Changing your name on Roblox is an easy process using your Settings page, but you’ll need to pay 1,000 units of Roblox’s in-game currency, Robux, to do it. Here’s how. First, log in to the Roblox website. On the main Roblox page, click the gear icon in the upper-right corner of the screen and select “Settings.” On your Settings page, click the edit button (which looks like a pencil on a sheet of paper) beside your username. In order to change your username, you’ll need to have a verified email address as well as 1,000 Robux. (If you don’t have enough Robux, you’ll see a button that allows you to buy them with real money.) If you do have enough Robux, a pop-up window will appear. Enter the new username you’d like, along with your account password. If the username isn’t taken, you’ll see a green check mark beside it. Click “Buy for R$1,000.” After that, your username will change. Every part of your account will transfer to the new username except for one: Roblox … [Read more...] about How to Change Your Name on Roblox

How to Add a Kids Profile to Google TV
Google TV devices, like the Chromecast with Google TV , are great at surfacing content to watch, but not all of that content is family-friendly. Thankfully, you can set up a specific profile for your kids, complete with parental controls. You can have multiple profiles for everyone in your home on Google TV devices. The Kids profiles have a bunch of extra controls, including bedtimes, viewing limits, app monitoring, and more. Creating a Kids profile will add them as a member to your Google Family . It’s not the same as creating a Kids profile from scratch, as you won’t be assigning them a Gmail address. Let’s get started. RELATED: What's the Difference between Google TV and Android TV?

How to Choose Between Ubuntu, Kubuntu, Xubuntu, and Lubuntu
There’s more than one Ubuntu. You can download Ubuntu, Kubuntu, Xubuntu, or Lubuntu: But what’s the difference, and which should you choose? The answer depends on what you’re looking for: Linux is all about choice. What’s the Difference? To pick properly, you’ll need to understand the strengths of each “flavor.” That might be the bling and polish of Kubuntu, the “set it up and forget about it” of Ubuntu, the retro simplicity and stability of Xubuntu, or the ability of Lubuntu to run on older and less powerful hardware. Despite the different names, all of these are based on the same underlying Ubuntu software. They include the same Linux kernel and low-level system utilities. However, each has different desktop and flavor-specific applications. That means that some are more full-featured, while others are more lightweight—so each feels a little different. Since these flavors are built to make Linux more accessible, they’re not necessarily going to score upvotes in a geeky … [Read more...] about How to Choose Between Ubuntu, Kubuntu, Xubuntu, and Lubuntu

How to Manage Linux Servers with the Cockpit Web Interface
You can easily monitor and manage multiple Linux computers with Cockpit, a browser-based administration and dashboard tool. It’s self-contained, simple to set up, and easy to use. We’ll show you how to get started. Managing Multiple Linux Servers If you have multiple Linux computers or servers to monitor, you have a challenge. This is especially true if some of them are running as headless systems with no monitor attached. For example, you might have rack-mounted or remote servers located in different buildings or a collection of Raspberry Pi’s scattered around your home. How can you monitor the health and performance of all of these? If you use Secure Shell (SSH) to connect to them, you can run top or another terminal-based monitoring tool. You’ll get some useful information, but each tool has its own specific area of interest. It’s awkward to have to move from tool to tool to view the different metrics of your remote Linux computer. Unfortunately, there’s no … [Read more...] about How to Manage Linux Servers with the Cockpit Web Interface
