Groups help define the permissions and access your Linux user account has to files, folders, settings, and more. Finding out the groups to which a user account belongs helps give you a better understanding of that user’s access (and troubleshoot when things don’t work right).
Most modern computers are capable of running a 64-bit operating system. But just because a computer supports it doesn’t mean that’s what’s running. Here’s how to tell whether you’re running a 32-bit or 64-bit version of Linux.
This trick should work on all Debian-based Linux distros, including Ubuntu. To get started, type ifconfig at the terminal prompt, and then hit Enter. This command lists all network interfaces on the system, so take note of the name of the interface for which you want to change the IP address.
Computer processors have a massive design flaw, and everyone is scrambling to fix it. Only one of the two security holes can be patched, and the patches will make PCs (and Macs) with Intel chips slower.
Do you ever go to Google Maps on your computer, only to see a blank mother-of-pearl grid? It’s really annoying, and it doesn’t happen for any obvious reason. It’s still possible to use Google Maps when it gets like this—you can use search and find specific addresses—but the core functionality is more or less shot. It looks like this:
Virtual Private Networks (VPNs) are very useful, whether you’re traveling the world or just using public Wi-Fi at a coffee shop in your hometown. But you don’t necessarily have to pay for a VPN service—you could host your own VPN server at home.
If you’re a human person who occasionally engages in commerce, hackers are probably targeting you. This year, resolve to do something about it.
Looking for a bit of PC gaming nostalgia? You could dig those old floppy disks out of your closet…or you could grab the new, improved, open source versions of those games online for free.
It’s finally happening: on February 15, 2018, Google’s Chrome browser will block some ads out-of-the-box, regardless of whether you have a separate ad blocker installed.
Yesterday, fellow How-To Geek writer Eric Ravenscraft recommended a Steam game in our office chat room. It’s all about writing…and also it’s about anime-style schoolgirls and the wooing thereof.
Mozilla was supposed to be different. It brands itself as a non-profit organization dedicated to making the web better, one that cares about user privacy and security. But after this week, I’m starting to wonder if Mozilla really cares about its users the way they claim.
If something sounds too good to be true, it probably is. And Kodi boxes sound way too good to be true, offering unlimited free TV and movies for life after purchasing a single piece of hardware.
Many boxes you plug into your TV, including the Roku, PlayStation 4, Xbox One, and even some smart TVs themselves offer DLNA (“Digital Living Network Alliance”) streaming support. They can stream video files and music over the network from your PC—as long as you set up a DLNA server on the PC first.
TeamViewer is a great free program, whether you want to access your computer from afar or help out friends and relatives with their computer. But its default settings are remarkably insecure, instead favoring ease of use. Here’s how to lock down TeamViewer so you can make use of its features without opening yourself up to attack.
Firefox Quantum‘s interface is still extremely customizable thanks to its userChrome.css file. You can edit this file to hide unwanted menu items, move the tab bar below the navigation toolbar, view multiple rows on your bookmarks toolbar, and do other things that normally wouldn’t be possible.
It’s been a complaint about Chrome for years: “it hogs so much RAM!” And now that Firefox Quantum is here, the fire rages on—some users see less RAM usage than Chrome, while others see similar amounts. And it seems to have a big hand in what browser people are using.
Chromebooks have come a long way since their humble introduction with the CR-48 back in December of 2010, but people still think of them as “just a browser”. The thing is, this platform has grown significantly since then, and that mindset is just outdated.
With Spotify Premium, you get access to higher quality music streaming. By default (and if you’re on the free plan), Spotify streams at 96kbps on mobile and 160kbps on your computer. At these sort of bitrates, you’ll hear a small but noticeable drop in quality compared to a CD.
The idea of a home page has kind of fallen by the wayside with modern browsers, what with their auto-recall tabs and syncing across devices. But it doesn’t help that Chrome, arguably the most popular browser on full desktop operating systems, isn’t entirely clear on exactly what your home page is. This can be especially frustrating if your home page changes without your knowledge.
Sure, Firefox has become more like Chrome in a few ways, but it’s still more powerful and customizable than Chrome is—which are integral to Firefox’s DNA.
Pretty much every router on the market comes with the ability to forward ports, and the Eero Wi-Fi system is no exception, despite its easy-to-use interface.
Firefox Quantum‘s new tab page has a lot of stuff on it, from recommended articles to highlights from your history. But if you don’t like that design, you aren’t stuck with it. You can restore Firefox’s old new tab page, or set any address you like as your new tab.
The Intel Management Engine has been included on Intel chipsets since 2008. It’s basically a tiny computer-within-a-computer, with full access to your PC’s memory, display, network, and input devices. It runs code written by Intel, and Intel hasn’t shared a lot of information about its inner workings.
Firefox Quantum has deep integration with the Pocket read-it-later service, which is now owned by Mozilla. You’ll see a Pocket page action in the address bar, a “View Pocket List” feature in the Library, and recommended articles from Pocket on the new tab page. Firefox offers a way to disable this Pocket integration, but it’s hidden.
