  • How to install Telegram on Ubuntu 22.04 | 20.04 LTS - Linux Shout

    Learn the easy steps to install Telegram messenger on Ubuntu 22.04 Jammy JellyFish or 20.04 Focal Fossa Linux desktop for chatting, voice call, and much more…

    If you are familiar with WhatsApp, then Telegram would not require a detailed introduction because it is a similar kind of application. Similar to WhatsApp, users can install Telegram on their smartphone and get registered using the cell phone number to chat with other users of Telegram. You can share or download images, videos, documents and files very easily via it. Further, it is also possible to make video and voice calls, create polls, groups, and channels to connect with each other. Telegram is particularly popular because of the latter function.

    One of the popular features that make Telegram popular is its subscription system for channels, which works similarly to YouTube: according to your interests, you can subscribe to channels in Telegram. If the channel operator posts new content, you can see it in the chat overview. Users can easily select posted content and forward it to family and friends. This makes it clear from which user or channel the content originally comes. In this way, you can quickly find new channels for your own interests. Also, it offers broadcast functions as WhatsApp has.

    Those who are a fan of stickers will love Telegram. Messenger has an incredible number of animated stickers that you can download as a pack and share with others. If that’s not enough, you can also search for GIFs.

  • Collect sudo session recordings with the Raspberry Pi | Opensource.com

    I've used the sudo command for years, and one of my favorite features is how it saves a record of everything happening in a terminal while running a command. This feature has been available for over a decade. However, sudo 1.9 introduced central session recording collection, allowing you to check all administrative access to your hosts on your network at a single location and play back sessions like a movie.

    I use this feature on my Raspberry Pi, and I recommend it to other Pi users. Even if you fully trust your users, logs and session recordings can help debug what happened on a given host if it acts strangely: Oops, wrong file deleted in /etc.

    Dual booting is a great way to get the best of both worlds of Windows and Linux. It’s relatively straightforward to install the two operating systems alongside each other, and it's also a great opportunity to learn more about computers and how software works.

  • How to Use Docker to Package CLI Applications – CloudSavvy IT

    Docker is a popular platform for packaging apps as self-contained distributable artifacts. It creates images that include everything you need to run a particular software, such as its source code, third-party package dependencies, and required environment characteristics.

    As Docker images can run anywhere Docker’s installed, they’re a viable format for distributing your CLI applications. The Docker ecosystem includes Docker Hub as an available-by-default public registry, giving you a complete tool chain for publishing, updating, and documenting your tools.

    Here’s how you can use Docker to package CLI apps instead of traditional OS package managers and standalone binary downloads.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
