We’ll show you how. Is Downloading Thumbnail Images Legal? As of this writing in August 2021, there’s no option on the YouTube site or in the YouTube mobile app to download video thumbnails.

Docker containers aren’t just about isolation—they’re often used to manage processes that still need to talk to each other directly. But, to communicate, you’ll often need to know each container’s IP address, which you can find with a few commands. Consider Using a User-Defined Bridge Docker networking is a little complicated. Containers launched by default will be placed in the default “bridge network,” and are allowed to communicate with other containers directly, provided you have their private IP address....

Are you comfortable with Linux/Unix and want SSH access to your Windows 7 machine? Cygwin provides this functionality and gives you a familiar environment to work with in a few simple steps. We’re assuming you’ve got Cygwin installed and configured. If not, check out our article, How To Use Linux Commands in Windows with Cygwin to get started. Installing OpenSSH OpenSSH is what we’ll be using, so if you don’t have it installed, find Cygwin’s setup....

Docker gives you everything you need to build and run containers on your Linux system. Containers are similar to lightweight virtual machines. They let you create portable application images which run using your host’s operating system kernel. You can use Docker on Debian, Fedora, CentOS and Raspbian platforms. Derivatives of those distributions will work too. Docker provides x86/x64 and ARM builds for most supported platforms. We’re using a Debian system with the apt package manager for this guide....

Google Duo is one of the easiest video chat apps out there, but it’s not only for video. You can make audio-only calls, too, and the sound quality is much better than a typical phone call’s. We’ll show you how. Like with video calls, the voice calling feature works on iPhone, iPad, Android phones and tablets, and computers through a web browser. It’s just a matter of choosing “Voice” instead of “Video” when starting a call....

Windows 8 has a new feature that allows you to natively pin both applications and folders to the Start screen. This is an improvement over Windows 7, which requires third party tools to pin folders to the Start menu. To pin an application to the Start screen, open Windows Explorer by clicking on the Windows Explorer tile in the lower, left corner of the Start screen. If you’re on the Desktop, Windows Explorer is accessible on the Taskbar, just like it is in Windows 7....

Access an encrypted home directory when you’re not logged in – say, from a live CD – and all you’ll see is a README file. You’ll need a terminal command to recover your encrypted files. You should also back up your mount passphrase ahead of time – you may need this in the future. While eCryptfs normally decrypts your files with your login passphrase, the mount passphrase may be necessary if eCryptfs’s files become lost....

Windows 8’s Modern interface includes support for running two Windows 8 apps side-by-side. This feature, named “Snap,” isn’t explained in the tutorial – you’ll have to know it exists to make use of it. While the multitasking may be limited compared to Windows desktop multitasking, it’s more flexible than iPad and Android tablets, which can only have a single app on the screen at a time. Note: Snap only works on monitors that are at least 1366 pixels wide....

Want to secure your SSH server with easy-to-use two-factor authentication? Google provides the necessary software to integrate Google Authenticator’s time-based one-time password (TOTP) system with your SSH server. You’ll have to enter the code from your phone when you connect. Google Authenticator doesn’t “phone home” to Google — all the work happens on your SSH server and your phone. In fact, Google Authenticator is completely open-source, so you can even examine its source code yourself....

A regular Nextcloud installation can be time-consuming to set up. Nextcloud is built on the classic LAMP stack, so you’ll need Apache, PHP, and MySQL, each with its own prerequisites. This can make it tricky to maintain the installation or use it alongside other workloads on your server. Running Nextcloud as a Docker container simplifies the setup procedure and lets you isolate the installation from your other applications. Nextcloud has an official Docker image, which we’ll focus on in this article....

Software supply chain security has become topical in the wake of high profile dependency-based attacks. Producing an SBOM for your software artifacts can help you identify weaknesses and trim down the number of packages you rely on. A new Docker feature integrates support for SBOM generation into the docker CLI. This lets you produce an SBOM alongside your build, then distribute it to consumers of your image. The “docker sbom” Command The new docker sbom command is bundled with Docker Desktop versions 4....

Using SSH keys is more secure than passwords, and that applies to Git as well. Unlike a password however, it’s harder to change your SSH key, or manage multiple keys. By editing your SSH config though, you can connect to multiple Git repositories with different keys. How Does SSH Work With Git? Git doesn’t just use your private key to authenticate when you use SSH instead of HTTPS—it actually establishes a real SSH connection to the remote server....

RSS feeds are great for getting alerted to new articles on your favorite sites. But your personal time shouldn’t be taken up with reading work articles. Split your professional and personal subscriptions by adding work feeds to Microsoft Outlook instead. Managing feeds in Outlook is super easy, although it can only be done in the desktop Outlook client. If you only use the Outlook web app, there are plenty of other good feed readers, like Feedly or Inoreader, to choose from instead....

Taking screenshots is pretty easy; it’s a feature built into most operating systems. If you’re already working on a Word document, though, and want to add a screenshot to it, you can save yourself a few clicks by using Word’s built-in screenshot tool.

Installing Active Directory on Server Core is not a task that can be achieved using the Optional Component Setup tool–instead we actually have to use DCPROMO from the command line. Here’s how to do it. Note: this is part of our ongoing series teaching IT administration basics, and might not apply to everybody. Before we install Active Directory there are a few things that need to be done first–we need to set static IP information for the network adapter as well as change the name of our server....

The dash on Ubuntu’s Unity desktop allows you to search for applications, files, music, and videos – but you’re not just limited to these. Install custom lenses and scopes to extend the dash with more features. Most additional lenses and scopes are currently found outside the official repositories. Unfortunately, many useful lenses, including the dictionary lens, books lens, and Tomboy notes lens, aren’t yet available in PPAs for Ubuntu 12....
