  • How to Install Shutter on Ubuntu from an Official PPA

    The legendary Shutter screenshot tool is back from the dead and once again available to install on the Ubuntu desktop.

    Fresh off the back of its GTK 3 port, new builds of the go-to screen capture n’ annotation tool (it does more than just take screenshots, as we’ll get to) are being packaged for Ubuntu and related Linux distros through an official PPA.

    Yes, official.

    If you read this site regularly you might recall we wrote about a half-broken Shutter Snap app (totally unofficial and very unstable) a year or so back. Forget about that — sudo rm -rf forget.

  • 7 Tips to Speed Up Tor Browser - Make Tech Easier

    Tor preserves your online anonymity through its unique onion routing, in which your encrypted data passes through several intermediary nodes. None of the nodes know anything about the origin of your data or your final destination, thus protecting your identity, but this process can reduce your browsing speed, and ISPs can throttle Tor traffic without warning. The following tips below will help speed up the Tor browser and make it faster.

  • How to Enable ZFS Deduplication

    The deduplication feature of the ZFS filesystem is a way of removing redundant data from ZFS pools/filesystems. Simply put, if you store a lot of files on your ZFS pool/filesystem, and some of these files are the same, only one copy of these files would be kept on the ZFS pool/filesystem. The rest of them will be a reference to that copy of the file. This will save a lot of disk space on your ZFS pool/filesystem.

    Technically, when you copy/move/create new files on your ZFS pool/filesystem, ZFS will divide them into chunks and compare these chunks with existing chunks (of the files) stored on the ZFS pool/filesystem to see if it found any matches. So, even if parts of the file are matched, the deduplication feature can save up disk spaces of your ZFS pool/filesystem.

  • How to Get Full Screen in Ubuntu Virtual Box

    Virtual Box is free software that allows you to virtualize the x86 computer architecture. The “host” is the operating system on which Virtual Box runs. Virtual Box can run on Windows, Linux, or macOS as its host operating system. Virtual machines (VMs) can run numerous operating systems on a single physical computer, storage capacity, time, and financing costs.

    Virtual machines enable legacy applications to run on new software, lowering the cost of migration. In this guide, we have installed Ubuntu 20.04 Linux system on the Oracle Virtual Box. The Virtual Box comes with a lot of features. One of them is its full-screen mode. By default, Ubuntu 20.04 Linux system on the Oracle Virtual Box opens up with the windowed mode. While the guest OS is operating, Oracle VM Virtual Box generates a separate environment for it. We can change it into full-screen mode as well. Follow this guide to switch from windowed mode to full-screen mode and full-screen mode to windowed mode, as well.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • 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.
