Together they continue the work started at Open Whisper Systems , one of Rosenfeld’s earlier start-ups. The Signal application is free and open source. Anyone can review the source code. The source code for the Signal Messenging Protocol (SMP) was reviewed by a joint team from the German CISPA Helmholtz Center for Information Security , the Swiss ETH Zurich University , Cisco , and the Canadian University of Waterloo . They declared the code clean, the motives pure, and the encryption rock-solid. Signal is … [Read more...] about How to Install Signal Desktop on Linux

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
End-to-end encryption (E2EE) ensures that your data is encrypted (kept secret) until it reaches an intended recipient. Whether you’re talking about end-to-end encrypted messaging, email, file storage, or anything else, this ensures that no one in the middle can see your private data. In other words: If a chat app offers end-to-end encryption, for example, only you and the person you’re chatting with will be able to read the contents of your messages. In this scenario, not even the company operating the chat app can see what you’re saying. Encryption Basics First, let’s start with the basics of encryption. Encryption is a way of scrambling (encrypting) data so that it can’t be read by everyone. Only the people who can unscramble (decrypt) the information can see its contents. If someone doesn’t have the decryption key, they won’t be able to unscramble the data and view the information. (This is how it’s supposed to work, of course. Some encryption systems have security flaws … [Read more...] about What Is End-to-End Encryption, and Why Does It Matter?
Secretly playing your Nintendo Switch can be difficult because, by default, Nintendo alerts all of your friends when you launch a game, and they can see if you’re online from their friends list. Luckily, you can always appear offline if you choose. Here’s how to set it up. First, wake up your Switch and press the “Home” button. On the Home screen, select your user profile icon, which is located in the upper-left region of the screen. Next, you’ll see your profile page. In the sidebar menu, choose “User Settings.” In “User Settings,” scroll down the page and choose “Friend Settings.” In “Friend Settings,” select “Display online status to.” In the “Display online status to” menu that pops up, select “No One.” (Alternately, you could decide to only share your online status to friends marked as “Best Friends.” In that case, select “Best Friends” here.) After the change is registered, you’re free to exit your profile settings. From now on, your Nintendo Switch … [Read more...] about How to Appear Offline on Nintendo Switch
If you’re sharing your screen during a video conference, it’s important to make sure no notifications appear. This can prevent the accidental leaking of confidential information to others—or just save you from a world of embarrassment in your next Zoom, FaceTime, or Skype video call. Try Video Conferencing Tool’s Built-in Option Depending on which video conferencing tool you’re using, you may be able to enable a setting that blocks certain notifications. Zoom, for example, lets you block system notifications while you’re sharing your screen. You’ll find this option at Settings > Share Screen > Silence system notifications when sharing desktop. The problem is that it doesn’t always block all notifications—Slack DMs and Skype messages being among those notifications that still get shown while sharing your screen in Zoom. While it may be inconvenient, the most effective way to ensure no embarrassing or confidential messages are shared during virtual meetings is to mute … [Read more...] about How to Hide Notifications While Sharing Your Screen in a Video Call
