    linux Author: Bill ToulasTags: , , , , , Comments: 0Published: Apr 08, 2016

    For this tutorial, we will use the Whale Docker image. The Whale is the official mascot of Docker and the Whale docker image resembles the cowsay program which generates ASCII pictures of a cow in the terminal with a message. It can also generate pictures using pre-made images of other animals, such as Tux the Penguin, the Linux mascot.

    linux Author: Bill ToulasTags: , , , , , Comments: 4Published: Apr 05, 2016

    While modern GNU/Linux distributions don't require any use of the terminal, or any knowledge of the bash to offer 100% of their functionality and usability, it is often the case that doing things from the terminal is preferred for a set of reasons.This post is aimed at the people who just want to perform practically useful tasks right from their terminal without having to learn much about command lines.

  • How to Block Email from certain TLDs (Top Level Domains) in ISPConfig

    ispconfig Author: Stephan JauTags: , , , , , , Comments: 2Published: Feb 24, 2016

    Spam is an annoyance and there's a multitude of ways to counteract it. However spammers also get smarter and try to bypass filters and stuff. In addition, ICANN has lately approved a great mean gTLDs (generic Top Level Domains), like .biz, .info etc. Some of those gTLDs are, in my opinion, exclusive used by spammers. Lately, I have gotten a lot of spam from the .xyz gTLD. So the question was, how to block email coming from such domains using that gTLD.

  • An introduction to Linux activity/event trackers

    linux Author: Bill ToulasTags: , , , , , , Comments: 0Published: Feb 18, 2016

    Most modern GNU/Linux distributions use some kind of a software service that tracks the user activities and events. These events can be anything, from the opening of a document file, to the chat conversation. This isn't happening for the purpose to monitor the user and sell this usage data information to 3rd parties, but to help users enjoy a more user-friendly and unified experience across their applications. For example, if you want to quickly locate that document that you opened last weekend, chances are that you will easily and promptly find it after opening your file manager and going to the “Recent” folder.

  • How to use Docker in a practical way (part 1 - Introduction)

    linux Author: Bill ToulasTags: , , , , , , Comments: 3Published: Jan 25, 2016

    It is not an uncommon situation, for early adopters of newly introduced concepts and technologies, to be totally confused when these can fundamentally change the ways of developing and delivering services. Especially when everybody talks about something like Docker, and how awesome and game changing it is. This confusion happens when we try things early on and rushing straight to testing them without grasping the whole concept and background of this newly introduced technology.

  • How to use custom commands in LibreOffice

    ubuntu Author: Bill ToulasTags: , , , , , , Comments: 1Published: Dec 22, 2015

    LibreOffice is one of the most important pieces of free software, allowing many of us to work, study, and share information. Although the software features many tools and capabilities, the spectrum of possible uses for each and everyone out there is so wide, that it is simply impossible to cover every special need with hotkeys and shortcuts. However, LibreOffice can be set to support user-created commands that can essentially help us increase our productivity.

  • How to convert packages between .deb and .rpm

    linux Author: Bill ToulasTags: , , , , , Comments: 1Published: Dec 21, 2015

    Unfortunately, and after years of development in every part of the free software that we enjoy, there are still two primary types of software package available in GNU/Linux systems. The one is the .deb type which is used by Debian and Debian-based distributions like Ubuntu, Mint, and Elementary, and the other is the .rpm type which is used by Fedora, openSUSE, Mageia, and CentOS. Fortunately, there's a workaround for this as we can try to transform the one type to the other.

  • Advanced Audio Control on Linux

    linux Author: Bill ToulasTags: , , , , , , Comments: 0Published: Dec 14, 2015

    Linux audio control is as messed up as the Linux audio system structure. The default and only option of setting the volume level may be enough for the majority of users out there, but it certainly isn't the best when you want to set specific audio levels, or define individual settings for different audio sources, etc. Here is a post on a selection of utilities that could help you get the sound you want on your Linux system.

What is openSUSE?

openSUSE is one of the oldest and most successful GNU/Linux distributions, being initially released in 1994 under the SUSE Linux brand name. It is currently a fully open source and community driven project that is supported by Novell who acquired SUSE in 2003. The particular operating system can be characterized as Linux's “Jack of all trades” as its developers like to combine and implement almost every open source tool and technology that is available at the time of a release. This makes openSUSE powerful and very versatile as an operating system, but also makes it suitable for new Linux users who want to get a full taste of Linux and open source software at once.


Why choose openSUSE?

openSUSE is all about choice and although you may hear a lot of complaints about this exact thing in the world of Linux, the factor of choice never came into play in a better way than the way it comes with openSUSE. You can have whatever desktop environment at its latest stable version, whatever tools and utilities you want, whatever language you need and whatever combination of the above in one single system running without a hinge. This may hinder the coherence of your system, but it will allow you to explore free software in a way that isn't possible through any other distribution.

Speaking about choices, openSUSE can be run pointing at stable and tested software repositories and be upgraded at will, or can be set at “Tumbleweed” that basically transforms the system into a rolling release one that receives constant updates of more edgy package versions and never needs to be upgraded. Moreover, openSUSE can be built from scratch with users choosing the packages that they want and then generate a custom installation CD/DVD through the openSUSE studio web tool!

On the exclusive software side, openSUSE boasts a highly advanced central administration tool called YaST. The YaST serves as a control panel, an RPM package manager, a hard disk partitioning tool, a firewall configurator, user administrator and bluetooth manager. This tool is a true Swiss army knife that can help users perform administrative tasks, maintain their system and secure their data using the same piece of software.

Last, if you are a KDE lover then openSUSE would be a wise choice to go with as it features one of the best implementations of the popular desktop environment. It is often the case that KDE developers run openSUSE for testing and debugging of their work.
