice of using three different file systems: NTFS, FAT32, and exFAT. The Format dialog in Windows doesn’t explain the difference, so we will.
