  • Kinto – Easily Get Mac OS Like Keybinds in Ubuntu Linux | UbuntuHandbook

    In this article, we will show you how to create your own abstract graphics using the GNU Image Manipulation Program for abstract graphic design. This program was initially created for Unix-like systems such as Linux. It has also been made available for Windows and OSX users.

  • Vdx - An Intuitive Commandline Wrapper To FFmpeg - OSTechNix

  • Linux Bash Shell Special Characters

    There are a set of characters the Bash shell treats in two different ways. When you type them at the shell, they act as instructions or commands and tell the shell to perform a certain function. Think of them as single-character commands. If you want to master the Bash shell on Linux, macOS, or another UNIX-like system, special characters (like ~, *, |, and >) are critical. We’ll help you unravel these cryptic Linux command sequences and become a hero of hieroglyphics.

    So we found ourselves in the need to delete a considerable amount of files (around 500000, amounting to 1.6T) from an S3 bucket.

  • Use Docker and Alpine Linux to build lightweight containers

    When it comes to Docker, sometimes less is more -- a maxim that applies especially to the base OS images installed in each Docker image.

    The use of a lightweight image -- one with less than 200 MB -- can result in significant resource and cost savings when used alongside optimized applications. A lightweight image also takes less time to deploy compared to a larger one, as it boots up faster.

    Most OS images are lightweight, with minimal compute resource requirements. But others, such as Windows containers, are huge. Alpine Linux is a super lightweight Linux distribution that's useful for Docker containers.

    In this Docker and Alpine Linux tutorial, we'll build an Nginx web server that demonstrates how small a Docker container image can be.

  • Managing resources with cgroups in systemd | Opensource.com

    Cgroups manage resources per application rather than by the individual processes that make up an application.

  • Improve your database knowledge with this MariaDB and MySQL cheat sheet | Opensource.com

    When you're writing an application or configuring one for a server, eventually, you will need to store persistent information. Sometimes, a configuration file, such as an INI or YAML file will do. Other times, a custom file format designed in XML or JSON or similar is better.

    But sometimes you need something that can validate input, search through information quickly, make connections between related data, and generally handle your users' work adeptly. That's what a database is designed to do, and MariaDB (a fork of MySQL by some of its original developers) is a great option. I use MariaDB in this article, but the information applies equally to MySQL.

  • Capturing Decrypted TLS Traffic with Arkime - NETRESEC Blog

    The latest version of Arkime (The Sniffer Formerly Known As Moloch) can now be fed with a real-time stream of decrypted HTTPS traffic from PolarProxy. All that is needed to enable this feature is to include "pcapReadMethod=pcap-over-ip-server" in Arkime's config.ini file and start PolarProxy with the "--pcapoveripconnect 127.0.0.1:57012" option. PolarProxy will then connect to Arkime's PCAP-over-IP listener on TCP port 57012 and send it a copy of all TLS packets it decrypts.

  • How to rebalance your btrfs filesystem on your Linux data center servers - TechRepublic

    The btrfs file system is quickly becoming more widespread.

Games: Stadia, Godot Engine and More

  • Six new games live for Stadia Pro, Super Bomberman R Online now free to play + more | GamingOnLinux

Making the Switch to elementary OS

It all started with an upgrade. In October, 2020 version 20.10 of Ubuntu came out. As I usually do, I duly clicked the button to start the process. That upgrade seemed to go smoothly — everything installed quickly with no conflicts or error messages. I walked away to make a cup of white tea, and when I came back the installation had finished and my laptop rebooted. It was then that I noticed a problem. A fairly big one. Instead of a login screen, I saw a field of aubergine (the colour, not the vegetable). I thought that my laptop was sleeping, so I pressed some keys to try to wake it up. It didn't work. I rebooted, but I was faced with the same problem. Read more
